2 INTRODUCTION

ORTEC® Detective

® series, Detective EX/DX

® series handheld and Detective

®-200 high-purity

germanium (HPGe) radioisotope identifiers (RIIDs) are widely used around the world by law

enforcement, security agencies, military and customs agents in the fight against illicit nuclear materials

trafficking.

ORTEC® Detective identifiers and the Detective

®-SPM spectroscopic portal monitor combine the

superior resolution of HPGe detectors with the speed and accuracy attributable to ORTEC® advanced

algorithms to be the most accurate and sensitive means for search and identification of radioactive

material.

Incorporation of Detective®-200 rugged identifiers and comprehensive GPS location mapping capability

with powerful software makes the Detective-Remote® Search System effective for mobile search and

identification on land, sea, or air.

To summarize Detective-Remote® provides real-time radionuclide detection and identification for

Homeland Security, Customs and Emergency Response in mobile or stationary monitoring applications.

Detective-Remote® System Applications

� Mobile Surveys –Detective-Remote® analyzes for the presence of radionuclides as it is

transported through areas of interest.

� Stationary Monitoring –Detective-Remote® is used for static monitoring at chokepoints for

pedestrians, autos, trucks or boats.

Detective-Remote® System Features

Available system configurations and mounting options are flexible and subject to change without notice.

See our website or contact your ORTEC® Representative for current product information.

� When purchased with Detective® instruments, Detective-Remote

® is shipped as a turnkey

solution, factory-configured and ready to use after the Detective® units are powered and cooled.

� Detective-Remote® performs searches in energy, time, and position for the highest probability of

detection of point-source or distributed radionuclides.

� Fixed or flexible arrays of Detective® subsystems

2. Each Detective

® unit is comprised of an

HPGe detector, Stirling cycle cooler, an integrated computer and application interface.

� Integrate your existing ORTEC® portable identifier or IDM into a Detective-Remote

® system.

Consult Appendix B.1 to determine the compatibility of your identifier with the system. Contact

your ORTEC® Representative or our Technical Services Group to obtain the necessary software.

2 The Detective-Remote system is designed for use with ORTEC

® ultra-sensitive Detective

®-200 identifiers.

Detective®- Remote may be integrated with a variety of other Detective® series instruments into a system. In this

manual, the term detector subsystem is used when emphasizing the hardware or software components of the

standalone, intelligent identifiers.


10

� Data streaming from detector groups in 1-second, loss free measurements, are analyzed as a series

of rolling-average data integration windows. These data integration windows, hereafter referred

to as “data integrators”, are set for multiple strategic time periods for data analysis. Detective-

Remote® combines the data from multiple detectors for the most sensitive, accurate detection and

identification capability.

� All survey and analysis data, including spectra, gross gamma count rates, (and optionally neutron

count rates3) GPS locations, and radionuclide identifications, are captured in a Microsoft SQL

Server database. A new database is created and saved for each survey.

� Integral GPS and mapping software provide a complete history of the survey route and source

locations. Detective-Remote® is supplied with the OpenStreetMap (OSM) open-source world

map software4.

� Detective-Remote® is compatible with other map systems including ESRI Shape File, Oracle

JNDI, PostGIS, H2, GeoTIFF, ArcGrid, Gtopo30, ImageMosaic, WorldImage, WMS, Bing

Maps, and Google Maps.

� Email-based reach-back simplifies communicating field data to anyone with internet email

access.

� IEEE 802.11 wireless or wired USB communication may be used to transfer data from detectors

to the host computer(s). Both wireless and wired connection types may be used simultaneously.

� Easy-to-use software interface with extensive rollover “tool tips” describing the controls and

tools.

� Flexible user interface lets you customize the data views available in idle, search, stand-in, back-

ground, and review modes.

� Optionally generate ORTEC® .CHN-format survey and background spectra from the Spectrum or

Reach-back tab for any system detector. These spectrum files can be viewed with the

accompanying MAESTRO® MCA Emulation Software or its WINPLOTS spectrum plotting

program. The –CHN spectrum output may also be read with Peak Easy.

� An experienced spectroscopist can use the LCX (Low-Confidence Expert) identification mode

(see Section 4.3.3).

3 Helium-3 neutron detectors currently have restricted availability. Please contact your ORTEC

® Sales

Representative to determine their availability for your application. Alternative Li6 Neutron detector panels are

available for inclusion into the Detective® Remote system.

4 Open source map contents subject to change without notice.

One- and Two-Computer Configurations

In the standard configuration, all computer software components are installed and run on a single

computer.

In the optional two-computer configuration, the User Interface program runs on computer #1, (the user

interface computer); and the Analysis, Database Maintenance, and GPS Server programs run on computer

#2 (the analysis computer). Both computers have the complete Detective-Remote® software suite, but

Microsoft SQL Server 2012 and map software are installed only on computer #2.

During initial installation, computer #2 (the analysis computer) is configured to receive the stream of

survey data provided by computer #1 (the user interface computer) through computer #2’s ad hoc wireless

network. This setup is the same whether detectors are connected to computer #1 via IEEE 802.11 wireless

or USB connections. An alternative is to connect computers 1 and 2 via wired Ethernet.

Setting up additional User Accounts — The Detective-Remote® computer(s) are factory-configured with

a Detective-Remote® user account. You may create additional accounts tailored for different detector and

group configurations. Contact your ORTEC® representative or ORTEC

® Technical Services Group for

more information.

Low Maintenance, 24/7 Readiness — ORTEC® Detective

® series instruments are essentially

maintenance- free as they have no user-serviceable components and are designed for years of continuous

duty. The instruments do not need to be returned to factory for calibration as this function is readily

performed by the user or in newer models it is done automatically when the background is performed.

Between uses, these units should be connected to an external power source with the coolers running to

keep the detector at operating temperature.

Computers and network hardware can be powered off and on as needed.

2.1 Hardware and Software Components 5

� One to eight Detective®-200s or compatible detector subsystems, factory-configured with all

supporting Detective-Remote® software applications.

� One or two 64-bit Microsoft Windows 7 computer (s) running the Detective-Remote® application

and ancillary software.

� Garmin GPS 18x USB global positioning device or equivalent.

� A valid TCP/IP network that connects all of the computers and detectors. The network can be

wired; or IEEE 802.11 wireless using either ad hoc (peer-to-peer) or infrastructure (point-source)

mode. The computer(s) and detector(s) can be connected via USB cable, or a combination of

wired - USB and wireless - TCP IP LAN connections may be used.

3 PREPARING FOR FIELD USE

This chapter highlights the steps involved in Detective-Remote® system setup and includes references

where to find additional detail information in subsequent chapters and appendices. These instructions

assume you will initially be setting up the system indoors to test component connectivity, configure the

user interface, and seed (pre-cache) the map for your local search area. However, all the setup steps may

be performed in the search vehicle, one exception being that the analysis computer must temporarily be

connected to the internet for map seeding.

Most users will have a one-computer system, and can ignore dual system setup reference to

“analysis computer” and “user interface computer,” which apply only to the dual computer setup.

3.1 Detector Cool down — TIME: 8–24 hr

Collect the hardware manuals for all portable identifiers (with integrated computer) and interchangeable

detector modules, (no computer) hereafter referred to as “IDM’s”. For the IDM, you must know how to

apply power, and turn the unit on to begin cooling the detector. For the identifiers, you must know how to

connect them to external power, start the ORTEC® Launcher application then start the unit’s identifier

application to turn on the cooler, monitor the hardware status screen during cool down, and exit to the

Launcher or to Windows Mobile. It will also be good to know the anticipated time required to cool and

charge the internal and auxiliary battery for each type of instrument.

While the detectors are cooling, continue with system preparation and ignore any “system alarms” in the

“Detective-Remote® User Interface” program.

3.2 Start Computer(s) and Prepare Mapping — TIME: 1–6 hr

For wireless systems, start the analysis computer first and log in on the Detective-Remote® user account.

The factory default password is “ORTEC” (all uppercase, no parenthesis). Follow the instructions in

Section 5.2 and Appendix B for instructions on how to connect to the wireless LAN.

In 2 computer systems next, start the user interface computer and log in using the same credentials.

3.3 The Default Open Street Map

When using the default OpenStreetMap (OSM) map, it is already installed on the analysis computer and

pre- configured. OSM should be ready for you to pre-cache (seed) the map tiles for your planned search

area — that is, download them from the ORTEC® mapping service for offline (field) use

6. After any map

download for a particular area, the information is retained in the database for future use without seeding.

See Section 9.3 for seeding instructions.

6 Detective-Remote can also access the map server in real time (where signal strength permits) if you have a cellular

modem or are tethered to a mobile phone. However, the turnkey Detective-Remote system does not have real-time

access, so this manual discusses pre-caching. Consult your IT department or our Technical Services Group for more

information on real-time access.


14

3.3.1 Installing Your Own Map System— TIME: 0.75–1 hr

If using your own map, you must first copy it to the analysis computer (Section 9.2). It is then treated as a

layer on the Map tab, and can be turned on and off, and optionally used in combination with the OSM

map and other map layers. NOTE: Alternate map layers are stored in their entirety on the analysis

computer. Therefore, if you intend to use only your added map layers, rather than the default OSM, there

is no need to connect to the internet and download a cache of map tiles from the map server before going

into the field. However, if you plan to use the OSM as well as your own map(s), you must pre-cache the

OSM tiles.

3.4 Integrate Additional Detector Modules into the System TIME:0.5–0.75 hr

/detector

If you will be adding other identifiers or interchangeable modules to the system, follow the procedure in

Appendix B for each new wired or wireless detector connection7. The final step of this procedure will be

to run the Setup and Options program, as discussed in Section 3.5 below.

Note: You can temporarily remove your standalone identifier (e.g., Detective® or trans-SPEC series units)

from the Detective-Remote® system to take a closer look at an object of interest. For additional

information see Appendix B.

3.5 Connect the Detectors to the Computer — TIME: 0.5–1 hr

3.5.1 Wired Systems

On startup, the identifier touchscreens should show the Mobile MCB Server set to the USB Control

option (see Figure 7). Detective®-100 and trans-SPEC-100 series units must be wired from the rear-panel

CONTROL port to the analysis computer. All other identifiers have only one USB port. Cable all

interchangeable detector modules from the USB connector to the analysis computer.

If this is a turnkey system and you are not adding more detector modules to it, skip to Section 3.6. If you

have added more detector modules to your system (Section 3.3), you are now ready to start the Setup and

Options program (Section 3.5).

3.5.2 Wireless Systems (Identifiers Only)

On startup, the touchscreen should show the Mobile MCB Server set to the Wireless/ActiveSync option.

The identifiers should connect to the analysis computer’s ad hoc network within a few minutes.

If this is a turnkey system and you are not adding more detector modules to it, skip to Section 3.6. If you

add additional detector modules to your system follow instructions in (Section 3.3 and Appendix B) to

incorporate them into the system. You are now ready to start the Detective-Remote® “Setup and Options”

program (Section 3.5).

7 After you integrate an additional identifier into Detective-Remote, you can remove it for use in its standalone

portable identifier mode, then reconnect it. In standalone mode, you can perform any function in the various

identifier/ spectroscopy applications, including running backgrounds, without any effect on Detective-Remote.

Likewise, none of the Detective-Remote settings affect standalone identifier operation.


15

3.6 Run the Setup and Options Program — TIME: 0–0.25 hr

There are limited circumstances which require the user to access and make changes through the “Setup

and Options” program. Those circumstances are as follow:

• On first startup of a new system to modify data integration times, detector group assignments, or

reachback settings.

• To enable a new detector in the system and assign it to one or more detector groups.

• If you add a new detector module to an existing system, you need visit the “Startup” and

“Detector Groups” tabs in the “Setup and Options” program.

• After installing an upgrade of “Detective-Remote®” software.

• To acknowledge multiple outstanding alarms from the last work session (for instance, if you

trigger a series of hardware alarms by using the computer[s] without the detectors, e.g., for survey

review).

NOTE: There are three general interfaces within Detective-Remote®

1) System Startup, which launches /marshals various programs to incorporate their functionality,

including GPS, data acquisition, database management etc.

2) Detective-Remote® User Interface, This interface allows the operator will run the program.

3) Set up and Options. This is the location where changes in the setup control how Detective-

Remote® User Interface operates.

Anytime “Set up and Options” is accessed the two other interfaces must be closed (shutdown) or changes

made will not take effect.

The Detective-Remote® “System Startup” program automatically starts each time the computer is booted,

therefore, the first step is to close it by hovering the cursor above the DR icon ( ) in the system tray.

When the popup appears, click the (×) in the upper-right corner to close. Shutdown takes about 5 seconds

after this is done.

If the “Detective-Remote® User Interface” program is open, it will also need to be closed before making

changes to “Detective-Remote® Setup Options” program.


16

Start the Detective-Remote® Setup and Options program. Before the first use of a new system, check the

settings tabs as follows.

• Startup — Verify that all of the detectors in your system are listed in the Detectors section, and

that the checkbox beside them is marked. Otherwise, they will not be used for data collection.

• Detector Groups — On factory-configured Detective-Remote® systems, an “ALL” detector group

(containing all the system detectors) is defined at the factory. To create one or more new detector

groups, or to add a new detector to existing groups, see Section 3.4, and Appendix B. If any of the

detectors you plan to use are missing from the list or are displayed in red, go to Section 5.3.3, to

troubleshoot.

• Display — To change the default settings in DR setup, see Section 5.3.2. For additional

information on setting up the display screen in the User Interface, refer to Chapter 5.

• Acquisition — The default background count time is 1200 seconds. Your CONOPS will

determine the length of your minimum background count period; we recommend 1500 seconds as

a minimum. The “suppress background ID alarms” option is enabled by default to minimize

nuisance alarms. To change the default settings, see Section 5.3.3. For more information about

performing a background measurement refer to section 7.2.

• Alarms — The optional speed-limit alarm default setting is 8 mph (13 kph). To change the alarm

speed, see Section 5.3.4.

• Integration Times — ORTEC® strongly recommends that initial use of the default, general-

purpose 8- and 30-second integrators. Be sure to read the system concept and integration time

discussions in Chapter 4.

• Reach-back — Optionally enter a reachback recipient’s email information, refer to Section 5.3.6

for details.

• Status Graphics — Controls the appearance of the User Interface program’s Status tab. To

reposition the detector group icons and/or change the “vehicle” .JPG, see Section 5.3.9.

• Manage Surveys - Survey database file exports, imports and deletions are performed using the

“Manage Surveys” tab, see Appendix C.

• You are now ready to close “Setup and Options” and start the “System Startup” program. If you

have not entered an email “Recipient” in reach back settings, a pop-up reminder will be displayed

when you exit the Setup and Options program. Click “No” to ignore the message and close

“Setup and Options”.


17

3.7 Start the System Startup Program — TIME: 0.1 hr

On the analysis computer, start the Detective-Remote® System Startup program, wait for it to initialize

and display the DR icon ( ) in the system tray. Click the icon, and ensure all items on the popup

window have a green check mark. If any of the System Startup components have a problem, the DR icon

will be flagged with a yellow caution indicator.

• If any of the detectors show a yellow or red icon, go to Section 5.4 for troubleshooting

instructions.

• If the icon for either of the top two entries is yellow or red, contact our Technical Services Group.

• If the GPS antenna is disconnected from the analysis computer, the DR icon will be flagged with

a yellow caution, the GPS Server entry on the DR popup will display a yellow indicator, and the

Franson GpsGate tray icon will be red ( ). When the system is mounted in the survey vehicle

and the GPS antenna is connected (Section 5.5) and receiving satellite signal, the Franson Gps-

Gate icon and GPS Server indicator will turn green.

IMPORTANT:

Leave the System Startup program running. It must run together with the User Interface program in order

to analyze detector data streams for IDs and alarms, capture comments, record GPS coordinates for each

measurement (where GPS signal can be detected), and save survey and background data to the survey

database. If “Detective-Remote® System Startup” is accidentally closed during a survey, the User

Interface will continue in Survey Mode, but no data analysis will take place and the search will be invalid. If it is inadvertently closed follow these steps,

1) End the search,

2) restart System Startup,

3) restart the survey.

3.8 Start the User Interface Program — TIME: 1 hr

Start the User Interface program on the User Interface computer. The “User Interface” application has

five modes (Idle, Background, Search, Stand-in, and Review); and 10 data display tabs (Detectors,

Measurements, Events, Alarms, Detector Health, Strip Charts, Status, Map, Spectrum, and

Reachback). Not all data display tabs are available in all modes, there is a reference table of tabs

available from each mode in the overview of major screen features in Section 6.1.

The Detective-Remote® User Interface into the mode last used. Whenever possible return to “Idle” mode

before closing the program. A new system opens the first time in Idle mode, with the Detectors tab

displayed on the left side and the Detector Health and Events tabs on the right. The Detectors tab should

show a detector status indicator for each detector in the system. When the system is ready for radiation

surveying, all status indicators will have a white background and the lower-left corner will indicate Idle

mode, as shown in Figure 37. See also Figure 38, which shows examples of detector operational and error

states.

• If a status indicator is amber and indicates a communication error, go to Section 6, and

troubleshoot.

• If an indicator is amber and indicates a warm detector, allow the system to continue cooling

• If an indicator is amber and indicates an expired background, gain stabilizer, or FWHM error,

ignore for now; these will be resolved when you perform the Background measurement.

• Each mode (Idle, Search, Stand-In, Background and Review) has its own default selection and

layout of tabs. Add as many as you wish from the tab selection list (see Figure 28), and arrange

them as needed (Section 6.3).

• After all detector temperature errors are resolved, click the Background button. You may wish to

add the Detectors tab to the Background mode and monitor the status messages. To do this, click

the upper-right Show... button and click Detectors Tab.

• At the end of the Background measurement, the system will automatically return to Idle mode.

• On the Detectors tab, ensure all expired background, gain stabilizer, and FWHM errors are no

longer displayed, all backgrounds are white, and all are in Idle mode. If any detectors still show

errors, contact your ORTEC® Representative or Technical Services Group.

*** You are now ready to transfer the system to the search vehicle ***

3.9 Mount the System in the Search Vehicle — TIME: Variable

Two options for placing system in the vehicle:

One option is to leave the hardware and software running in its current state and migrate it to the vehicle.

Second option is to lose “Detective-Remote® Startup” by hovering over the DR Icon in the tray and when

the status box appears click the “X” in the upper right corner to close. Shutdown the computer.


19

In wired systems, disconnect the detectors from the analysis computer, install the units, in the vehicle and

reconnect. Mount the laptop in the vehicle and attach the GPS antennae. Start the computer and launch

the Detective-Remote® “System Startup”. Most often DR will reestablish network communication within

about 5 minutes.

In wireless systems install the units in the vehicle, mount the laptop, install the GPS, then start the

computer. Launch Detective-Remote® “System Startup”. Most often DR will reestablish network

communication within about 5 minutes.

However, if communication with all identifiers is lost, follow the troubleshooting instructions in Section

10.

Connect the GPS antenna to the analysis computer (if it is not connected, or is connected to the user

interface computer, no map data will be collected during surveys). For best results mount the antenna on

the outside of the vehicle although for temporary installations mounting in the dashboard of the vehicle

may work adequately.

When connected the Franson GpsGate tray icon will change from red to green ( ) and the DR icon will

no longer display the yellow caution indicator. (If the Franson GpsGate icon remains red, see the

troubleshooting steps in Section 10.3.)

On the User Interface computer, click the Detectors tab and confirm all “detector status” indicators are

white and in Idle status. Acknowledge any alarms.

You are now ready to perform an initial search, preferably with a test source, to familiarize yourself with

system behavior and the appearance of alarms on the various tabs. Choose the tabs you wish to display in

the various modes. The Detectors, Events, and Map tabs are displayed by default for both Search and

Stand-In surveys. You may also wish to display the Alarms, Charts, Status, and Measurements tabs.

3.10 Survey Site Background Measurement — TIME: 0.75 hr

The first steps when you arrive at the survey location will be to obtain a GPS fix then perform a

Background measurement (See Chapter 7).

*** Your system is now ready for radiation monitoring. See Chapter 8 ***

4 OVERVIEW AND KEY CONCEPTS

This chapter discusses the key concepts to data collection and analysis in Detective-Remote®.

Additionally it provides an introduction to the system’s software components and operation modes; and

discusses alarms and alarm, data management, and system operating cautions and limitations.

4.1 Problem and Solution

Wide-area radiation searches pose a substantial four-dimensional challenge. Depending on the situation

and survey site, objects of potential interest may be in orderly arrays at known distances in a well-defined

area (e.g., rail cars, a harbor of closely moored ships, containers stacked in a freight yard), or sparsely and

randomly scattered across broad expanses of soil or water, or secreted in one vehicle somewhere among

thousands at a major city’s holiday celebration.

� How do you sweep miles of territory for one or multiple threat radionuclides at one or multiple

distances?

� How do you isolate a threat identification apart from all of the innocent radiation sources

surrounding us?

� How do you collect and analyze the survey data to solve this four-dimensional problem?

The solution to these challenges is the Detective-Remote® Mobile Search System: Comprised of one to

eight of our Detective®-200 high-resolution HPGe identifiers mounted for mobile survey, and coupled

with GPS and a mapping capability.

Detective-Remote® can utilize almost any map system, including but not limited to OpenStreetMap (the

system default), or your ESRI Shape File, Oracle JNDI, PostGIS, H2, GeoTIFF, ArcGrid, Gtopo30,

ImageMosaic, WorldImage, WMS, Bing Maps, or Google Maps.

You deploy the Detective® instruments in pre-defined groups (say, one group of eight forward-facing; or

two groups of four, left-facing and right-facing). Each detector continually streams spectral data, which

the software analyzes approximately once per second. The net result of each once-per-second evaluation

of all integration times for all groups is called a “measurement”. Each measurement in a survey is

numbered and tracked on the User Interface program’s Measurement tab (see the left side of Figure 39).

The stream of measurements for all detectors in a group are combined and simultaneously analyzed as a

rolling series of shorter-duration windows and longer-duration windows.

You select the duration of the rolling analytical windows, which we will call “data integrators”. The

selection of data integrator windows will be based upon your knowledge of:

1) The speed at which the survey will be conducted.

2) The expected distance(s) between source(s) and the detector group.

3) The detector group’s “effective” field of view (FOV).

The “effective” FOV is dependent upon the horizontal and vertical spacing of the detectors.


21

These factors allow you to estimate the number of seconds that sources will be in the detector group’s

“effective” FOV at varying distances. As a rule of thumb, short-duration analyses will tend to identify

sources closer to the detectors while longer-duration analyses will tend to find the source at a greater

distance.

Figure 1 depicts a detector’s data stream, processed as 1-second measurements that are subsequently

analyzed in 8-second rolling windows for radionuclide IDs.

Figure 1 Rolling-Window Analysis of Detector Data Stream at 1sec intervals.

Figure 2 illustrates the effects of the vehicle speed, source-to-detector distance, and detector group FOV

for a survey conducted at 5 mph (~7 ft/s) and a “detector group” FOV of 120 degrees.

Detective-Remote® is factory-configured to use 8-second and 30-second data integrators, a solid, general

purpose pair of integrators. However, the Setup and Options program lets you choose the number and

duration of data integrators for your detection scenario (see Section 4.1.1).


22

IMPORTANT

Changing integration times can dramatically reduce the system’s ability to locate radionuclides.

Figure 2 Speed, Source Distance(s), and Detector Group FOV Interactions in Mobile Searches.

Integrator intervals should reflect the amount of time the source is in each detector’s field of view (FOV)

and in the entire array’s FOV. Thus, a vertical stack of detectors might use shorter integration times than a

horizontal array.

Array FOV should be determined on the basis of your system’s geometry relative to the anticipated

location of the radioactive source and multiple integrators should be used when you anticipate a wide

range of source-to- detector distances.

Note: The number of detector groups multiplied by the number of data integrators determines the number

of passes the analysis engine must make each second. More detectors and multiple data integration times

increase the amount of computer power and time to process data.

To avoid throughput issues, we strongly recommend not more than four data integrator times. The lowest

useful integrator interval is 2 seconds.

The 2 second integrator is likely only practical for a controlled-speed portal monitor configuration with a

vertical array of detectors.

Modeling the expected sources, distances, vehicle speed, shielding, collimation, and other factors will

help determine the appropriate set of data integrators for a fixed number and type of detectors to provide

the best results for your application.

Contact your ORTEC® Representative or ORTEC

® Technical Services Group for more information.

4.1.1 Changing Data Integrators Can Improve Source Resolution

What happens when two sources of the same kind are so closely spaced that both are detected within one

data integration period?

In the upper part of Figure 3, an 8-second data integrator is in use, and the two sources generate a single

ID event in rolling windows 18–34.


23

The lower part of the figure shows that a 4-second data integrator detects the two sources separately, in

rolling windows 18–22 and 26–30.

NOTE: If the second ID occurs less than 4 seconds after the end of the first ID, Detective-Remote® treats

it as a continuation of the first ID.

Stated another way; in this instance while using an 8- second integration window if a second source

passes into the FOV within 8 seconds, Detective-Remote® treats the second source as a continuation of

the first ID. Changing the integration window to 4 seconds, and keeping source passing through 5- 8

seconds after the first source passes, Detective-Remote® will see both sources.

This diagram is intended to illustrate the kind of effect that changing a data integrator may have on source

detection. In the field, the effects of changing data integrators may not be this predictable and must be

explored with scenario modeling!


24

Figure 3 Changing Data Integration Time May Help Resolve Closely Spaced Sources.


25

4.1.2 Rolling-Window Analysis vs. Data Display in Detective-Remote®

For simplicity, let us say Detective-Remote® typically identifies a radiation source 0.75 second to 1.0

second after the source enters a detector group’s FOV8. This means that as a detector group moves into

view of a source, the source ID will be posted in the last 1 second of the oldest “live” rolling window (for

an 8-second integrator that would be the window that started 7 seconds ago), and that ID will persist for

one integration period (8 seconds) after the source exits the detector group’s FOV.

This is illustrated in Figure 4, which shows approximately 22 seconds of detector data. Data stream

measurements 9 through 31 are shown here. They are analyzed in fifteen 8-second rolling windows.

During this time, the detector “sees” a threat source for approximately 2 seconds, beginning at the end of

rolling window19. Identification occurs in rolling window 20 and ends shortly after the start of rolling

window 28. Rolling window 29 does not “see” the source. Thus a 2-second radiation exposure affects

nine 8-second rolling windows and nine measurements.

Note how the various aspects of this ID event are reflected in the User Interface program’s data displays.

• Measurements tab — When you start a search, the Measurements tab begins tracking the1-second

data stream measurements. Measurements that do not generate IDs have a white background. You

can see that when the threat ID “Neutrons on Fe” is posted in rolling window, measurement 20

(see Figure 4), the display background turns red and the threat ID is posted. The red background

and threat ID name persist through Measurement 28. Measurement 29 (not shown) will have a

white background.

• Events tab — The Events tab registers an ID event for the threat Neutrons on Fe. Note the red

background; the event duration of 2.0 seconds; and the event date and time, which match the date

and time of Measurement 20.

• Charts tab — The Signal and Threat Index data scroll from right to left, so the oldest data are on

the left. The two charts show 22 data stream measurements, from measurements 9 through 31;

with the identification of a threat beginning in measurement 20 and ending in measurement 28.

The low amplitude of the Signal Index indicates that the radiation source was relatively weak;

however, the very high Threat Index value indicates the analysis engine identified the threat at

very high confidence. Both charts registered the 2-second radiation exposure across nine

measurements, after which both indexes dropped to zero.

• Alarms tab —Not shown here, the entries on this tab drop off after (1) they are acknowledged and

(2) the data integrators no longer “see” the ID event. In this case, the alarm entry was displayed

for nine measurements.

8 The brief period from the detector’s first “view” of a source until the analysis engine identifies it and posts an ID

event is affected by numerous factors, including source strength, vehicle speed, data integrator times, source to

detector distance, the number and type of detectors in a group, their horizontal and vertical spacing, hardware and

software timing and throughput rates and counting statistics.


26

Figure 4 ID Event and Data Display in Detective-Remote®.


27

4.1.3 Data Display on the Map Tab

An ID event posts simultaneously on all tabs as soon as the confidence level reaches a threshold value

specific for the detected radionuclide (i.e., different radionuclides post ID events at different confidence

levels; this is internal to the analysis engine). Depending on source strength and location, this “alarm”

may display only a fraction of a second after the source enters the detector’s FOV. Then, because of the

wide FOV, the source may remain in the detector’s view for several seconds after the ID event is posted,

during which time the confidence level for the ID will likely increase. As a result, the point at which the

analysis engine calculates the ID with highest confidence may occur after you have passed the source

(this effect will be more exaggerated with longer data integration times).

The Map tab tracks this change in confidence level. It posts a triangular ID Event icon ( ) on the map at

the same time the other tabs respond. Then, as long as the confidence level for the ID increases with each

subsequent measurement. The Event icon shifts in the direction of travel until the measurement with the

highest confidence level is calculated. The Event icon is then fixed at the site of that measurement9. Thus,

a time period of a few seconds may separate the posting of the alarm and the final position of the Event

icon on the Map tab. As a consequence, the Event icon’s position on the map may not mark the actual

source location. Keep this in mind during surveys and data review, and use all of the User Interface data

visualizations together to derive the best information about source location.

Example:

At a vehicle speed of 8 mph (12 ft/s), if the User Interface posts an ID event at the measurement Max cps

in Figure 5, then another 4–5 measurements elapse before the highest confidence level is calculated for

the ID (Max Q), the final position of the Event icon may be 50–60 feet beyond the actual source location.

Figure 5 Rolling-Window Analysis of Detector Data Stream.

9 To visualize this, observe the Measurements and Map tabs for a survey that includes an innocent or threat ID

event. On the Measurements tab, click each measurement for the event, and note how the confidence level (Q value)

changes from one to the next. Locate the entry with the highest Q and observe that it correlates with the position of

the ID Event icon on the Map tab.


28

Note: In the previous figure, the user has changed the default blue breadcrumb color and assigned a color

gradient based on increasing count rate. The color of the count-rate breadcrumbs peaks in intensity at

Max cps, a few measurements before the red ID Event icon and detection zone reach their final position at

Max Q. This is a good indication that the source is located west or northwest of the event icon.

The “Signal Index” on the “Charts” tab also provides information about source location. As you approach

a source, the Signal Index almost always increases before an ID event is posted. If the source is a threat

nuclide, the Threat Index begins to increase as well. Taken together with the timing of the alarm (and an

optional color gradient for the breadcrumbs), they should be helpful in pinpointing the source.

4.2 Software Overview

4.2.1 Software Components

Detective-Remote® has four software components.

Setup and Options

(Section 5)

This program identifies and governs the detectors to be used and their

optional distribution into detector groups, data analysis parameters,

background count time, and how alarms will be presented to users.

Always run Setup and Options with the other two components closed,

also close Setup and Options before starting the other two components.

System Startup

(Section 5)

Must be running to analyze detector data streams for IDs and alarms,

capture comments, record GPS coordinates for each measurement

(where GPS signal can be detected), and save survey and background

data to the survey database.

User Interface

(Chapter 6)

Controls only the display of the user interface screens and Review

mode data. Note that you can review existing surveys with just the User

Inter- face program. However, to collect data and monitor the detectors,

the Detective-Remote® System Startup program must also be running.

Sensor Portal Mapping

Platform

(Section 6.2.8 and Chapter

9)

Provides real-time, map-based monitoring and review of historic map

data. GeoServer open-source map tile server supplies worldwide street-

level map display, can optionally serve maps from almost any source,

and mediates caching of map data on the Detective-Remote® analysis

computer for use in the field/offline.


29

4.2.2 Operation Modes

There are four operating modes:

Mode Description

Idle

(Figure 26)

The User Interface “home screen.” Gamma count-rate, gamma dose- rate, and

(where applicable) neutron count-rate meters are active and displayed, but no data

are saved.

Survey

(Section 8)

Search — Manually timed survey intended primarily for mobile searches. The

system events, measurements, IDs, ID durations, alarms, strip

charts, and measurement-to-measurement detector status for a survey are saved in

a database, one database per survey.

Stand-in — Designed for stationary monitoring, performed to a user- defined

counting preset in the Setup and Options program. All survey data are saved in a

database, one database per survey.

Background

(Section 7)

Performed to a user-defined counting preset (1200 seconds minimum) in the Setup

and Options program. The frequency and duration of background measurements

will depend on your site operating procedures.

Review

(Section 8.2)

Select any survey and review the map and all events, measurements, IDs, alarms,

strip charts, and spectra.

4.3 How Survey Data Are Collected and Analyzed

As discussed in Section 4.1, each detector in the system transmits a continuous stream of spectrum data,

which the software measures approximately once per second. The data streams for all detectors in each

group are then combined for analysis. The combined group data stream is analyzed differently in the two

Survey modes.

4.3.1 Search Mode vs. Stand-In Mode

4.3.1.1 Search Mode

In the mobile Search mode, the combined data stream from each group is simultaneously analyzed with

(by default) rolling 8-second and 30-second integrations. This focuses the analysis on different distances

normal to the search system. The Setup and Options program lets you use a different number of

integrators and different durations (see Section 8).

4.3.1.2 Stand In Mode

Stationary Stand-In counts are designed to maximize the system’s ability to detect radiation. Instead of

the rolling-window analysis, each detector group’s combined data stream is analyzed cumulatively each

second for IDs and alarms. Thus, the survey contains analyses for the data periods from (t = 0 to t = 1 s),

from (t = 0 to t = 2 s), then (t = 0 to t = 3 s), and so on to the end of the measurement period.


30

4.3.2 Background Peak “Filtering”

In gamma spectroscopy, the concepts of “background measurement” and “background subtraction” may

have different meanings for different “types” of detectors. For high-purity germanium (HPGe) spectra,

peak-by-peak background subtraction is used.

Detective-Remote® uses HPGe detectors, but takes a slightly different approach to the background

measurement. The “Background” function determines, peak-by-peak, the net background count rate for

each of the 72 peaks listed in A.2. These peak energies are associated with innocent background NORM

(naturally occurring radioactive material) radionuclides.

The peak-specific, net background count rate is used as a filter with each survey spectrum before it is

analyzed for alarms. The “filtering” of these 72 peaks minimizes the frequency of alarms for naturally

occurring radioisotopes to prevent them from becoming a “nuisance” when trying to focus on real threats.

This “filter” can be turned off as discussed in Section 5.3.3.4.

While performing a background with the instruments, the “Background routine” also aligns the 1460 keV

peak of K-40 in the factory-specified energy channel and pinpoints the gain stabilizer to the area around

that channel. This minimizes gain stabilization errors.

See Chapter 7 for instructions on how to perform instrument background measurements.

IMPORTANT:

Although the Detective®-200 and other standalone Detective

® instruments have their own background

measurement capability, all background measurements for the Detective-Remote® System must be

performed in the Detective-Remote® user interface program.

Backgrounds performed in the Detective®’s standalone program are not used by Detective-Remote

®.


31

4.3.3 LCX (Low-Confidence Expert) Identification Mode

Detective-Remote® has two radionuclide identification modes:

• Standard — This posts only threat and innocent IDs made at a high confidence level (this

confidence level is also referred to as the Q value). With exceptions as noted, this manual

discusses only the standard identification mode.

• LCX — LCX mode displays suspected threat alarms and IDs at a lower confidence level than the

standard ID mode. The confidence level is user-selected and can be set between 50–90%. This

results in more hits on suspected threat nuclides. Although detection is arguably improved in

LCX mode, the false alarm rate will increase to a level which may be unsuitable for many

applications. For example, at a 70% setting, the Detective-Remote® software will issue

approximately two false suspect threat alarms every hour in LCX mode. Therefore, it is

recommended that LCX mode be used only by an experienced spectroscopist who can monitor

and verify the data. In LCX mode, Suspect ID measurements, events, Signal and Threat Index

peaks will have a yellow background. See AppendixA.1 for the suspect messages exclusive to

LCX mode.

To switch between Standard and LCX modes, go to the “Acquisition” tab in the Setup and Options

Program (for more information see Section 5.3.3).


32

4.4 Alarms and Alarm Handling

There are four alarm types in Detective-Remote®, each with a distinctive background color and unique

audio tone or synthetic voice signal.

Threat (red)

Indicates a high-confidence ID of a threat radionuclide.

The threat alarm tone sounds, the bottom button bar and Acknowledge button turn red,

the back ground for alarm-related events and measurements is red, and red peaks are

displayed on the Signal Index and Threat Index graphs.

On the Map tab, the detection event is marked with a red triangle.

Suspect (yellow; LCX

mode only)

Suspect alarms are generated only in the LCX mode, which is intended for use only by

experienced spectroscopists (Section 4.3.3).

The suspect alarm signal sounds, the bottom button bar and Acknowledge button turn

yellow, the background for alarm- related events and measurements is yellow, and

yellow peaks are displayed on the Signal Index and Threat Index graphs. On the Map

tab, the detection event is marked with a red triangle.

LCX mode has an Elevated radiation or beta ID that indicates the gamma count rate is

higher than can be accounted for based on the peaks in the radionuclide library. The

implication is that either an unexpected nuclide or a beta emitter is present (beta emitters

typically producing counts over a broad range of energies). Move closer to the source

and count longer to determine the nature of the suspect item

Innocent (green)

Indicates a high-confidence ID of an innocent radionuclide.

The innocent alarm signal sounds, the bottom button bar and “Acknowledge” button

turn green, the background for alarm-related events and measurements are green, and

green peaks are displayed on the Signal Index and Threat Index graphs.


33

System Error (amber)

Indicates non-radiation errors, such as detector, software, or network problems.

The error alarm signal sounds, the bottom button bar and ”acknowledge” button turn

amber, and the background for alarm-related events and measurements is amber.

On the Detectors tab, the detector status indicator may display one or more system error

messages on an amber background. If the error affects the detector subsystem’s

readiness, the detector status indicator changes to Status: Not Ready.

(See also Figure 38)

Each time an ID is posted:

• Any number or combination of alarm types can occur simultaneously. When multiple alarms are

generated, they are presented highest-priority alarms first (e.g., reds, yellows, greens, ambers).

• The Alarms tab shows active alarm entries. Alarm background mirrors the alarm color. Even after

acknowledgment, they persist until the identified radionuclide is no longer detected by any of the

system’s detector groups.

• The bottom of the screen changes color according to the current highest-priority alarm. The color

persists until the alarm drops off the Alarms tab. At the same time, the bottom right of the screen

displays an Acknowledge button listing the ID or error and mirroring the alarm color. The

Acknowledge button remains displayed until acknowledged, even if you exit and restart the User

Interface program. Event notification can instead be displayed in a color-coded pop-up box that

has an Acknowledge button and comment field. See Figure 13.

• Click Acknowledge. This logs the alarm as acknowledged on the Events and Alarms tabs. If

using the ID pop-up box (Section 5.3.2), you can acknowledge alarms by clicking in either the

pop-up box or the Acknowledge button.

• The ID or error is noted on the Events tab as an event for this survey, and the event background

mirrors the alarm color.

Until the identified radionuclide is no longer detected by any of the detector groups, the “Measurements”

tab posts once-per-second measurement entries colored according to the highest- priority alarm

determined for that time slice. (As discussed in Section 6.2.2, clicking a measurement displays a complete

list of all alarms and IDs for that time slice.)


34

4.4.1 Acknowledging an Alarm Does Not Clear the Condition That Caused It

The radiation condition causing the alarm must be considered present until the detail box for new

measurements no longer show it to be present. Once the alarm for a particular ID is acknowledged, the

alarm indicator does not reactivate for that ID event. However, if the source is moved away from the

detector(s) until no longer detected, then reintroduced, a “new” ID of the same source could generate

another alarm.

4.4.2 Important Note about False Alarms

Because the Detective-Remote® software is designed to operate at very sensitive detection thresholds, a

Threat alarm may occur from time to time when no threat nuclide is present (typically once every several

hours), depending on the ambient background at your site. Acknowledge the alarm(s) and see if it recurs

while measuring the same object. If it does not recur, there is typically no need to investigate further

(however, your response will depend on your CONOPS). If it does recur for the same object, refer to your

site operation procedures to determine the action to be taken.

4.5 Data Collection, Storage, and Management

In the Search and Stand-In modes, the Detective-Remote® system surveys the space within the detectors’

FOV for the presence of the radionuclides in the ID library. All spectroscopic data, location data, and

analysis results from the survey are saved in a Microsoft SQL Server database, one database file per

survey. The maximum database size is 10 GB10

. Each survey database records the following:

• Raw spectrum data from each detector, collected approximately once per second.

• The list of the IDs found, along with their confidence values and the detector group(s) and data

integrator(s) that produced each ID.

• The date and time associated with each 1-second data measurement.

• The Signal Index and Threat Index values (see page 54).

• The GPS coordinates associated with the data, where GPS signal can be detected.

• All data necessary to recreate the map interface for all survey measurements and events.

10 To exceed this file size, you would have to perform a continuous, multi-week survey!


35

Survey names are assigned to the Survey Database by the system and displayed in the detail box for

the survey when you click the “Start Search” or “End Search” event for a particular survey (see

Figure 6). Survey names cannot be modified, the Review mode lists surveys by date and time, as well as

an optional survey Description which the operator may enter (see Figure 60). We suggest assigning

informative survey description that, in addition to the date and time, will help you locate the

desired survey(s) for review and optionally annotate the contents.

Figure 6 Survey Database Name Displayed in the “Search Started” and “Search Ended” Event Boxes.

4.5.1 Data Backup and Management

• Appendix C tells how to export (back up) and import (restore) Detective-Remote® survey

database files using SQL Server Management Studio.

• Database Backup —Exporting your surveys is the surest way to produce data backups that can be

easily restored.

NOTE: While a third-party archival program can be used to copy the analysis computer’s entire hard

drive, database recovery from this type of backup is difficult and time-consuming. For more information

on backing up and restoring large numbers of SQL Server databases, see the Microsoft website11

.

Portable Survey Data — Exported surveys can be imported and reviewed by anyone with the Detective-

Remote® suite of software components. Surveys cannot be imported from a newer version of Detective-

Remote®. Survey files created with an older version of Detective-Remote

® are updated by the User

Interface program the first time you open them in Review mode.

11 There are also third-party SQL Server database backup tools, but ORTEC

® has not tested any so caution is

advised.


36

IMPORTANT

Other than creating backup sets and archiving your hard drive, do not make any changes to the Detective-

Remote® database contents. Doing so may cause loss of data.

For more information, contact your ORTEC® Representative or our Technical Support Group.

4.6 System Cautions and Operating Limitations

• When positioning Detective® instrumentss, securing them with tie-down straps, etc., take care not

to bump the touchscreen and change settings, especially the “wireless-or-USB” radio buttons.

• Be sure to observe the cautions and limitations with respect to operating conditions, for each of

the components in the system. See the hardware manual for details and restrictions for any

Detector system.

• The coolers and detectors are shock-sensitive. Consult the hardware manual for your identifier

type for handling recommendations.

• Protect the system components from prolonged or heavy rainfall and from immersion. On

instruments with integral dust caps on the data and power ports, keep all unused connectors

capped.

• You can turn a Detective®’s cooler off for a brief period (e.g., 10–20 minutes) without

significantly warming the detector. As soon as the cooler is restarted, the computer touchscreen

typically shows the word “Ready” within a few seconds. The cooler can be restarted at any time

without harming the detector crystal, regardless of detector crystal temperature.

• The mechanical coolers for the Detective-Remote® detector subsystems are designed for years of

continuous operation. We strongly recommend that you leave them on and the detectors fully

cooled except during shipping, some storage conditions 12

or maintenance. However, the computer

and network hardware can be turned off between surveys, if you wish. The unit can be shipped as

soon as the cooler is turned off. There is no need to wait until the detector warms up. Commercial

transport regulations require that the internal battery be sealed in its compartment during

shipping. Follow the shipping instructions in the hardware manual.

12 Caution: read the hardware owner’s manual before storing ORTEC

® Detective® identifiers, in a warm condition,

for periods longer than a month. Periodic startup and operation for 1-2 days is recommended on a monthly basis.

5 STARTUP AND SETUP DETAILS

This chapter provides the system startup details for the steps in the Chapter 3 quick-start guide.

Preparing the Detective-Remote® system for field use requires:

• Starting the detectors and cooling them to operating temperature.

• Starting the Detective-Remote® computer(s).

• Establishing wireless or wired USB communication between the computer(s) and detectors.

• Configuring system parameters such as the number and composition of detector groups, default

background count time, and alarm notification options.

• Pre-caching (seeding) the map tiles for the survey region.

Once these steps are completed, you’re ready perform a background measurement for the survey site

(Chapter 7), then begin radiation monitoring (Chapter 8).

NOTE: Except where noted, these instructions are written for the one-computer configuration. If

your system uses two computers, all instructions for the User Interface program are run on the user

interface computer; all instructions for the Setup and Options and Detective-Remote® System Startup

programs are run on the analysis computer; and the user interface computer must be connected to the

analysis computer’s WLAN.

5.1 Start Up and Cool the Detectors

1) Connect each identifier or interchangeable detector module to an external power source as

described in the unit’s hardware manual. Be sure to note all of the hardware operating conditions

and cautions.

2) Power up the Detective®-200's computer by pressing the On/Off button at the bottom-right of the

touchscreen bezel. The unit will boot up (which may take several minutes) then auto-start the

Mobile MCB Server application, which will take another 20–30 seconds to initialize (during

which time the Windows Desktop and other screens will briefly be displayed).

3) When startup is complete, the touchscreen should appear as shown in Figure 7. For wireless

systems, the Wireless/ActiveSync radio button on this screen must be marked. For wired systems,

the USB Control button must be marked.

IMPORTANT: Do not change the factory-set communication mode. This is particularly important if you

are using the wireless setting. Changing to the USB mode then switching back to wireless mode may

cause the Windows Mobile operating system to reset certain networking characteristics such as the IP

address. Any changed settings will need to be restored before the system will function properly.

See Appendix B.

4) Tap “Exit to Windows” to exit to the orange ORTEC® Launcher interface (Figure 8). Confirm the

Mobile MCB Server box is marked to ensure the system self-recovers after power loss.

Figure 8 The ORTEC® Launcher Screen.

5) From the orange “Launcher” screen, tap the “Detective®” button. This will take you to the

Detective® “Home Screen”

6) The home screen is labeled “Survey Mode” ( shown in Figure 9). If the Status indicator on the

display reads Cooler Off, start the cooler as follows. If the cooler is On, skip to the next step.


39

Figure 9 The Detective® Software Home Screen.

7) Referring to the Detective®-200's hardware manual, tap the “Advanced” button to display the first

“Advanced Setup” menu page and tap the button “Turn Cooler ON”. Within a few seconds, the

cooler will start, although you may or may not be able to hear or feel the cooler running. When

you tap the Back button to return to the Detective® application’s “Survey Mode” screen, the

status indicator will read Status: Cooling.

8) There are two ways to monitor detector and hardware status:

A) On the Detective ®’s screen. To do the latter, tap Advanced, Status. Until the detector has

cooled and the HV has automatically turned on, Detector Temp, Cold Tip Temp, and HV

Volt will read ERR, when they have reached operating temperature, they will switch to

OK.

B) On the Detective-Remote® User Interface program’s “Detector Health” tab (6.2.5). On

two-computer systems, both computers must be running and connected to the analysis

computer’s ad hoc network. See the next section for computer startup instructions.

Notes:

• A warm Detective®-200 typically requires < 14 hours to cool to operating temperature, but may

take longer.

• When the detector reaches operating temperature, the bias voltage will automatically turn on.

During the cool down period, ignore any status indicators on the Detective-Remote® “Idle”

screen.

• As noted in the Detective®-200 Operator’s hardware manual, the internal battery will not charge

until the detector has reached operating temperature. After that, the battery will typically reach

full charge in 3–4 hours.

All background measurements and other functions are handled from the computer’s Detective-Remote®

user interface.


40

9) Exit the Detective® application by tapping Advanced, Next>>, Next>>, and Exit. This will return

you to the orange Launcher screen. Tap Mobile MCB Server to reopen the screen shown in

Figure 7, and wait 20–30 seconds for it to fully initialize.

5.2 Start the Computer(s) and Network Hardware

1) Power up the analysis computer and log into Windows on the Detective-Remote® account

13. The

factory default Windows password for this account is (all uppercase, no parenthesis) “ORTEC”.

Key system data including the computer login, password, ad hoc network name, network security,

network security key, and IP addressing are factory pre-configured and should only be changed in

consultation with your ORTEC® Representative or our Technical Services Group.

2) For wired systems, you need only login on the computer(s). The wired network icon ( ) will be

displayed in the system tray.

3) For wireless systems, the analysis computer does not automatically reconnect to the ad hoc

wireless network after reboot so you must manually connect it. On the analysis computer, click

the WIFI signal strength icon in the lower-right system tray, then click the network named for the

analysis computer’s serial number. Figure 10 illustrates the appearance of the system tray as you

connect to the network.

NOTE: Note that you must also manually reconnect to the network after restarting the computer(s) or if

all detectors are disconnected from the network.

4) For the two-computer system, start up the user interface computer, log into Windows on the

Detective Remote account, and connect to the analysis computer’s ad hoc network.

13 To run any of the Detective®-Remote applications from a user-defined account (as distinguished from the factory-

defined account), Windows will ask for the Detective®-Remote install disk. If you cancel the install prompt, none of

the program shortcuts will work. Completing the wizard will fix the shortcuts.


41

Figure 10 Click the WIFI Icon and Connect to the Computer’s Wireless Network.

5.2.1 Ready to Run Setup and Options Program

1) When the detectors reach operating temperature, the bias voltage will automatically turn on and

self-adjust to the proper setting.

2) If the detectors are communicating with the computer(s), the Detectors and Detector Health tabs

in the User Interface program will display the detector status information as the detectors

continue cooling. When the detectors are ready to use, the detector status indicators on the

Detectors tab will change to Idle status. Acknowledge any errors which may occur.

3) While the detector subsystems are cooling, you can open and run the Setup and Options program

to check the system configuration. Just be sure to close DR User Interface and DR Startup before

opening Setup and Options.


42

5.3 Run the Setup and Options Program

The Setup and Options program governs system configuration settings including the detectors to be used;

if and how they will be distributed into detector groups; the number and duration of data integrators; how

alarms will be presented to the user; and other global parameters.

NOTE: The Setup and Options program affects the Detective-Remote® system’s core functionality and

should only be modified by knowledgeable users. The User Interface and Detective-Remote® System

Startup programs must be closed when this program is running; otherwise, they will not register any

changes you make on this page.

The default settings for factory-configured systems will typically not require changes, so run Setup and

Options only in the following cases:

• On initial system startup after purchase of a new system.

• To modify data integration times, detector-group assignments, or reach back settings.

• To add a new detector module to the system and assign it to one or more detector groups.

• After upgrading the Detective-Remote® software.

• To acknowledge a significant number of outstanding alarms from the last work session

(numerous hardware alarms may accumulate hardware if you use the computer[s] without the

detectors, e.g., for survey review).

The System Startup program auto-starts each time the computer is rebooted, therefore, the first step is to

close it. Click the DR icon, , in the system tray, then click the upper-right corner (×) on its popup

screen. Shutdown takes about 5 seconds. (The Detective Remote User Interface program should already

be closed, if not, close it.)

Start Setup and Options by entering setup in the “Search programs and files” box on the Windows Start

panel and clicking the Setup and Options search result; or open the going to the Windows Start menu and

open the file “ORTEC® Detective-Remote

®”, then click on Setup and Options.

On first use of a new system, check the settings on the tabs as described in the following sections. If

adding a new detector module to an existing system, you need visit only the Startup and Detector Groups

tabs.

You will then be ready to exit the Setup and Options program, click the Close [×] box, and start the

“Detective-Remote® System Startup” and “Detective-Remote

® User Interface” programs.


43

5.3.1 Server Tab

Figure 11 shows the Server tab.

IMPORTANT:

The System Number, SQL Server Address, SQL Server User ID, and SQL Server User Password entries

on this tab are pre-set during system installation. Any changes to these settings will prevent the system

from collecting, analyzing, and storing data.

Contact your ORTEC® Representative or our Technical Services Group if you have any questions about

the information in these fields.

The Check for upgrade and/or repair button should only be used to activate a new software upgrade or to

acknowledge all outstanding alarms from preceding work sessions. The latter can be useful if, for

instance, you have generated numerous hardware alarms by using the computer(s) without the detectors

connected (for example, to review previous surveys)14

.

Figure 11 All Components Found, No Errors; System Ready for Operation.

14 Note that ORTEC

® service personnel may also instruct you to click this button as part of resolving system

problems


44

5.3.2 Display Tab

The check boxes on this tab (Figure 12) give you options for displaying and annunciating ID alarms;

displaying neutron count data; and hiding the Threat Index.

Figure 12 The Display Tab.

The Show popup on source identification option opens a pop-up box (Figure 13) that parallels the

operation of the Acknowledge button (see Secs. 5.1.1.2 and 5.1.1.3).

• The box is color-coded according to threat level (red, yellow [LCX mode only], green, amber).

• The pop-ups persist until acknowledged.

• If multiple alarms are generated at one time, they are presented highest priority first.

• Before clicking the Acknowledge button in this box or on the button bar, you may enter a

Comment for this event that will be recorded in the Events log.

NOTE: If multiple alarms are generated and you enter a comment in a pop-up box, all subsequent pop-

up boxes for this alarm event will display the same comment. Edit or delete it as needed before

acknowledging. The auto-text is cleared at the end of the alarm event (so the comment field will be blank

the next time a pop-up box opens).


45

Figure 13 Pop-Up System Error and Innocent ID Alarms.

5.3.2.1 Synthetic Speech Alarm Annunciator

Marking the Use speech output checkbox changes the audio signal alarms for the four threat types to

alarms annunciated with the currently selected Windows synthetic speech “voice.”

5.3.2.2 Show Neutron Data

This is useful only if one or more of your detectors are equipped with a neutron detector. This adds a

“virtual strip chart” to the Charts tab in the User Interface program.

5.3.2.3 Show Threat Index

Unmarking this box hides the Threat Index virtual strip chart (also see Section 6.2.6) so that the Charts

tab displays only the Signal Index.


46

5.3.3 Acquisition Tab

The settings on this tab (Figure 14) determine:

• the ID mode (high- or lower-confidence);

• the maximum time between background measurements;

• the default count times for Background measurements and Stand-In surveys

• whether to suppress or display IDs of NORM (naturally occurring radioactive materials).

Figure 14 The Acquisition Tab.


47

5.3.3.1 LCX Mode

Low-Confidence Expert Mode is discussed in Section 4.3.3.

To switch to LCX mode, mark the checkbox and set the slider to the desired confidence level. The data

point detail box for each Event displays the LCX mode (disabled/enabled) for the survey and, if LCX

mode is enabled, the % of Normal Q-Value Threshold setting (Figure 15). The background color

associated with suspect IDs is yellow.

Figure 15 LCX Mode and Setting in the Data Point Detail Box on the Events Tab.

5.3.3.2 Background Count Preset and Expiration

We recommend a count time of at least 30 minutes, 1800 Seconds and the system minimum background

count length is 1200 seconds. You may change this preset to any value > / = 1200 seconds (20 minutes).

If you end the background count early, before the minimum 1200 seconds, the “new” background is not

saved and the previous background files will be used.

If you end the background count early and 1200 seconds has transpired the new background will replace

the previous and will immediately be used by the software.

The Background expiration is the number of days between required background measurements. If this

period is exceeded, all detectors will display expired-background error messages. A new background

count must be performed before radiation surveys can be performed.

5.3.3.3 Count Preset for Stand-In Surveys

Your site operation procedures or your current circumstances will dictate the count length to collect a

spectrum for reach back. In Detective-Remote® this would be a “Stand In” Survey. On the Acquisition tab

shown in Figure 14, you set the default preset count period. This preset can be changed as needed. Note:

Users can stop a Stand-In survey before the “preset” count time expires, or extend it in increments of 30

seconds as dictated by the circumstances.

5.3.3.4 “Filter” Background NORM IDs

The table in Section A.2 lists the gamma peaks which the Detective-Remote® analysis engine treats as

innocent, NORM background radiation. As discussed in Section 4.3.2, the “Background” function

performs a peak-by- peak analysis to determine the net background count rate for each of these peaks. If

the Background checkbox is marked, the net background count rate for each of the NORM peaks is

subtracted from the survey spectrum before it is analyzed for alarms. This background “filtration” step

significantly reduces the frequency of nuisance alarms. If you unmark the checkbox, (Figure 17) the

NORM peaks are analyzed for alarms without the “filtration” step.

5.3.4 Alarms Tab

The Alarms tab (Figure 17) has a survey vehicle speed alarm, in miles per hour, and individual control

over NORM Identifications, Innocent identifications, Suspect Identifications, and Threat identifications.


48

5.3.4.1 Exceeding Speed Alarm

The speed alarm provides an option for users to set a speed alarm for performing surveys. This is very

effective in implementing minimum detectible levels of threats during a survey scan.

If the vehicle exceeds the Speed Limit, the Acknowledge button and the lower edge of the screen will

change to amber, and a system health error will be posted to the Events and Alarms tabs. Slow the vehicle

and acknowledge the alarm.

Figure 16 Acknowledge Speed Alarm.

5.3.4.2 Alarm on NORM Identifications

The NORM alarm provides an option for users to set receive an alarm when NORM isotope

concentrations have exceeded background limits. This is very effective in adjudication of secondary or

separate instrument alarms from handhelds, backpacks etc.

5.3.4.3 Alarm on Innocent Identifications other than NORM

The innocent alarm provides an option for users to control the alarms for innocent identification while

performing surveys. This is very effective in reducing the number of alarms displayed that are a function

of testing or when operating in a location with known innocent sources of radiation.

5.3.4.4 Alarm on Suspect Identifications other than NORM

The suspect alarm provides an option for users to control the alarms for suspect identifications while


of testing.

5.3.4.5 Alarm on Threat Identifications other than NORM

The threat alarm provides an option for users to control the alarms for threat identifications while


of testing.

50

5.3.5 Startup Tab

Before setting up detector groups on the Detector Groups tab, use this screen (Figure 18) to choose which

Detectors will be “active” in your detector group(s). Activate them by clicking their checkboxes. These

settings can be changed at any time.

If a detector is highlighted with red text, it has been part of your Detective-Remote® system sometime in

the past but is currently not on the MCB Configuration list. If you have temporarily disconnected one or

more detectors, ignore the red highlighting and select the detectors (highlighted or not) you intend to use.

IMPORTANT

The settings in the Programs section of this tab are factory pre-configured for your one- or two-computer

system. Do not change these settings without consulting your ORTEC® Representative. Changing the

GPS Serial Port Number will inactivate the GPS causing a loss of GPS coordinates.

Figure 18 Startup Tab — Select Detectors.


51

5.3.5.1 Troubleshooting System Configuration Errors

If one or more of the Detective®s in your system are not listed in the Detectors section of this screen, or if

one or more entries are displayed in red:

• Make sure the “missing” Detective®s are showing the correct connection method either:

1) wireless / active sync or

2) USB Control, on the Mobile MCB Server screen (Figure 7).

• Check to make sure the GPS is connected and the symbol for the Franson GPS Gate is visible on

the Laptop Windows taskbar and is displayed as “green” not “red”.

• With the cursor hover above the DR symbol to see whether either the GPS or Detective®

instruments has a yellow triangle.

• For wired USB systems, make sure the cables for “missing” Detective®s are connected correctly,

and are not defective.

• For wireless systems, the Detective® Mobile MCB Server display shows a count for instruments

and wireless connections. i.e. Instruments: X Connections: X, be sure that it has a 1 under

connections. If it displays Connections: 0 the Detective® is not communicating with the laptop.

• On the computer, if the Windows Taskbar does not show a “wireless symbol but rather a red

antennae, locate and turn on the wireless switch.

• Click on the “wireless” symbol, find the computer name click on it and “connect” if the status is

not “Connected”. Wait 20 - 30 seconds to see if communication is established.

• To check wireless communication “setup” on the “missing” instrument (s):

o On the Detective®, from Mobile MCB Server tap “Exit”, when prompted answer “yes” to

“exit program”. The display will return to the orange “ORTEC® Launcher” interface

(Figure 8),

o From the “Launcher” tap “exit” and “exit to Windows” returning to “Windows Mobile”

o Beneath the START button, look for the blue wireless antennae symbol.

o Next to the symbol it should list Wi-Fi: DR-[computer S/N] or (WLAN: ON).

o If this is displayed, you should be OK. Go to Start > Launcher to restart the Detective®

Mobile MCB server program. (alternately you may reboot by holding the power button

through the 5 second countdown to initiate a reboot )

o The Mobile MCB Server should auto-start directly to the screen shown in Figure 7. If it

goes to “Launcher” be sure the checkbox beside the Mobile MCB Server button is

checked then tap the button.

o Confirm the display shows the correct connection method. (wireless / active sync)

o Return to the computer(s), reconnect to the LAN as discussed in Section 5.2.


52

o Repeat this process for each Detective® not communicating with DR.

• If one or more Detective®s still cannot be found, but they indicate that they are connected to the

DR computer Wi-Fi or LAN

o Close DR,

o From the shortcut on the Windows Desktop double-click the “MCB add new” icon.

• The resulting dialog (which is discussed in detail in the accompanying CONNECTIONS and

MAESTRO user documentation) should display all of the Detective®s in your system.

• If the units are identified in MCB add new”, close this window and return to DR “Setup and

Options” program (discussed in Sec 4.2.1), select the “Startup” tab, confirm that all detectors are

now displayed, and check the box for the instruments to be used.

• If any Detective® Units are still missing, go to Section 10 to continue troubleshooting.


53

5.3.6 Reach-back Tab

The Reach-back option lets you specify an email Recipient to whom detection event information can be

sent from the User Interface program’s “Events” and “Reachback” tabs.

NOTE:

All reach-back communications include an N42.42-format .xml file containing the survey and background

spectra for each detector in the group that had the highest-confidence identification for the event.

As noted at the top of the tab, the default email sender is [email protected], an ORTEC®

account. To designate another sender, unmark the Use default settings checkbox and complete the fields

in the SMTP server settings and Sender settings sections of the screen.

Figure 19 The Reach-back Tab.

Enter a valid Recipient e-mail address and optional Recipient name. If you do not enter these fields, a

popup reminder will be displayed when you exit the Setup and Options program. Click No to ignore and

close.

To send more detailed information about an alarm event, in the “Setup and Options” tab mark the box for

“Show Reach-back Questionnaire” option. Instead of sending an automatic email, the form shown in

Figure 20 will open when you right-click an ID event and select it for Reach-back (Section 6.2.3.1); or


54

will be displayed on the Reach-back tab in the User Interface program. Complete the form and click

“Save” to transmit.

You can optionally develop your own reach-back questionnaire based on the default questionnaire,

Standard.quest.xml, located in \ORTEC \Detective-Remote in the current user account’s AppData folder.

To access the default questionnaire, open Windows File Explorer and enter the location %appdata%

Figure 20 Default Reach-back Questionnaire.


55

5.3.7 Detector Groups Tab

Use this screen (Figure 21) to optionally distribute your Detective®s into detector groups, to create new

detector groups, or to add a new detector module to one or more existing groups. The list of available

detectors is based on the instruments activated on the “Startup” tab. A red detector entry means the

detector has been incorporated into the system, but is not currently accessible (it may not be

communicating, it may not be checked on the startup page, it may have been removed, etc.).

The commands at the bottom of the screen let you add, rename, or remove a group; or listen to the

Microsoft synthetic speech module read out group names.

Expand each group to display the list of available detectors, mark the checkbox of the detectors you want

included in each group. Any detector may be included in multiple groups without limitation.

The changes you make to group names here, will display on the Status Graphics tab in Detective-

Remote® User Interface, (Section 5.3.9).

NOTE: Once a detector group is created, you may add or remove detectors at will. It is permissible to

completely restructure the type and number of detectors within the group or delete a group and start over.

You may find it useful to assign simple group names distinct with their location or area monitored (Left,

Right, Forward, Rear, etc.) and simply rearrange their list of detectors, as needed.

Figure 21 Adding a Detector Group.


56

5.3.8 Integration Times Tab

Figure 21 shows the Integration Times tab. Data integrators are discussed and illustrated in Section 4.1.

To add a new data integration time, enter the new value in the field at the bottom of the tab, then click

Add. To delete an existing integrator, click to highlight it then click Delete.

Figure 22 Add or Remove Data Integrators.


57

5.3.9 Status Graphics Tab

This is the setup screen for the detector group diagram on the User Interface Program’s Status tab (see

Figure 39). The Status Graphics Tab displays a default “vehicle” diagram and one rectangular icon

displaying the name of each detector group currently defined on the Detector Groups tab.

This is an optional feature intended to show which detector group(s) in the vehicle has made the highest-

confidence ID of a particular nuclide. In some cases, this information may help you locate a source.

However, using or not using the status graphic has no effect on detection, analysis, or IDs.

Before setup, the group icons are clustered in the upper-left corner of the tab. Simply click and drag the

box with a detector group name to the desired location on the diagram. You may reposition the group

icons at any time.

5.3.9.1 Using Custom Images

Two custom .JPG images (yacht view from above.jpg and SUV view from above.jpg) are supplied with

the Detective-Remote® software, and may be substituted for the default “vehicle” diagram. In addition,

you may substitute your own .JPG image. Different user accounts can optionally have different Status tab

images.

To change images:

If using your own image, copy it to the Windows clipboard. If using the supplied yacht or SUV images,

navigate to the C:\Program Files (x86)\ORTEC \Detective-Remote folder, and copy the desired image

onto the Windows clipboard.

In the address bar in Windows Explorer, enter the location %appdata%, Navigate to “\ORTEC\Detective

Remote” to paste the image file into that folder, and rename it to backgroundimage.jpg.

Close all Detective-Remote® applications. The next time you restart the Detective-Remote

® System

Startup and User Interface applications, the new image will be displayed in the Status tab.

The example Status tab images in Figure 23 depict the default “vehicle,” the supplied yacht image, and an

array of Detective®-200s for a stand-in or walk-through configuration.

Figure 23 Optionally Customize the Status Tab’s Detector Layout Diagram.

5.3.10 Manage Surveys Tab

Figure 24 Manage Surveys Tab.

Detailed instruction on exporting, deleting and importing surveys is found in Appendix C.


60

5.4 The Detective-Remote® System Startup Program

This application runs in the background and starts automatically each time you reboot the computer. It

should only be stopped if a system parameter must be changed in the Setup and Options program.

IMPORTANT:

If you accidentally close DR Startup program while performing a survey, data is no longer being acquired

or saved. Therefore, a gap of unrecorded data will exist in your database until the DR System Startup

program is restarted. Because of the data gap, the Survey analysis would likely be considered invalid so

the user will want to: End the current survey, launch DR System Startup program, then begin a new

survey.

To start the Detective-Remote® analysis-related programs: Go to Start > type “Detective

®” in the “Search

programs and files” box > click on “Detective-Remote System Startup” or the shortcut for the program

you want.

Alternately: Start > All Programs> Detective-Remote file > click on “System Startup”, “User Interface”

or “Setup and Options”.

To view the “DR System Startup” application; hover over or click on the DR icon ( ) located on the

Taskbar. This will display the screen shown in Figure 25. If the GPS antenna or one or more detector(s)

are not connected to the analysis computer, the DR icon will display a yellow caution indicator ( ).

Figure 25 The Detective-Remote® System Startup Tray Application.

The pop-up screen displays green, yellow, and red OK/caution/error status icons for the analysis-related

programs, GPS server, and system detectors. Roll over a yellow or red icon to see information about the

issue. Errors for the Analysis Program and DB Maintenance entries require consultation with our

Technical Services Group. GPS Server errors typically indicate that the GPS antenna is not connected to

the analysis computer. Any detector that is not connected to the analysis computer or has a current

hardware error will be marked with a red or yellow icon.


61

To shut down the Detective-Remote® System Startup application, click the upper-right corner (×) box.

Shutdown typically takes approximately 5 seconds.

5.5 Connect and Test the GPS Antenna

1) Connect the GPS antenna to the analysis computer (in two-computer configurations, if you

connect the GPS to the user interface computer, the analysis and mapping software will receive

no GPS input and the mapping feature will be automatically disabled). The tray icon for the

Franson GpsGate GPS server should change from red ( ) to yellow, indicating that the GPS

antenna is communicating with the server but does not have a satellite fix.

2) If the Franson GPSGate symbol does not change from red to yellow or green automatically, Close

Detective-Remote Startup, close Franson GPSGate, reopen Franson GPSGate and wait for the

symbol to turn yellow or green, then reopen “Detective Remote Startup”.

3) Start the User Interface program by Typing “user inter” in the “Search programs and files” box on

the Windows Start panel then selecting “User Interface”.

4) Take the computer and GPS antenna outside and wait for the system to acquire a GPS fix (this

will be displayed in the upper right corner of the User Interface screen). The Franson GpsGate

icon will change from yellow to green and the DR icon will no longer display the yellow caution

indicator.

If the FransonGps Gate icon remains red, see the troubleshooting steps in Section 10.3.

5) In Idle Mode, click the upper-right Show... button and select the Map tab to add it to the Idle

Mode view.

6) On the Map tab, verify that the map cursor is shown at the current GPS location.

5.6 Ready to Use the User Interface Program

The next step is to learn the User Interface program features and use, which are discussed in detail in the

next chapter.


62

6 USER INTERFACE PROGRAM

This chapter discusses the “Detective Remote User Interface” program features and use. Remember the

“Detective-Remote® System Startup” application must be running before the User Interface program will

function correctly.

To start the User Interface program:

• Windows Start> “Search programs and files” box enter “user inter” > select “User Interface”

or

• Windows Start > Program Files >Detective-Remote® file >select “User Interface”.

On first startup, the User Interface program opens in Idle mode, with the Detectors tab displayed in the

left pane and the Detector Health and Events tab on the right. On subsequent startups, it opens in the

mode which it was last closed. It is good practice to always close in the “Idle” mode.

Figure 26 shows a system with two detectors, both of which are connected, cooled, and ready for data

acquisition.

See Figure 38, for examples of status indicators for a detector in various states of readiness and operation.

NOTE: Until the detector subsystems are cooled to operating temperature, the status indicators will have

an amber “error” background, and will indicate the detectors are too warm. You may also see background

or full-width-half-maximum (FWHM) errors until you perform a background measurement.


63

Figure 26 User Interface Program — Idle Mode, Detectors Ready.

6.1 Main Screen Features

Figure 27 illustrates various screen features which may be selected for display. The Events History tab for

a survey in progress, displays alarms which have been generated for threat IDs Am-241 and Neutrons on

Fe, and innocent IDs Eu-152 and Unknown beta emitter.


64

Figure 27 User Interface Screen Features.

At initial startup, the Detectors, Detector Health, and Events tabs are displayed.


65

To open additional tabs, simply click the upper-right Show button and select from the available entries

(Figure 28). The list of available tabs changes with the operating mode, e.g., Search, Idle, etc. (see the

table on the next page).

In each mode (Idle, search, Stand In, Background, and Review) the tab arrangements are independent.

This allows you to choose which tabs to display, as well as how they are arranged and their size on the

6.1.1 Features Common to Multiple Tabs

6.1.1.1 Function Tabs

The function tabs shown in Figure 29, display real-time detector status and count-rate information;

current radionuclide IDs; a graphic representation of the detector group(s) contributing to the ID; a

continuous stream of all event and measurement information stored on the analysis computer during the

survey; and a continuous stream of “state of health” information for each detector.


66

These functions are discussed in greater detail in Section 6.

Figure 29 The Function Tabs.

Each mode (Idle, Search, Stand-In, Background, Review) has its own selection and arrangement of

default tabs. Add as many as you wish from the tab selection list (see Figure 28), and arrange them as

needed (Section 6.3).

When opening a new tab, it opens on top and to left of currently open tabs. If the user interface footprint

is too narrow to display the names of all the open tabs, those that not displayed are listed on a tab list.

Click the arrow icon to open the list, and select the tab you wish to display. (Figure 30).

Figure 30 Hidden Tabs Indicator.

The Detectors, Detector Health, and Alarms tabs always represent the live system state (never the review

survey state). The Measurements, Events, Map, Strip Charts, Status, Spectrum, and Reach-back tabs

always represent the current survey status (i.e., review in Review mode and live in Survey mode). The

Map tab has reduced function mode when in Idle mode.

6.1.1.2 Button Bar

These buttons control data acquisition and review. Different modes display different buttons. Figure 31

shows the button bar in Idle mode. It allows you to (create) a new mobile “Search”, stationary “Stand-In”

survey, start a “Background” count, “Review” an existing survey, or add a “Comment” to the Pop Up

Alarm and Event Log Figure 33 below (also see section 5.3.2.1).

Figure 31 Start Surveys, Backgrounds, and Reviews; and Add Comments to the Event Log.


67

6.1.1.3 Alarm Acknowledgement Button

Each time an alarm is generated, the ID is posted in the Acknowledge button in the bottom right corner of

the screen. Figure 32 shows the Acknowledge button for a nuclide ID and a detector “state-of-health”

error. If multiple alarms are posted at the same time, they are presented highest priority first. As you

acknowledge each one, it is removed from the bottom right of the screen.

If the “Show pop-up box on source identification” option is marked in the Setup and Options program,

(see section 5.3.2.1), a pop- up box opens at the same time the “Acknowledge button” is displayed

(Figure 33). If you wish to enter a comment tap the comment button, type a comment, then click

“Acknowledge” in the pop-up box or on the button bar to close both alarm windows.

Figure 32 Acknowledge Button.

Figure 33 Acknowledge the Pop-Up Alarm.


68

6.1.1.4 Data Point Detail Box

The Events and Measurements tabs have a data point detail box. This indicator:

• Tracks each new data point in the current search, updating about once per second

• Shows the information for a data point chosen from the Events or Measurements tab in either the

current survey or when reviewing a past survey.

In an active survey, this area updates in real-time unless you click a specific data point on one of the tabs.

Doing this stops real-time tracking and displays analysis or other event-related details for the selected

point. To resume real-time updates, click the Track Latest button at the upper right of the screen.

Figure 34 shows the data point detail box for the Measurements tab.

Figure 34 Data Point Detail Box — Measurements Tab.

The upper fields show the Point number, acquisition date and UTC time, GPS Location, and gamma and

optional neutron count rates. The lower section shows the IDs for this data point, their associated alarm

colors, the data integrator, and the detector or detector groups which generated each ID.

Figure 35 shows examples of “data point detail boxes” on the Events tab.

Figure 35 Data Point Detail Box — Events Tab.


69

6.1.1.5 EVENT-TYPE FILTER LIST available with the EVENTS, REACHBACK, AND

MEASUREMENTS TABS

The Events, Reach-back, and Measurements tabs have a filter list in the upper-right corner (Figure 36).

• Events tab — Filter for Information (non-alarm events), Operator Entries Only (Pop-up box

comments), system alarms, or radionuclide ID alarms, all alarms.

• Reachback tab — Filter for radionuclide ID alarms.

• Measurements tab — Filter for radionuclide ID measurements.

Figure 36 Event-Type Filter List for the Events, Reachback, and Measurements Tabs.

6.1.1.6 Data Synchronization Across Tabs

The Measurements, Charts and Status tabs are always synchronized with one another.

During a survey, single- or double-clicking an entry on the Measurements or Events tabs suspends real-

time tracking on all but the Map tab (which has its own Auto-Tracking feature; see Section 6.2.8.1).

While “suspended” the measurements and events are recorded and continue to accumulate, but you must

scroll down to see them. To return to “real-time” tracking, click the “Track Latest” button.

Double-clicking an ID event on the Events tab scrolls the Measurements tab to the highest-confidence

measurement for that ID; aligns the corresponding entries on the Status, Charts, and Spectrum tabs; and

repositions the map to select the ID event.

On the Map tab, double-clicking the popup window for an ID event performs the same synchronization as

double-clicking an ID event on the Events tab. Double-clicking in the pop-up for a measurement selects

the corresponding measurement on the Measurements tab, and aligns the corresponding entries on the

Status, Charts, and Spectrum tabs, but has no effect on the Events tab.


70

6.2 Function Tabs

6.2.1 Detectors Tab

This tab displays a status indicator for each detector in the system and displays real-time data including:

• Detector number and description.

• Operation mode of the system (idle, search, stand-in, background).

• Real-time gamma count rate, gamma dose rate, detector % dead time, and optional neutron count-

rate meters. These meters change from green to yellow to red as count and dose rates increase.

• A battery status indicator, and an “electrical plug” symbol if a detector is connected to external

power.

• System error/status messages (see Section 10.5 for troubleshooting errors). The type of system

error determines the color of the background. Note that as long as the indicator background is

white, the detector can be used for surveys. If the background is pink, the detector is out of

service.

Figure 37 is a “Detector Status Indicator” showing a detector in Idle Mode.

Figure 37 “1 DR-8066J” in Idle Mode.


71

The next figure, Figure 38, shows a variety “Detector Status Indicator” boxes displaying different count

rates. Also pictured are examples of comments which may be displayed on the bottom of the “Detector

Status Indicator”.

Figure 38 Detector Status Indicator and various “status” messages which may be displayed on the bottom of the status

indicator box.

6.2.1.1 Removing a Detector from the system

After a detector is added to the system, its status indicator will stay on the Detectors tab until you delete

it. Even when a detector has been removed from all detector groups and is no longer listed in the “Setup

and Options” program. The indicator for a disconnected detector is amber and says “Not

Communicating”. This is the same whether the detector is in a detector group and not communicating or

if it has been removed from the system but still shows up on the detector tab.

If you wish to delete it from the Detectors tab, place the cursor over the “Detector Status Indicator”, right-

click and choose “Delete”.

Should you accidentally delete the indicator for an active detector that is amber because it is not

communicating, it will automatically appear in the display when the detector resumes communication.


72

6.2.2 Measurements Tab

The Measurements tab (location shown on the left side in Figure 39) displays a chronological list of all

system measurements for the currently open survey, newest data point at the bottom. The order of

measurements displayed is the same whether this is a count in progress or an existing survey in Review

mode.

Figure 39 User Interface Program — Measurements and Status Tabs.

Measurements can be filtered by type; select a filter from the drop list symbol located directly above the

right corner of the measurement list (Section 6.1.1.5). Information about the currently selected

measurement in the list is displayed in the data point detail box. Also the associated point will be

displayed on the Charts tab, and on the Status tab.

In an active survey the measurements update in real-time until you click on an entry. Clicking an entry

suspends the real time aspect of the display while you view the point you have selected. To resume real-

time updates on this tab, click the upper-right Track Latest button and it will skip forward to the current

measurement.

Note that Figure 39 also shows the Status tab, which presents a depiction of the search vehicle. For the

selected measurement #28 in this figure, the highest-confidence-level ID (Q = 10.8) was made by the

detectors in Group 1 so the “Group 1” indicator is highlighted in the Status tab.


73

6.2.3 Events Tab

The Events tab (shown on the right side in Figure 40) displays a chronological list of all survey events,

newest entry at the bottom. The list includes: search start and end, stand-in start and end, background start

and end, IDs, alarms, system errors, and comments added via the pop-up ID alarm box.

Event information and the associated N42.42-format spectrum files can be sent from this tab via

“reachback” as discussed in Sec 5.2.3.1.

Figure 40 User Interface Program — Events Tab.

There are four (4) alarm states on the Events tab:

Alarm State Description of Alarm State

Active The alarm condition still exists and has not been acknowledged by an operator.

Unacknowledged The alarm condition has ended but an operator has not acknowledged the alarm.

Acknowledged The alarm condition has been acknowledged and still exists.

None (blank) The alarm has ended and has been acknowledged.

The events can be filtered by event type with the drop list at the top right corner above the tab (refer to

Section 6.1.1.5). During a survey, the event list updates in real-time until you click a particular event to

display its data point details. All real time updates to measurements, events and alarms are suspended

until the user clicks the Track Latest button at the upper right of the tab.


74

Alarm events are posted both to the Events and Reachback tabs and can be “sent to Reachback” from

either tab.

Figure 41 Sending Alarm Event Information and Spectra to Reach- back Recipient.

6.2.3.1 Send to reachback

This information is pre-defined on the Reachback tab as discussed in Setup and Options (Section 5). This

function is available from either the Events tab or the Reachback tab but only while using the “Survey”

and “Review” modes. To learn more about using the Reachback tab, see Section 5.3.6.

Right-click the event of interest, select Send to Reachback (Figure 41), and confirm that you wish to

email your Reachback contact information about this event. Included in this email will be the N42.42-

format survey and background spectra for each detector in the group that posted the highest-confidence

ID for the event. If the Show Reach-back Questionnaire option is enabled in the Setup and Options

program, the form shown in Figure 20 will open in a popup window. Fill it out according to your

operating procedures and click Save to transmit.

Reachback events are sent one-at-a-time. The questionnaire attachment is named “Reach-back question-

naire.xml” and the N42.42 filename is based on the radionuclide identified. For example, “spectra for

identification of ‘U-235' .xml”. If you are sending multiple reachback events to the same recipient,

questionnaires and N42.42 files with the same filename must be renamed to avoid overwriting the

previous file sent.


75

6.2.4 Alarms Tab

The Alarms tab (Figure 42) is a quick visual reference to all outstanding alarms. This tab is similar in

layout to the Events tab except that it only shows Active, Unacknowledged, and Acknowledged alarms.

The Duration field tracks the length of time an alarm is present.

Figure 42 User Interface Program “Alarms” Tab With Acknowledged and Unacknowledged Alarms.


76

6.2.5 Detector Health Tab

When the System Startup program is running, all properly connected and communicating detectors are

polled sequentially every 10 minutes and the results displayed on the Detector Health tab (Figure 43). In

addition to polling date and time and detector name, the state-of-health information includes parameters

such as bias voltage, detector temperature, gain stabilizer settings, detection mode (e.g., Idle, Search,

Background, etc.), the cooler’s elapsed run time since the most recent startup, gamma and neutron count

and dose rates.

Any detector that is included in the system configuration but not connected generates an alarm but

does not create a health record since it is not communicating and therefore cannot transmit

information.

Figure 43 Detector Health Tab.


77

6.2.6 Charts Tab — Signal and Threat Indexes

The Charts tab displays the Signal Index and Threat Index, and the optional Neutron Count Rate chart

(see Figure 44). These “virtual strip charts” can indicate nearby radioactivity even before IDs and alarms

are generated. Both charts scroll from right to left with time, providing short-term data trends. Keep in

mind that these are indirect indicators meant as quick visual tools, not count-rate or dose-rate

meters.

NOTE: The most recent point on the charts always reflects the current measurement on the

Measurements tab. During a survey, to see the most recent measurement update in real time, click the

Track Latest button at the upper right of the Measurements tab.

Figure 44 Charts Tab — Signal and Threat Index “Strip Charts” for Am-241 and Neutron Alarms.

• The Signal Index is based on the sum of the net gamma count rate from all detectors for all

detected radionuclides. The peak height on this chart increases as you move the detector

subsystem(s) closer to a gamma source. When an alarm is generated, the section of chart for that

time interval is assigned the same color as the alarm. For simultaneous alarms, the chart displays

the color of the highest-priority alarm.

• The Threat Index is a function of the maximum confidence factor for all threat nuclides in the

library, and always reflects the highest-confidence ID of threat nuclides from any one detector.

Threat nuclides include U, Pu, Np, Am, and neutrons (see also Appendix A). The peak height on

this chart increases as you move closer to a threat material.

• The Neutron Count Rate chart is only displayed if you select the Show Neutron Data option in the

Setup and Options program (not all Detective® series instruments have a neutron detector).


78

Figure 44 shows an ID and alarm for the threat IDs Am-241 and Neutrons on Fe. Note that the Signal

Index indicates a relatively weak radiation source, while the Threat Index and Neutron Count Rate chart

reflect a high probability that the source includes threat nuclides as well as a neutron emitter.

NOTE: The most recent point on the charts always reflects the current measurement on the

Measurements tab. During a survey, to see the most recent measurement update in real time, click the

Track Latest button at the upper right of the Measurements tab.

6.2.7 Status Tab — Detector Group Diagram

Figure 39 shows the Status tab, which provides a visual representation of your search vehicle and detector

array for each measurement in a survey. For each measurement associated with an alarm, the detector

group with the highest-confidence-level ID is highlighted with the corresponding alarm color, as shown in

the figure. The appearance of this tab is configured in the Setup and Options program (see Section 5.3.9).

6.2.8 Map Tab

The Map tab (Figure 45) displays real-time measurement locations and detection events on almost any

map system.

Figure 45 Map Tab Features.

For location data to be collected and displayed on the Map tab:

• The map tiles for the current survey area must be seeded (pre-cached) on the analysis computer to

make them available on the Map tab, unless you have internet access during the survey; (see

Section 9.3).

• The GPS antenna must be connected to the analysis computer and receiving satellite data or no

mapping data will be collected (however, all other survey data will be available). For instance, if

you pass through a tunnel and lose GPS signal, the breadcrumb trail on the map will be

interrupted until the GPS signal is restored.


79

6.2.8.1 Toolbar

The toolbar at the bottom of the map (Figure 46) controls the major map features.

• The “Settings” button on the left lets you customize the appearance of the breadcrumbs and

detection zones (Section 9.1). These changes can be made at any time in any mode that displays

the Map tab.

Figure 46 Map Toolbar.

• The next button is the droplist of available maps (the default Street Maps is shown here).

• The third button lets you choose the measurement type being tracked by the breadcrumbs.

• Use the “Show/Hide Layers” to control display of the data layers.

• Auto Tracking determines whether or not the map automatically repositions as the detector group

changes location15

. When all entries on the list are disabled (unmarked), you can pan to any point

on the map. Note that this auto-tracking feature is independent of the tracking feature for

the other tabs.

15 In most systems, all detector groups will be mounted in the same monitoring vehicle. However, as long as all

groups remain in range of the analysis computer’s WLAN, they can be parsed into one or more vehicles and /or

stationary arrays. Consult your ORTEC® Representative for more information.

6.2.8.3 Data Markings

There are four map icons / indicators types:

Location

The “car”-shaped location icon marks the current position of the search system.

Measurement

The survey path and analysis results are represented by measurement icons frequently

referred to as “breadcrumbs”, which represent one of the five Detective-Remote®

measurement types:

1) Gamma count rate (cps)

2) Gamma dose rate (mrem/hr)

3) Signal index

4) Threat index

5) Neutron count rate (cps)

• Single breadcrumbs represent one measurement (approximately 1 per second).

• Double breadcrumbs represent two or more measurements, depending on the

map zoom level.

• The default breadcrumb color is light blue; Figure 45 shows bread-crumbs

color-customized to the Threat Index value.

• Hover over a breadcrumb to display its Measurement information in a pop-up

(Figure 47). This pop-up displays information about each measurement under

the breadcrumb.

• To see all measurements under the breadcrumb, click “View All”.

• Double-click a measurement to synchronize it with the corresponding entry on

the Measurements tab.


82

Event

• Marks the location at which an alarm was generated with a triangle.

• For nuclide IDs, it marks the measurement at which the highest-confidence ID

was calculated by the analysis engine.

• You can customize the color of the triangular ID event icons (Section 9.1). By

default, innocent ID events are blue ( ) and threat ID events are red ( ).

• Hover over an Event icon to open its Event information popup (Figure 48). This

popup lists information about each event under the triangle. To see all events

under the triangle, click “View All”.

84

6.2.9 Spectrum Tab

Use the Spectrum tab (Figure 50), together with the Measurements tab, to view a specific detector’s

spectra and optionally generate .CHN-format survey and detector background spectrum files.

We recommend arranging the screen with the Events and Measurements tabs (also, optionally, the

Reachback tab) stacked together on one side and the Spectrum tab on the other.

Figure 50 Spectrum Tab.

To create a spectrum:

• Choose a Detector from the droplist,

• Double-click the measurement number at the end of the desired data slice,

• Enter the desired Duration in seconds, and the spectrum window will display the summed spectra

from the start time to the Measurement time. (The start time is the measurement time minus the

duration, in seconds)

• The Display options allow you to adjust the color and vertical scaling.


85

6.2.9.1 Creating Spectrum and Background Files for any Measurement

Detective-Remote® lets you generate ORTEC

® .CHN format spectrum and background files for any

system detector or detector group. This can be done in either the Survey or Review modes. The procedure

involves locating a particular measurement, loading its information into the Spectrum tab, selecting a

specific detector, and choosing how much data (in terms of detector live time) to include in the .CHN file.

As noted above, we recommend arranging the screen with the Events and Measurements tabs (and

optionally, the Reachback tab) stacked together on one side and the Spectrum tab on the other.

Note that you can also generate N42.42-format survey and background spectra for your own use by

sending yourself a reachback email. See Section 6.2.10.

1) On the Events tab, double-click an ID event of interest. This will synchronize the Events and

Measurements tabs such that the latter highlights the measurement with the highest cumulative Q

value for the event.

� The measurement’s detail box will list the data integrator(s), group(s), and Q value(s) for each

radionuclide ID made during that measurement.

� The measurement time in the Date column will be the ending live time for the .CHN file.

2) On the Spectrum tab, select the desired Detector and enter the Duration of the data slice you wish

to save in the .CHN file. The maximum duration is the measurement time minus the survey start

time.

3) Return to the Measurements tab and double-click the measurement to load the time slice into the

Spectrum window. NOTE: If no spectrum is displayed, try increasing the Duration and double-

clicking the desired measurement again.

4) Click Save and select the Destination Folder. Each save operation creates the specified spectrum

file plus the detector’s currently valid background spectrum. These files can be viewed in

MAESTRO or its accompanying WINPLOTS spectrum plotting application.

5) To create a .CHN file with a different Duration, enter the new value, return to the Measurements

tab and double-click the measurement again, then Save.

6) To create a .CHN file from a different measurement, enter the desired duration, go to the

Measurements tab and double-click the desired measurement, then Save.


86

Figure 51 illustrates this process, starting with identification of an event of interest on the Reachback tab.

The .CHN file contains 30 sec of data starting at 5:32:54 pm and ending at the measurement time.

NOTE: As of this release of the User Interface program, the Reachback tab is not synchronized with the

Events tab. Therefore, switch to the Events tab, locate the desired event and double-click it, then work

between the Measurements and Spectrum tabs as described above.

Figure 51 Create .CHN Files for the Selected Measurement and Duration.


87

6.2.9.2 Spectrum File Naming Convention

The naming convention for survey spectra is:

DR[sysno][surveytype]-[database].YYYYMMDDhhmmssUTC.det[#].[dur]Sec.chn

Where:

• DR[sysno] is the Detective-Remote® system number (for users with more than one system on the

same computer[s]);

• surveytype is Search or Standin;

• the database name is displayed in the Unique ID column in the Review dialog (Figure 65);

• YYYY is the acquisition year, MM the month, DD the day, hh the hour (UTC), mm the minutes,

ss the seconds;

• # is the detector system number (described below);

• dur is the Duration in seconds, where the number of digits is 3 or more (i.e., all times from 1–999

seconds are expressed in 3-digit format).

The convention for background filenames is:

DR[sysno][surveytype]-[database].det[#].bkg.chn

Where:

bkg indicates this as a background file for the indicated database and detector.

The detector system number (#) is shown on the Detector listbox on the Spectrum tab, and reflects the

order in which the instruments were added to the system, not the detector names and numbers displayed

in the Setup and Options program and MCB Configuration.

Example:

Figure 51 shows that this measurement was collected during a Search on March 11, 2014, at 5:33:24 pm

Eastern Standard Time. The spectrum for Detector 1 was saved, and the Duration setting was 30 seconds.

Given the database name 56531ffe-a3ab-4327-9cf5-56ee6932e069, the resulting .CHN files are named:

DR1Search-56531ffe-a3ab-4327-9cf5-56ee6932e069.20140311223324UTC.det1.030Sec.chn

DR1Search-56531ffe-a3ab-4327-9cf5-56ee6932e069.det1.bkg.chn

The files in the example above, the first file is the search spectrum and the second one is the Detector 1

background file.


88

6.2.10 Reachback Tab

The reachback settings are selected / defined in the Setup and Options program (see Section 5.3.6).

This tab, on the left side of Figure 52, is available in the Search, Stand-In, and Review modes, and

displays the list of events that can be sent to a reachback recipient.

Figure 52 Reachback Tab.

If you select an event for reachback and no Recipient information has been entered in the Setup and

Options program, a window will open in which you can enter recipient information. The information you

enter at this time will subsequently be saved / displayed on the Reach-back tab in Setup and Options for

future use.

A reachback transmission always includes an N42.42-format file containing the survey and background

spectra for each detector in the group that generated the highest-confidence ID for the selected event.

If the “Show Reach-back Questionnaire” option is enabled, the questionnaire will be displayed below the

list of events. Otherwise, the lower section of the tab will be blank, and only a brief description of the

event will accompany the N42.42 file.


89

The questionnaire attachment is named “Reach-back questionnaire.xml”, and the N42.42 filename is

based on the radionuclide identified, for instance, “Spectra for identification of ‘U-235' .xml”.

Reachback events are sent one-at-a-time. If you send multiple reachback events / alarms to the same

recipient, and the questionnaires and N42.42 files have the same filename, they must be renamed to avoid

overwriting prior email attachments. When finished entering information, Click Send.

6.3 Rearranging the Tabs

The User Interface program lets you choose which tabs will be displayed in each mode, as well as their

grouping, order, and size.

You can make any tab a new tab group simply by clicking the tab name and dragging to one of the five

destination hotspots — left, right, up, down, center — illustrated on the layout guide, which appears as

soon as you start dragging a tab (see Figure 53).

• This guide allows you to specify where you want the tab to be positioned with respect to other

tab(s).

• If you drop the tab on the right side of the guide, you will position the tab to the right of other

tab(s).

• The same is true for the top, bottom, and left positions on the guide.

• If you drop the tab in the center of the guide the tab will be stacked with the other tab(s).

• You can also undock a tab and allow it to float.

Figure 53 The Layout.

The following figures demonstrate tab regrouping.


90

Figure 54 shows the Alarms tab being moved to the right side of the window, according to the following

instructions.

1) Click and drag a tab until it undocks from the others. This will display the layout guide.

2) Move the undocked tab to the desired part of the screen then, still holding down the left mouse

button, roll the mouse arrow over the desired hotspot on the layout guide. The corresponding part

of the screen will change color.

3) Release the left mouse button and this tab will form a new tab page arrangement.

4) To add another tab to the new arrangement, drag it over the new group, roll the mouse arrow over

the center hotspot on the layout guide, and drop the tab.

5) Click and drag tab names within a group to rearrange them left to right, and click and drag the

boundaries of the groups to adjust the size of the various elements.

6) To ungroup, simply drag all tabs over the same section of the screen and drop them in the guide’s

center position.

7 BACKGROUND MEASUREMENTS

This chapter describes how to perform background measurements to minimize both nuisance alarms and

detector gain stabilizer errors. See Section 4.3.2 for a conceptual overview of the background NORM

“filtration” technique employed by Detective-Remote®.

7.1 General Guidelines

Your site operating procedures should determine how frequently and when to perform background

measurements as well as how long to count. However, the following are best practices and we strongly

recommend their incorporation in your site procedures.

IMPORTANT

All background measurements must be performed within in the Detective-Remote® program.

Backgrounds performed in the identifier’s standalone user interface program are not used by the

Detective-Remote® program.

• Perform a background measurement each time the system is moved to a new site. This will reset

the Detective®-200's gain stabilizer and determine the local net background count rate for each of

the NORM peaks listed in Section A.2.

• The Default count time preset and Background expiration period are on the Acquisition tab in the

Setup and Options program (Section 5.3.3.2). The minimum background count time is 1200

seconds (20 minutes). However, we recommend a minimum count time of 1500 sec (30 minutes)

for best system performance.

• If a Detective® is turned off, warmed above operating temperature, and re-cooled, you must run a

new background which will automatically center the K-40 peak in the factory-set calibration

channel and zero the gain stabilizer around that channel.

• If you use a Detective® as soon as it cools to the maximum operating temperature, perform a

background before use. After a few hours, when the detector is cooled to the operating set point,

run another background to reset the gain stabilizer.

• If at any time a Detective® posts a gain stabilizer or FWHM (full width at half maximum) error,

note the detector temperature and cooler drive voltage as discussed in the hardware manual, and

run a new background to reset the gain stabilizer. If the error recurs, consult your ORTEC®

Representative or contact ORTEC® Technical Services Group.


93

IMPORTANT

If you are operating where there is little or no naturally occurring K-40 (for instance, at sea), we strongly

recommend the use of a K-40 source (e.g., a low-sodium salt substitute containing potassium chloride).

If K-40 is absent during a background measurement the gain stabilizer is disabled, and remains disabled

until another background is performed with K-40 present. Operating with the gain stabilizer off can

reduce system performance.

7.2 Performing the Background Measurement

1) To start a background measurement, remove all nearby radiation sources (except an optional K-

40 source) and click the Background button. Figure 56 shows a count in progress.

Figure 56 Background Measurement In Progress.

2) Check the detector indicators to ensure all are counting. If one or more detectors are still in Idle

mode, click End Background then restart the count. If all detectors do not start counting, begin

troubleshooting network and detector problems (start at Section 10).

3) The background routine performs one or more adjustment cycles to re-zero the gain stabilizer

aligning the 1460 keV K-40 peak. The current adjustment cycle is displayed in the detector

“status indicator”, as shown in Figure 56. After the final adjustment cycle the background is

performed. If one detector in a multi detector system requires multiple adjustment cycles, the

background count time restarts for all detectors after the final adjustment cycle.


94

4) If you wish, you can extend the count time by clicking the Add 5 minutes button as many times as

desired. (Note that you can only use this feature before the count time elapses; i.e. you cannot

restart a completed background measurement and add more count time to it.)

5) To manually abort a background count, click End Background.

• If the minimum count has not elapsed yet for all detectors, an “are you sure?” dialog will

open (Figure 57). If you abort now, the previous set of background spectra will remain in

use until the next background measurement is completed.

• Note : If the Background expiration period specified in the Setup and Options program

(Section 5.3.3.2) has transpired, you must complete a new background measurement

before the system will enter Survey mode.

• If you abort after the minimum count time has elapsed, the new background measurement

will be put into effect. When the “are you sure?” dialog opens, click “End Now”.

Figure 57 Abort Background Measurement or Continue?

6) When the background count reaches the count preset (or is manually stopped after the

minimum1200 seconds have elapsed for all detectors), the user interface and detector status

indicators will return to Idle mode. The comment for the BKG Ended event will list the number

of cycles and total count time for each detector in the system (Figure 58).

Figure 58 Background Measurement Information on Event Tab.


95

7) The new background data for each detector will be stored in the system database on the analysis

computer, and will be used in all data analysis until the next background measurement is

performed.

7.3 Viewing the Detector Background Spectra

To generate a detector’s background spectrum in the .CHN format, see Section 6.2.9.1.

8 SURVEYING FOR RADIATION

This discussion assumes that all Detective-Remote® System Startup software components are running

during the entire survey.

• If for any reason the Detective-Remote® System Startup program is closed during a survey, see

Section 10.1for recovery instructions.

• If a detector stops communicating, see Section 10. If the User Interface program is closed during

a survey, simply restart it.

8.1 Starting a Search or Stand-In Survey

To start a survey, click Search or Stand-In (Figure 59).

Figure 59 Start a Survey.

The top left of the screen will switch from the “System Is Idle” display to the “Collecting Search” or

“Collecting Stand-In” header.

Figure 60 Enter Optional Description.

An optional search description field will be displayed to the right of the “Collecting...” header (Figure

60). We recommend an entry, in addition to the timestamp, which will help you locate older surveys for

review.

An entry in this field will be displayed with the search date and time. The description can be changed any

time during the survey or in Review mode.

When the search is started, the status indicators on the Detectors tab will switch from “Idle” mode to the

mode selected, (Search, Stand In, Background, or Review). If you have selected the “Strip Charts Tab”

from the “Show” menu to be displayed, the strip charts on the “Charts” tab will begin scrolling from right

to left. At the same time, new measurements will begin posting on the Measurements tab.

• Search — Figure 61 depicts a Search in progress. The screen is arranged into three tab groups

displaying the Maps, Charts, and Measurements tabs. Note the unacknowledged alarm for Am-

241 at the bottom of the Event History list. This ID is reflected by the Signal Index and Threat

Index, as well as the Acknowledge: Am-241 button. To end this survey, click “End Search”.

• Stand-In — Figure 62 shows 3 screen shots of selected screen features from the “Stand-In”

survey. Note the countdown timer below the “Collecting Stand-In” header. To end the survey

before the preset count time, click “End Early”. To extend the length of the Stand In survey, click

“Add 30 Sec”. To extend the count you must do this before the end of the preset count length.


97

The count length may be extended as many times as needed, as long as it is extended before the

time ends.

• LCX Mode — Figure 63 shows a Search performed in the LCX mode (Section 4.3.3), in which

low- confidence IDs are posted as “suspects” on a yellow background. Note that the data point

description for each Event includes the LCX setting.

Figure 61 IDs and Alarms during a Search (Standard ID Mode).

Figure 62 Stand-In Survey screen features.


98

Figure 63 IDs and Alarms shown are during an LCX Mode Search.

8.1.1 Adding Comments to Pop-Up Alarm Boxes

If the “Show popup box on source identification” option is marked in the Setup and Options program, you

can enter a comment for alarm notifications. Comments are saved to the “Events” log of the survey.

Figure 64 shows the pop-up alarm box for a Eu-152 alarm with a comment noting where the ID was

made. Note that the “Event log” shows a comment has been entered for this ID event. Clicking the event

displays the comment text.


99

8.1.1.1 Creating Spectrum and Background files for a Detector

See Section 6.2.9.1. Note also that you can generate N42.42-format survey and background spectra by

sending yourself a reachback email. See Section 6.2.10.

Figure 64 Adding a comment to the “Event Log”.

8.2 Review Mode

Review mode allows you to view any survey stored on the analysis computer. You can optionally

generate survey and background spectrum files, email detection event information and spectra to a

reachback contact, and add or edit the survey description.

In addition, this dialog enables you to identify survey database files for export, as well as review imported

survey databases. See Appendix C.

• To locate a survey for export, click the Review button to open the Review Survey dialog (Figure

65), locate the desired survey, and view the survey’s Unique ID.

• To review a survey, scroll to the desired survey and double-click it or highlight it and click “Open

all tabs” except Alarms are available in this mode. As you move through the entries on the

Measurements tab (by clicking on a measurement or press the up/down arrow keys), the strip

charts, Status tab, and data point detail box will display the data for each measurement (Figure

66). Other data synchronization features are discussed in Section 6.1.1.6. Double-click an event

or measurement to load the relevant map tiles.


100

IMPORTANT

If you review a survey for which the map tiles are not cached on the analysis computer, — for instance,

an imported survey or a survey in which you accessed the OSM map in real-time via a cellular modem —,

you must connect the computer to the internet and either access the ORTEC® web-based map server in

real time, or pre-cache the surveyed area’s map tiles for offline review. Otherwise, the Map tab will not

display the survey’s map data. If an alternate map system has been loaded on the analysis computer

(computer 2 on a dual computer system), no internet connection or pre-caching is required.

Figure 65 Choose a Survey for Review.

• To generate measurement and detector background files in the ORTEC® .CHN format, see

Section 6.2.9.1.

• On the Map tab, you may change the color of the measurement types, detection zones, and event

icons as needed to better visualize the survey data (see Section 9.1).

• Reachback information can be sent from the Event and Reachback tabs. See Sections 6.2.3.1 or

6.2.10.


101

NOTE: Should a “live” system error occur while you are in “Rreview” mode , the “live” “Acknowledge”

button (and Alarm popup, if configured) will activate and the interface will turn amber, however, you will

not see the alarm on the review “Events” tab. This is because you are reviewing the events from a stored

survey. When you exit “Review” mode, the live “Events” tab will display the error entry.

Figure 66 Reviewing the Charts and Measurements from a Past Survey.


102

9 MAPPING

Detective-Remote® uses the powerful, versatile “Sensor Portal Mapping Platform” to generate real-time

maps during your mobile surveys. The mapping function displays route, measurement points, and the

location of any ID events. This chapter tells how to customize your maps, how to add and configure an

alternative map source to the analysis computer, and how to pre-cache (seed) map tiles for field use.

For more detailed instructions on the Sensor Portal’s extensive capabilities, see the accompanying

“Sensor Portal and Map Control, User Guide”.

9.1 Customizing Your Map Graphics

This section tells how to change the default appearance of the event icons, measurement breadcrumbs,

and detection zone graphics on the “Map” tab in the “Detective-Remote® User Interface” program. The

“Settings” menu on the toolbar, (Figure 67), is the access point for these options. All colors and settings

can be changed at any time from the “Map” tab in the User Interface program.

NOTE: Colors are not saved with the survey data. Rather, the current color settings are applied when you

review a survey.

Figure 67 The Settings Menu.


103

9.1.1 Edit Event Colors

This function (Figure 68) lets you change the color of the five Detective-Remote® event levels, e.g., Low,

Normal, High, Urgent, and Immediate (no other settings can be changed). Detective-Remote® uses the

“Normal” level for innocent ID events and “Immediate” for threat ID’s or in LCX mode for suspect IDs.

To change the “Event” colors, first select the desired measurement type from the map toolbar, then click

Settings / Edit Event Colors.

After making changes Click “OK” to accept and save any changes or “Cancel” to exit without saving

changes.

Figure 68 Edit the Event Icon Color.


104

9.1.2 Edit Measurement Colors

The default breadcrumb for all five measurement types is a medium blue.

To change color, first select the desired measurement type from the map toolbar, then click Settings / Edit

Measurement Colors.

To change the breadcrumb color, you must create at least one entry in the Choose Measurement Colors

dialog, shown on the left in Figure 69. If no initial entry has been defined in this dialog, click the +Add

button. This will open the Set Measurement Threshold dialog (right side, Figure 69).

Figure 69 Change Breadcrumb Color and/or Create Color Gradient.

NOTE: Set the threshold value (at the top of the dialog) to zero. Otherwise, measurements that fall below

your lowest threshold will be the default blue.

Click the desired color on the color wheel and click OK to return to the Choose Measurement Colors

dialog.

The new entry will be displayed as a thumbnail of the color and threshold value, along with Edit and

Remove buttons.


105

You may add as many entries as you wish. For example, Figure 70 shows a five-color gradient for the

Threat Index.

Figure 70 Creating a Color Gradient.

Click OK to accept any changes or Cancel to exit without changes.

NOTE: As of this release, Remove entries from the end (bottom) of the list; otherwise, the User Interface

program may lock up or crash. If this happens, simply restart the User Interface and return to the Map tab.


106

9.1.3 Edit Detection Zones

This screen lets you customize the color and extent of the detection zone indicator displayed on the map

with each ID event icon. All existing detector group sensors are listed on the Detection Zone

Configurations screen (left side, Figure 71), and depict the orientation of the detection zone as the survey

vehicle points up (i.e., in the same direction as the vehicle/array graphic on the Status tab).

Figure 71 Configuring a Detector Group’s Detection Zone Graphics.

Click the “Change” button for any group to access the Detection Zone Configuration screen. To change

the color, click the desired spot on the color wheel.

To adjust the zone size and extent, click the Settings tab. Use the Arc Width slider and Depth field to

adjust the size of the zone (typically, this will be based on the maximum detection distance and detector

group FOV). Then use the Angle slider to orient the detector group FOV with respect to the survey

vehicle/array.

Click OK to accept any changes or Cancel to exit without changes.

NOTE: We recommend setting the Min. Display Speed to zero. Otherwise, if the survey vehicle is

traveling below the minimum speed when an ID event occurs, the detection zone for that event will not be

marked on the map.


107

Note that overlapping detection zones combine each zone’s color and opacity. Figure 72 illustrates this

for the three detection zone colors shown on the left in Figure 71.

Figure 72 Detection Zone.

9.2 Adding Alternate Map Layers to Detective-Remote®

This section is applicable only if you will be using a map source other than the default “Open Street

Maps”.

IMPORTANT

Alternate map layers are stored in their entirety on the analysis computer. Therefore, if you intend to use

only your added map layers, rather than the default OSM, there is no need to connect to the internet and

download a cache of map tiles from the map server before going into the field. However, if you plan to

use the OSM as well as your own map(s), you must pre-cache as discussed in Section 9.3.

1) Before starting if the User Interface program is running, close it.

2) Obtain the alternate map data. This data will likely be in one of the following formats:

• Directory of spatial files (shapefiles) ArcGrid

• PostGISGeo TIFF

• PostGIS (JNDI) Gtopo30

• Properties ImageMosaic

• ShapeFile WorldImage

• Web Feature Server WMS


108

3) Copy the alternate map data to the following folder (Figure 73):

C:\Program Files (x86)\GeoServer\data_dir\data

Figure 73 View of Alternate Map Folder.

4) Start the Mapping Setup interface by typing “ map” in the Start Menu “Search programs and

files” box and select “Mapping Setup” from the search results.

Or

select: Start > All Programs > Sensor Portal > Mapping Setup

This will open the GeoServer map server interface in the default web browser (Figure 74).

116

9.2.1 Registering the New Map in Sensor Portal

Now that your map (layer) has been linked to the GeoServer interface, you must make it available to the

“Sensor Portal” interface. To do this follothese steps:

1) The first step is to ensure you know the new map’s name, including uppercase and lowercase

letters, symbols, etc.

To do this, click “Layers” on the left sidebar to open the “Layer Preview” screen. The new layer’s

name will be displayed in addition to the name of the default “Open Street Maps”.

In the example shown in (Figure 83), the new entry is “Maps:USA_ roads”.

5) In the Add Map Layer window (Figure 87), enter the following information:

• Enter a descriptive Display Name for this layer (our example: USA Roads).

• From the Layer Type droplist, select the WMTS Layer entry. NOTE: This layer type will

be valid for almost all maps compatible with Detective-Remote®. If you obtain

unexpected results, contact our Technical Services Group.

• In the URL field, enter the following URL seen below, be sure to correctly spell the

lowercase, 13-character server name “detective-rmt: “.

o http://detective-rmt:8080/geoserver/gwc/service/wmts

• In the Layer Name field, enter the name identified in step (1) of this section (in this

example it was Maps:USA_roads ), be certain that the name is entered exactly as

written in Step 1.

• The remaining fields can be left blank.

Figure 87 Add Map Layer.

7) To confirm the new layer is correctly registered in Sensor Portal, click its corresponding Preview/

Seed link. After a few seconds of initialization, verify that the preview dialog shows the map

contents (Figure 89).

Figure 89 Preview Displays New Map.


121

8) Close the GeoServer and Sensor Portal interfaces by exiting the web browser.

9) The next time you start the User Interface program, the lower-left corner of the Map tab will

display a droplist menu in the lower left corner as shown in Figure 90. This droplist will contain

all the available map layers. You may switch between map layers at any time.

Figure 90 New Map in User Interface Map Tab.


122

9.3 Seeding (Pre-Caching) Maps

Detective-Remote® mapping requires you to pre-cache or “seed” the analysis computer with a targeted set

of map tiles for your area(s) of interest when connected to the internet16

.

• You can seed maps without exiting the User Interface or System Startup applications.

• Each time you prepare to survey a new region, you must pre-cache its map tiles from the map

server.

• Once you have downloaded map tiles for a particular area, they are retained on the analysis

computer for use without reseeding.

• The map cache is located in the C:\Program Files (x86)\ GeoServer\Data_dir\gwc folder.

• The time required to download map information depends on the size of the area, the level of map

detail you request, and the speed of your internet connection. It can take from several minutes to

many hours. A little experimentation will show you the amount of time required to download the

map data needed for your next set of surveys. If time is a factor, a good way to test the speed is by

seeding less detailed maps first. Add more detailed layers as needed or as time allows.

IMPORTANT

Seeding requires internet access. For wired systems, you may connect via any means, wired or wireless.

For wireless systems, connect via wired eEthernet, or a Bluetooth or wired USB tether. If you connect to

another wireless network, in almost all cases the current ad hoc network’s fixed IP address will be

incompatible with the other network. In such cases, Windows will offer to automatically “fix” the

problem. If you allow this “fix,” Windows will switch the computer to dynamic IP addressing and erase

the fixed IP address. You must restore the ad hoc wireless network’s fixed IP address (Section B.5) before

you can reconnect to the Detective-Remote® system.

To pre-cache map tiles:

1) Connect the analysis computer to the internet.

2) Launch the Sensor Portal interface by entering “ sens” in the “Search programs and files” box on

the Start panel then selecting the “Sensor Portal” search result (or select Start > Program files >

Sensor Portal). It may take several minutes for the interface to load in the default web browser

(Figure 84).

16 Unless you have real-time internet access in the field via cellular modem or tethering to a mobile phone.


123

3) Click the red “Administration” tab (Figure 85), then on the lower-left select “System Settings”

icon to display the screen shown in Figure 91.

Figure 91 System Settings Screen.


124

4) In the Map Layers section, click the “Preview/Seed” link for the desired map (Street Maps in the

example figure). This will open the map preview window (Figure 92).

Figure 92 Pan and Zoom to Display the Desired Map Area.


125

5) Click and drag (or use the arrow keys) as needed to pan the mapto your area, then click the +/-

buttons in the map window to zoom in until the desired survey area is bounded by the preview

window (Figure 93).

Figure 93 Right-Click to Open Menu, then Select the Map Detail Level to Begin Seeding.

6) Right-click the map window to display the “popup menu” shown in Figure 93, then click on the

level of map detail to be downloaded. Most users select the Seed everything (very slow) option.

Map seeding will start immediately.

7) Right-clicking on the Preview map will display the seed progress as a percentage. The Abort

button is located below the progress indicator. If seeding takes too long, you may abort at any

time. This will return you to the map preview window. Select a smaller map area or a lower level

of detail and try again.

8) When seeding is complete, close the web browser and disconnect the system from the internet.

The seeded map content will now be available offline.


126

10 TROUBLESHOOTING

10.1 If You Close an Application or Sleep the Computer During a Search

Closing the “User Interface” does not affect an in-progress survey (or a review or background

measurement). Simply restart the application.

Closing “Detective-Remote® System Startup” program is interrupted during a survey, either by accidental

program shutdown or by putting the computer in sleep mode, when the program is restarted, the survey

will still be in Search mode and will register the survey as being in progress. However, there will be a gap

in the data corresponding to the amount of time both programs were not jointly operating and this gap

may render the analysis invalid. The survey must be stopped and restarted.

1) If the Detective-Remote® System Startup program was accidentally closed:

a. End the survey

b. Restart the System

2) If the computer was put into sleep mode:

a. End the survey

b. Close both programs

c. Reboot the computer(s)

d. Reconnect the analysis computer to its ad hoc network

e. Reconnect the user interface computer and detector modules to the network

f. Restart the System Startup

g. Restart the User Interface programs.

In all cases, the virtual strip charts on the Charts tab will show no interruption in the data even though a

gap does exist. The gap will be evident on the Measurements and Events charts.


127

10.2 Wireless Issues, Detective®(s) or Computer Not Responding

Actions that interrupt communication between the analysis computer and one or more detectors:

• Allowing the computer to enter a sleep/hibernate/power-saving mode.

• Restarting the computer.

• Running the MCB Configuration program.

• Clicking the Check for upgrade and/or repair button on the Setup and Options program’s Server

tab while the System Startup application is running.

• Connecting the computer to another WLAN, which will delete the wireless adapter’s fixed

IPaddress.

• Moving one or more detectors out of range of the analysis computer.

1) Check the Detective®(s) that is/are not responding to ensure that the Mobile MCB Server screen

is displayed on the touchscreen (Figure 7) and the radio button for your system’s connection

method (Wireless/ActiveSync vs. USB Control) is selected.

2) If your wireless system has been switched to the USB Control setting, tap the Wireless/

ActiveSync radio button then restart the system as follows:

a. If all of the Detective®s have left the network, reconnect the computer(s) to the ad hoc

network according to Section 5.2.

b. Restart the disconnected Detective®-200(s): Press and hold the Detective

®’s On/Off

button for 1–3 seconds to display the power menu, then tap the Restart option (If the

Detective® does not respond to a quick press of the On/Off button, press and hold the

button for about 30 seconds until the unit reboots.) Restart takes a few minutes, after

which a series of screens including the Windows Mobile desktop will briefly be

displayed before the Mobile MCB Server screen is presented. The connection method

you selected before restart will still be selected (reboot does not change it).

3) For a USB system:

a. Confirm the USB Control radio button is displayed on the Detective®’s touchscreen.

b. Ensure all cables have continuity and are connected correctly.

c. There is no need to restart the computer(s) or Detective®(s).


128

4) If using a wireless system, the network connection may have failed. This occurs when:

a. The computer is rebooted

b. After running the MCB Configuration program (which is typically done only to add a

new detector to the system or troubleshoot a detector that does not show up in the system

configuration test),

c. If you accidentally run the Setup and Options program while the Detective-Remote®

System Startup application is running.

i. To recover restart the Detective®-200 computer as discussed in 2) b) above, then

reconnect the computer to the network according to Section 5.2 of this manual.

5) Very infrequently a Detective®’s Windows Mobile operating system stops responding to external

commands.

a. To recover, restart its computer as in 2) b) above.

10.3 GPS Issues (Franson GpsGate Icon is Red)

• When the Franson GpsGate GPS server is running and the GPS antenna is connected and

receiving satellite input, the Franson GpsGate icon in the system tray should be green ( ).

• When the GPS antenna is connected but does not have a satellite fix, the icon is yellow and the

DR icon is flagged with a yellow caution indicator.

• In all other cases, the icon is red ( ).


129

If connecting the GPS antenna does not change the icon to yellow or green:

1) Disconnect the GPS antenna.

2) Right-click the Franson icon and select Settings from the context menu (Figure 94).

Figure 94 Franson Conext Menu.

3) In the “Set input – from where data is received” section of the Settings dialog , click the Close

button. The button name will change to” Open”. Click the “Open” button then close the settings

dialog box. Reconnect the GPS antenna, and verify that the Franson GPS Gate icon turns yellow.

If the problem persists, contact ORTEC® Technical Services Group or your ORTEC

® Sales

Representative.

10.4 Forgotten Computer or Detective® Password. Do not lose or forget a password!

If you change the password on the computer’s Detective-Remote® account or if you set a password to

control access within the Detective®-200's Detective

® software application, be sure to keep track of the

new password. If you lose or forget your new password the system will have to be returned to ORTEC

® for an extensive (non -warranty) repair. Contact your ORTEC

® Sales Representative or the

ORTEC® Technical Services Group for assistance in returning your system.

B. ADDING DETECTORS TO YOUR SYSTEM

This appendix tells how to add ORTEC® identifiers and interchangeable detector modules to an existing

one or two computer Detective-Remote® system.

NOTE: Most of this can be done with just the computer(s) and the new detector(s)

i.e., if your existing system is mounted in a search vehicle, there is no need to sit in the vehicle to perform

most of the procedure.

B.1 Supported Instruments

This Detective-Remote® release supports the following ORTEC

® instruments and connection modes:

Wireless or Wired USB Wired USB Only

Detective®-100 T(firmware DETF-305 or later) ICS

Detective®-200 (DX and EX) IDM-200, IDM-200-V

Detective®-X LDM (firmware DETL-010 or later)

Detective-TDM

micro-Detective® (including HX and DX)

Micro-trans-SPEC (including UF6)

trans-SPEC-100 T(firmware TSDX-305 or later)

B.2 Required Materials and Resources

All necessary software and firmware upgrades are available from ORTEC®.

• The hardware manual for the detector module.

• For wireless configurations, the current release of the ORTEC® Mobile MCB Server.

• For all configurations, the current release of the ORTEC® Connections Driver Update Kit (P/N

797230).

B.3 System Checks and Software Upgrades

For a two-computer configuration, perform these system checks and software upgrades on both computers

unless otherwise indicated.

B.3.1 Ensure All Power-Saving Settings are Disabled

In the Windows Control Panel Power Options utility, ensure all power-saving and sleep/hibernate options

for the display, hard disk, wireless adapter, processor, USB ports, and all other computer components are

set to Never/Disable/Off for both “plugged in” and “battery” power sources. This will prevent

interruptions of data acquisition and wireless communication.


136

B.3.2 Ensure ORTEC® CONNECTIONS v8.04 or Later is Installed

This release of Detective-Remote® requires CONNECTIONS v8.04 or later to mediate communication

between the ORTEC® detectors and the system computer(s). If CONNECTIONS is already installed on

your computer(s).

Check the version by opening Windows Explorer, navigating to C:\Program Files (x86)\Common

Files\ORTEC® Shared\UMCBI, then hovering the mouse pointer over the mcbcon32.exe application to

display its File version, as shown in Figure 95.

Figure 95 Check the CONNECTIONS Version.

If necessary, obtain the latest CONNECTIONS Driver Update Kit (P/N 797230) from your ORTEC®

representative or our Technical Services Group. Install according to the update kit’s instructions, noting

the following:

1) Accept the default installation location.

2) On the Instrument Setup screen, select the USB-based instruments option.

3) To conserve computer memory resources and CPU time, unmark the Allow other computers to

use this computer’s instruments checkbox (unless you have a specific need to share the system

detectors with other network computers).

B.3.3 If Adding a Newly Purchased Detector

New identifiers and detector modules are shipped with the latest version of CONNECTIONS and

MAESTRO, both of which must be installed (on both computers in two-computer systems) in order to

obtain full performance from your new instrument. Install these new applications first, according to their

installation instructions.


137

B.4 Add New Detectors

B.4.1 Detector Modules without an Integrated Computer

These instruments — the IDM-200, LDM, and ICS — can only be connected via wired USB. Power the

module on, then cable it to the analysis computer. In most cases, Windows will install the instrument by

itself. However, if the “Found New Hardware” wizard opens, complete it according to the instructions in

the module’s hardware manual. Then return to Section 3 of this manual and continue installation and

configuration.

B.4.2 Portable Identifiers with Integrated Computer

These instruments — the Detective®-200, micro-Detective

® (including HX or DX), Detective

® EX or

DX-100, Detective® EX or DX-100T, trans-SPEC-100, trans- SPEC-100T and Micro-trans-SPEC

(including UF6)— support both wireless and wired USB connections.

1) For wired configurations, refer to the hardware manual (and the following content) and switch the

identifier to the MCA (spectroscopy) mode, then connect the identifier to the analysis computer

via USB cable. After the hardware installation routine has completed, upgrade/install Mobile

MCB Server, then go to Section 3 and continue installation and configuration.

2) For wireless configurations, go to Section B.5.1 and upgrade/install Mobile MCB Server. Then

go to Section B.5 for instructions on assigning the identifier a fixed IP address and connecting to

the analysis computer’s ad hoc wireless network.

B.5 Wired Configurations – Install the Identifier on the Analysis Computer

In wired configurations, portable identifiers must be in the MCA (spectroscopy) mode, as distinguished

from the ActiveSync or Data (standalone identifier/data transfer) mode. Refer as needed to the identifier’s

user manual.

1) For Detective®-100 and trans SPEC-100 units, connect the rear-panel CONTROL port to the

analysis computer with a USB cable.

2) For Detective®-200s, micro-Detective

® series units (including HX and DX), and Micro-trans-

SPEC series units including UF6, navigate to the identifier application’s USB control or

communication screen and tap the MCA Mode radio button. Then connect the unit to the analysis

computer with a USB cable.

3) In most cases, Windows will install the new identifier by itself. However, if the “Found New

Hardware” wizard opens, complete it according to the instructions in the identifier’s hardware

manual.

4) You are now ready to go to B.5.1 and install Mobile MCB Server.


138

B.5.1 Upgrade Mobile MCB Server on all Identifiers

NOTE: If you have also purchased new ORTEC® spectroscopy applications for your identifier(s) — e.g.,

the Micro-Detective®, trans-SPEC, or UF6 application — install them first and Mobile MCB Server last,

otherwise the new Mobile MCB Server version may be overwritten.

1) The Mobile MCB Server program (P/N 935604) is supplied on an SD card. Install it according to

its accompanying instruction sheet, and update all other identifiers in your system so all are using

the latest Mobile MCB Server and Launcher.

2) Referring to the identifier’s user manual, restart its computer. Boot-up may take several minutes.

The Mobile MCB Server will then auto-start, and will take 20–30 seconds to initialize (during

which time the Windows Desktop and other screens may briefly be displayed).

3) When startup is complete, the Detective® touchscreen should appear as shown in Figure 7.

4) For wired systems:

a. Detective®-100 and trans SPEC-100 units — Disconnect the identifier from the analysis

computer, tap the USB Control radio button on the touchscreen, then reconnect (the rear-

panel CONTROL port) to the analysis computer.

i. NOTE: To switch this type of identifier from wired USB connection to wireless,

disconnect from the analysis computer first, then tap the Wireless/ ActiveSync

radio button on the touchscreen.

b. All other identifiers — Tap the USB Control radio button on the touchscreen (no need to

disconnect the USB cable).

i. Tap Exit to Windows. This will display the Launcher screen (Figure 8).

ii. Confirm that the Mobile MCB Server checkbox is marked to ensure the system

self-recovers after power loss.

iii. Restart Mobile MCB Server and go to Section B.6.4.

5) For wireless systems, tap the Wireless/ActiveSync radio button on the touchscreen.

i. Tap “Exit to Windows”. This will display the Launcher screen (Figure 8).

ii. Confirm that the Mobile MCB Server checkbox is marked to ensure the system

self-recovers after power loss.

iii. Restart Mobile MCB Server and go to Section B.7.


139

B.6 Wireless Configurations

Connect to the Ad Hoc Wireless Network

B.6.1 Confirm the Wireless Network Connection Settings

Before assigning fixed IP addresses to the new detector(s), confirm wireless network adapter settings for

the computer(s).

NOTE: If your IT department assigns IP addresses for your network devices, the computer (or both, in a

two-computer system) will need an Internet Protocol Version 4 (TCP/IPv4) IP address and subnet mask.

1) If connected to a wired network, disconnect the Ethernet cable from the computer.

2) Start with the analysis computer. In the Windows Control Panel, open the “Network and Sharing

Center”utility (Figure 96).

Figure 96 Open Network and Sharing Center.


140

3) On the next screen’s left sidebar, click “Change adapter settings” (Figure 97).

Figure 97 Change Adapter Settings.


141

4) Right-click Wireless Network Connection (Figure 98), then select “Properties” to open the dialog

shown in Figure 99.

Figure 98 Select the Wireless Network Connection Entry.

Figure 99 Properties Dialog.


142

5) Make sure the checkboxes for all items except Internet Protocol Version 6 (TCP/IPv6) are

marked as shown in Figure 99, then double-click Internet Protocol Version 4 (TCP/IPv4) to

display its Properties dialog (Figure 100).

Figure 100 Set IP Address.

6) Confirm the following IP address settings for the analysis computer:

• IP address 192.168.0.100

• Subnet mask 255.255.255.0

7) Click OK twice.

8) From the Control Panel, reopen the Network and Sharing Center utility and select Change adapter

settings from the left sidebar.

9) Right-click the ad hoc wireless network connection and select Connect/Disconnect.

10) Find the new ad hoc network’s listing. If not connected, click the new entry then click Connect.

11) You may wish to record the IP address(es) for the computer(s)’s wireless adapter in a text file on

the analysis computer for easy access/recovery. To connect the computer to another network, we

recommend using wired Ethernet, or Bluetooth or wired USB tethering.


143

12) In two-computer systems, repeat for the User Interface computer, except that the IP Address in

step (6) above, should be 192.168.0.101 (i.e., increment the last digit in the fourth triad from 100

to 101).

B.6.2 Assign a Fixed IP Address to the New Identifier(s)

NOTE: If your IT department assigns IP addresses for your network devices, each identifier being added

to Detective-Remote® will need an Internet Protocol Version 4 (TCP/IPv4) IP address, subnet mask, and

gateway; and these must be compatible with the IP address(es) assigned to the computer(s) in the

preceding section.

Most ORTEC® identifiers use the Windows Mobile 6.1 Classic operating system; however, some early

units used v6.0 Classic, which in places used slightly different tab, button, and screen names. These are

noted in parentheses17

.

1) The analysis computer must be within range and connected to its ad hoc wireless network.

2) On the identifier, exit all currently running ORTEC® applications including any spectroscopy

applications, Mobile MCB Server, and Launcher.

3) Turn on the identifier computer’s wireless adapter:

• On the Desktop, tap the Start button, then the Settings entry,

• Tap the Connections tab

• Tap the Wireless Manager icon to display the Wireless Manager screen

• If the Wi-Fi (or Wireless LAN) button indicates the adapter is Off, tap to enable it. The

button will change from pale to bright green (blue), and the name of a wireless network

may be displayed below the button.

• Tap “Done” to return to the Connections tab.

17 At a glance, the v6.1 Desktop is green and v6.0 is blue. To confirm the operating system version, tap Settings,

System, About.


144

4) Tap the Network Cards icon to display the Configure Network Adapters screen (Configure

Wireless Networks screen, Network Adapters tab).

• Tap the entry for the wireless card (Marvell SDI08686 Wireless card). This will open the

setup screen.

• If your Detective-Remote® system was factory-configured as a wireless system, its

original identifiers should already have fixed IP addresses starting with 192.168.0.1 for

Detective® 1, 192.168.0.2 for Detective

® 2, and so on; i.e., only the last triad in the

address changes, incrementing by 1 for each subsequent identifier.

• All original detectors should all be using the factory-assigned Subnet 255.255.255.0 and

Gateway address 192.168.0.100; and all new detectors will use these same settings.

• For the first identifier you add to the system, assign the next IP address in the series. That

is, if the original system has four Detective®s, your first additional identifier, unit 5,

should be assigned 192.168.0.5.

NOTE: If your organization has more than one Detective-Remote® system, assign an IP address that has

not yet been used in either system. This will make it easy to transfer Detective®s from one system to

another.

• Enter the factory system’s Subnet entry, 255.255.255.0, and Gateway entry,

192.168.0.100.

• Tap OK twice to return to the Connections tab.

5) Repeat the preceding steps for all new detectors, incrementing the last digit of the IP address by 1

(.6 for unit 6, etc.), and using the same Subnet and Gateway entries for all detector modules.

6) You may wish to record the above settings for each identifier you add to the system, and save

them in a text file on the analysis computer for easy access/recovery.

B.6.3 Check Network Communication

Test each new identifier’s network connection by pinging it from the analysis computer.

1) On the Windows Start menu, type cmd in the “Search programs and files” box, and select the

CMD search result. This will open the command window (Figure 101).


145

Figure 101 Open the Command (CMD) Window.

2) At the C:\Users\DETECTIVE-REMOTE> prompt, type ping followed by a space, then the first

new detector’s IP address (in our example in the preceding section, this would be detector 5's IP

address,192.168.0.5).

3) Study the ping report and verify the computer and detector are communicating (Figure 102).

Figure 102 Ping Successful.

4) If communication fails, repeat the steps in Section B.6 to confirm the identifier’s IP address, then

ping again.

5) If communication still fails, use wired USB as a secondary connection method (see Section B.5

for setup). Otherwise, consult your IT department or ORTEC® Technical Services Group for

assistance.


146

6) Repeat for each new detector. When all new units are communicating successfully, proceed to the

next section.

B.6.4 Run the MCB Configuration Program

The next step is to run the MCB Configuration program from the “MCB add new” shortcut on the

desktop to establish communication between the analysis computer and the new detectors, wired and

wireless. This step has already been completed for the Detectives in factory configured systems.

However, when you add more detectors to the system, the MCB Configuration program must recognize

them before they are available in Detective-Remote®.

NOTE: If you change an identifier from wireless to wired connection, or vice versa, you must re-run

“MCB Add New” in addition to the setup steps discussed in the preceding section.

IMPORTANT

When adding a new detector module(s) to the system, always run “MCB Add New” from the desktop shortcut. Do not add new detectors from the MCB Configuration instance on the MAESTRO

menu.

This is because “MCB Add New” has the -P flag added to the MCB Configuration command line. This

flag lets you run MCB Configuration without all system detectors connected to the analysis computer.

Doing this allows you to take your analysis laptop or tablet out of the survey vehicle and into a building

or other workspace to add a new detector(s) to the system.

If you run MCB configuration from MAESTRO (without the -P flag) and do not have all detectors

connected, the disconnected detector units will be removed from the Detective-Remote® system. To

restore them to the system, you will need to reconnect them to the system in their wired or wireless

configuration, then run “MCB Add New” to add them back into the system.

1) On the Windows desktop, double-click the “MCB Add New” desktop shortcut. The resulting

dialog (discussed in detail in the CONNECTIONS and MAESTRO user documentation) should

display all of the Detective®s in your system.

2) New instruments will initially be assigned the ID Number zero (0), which must be changed to a

unique, non-zero number. For units in a wireless system, you may find it helpful to use the last

digit of the IP address as the detector number. To do this, double-click the new detector’s entry

and manually assign it a unique number. (For additional instructions on customizing detector

Numbers, see the CONNECTIONS Driver Update Kit documentation.)

3) IMPORTANT: Do not click the RENUMBER ALL button and do not renumber identifiers

that have already been configured in the Detective-Remote® Setup and Options program. If

you accidentally renumber previously configured units, rerun MCB Configuration, double-click

on each mis-numbered detector, and restore its original number.


147

4) If you permanently remove a detector from the system and want MCB Configuration and Setup

and Options to reflect that removal, connect all remaining system detectors to the computer(s)

and run the MAESTRO instance of MCB Configuration (without the -P flag). When you do this

all detectors not connected to the system will be removed from the MCB Configuration. This also

will subsequently remove them from “Startup” and “Detector Groups” tabs in the “Setup and

Options” program.

B.7 Confirm New Detectors are Available in Detective-Remote®

You are now ready to confirm the new detector(s) have been correctly integrated into Detective-Remote®.

1) Mount the new detectors in the search vehicle, and connect all system detectors to the analysis

computer by wireless LAN or wired USB.

2) Referring to Sections 3.5 and 5.3, close the System Startup program and start Setup and Options.

3) Go to the Startup tab (Section 5.3.5) and verify that all existing and new detector(s) are listed. If

any are missing, refer to Section 10 to troubleshoot computer/detector connectivity. If all

detectors are present, go to the Detector Groups tab (Section 5.3.7) and assign them to detector

groups.

4) Return to Section B.8 below to source-test the new detectors.

B.8 Source Test the Detectors

We recommend that you obtain one or more “Exempt Quantity” gamma sources for testing your

equipment. Typically used sources include Co-60, Cs-137, Ba-133, Am-241, or Tl-208 and if you have

neutron detectors in the system which you wish to test you may want to look into purchasing Cf-252

source. Test the system using the “Stand In” survey mode to perform source ID test on the individual

detector and detector groups.


148

B.9 Note: Temporarily Using an Identifier in Standalone Mode

You can optionally remove a standalone identifier (e.g., Detective®- or trans-SPEC series unit) from the

Detective-Remote® system to take a closer look at an object of interest.

• Wireless configurations — To dismount the instrument from the detector array, exit the “Mobile

MCB Server”, then start the desired identifier application.

• When ready to return the identifier to the “Detective-Remote®” system, simply exit the identifier

application, restart “Mobile MCB Server”, remount the unit checking the “Wireless/ActiveSync”

option is still marked on the Mobile MCB Server screen.

• Wired configurations — Disconnect the unit from the USB cable, dismount it from the detector

array, exit the Mobile MCB Server, then start the identifier application

• To return the unit to the “Detective-Remote®” system, exit the identifier application, restart

“Mobile MCB Server”, and remount as “USB Control”, re-cable the unit to the analysis

computer, and make sure the USB Control radio option is still marked on the Mobile MCB Server

screen.

*** Your identifiers are now successfully integrated into the Detective-Remote® system. ***

• Right-click the file, then select Tasks and Back Up... (Figure 105).

• This will open the Back Up Database dialog (Figure 106), which defaults to the correct

export settings (unless they have been changed in a previous work session).

• The Source section of the screen will list the database name. The Backup type is Full, and

the Backup component is Database.

• In the Backup set section, the Name will match the database name.

• The Destination should be Disk, and the default target for the database backup file is:

o C:\Program Files\Microsoft SQL

Server\MSSQL11.MSSQLSERVER\MSSQL\Backup

Note that surveys on Detective-Remote® systems using SQL Server v10 are stored in the

C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL folder (note the

“10" in the folder name). Systems using v11 store surveys in the

...\MSSQL11.MSSQLSERVER... folder, and so on.

8) Figure 108 shows the .BAK file for our example database in the folder C:\Program

Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Backup. Note that its Date

modified is the date and time of export. This file can now be used by anyone with the full suite of

Detective-Remote® software.

9) Restart the System Startup application and the User Interface. The imported survey will now be

available in Review mode, listed in chronological order. If you cannot find it, confirm that you

imported it into the correct \Backup folder.

NOTE: If you review a survey for which the map tiles are not cached on the analysis computer — for

instance, an imported survey or a survey in which you accessed the OSM map in real-time via a cellular

modem — you must connect the computer to the internet and either access the ORTEC® web-based map

server in real time, or pre-cache the surveyed area’s map tiles for offline reviewing. Otherwise, the Map

tab will not display the survey’s map data. If an alternate map system has been loaded on the analysis

computer (computer 2 in a 2 computer setup), no internet connection or pre-caching is required.
