SAFETY SUMMARY The following general safety precautions must be observed during all phases of operation, service and repair of this equipment. Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture and intended use of the equipment

Thrane & Thrane A/S assume no liability for the customers failure to comply with these requirements.

MICROWAVE RADIATION HAZARDS During transmission this unit radiates microwaves from the antenna. This radiation may be hazardous to humans if they are exposed to it directly at short distances from the antenna. During transmission, make sure that nobody is closer than the recommended minimum safety distance of 0.3 meter.

KEEP AWAY FROM LIVE CIRCUITS Operating personnel must not remove equipment covers. Qualified maintenance personnel must make component replacement and internal adjustment. Under certain conditions, dangerous voltages may exist even with the power cable removed. To avoid injuries, always disconnect power and discharge circuits before touching them.

The STX and ETX characters are used by the TT-3606E, TT-3606C and TT-10202A software to identify certain important information.

1.4 THE INTERFACE The transceiver provides a text-based interface on its serial communications port. The default settings for the serial port are:

4800 baud No parity 8 databits 1 stopbit

See the command SET -c Show or Set Serial Port Parameters for an explanation on how to change these settings.

The concept of the interface is to treat the transceiver as a message mailbox. There are commands to transfer files to and from the transceiver and commands to control the satellite link. When the transceiver issues the colon : prompt, just type in the desired command.

A typical example of a command description is:

ncs -r where "ncs" is the command name, "-r" is the option switch and "" is the parameter value that should be supplied.

Short forms are available for most commands; usually they are the first two letters of the full command name. To find the short form of a specific command, see the Command Reference chapter. The commands are not case-sensitive.

The prompt sequence from the Transceiver is in this notation:

:a

Note that there is a space character after the colon character.

Introduction 15 Abbreviations


The results of the commands are returned in INFO or ERROR messages. By default, these messages are not displayed but stored in a log, which can be accessed using the STATUS -l Show Status Report command. This is called silent mode. Silent mode can be turned off using the command SET -r Silent Mode. When silent mode is off, all INFO and ERROR messages will be printed directly to the console. A list of messages can be found in the chapter Info and Error Messages.

1.5 CHANGES FROM TT-302X C-TRANSCEIVER

1.5.1 ENVIRONMENT VARIABLES

Only two environment variable is fully implemented in the TT-3026L:

TZ, time zone PRNFILTER, disable log or status printing

Use PRNFILTER=LOGS to disable printing of Rx, Tx and EGC logs, PRNFILTER=STAT to disable printing of INFO and ERROR messages or PRNFILTER=LOGS,STAT to disable both.

A number of variables are partly implemented for backward compatibility reasons. The values of these variables are set to default at power-on. The following lists environment variables that are preset at power ON:

1: POSFORMAT=PU 2: PRINTER=NO 3: PPAGING=NO 4: PLINES=61 5: FFEED=NO 6: OCEANSHIFT=SIGNAL 7: PCHARS=80 8: PCUTLN=NO These variables cannot be changed. All other environment variables are lost on power down.

1.6 THE CAPLIB SOFTWARE PACKAGE The CapLib is a C source code package which can be used to create a communications application that uses the Inmarsat-C system and a Thrane & Thrane Transceiver on a DOS, Windows 95, Windows 98, NT or Windows CE platform.

Please refer to TT 99-104209, CAPLIB - Communication Library

Introduction 16 Changes From TT-302x C-Transceiver


2 GENERAL TRANSCEIVER PROPERTIES 2.1 AUTOMATIC OPERATIONS

The Transceiver has the following automatic operations built in:

Operation Mobile Type

Read Navigational data from internal GPS L/M/S/D/LM, TT-3000SSA and TT-3000E

Check Bulletin Board Error Rate (BBER) every 8.64 seconds. At a

BBER of 80 an info is generated and a scanning will begin.

L/M/S/D/LM, TT-3000SSA and TT-3000E

Automatic spotbeam scanning every 24 hours. L/M/S/D/LM, TT-3000SSA and TT-3000E

Requesting data and/or sending position information at regular

intervals.


Clean-up of the logs when needed. L/M/S/D/LM, TT-3000SSA and TT-3000E

Network version check every 24 hours. If the Network version

stored in the Transceiver's LES table, is different from the NCS

TDM's, a login will commence.


Clean-up of the file system when needed. L/M/S/D/LM, TT-3000SSA and TT-3000E

If a tuning operation in a protocol fails, the Transceiver will

check the LES Network version number against the NCS TDM

Network version, and if they differ a login will be issued.


Automatic correction of Transceiver CMOS clock time when

deviation to the GPS UTC reaches 10 sec.


Table 2.1 Automatic Operations

2.1.1 POWER ON OPERATION

The Transceiver will perform the following operations when turned on.

LOGIN IF NECESSARY

By default the transceiver will login at the current ocean region if logged-out. This default setting can be changed so that the transceiver login on the ocean region with the nearest satellite (See the command SET -ns).

If using login on nearest satellite: The transceiver use the last known position to decide which ocean region to use. Only allowed ocean regions are considered when deciding which ocean region to use (See 2.1.2 ).

If the login for some reason fail the transceiver will try to find another ocean region.

STORE INFORMATION

The time and date of power-on, login and logout are stored.

2.1.2 AUTOMATIC OCEAN REGION SHIFT

This feature is very useful when the vessel/vehicle operates in different ocean regions.

The transceiver will perform automatic scanning and ocean region shift, if the signal strength has been bad for a few minutes or at 24 hours interval. The ocean region shift can be disabled or restricted to one or more allowed regions (See below and the se -o command).

General Transceiver Properties 17 Automatic Operations


The environment variable OCEANSHIFT is for backward compatibility only.

AUTOMATIC OCEAN REGION SHIFT

Preferred ocean setting Allowed ocean(s) setting Automatic ocean-region shift

behavior

Allowed ocean set to "NONE" Scanning current ocean region,

and login on the strongest spot.

If synchronizing to current ocean

region fails the other regions are

scanned.

Preferred ocean set to "NONE"

Allowed ocean set to one or more

oceans (W, E, P and I)

Scanning current ocean region,


If synchronizing to current ocean

region fails the allowed regions are

scanned.

Preferred ocean set to an ocean

(W, E, P or I)

Allowed oceans setting has no

effect.

Scanning preferred ocean region,


If synchronizing to the preferred

ocean region fails info is sent to the

operator. The transceiver will be

tuned to preferred ocean

Automatic ocean shift does not apply for the TT-3000E mini-C GMDSS System - ocean shift must be initiated by operator.

2.1.3 AUTOMATIC LOGIN

The Transceiver will start an automatic login under the following circumstances:

When a scan command finds a different NCS with a stronger signal than the current NCS. The transceiver will login to the new NCS. If this fails, it will return to the original NCS.

Every 24 hours the transceiver will check if the Network Version Number of the stored LES Table and the NCS TDM channel are different. If they are different the transceiver will login again on the current NCS TDM to get a new LES Network Table.

If a tuning operation during a protocol failed the transceiver will check if the Network Version Number of the stored LES Table and the NCS TDM channel are different. If they are the transceiver will login again on the current NCS TDM to get a new LES Network Table.

When the transceiver is turned on it will start a login to the current NCS TDM if it's status shows that it is not logged in.

The transceiver will make an automatic login to a new NCS if the Inmarsat-C signal has been bad for a few minutes (does not apply to the TT-3000E mini-C GMDSS System).

2.2 AUTHORITY LEVELS Many commands and features in the transceiver require that the user be at a certain authority level. This system exists in order to allow system administrators of various sorts to configure the transceiver with settings, which the normal users cannot change.

General Transceiver Properties 18 Authority Levels


Authority level protection also prevents users from inadvertently changing settings, which may interfere with the correct operation of the transceiver.

A user can acquire a specific authority level using the SU command (see page 143). The user supplies the desired level and the password for that level. Users can change the password for each level, provided that they are at a sufficient authority level. The levels are:

User Name Default Password Description

Normal (empty) Normal user level. This authority

level is the default after boot-up.

Super Super Super user level.

Sysadm sysadm System administrator level.

Intended for system

administrators

At a given authority level, the user has access to all the features at that level in addition to those at the lower levels.

Every command can be assigned a required authority level if it is necessary to reduce the set of commands that are available to users at lower authority levels. A user can set the required authority level to his/her own level or lower.

Authority levels also affect Data Network IDs (DNIDs), interval programs and event programs. Each DNID is given an authority level. Access at this level is required to modify the properties of the DNID and the programs that are associated with it. See also Data Reporting on page 29.

All users except "normal user" are required to change their password the first time they use the SU command.

2.3 FILE SYSTEM The file-system and all files are stored in non-volatile RAM.

The files system has the following specification/characteristic (as of [ver. 2.12]):

Total allocated memory for RAM-disk: 179.200 bytes Max. file creation: 1400 files. Maximum open files: 16 Internal use of file-priority. Terminal command supporting transferring/creating, deleting, typing and listing

files.

General Transceiver Properties 19 File System


2.3.1 FILE PRIORITIES

The file-system operates with the following internal priorities, which cannot be altered by normal users:

Priority Description File naming

Highest

System data-setup files

ZoneFile.Dat, DnidStr.Dat,

Datarep.dat

System log files

_EGCLOG, _TXLOG, _RXLOG

and ERROR.LOG.

Poll files POLL.xxx

Incoming messages/files IN.xxx

EGC messages/files EGC.xxx

Lowest User files *.*

These priorities are mainly used in two situations:

When deleting files. (Note: a normal user cannot delete system files). When creating or extending files. If no memory is left for creation or extension of a

file, an internal mechanism automatically tries to release memory from the oldest files that have a priority lower than or the same as the new file.

2.3.2 FILE COMMANDS

The terminal interface provides the following commands for file operations. See the Command Reference chapter for details about each command.

DIRirectory / LS. Displays a list of files. TYpe. Displays the contents of file(s). TRansfer. Transfers a file from the console to the RAM-disk. DELete/RM. Deletes one or more files. SENDFILE/SF. Sends a file using the X-modem protocol. RECVFILE / RF. Receives a file using the X-modem protocol.

2.4 SLEEP MODE (POWER EVENTS) The power controlling of the transceiver always follows one of three protocols.

Sleep Mode Disabled. (Default configuration) Sleep Mode Enabled with or without Interval and fixed time wakeup.

2.4.1 SLEEP MODE DISABLED

If Sleep mode is disabled configured as SL -c then

If the transceiver is switched off, the transceiver will indicate this by sending "Power Down Report" and "Power Up Report" when supply power has been re-established. The "Power Down Report" includes the last known position before the power was removed. The "Power Up Report" includes the current position.

General Transceiver Properties 20 Sleep Mode (Power Events)


Note, when sleep mode is disabled, either through the terminal of via. poll, a leave sleep mode report is sent.

2.4.2 SLEEP MODE ENABLED

The sleep mode enabled can be configured with or without Interval and fixed time wakeup.

Sleep mode is configured without wakeup using SL -i 0,0,0,0.

This configuration is used when it is necessary to separate "supply power removed abruptly" from " supply power switched off nicely".

If the supply power is removed abruptly then the transceiver will indicate this by sending "Power Down Report" and "Power Up Report" when supply power has been re-established. The "Power Down Report" includes the last known position before the power was removed. The "Power Up Report" includes the current position.

If the supply power is removed using the remote switch then the transceiver will indicate this by sending an "Enter Sleep Mode Report", before the power is switched off and "Leave Sleep Mode Report" when transceiver is switched on again. The "Enter Sleep Mode Report" includes position at the time of transceiver is switched off. The " Leave Sleep Mode Report" includes position at the time of transceiver is switched on again.

Sleep mode is configured with wakeup using SL -i x,x,x,x,x (x is any value, except from all 0).

This allows the transceiver to save power/battery and periodically wakeup in interval of 1-24 hours and transmit data-report etc. The transceiver always automatically turns off the power, after transmission of the last data-report.

The configurations also setup the transceiver to wakeup every 24 hours at a fixed time for a fixed period of time (from 15 to 60 minutes). During this fixed time wakeup, the transceiver can be reconfigured, receive messages etc.

2.5 I/O INTERFACE The transceiver contains an IO-interface of six In/Out open collector pins. If the transceiver is part of a 3026D system pins 1,2,5 and 6 will be reserved for this purpose (see paragraph 6.2 ). If the transceiver is part of a SSA system all six pins will be reserved for this purpose (see paragraph 6.2 ). For the TT-3000E mini-C GMDSS System pin 1,2,3 and 4 are reserved. Otherwise only the first pin is reserved for Land Mobile Alert (see paragraph 6.1 ) and the remaining five are available for any user-purpose. (See Ref. [3] TT 98-116078, TT-3026L/M Installation Manual).

Before use, the io-pins must be configured using the IO command as described in paragraph 8.17 IO

When using the Zone Group/Group list Selection Poll (see paragraph 5.3.2 ) for changing output status, make sure to configure the io-pins as output. Poll for reading I/O status is possible for all io-pins at any time.

General Transceiver Properties 21 I/O Interface


2.5.1 INPUT PINS

Any io-pin can be configured to generate any of the T&T predefined internal event, using the "IO -i ..." command, as described in paragraph 8.17.2 .

Example: "IO -i 2,0,1,2" configures pin 2 to generate an internal event causing the transceiver to change between long and short reporting interval.

Configuring short and long reporting interval is described in paragraph 8.23.5 PG -e Extended program set-up and 8.23.12 PG -l Set Long Interval and Minimum Distance.

2.5.2 TACHOGRAPH INTERFACE PIN

One user selectable io-pin can be configured to function as a tachograph interface input pin.

A tachograph is a unit that keeps track of the speed and motion of a vehicle. Connecting a tachograph to the transceiver (normally through a suitable interface converter) will make it possible to gather statistics of driven speeds and distances.

The main function of the tachograph interface is to count transitions (edges) on the incoming signal; both positive edges (going from low to high input level) and negative edges (going from high to low input level) are counted. The maximum input frequency is 1.0 Hz (giving 2 edges per second).

Beside distance registration, the tachograph support function detects periods where the vehicle is stopped or parked. This information can be included in reports (see sections 4.2 and 8.9.4 ), control the transmission of reports (see sections 4.4.2 and 8.23.5 ) and control the data-logging function (see sections 7 and 8.20 )

This interface is configured through the IO -t command as described in paragraph 8.17.5 .

2.5.3 OUTPUT PINS

Output pin can be configured to change on any of the T&T predefined internal event using the "IO -o ..." command as described in paragraph 8.17.3 IO -oOutput-pin setup.

Examples:

1. "IO -o 3,0,1,2" configures pin 3 to change level, when receiving Enter/Leave Zone events. General configuration of zones etc, see paragraph 4.11 Surveillance zones.

2. "IO -o 4,0,8,7" configures pin 4 to change level, when receiving Above/Below Speed Limit events. General configuration of speed limit etc, see paragraph 4.8 Speed Limit Event.

3. "IO -o 4,0,5,6" configures pin 4 to change level, when receiving GPS Blocked /Unblocked events, See paragraph 4.7.3 GPS Blocked Events.

4. IO -o 5,0,1,9 configures pin 5 to go low when a zone is entered and to go high on a Change Output A event. The latter is a way of making an output pin respond to an input pin by programming an input pin to generate this specific event (e.g., the command IO -I 2,0,3,0: Generate Change Output A when pin 2 goes low).

General Transceiver Properties 22 I/O Interface


As can be seen in examples 2 and 3, several (up to 16) events can be assigned for a single out-pin

2.6 GPS UNIT The transceiver has a built-in GPS receiver that provides the current time and position. The GPS receiver works by receiving timing signals from the GPS satellites. With later versions (2.21 or later) it has become possible also to receive SBAS signals.

2.6.1 SBAS

SBAS is originally created for aviation control purposes and the advantage of having this augmentation is two-fold:

Atmospherical correction that generally makes it possible to obtain greater precision.

Integrity monitoring that increases the reliability of the GPS system by disregarding faulty or imprecise signals.

Dispite the primary purpose being aviation, other GPS applications may also benefit from the SBAS service.

There are a number of SBAS systems each covering different geographical areas.

WAAS in North America. EGNOS in Europe and Africa MSAS in Asia and Australia

At the time of writing only WAAS is fully functional; the other systems are under development.

Unlike the normal GPS signals, the SBAS signals are broadcast through geostationary satellites that are identified with PRN numbers in the range 100 to 132. The GPS receiver in the TT-3026 is capable of choosing an SBAS PRN itself, but that is not recommended for normal use. If, e.g., a WAAS signal is used in Europe, the advantage is questionable at best since Europe is outside the coverage area of WAAS (though not necessarily outside reach of the WAAS signal). The GPS receiver is not able to detect this from the received signals and therefore it is generally required to choose the SBAS PRN manually.

Please note that PRN allocation is subject to change, particularly for the systems not yet in full operation.

Furthermore, systems may send the augmentation information as test messages (type 0 messages). Generally test messages should not be used since there is no guarantee of the quality or availability. However for test or evaluation purposes the TT-3026 may be configured to accept test messages.

Updated information on SBAS PRNs and test transmissions is provided by these organisations:

The European Space Agency (for EGNOS) The Federal Aviation Administration (for WAAS).

General Transceiver Properties 24 GPS unit


3 MESSAGING 3.1 OVERVIEW

Sending a message with the transceiver involves two steps.

1. Transfer a file containing the message to the transceiver using the "tr" command

2. Transmitting the file using the "tx" command

When a message transmission is initiated, the transmit-log is updated. Since the log and the transmitted file are preserved after a reboot, the transceiver can send the message after a reboot.

3.2 FILE FORMAT Depending on the destination the file may, apart from the message itself, contain the destination addresses. In the following the address format for the supported destination are described. Multiple address lines of the same type (e.g. PSTN) can be specified. After the address information, an empty line must be inserted.

3.2.1 TELEX ADDRESS

The file shall contain the address information at the beginning of the file. Telex addresses are defined in the ITU-T U.80 recommendation and have the general format.

[suffix]

Currently only the following suffixes are recognized.

1. Detection of expected destination answer-back as specified with the '/' switch

2. Attention line information, which might be added to the message header, as specified within parentheses

3. Request for message delivery acknowledgement as specified with the 'ACK' switch

4. Delayed delivery request as specified with the ',Dxx' switch

5. Time limited delivery as specified with the ',Lxx' switch

In connection with (1) it should be noted, that answer-back checks are not applicable for MES to MES calls.

3.2.2 PUBLIC SWITCHED TELEPHONE NETWORK (PSTN) ADDRESS

The file shall contain the address information at the beginning of the file.

Messaging 25 Overview


3.2.3 PUBLIC SWITCHED DATA NETWORK (PSDN ) X.25 ADDRESS

The file shall contain the address information at the beginning of the file.

3.2.4 CLOSED DATA NETWORK ID (DNID) ADDRESS

The file contains no address information. DNID specified at the command line.

3.2.5 SPECIAL ACCESS CODE (SAC) ADDRESS

The file shall contain the address information. The address format depends on the service and the LES configuration, contact the LES operator for details. The special access code addressing is selceted with the -t 6 option and the SAC is specified at the command line with the -e NN option.

Examples of sending email using the SAC below.

3.2.6 ADDRESS PREFIX

The Telex, PSTN and PSDN addresses may be prefixed with a two-digit prefix. The prefixed store and forward service must be used.

3.3 MESSAGE ALPHABETS Messages can be transmitted using a 5-bit or a 7-bit alphabet or 8-bit data. Alphabet or data can be selected with the "-l" option of the "tx" command. When a message is transmitted the transceiver assumes that the file is in ASCII format and will convert the message to the selected 5 or 7-bit alphabet. If 8-bit data is selected no conversion are performed.

The 5-bit alphabet (ITA2) defined in ITU-T S.1 with some Thrane & Thrane additions consist of the following characters.

the 26 Latin alphabetic characters: a b c d e f g h i j k l m n o p q r s t u v w x y z decimal figures: 0 1 2 3 4 5 6 7 8 9 Punctuation marks and miscellaneous signs: . , : ? + - / = ( ) Thrane & Thrane additions: $ # @ % Other characters will be converted to: ?

The 7-bit alphabet (IA5) defined in ITU-T T.50. Removing the most significant bit does conversion to this alphabet from ASCII.

3.6 DNID DOWNLOAD CONFIRMATION [2.14]

This is a special message that may be delivered in a DNID mailbox indicating that the issuing transceiver has had the DNID inserted and activated. The format of the message is found in appendix G . After delivering the activation message the DNID can be used just like a DNID downloaded with a poll (see Remote Configuration and Polling, Chapter 5 ).

Note that only some transceivers can send this message; it only applies to transceivers that have a special factory configuration and are put into use according to a special agreement with a LES.
