2. Product Appearance and Signal Connection

2.1. Product appearance

PS-2000 series DAQ device utilizes metal shield case. It uses plug-in screw terminal connectors to

connect signals. The USB communication interface uses Type-B USB connector. Figure 1 shows its

appearance. The dimensions inside the figure are millimeter.

6

2.2. Signal connection

The screw terminal connector in front of the DAQ device is for connecting the measured

signals.

On the back of the DAQ device, there are two groups of connectors, one USB interface for

connecting with computers directly; the other RS485 interface for connection with computers or

embedded processing system like PLC.

Figure 2 and Diagram 2 show its pin distribution and the corresponding signal in detail.

Name Notes

ch+ ch0+ to ch15+ is the signal positive input of channel 0 to 15

ch- ch0- to ch15- is the signal negative input of channel 0 to 15

5VDC 5VDC power input of RS-485 interface

GND Power ground of RS-485 interface

A+ Positive input of RS-485 communication signal

B- Negative input of RS-485 communication signal

Attention：For models with USB interface, there is no need of extra 5VDC power supply.

3. Installation and Testing

3.1. Driver installation

When PS2016 DAQ device is connected to computers running Microsoft Windows for the first

time, it will require installing the driver before the computer can recognize PS2016 correctly.

Open the folder of "\PS Series DAQ/driver" on the Resources CD, double click the file

"SETUP.EXE", then click "Install", and there will be a dialog of success after the driver is installed.

After correctly installing the driver, Windows Device Manager will recognize PS2016 as a virtual

serial port device under the name of "USB-SERIAL CH341A". The OS will assign a serial port

number for the device as shown in parentheses in Figure 3.

Figure 3、The Device Manager with correctly recognized PS2016

3.2. Software installation

Open the folder "\PS Series DAQ\PS2016 - DAQ Lite Setup\Volume" and run the file "setup.exe".

Set the installation directory for the software, click "Next" all the way till it's installed. Usually you

can keep the default installation directory. Start the software after the installation. Figure 4

shows the software interface.

3.3. Voltage signal test

Connect a voltage signal of a known voltage to the PS2016 data collector, as shown in Figure

5.

Figure 4、PS2016-DAQ Lite software interface

9

Make corresponding settings on PS2016-DAQ Lite, as shown in Figure 6, with detailed notes

below.

1：Select the correct serial port connection.

2：Set the sampling cycle in seconds.

3：Set the range. Can be set as 20V or 200V range when measuring voltage signals.

4：Set the path of data storage.

5：Choose the channel to run the DAQ device in.

Figure 5、Voltage signal test connection

Attention：When measuring voltage signals, if the thermocouple range is

selected by mistake, the PS2016 DAQ device may be damaged after it runs.

Within the data acquisition interface after finishing the settings, click "START" button to

begin the data acquisition and real-time data storage, as showed in Figure 7, with detailed notes

below.

1: Start/Stop button

2: Real time value display.

3: Trend graph display.

4: Corresponding channel legend display.

In the trend graph display, the ordinate scale value is automatically scaled by default. You

can cancel the "automatic Y scale adjustment" by right-clicking the pop-up menu on the ordinate

scale, so as to achieve fixed vertical coordinates. After fixing the ordinate, you can double-click

the ordinate number to modify the ordinate scale value.

The same method can be used to modify the coordinate scale value.

3.4. Temperature signal test

When using PS2016 DAQ device to measure temperature, the thermocouple needs to be

connected to the signal as shown in Figure 8 below.

When using K type thermocouple, the maximum measuring range is 1100℃.

When using other types of thermocouples, the maximum measuring range is the temperature

range corresponding to 45.108mV on its indexing table.

Figure 7、Voltage test acquisition interface

The thermocouple probe must be insulated during the connection. The exposed metal

on the thermocouple probe cannot be connected directly to any voltage signal.

Otherwise, the PS2016 DAQ device may be damaged.

12

You will need to set the range as "thermocouple" in settings, and choose the thermocouple

type you use, as shown in Figure 9, with detailed notes below:

1：Choose correct serial port number

2：Set sampling cycle, measured in seconds.

3：Set range. Choose thermocouple range when measuring temperature and choose

corresponding thermocouple type.

4：Set data storage path.

5：Choose the channel to acquire.

Within the data acquisition interface after finishing the settings, click "START" button to

begin the data acquisition and real-time data storage, as showed in Figure 10, with detailed notes

below.

1: Start/Stop button

2: Real time value display.

3: Trend graph display.

4: Corresponding channel legend display.

In the trend graph display, the ordinate scale value is automatically scaled by default. You

can cancel the "automatic Y scale adjustment" by right-clicking the pop-up menu on the ordinate

scale, so as to achieve fixed vertical coordinates. After fixing the ordinate, you can double-click

the ordinate number to modify the ordinate scale value.

The same method can be used to modify the coordinate scale value.

4. Programming Guide

4.1. Overview

When you need to embed PS2016 into your own measuring and control system, you can

control PS2016 via the SCPI instructions detailed in this chapter.

USB interface

The USB interface on PS2016 DAQ device is virtual serial port. It has a default baud of 9600,

8 bit data bits, 1 stop bit, no hardware handshake and its command uses linefeed "\n" as the end

character, i.e. 0x0A.

RS-485 interface

If your PS2016 DAQ device is equipped with RS-485 interface, it has a default baud of 9600,

8 bit data bits, 1 stop bit, no hardware handshake and its command starts from 1-byte address,

with linefeed "\n" as the end character, i.e. 0x0A. When the address byte is set to 0x00, it

represents the broadcast.

4.2. General commands

*IDN?

Get device information.

*RST

Reset device default settings. This command will disconnect all channels but will not

change the baud setting.

4.3. Setting commands

BPS:9600

Setting serial communication baud as 9600.

BPS:115200

Setting serial communication baud as 9600.

RNG:[n]

16

Set DAQ device range. N can be set as 2, 3, or 9。

When set as 2, it represents the range of 20V; when set as 3, it represents the range of

200V; when set as 9, it represents measuring thermocouple.

ADDR:[n]

Set the address of RS-485 interface. This command is only for models with RS-485

interface. During the setting, there can be only one PS2016 connected to RS-485 bus. Then

the device sends a broadcast address to set its address.

4.4. Measurement commands

CH[n]:V?

Read measured voltage from specified channel with return value measured in V. The value

of n ranges from 0 to 15, corresponding to channel 0 to channel 15.

For example：USB send CH0:V?\n

USB answer 0.01000\n

RS-485 send \00 CH0:V?\n

RS-485 answer \00 0.01000\n

CH[n]:T[TYPE]?

Read measured temperature from specified channel with return value measured in ℃. The

value of n ranges from 0 to 15, corresponding to channel 0 to channel 15.

TYPE can be set as K, J, R, S, B, E, T or N, corresponding to respective type of thermocouple.

For example：USB send CH0:TK?\n

USB answer 25.5678\n

RS-485 send \00 CH0:TK?\n

RS-485 answer \00 25.5678\n
