1. Product Overview

1.1. General introduction

Smacq PS-2000 Series data collector is a compact, fully isolated multi-channel testing device

with up to four and a half readings to ensure the accuracy of test data. It is ideal for design

verification, automatic test and data acquisition, aging monitoring and many other test and

measurement applications.

Only one PS-2000 series data collector is needed to start multi-channel test tasks, scaling up

to 500 channels. It can help you start test tasks at very low cost and complete the task with very

high efficiency.

1.2. Product features

up to 4 ½ digit reading resolution，and 0.015% DC voltage accuracy

Max 200V DC voltage range

DC voltage measurement 16 channel full differential input

Only 1 module is needed to start multi-channel testing tasks, with 500-channel

scalability.

Optical isolation between measurement input and computer port

Flexible configuration system. The switch unit can collaborate with third-party test

equipment to set up test system.

SCPI instruction, Visual Studio, LabVIEW and MATLAB development support, convenient

for independent development of automated test system.

USB or RS-485 interface optional

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.

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.

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

Figure 4、PS2016-DAQ Lite software interface

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.
