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

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.

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.

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.

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.
