Security Note
This device should not be used in applications where failure may result in death or injury without
proper consideration and design of associated system architecture and redundant safety features.
Connection and repairs are allowed only by a specialist.
When used in a machine or plant, is to ensure that after installation continues to the relevant
provisions, rules and guidelines are complied with!
These products come into contact voltage, therefore to consider the applicable VDE regulations
VDE 0550 / 0551, VDE 0700, VDE 0711, especially VDE 0100 and VDE 0860.

J1 USB Connection USB-B
A suitable cable is included
Power Supply - TB1
USB wiring is very sensitive against EMI errors (mainly sparking when opening contacts). The U-EMI-1 Kit is included with the DIN
rail version and includes two Würth folded cores for the USB data cable and a Ferrite sleeve for the power cable. If you are using
a HUB, it should be protected the connection HUB/computer (U-EMI-2)! The kit includes two Würth folded cores for the USB data
cable.
The cores must be mounted as shown in the illustrations, as close as possible on the connectors.
But also the avoidance of errors is very important. Therefore, the careful layout and installation of the wiring is very important!
Folding core on the USB cable to the computer Folding core on the USB cable to the USB IO
1 or 2 x through the core
Internal power by USB
Do not connect external 5V!
For USB-boards with relays only:
For earlier versions of the Decision-USB IO was also the possibility of the power supply via the USB bus. To get greater stability,
this connection was removed. The USB bus power is not always able to provide enough power for the Relais switched on! The
result is a loss of connection or "hanging" USB module. An external power supply provides a secure power supply!
USB Power Management in Windows - In Window System, USB communication might disconnect under Power Saving Mode or
Sleep Mode. When connecting USB boards on PC, please make sure windows power management set in case interference with
USB communication.

Multiple Boards Connect
When you need to connect more than 3 boards on one PC, please make sure the following below
1. Set di󰀨erent ID for each board.
2. Supply external 5V to each USB board.
3. Supply external 5V to USB hub.
Please make sure your external 5V power supply enough for the USB I/O boards. If input voltage is below 4.8V for USB I/O board,
it can’t work normally and sometimes it will cause device manager keeping refreshing itself or can’t recognize the device.

The JP3 is used to select voltage signal opto+ and opto- range of photo couple input channel 1, and the JP4 is used to select
voltage signal range of photo input channel 2, …etc. When we short the jumper, the input voltage range is 0 to 20V, and open the
jumper means input voltage range is 0 to 30V
Jumper Input Range Inactive Voltage Active Voltage

To test your 16 channel photo isolator input/output card, we
recommend you use loopback circuit shown in below. Where
IA*+ means input channel+ and IA*- means input channel-,
OA*+ means output channel+ and OA*- means output channel-.
* means channel number. Please note that, if you use IA2+, you
must connect its pair IA2- …,otherwise if may short the circuit.
In this experiment, if VCC larger than 10V, then it input HIGH
to input channel, otherwise it input LOW; your program can
get this digital signal easily. If no VCC voltage input, the output
channel will be loopback to input channel, it means when output
HIGH then input channel get HIGH, when output LOW then input
channel get LOW.

USBBootloader.exe is the tool software to update rmware into the USB SerialDevice Board developed by Decision Computer.
When you get a new version of rmware (.hex), you can follow the steps to update rmware to the board.
1. Remove the external input signal Voltage and only support device power.
2. Set Board Id 15 (All on) for Update Mode and press the Reset button.
3. Connect PC to the Board by USB
4. If this is the rst to use this function, please indicate the driver install path to the Driver Folder to install the driver.
5. Open the Software USBBootloader.exe and press the Open button and indicate the hex le and then press the Download button
to update rmware.
6. Set Board Id between 0 ~ 14 and press Reset button and connect PC again.
USB by LAN or Wireless
The remote control of Decision USB products by LAN
or wireless with a remote-PC is very simple with a multi
port USB Server
Because no driver should be installed to the installation
and programming is very easy.
Under Windows, are the external USB I/O directly in the
Device Manager and can be connect or control such as
in the original host PC.
Some unused holes (2 x 5) for JP1 are located on the board. Here a serial port can be added at a special version, with an optional
expansion board, RS-232 or RS-422/RS-485. The ports are controlled via the USB. Please contact us if necessary
Strong electromagnetic sources, such as power lines, large electric motors, switches, or welders can cause strong electromagnetic
interference. Video monitors and cables are strong sources of interference.
If the cable must be led by an area with signicant electromagnetic interference, shielded cables with grounding on the source
should be used.
Avoid placing your cable parallel to a high-voltage line! to minimize adverse e󰀨ects, insert the cable at right angle to the power line.
