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.

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!

Ferrite sleeve on the power supply cable
The power-supply of our products must be 5V external DC. It is to pay attention to correct polarity. Otherwise, the product could be
damaged. If the board is by wrong power supply except function, you can try new store the rmware.
The U-EMI-1 Kit is included with the DIN rail version, and includes ferrite sleeve, shielded by EMI for the power cable. Are shown
on the image above.
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.
More than 5.2V can kill the CPU!

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.

ISOLATOR Input SET JP3 to JP18
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
short 0 to 30V 0 to 1.5V 3 to 20V
open 0 to 20V 0 to 16.5V 18 to 30V
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.

Digital Input / Output Port Setting
After setting by the software, the setting of JP9 and JP10 must match the
setting, or it could be dangerous. Especially in setting ports as output, it must
open the jump on the board, or it may cause main IC damaged.
Please use this function extremely carefully.
UHRO-8 provide 16 digital channels (TTL level) and allow user to set them as 8 channel input port or 8 channel output port. Default
setting is both of the ports as input
When user needs to change the port setting, it must be set in both software and hardware. In software setting, USB Init Tool.exe
is a setting tool for USB series products. User can nd it in Decision Studio CD with its manual. In hardware setting, JP9 and JP10
on the board are used to select input/output of digital I/O. When shorting JP9 means setting DIO_00 to DIO_07 as input mode,
otherwise opening JP9 means setting DIO_00 to DIO_07 as output mode. When shorting JP10 means setting DIO_08 to DIO_15
as input mode, otherwise opening JP10 means setting DIO_08 to DIO_15 as output mode.

Contact protection circuits
When a reed relay is used with an electromagnetic relay or solenoid, the energy stored will cause an inverse voltage when the
reed contacts break. The voltage, although dependent on the inductance value, sometimes reaches as high as several hundred
volts and becomes a major factor to deteriorate the contacts.
• DC: Protection circuit with a diode
• DC and AC: Protection circuit with Varistor or RC-element
The suppressor must be made to the load.

Firmware Update Manual
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.
Communication JP1 - only option!
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
The module is not recognized - troubleshooting
Should the USB module is no longer found by the computer's operating system, usually helps new plug or to change the USB port.
Can be also an unstable power supply. A switching power supply with su󰀩cient reserve should be used
Should the previous notes remedy not usually it helps to replace the rmware!
