Hardware pin definition：
There are 4x digital inputs and 4x digital outputs for on/off triggering and status reading.
Digital Input
4 x DI w 2500VDC isolation protection (terminal block)
- Wet contact: Logic: 0~3VDC(max);Logic 1: 10~30VDC
- Dry contact: Logic 0: Shorted to GND; Logic 1: Open (Default)
Digital Output
4 x DO w 2500VDC isolation protection (terminal block)
- Output voltage: 5-30VDC
- Output capability Sink(NPN): 500mA per channel
SW Function
Show DI/DO ports
# #---- Show DI ports ----# # # cd /dev/ # ls DI* DI1 DI2 DI3 DI4 # #---- Show DO ports ----# # # cd /dev/ # ls DO* DO1 DO2 DO3 DO4
Get DI Status
Take DI1 for example
# cat /dev/DI1 1
Note!
1. DI ports have two types : Dry or Wet.
2. For Dry ports
0 means the external circuit is conductive.
1 means the external circuit is NOT conductive.
3. For Wet ports
0 means the voltage of input is between 10-30V
1 means the voltage of input is between 0-3V
3-10V is unstable status.
Set and Get DO Status
Take DO1 for example:（The DO interface of UIO-4033 is of sink type，Default state: No output）
# #---- Set 0 to DO1 ----# # # echo 0 > /dev/DO1 # #---- Set 1 to DO1 ----# # # echo 1 > /dev/DO1 # #---- Get DO1 status ----# # # cat /dev/DO1 1
Note：
Setting 0 to make the external circuit NOT conductive.
Setting 1 to make the external circuit conductive.
