UIO-4033 & UIO-4035 both have eight DI ports and eight DO ports.

Show DI/DO Ports

List DI/DO supported ports:

Show DI/DO Ports

# #---- Show DI ports ----# #
# cd /dev/
# ls DI*
DI1 DI2 DI3 DI4 DI5 DI6 DI7 DI8

# #---- Show DO ports ----# #
# cd /dev/
# ls DO*
DO1 DO2 DO3 DO4 DO5 DO6 DO7 DO8

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）

# #---- Set 0 to DO1 ----# #
# echo 0 > /dev/DO1

# #---- Set 1 to DO1 ----# #
# echo 1 > /dev/DO1

# #---- Get DO1 status ----# #
# cat /dev/DO1
1

The wiring and measurement methods can be referred to as shown in the following diagram.

Note：There are no specific requirements for the power supply. Just make sure it is within the product POR specification of 5 to 30V DC (and ensure that the overshoot at the moment of power-on does not exceed 30V of the POR). Please be sure to confirm the overshoot at power-on of the POWER Supply being used.
