The Industrial Raspberry Pi Forum

Hello,

I am getting all green LEDs on the DIO module. I have been able to set the outputs, but I can't seem to get a signal on the inputs.

I have tried jumpering the output O_5 to the input I_5 to see if that works using PiTest. I can see taht the value of O_5 changes to 1, but I do not see the value of I_5 changing when this bit is set.

Any ideas?

Hello,
please measure for safety with a multimeter, you should be able to measure a voltage at output O_5.
