I would like to recognize via a DI and a DO channel, if a contact is switched or not.
For this I want to set the DO channel high (+ 5V) and wire this to the DI channel via a switch. Then I read out the status on the DI.
I use a DAQ USB-6000 for this and the nicaiu.dll. I allready managed to read out a logical value on the DI channel. But I can't get a high signal at the DO port.
Many thanks in advance.
It would be helpful if you could post the code for us to review and guide you better.
