This should be simple, but I'm stumped. I simply need to control the output of A NI 9265 4 mA to 20mA with a slide pointer. One pointer alone works great and I can control the output of AO0. Since I have two proportional valves, I simply added another identical channel (AO1) to the 9265 DAQ, added a merge signals wiring connection, and added an identical slide pointer. Then I get error 200561 :"Attempted writing analog data that is too large or too small..." Both channels and inputs are set up the same way. I even placed another DAQ assistant using AO1 and an identical vertical slide pointer. Same error 200561. What am I missing here?
