I am trying to use a NI 9481 relay module to turn a light on and off. How can this be done using Daq Assistant? I simply want to program a boolean switch to open and close the circuit.
Start with NI-MAX!
It provides testpanels - and you can easily test your NI9481 to switch a relay.
Afterwards you can create a DAQmx task from your settings and use that task in your VI. I recommend to learn basic DAQmx functions instead of relying on that (dreaded) DAQAssistent ExpressVI!
