I can't make NI DAQ AO1 send signals

[farahikia83]

I have developed a program in LabVIEW to send a trigger signal to a camera. Initially, I had used AO0 of the DAQ to trigger the camera and it works fine. Now, I just try to use AO1 instead (by simply modifying the code) and it won't trigger the camera. Switching back to AO0 works again. And as of now, I am not using two outputs simultaneously. Next step will be to wait for an input, perhaps in AI0, to generate output in AO1.

I'd appreciate any thoughts on this.

There isn't a lot to go off of here. I would check to make sure your connections are correct and that you have the correct channel specified throughout your porgram. I would also check to see if you can get a signal on AO1 in MAX testpanels to eliminate it being your code.

You have to wire AO1 to the trigger.  Simply changing the code will not do the job.

I found the problem. It may sound dumb, but I wasn't paying attention that as I was modifying the code it was switching to device2, but I was still using device1 to trigger the cameras.

I'm aware of wiring principle!
