Hi,
When I try to output different voltages from two different output channels on the card, I end up getting Error -200077 errorInvalidAttributeValue for the second channel I try to output to. The result is no output. To intialize the channels ("Dev1/ao0" and "Dev1/ao1"), I run the DAQmxCreateAOVoltageChan function assigning 0 and 1 as the task handle. At this point, no errors have been thrown yet. I suspect the error gets thrown when I run DAQmxWriteAnalogF64 to write the voltage to the channel. This problem only happens to the second channel I try to write to. There is no error when I only initialize and run a single channel.
Does anybody know what exactly the error means? What really stumps me is that I swapped the hardware into this computer from another, and it all worked when I tested it on the earlier computer.
If any more information is needed, I can provide it.
