Hi,

I'm trying to output an analog signal on an NI-USB 6009 DAQ device, but I keep getting error 200077 that says "Requested value is not a supported value for this property." Even though I'm wiring a constant (1V) into the write terminal, it's saying I'm inputting 10V (the device can only take 0-5V). Even with input of 0V it gives me the same error. When I use DAQ assistant, though, it works.

I've noticed some posts of a couple people having similar problems, but there's not a good answer. Any help would be appreciated,

Try wiring 0 and 5 constants to the minimum value and maximum value inputs of the DAQmx Create Channel vi.
If this doesn't work you could use the "Generate NI-DAQmx code" feature from the daq assistant by right clicking on the express vi after you've configured it.

Do you use a Scale?

Thanks for the help--it works! I changed the range from 0-5 and it solved the problem.
