constant analog output

[phil_knox]

This has to be simple task, but I seem to be missing something.

I would like to generate a constant voltage on one of the AO channels (the output goes to a fan controller that controls fan speed). How do I generate a constant voltage on the AO channel? I've looked at the examples and they all generate waveforms (sine, square, etc.). I'll update/modify this voltage perodically based on temperaturements I'm taking (over serial communication, not via the DAQ). I suspect I'll update the voltage every minute or so.

Sorry about asking such a simple question, but I've looked at the examples and don't quite understand.

thanks in advance,
phil

Hi Phil,
Check out the GenVoltageUpdate example under ProgramFiles...DAqmx\Examples\Analog Out\Generate Voltage\GenVoltageUpdate\
This generates a single voltage value every time you click on the Start/Generate button. You could probably use this example as a starting point.
Hope this helps...

Thank you very much. I was looking at the wrong examples.
