I have a PXI-7951 and NI 6583. The single-ended digital outputs are defaulting to 3.63 volts. I am using the I/O nodes Set_Voltage_DAC, Voltage_DAC, and Set_Voltage_Done, to set the output to 3.0 volts.
1. Set_Voltage_DAC = False
2. Voltage_DAC = 234 ( per the Guide: 3.63V - (234 * -0.00269) = 3.0V)
3. Set_Voltage_DAC = True
4. Wait for Set_Voltage_Done to become True
This doesn't seem to work. The outputs are still 3.6V.
Anybody have any hints on how to do this correctly?

Have you tried using another CLIP for your device? You might have selected one with logic output voltage.
