Issue Details

When using DAQmxWriteAnalogF64 in my C-based application, I'm getting the error -200077 DAQmxErrorInvalidAttributeValue. This code worked previously with my older card but not after I upgraded to a drop-in replacement. 

Solution

This error occurs when any of the parameters in the Analog Output/DAQmx Write are incorrect. Double check all the parameters with the device specifications sheet in order to ensure the correct values are being used. Sometimes when upgrading hardware, the new device may have slightly different specifications, even when it's considered a drop-in replacement.
