Troubleshooting DAQNavi Device Drivers Error
Driver functions return a status code when called to perform a certain task for an
application. When a function returns a code that is not zero, this means the driver has
failed to perform the designated function. To troubleshoot device driver errors, check
the error code and error description in the Error Control section for each function in
the DAQNavi SDK manual.
