Maximum Working Voltage section of the NI 6238/6239 Specifications. Exceeding the
maximum input supply voltage or maximum working voltage of AO signals distorts the
measurement results. Exceeding the maximum input supply voltage or maximum working
voltage rating also can damage the device and the computer. Exceeding the maximum
output voltage can cause injury and harm the user. NI is not liable for any damage or
injuries resulting from such signal connections.

AO Start Trigger Signal
Use the AO Start Trigger (ao/StartTrigger) signal to initiate a waveform
generation. If you do not use triggers, you can begin a generation with a
software command.
