AO External Start Trigger Input *1 External trigger input for starting analog output sampling.
AO External Stop Trigger Input *1 External trigger input for stopping analog output sampling.
AO External Sampling Clock Input *1 External sampling clock input for analog output.
Digital Input00 - Digital Input03 Digital input signal.
Digital Output00 - Digital Output03 Digital output signal.
Counter Gate Control Input Gate control input signal for counter.
Counter Up Clock Input Count-up clock input signal for counter.
Counter Count-up Pulse Output Counter output signal.
Digital Ground *1 Common digital ground for digital I/O signals, external trigger inputs,
external sampling clock inputs, and counter I/O signals.
Reserved (Counter Input) Reserved pin.
N.C. No connection to this pin.
*1 : Pin Assignments is different from High-Resolution Analog Output Board for Low Profile PCI DA16-4 (LPCI)L.
- Do not connect any of the outputs and power outputs to the analog or digital ground. Neither
connect outputs to each other. Doing either can result in a fault.
- If analog and digital ground are shorted together, noise on the digital signals may affect the analog
signals. Accordingly, analog and digital ground should be separated.
- Leave "Reserved" pins unconnected. Connecting these pins may cause a fault in the board.
