GPIO Connector
Pin 2 of the DC power supply connector is a GPI connector, pin 3 can be set as either a GPI or GPO connector, and pin
4 is a GPO connector. The default trigger source is pin 2 of the DC power supply input connector (GPI1). If connecting
an external device to the GPI or GPO connector, refer to the circuit specifications below.
