1 GPI 1
2 GPI 2
3 +5 Volts

GPIs used as inputs are TTL-compatible, pulled up to +5 volts with a 5K resistor.
They should be pulled to ground with a dry switch closure or O.C. transistor to
activate
GPIs used as outputs are open-collector transistors with a 5K pull-up resistor to +5
volts. These transistors pull to ground when the GPI is active. Current should not
exceed 200 Ma.
When ADX-2400 is in Master GPI mode, GPIs 1 and 2 are outputs, and GPIs 3 and
4 are inputs.
