MM4005 Appendix C — Connector Pinouts
C.5 GPIO Connector (37-Pin D-Sub)
This connector is dedicated to the digital I/O ports.
All outputs are open-collector type and are rated for maximum 30V and
40mA (Fig. C.2). To drive a logic input, they require a pull-up resistor.
All inputs are optocoupled and are configured as a LED in series with a
1kΩ resistor connected to the +12 V line (Fig. C.2).

1)
If optocoupling feature is activated, pin 1 outputs +12Vdc. Needs factory
service to change.
2)
If optocoupling feature is activated, pin is for external ground. Needs
factory service to change.
