Faceplate

The faceplate provides two HDB44 connectors (J1, J2), one 4-pin Molex connector (J3), and two LEDs:

J1, J2 Connectors

The 32 digital I/O signals are routed to both J1 and J2 connectors. This allows, for example, splitting the input and output signals into two different cables.

If the harnessing uses only one connector, it is recommended to use J2 (bottom one).

The connectors' pin assignment is detailed in the OP8910 Pin assignment
