OP8940 Hardware Interface
- Sylvain Ménard
Face plate
The face plate provides two HDB44 connectors (J1, J2), one 4-pin Molex connector (J3) and two LEDs:
J1, J2 Connectors
The 32 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 OP8940 Pin assignment
