Connector Pin-Outs on DIOPU-S PCB
Installing the Direct Inward Dial PCB:
1. Install the DIOPU-S PCB into a slot.
2. Connect the PBXG grounding wire to the PBXG grounding terminal in the cabinet.
The analog DID trunk ports are polarity sensitive (tip to tip, ring to ring). The OPX circuits,
however, are not polarity sensitive. Be sure the wiring is correct for the application.
Once the system is powered up, with normal operation, the status LED will flash fast. If trouble
was found during the self diagnostics routine, the status LED will flash slowly.
3. Tighten the screw on the PCB to secure the card to the cabinet.
