Description
MOTOROLA (EMERSON) IPMC761 PMC Multi‑Function I/O Mezzanine Card
Former Motorola Computer Group, later acquired by Emerson; single‑width PMC mezzanine I/O board, for MVME5100 / MVME5500 VME single‑board computer; provides legacy I/O backward compatibility with older MVME761 transition rear‑panel board。

Product Overview
IPMC761 is PMC‑form‑factor multi‑function I/O daughter‑board for Motorola‑Emerson VME SBC series. It adds SCSI storage, parallel port and multi‑port serial interfaces to MVME5100/MVME5500 host board. It is designed for backward compatibility with legacy MVME2600 / MVME2700 system I/O wiring via MVME761 rear transition module, avoiding full‑system rewiring during hardware upgrade projects.
Important notes:
- Cannot work standalone; must plug into PMC slot of compatible VME single‑board computer.
- Requires host SBC jumper set to IPMC mode; otherwise rear‑I/O signals will not route to MVME761 transition boardManualsLib.
- Distinction: IPMC712 = RS‑232 only serial version; IPMC761 = SCSI + parallel + mixed sync/async serial full‑feature version.
- End‑of‑life legacy VME embedded component, only spare‑part supply.
Application Scenarios
- VME‑bus embedded control system: Industrial, aerospace, accelerator control, test‑stand single‑board computer I/O expansion
- Legacy MVME platform upgrade: Retain existing rear‑panel wiring by using IPMC761 + MVME761 transition module
- Industrial test‑equipment, data‑acquisition racks with SCSI storage and multi‑serial‑port requirement
- Retrofit & spare‑part replacement for MVME5100 / MVME5500 VME systems
