Description
Motorola IPMC761-001 | Multifunction Rear-I/O PMC Module
Product Introduction
When maintaining a legacy MVME installation, the rear-I/O module is not a generic accessory. It is part of the system’s interface architecture. The Motorola IPMC761-001 is a multifunction rear-I/O PMC module designed for compatible Motorola Computer Group embedded computing platforms.
The IPMC761-001 provides 8-bit SCSI, parallel, and serial I/O capabilities, including two asynchronous serial ports and two synchronous/asynchronous serial ports. It is intended for use with a compatible host and transition-module arrangement—not as a standalone PLC or general-purpose controller. For maintenance and obsolescence planning, verify the complete part number, host-board compatibility, and required rear-I/O hardware before substituting this module.

Global Sourcing & Live-Test SOP
For legacy Motorola hardware, model verification and documented inspection are essential to avoid receiving a similar-looking but incompatible board.
Incoming Verification
- Confirm the IPMC761-001 model marking on the physical board.
- Photograph the PCB, connector layout, labels, and revision identifiers.
- Inspect PMC contacts for bent pins, oxidation, or physical damage.
- Check for corrosion, cracked components, and evidence of unauthorized repair.
Authenticity and Configuration Review
- Compare the PCB layout and markings against available OEM documentation.
- Record serial numbers and board revisions where present.
- Confirm the intended MVME host and transition-module configuration.
- Identify any missing brackets, cables, or related hardware before listing or shipment.
Functional Validation
- Install only in a compatible host system using the applicable OEM procedure.
- Verify host recognition and available startup diagnostics.
- Test supported serial, parallel, and SCSI interfaces using suitable equipment.
- Record the host model, test setup, observed results, and any limitations.
- Document extended testing only when it has actually been performed.
ESD Packaging and Shipment
- Handle the module using ESD-safe procedures.
- Protect the PMC connector and exposed components during transit.
- Secure the board in ESD-safe packaging with adequate mechanical protection.
- Include only accessories explicitly identified in the sale.
Field Engineer’s Pitfall Guide
- ❗ Do nuse with related IPMC variants.The has a documented 8-bit SCSI and specific serial/parallel I/O configuration. Confirm the complete part number before ordering a replacement.
- ❗ Verify the host and transition module. is not a universal PMC I/O card. Confirm compatibility with the installed MVME board and the required MVME761 transition hardware.
- ❗ Do not assume the module is plug-and-play. System configuration, cabling, serial-interface requirements, and host operating mode can affect commissioning. Follow the applicable OEM installation documentation.
Intent-Driven FAQ
Q1: What is thola ?
It is a multifunction rear-I/O PMC module for compatible Motorola MVME embedded computing systems.
Q2: What interfacethe provide?
Documentation identifies 8-bit SCSI, one parallel port, two asynchronous serial ports, and two synchronous/asynchronous serial ports.
the a standalone PLC?
No. It is a rear-I/O module designed to work with a compatible MVME host system.
Q4the include an MVME761 transition module?
Not necessarily. The transition module and associated cabling should be considered separate unless the seller explicitly lists them as included.
Q5:use to replace an ?
The is a documented model IPMC761 family, but verify the existing board’s complete part number, host compatibility, and I/O configuration before substitution.
the hot-swappable?
Do not assume hot-swap support. Follow the host system’s OEM power-down and installation procedures.
Q7: What should I verify before purchasinglus ?
Confirm the physical model marking, board revision, condition, required transition hardware, and compatibility with the target MVME system. Request test evidence if operational condition is a purchase requirement.
