MOTOROLA MVME712M6E

• Cooling Requirements:
  • Requires forced-air cooling
  • Minimum recommended airflow: 5 CFM (cubic feet per minute)
  • Validated under high-load and high-density thermal conditions
• Compliance: Meets FCC Class A emission standards when installed in a properly grounded conductive enclosure using shielded cables and secured mounting hardware

Key Features

• Serial Communication Ports:
  • Four EIA-232-D compliant serial ports via DB-25 connectors
  • Each port configurable as DTE (Data Terminal Equipment) or DCE (Data Communications Equipment) using onboard jumpers
  • Supports asynchronous communication for modems, terminals, PLCs, instrumentation, and legacy peripherals
• Parallel Interface:
  • One 50-pin high-density Centronics-style connector for IEEE 1284-compliant parallel printer interface
  • Enables connection to industrial printers, plotters, and other parallel devices
• SCSI Interface:
  • One 50-pin high-density SCSI connector (Centronics-style)
  • Supports SCSI-1 and SCSI-2 peripheral devices including hard drives, tape drives, and optical storage
  • Onboard socketed termination resistors allow flexible configuration (end-of-bus or middle-of-bus)
  • Termination power (TERMPWR) provided and fused at 1 A via the P2 adapter board
• Ethernet Connectivity:
  • One 10/100 Mbps Ethernet port (RJ-45) supporting standard TCP/IP networking
  • Facilitates remote monitoring, system management, and integration into LAN environments
• Internal Modem Support:
  • Serial Port 2 routed to an internal modem connector for dial-up or remote access applications
  • Ideal for out-of-band management, backup communication, and field service connectivity
• P2 Adapter Board Requirement:
  • Requires a dedicated P2 adapter board to route signals between the VME backplane and the MVME712M6E module
  • Ensures proper signal integrity, grounding, and power distribution
  • Breaks out critical I/O lines including SCSI, serial, parallel, and Ethernet
• Status Indicators:
  • Green LED: Indicates presence of termination power (TERMPWR)
  • Yellow LED: Indicates transceiver power status for communication interfaces
• Electromagnetic Protection:
  • Front panel includes EMI/RFI shielding to minimize interference
  • Electrostatic discharge (ESD) protection on all I/O lines
  • Designed for stable operation in electrically noisy industrial and military environments
• Modular and Serviceable Design:
  • Supports field replacement of connectors and components
  • Enables long-term deployment in systems requiring high availability and serviceability

• Test and measurement equipment needing reliable, multi-protocol I/O connectivity
• Communication gateways and protocol converters in distributed control networks
• Medical and scientific instrumentation requiring standardized peripheral connectivity

Manufacturer and Support

The MVME712M6E was developed by Motorola’s Embedded Communications division, which transitioned through Force Computers, GE Intelligent Platforms, Emerson Network Power, and later became part of Abaco Systems. As a legacy product, it is no longer in active production but remains supported in existing systems through specialized industrial automation suppliers and embedded systems distributors. Technical documentation, spare units, and integration guides are available from archived manufacturer resources and component vendors. Due to its rugged design, proven reliability, and compatibility with long-deployed VME systems, the MVME712M6E continues to be used in mission-critical applications where interface flexibility, environmental resilience, and system longevity are essential.
