The MVME712A/AM is an I/O conversion module for MOTOROLA MPU VME modules, VME processor modules, embedded controllers, and Single-board Computer (SBC) family of processor modules. The MVME712M is compatible with MVME147, MVME1600, MVME162, MVME2600, MVME167, MVME2700, MVME177, MVME3600 and MVME4600. The MVME712M serves as the interface between the processor module and its peripherals. The module is designed to provide rear panel industry standard connectors to simplify external customer cable requirements.

The P2 adapter assembly routes the I/O signal and ground from the P2 connector on the chassis backplane (at the VMEmodule MPU connection) to the MVME712M. The MVME712M routes signals to four serial ports through four industry-standard DB-25 connectors on its front panel. The serial port can be configured as EIA-232-D DTE or DCE via the jumper arrangement on the MVME 712M. The MVME712M front panel also has an Ethernet port, a SCSI port, and a printer port. In addition, the MVME712M routes the EIA-232-D port 2 signal to the internal modem.

The MVME712A/AM requires a P2 adapter, but is not included. The functions of P2 adapter board include:
Allows SCSI cables to be connected to other SCSI devices and/or via flat ribbon cables
Connector for the MVME712M • Terminal resistors mounted in receptacles for cable end or cable middle configuration
• Generate terminal power on the P2 adapter from the +5 VDC on the connector P2, and the P2 adapter
Fuse (1 A) on the connector that connects the EIA-232-D port, printer port, SCSI and Ethernet signals to the MVME712M
