The MVME712M is used as the interface between Motorola's MVME1xx RISC and CISC Single Board Computers, such as the MVME147S, MVME162, MVME167, and MVME187 families of VMEmodules, and their peripheral devices. A P2 adapter module and cables are supplied for interconnection between the MVME712M and the MVME1xx-family VMEmodule.
The MVME712M has four DB-25 connectors for the serial ports, one 36-pin connector for the printer port, one 50-pin connector for the SCSI port, and one DB-15 connector for the Ethernet port. The serial ports may be configured for use as DTE or DCE through jumper arrangements on the MVME712M.
