Motorola 3496B01A P2 Adapter.
The MVME712M is an I/O transition module for Motorola’s MPU
VMEmodule, VME Processor Module, Embedded Controller, and Single
Board Computer (SBC) families of processor modules, referred to in this
manual as MVMExxxx.
The MVME712M is used as an interface between the processor module
and its peripheral devices. The purpose of this module is to provide rear
panel industry-standard connectors that simplify external customer cable
requirements.
The P2 adapter board and cables are supplied for interconnection between
the MVME712M and the MVMExxxx. The P2 adapter assembly routes the
I/O signals and grounds from the P2 connector on the chassis backplane,
at the VMEmodule MPU connection, to the MVME712M.
The MVME712M routes the signals to four serial ports, implemented with
four industry standard DB-25 connectors on its front panel. The serial ports
may be configured for EIA-232-D DTE or DCE through jumper
arrangements on the MVME712M.
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
signals to an internal modem.
