Description.

The MVME712M is an I/O transition module for Motorola MPU VME Modules, VME Processor Modules, Embedded Controllers, and Single Board Computer (SBC) series processor modules.

The MVME712M is used as an interface between the processor module and its peripherals. The purpose of this module is to provide rear-panel The purpose of this module is to provide rear-panel industry-standard connectors to simplify the customer’s external cable requirements.

P2 adapter boards and cables are provided for interconnecting the MVME712M to peripheral devices. interconnecting the MVME712M to the MVMExxxx. the P2 adapter assembly transfers I/O signals and ground from the P2 connector on the chassis backplane to the MVME712M, and from the P2 adapter assembly to the MVME712M. at the VME Module MPU connection. At the VME module MPU connection, the P2 adapter assembly transfers I/O signals and ground from the P2 connector on the chassis backplane to the MVME712M.

The MVME712M routes the signals to four serial ports, which are realized through four industry standard DB-25 connectors on the MVME712M. Serial Ports. The serial ports can be configured as EIA-232-D DTE or DCE via jumpers on the MVME712M. The serial ports can be configured as EIA-232-D DTE or DCE via jumpers on the MVME712M.

The MVME712M also has an Ethernet port, a SCSI port, and a printer port on the front panel. Printer Port. In addition, the MVME712M routes EIA-232-D Port 2 signals to the internal modem. signal to the internal modem.
