Features:

4 25-pin multi-protocol EIA-232-D serial ports

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

The MVME712M is compatible with the MVME147. MVME1600. MVME162. MVME2600. MVME167. MVME2700. MVME177. MVME3600. MVME4600.

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

The P2 adapter assembly routes I/O signals 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 that have four industry-standard DB-25 connectors on the front panel.

The serial ports can be configured as EIA-232-D DTE or DCE via a patch cable arrangement on the MVME 712M.

The MVME712M also has an Ethernet port, a SCSI port, and a printer port on the front panel.

In addition, the MVME712M routes EIA-232-D Port 2 signals to the internal modem.

The MVME712M requires the use of the P2 adapter board, which is not included.

PPMC750-2xxx Description

The PPMC750-2xxx is an extended form factor version of the PPMC750 Processor PCI Mezzanine Card (PPMC) board (see the Processor PMC Standard for VITA-32-199x Processor PCI Mezzanine Cards for more information).

The PPMC750-2xxx is 1.5 times wider than normal at 111 mm. It is based on the PowerPC MPC750 processor and the Hawk PCI host bridge/system memory controller.

Standard features of the PPMC750 include 1MB of L2 cache, an on-board bank of SDRAM (32MB to 128MB), 8MB of FLASH, and optional SDRAM memory expansion.

In addition to the standard features of the PPMC750. the PPMC750-2xxx features 1MB of socketed FLASH, a 10/100TX Ethernet channel, a 190-pin Mictor debug connector, and a serial port debug connector.

Four 64-pin PMC connectors on the PPMC750-2xxx are used to connect the PPMC750-2xxx to the motherboard.

A 10-pin right-angle connector located on the side of the motherboard provides the interface to the asynchronous serial port. A 16-pin header provides the interface to the processor’s JTAG/COP port.

A 190-pin Mictor connector on the secondary side of the board provides debug access to the processor bus.

The serial port and JTAG/COP interfaces and ABORT_L signals are also routed to the PMC P14 connector for access to the carrier board.

The PPMC750-2xxx includes a 140-pin AMP connector mounted on the auxiliary side of the board to provide sockets for memory expansion functions.

The presence of this connector increases the height measurement of the components on both sides beyond the standard PMC height.

The MVME162FX is based on the MC68040 or MC68LC040 microprocessor.

Different versions of the MVME162FX are available with 4MB, 8MB or 16MB of unprotected DRAM, 8KB SRAM (with battery backup), daily clock (with battery backup),

Ethernet transceiver interface, two serial ports with EIA-232-D or EIA-530 or EIA-485/422 interfaces, six timers, watchdog timer, one PROM socket,

1MB of Flash memory (one Flash device), four IndustryPack (IP) interfaces with DMA, SCSI bus interface with DMA, VMEbus controller, and 512KB of SRAM with battery backup. a “no VMEbus” option is also available.

The I/O on the MVME162FX is connected to the VMEbus P2 connector. The main board is connected via a P2 transition board and a cable connecting the transition board.

The MVME162FX supports the transition boards MVME712-12. MVME712-13. MVME712M, MVME712A, MVME712AM, and MVME712B (referred to in this manual as MVME712x unless otherwise noted).

The MVME712x transition board provides configuration headers and industry standard connectors for I/O devices.

I/O connections to the serial ports on the MVME162FX are also made via two DB-25 front panel I/O connectors.

The MVME712 series transition boards are designed to support the MVME167 boards, but can be used on the MVME162FX if some special precautions are taken.

(For more information, see the Serial Communications Interfaces section of the MVME162FX Embedded Controller Installation and Use Manual).
