TRANSITION MODULES

The MVME761 transition module provides industry-

standard connector access to the IEEE 1284 parallel

port, a 10BaseT or 100BaseT port via an RJ-45

connector, two DB-9 connectors providing access to

the asynchronous serial ports congured as EIA-574

DTE and two HD-26 connectors providing access to

the sync/async serial ports. These serial ports, labeled

as Serial 3 and Serial 4 on the faceplate of the MVME761,

are individually user-congurable as EIA-232, DCE or

DTE via the installation of Emerson Serial Interface

Modules (SIMs). A P2 adapter board provides interface

signals to the MVME761 transition module. Two

separate P2 adapter boards are available: one for 3-row

backplanes and one for 5-row backplanes. The 3-row

P2 adapter board provides connection for 8-bit SCSI.

A 5-row P2 adapter board supports 16-bit SCSI and

PMC I/O.

The MVME712M transition module provides

industry-standard connector access to the Centronics

parallel port, a narrow SCSI port, and four DB-25

connectors providing access to the asynchronous/

synchronous serial ports jumper congurable as

EIA-232 DCE or DTE. A P2 adapter board provides

interface signals to the MVME712M transition

module. The 3-row P2 adapter board also provides

connection for 8-bit SCSI. To gain access to the

additional user-denable I/O pins provided via the 5-row

VME64 extension connector, a special P2 adapter

board is available. This adapter panel replaces the

traditional 3-row P2 adapter board and extends its

capability by providing access to the PMC I/O pins.

Software Support

FIRMWARE MONITOR

Firmware must fulll the traditional functions of

power-on self-test (POST), initialization, low-level

setup and debug, and operating system booting.

Emerson’s innovative rmware (known as MOTLoad)

that is resident on the MVME5500 exceeds these

requirements with expanded features such as

interrupt driven I/O, more comprehensive power-up

tests and extensive diagnostics with new scripting

capability. And of course, MOTLoad provides a

debugger interface similar to the time proven “bug”

interface on previous VMEbus boards from Emerson.

OPERATING SYSTEMS AND KERNELS

WindRiver Systems VxWorks, TimeSys Linux, Green

Hills Software INTEGRITY and LynuxWorks LynxOS are

available for the MVME5500.

LIBRARIES

VSI/Pro VSIPL libraries from MPI Software Technology

are available on the MVME5500. BETA 4.0 NDDS from

Real Time Innovations (RTI) running over GbE and Native

VME are available on the MVME5500 through RTI.
