EMERSONMVME5500 Series VMEbus Single-Board Computer

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 configurable 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-definable 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 fulfill the traditional functions of 

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

setup and debug, and operating system booting. 

Emerson’s innovative firmware (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.
