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.

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.
