Motorola MVME2600 manual MVME761 Transition Module, Serial Interface Modules

3

Functional Description

❏Fused SCSI terminator power developed from the +5V DC present at connector P2

❏A 64-pin DIN connector to interface the EIA-232-D, parallel, SCSI, and Ethernet signals to the MVME712M

MVME761 Transition Module

The MVME761 transition module (Figure 1-12 on page 1-26) and P2 adapter board are used in conjunction with the MVME2603/2604 base board.

The features of the MVME761 include:

❏A parallel printer port (IEEE 1284-I compliant)

❏An Ethernet interface supporting 10BaseT/100BaseTX connections

❏Two EIA-232-D asynchronous serial ports (identified as COM1 and COM2 on the front panel)

❏Two synchronous serial ports (SERIAL 3 and SERIAL 4 on the front panel), configurable for EIA-232-D, EIA-530, V.35, or X.21 protocols

❏Two 60-pin Serial Interface Module (SIM) connectors

Serial Interface Modules

The synchronous serial ports on the MVME761 are configurable via serial interface modules (SIMs), used in conjunction with the appropriate jumper settings on the transition module and base board. The SIMs are small plug- in printed circuit boards which contain all the circuitry needed to convert
