MVME2700-1321 to 1361 MVME4604-5342 to 5372

All port I/O controllers reside on the MVME260x, MVME270x,
MVME360x, and MVME460x Single Board Computer modules. The
MVME761 transition module Ethernet and parallel port circuitry is
passive. The serial port circuitry provides multiplexing and buffering
functions (refer to P2 Signal Multiplexing (P2MX) on page 3-4). The
multiplexing function is transparent to the user.

Both MVME761-0x1 models use the same transition module. The
MVME761-001 comes with a P2 adapter that connects to a 3-row DIN
chassis backplane. The MVME761-011 comes with a P2 adapter that
connects to a 5-row DIN chassis backplane.

General Information

Serial Port Interface Modules

You may configure th e asynchronous/synchron ous serial ports (p orts 3 and

4) to the appropriate interface by installing a Serial Interface Module

(SIM). A SIM is a small “plug-in” printed circuit board that converts the
TTL-level synchronous or asynchronous port signa ls to i ndustry standard
voltage levels used by the ports. The SIM contains the receiver and
transmitte r circuits for converting the input and output si gnals of the host
VMEmodule to the appropriate serial data communication protocol.

The SIMs for the MVME761-0x1 are list ed in t he following table.

Installing the Transition Module and P2 Adapter

Installing the T ransition Module and P2 Adapter

Install the MVME761 transition module and P2 adapter in the system
chassis. The P2 adapter is required because the P2 connector on the
transition module is not compatible with the P2 connector on the chassis
backplane.

Use ESD

Wrist Strap

!

Caution

Motorola strongly recommends that you use an anti static wris t strap and a
conductive foam pad when installing boards in a system chassis.
Electronic component s, such as disk d rives, computer boards , and memory
modules, can be extremely sensitive to ESD. Place the board flat on a
grounded, static-free surface, component-side up. Do not slide the board
over any surface.

If an ESD station is not available, you can avoid damage resulting from
ESD by attaching the ESD wrist strap to an unpainted metal part of the
system chassis.

Install the MVME7 61-0x1 in the system chassi s per the Pr ocedur e on page

2-6. Refer to Figure 2-4, whic h shows the cabli ng and connect io ns within

the chassis.

An MVME2600/MVME2700/MVME3600/MVME4600
module that is designed for use with an MVME712M
Transition Module will be damaged if you use it with an
MVME761-0x1 Transition Module.

3Functional Description

Introduction

This chapter provides information on MVME761 transition module and
SIM circuitry, P2 signal multiplexing, and the configuration of the serial
ports.

Circuitry

The MVME761 transition module and the Serial Interface Modules
(SIMs) convert the TTL level signals to and from the MVME260x,
MVME270x, MVME360x, and MVME460x modules to the rece ption and
transmission levels specified by the appropriate port interface standard.

The MVME761 transition module contains a small amount of “house
keeping” circuitry. Bulk capacitors are on the power sources (+5Vdc,
+12Vdc, and -12Vdc). Pullup resistors put the inputs to the MVME260x,
MVME270x, MVME360x, and MVME460x in a known high even when
no SIM is install ed.

The block diagram for the MVME761 transition module is shown in

Figure 3-1. The block diagram fo r the 3 -row DIN ba ckp lane P2 a dapte r is

shown in Figure 3-2. The block diagram for the 5-row DIN backplane P2
adapter is shown in Figure 3-3.

P2 Signal Multiplexing (P2MX)

Because of a limited number of pins on the P2 connector, both the VME

3

processor board and the MVME761 transition module multiplex and de­multiplex some of the P2 signals . Th is function, cal led P2MX is
transparent to the soft ware and the u ser.

Four pins are used for the signal multiplexing:

❏ MXCLK
❏ MXSYNC#
❏ MXDO
❏ MXDI

Sixteen time slots are defined and allocated. The signal multiplexing
sequences are listed in Table 3-1.

MXCLK is the 1 0MHz bit cloc k for the time-multiplexed data lines,
MXDO and MXDI.

MXSYNC# is asserted for one bit time at Time Slot 15 by the
MVME260x, MVME270x, MVME360x, or MVME460x. MXSYNC# is
used by the MVME761 transition module to synchronize with the VME
modules.

MXDO is the time-multiplexed output line from the main board and
MXDI is the time-multiple xed line from the MVME761 transit ion module.
A 16-to-1 multiplexing scheme is used with a 10MHz bit rate.

3

MXSYNC# is clocked out usi ng the falling edge of MXCLK and MDXO
is clocked out with the rising edge of the MXCLK. MXDI is sampled at
the rising edge of MXCLK (the transition module synchronizes MXDI

with MXCLK’s rising edge).
The timing relationships among MXCLK, MXSYNC#, MXDO, and

MXDI are illu strated in Figure 3-4.

Serial Interface Module Circuitry

Serial Interface Module Circuitry

Each Serial Interface Module has a 60-pin connector that provides all
signal and power connections to the MVME761 transition module.

TTL-level signals

All TTL-level signals, with the exception of data and clocks, are active
low. The pullup resistors on the MVME761 transition module drive all
TTL inputs to the SIM to a known logic level.

SIMs

The SIMs have surge s uppressio n circui try for all po rt signals goin g to the
external connector. Thi s consist s of a series r esistor and a dual 15V clamp
diode to chassis ground. All series resistors are 100 ohms except on the
EIA-530 balanced drives, which use 10 ohm series resistors.

❏ EIA-232-D SIMs employ MC145406 ICs as line transmitters to

convert the TTL out put signals from the MVME260x, MVME270x,
MVME360x, or MVME460x module to EIA-232-D voltage lev els.
As line receivers, th e MC145406 ICs convert the EIA-23 2-D i nput
signals to TTL voltage levels which are sent to the VME module.

3

The MC145406 transceiver IC requires a series diode on the +12V
supply and a clamp diode to logic ground on the -12V supply. The
diodes are located on the transition module rather than on the SIM
due to space limitations.

❏ EIA-530 and X.21 SIMs employ AM26C31CD ICs as transmitters

to convert the TTL output signals from the MVME260x,
MVME270x, MVME360x, or MVME460x module to balanced
signals. As line receivers, the AM26C32CD ICs convert the
balanced input signals to TTL signals which are sent to the VME
module.

❏ V.35 SIMs employ LTC1345T ICs as transmitters to convert the

TTL output signals from the MVME260x, MVME270x,
MVME360x, or MVME460x module to balanced signals. As line
receivers, the LTC1345R ICs convert the balanced input signals to
TTL signals which are sent to the VME module.

http://www.mcg.mot.com/literature 3-7

Functional Descr iption

For all port in terfaces, the SIMs support th e transmitter signal element
timing as either input or output signals.

Introduction

This chapter provides the pin assignments for the P2 connector and front
panel port connectors on the MVME761 transition module, as well as for
the SCSI and PMC I/O connectors on the P2 adapters.

MVME761 Transition Module Connectors

P2 connector

Signaling and power from the MVME260x, MVME270x, MVME360x,
and MVME460x are received through connector P2, a 64-pin DIN
connector. Because the P2 adapter reroute s some of th e signals , connector
P2 on the MVME761 transition module is not pi n-for-pin compat ible with
connector P2 on the MVME260x, MVME270x, MVME360x, and
MVME460x modules.

The pin assignments and signal mnemonics for the MVME761 transition
module P2 connector are listed in the following table.
