TECHNICAL

DESCRIPTIO

N

Physical

The

MPP

is

a 9U

high

PCB

with

integral

front

panel.

Some

aspects

of

MPP

operation

are

determined

by

link

settings.

External connections

Each

module

is

plugged

into

the

main

chassis

backplane

bus

system

via

two

DIN41612

connectors

J1

and

J2

(Figure

1

-

1 ).

Figure

the

main

chassis

backplane

bus

interconnections.

Diagnostic port

A 9

-

pin

D

-

type

connector

is

provided

on

the

front

panel.

The

pinout

is

listed

in

Table

2

-

4.

The

diagnostic

port

signals

are

also

available

at

connector

‘g’

at

the

rear

of

the

chassis

backplane

(Tabl

e 2

-

5).

Chassis backplane

The

signals

passing

through

J2

are

available

at

the

rear

of

the

main

chassis

backplane.

The

rear

backplane

connectors

are

shown

in

Figure

2

-

. For

additional

information,

refer

to

the

Chassis

User

Manual

(Ref

008

-

5097).

Connector

J1

links

the

MPP

to

the

I/O

modules

and

is

represented

on

the

rear

of

the

chassis

backplane

by

Area

‘d’.

Area

‘d’

consists

of

extensions

to

the

pins

of

the

J1

mating

connector

(96

pins

in

three

columns

a,

b and

c).

Pins

07

to

10

of

columns

‘b’

and

‘c’

are

specially

extended

to

enable

the

installation

of

the

chassis

address

setting

links

(see

Figure

2

-

5

).

Column

‘b’

of

connectors

J2

links

each

MPP

to

the

other

MPPs

via

the

Inter

-

Processor

Communications

Bus.

Columns

‘a’

and

‘c’

of

connectors

J2

link

each

MPP

to

the

expansion

bus

via

rear

backplane

connectors

‘e’.
