EXTENSION CHASSIS ADDRESSING

The

chassis

address

is

set

up

on

links

on

the

chassis

backplane.

The

physical

locations

of

the

links

are

indicated

by

small

triangles

in

columns

‘b’

and

‘c’

of

areas

‘d’

in

Figure

2

-

3.

On

the

chassis

backplane

the

links

are

identified

as

UNIT

ID0

to

UNIT

ID3.

The

presence

of

a link

sets

the

corresponding

address

bit

to

‘0’.

If

a link

is

absent

the

corresponding

address

bit

is

a ‘1’.

The

full

range

of

chassis

address

link

settings

is

given

in

Figure

POWER SUPPLIES

A pair

of

auctioneering

diodes

combines

the

two

5.4Vdc

power

supplies

from

the

chassis

-

mounted

PSUs

into

a single

5Vdc

(nominal)

supply

for

the

whole

module.

The

12V

outputs

from

the

chassi

s

-

mounted

PSUs

are

not

used

by

the

MBB.

A ‘power

on

clear’

pulse

resets

the

control

logic

when

the

power

supply

first

comes

on

line.
