CABLE

AND

FUNCTION

It

the

CTO

will

be

“Messaging

Enabled”.

If

the

CTO

will

be

used

as

a

message

display

terminal

(MDT)

you

must

use

the

correct

cable.

The

messaging

cable

will

be

tagged

indicating

it

is

“message

ready”.

If

messaging

will

not

be

used,

please

use

the

cable

without

a

tag.

WIRING

FOR

A

CTO

Because

the

CTO

has

its

own

power

connector

in

order

to

facilitate

its

wiring,

the

following

steps

are

to

be

followed;

1)

Install

the

TM2/TM2J

as

normal,

ensuring

that

all

the

rules

are

followed

and

make

sure

that

the

TM2/TM2J

comes

on

and

it

registers

with

the

network.

2)

Disconnect

the

6

pin

power

plug

from

the

TM2/TM2J

and

connect

it

into

the

3

pin

female

plug

coming

from

the

CTO

pig

tail

loom.

Make

sure

that

the

lock

of

the

6

pin

power

Molex

locks

onto

the

tab

of

the

3

socket.

3)

Connect

the

6

pin

side

of

the

pigtail

from

the

CTO

into

the

TM2/TM2J.
