INTRODUCTION

The

43

Basic RO

Teleprinter

provides character-at-a-

time

receive-only

printer

operation.

Data

reception

is

normally

provided

at

30

characters

per

second

(cps)

(300

wpm).

*

The

43

RO

Teleprinter

may

be

connected

to

an

external

communications

device

or

contain

an

inter-

nal

data

set

and

may

be associated

with

a

telephone.

A

permanent

connection

via private line

may

also be

used in

the

arrangements

with

an

external

device.

Calls

may

be answered

and

disconnected

automati-

cally over

the

telephone

line.

In

some

arrangements

the

43

RO

Teleprinter

may

be

connected

directly

to

a

computer

or

remote

terminal

which will

control

Data

mode

transfer.

*See reverse

side

of

directory

card

for

a

record

of

an

option

exception

that

provides

data

reception

at

10

characters

per

second

(cps)

(100

wpm)

or

any

other

exceptions

to

standard

operating

features.

Messages are

printed

with

up

to

132

characters

per

line

on

printers

equipped

for

12

inch

wide

sprocket

feed

paper.

Sprocket

feed

paper

may

be

fed

from

a

supply

box

or

limited

amounts

can

be

placed

in a

paper

holder

that

clips

on

the

rear

of

the

teleprinter.

On

friction feed

printers,

messages

up

to

80

charac-

ters

per

line are

printed

on

8-1/2

inch

wide roll-type

paper.

The

roll is

held

in

a

support

attached

to

the

rear

of

the

teleprinter.

The

ribbon

is

part

of

a

cartridge

that

can

be

readily

replaced

with

the

cover

open.

Replacement

ribbon

cartridges

can

be

obtained

from

Teletype

Corporation

(see Page

6).

An

order

form

is

included

with

each

new

ribbon.

A

pullout

directory

card

holder

under

the

front

of

the

teleprinter

may

be used

to

write

in

frequently

used

telephone

numbers

and

note

any

extensions

(see Page 9).

Note:

The

paper

used

with

the

sprocket

feed

teleprinter

is a

new

12

inch

wide

sprocket

feed. See

Page 6

for

ordering

information.

COMMUNICATIONS WITH

DISTANT

TERMINALS

• Establishing

the

Data

mode

automatically

is

basically

under

the

control

of

the

communications

device

(modem)

over

the

switched-network

or

over private lines.

In

some arrangements terminals are directly con-

nected

to

the

distant

terminal

or

computer.

Use

of

external

devices should be specified locally

since

many

variations are possible, ie,

pushbuttons

on
