HOW TO OPERATE INSTRUCTIONS
(Pages 1 Through 13)
INTRODUCTION
The 43 Basic KSR Teleprinter provides character-at-
a-time keyboard-printer send-receive operation. Trans-
mission speeds are 10 characters per second (cps)
(100 wpm) or 30 cps (300 wpm) and can be selected
by the attendant to match the remote station.
The 43 Teleprinter may be connected to an external
communications device (modem) which may be
associated with a telephone for connections and for
transmission of data. A permanent connection via
private line may also be used in these arrangements.
When connected directly to an associated modular
telephone, calls are originated in a manner similar to
regular telephone calls and can be answered either
automatically or manually. The telephone can be
used for normal voice communication or data mes-
sages can be exchanged over the telephone line
using controls on the 43 Teleprinter.
In some arrangements the 43 Teleprinter may be
connected directly to a computer or remote terminal.
On sprocket feed printers, messages with up to 132
characters per line are printed on 12 inch wide
sprocket feed paper. The paper may be fed from a
supply box or limited amounts can be placed in a
paper holder that can be attached to the rear of the
teleprinter. (See Page 8 for paper suppliers.)
On friction feed printers, messages up to 80 characters
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 tractor feed printer accepts paper widths from
3-1/2 inches up to 12 inches. Messages up to 80
characters per line may be printed on 12 inch sprocket
feed paper.
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 8).
A pullout directory card holder under the front of the
keyboard may be used to write in frequently used.
telephone numbers and note any extensions (see
Page 24). Exceptions to standard operating features
should be recorded on the reverse side of the card.

or receive data messages. However, when not in use,
the power to the teleprinter may be turned off
without affecting the normal use of the telephone.
In some applications, turning off power may
affect operation of other terminals in the system.

ESTABLISHING COMMUNICATIONS WITH DISTANT TERMINALS
Procedures for Arrangements Without an Associated Telephone Directly Connected to the Terminal
® Establishing connection and transferring to the Data mode on these arrangements
is basically under the control of the directly connected communications device
(modem) and its associated telephone over the switched-network or, without a
telephone over private lines. In some arrangements terminals are directly connected
to the distant terminal or computer. Use of these external devices should be speci-
fied locally since many variations are possible, ie, pushbuttons on modem or on
phone, exclusion keys, automatic answer, etc.
@ The procedures as shown below, that normally apply to operation of the controls of
the terminal, should be followed:
® Before transferring a telephone call to the Data mode (call originated or answered)
or to place terminal in a ready condition:
1. Turn on ac power (see Page 2).
9 Clear any alarm condition (paper-out, cover open).
3. Depress TERM READY key (if not lit). Key should light.
E Transfer to Data mode
e The DATA key lights under control of the external device or distant station:
1. Data can be sent or received on-line only when the DATA key is lit and
the LOCAL key is not lit.
2. On some arrangements the DATA key may light immediately without
the TERM READY key being lit.
8 To disconnect a telephone call in DATA mode
e Calls may be disconnected as follows:
1. An EOT code is received. (TERM READY key may light.)
2. The LOCAL key is depressed. (LOCAL key will light.)
3. Paper-out and eight received line feeds (LOCAL key will light.)
4. Other log-off procedures, loss of data signals, etc.
Procedures for Arrangements With an Associated Telephone Directly Connected to the Terminal
@® Telephone calls must be originated and answered as follows in order to send and receive messages or talk. Calls
can also be disconnected as described below. Power must be on to complete a data call (see Page 2).

TELEPRINTER SUPPLIES AND MAINTENANCE
Ribbon
The ribbon cartridges provided by Teletype Corpora-
tion utilize ribbon material chosen for its physical
stability and nonabrasive inks which have a lubrica-
ting quality. The use of ribbon cartridges without
these required properties may reduce print head
performance and life in addition to shorter ribbon life.
The ribbon cartridge should be replaced whenever the
ribbon becomes frayed or print density becomes light.
Ribbons obtained from Teletype Corporation should
produce 5 million legible printed characters.
The Teletype Corporation part number for a package
of six ribbon cartridges is TP430484 and can be
ordered from Teletype Corporation, using the order
form furnished with each terminal.
Sprocket Feed Paper
Paper for the 43 Sprocket Feed Teleprinter must be
12 inch sprocket feed, while tractor feed paper may
be from 3 inch to 12 inch sprocket feed. Both tele-
printers require paper with folds or horizontal per-
forations located midway between sprocket holes and
standard sprocket hole size and spacing. This paper
may be single-ply with 8-1/2 inch folds to provide 11
inch x 8-1/2 inch copy when the 1/2 inch wide

sprocket hole strip is removed at the edge serrations.
(Characters are printed to within 7/8 inch of the left
and right paper edge before the strips are removed.)
Similar replacement paper may be obtained from the
supplier listed on the original paper box or from other
suppliers listed below or in the telephone book yellow
pages.
Other types of sprocket feed paper with different
form lengths, lighter weight, no edge serrations or
additional copies, etc, may also be used. Multicopy
forms consisting of the original and 2 copies of 12
pound basic paper (using 8 pound basic carbon paper)
produce clear copy. Acceptable copy may also be
obtained on variations of multicopy forms using
different weight paper or carbonless paper, however
all paper or forms should be tried before ordering
large quantities. Crimped multiple part forms are
not recommended and stapled forms are not allowed.
Consult your paper supplier for specific needs to
assure complete satisfaction. |

interrupted by the remote station.
Note:
The use of this key is system dependent. It
may not be operable with some remote stations.
When operable, its use should be under direction of
the system.
e The INTRPT key operates as follows:
E It lights under control of the remote station.
When lit, keyboard sending is disabled.
® If depressed momentarily when lit, the interrupt
is canceled.
@ If depressed when not lit, the remote station
sending may be interrupted ie, stop sending.
Locally bell rings and key lights momontarily.
O Interrupt is also canceled by a disconnect or when
power is turned off.
Key lights or flashes when alarm condition
exists.
e Lights when:
E Paper-out condition is sensed (sprocket and
tractor feed). This is an advance warning that
eight received line feeds later (in the Data mode),
20
the call will disconnect. Also, after thirteen line
feeds, paper will be out at the print head.
MS Low paper condition is sensed (friction feed).
This is an advance warning that 25 to 50 feet
of paper remain on the paper roll.
8 When the cover is opened.
@ When printer test is operated.
@ Flashes when:
@ Teleprinter is in a Loopback Test mode.
@ Can be cleared by:
® Replacing paper or closing cover.
№ Оп friction feed printers, if a partially full paper
roll is installed, it may be necessary to depress
the RESET key on the paper roll support. See
Page 12.
@ When flashing by:
ESC = sequence.
Depressing LOCAL TALK key.
Turning off power.
Note: In some systems, the ALARM key may be
flashing during normal operation accompanied by
printing. Unless otherwise instructed, the Alarm
should be cleared after extended periods of flashing.
See Page 22.
PRINTER TEST, PARITY, DUPLEX AND CHARACTER SPEED KEYS
An independent test of the printer is pro-
vided for use by attendant or field service
personnel. Test consists of continuous
printing of the 94 character printed set as
shown below. During test, bell rings and automatic
return of carriage and line feed is performed within
margin restraints.ÿ Test should not be performed in
Data mode since Data mode will be terminated and a
telephone call will be disconnected. Depression of
PRINTER TEST key initiates test. Test is terminated
when this key is released. (See Pages 14 through 18
and 20 for keys that light or extinguish during test.)
Sample of Test Message
Half-Duplex (key up) — printer copies data
sent and received. The printer can be blinded
to on-line transmission from the local
keyboard while receiving messages simul-
taneously from the remote sender. This mode is
known as Full Duplex (key down — DN).
Note: The local CR-LF function will not be per-
formed in Full Duplex.
Line Length 72 — Option 432b.%
Line Length 80 —
Option 432c. +
PASTA ()8+,-,/0123456789:;<=>TRABCDEFGHIJKLMNOPORSTUVUXYZE\ 37 _‘abcdefghi jkinnoparstuvexyz{1}"
1 "$247 ()ж+, - ‚70123436789: ; <= =>[email protected] _abcdefghi jkxlnnopqrstuvwxyz(:)”
0
The proper position of this key depends on
system application. The remote sender may
or may not be equipped to send correct
(even) parity. The 43 Teleprinter sends even
parity as factory furnished, Option 434a. When
PARITY key is on, characters received with incorrect,
(odd) parity will print as substitute character sym-
bol ®, when parity is off, the character that is
received will be printed or performed if it is a printable
character or a valid function. The PARITY key
alternately locks down (DN) for parity off or releases
up for parity ON to set parity checking mode.
- Option 431b. f As Factor
§ = Option 431c. Furnished -
In Half-Duplex, the printer copies all data sent and
received but only one sender can operate at a time
without interference, ie, characters from the keyboard
will be inhibited if the unit is receiving on-line. The
key locks down or releases up.
In order to communicate in the Date mode,
the transmission rates of the sending and
receiving stations must be the same. This
key alternately locks down or releases up
and sets the on-line operating speed of the station to
either 30 (key up) or 10 (key down — DN) characters
per second (300 or 100 words per minute).
+ If margins are set for less than 96 characters, a character will be skipped (not printed) each time a new line
starts except for the new line that starts a new cycle of printing.
+ See backside of directory card for record of any option exceptions that may have been enabled. Right margin
must be set on tractor feed sets using narrow paper.

SPECIAL KEYBOARD CHARACTERS
@ Codes for the following characters are generated
from the 43 Teleprinter keyboard by use of the
CTRL key and the key with the symbol shown,
operated together.
These characters are not functional in the Model 43
Teleprinter but may be used in some systems.
DC1
ETB
ENQ
DC2
DC4

SYN
STX
O The special escape sequences listed below (in
addition to those on Page 4) are functional in the
43 Teleprinter by sending (or receiving) the charac-
ter immediately following the escape character
(ESC key).
Use of other escape sequences are system dependent.
(Some characters following ESC may print on tractor
feed sets.)
Completely func-
tional only on
arrangements
with a directly
connected mod-
ular telephone.
Alarm lamp
| may still flash.
ESC > Analog Loop-Back
ESC < Digital Loop-Back §
ESC = Clears either Loop-Back
ESC w Returns carriage and
paper advances one line.
s Used under control of remote station.
O Repeat speed varies depending on 10, 30 cps on
line and approximately 50 cps locally.
KEY TELEPHONES AND EXTENSIONS
® The modular telephone directly connected to the 43 Teleprinter is used in accordance
with the originating answering and disconnecting procedures on Pages 6 and 19. In
these arrangements other phones cannot be used to originate data calls. The phone
may be or have an extension and therefore would be subject to the limitations of
extension telephones, for example:
E Lifting handset, dialingor talking on an extension can interfere with data transmission.
E Calls may not be disconnected if the extension is off-hook.
® In some cases, the modular phone may be a “designated” extension of a key telephone
set. These extensions may be arranged (by use of an exclusion feature) to prevent inter-
ference from other phones. The installer should indicate the presence of any extension
phones on the directory card.
@ Key telephones may be associated with external data sets connected to the terminal.
Use of these phones to originate and answer talk and data calls are under the control of
the data set and should be specified locally.
23
WHEN TROUBLE OCCURS
Trouble that is encountered with the terminal should
be reported as locally specified. A number to be
called in case of trouble may be entered on the direc-
tory card pullout by the installer.
If it can be determined that the trouble is in the
remote equipment, the attendant at the location in
trouble should follow local procedures for that area.
The following table of analysis questions is arranged
to aid in the isolation of a trouble for:
@ Local correction.
e Correction at the remote location.
e Advising service personnel of Analysis Question
results in advance of trouble visit.
