THE
43
TELEPRINTER
SERVICE MANUAL
INTRODUCTION
This
manual
provides servicing
information
for
the
43
Basic
Teleprinter
Terminals.
The
parts
included in
the
service manual provide instructions for
use by
crafts
personnel
when
performing
the
servicing tasks required for
the
installation, testing,
troubleshooting
and
routine
maintenance
of
the
43
KSR
and RO.
The
task flow
chart
on
the
next
page illustrates
the
intended
repair and
servicing activities and associated
manual
parts.
A brief training course and
the
maintenance
spares as
recommended
in the
parts
indexes are available from
Teletype
Corporation. Crafts personnel should
be
properly
trained
and
have access
to
maintenance
spares before
attempting
to
repair
or
service
the
43
Teleprinter.
This manual was reissued
to
provide servicing
information
for
KSR
and
RO
Teleprinters with
either
sprocket
or
friction feed capability and
equipped
with
an integrated Terminal Data
Unit
(TDU), an integrated Terminal Auxiliary
Unit
(TAU,
TAUl,
TAU2),
or
no
integrated terminal
unit
(no
TU). Also
included in this manual is servicing
information
for
the
430900
Answer-Back
Modification Kit.
For
complete
repair
information
on
43
Basic
Teleprinter
terminals
without
a TDU,
including repair
of
all
major
components
except
for
the
TAU, refer

GENERAL
1.01 This section provides a general descrip-
tion
of
the
43 Basic
Teleprinter
terminals
and station arrangements.

shown in this
manual are
Teletype

part
numbers.
2. DESCRIPTION
2.01 The
43
Keyboard Send Receive KSR
sprocket feed
station
with integrated
Terminal Data Unit (TDU) consists
of
a keyboard
printer
station
arrangement
and a
modular
500
or
2500
telephone.
The
station
connects
directly
to
the
switched
telephone
network
by means
of
a
modular
cord.
2.02 The 43 KSR and RO
Stations
are also
available with friction feed roll
paper
handling capabilities
and
an answer back circuit
card.
2.03 Various
43
terminal arrangements are also
available
without
a directly
connected
telephone witb
either
friction
or
sprocket
feed
paper handling as follows (See Fig. 2).
•KSR
with Terminal Auxiliary
Unit
(TAU)
that
has an EIA Interface.
•KSR
with Terminal Auxiliary
Unit
(TAUl)
that
has a single
combined
EIA/Current
inter-
face
port.
•KSR
with
Terminal Auxiliary
Unit
(TAU2)
that
has dual
combined
EIA/Current
interface
ports.
•KSR
with
no
internal
data
unit
that
has a
Transistor-Transistor Logic (TTL) voltage level
interface.
•Receive Only (RO) terminals with
either
an
internal
data
set, TAU,
TAUl,
or
no internal
data
unit.
2.04 Terminals
with
EIA interface are normally
connected
to
private lines
or
to
an external
data
set
which
is
connected
to
the
public switched
telephone
network.
2.05 Terminals with no internal
data
unit
or
current
interface are usually directly
connected
to
a nearby
data
device
or
computer.

friction
feed
terminals,
the
paper
roll is held by a
paper
supply
assembly
that
is
mounted
to
the
rear
of
the
terminal.
2.11
The
terminals
operate
on
a
115
V ac,
:!:10%,
50-60
Hz source
of
power
at
100
watts.
Power
is
controlled
by an
on-off

type
switch
located
at
the
right
rear
of
the
hous-
ing. A
10-foot
power
cord
is
included with
the
terminal.
2.12
The
teleprinters
weigh
approximately
30
pounds
and
those
with
modular
phone
connectors
can readily be moved and
reconnected
in
another
location
by
the
user.
2.13

is
furnished with

and
one
additional

are needed
to
complete
a

TTL
interface
or
a

set
and
EIA

require
a locally engineered

GENERAL
1.01 This section
provides
station
installation
and removal
information
for
the
43
KSR and RO
Station
(Fig.
1.).
1.02
For
additional

Options.
1.03
The
43
Teleprinter
is
furnished fully
assembled
and
tested
with an
integrated
TAU,
TAUl,
TAU2,
TDU
or
no
integrated
termi-
nal
unit
ready
to
connect
to
an
external
communi-
cations
device
or
distant
terminal
or
between
a
modular
500DM
or
2500DM-type
keyless tele-
phone
and
the
line
telephone
jack. Where
telephones
and
jacks
are
not
of
the
modular
type,
they
must
be
converted
to
the
modular
type
before
station
installation.
Note: When installing a
terminal
with an
integrated
TDU
(KSR
or
RO
with
telephone)
obtain
locally
or
from
Teletype
Corporation
at
least
one
modular
cord
of
the
appropriate
length
to
connect
between
the
telephone
and
the
43
Teleprinter
(Fig. 4
).
Discuss with
customer
where
the
teleprinter
and
phone
are
to
be installed
before
obtaining
cord(s).
1.04
Before
starting
the
installation
procedure,
verify
that
paper
in
addition
to
the
Basic
43
Teleprinter
Arrangement
is
present
at
the
installation
location.
