Series
AH
Teleprinter
1-1.
GENERAL
The
Series
AH
Teleprinter
is
a
solid-state,
electronic,
receive-only
unit
which
provides
a
5
x
7
dot
matrix
printout
upon
receipt
of
serial
data
from
appropriate
transmission
sources.
The
unit
is
de-
signed
for
continuous-
or
intermittent-duty
applications,
and
is
capable
of
printing
asynchronously
at
any
speed
up
to
30
characters
per
second.
Series
AH
Teleprinters
are
designed
to
operate
from
either
a
115
V
AC
or
230
V
AC,
50
to
400
Hz,
power
source.
Though
the
electronic
control
circuitry
is
advanced,
the
printing
mechanism
of
every
teleprinter
in
the
series
is
simple—and
every
machine
operates
with
little
noise
and
great
reliability.
Thanks
to
the
machine’s
modular
construction,
the
electronic
and
mechanical
assemblies
can
be
removed
easily,
and
many
components
may
be
used
interchangeably,
wherever
feasible.
The
teleprinter
cover
has
a
hinged
lid,
allowing
easy
access
to
the
typing
unit
for
paper
and
ribbon
threading.
A
window,
built
into
the
hinged
lid,
makes
the
copy
visible
during
data
reception
and
provides
a
cutting
edge
for
the
removal
of
completed
messages
from
the
machine.

PRINCIPLES
OF
OPERATION
The
following
is
a
general
discussion
of
the
basic
principles
of
operation.
A
more
detailed
analysis
of
operation
is
provided
in
subsequent
sections
of
the
manual.
a.
Character
Printing
and
Spacing
Printing
takes
place
when
the
paper
is
struck
by
any
of
seven
electronically-activated
needles
mounted
vertically
in
the
carriage
assembly.
The
carriage
assembly
is
moved
along
the
platen
by
a
special
stepper
motor,
which
de-
rives
its
impulses
from
the
electronic
circuitry
of
the
machine.
The
carriage
assembly
moves
eight
steps
for
each
character—the
first
three
steps
provide
the
spacing
between
characters,
and
the
remaining
five
steps
are
used
to
print
a 5
x
7
dot
matrix
character
pattern,
as
illus-
trated
in
Figure
1-2.
The
spacing
mechanism—comprised
of
the
spacing
drive
stepper
motor,
pulley,
drive
belt,
drive
pawl,
and
associated
gears
and
cap-
stans—laterally
positions
the
carriage
assembly
so
that
the
characters
are
displayed
evenly
in
horizontal
lines
on
the
paper.
The
spacer
is
activated
each
time
a
character
or
space
is
called
for
in
the
received
code.
Internal
logic
suppresses
carriage
spacing
when
certain
‘func-
tion’
characters
are
received
by
the
teleprinter.
b.
Paper
Feed
Drive
Mechanism
The
Paper
Feed
Drive
Mechanism—com-
prised
of
pulleys,
drive
belt,
platen,
and
a
paper
feed
drive
stepper
motor—positions
the
paper
vertically
so
that
spacing
between
printed
lines
is
consistent.
4.4
lines
per
inch
are
normally
printed
when
the
unit
is
func-
tioning
in
the
single-line
feed
mode.
Upon
receipt
of
a
‘line
feed’
encoded
character,
the
paper
feed
drive
mechanism
advances
the
paper
vertically
to
the
next
line
position.
Multiple
line
feeds
are
controlled
by
a
three-
position
toggle
switch
at
the
lower
left-hand
side
of
the
front
of
the
unit.
See
Section
3
for
instructions.

c.
Carriage
Return
The
carriage
return
action
is
performed
by
the
spacing
drive
stepper
motor,
drive
belts,
and
gears.
Upon
receipt
of
a
‘carriage
return’
encoded
character,
the
teleprinter’s
control
circuitry
causes
the
spacing
drive
stepper
motor
to
reverse.
When
this
happens,
the
idler
gear
disengages
from
the
right-hand
capstan,
per-
mitting
the
force
of
the
carriage
return
spring
to
return
the
carriage
to
the
left-hand
margin
to
begin
a
new
line
of
print.
A
decelerator,
which
is
an
inertia
device,
cushions
the
car-
riage
assembly
as
it
reaches
the
left
side
of
the
platen.
In
most
instances,
the
carriage
return
function
is
performed
coincidentally
with
the
line
feed
function,
so
that
the
paper
will
be
advanced
vertically
when
the
carriage
is
returned
to
begin
a
new
line.
In
a
Series
AH
Teleprinter,
an
internal
elec-
tronic
counter
records
the
lateral
position
of
the
carriage
at
all
times.
Thus,
if
the
machine
has
been
arranged
for
either
a
50,
69, 74,
or
80
character-per-line
format,
the
carriage
will
automatically
be
returned
to
the
left-hand
margin
when
the
internal
counter
reaches
this
pre-set
number.
This
will
occur
whether
a
‘carriage
return’
character
has
been
received
or
not.
Furthermore,
the
electronic
control
circuitry
of
a
Series
AH
Teleprinter
determines
the
exact
time
span
required
to
let
the
carriage
assembly
settle
at
the
left-hand
margin
before
the
printing
of
a
new
line
is
begun.

SPECIAL
FEATURES
3.
Special
Character
Fonts
1.
Lower
Case
Characters.
The
AH
Tele-
printer
incorporates
a
number
of
features
which
expand
its
printing
capabilities
beyond
those
associated
with
more
traditional
tele-
printer
designs.
The
most
obvious
feature
is
the
unit’s
ability
to
print
lower
case
char-
acters.
The
standard
lower
case
characters
are
formed
on
a 5
x
5
dot
matrix,
rather
than
the
usual
5
x
7
matrix.
As
a
special
option
(specified
by
the
purchaser
at
the
time
of
ordering),
lower
case
characters
can
be
printed
with
descenders
which
actually
extend
below
the
line
of
copy
(as
in
the
letters
‘j’,
‘p’,
‘q’,
etc.).
To
accomplish
this,
the
logic
board—through
its
special
program—moves
the
paper
up
and
down
or;
the
platen
while
printing
is
in
pro-
gress.
This
option
is
available
only
on
machines
operating
at
up
to
15
characters
per
second.
2.
Bold
Face
Characters.
The
Bold
Face
command
to
the
teleprinter
causes
all
sub-
sequent
characters
to
be
printed
in
a
6
x
7
dot
matrix,
instead
of
the
normal
5
x
7.
The
extra
column
of
dots
gives
the
characters
a
heavier
or
‘bolder’
appearance.
This
feature
outmodes
the
more
traditional
change
from
black
to
red
ribbon
for
accenting
portions
of
a
text—and
the
bold
face
characters
appear
on
every
page
of
a
multiple-copy
form.
3.
Expanded
Characters.
The
ASCII
AH
Series
Teleprinter
is
also
equipped
with
an
Expanded
Character
Set,
for
even
more
em-
phasis
than
that
of
bold
face.
Expanded
char-
acters
may
be
used
to
set
off
page
or
paragraph
titles,
or
to
emphasize
material
within
the
text
itself.
An
expanded
character
is
made
up
of
six
unprinted
and
ten
printed
columns,
producing
a
10
x
7
dot
matrix
character.
Note:
though
expanded
characters
appear
to
be
taller
than
normal
ones,
they
are
actually
the
same
height
as
the
others.
Thus,
normal
line
feed
need
not
be
modified
for
these
characters.
b.
Variable-Width
Underlining
The
ASCII
AH
Series
Teleprinter
features
an
‘underline’
character,
printed
far
enough
below
the
text
line
to
enhance
greatly
the
readability
of
the
underlined
characters.
Usually,
the
‘underline’
character
is
eight
columns
wide—-so
that
repeated
underlining
results
in
a
continuous
line
with
an
even
ap-
pearance.
Since
a
normal
character
consists
of
three
blank
columns
and
five
printed
col-
umns,
it
is
necessary
to
suppress
underlining
to
five
columns
below
the
first
character
of
a
sequence.
The
ASCII
AH
Teleprinter
does
this
automatically.
The
unit
also
accurately
underlines
bold
face
and
expanded
characters.

Auto
Message
The
ASCII
AH
Series
Teleprinter
includes
an
Auto
Message
Option
which,
when
activated,
causes
all
of
the
printable
characters
in
ASCII
to
be
printed
after
power
enters
the
unit.
This
option
helps
verify
that
the
printer
is
in
good
working
condition.
However,
the
Auto
Message
Option
does
not
test
the
input
board.
e.
Half-Line
Feed
Feature
This
feature
is
often
used
for
subscripts
or
other
special
requirements.
The
procedure
can
also
work
in
reverse,
for
the
printing
of
superscripts—when
footnoting
is
desired—and
exponents.
f.
Last
Character
Visibility
(LCV)
If
a
pause
in
the
incoming
data
causes
the
carriage
to
stop
printing
for
more
than
one
second,
a
special
interval
line
feed
advances
the
paper
21/2
lines
upward.
This
makes
the
last
characters
much
more
readable.
When
incoming
traffic
resumes,
the
platen
retracts
2%
line
feeds
and
continues
printing
from
the
point
where
it
had
stopped.

96-Character
Mode
In
addition
to
the
usual
64-
and
128-char-
acter
modes
of
the
ASCII
code,
the
ASCII
AH
Teleprinter
offers
a
96-character
mode
with
both
upper-
and
lower-case
characters.
h.
Full
Monitor
Mode
In
its
Full
Monitor
Mode,
the
ASCII
AH
Teleprinter
prints
3
unique
symbol
for
each
of
the
128
possible
ASCII
characters,
including
‘fill
characters’
and
‘control
characters’
(i.
e.,
carriage
return,
line
feed)
which
do
not
other-
wise
generate
printed
symbols.
While
in
this
Full
Monitor
Mode,
the
unit
will
print
the
symbols
for
carriage
return
and
line
feed,
but
will
not
execute
these
mechanical
Oper-
ations
at
the
times
they
are
called
for
in
the
text.
Instead,
the
teleprinter
will
completely
fill
each
line
with
the
maximum
number
of
characters
permitted
and
then
automatically
perform
a
carriage
return
and
a
line
feed.
This
mode
of
operation
is
most
useful
for
generating
compact
copy
and
greater
utilization
of
total
printing
area.
To
preserve
the
original
format
of
the
text
(in
terms
of
line
width
and
spacing
between
paragraphs),
the
user
may
engage
the
Special
Full
Monitor
Mode.
In
this
mode,
not
only
are
symbols
printed
for
each

each
with
its
own

for
input,
are
currently
available
in
the
AH

of
teleprinters.
The
particular
board
installed
in
any
given
machine
is
specified
at
the
time
of
ordering
and
should
be
properly
adjusted
to
conform

Messages
transmitted
to
the
teleprinter
are
in
the
form
of
on/off
pulses
sent
on-line
in
rapid
suc-
cession
(Serialized,
or
Serial,
Data)
according
to
a
specified
signaling
code
arrangement.
In
current
widely-used
codes,
5,
6,
or
8
on/off
bits
signify
a
given
character
or
function.
The
teleprinter’s
logic
circuitry
must
decode
these
sequences
of
bits
to
produce
an
intelligible
printout.
Standard
codes
which
can
be
accepted
by
current
AH
Series
machines
are:

Each
character
and
function
received
by
the
teleprinter
is
represented
by
a
series
of
current
or
no-current
time
intervals
on
a
neutral
DC
current
loop.
Current
flowing
on-line
is
referred
to
as
a
‘mark’,
while
a
no-current
condition
is
termed
a
‘space’.
(In
Polar
DC
systems,
‘mark’
and
‘space’
conditions
are
determined
by
the
direction
of
current
flow.
In
audio
communications
systems,
a
shift
in
the
frequency
of
the
tone
on
the
line
determines
‘mark’
and
‘space’.)
One
of
the
principal
codes
used
by
the
telecommunications
industry
is
the
5-Level
CCITT
No.
2
code.
In
5-Leve1
encoded
characters,
each
character
or
function
is
defined
by
at
least
7
on/off
units—
one
start
pulse,
one
stop
pulse,
and
five
bits
(or
levels)
which
determine
the
character
or
function.
Figure
1-3
illustrates
the
transmitted
character
‘E’
in
this
code.
The
start
and
stop
pulses
synchronize
the
message
receiver
with
the
transmission
site,
informing
the
receiver
of
the
start
and
finish
of
each
character.

Again,
start

this
code
uses
eight
bits

to
define
a
character

while
bit

the

may
be
changed
through
the
Speed
Control
Switch,
which
selects
any
of
the
three
crystals
installed
in
the
unit.
Power
to
the
unit
MUST
BE
TURNED
OFF
when
changing
from
one
speed
to
another.
See
Chapter
3
for
instructions.
CAUTION:
Each
crystal
corresponds
to
a
different
‘Baud
rate’
(a
quantity
directly
related
to
printing
speed).
Alternative
speeds
may
be
obtained
by
changing
the
crystals
(located
on
the
unit’s
Driver
Board).
Consult
the
following
chart
to
select
the

GENERAL
This
section
provides
instructions
for
the
installation
of
your
Series
AH
Teleprinter.
Be
certain
to
follow
all
‘Notes’
and
‘Cautions’
described
in
the
following
pages,
as
they
are
provided
for
your
safety
and
for
the
protection
of
your
machine.
When
reference
is
made
to
the
physical
location
of
various
component
parts,
the
tele-
printer
is
considered
to
be
viewed
from
the
front,
or
operator’s
position.
No
special
tools
are
required
to
correctly
install
the
unit.

UNPACKING
AND
INSPECTION
When
removing
the
unit
from
its
shipping
carton,
all
instructions
and
cautions
which
might
appear
on
the
outside
must
be
observed.
The
unit
is
enclosed
in
a
protective,
dust-proof
plastic
bag
which
is
surrounded
by
a
shock-
absorbing
material.
This
packaging
material,
including
the
carton
itself,
should
be
saved
in
the
event
that
the
unit
must
be
returned
or
forwarded.
Upon
removal,
the
teleprinter
should
be
thoroughly
inspected
for
any
damage
which
might
have
occurred
while
the
unit
was
in
transit.
If
any
damage
is
evident,
it
should
be
immediately
reported
to
the
transportation
company.
NOTE
If
the
teleprinter
is
not
to
be
put
into
operation
until
some
future
time,
it
should
be
repackaged
in
the
original
packing
materials.
Storage
temperatures
may
range
from
32-150°F
(0-66°C),
at
any
altitude
up
to
10,000
feet
(3048
m)
above
mean

INSTALLATION
LOCATION
Since
the
Series
All
Teleprinter
has
an
unusually
low
operating
noise
level,
it
may
be
installed
without
special
enclosures
or
sound-absorbing
material.
In
fact,
it
is
not
recommended
that
any
padding
or
cushioning
material
be
placed
under
the
unit,
as
this
could
constrict
air
flow
through
j
the
ventilation
ports
located
underneath
the
machine.
"
The
unit
may
be
placed
on
any
solid,
level
surface
of
sufficient
area
to
accommodate
the
physical
dimensions
of
the
unit,
but
should
not
be
situated
in
a
room
where
the
ambient
temperature
is
likely
to
exceed
113°F
(45°C)
while
the
machine
is
in
operation.
Likewise,
it
is
not
advisable
to
locate
the
unit
within
very
close
proximity
to
sources
of
direct
heat,
such
as
radiators
or
heating
ducts.
In
addition,
the
placement
of
the
teleprinter
should
be
convenient
to
an
AC
power
source
and
data
terminal
facility.
Data
reception
may
be
provided
via
appropriate
transmission
facilities,
in-
cluding
telegraph
lines,
telephone
networks
and
radio
channels.

General
Every
Series
AH
Teleprinter
is
equipped
with
a
power
cord
which
extends
from
the
Rear
Bracket
Assembly
adjacent
to
the
fuse
holder.
This
cord,
7
to
9
feet
long,
meets
the
electrical
specifications
of
the
geograph-
ical
area
in
which
the
machine
is
to
be
operated.
One
end
of
the
power
cord
is
normally
ter-
minated
in
a
three-prong
male
plug
for
con-
nection
to
an
external
AC
power
source
meeting
the
specifications
outlined
on
the
model
data
plate
affixed
to
the
right-hand
side
of
the
machine.
Units
designed
to
operate
from
a
230
VAC
power
source
are
not
usually
terminated
with
a
plug.
In
this
and
other
cases
in
which
no
plug
15
provided,
the
installer
must
provide
one
of
proper
configuration
for
connection
to
power
receptacles
in
the
user’s
area.

Changing
Operating
Voltage
Your
machine
has
been
wired
to
operate
from
either
a
115
or
a
230
VAC
power
source,
50
to
400
Hz.
Check
the
Status
Card
attached
to
the
machine
to
ensure
that
the
machine
has
been
wired
to
meet
the
voltage
requirements
of
your
area.
If—for
whatever
reason—the
operating
voltage
of
the
unit
must
be
changed,
the
installer
must
gain
access
to
the
power
supply
transformer
within
the
cabinet.
To
do
this,
follow
the
instructions
outlined
in
the
later
entry
entitled
Internal
Access.
To
change
the
operating
voltage,
remove
the
transformer’s
protective
plastic
cover
by
loosen-
ing
its
two
retaining
screws
and
sliding
the
cover
while
lifting
upward.

CAUTION
If
a
teleprinter
equipped
for
audio
signal
use
is
connected
to
a
DC
source,
serious
damage
to
the
input
board
will
result.
No
damage
will
occur
if
the
re-
verse
connections
are
made;
however,
the
teleprinter
will
be
inoperative
after
AC
power
is
applied,
and
the
Circuit
Alarm
lamp
will
light
to
signify
an
open
circuit.
The
teleprinter
is
designed
to
operate
nor-
mally
from
any
DC
signal
line
current,
neutral
or
polar,
between
10
and
60
milliamperes.
However,
if
the
unit
is
to
be
operated
from
peripheral
equipment
have
a
higher
current
rating
than
60
milliamperes,
current
limiting
resistor(s)
of
proper
value
must
be
wired
in
series
with
the
DC
input
signal
line.
If
spec-
ified
at
the
time
of
ordering,
the
resistor(s)
will
be
factory-installed
on
the
input
printed
EWG
LUG
circuit
board.
Provisions
have
been
made
on
this
board
to
switch
different
resistors
in
series
with
the
loop
for
field
modification.
