PREFACE
This manual shows
the
operator
how
the
TermiNet Printers are operated. Sections 1 through 5
describe what
the
controls and indicators do,
the
operation
of
the
keyboard,
the
loading
of
paper
and ribbon, and
other
information pertaining
to
the
operation and care-of
the
TermiNet Printer.
Because of
the
many communication systems
that
exist, no
attempt
is
made
to
show
how
the
TermiNet Printer may be used
in
a specific system. Consult your supervisor
or
application
specialist for special instructions on how
to
use
the
TermiNet Printer with
your
communications
system. Section 6
is
primarily for
the
application specialist who must know certain operating
characteristics
of
the
TermiNet Printer
in
order
to
understand how it should operate
in
your
communications system.
This manual covers
both
the
TermiNet
300
and 1200 Printers. Information
that
pertains only
to
a
specific model Printer
will be identified.
The term
"jumper"
will appear occasionally in
the
following text. Basically,
the
removal or
installation of a jumper
is
an optional wiring change
that
will change particular operating
characteristics of
the
TermiNet Printer. Most jumpers can be installed and removed by a TermiNet
Printer serviceman
at
the
TermiNet Printer site.
Because many TermiNet Printer
problems are simple and can be easily avoided
or
corrected
by
the
operator, read Section 5, "TAKING CARE OF YOUR TermiNet PRINTER," before calling for
service. You may avoid an unnecessary interruption
of
your
operation and an unnecessary service
call.
In
most
cases,
the
word
"Printer"
will be used instead
of 11TermiNet Printer" in
the
following text.

Introduction
SECTION 1
INTRODUCTION
Your TermiNet Printer
is
a high speed data
communications
printer
used primarily for
communicating with computer systems or
other
printers. The TermiNet Printer
is
compact for
operation
on
a desk
top
or
on
its optional Pedestal.
Operation
is
quiet compared
to
similar equipment.
The Printer can print and transmit information
that
is
received from its keyboard or from an external source
(for
example, a paper
tape
reader).
NOTE
For convenience, reference
to
the TermiNet
Printer,
in
most cases, will be "Printer".
Your Printer
will be one of
two
basic models; the
TermiNet
300
or TermiNet
1200
Printer (Figures
1-1
and 1-2). The TermiNet
300
and 1200 Printers print
maximum speeds of
30
and 120 characters per second
respectively.
The
KSR
(Keyboard, Send, and Receive) version of
the Printer has a keyboard similar
to
a standard office
typewriter. The
KSR
Printer can
print
and transmit
information generated
locally by the keyboard or a
local device (e.g., paper tape reader}.
It can receive
and print information from a remote terminal,
computer, or
other
communication device. ·
NOTE
When a
KSR
Printer
is
combined with a
recording and reading device such as a paper
tape punch and reader,
the
combined
configuration
is
normally called an ASR.
The SR (Send and Receive) version of
the
Printer has
no keyboard. The
SR Printer operates similar
to
the
KSR
except for
the
absence of the keyboard.
The
RO
(Receive Only) version
of
the Printer has no
keyboard and can print received information only.
Although this manual
is
written primarily for the
KSR
Printer,
the
SR and
RO
Printers operate
in
a
similar manner except for
the
major differences
previously explained.
The
general operating characteristics of the TermiNet
Printer are
as
follows:
PRINTABLE
CHARACTERS
All
of
the
94
printable characters
in
the
American
Standard Code for
Information Interchange (ASCII)
can
be
printed by the TermiNet Printer.
PRINTING SPEEDS
300
Printer,
the
standard
front
panel
RA
TE
switch
will select speeds
of
10, 15, and
30
characters per second (cps). An optional
speed
of
20
cps
is
available
as
a substitute for
one of the standard speeds.
1200 Printer, the standard
front
panel RATE
switch
will select speeds of
10;
30, or
120
characters per second. Optional speeds of 15,
20
or
60
cps are available
as
a substitute for
one
of the standard speeds.
HORIZONTAL CHARACTER SPACING
10 characters per inch (2.5 cm).
VERTICAL LINE SPACING
6 lines per inch (2.5 cm) with the LINE SPACE
switch in the
11111
position. 3 lines per inch (5.1 cm)
with
the
LINE SPACE switch
in
the
"2''
position.
PRINT LINE LENGTHS
300
Printer - 75,
80
or 118 print positions.
1200 Printer -
80
or 120 print positions.
COPY
The Printer
is
capable of handling up
to
a six-part

Operation
SECTION 3
OPERATION
SWITCHES, CONTROLS,
AND
INDICATORS
Figures 3-1, 3-2, and 3-3 point
out
the
locations
of
the
switches, controls, and indicators and explain
their basic functions.
AUDIBLE
INDICATORS
Beep
tone
each time a key
is
pressed.
High
pitch
tone
when ALARM indicator
lights.
High
pitch
tone
when INTERRUPT indicator
lights.
High
pitch
tone
indicating near end
of
line
and end of line. The
tone
will sound
at
print
positions 67, 72,
110, and 112 on 75, 80,
118,
and 120 print position Printers
respectively. The
tone
will also sound after
the
last print position
of
the
Printer.
NOTE
The
volume
of
all
the
audible indicators
is
adjustable by
the
serviceman
if
the
preset
volume does
not
satisfy your particular need.
KEYBOARD OPERATIONS
The keyboard
is
similar
to
that
on a standard electric
typewriter. The keyboard has a total
of
62
keys
including
the
space bar, and
is
capable
of
generating
all
128
ASCII characters. The keys are electronically
interlocked
so
that
it
is
not
possible
to
generate
two
or
more codes simultaneously. A beep
tone
sounds
each time a key
is
pressed (with
the
exception
of
the
SHIFT, LOK, CTL, and RPT keys). Because actual
printing may
not
occur
at
the
same instant you press
a key (as with
most
typewriters),
the
beep
tone
allows
you
to
maintain your normal typing rhythm.
For descriptions
of
the
Printer operation keys, see
Figure 3-5.

ESCAPE SEQUENCE
AND
CONTROL
CODES
GENERATING ESCAPE SEQUENCE CODES
By
momentarily pressing
the
ESC
(Escape) key and
then
momentarily pressing
the
appropriate related
key, an escape sequence code
is
generated (the
character
following
the
ESC
code
does
not
print).
The
ESC
key and its related keys are shaded
on
their
front
edges. The Printer can react
to
escape sequence
codes from
the
keyboard or received from a remote
source.
NOTE
To
generate escape sequence codes with
early production
300
Printers, press and
hold
the
ESC
key,
then
simultaneously press
the
related key. Release
the
keys.
GENERATING CONTROL CODES
To
generate a control code, press and hold
the
CTL
(control) key,
then
simultaneously press
the
desired
control function key. Release
the
keys. Most control
function keys are identified on their
front
edges.
DESCRIPTION OF ESCAPE SEQUENCE AND
CONTROL CODES
In
the
descriptions following,
"receipt"
or
"when
received" refers
to
codes received,
not
those
Renerated
at
the
keyboard or
on
local tape.
Recognition" refers
to
codes received
or
to
codes
generated
locally. The following
is
a list
of
codes
most encountered
in
the
average system.
NOTE
In
some cases, the codes are stored. There
is
no permanent memory in
the
TermiNet
Printer, and stored codes
will be lost if
power
is
completely removed from
the
Printer.
ESCAPE
SEQUENCE CODES
The
ESCAPE code
is
used
in
sequence (Escape
is
first
code) with
other
codes
to
accomplish
the
following:
ESC
0 (Zero) RDR REV - This
code
when recognized
causes an
optional reading device
to
reverse.
ESC

SECTION 6
TermiNet PRINTER
OPERATING CHARACTERISTICS
The
purpose
of
this
section
is
to
provide
application
specialists
with
detailed characteristics
of
the
TermiNet
Printers
to
assist
in
implementing
communications
between
TermiNet
Printers
and
other
printers
and
computer
systems. Because
this
section
is
technical
in
nature,
the
information
may
be
too
complex
for
the
experience
of
some
operators.
NOTE
For
detailed
information
on
referenced
jumpers
in this section, refer
to
Service
Manuals GEH-2185
for
the
TermiNet
300
Printer
and
GEK-36105
for
the
TermiNet
1200
Printer.
DATA
TRANSMISSION
AND
RECEPTION
The
TermiNet
Printer
is
an
asynchronous
transmitting
or
receiving device. All
transmitting
or
receiving
between
the
standard
TermiNet
Printer
and
any
other
device
is
carried
on
in
serial form.
INTERFACE
The
electrical interface
between a standard
TermiNet
Printer
and a communications
network
is
in
accordance
with
RS-232C.
The
TermiNet
Printer
can
be interfaced
in
various ways
if
the
interface
specifications are met.
The
following describes
the
standard
and
optional
interface circuits.

SPEED
Data transmission speed
is
variable
on
the Printer,
depending on the position of the
selector switch
on
the
control panel. The TermiNet
300
Printer
transmits, receives, and prints
at
a standard 10, 15,
or
30
characters per second. An optional speed
of
20
cps
is
available for one of the standard speeds. It can
be
optionally configured
to
transmit and receive
(but
not
print) at 120 characters per second.
The TermiNet
1200 Printer transmits, receives, and
prints
at
a standard 10, 30, or 120 characters per
second.
It can be optionally configured
to
operate
at
speeds of 15, 20, or
60
characters per second as a
substitute for one of
the
standard speeds.
The corresponding transmission rates for these
various character rates are
110
(109.95), 150, 200,
300,
600,
and
1200
baud.
CHARACTER
COMPOSITION
Each character
is
composed of one
start
bit, seven
data bits, a parity bit, and one stop bit (at a
110
baud
rate, two stop bits are used).
See Figure 6-1.

Operating Characteristics
TIMING CHARACTERISTICS AND
FILL
CHARACTERS
Because certain non-printing operations (for example, Line Feed) require a finite amount of time, data being printed
must be delayed so
that
it will
not
be lost when the non-printing operations occur. Also, an operation must be
delayed, such as motor off, so
that
characters
in
memory can be printed. These time delays can be provided
by
using
11
fill
11
characters.
In
general, a 11fi11
11
character can be defined as any character
in
the ASCII code
that
does
not
cause
an equipment action
but
takes time
to
process. The Time Delay and 11Fifl
11
Character Tables list those operations
that
require a time delay,
the
associated time, and
the
number of 11fill
11
characters
req1:1ired
if
used.
In
the following
text
of
this section, a description
is
given on how the Printers are used with the TermiNet Cassette
Accessory and Paper Punch and Reader regarding
fill characters. Many
of
the necessary delays are provided
automatically and some delays can be obtained by methods
other
than using
the
number of 11Fi11
11
characters
specified
in
the table.
NOTE
The following
text
shows various examples
of
how
fill
characters are used.
In
these examples, the following symbols will
be
used:

The
following chart summarizes
the
time interval and 11fill
11
character requirements for the TermiNet
300
Printer.
The
following
text
gives examples
of
how 11fill
11
characters are used.
NORMAL SINGLE LINE FEED
The time delay required from the
last character on a line until the first character on the next line
is
300
milliseconds.
This time includes
the
CR,
LF
characters and the time
to
decode the first character on the new line. Since
at
300
baud each character time
is
33.3 milliseconds,
300/33.3
equals nine character times for the required
300
millisecond
delay. To produce this delay, use six fill characters in addition
to
the CR,
LF
codes and the first character on
the
new line.

CONSECUTIVE LINE FEEDS
If
there are
to
be consecutive line feeds after a line of printing, a time delay of
350
milliseconds
is
required for the
initial double line feed and
67
for each additional line feed. The
350
millisecond delay may be provided by eight fill
characters (350/33.3 equals eleven characters
less
CR, LF,
LF)
and the subsequent
67
millisecond delay requires 2
fill
characters (67 /33.3 equals two characters).

Operating Characteristics
Should an operator
"get
ahead"
of
the
recording mechanism by typing while a space
is
being written, an alarm will
be generated. This
is
very unlikely for keyboard data
but
could occur for an answerback sequence. This alarm will
light
the
alarm lamp,
turn
off the motor, transmit a break, and sound the alarm. This action
is
for local data only.
Received data cannot cause this alarm, facilitating
the
use
of
Fill Characters for timing.
If
adequate
fill
characters are
not
included, received data may be lost (not copied on tape).
In Transparency
Data received in Transparency
is
recorded exactly as received. Therefore, no automatic spaces are generated and each
delay character must be followed by 3 Fill Characters (5 Fills after VT
or
FF). Delay time may
not
be substituted
for these
Fill Characters when recording incrementally.
Non-Incremental Rate
Magnetic Tape recording
at
1200 baud
is
done differently with
the
TermiNet 1200 than the TermiNet 300. Unlike
the TermiNet 300, operation with the TermiNet 1200 at 1200 baud
is
not
character dependent. Whenever
the
terminal
is
in
the
1200
baud rate position, and the A3 TCA
in
RECORD Mode, the TCA will move tape
at
the
proper rate for 1200 baud recording, regardless
of
the condition of
the
data stream except during VT
or
FF motion.
Data transmitted
to
the TermiNet 1200 should contain
all
fills required for printing, with
the
added condition
that
every
LF
code should be followed by 3 fills
or
24
msec.
of
time.
If
the Printer
is
receiving
the
transmission
in
Transparency
or
Standby,
then
3 Fills
or
24
msec. of time should follow each delay character except VT
or
FF
codes which must be
followed by 5 Fills
or
41
msec. Recording
is
not dependent on the state
of
the Data Set
Interface signals.
READING (Incremental
or Non-Incremental)
The A3
Model
TCA does
not
delay after every
LF
code when reading. An internal timer will cause delays
to
guarantee
the
minimum time required for the TermiNet 1200 operation. LF,
BS,
VT, and FF characters will be
separated by
300
msec. if
they
appear closer than this
in
the data stream. Timing for VT and FF will be
as
required
for proper operation
(closed Loop TCA
to
TermiNet). The TCA will always delay a full
300
msec. for MOTOR
ON
and
MOTOR
OFF (ESC
Hand
ESC
J). A strap
is
included
to
vary
the
timer. With the jumper
out,
the timer will run
at
430
msec., long enough for
all
codes. With the jumper in,
the
timer will run
300
msec., which
is
adequate for
all
codes except
MOTOR
ON. Fill Characters (additional 16 Fills) must be recorded after the MOTOR ON,
if
the
300
msec. timing
is
used.
If
the
Printer
is
in
Transparency, no delays will occur.
When the Printer
is
on
ON
LINE
or
STANDBY, the Data set Interface Signal Clear
to
Send
(CB)
must be present
to
read tape.
If a DC3
code or an Interrupt
is
received,
the
TCA will stop reading after the next character
is
read.
