Conversational
Display
Terminal.
Basically,
this terminal
is
the
120

defined
as
equipment
CC535-A
or
it
is
the
208/230

50
Hz type
defined
as equipment
CC535-B.
Both
of
these two types
are
functionally
identical
and

The terminal
acts
as a remote message

operating
primarily
with-
in
a central processor
controlled
telecommunications system. The terminal provides
standard
teletypewriter
I/O
functions
and
as such may serve as a
replacement
for
teletypewriter

An output channel
is
contained
in
the
terminal
to
enable
use
of
an
optional printer
to
obtain hardcopy
of
displayed messages.
This manual contains three
sections.
Section I defines the equipment functions
and
specifications.
Section
II
explains
the

and
describes basic
operating
procedures. Section III contains information
pertaining
to
programming including

SECTION I
GENERAL
DESCRIPTION
The Conversational Display Terminal (Figure 1-1)
is
configured to operate
as a video display, telecommunication, remote terminal
capable
of transmitting
and receiving messages
on
either
leased or
dial
telephone lines. It
is
designed
primarily for telecommunications under program control of a central processor.
The terminal provides
an
operator with composition versatility not possible with
conventional teletypewriter terminals and operates quickly and
relatively
noise-
free as compared to a teletypewriter
terminal.
The Conversational Display Terminal
is
expressly designed for telecommunications system and program compatibi
Iity.
The
basic equipment (see foreword)
is
ready for immediate use
at
any terminal location
which provides an
EIA
Standard RS-232-C
modem
(modulator/demodulator)
equivalent
to the
AT
&T
103 series asynchronous modem. Options
available
to the basic configu-
ration allow connection directly to a Manual
COT
Data Access Arrangement or acous-
tically
to any telephone (see
"Options").
Transmit and
receive
telecommunications
with the terminal are performed
via
the
modem
in
a
bit-serial,
character-by-character
fashion without block message transfers. Figure 1-2 shows a typical
terminal/central
processor communications link e

TV
DISPLAY
MODULE.
The display portion of the terminal consists of a field
replaceable,
high
resolution, television display module which
accepts
composite video
from
the
char-
acter
memory and associated control logic. The basic machine displays 8 lines of
80
characters
on
a 15-inch
(38
cm)
diagonal,
rectangular
CRT
within a view screen
area
approximately
8-inches
(20 cm) high by lO-inches
(25
cm)
wide.
An
expanded
character
memory option (see
"Options",
this section) provides
16
lines of
80
char-
acters.
Display repertoire
is
the
USASCII
X3.4-1968
compatible set of 96 charqcters
plus three characters generated
from
function codes (see Table
1-1).
Characters
appearing on the display screen are dot formed by selectively unblanking positions
within a 5 x 9 dot matrix-during a normal television raster scan of 262 horizontal
lines. Nominally, the characters appear on the display
1/8
inch
(0.3
cm) wide and
1/4
inch
(0.6
cm) high. A cursor (entry marker) appears on the display screen as a
blinking underline dash to indicate the position where a
character
will display on
the screen. A full display of 8 or
16
lines of
80
characters occupies approximately
a 5 inch (13 cm) high and 9 inch
(23
cm) wide
area
of the viewing
screen.
The
dis-
play refresh rate
is
60
Hz.
640
CHARACTER
MEMORY.
A modular, metal oxide semiconductor (MOS) memory contained on one
cir-
cuit
card within the logic module stores 640,
7-bit
character
codes for display refresh
and input/output
data
storage. The circuits are designed
to
accept
an additional
640
character
memory card
as
a
plug-in
module (see "Options", this
section).
The
c
(
basic 640
character
memory provides storage for 8 lines of
80
characters on the
dis-
(
play
screen.
CONTROL LOGIC.
Controlling the internal functions of the terminal
is
the control logic
that,
in addition
to
timing and sequencing circuits, includes a 256 word,
la-bit,
MOS
read only memory (ROM) which is programmed with
the
necessary beam
blank/
unblank dot patterns for video formation of
all
displayable characters on the display
screen.
KEYBOARD.
The keyboard
is
the operator input
device
for
the
terminal 0
It
is
a functionally
complete module which supplies
7-bit
USASCII
codes and operator control signals to
the terminal's interface
circuits.
The keys are the magnetic reed
type.

one of the character or control function keys are depressed, the
7-bit
code for
that
particular key travels
in
parallel to the interface circuits which control
data
input
routing. Tables
2-3
and
2-4
show the code repertoires
available
from
the keyboard.
The keyboard contains a
common
teletypewriter key layout for displayable characters (
and control functions
except
for added operator convenience features:
1)
lQ-key adding machine type numeric cluster in addition to basic
numeral row.
2) Common teletypewriter function codes
available
by CNTRL +key
depression.
3) Frequently used communications and
edit
functions
available
from
their
own key in addition to basic C
NTRL
+key
operation.
Section
II
of this manual describes keyboard
data
entry and function operations
in
detail.
INTERFACE.
The asynchronous interface circuits control
all
data
routing within the terminal
and between the terminal and the communications modem. These circuits are
con~
tained on two
circuit
cards within the logic module.
The interface
is
designed to operate with communications signals compatible
to
EIA
Standard RS-232-C such
as
the
AT&T
103 series
data
sets, or
equivalent.
These type
modems
communicate word-by-word with
8-bit
serial
data
words (including
parity).
The interface communicates
at
manually adjustable transmission rates of
75,
110, 150, and 300
bits-per-second.
The circuits do
all
serial-to-parallel
and
parallel-to-serial
conversion, perform all
modem
control, and during transmission
perform the
data-clocking
function and parity checking (if
any).
Data and control function routing performed by the interface between the
keyboard, modem, control, and printer channel depends on the settings of the
transmission and printer control switches described in Section
II.
PRINTER
OUTPUT
CHANNEL.
An
output channel contained on the interface circuit card allows use of a
printer
to
produce hardcopy of displayed messages. Either page printout or instan-
taneous printout of
data
as
it
is
displayed
character-by-character
is
available
by the
printer controls included in the termina
I.
These controls
are
described in Section
II.

A printer may be used exclusively by one terminal or up to
eight
terminals may share
a single
printer.
This
is
possible since the printer output channel contains
printer-in-
use recognition circuits and operator indicators which signify if another terminal
is
using the
printer.

The terminal is designed
to
accept
a
character
memory expansion of 640
additional
characters thus enabling
16
lines of 80 characters on the
video
display
as
compared with the basic version with 8 lines of
80
character
spaces.
This
expan-
sion is merely a
"plug-in"
printed
circuit
card addition of a second
character
memory
card with interconnecting
cable
(Expanded Memory Kit, see Foreword). If this
option
is
used, the two
character
memory cards, being
identical,
are
fully
inter-
changeable.
Th
is
expansion is easi
Iy
added as
an
on-site
change if ordered by a
customer
after
receiving the basic Terminal.
INTERNAL MODEM
OPTION.
The Internal Modem Kit option supplies a communications modem within
the terminal and provides a
connector
panel which allows connection
either
directly
to
a Manual
COT
Data Access Arrangement or
connection
to
an
optional Acoustic
Coupler (see IIAcoustic Coupler
Option").
The Internal Modem provides Bell
103
A,
E, and F compatable operation in the
Originate
mode on switched
telephone
lines.
This modem
kit
consists
of
a "plug-inti printed
circuit
card with terminal
connector
panel
and required interconnecting cables (see Foreword). Figure 1-5 shows a
typical
communications system with Internal Modem in use with a Data Access
Arrangement.
