1920
characters
(24 lines of 80 coll.rons). It operates either Half or Full Duplex, Scroll or Page
IT19de,
and
in
either
Character
or Block transmission mode. The terminal provides
text
editing and for-
matting capability, enhanced display and protected fields, full cursor control and addressing, and
cursor position
readout.
It also provides many prograrrmable
features
(down-Ioadable or keyboard-
loadable), . including comnunications speeds, wide
character·
display (24 lines x
40
columns), and
32
. functions. The modular "no toals" design enables operator replacement of malfunctioning modules.

CharacterIBlock Modes
In
Character mode, each character code
is
transmitted individually as the appropriate data key
is
pressed;
blocks may
be
transmitted
by
pressing the transmit keys.
In
Block
~ode,
keyed data goes
to
the
TELERA
Y display and
is
only transmitted
by
the
transmit functions.

Half/Full
Ot4>lex Modes
Full Duplex operation
is
used with Full Duplex type modems (Bell
103);
Half Duplex mode with Half
Duplex modems (Bell 202). These modes
are
selected
by
a rear
pG1el
switch.
Full Duplex Operation
When
the TELERAY
is
in
Character
mode
G1d
Full Duplex mode, keyed data
are
transmitted;
the
data
will
not go to
the
TELERAY display unless the remote computer echoes
it.
The Serial I/O Request to Send
signal
is
held
ON
in
these modes.
In
the Block
G1d
Full Duplex modes, keyed data goes
to
the
TELERAY
display
G1d

~
go to the Serial I/O port. Keyed data
is
transmitted
only
by
the
transmit functions.
Half Duplex Operation
If
the TELERAY
is
in
Character mode ood Half Duplex mode, a local copy
is
imaged
on
the screen as
items
are
keyed and transmitted. The Serial I/O Request to Send signal
is
asserted upon initiation of
keyboard data entry and negated following transmission
of
Line Feed or New Line code.
In
the
Half Duplex
CI'ld
Block modes, the Request to Send signal
is
asserted only during a
blocl<
trans-
mission. Keyed
data
goes only
to
the
TELERAY display and can
be
transmitted only by the transmit
function.
Local/Remote Modes
In
Local mode
the
TELERAY keyboard and programmable functions
are
executed within the TELERA
Y.
No
data
is
transmitted and the Request to Send and
Data
Terminal Ready signals
are
negated. The Print
function will
operate
in
Local mode.
In
Remote

OPERATING
MODES
Wide/Normal
Character
Modes
The normal display
format
of
the
TELERAY
is
24 lines
of
80
characters.
Receipt
of an ESC m sequence
will
chalge
the
format
to 24 lines
of
40
characters
(Wide mode).
In
Wide mode
the
first
40
characters
of
each
line
are
expalded
to
twice
their
normal
size.
The display memory still
contains
80
characters
on
each
line
ald
all wrap and cursor positioning operations will
be
performed
accordingly. The TELERAY
will
remain
in
Wide mode Lntil an ESC I (lower cose
L)
or
a
Reset
to
Initial
State
is
entered;
either
will
return
the
format
to
24
lines or 80
characters.
Monitor
Mode
When
the
TELERAY
is
placed
in this mode (via keyboard switch) all control
characters
including ESCAPE
and
Delete
are
treated
as
data,
entered
into
the
display memory, and displayed
in
the
form shown
in
Table
3. This mode allows
the
TELERAY
to
be
used as a line monitor and also allows
entry
of
control
characters
for subsequent block transmission.
New Line Mode
This mode
is
selected
by a
rear
palel
switch.
In
New Line mode
the
receipt
of
the
New Line
character
causes
both
a
Carriage
Return
and a Line
Feed
to
be
executed
by
the
terminal.
The New Line
character
can
be
selected
as
either
the
LF
character
or
the
CR
character
by
on
additional
rear
panel
switch.
Pressing
either
the
CR
or
LF key will
cause
the
cursor to go
to
the
first
collXT1n
of
·the
next
line
in
New
Line mode. When
the
TELERAY
is
not
in
New Line mode,
the
Line

Carriage
Return
commands
are
treated
as
separate
functions.
Right
Mcrgin Wrap Mode
When this mode
is
selected
by
the
rear
palel
switch and
data
is
entered
in
the
80th
column
of
any
line,
the
cursor will
automatically
be
positioned
in
the
first
collXT1n
of
the
next
line. A cursor
right
function from
column 80 will also couse
the
cursor
to
go
to
the
first
column of
the
next
line. This "wrap"
can
cause
a
scroll
to
occur
ar
can
couse
the
cursor
to
go
to
the
top
line (depending on
the
condition
of
Scroll/Page
mode) if
the
cursor was
in
the
24th line. .
If
Right
Margin Wrap mode
is
not

These modes
ore
selected
by
the
keyboard switch legended "Scroll."
In
Scroll mode (down position),
attempts
to

Protect
Mode
The TELERAY will
enter
Protect
mode
!..pon
receipt
of
an ESC W
sequence
and will leave
Protect
mode
when
it
receives
an
ESC X. These
sequences
may
come
from
the
keyboard, a programmable function,
or
from
the
Serial I/O. The fields which
are
to
be
protected
must
be
defined
before
the
TELERAY
is
placed
in
Protect
mode
(see "Fields"). The cursor
cannot
be
placed
in
protected
fields nor
can
these
fields
be
modified
in
Protect
mode.
All
field modifier
characters
(within
protect
fields
or
not)
are
protected
•.
The
Clear
functions will
erase
ooly Lnprotected
data.
-
In
Protect
mode, scrolling,
editing
functions,
and
columnar tabs
are
disabled. The
first
nonprotected
character
position to
the
right
of
each
protected
field becomes
the
tab
stop
for tabbing
operations.
In
Protect
mode,
the
protected
fields
are
not
transmitted;
a single FS
code
is
substituted
for
them.
Keybocrd Lock Mode
In
the
Keyboard Lock mode, all keyboard
entered
data
are
discarded. The Keyboard Lock mode is
entered
by
an ESC b
sequence
from
either
the
keyboard
or
the
Serial I/O. The Keyboard Unlock
sequence,
ESC
c,
is
accepted
only from
the
I/O
port.
The
Interrupt
key
on
the
keyboard may
be
pressed
to
unlock
the
keyboard manually. The Keyboard Lock
mode
is
automatically
entered
during any
extended
time
operation
(such
as
Print). Upon completioo
of
these
operations
the
keyboard will
be
unlocked.
5
Disable/Enable Display Modes
When
Disable Display mode (ESC e)
is
entered, subsequent
data
from
the
keyboard, or from one of
the
functions,
or
from Serial I/O port, will not go to
the
TELERAY display. The
data
will be routed to
the
programming
area
for one of the programmable functions,
to
the
peripheral port,
or
to
the
serial port, as
appropriate, but will not go to
the
display portion of
the
TELERAY. Control codes (for example:
Clear
Screen) will
not
be
executed
in
the
terminal but will be merely passed
on
to
the
appropriate point. \
When
the
Enable Di'splay (ESC f) mode
is
entered,
the
TELERAY returns to normal. The Disable Display mode
will allow
the
remote
computer to download
the
functions
in
the
TELERAY without interfering with
the
operator.
A typical download sequence might include
the
following:
A.
Lock keyboard
(ESC
b)
B. Disable display
(ESC
e)
C.
Define function
(ESC
U
II)
D.
'The
message which
is
to
be
loaded into
the
function
E. End definition
(ESC
V)
F. Enable display
(ESC
f)
G.'
Enable keyboard (ESC c)
The Disable Display mode
is
also useful within
the
function programming
to
exclude portions or all of
the
function programming from going to
the
TELERAY screen. For example: If
the
functions were
programmed to
initiate
sequences for control
of
the
Teledisk, operator may not want these sequences to
go to
the
display
area
of
the
TELERAY but would wont to transmit them to
the
Teledisk. These function
definitions would then contain a Disable Display
in
the
beginning of
the
programming and an Enable
Display
in
the end of
the
programming.
OPERATOR
COMMUNICATIONS
Fields (
Dim, Blink, Underline, Inverse Videa and
Protected
fields may be established
on
the
TELERAY
in
any
combination. These fields are
started,
chonged, or ended
by
entering a special
character
(field modifier)
in
the
TELERAY memory. Any combination of field modifiers occupy only one display memory location.
The field modifiers,
are
entered
in
the
memory using
the
sequence
ESC
R followed
by
the
modifier code
(see Table 4).
All
data
following
the
field modifier
in
the
display (until
the
end of
the
80
character
line)
will have
the
characteristics
shown
in
Table 4.
To
change or
terminate
a field before
the
end of
the
line,
another field modifier
character
is
entered
in
the
memory.
Field modifiers
are
displayed os
either
a space or os a
"11"
depending
on
the
position of
the
rear
panel
switch.
On
transmission of
data
in
unprotected mode, a space
cod~
will be substituted for
the
modifiers
in
Protect
mode, an FS (File Separator code) will be substituted for
the
protected
field.
Undesired field modifiers can be removed using
the
Search and Clear modifier function
(ESC
S).
This
function will
search
the
display
in
the
forward direction until a field delimiter
is
found, will remove
that
modifier
ald
position
the
cursor
in
the
modifier position.
In
Protect
mode, those modifiers
in
protected
fields will not be removed. The search will "wrap" from
the
end to
the
beginning of
the
display; if no
modifier
is
found,
the
cursor will be repositioned
on
the
starting
location.
Bell
An"
audible tone, approximately
100
msec. duration,
is
produced on
receipt
of
the
BEL

or
the
Serial
I/O
interface.

Interr~t
The Interrupt switch may be used
by
the
operator
to
abort any operation currently underway and return
the
terminal to a ready
state.
When
performed
the
interrupt will "ring"
the
bell;
the
contents of
the
dis-
play memory will not
be
changed
by
this function.
Break
When
pressed this switch will
generate
a
250

PROGRAMMABLE FUNCTIONS
The TELERAY contains
32
programmable functions.
Any
ASCII
sequence may be assigned
to
these func-
tions; 527 characters of memory
are
available
to
be used by
the
functions
in
any combination. The func-
tions can be used to
store
forms, control sequences, answerback messages. A function should not call
itself or coli another function. Functions can be initiated
by
an appropriate
ESC
sequence (see below);
the
first eight also can be initiated
by
keyboard keys assigned to them. Other keyboard arrangements with
additional keys assigned to
these
functions
are
available, consult factory for details.
Use
of
the
Progranmoble
FUlCtiClnS
The functioos
will
be initiated
by
either the appropriate keys
on
the
keyboard (first 8) or may be initiated
by
3-choracta
sequence -
ESC
T followed by
the
function number. The function number must be a two
digit number from 0 I through 32, inclusive. Both digits must be used (e.g., 0I, 02,
etc.)
If
an illegal or
undefined function number
is
given
the
sequence will be ignored.
When
a function
is
initiated,
the
ASCII
sequence stored
in
the function memory
is
treated
by
the
TELERAY
as
a keyboard input. Control
characters
end
ESC
sequences will be executed end/or
transmitted
as determined
by
the
operating mades.
Progranming
the
Progranmoble
Fln:tiClnS
Programming of
the
functioos will be initiated
by
the
sequence
ESC
U, followed
by
function number. The
programming
of
eny function will be terminated by
the
sequence
ESC
then
V.
If
the definition sequence
is
given for a function which has been previously defined,
the
old program will be discarded end a new one
entered.
As
the
functions
are
being programmed,
the
progrtllTl
data
will also be executed. For example: if
the program sequence contains a Clear Page function
the

INTERFACE
The peripheral port provides
O'l
RS232 serial asynchronous
interface
for a printer or other peripheral
device. Following a peripheral-on command (DC2) from
the
keyboard or
the
1/0
interface,
data
are
transmitted
to the peripheral port as received or as
entered
en
the
keyboard. The peripheral baud
rate
will
be
set
to
the
1/0 baud
rate,
either as
set
by
rear
ponel switches or
as
changed
by
ESC
sequence (Table
2),
for concurrent printing. A peripheral-off command (DC4) will
tum
off
the
peripheral
interface.
Any displayed data can also be
transmitted
to
the peripheral port
in
"block" fashion
by
pressing
the
Print
key. All
data,
including
protected
fields (with space
characters
substituted for field delimiters),
are
transmitted
at
the
peripheral baud
rate.

the
Transmit
message function transmits
the
data
from
the
first
ETX
preceding
the
cursor (or Home),
to
the cursor position.
An
ETX
(displayed as "EX" but not transmitted)
is
entered
at
the
cursor positioo before transmission.
With
the
rear

in
MONITOR
mode will
be
transmitted
(but not executed).
Buffet"ing
Block transmission from
the
Teleray can be suspended
by
a DC3 from a sending device. A DCI code will
cause transmission to resume. Block transmission
is
aborted if any
character,
number or control code pre-
cedes the resume command. A Busy/Ready mode can be
selected
to permit
the
Teleray to suspend
data
entry
from a computer equipped to
detect
and decode
the
proper commands. The mode
is
enabled
in
the
Teleray when an ESC h command
is
received.
When
this mode
is
enabled the Teleray sends a
DC3
command (Busy) when its input buffer
is
10
characters
from full.
When
the Teleray buffer is
10
characters
from empty a
DC
I (Ready) command
is
sent to the computer to resume
data
transmission. Once enabled
this mode can only be disabled
by
an
ESC
g (reset to initial state) command
or
if
power to the Teleray
is
shut
off.

CURSOR
MANIPULATlON
Basic Moves
The cursor can be moved one position up, down, right,
left
or
to
home (line one, column one), using either
the
non transmitting keyboard keys or
by
using
the
sequence:
ESC
and
A,
B,
C, 0 or H respectively.
Backspace will move
the
cursor one
left;
the space
character
one
character
to
the
right (destructively).
line
Feed moves
the
cursor one down;
Carriage
Return places
the
cursor
on
the
left
margin (also,
see
New
Line mode).
Mcrgin Wraps
When
a-
cursor
left
function
is
initiated with the cursor
in
the first column,
the
cursor will move to
the
80th column of
the
preceding line (assuming
the
80th column of
that
line
is
not protected).
When
a cursor
left
function
is
initiated with
the
cursor
in
the
Home position,
the
cursor moves to the 80th column of the
24th line. A one up function
in
the
top line, will position
the
cursor
in
the
same
column, Line 24. The
actions taken
on
the
right and bottom margins depend
on
the
condition of
the
WRAP and SCROLL modes
as
previously described.
Cur.scr Address Write
md
Read
The cursor can be moved directly
to
any line-column coordinate using
the
sequence ESCape Y - line code -
eolumn code. The sequence
ESC
a wiii cause
the
TELERAY to transmit its cursor position
in
that
order.
The line code
O"1d
column code for each position
is
given
in
Table I.
An
illegal coordinate
in
on
addressing
sequence will be ignored; this allows
the
cursor to be moved to another line without changing
the
column
or
to
another column without changing
the
line.
Tabs
The TELERAY accommodates a
total
of
16
columnar
tab
stops. A columnar
tab
stop con be
set
in
any
column position
by
moving the cursor
to
that
position and pressing
the
Tab Set key,
or
by
the
sequence
ESC
F. Any existing tab stop can be cleared
by
moving
the
cursor to
that
position and pressing
the
Tab
Clear
(shifted Tab Set) key. The
Clear
Tabs function '(ESC
G)
clears all Tab Stops simultaneously. Tab
stops do not occupy display positions.
When
the Tab/Back Tab key
is
pressed,
the
cursor moves forward or backward, respectively,
to
the
next
tab
stop (which movement may include right or
left
margin wrap,
as
appropriate).
In
Protect
mode,
the
columnar tabs
are
ignored and
the
character
position
to
the
right of each
protected
field
acts
os
a
tab
stop.
If
no
tab
stops have been
set
the
cursor will
not
move.

MACHINE
ORGANIZATION
The T
eleray
consists of a display
cabinet
and an optional
detached
keyboard
module. The display
cabinet
contains a Monitor module, Power Supply module
and Logic module. These modules
are
accessible without using tools for
exchange and/or repair. The Teleray instruction manual graphically
illustrates
module
replacement.
.
The Module Signal Flow and Cabling Diagram describes
the
signal flow between
modules. All connectors used
are
keyed to prevent
incorrect
insertion. The
ribbon
cable
used
is
symmetrical,
the
cable
may be reversed end-to-end. Pin
numbers on
the
cables
are
provided
in
each section.
