CIRCUITRY ACCESS
The display unit cover must be removed to permit access
to the Motherboard into which the Terminal Control cards,
interface cards, and optional accessory cards are installed.
Removing the display unit cover opens a line voltage safety
interlock switch, which automatically cuts power when the
cover is removed. The switch actuator (located, in the top,
left-rear corner) can be pulled up to permit Terminal
operation with the display unit cover removed.
No.
Contents-A comprehensive explanation of the 4023. It
includes operation, characteristics, servicing, adjustment,
circuit description, and parts lists.
Optional items used with the Terminal are explained in
separate manuals.
INTRODUCTION
The 4023 Computer Display Terminal interfaces between man and computer by permitting inputs through an
integral keyboard and providing a display of computer
output data. In addition, the Terminal can relay data
bi-directionally between peripheral devices and a computer.
An Interface Unit must be installed in the Terminal and
connected to the computer-either directly or through a
modem (modulator-demodulator)-to permit information
interchange. The Terminal has the ability to have copies
made of its display, via a Hard Copy Unit.
INSTALLATION
I
WARNING
I
Dangerous voltages exist in the display unit area when
the line cord is connected. Servicing should be done
only by qualified technicians.
SELECTING STRAPPABLE OPTIONS
Strappable options are movable wire straps located on
circuit cards inside the display unit, Figs. 1-3 and 1-4 show
the strap option locations. These straps provide options for
the operator and programmer and can be set at the user site
by qualified technical personnel. The circuit cards (seven of
them) plug into the Motherboard. See Fig. 1-5 for card
locations on the Motherboard.
1. Do not remove or install circuit cards while the
Terminal power is on.
2. The cards must be installed in the order shown in
Fig. 1-5; otherwise, heat is not dissipated properly.
GENERAL
Installation consists of desk-mounting the Terminal,
selecting the proper operating voltage and fuse size, setting
the desired strap options, and connecting the Terminal to
the computer. These steps are discussed in the following
paragraphs.
MOUNTING THE TERMINAL
Desk-Mounting consists of simply setting the Terminal
on a desk or other surface. The air vents on the bottom and
sides should be kept free of obstructions to permit air flow
through the unit.
A dimensional drawing is provided in Fig. 1-2 as an
installation aid.
REV. S, Dl:C. 1974
The positions of the straps are dependent upon computer and program requirements, and in some cases, upon
user preference. The location and description of the
movable strap options for the Keyboard Interface, Control,
Timing, and Basic Data Communications Interface cards are
shown in Figs. 1-3 and 1-4. Information on cut-strap
options can be found in Section 2 of this manual. The
Optional Data Communications Interface (021-0112-00) is
to be installed in P8. The Standard Data Communications
Interface (021-0111-00) is installed in P9. Detailed strappable option information for these two interfaces can be
found in their respective manuals.

AC Power Sources and Requirements
This Terminal is designed tooperate from either a 110
or 220 volt nominal line voltage source that 'has a
frequency of 48 to 440 Hz. In addition , any of three voltage
ranges for 100 Vac or four voltage ranges for 220 Vac may
be selected. Voltage , current and power requirements are
listed below .
VOLTAGE, CURRENT, AND POWER REQUIREMENTS
This Terminal is intended to be operated from a
sing le phase, earth, referenced power source having
one current carrying conductor (neutral) at ground
(earth) potential. Operation from power sources
where both curre nt-carrying conductors are live
with respect to earth (such as phase-to-plyase on a
multiphase system, or across the legs of a 117-234
single phase three-wire system) is not recommend ed because on ly the line conductor has overcurrent
(fuse) protection within the instrument.

Most of the keys are used only for entering data and are
designed for single key entry, dual key entry, and triple key
entry. Most are familiar with typewriter keys. The 4023
keyboard shown in Fig. 1-9 is equipped to perform as an
input for ASCII or TTY codes. ASCII characters are shown
on the key caps and are represented by the key code as
follows.
Letter keys
Unshifted provide lower case; shifted provides upper case.
Number keys
Unshifted provides numeral; shifted
provides character shown on front
surface of key.
Control Character
keys
Control character keys that transmit control characters are: ESC,
TAB (HT), BACKSPACE (BS), LF,
and RETURN (CR). When these
keys are pressed, the appropriate
control character is transmitted regardless of SHI FT key position.
All others
U nsh ifted (lower) or Shifted
(upper) characters as shown on top
surface of key caps.
TTY LOCK KEYBOARD ENTRY. Lower case letters
(alpha) characters cannot be transmitted when the TTY
LOCK key is depressed, regardless of the position of the
SHIFT key.
REPEAT ENTRIES. Character transmission occurs when
a key is pressed. If the key is held down, a 0.5 second delay
(approx.) occurs, after which the character is repeatedly
entered at a 10Hz rate. If CTR L or SH I FT is used with a
character key, the original selected code continues to be
transmitted as long as the character key is held down, even
if CTR Lor SH I FT are subsequently released.
CONTROL KEYS. The following keys do not directly
enter characters for transmission, but control operation of
the keyboard or Terminal. Some of them are used
independently, while others are used in combination with
other control keys or character keys.
®I
PAGE-ERASE INPUT When pressed alone, causes all
unprotected data stored in Terminal memory to be erased, and the
cursor moves to the home position.
This function is normally used with
formatted displays. When pressed
while SHI FT is held down, performs a PAGE function. The
memory is cleared, the logic is set
to initial condition, and the cursor
moves to home.
CTR L
Causes letter keys to transmit control characters if CTR L is held
down before the letter key is pressed. It may be used in conjunction
with SH I FT and a character key to
form a control character.
SHIFT
Performs no function when used
alone. When held down, it causes
some keys to enter a shifted
character while the character key is
pressed. It is also used in combination with CTR L and some
letter keys for entering control
characters.
TTY LOCK
Causes letter keys to transmit the
TTY character set, regardless of
position of SH IFT key.
The
following are not transmitted:
\
} ;
'"
BREAK
Generates a BREAK signal, which is
sent to the interface unit. Any
resulting interrupt signal is interface
dependent.
RUBOUT
Not a control key but a character
key. When pressed, the RUBOUT
(127 10 ) character is transmitted.
Use of this key is program
dependent.
FUNCTION PAD CONTROLS
This useful, dual-purpose group of controls is located to
the right of the keyboard. They provide control over data
transmission, editing, cursor positioning, and reset functions. With the NUM LOCK key pressed, these keys
function as a numeric pad to aid in entry of numeric data.
RESET
REV. APR 1974
A multiple purpose key that performs the following (depending on
operating configuration):
1. BI inks the cursor; cursor quits
blinking when key is released.

LCE signal description in "Definition of Line Titles" in Section 6.)
DEL L
DEL C
Pressing this key without SHI FT
causes the character at cursor location to be deleted. All characters to
right of cursor move left one position. A NU L character resides at
the right-most character position on
the line. This function also repeats.
Pressing with SH I FT causes a
Delete Line function. The line
where the cursor resides is lost and
replaced by the line immediately
below. All other lines below also
move up one line. The line vacated
by the last line moved up is filled
with NUL characters. This function
also repeats when the keys remain
held down.
SEND
ENTER
Pressing this key without SHI FT
initiates the Enter transmission
sequence. Pressed with SHI FT
initiates the Send transmission
seq uence. (See Operation Descriptions for explanation of Enter
and Send.)
CURSOR (Direction
Shift) Keys
A group of four non-encoded keys
that provide directional movements
of left, right, up, and down for the
cursor. A momentary push moves
the cursor one character or line
position in the direction indicated
on the key cap. Holding the key
causes the function to repeat.
HOME
Moves the cursor to the home
position. Home is the first character
position of the first line. (Also
terminates a buffer transmission.)
NUM LOCK
Pressing this switch enables function Pad keys to be used as a
numeric pad. Specific numeric
inputs provided by individual keys
are embossed on the front surface
of the key caps. NUM LOCK must
be pressed a second time to restore
normal Function Pad Controls.
6. Clears a Make Copy request (will
not terminate a copy in progress).
7. With formatted displays, holding
RESET down enables data to be
keyed into a protected field: Alpha
characters can also be keyed into a
non-alpha field.
8. With formatted displays, pressing ERASE TO END with RESET
held down, causes erasure of data in
a protected field from the cursor
position to the end of that field (or
the end of the line).

OPERATING MODES
GENERAL
The 4023 is both a transmitting and a receiving device.
Standard interface hardware provides Full Duplex only.
Full or Half Duplex can be achieved by use of an Optional
Data Communications Interface. Data can be transmitted to
the computer directly from the keyboard, from the
keyboard via the Terminal buffer (memory), or from an
optional auxiliary unit. Data received by the Terminal can
be displayed, or can control other functions in the Terminal
or at auxiliary units.
Data transmitted to the computer can be echoed back to
the receiving circuits by the computer, the modem, or by
selecting Local Echo at the interface unit. Under Local
Echo conditions, data from the keyboard or auxi liary unit
is simultaneously sent to the computer and the 4023
receiving circuits. Printable characters from the computer
enter the Terminal memory and are displayed. The computer can write anywhere on the screen regardless of fields.
The LOCAL/ON LINE switch must be in the ON LINE
position to communicate with the computer. The LOCAL
position allows the Terminal to operate independent of the
computer. Local operation permits keyboard or auxiliary
unit data to be written on the display or otherwise
executed by the Terminal.
The Data Entry Modes are: Direct Entry, Buffer Entry,
and Buffer Form Fill-out Entry. They function as follows:
(Table 2-4 in Section 2 provides a brief description of data
transfer in DIRECT and BUFFER.)
cursor movement past the last line on the display. When ON
LINE, the Direct Entry Mode can operate in full or half
duplex (depending on the interface unit used). Placing the
LOCAL/ON LINE switch to LOCAL causes all keyboard
data to go directly to the auxiliary device (such as a mag
storage unit). The data is not sent to the Terminal memory
for display, unless a local echo condition exists.
BUFFER ENTRY
This mode is set when the DIRECT/BUFFER switch is
set to BUFFER. Keyed data is stored in memory and is
displayed, allowing text editing before data entry. Buffer
Entry Mode is used for either non-formatted or formatted
operations. When no Field Attribute Codes (FACs) are used,
the entire message is transmittable. Video is displayed white
on black background with normal intensity. Pressing either
the ENTER or SEND key initiates the buffer transmission
sequence. As in the Direct Entry Mode, the destination of
data is determined by the position of the LOCAL/ON LINE
switch.
ENTER KEY ENTRY. Pressing the ENTER/SEND key
without SH I FT causes an ETX code (A Message Separator)
to store in memory (if display is non-formatted) at the
cursor location. Storing the ETX in memory causes a
rectangular marker to be displayed at the cursor positiurl.
The cursor moves rapidly back through the text, seeking
either a start of text message (previous Message Separator)
or the home position, then sends the stored message.
Transmission of data continues until the cursor reaches the
ETX code, at which time the Terminal sends an End Code
and performs a carriage return. (The End Code can be
strapped to be any desired control character. Standard strap
setting is for a CR code.)
NOTE
The fol/owing is a discussion of operation of the
standard Terminal. Strappable options and other
options can modify the description.
DIRECT ENTRY
Placing the DIRECT/BUFFER switch to DIRECT sets
the Direct Entry Mode. This mode is interactive by
character (similar to Teletype). Destination of data depends
on the position of the LOCAL/ON LINE switch. In the ON
LI N E position, data entered from the keyboard (keyed
data) is sent directly to the computer. Data from the
keyboard is not sent to the Terminal memory for display
unless the computer echoes the data, or the modem or the
interface unit supplies local echo. Roll-up occurs with a
®
Fig. 1-12 is an illustration of the 4023 display during a
typical 4023/computer entry interchange using the buffer.
Assume that the cursor was originally at the home position.
The operator keys into the Terminal memory the first line,
edits if necessary, then presses the ENTE R key. The cursor
moves rapidly back through the text, searching for a
previously stored Message Separator or the home position,
in this case, the home position. Data entry then begins at
the home position. Data entry continues to the ETX code
that was stored when the ENTER key was pressed, at which
time the 4023 sends an End Code and performs a carriage
retu rn fu ncti on.
The first character of the computer response is an LF
(line feed) code that positions the cursor down one line.
Thus combined with the carriage return executed by the
Terminal, the cursor is positioned to the first character
position of a new line. Computer response continues ...

Buffer transmission illustration.
If the software does not provide an ETX at the end of
this message, the operator may store a Message Separator
by simultaneously pressing the RESET and CR keys. The
CR stores but is not executed . This provides a Message
Separator between the computer response and the following buffer entry. As with the ETX code, the storing of CR
displays a visible retangular block. This Message Separator
marks the beginning of text for the next message to be
entered by the operator.
SEND KEY ENTRY. The SEND key can also be used to
initiate buffer entry. However, it will not store a Message
Separator; the message to be sent is controlled by existing
Message Separa\ ors. As when the E NTE R key is pressed,
buffer entry is v om the preceding Message Separator (or
home). If no Message Separator was previously stored at the
cursor location prior to pressing SEND, cursor movement
continues to the last cha racter position of the last line . The
Terminal then transmits an End character and executes a
carriage return.
USE OF MESSAGE SEPARATORS. Figure 1-13 shows
how the Message Separators can be used to input specific
data. Assume that the string of data shown is a computer
1-14
response to the Terminal. The operator wishes to input back
to the computer a specific line (or lines) . Using the cursor
position keys, the cursor is positioned to the beginning of
the data that is to be input, at which point a CR is stored by
simultaneously pressing RESET and RETURN. Next, by
using the cursor position controls , the cursor is positioned
at the end of the data to be input. Pressing ENTER causes
an ETX to store. The data, bracketed by the two message
separators (CR and ETX), is then transmitted.
BUFFER FORM FILL-OUT ENTRY
Any Field Attribute Code stored in memory sets the
Buffer Form Fill-Out Mode . When Terminal logic receives
the US control character, logic is set to interpret the next
character received as being a Field Attribute Code (FAC).
This mode is normally used when inputting form information to the computer. Fig. 1-14 illustrates a form that might
be used by a bank . The illustrated square symbol that
precedes each data field symbolizes the position in Terminal memory occupied by the Field Attribute Code. The
Field Attribute Code identifies the data field that follows .
If no other field codes appear in the line, the .field extends
to the end of the line. When no field codes appear in a line

fields identified by the code for the ASCII "A" character
blank the line up to the next FAC, or the end of line .
NOTE
Note the character that appears in the character space
preceding each field. These characters represent the Field
Attribute Code and are not normally visible . However,
Fig. 1-14 illustrates the codes and the position in memory
that each occupies. Fields identified by the code for the
ASCII "N" specify that all data extending to the next FAC
(or to the end of the line, if no other field codes exist in the
line) as protected, non-transmittable data. The operator
cannot alter the data, (unless RESET is pressed). This data
is normally the form heading information that resembles
the source document. Those fields identified by the code
for the ASCII "@" character contain data that is transmittable and unprotected. Data in these fields can be
altered and transmitted. Both alpha and numeric data can
be input to these fields. Fields identified by the code for
the ASCII" A" character contain data that is transmittable,
non-alpha only. (Only those characters that reside in
columns 2 and 3 of the ASCII Code chart can be keyed into
a non-alpha field.) Alpha data cannot be entered into these
fields from the keybo~ rd unless the RESET key is held
down while simultaneously entering alpha data. Those
®

TRANSMITTING FORM FILL-OUT DATA VIA
ENTER. With the form displayed, the operator can key the
input data into memory, or change the input data already
displayed. If necessary, all input data can be cleared by
pressing the ERASE INPUT key , or just one input field can
be cleared (or part of an input field can be cleared by using
the ERASE TO END key). The operator can use the TAB
key to move the cursor from one input field to the next.
When all necessary inputs have been keyed into memory,
the operator can press the SEND-ENTER key (without
SHIFT).
The ENTER transm ission sequence is used for normal
form up-dating when FAC's are in memory. No ETX is
stored when ENTER is pressed. Thus, no matter the cursor
position, all input data can be entered . The cursor moves

backward through the text, seeking a previously stored
Message Separator or the home position, and the KEYLOCK indicator becomes lighted. When the system is ready
to accept the data, the cursor moves through the text,
causing transmittable data only to be entered to the
computer. When the cursor reaches another previously
stored Message Separator or the last line, last character
position, an End character is transmitted, and the Terminal
transmits the End character and performs a carriage return,
positioning the cursor to the left margin on the 24th line.
The KEY LOCK indicator goes out, signifying that the transmittable data has been entered .
TRANSMITT~NG FORM FILL-OUT DATA VIA SEND.
Pressing the SE~D key in Buffer Form Fill-Out Entry
performs functions similiar to the ENTER key, except that
all data (non-transmittable and transmittable) is input. The
Send transmission function in Form Fill -Out can be used
for programming or for storing a newly generated form
onto a medium (such as a magnetic storage device) for later
call-up .
1-16
NOTE
In Form Fill-Out operations, previously stored
Message Separators are honored.
NUL SUPPRESSION
NUL characters reside in memo ry when the Terminal is
turned on, or the screen is erased. NU L's are not transmitted during an Enter or a Send transmission sequence.
This causes the transmitted message to be "compacted". If
the memory has been entered to a storage medium, it will
be read back in its "compacted" state. In other words,
because the NU L's were suppressed when reading to the
storage medium, no spacing is provided for later read-back
to the Terminal. Therefore, where spacing between lines
and characters is important (such as with formatted
displays), use SP (SPACE) characters as required. The SP
character can be transmitted, and when read back to the
Termir'lal, will provide the necessary spaces between lines
and characters.

ALPHABETIC LISTING
ACCESSOR I ES. See Table 2-1.
ADDRESS. A display position with reference to a grid
of 80 by 24 characters with the 0, 0 address being at top
left (also known as the first character position). Address is
synonymous with Position Cursor and Read Cursor
functions.
ARMING. Certain functions at the Terminal require a
control sequence whose first character "arms" the
Terminal, permitting the next character to perform a
function other than what it would do if the Terminal were
not armed. ESC is normally used as the arming command.
The execution commands are listed under "Character
Effect on Terminal." In addition, accessory devices may use
other execution commands as explained in the accessory
device instruction manual.
BIT 8 AND BIT 9. See Table 2-3.
BLINK CURSOR STRAP. See Strappable Options,
Table 2-12.
1920 characters. The Terminal uses 262 non-interlaced
horizontal sweeps of video to generate the display. Of the
262 lines, 22 lines are blanked. This allows 10 video sweeps
per character line, thus a character line can be referred to as
10 video lines. To allow spacing between lines of alphanumeric characters, only 7 of the 10 video sweeps are used
(lower case uses 8 video lines). Some of the optional ruling
characters use all 10 video sweeps, in addition to filling in
the space between ruling characters with video. This
permits solid lines to be displayed for charts, graphs, and
forms. Fig. 6-3 in the Circuit Description shows the relation
between the character generator and the video sweeps. The
upper left-hand corner of the display is illustrated, with
character position 0, 0 being the home position. The crt
electron beam sweeps video line 0 of character line 0,
retraces, then sweeps video line 1 of character line 0,
displaying information as commanded by the logic and
video circuitry. The beam retraces and continues sweeping,
displaying video one sweep at a time. Note that Fig. 6-3
provides an ill ustration of character generation for both
alpha and optional ruling characters.
CHARACTER MATRIX. Characters in columns 2
through 5 of the ASCII code chart use a 5 x 7 dot matrix
pattern to provide write information to the Terminal logic
and video circuits. The lower case and optional ruling
characters use a 5 by 8 dot matrix. Th is matrix is "spread"
to a 7 x 10 dot matrix for ruling character generation.
BUFFER. See Display Specifications, Table 2-5.
BUFFER TRANSMISSION. See Transmission, Buffer.
CARRIAGE RETURN. Return of cursor to the left
margin occurs on receipt of CR or ESC FF; on receipt of
LF (if it is strapped on Keyboard Interface Card to also
perform a carriage return); by initializing or pressing
PAGE-ERASE INPUT key or HOME key; or when wraparound occurs when spacing past the last character position
in a line.
CHARACTER EFFECT ON TERMINAL. Terminal recognizes characters contained in ASCII code, except for
those not listed in the Code Effect Table. All alphanumeric
and ruling characters except space and delete (RUBOUT)
result in character writing and subsequent spacing. Space
does not write visibly but is stored in memory and causes
spacing; delete causes neither writing nor spacing. Control
characters and control character sequences are decoded and
perform specific functions as shown in Table 2-2. Additional use of control characters or control character
sequences may be made by accessory devices connected
through circuit cards to the Terminal minibus.
CHARACTER GENERATION. The standard Terminal
contains 24 lines of 80 characters each, for a total of
2-2
CHARACTERS PER DISPLAY. See Display Specifications Table 2-5.
CHARACTERS PER LINE. 80 Characters per line.
CHARACTER SIZE. Limits determined by width and
height adjustments. Nominal size, 80 by 120 mils.
CHARACTER TRANSMISSION. Depending upon the
operation selected, the code for ASCII or TTY characters
can be transmitted from the keyboard in response to a key,
in response to a SHIFT and key combination, or in
response to a CTRL SHIFT and key combination. RUBOUT sends the code for DEL. BIT 8 is sent normally high,
or as determined by the data communication interface in
use. The Motherboard can accept any eight-bit combination
from accessory units for transmission to the computer.
CHARACTER TRANSMISSION OF FIELD ATTRIBUTE CODES. See Field Attribute Code Transmission.
CHARACTER TRANSMISSION IN READ CURSOR
OPERATION. A sequence of characters is transmitted to
the computer in response to a control character sequence
from the computer. See Read Cursor Operation for details.
®
Characteristics-4023 Service
CHARACTER TYPE. The standard character type used
on the Terminal display is ASCII. Optional ruling characters
can be provided to display orthogonal characters for
drawing charts, graphs, etc. If the Terminal has the optional
rulings ability, the Terminal initializes with ASCII selected,
and returns to ASCII in response to a Reset or Clear Page
function; program selection for ASCII or rulings characters
occurs in response to SI and SO, respectively (C N and Co
from keyboard).
CONTROL CHARACTER STORAGE. Control characters keyed in from the keyboard or sent by the computer are
not normally stored in Terminal memory; they are simply
performed. Control characters (other than ETX) that are
computer originated can never be stored. However, control
characters can be stored from the keyboard by simultaneously holding down the RESET key when keying in the
control character. RESET does not prevent HT, VT, ESC,
FS, and US from being executed.
NOTE
CONTROL CHARACTER TRANSMISSION. Control
characters (excluding CR, NUL, and ETX) can be transmitted when stored in memory. When a control character is
stored in memory, its position is indicated by a displayed
block of about cursor size, at its respective position on the
display. CR, LF, and BS are not executed when entered
into memory with RESET. Only one-half of the control
characters can be displayed. If Bit 1 of the control
character is true, then the control character can be
displayed.
A superscript C
(and sometimes uS uJ precedes
an alpha to designate the simultaneous pressing of the
CTRL (and SHIFT) and character keys, when keying
control characters for the keyboard.

CHARACTER WRITING (KEYBOARD). The Terminal
has writing capability for all ASCII characters. Since TTY is
a subset of ASCII, TTY writing capability is included.
CHARACTER WRITING INHIBIT. See Keyboard Lock
Conditions.
CHARACTERS, LOWER CASE. Lower case ASCII
characters are accepted and written. Lower case letters
cannot be transmitted from the keyboard while the TTY
LOCK key is depressed.
CHARACTERS, RULING. An Optional character set
that, when selected by the proper code, permits ASCII code
to select specific ruling characters. This character set is
accessed by SO (C N from keyboard). The ASCII character
set is reselected by SI (CO from keyboard). See Fig. 2-2 for
illustration of available ruling characters.

appearance, its transmission, and its protection. The FAC
defines the field on the display and is stored in Terminal
memory in the first character position of the field. It is
protected from keyboard replacement regardless of the
protection status of the field it defines. (Simultaneously
pressing RESET will allow another character to be keyed
over the FAC. Edit functions such as delete line and delete
character will erase FAC's.) The field continues from the
location of the FAC until another FAC or the end of the
line is encountered.
FIELD ATTRIBUTE CODE TRANSMISSION. When
data fields are transmitted, the US control character
precedes the Field Attribute Code. US signals the program
that the next character is a Field Attribute Code.
1. Set DIRECT/BUFFER switch to BUFFER.
2. Key in from keyboard necessary information.
3. Position cursor at end of data to be transmitted.
4. Press SEND-ENTER key; response is ...
a. Message Separator (ETX code) is entered into
memory at the cursor location.
b. Cursor moves to the home position or previously
stored Message Separator.
c. Cursor moves at selected baud rate over data that
is subsequently transmitted.
d. At end of each line a CR is transmitted. IF's can
also be transmitted by placement of EOl LF GEN strap
on Control Card.
e. Cursor reaches Message Separator, transmits the
End character (CR is standard-can be strapped to be
2-4
FORMATTED DISPLAY. Displayed data that has been
specially arranged to resemble (for most purposes) a source
document, can be set up through use of Field Attribute
Codes. Field Attribute Codes are used to identify data in a
line. One FAC can identify from 1 to 79 characters (the
FAC occupies a character space in memory). Table 2-8
shows the available FAC's.
FULL PAGE FEATURE. A page full of data can be
rapidly entered into memory and displayed by simultaneously holding down the PAGE-ERASE INPUT, SHI FT,
and any character key, then, while still holding down the
character key releasing the other two keys.
HARD COpy MODE. Permits copying of the Terminal
display memory by a Hard Copy Unit. This mode is
activated by a COPY switch on the Terminal keyboard, a
Hard Copy unit, or by program command (ESC cG).
®
Characteristics-4023 Service
HOME POSITION. Top left corner of display that
corresponds to the first character position on the first line.
Cursor moves to that position upon initialization and upon
receiving ESC F F. It also moves there by a Clear Page
function, Erase Input function, or by pressing the HOME
key.

KEYBOARD. 64/96 ASCII upper and lower case with
auto repeat for any keys held down for more than
0.5 second.
KEYBOARD LOCK CONDITIONS. The keyboard is
prevented from inputting to the Terminal buffer under the
following conditions:
1. A message from the computer is pending or is in
progress.
2. The cursor is positioned over a Field Attribute Code.
MESSAGE
Table 2-12.
END
STRAP.
See Strappable Options,
MESSAGE SEPARATOR. Storing the ETX or CR codes
in memory provides a "message separator" for data entry
purposes. Initiating an Enter sequence stores the ETX code
at the cursor location. Message Separators are not stored
when FAC's reside in memory. However, there are exceptions to this rule. See Table of Reset functions, Table 2-11.
MINIBUS (ALSO MOTHERBOARD). This board makes
identical signals available at each of the board-edge connectors. See Dictionary of Line Titles and Wire List in
Section 6 for details.
MONITORS. The 75 ohm monitor output connector is
located on the Terminal back panel and provides composite
video for monitors. The number of monitors to which the
Terminal can provide acceptable video depends on the type
of monitor, the distance to the furthest monitor, and the
type of connecting cable used.
3. The cursor is positioned in a protected field.
4. When attempting to enter an alpha character into a
non-alpha field.
LINE, CHARACTER. Consists of 80 character spaces.
Data lines are made of ten horizontal video sweeps; seven
for character ~isplay and three for spacing between lines.
Some optional ruling characters use all ten video sweeps for
character generati on.
LF DOES
Table 2-12.
CR
STRAP.
See
Strappable Options,
LINE FEED. Moves writing beam down one line. Occurs
upon receipt of LF from keyboard or program. Standard
Terminal configuration performs a line feed upon receipt of
a CR. LF can also be strapped to simultaneously perform a
CR. See both LF DOES CR and CR DOES LF straps in
Table 2-12.
LOCAL OPERATION. Off-line operation used principally for operator training, formatting of data, equipment
maintenance, and when data processing functions are with
Terminal auxiliary units only. Local operation is selected
by the LOCAL/ON LI NE switch at the keyboard, and
isolates the Terminal from the computer.
MEMORY SPECIFICATIONS. See Display Specifications, Table 2-5.
®
NON-ALPHA FIELDS. Fields into which only those
characters listed in columns 2 and 3 of the ASCII Code
Chart are normally entered. See ASCII Code Chart in
Fig. 2-2.
NUL'S. NUL control characters reside in memory in
those character spaces where data is not entered. NU L's are
skipped during transmission to decrease transmitting time.
Functions such as Clear Page, Erase, Input, Erase to End,
Delete Character, and Delete Line enter NUL's into
memory.
NUMERIC PAD. The cluster of 12 keys on the right of
the keyboard provide a 10 key numeric input pad. This is in
addition to their primary functions as explained in individual switch descriptions in Section 1. The NUM LOCK
key initializes the numeric functions; NUM LOCK must be
pressed again to re-establish the normal functions.

question; Direct, Enter Sequence, Send Sequence, Transmission, and Cursor Reading Transmission.
See Transmission,
RESETTING HOME POSITION. The Terminal resets to
home position (top-left of display area) in response to ESC
FF from the computer. Home position also occurs when
PAGE (Clear Page function), HOME, or ERASE INPUT is
entered at the keyboard.
ROLL-UP. Roll-up occurs in DIRECT with a line feed
past the bottom line of the display. All lines roll-up one
line, with the top line rolling off the page. A new line is
then available at the bottom on which to enter new data.
RULINGS CHARACTER SET. An optional character
set that provides 32 "ruling" characters for drawing charts,
forms, etc. This set is accessed by SO; SI reselects the
normal character set. RESET or PAGE from the keyboard
also reselects the normal character set.
2-6
SEND TRANSMISSION SEQUENCE. Similar to Enter
Sequence. Variations are:
TRANSMISSION, COMPUTER INITIATED. The computer can initiate transmission of buffer contents via one of
two sequences, Send All or Send Transmittable Only. Send
All is initiated when the Terminal receives ESC SO. All data
whether defined by Field Attribute Codes as transmittable
or not, is sent. Send Transmittable Only is initiated when
the Terminal receives ESC SI. Data defined by Field
Attribute Codes as transmittable, is sent, as is data not
defined by a FAC.
TRANSMISSION, CURSOR READING. Data is transmitted as a series of bytes in response to an ESC] from the
computer. The sequence of transmitted data from the
Terminal is GS, X, Y, END. GS is the ASCII control
character that identifies the following two bytes (X and Y)
as cursor position data. X is the code for the character
position in a line (0 through 79 + 32) and Y is the line
number (0 through 23 + 32). End is the character that
marks the end of transmission and is usually strapped to be
CR.
®
Characteristics-4023 Service
TRANSMISSION RATE. Interface dependent. See
documentation pertaining to the specific interface unit.
Also see Data Transfer Rate.
WRAP-AROUND. A Terminal feature that causes an
automatic carriage return/line feed to be performed when
moving the cursor past the 80th character position.

BS command has no effect.
CI
Horizontal Tabulate-a format effector. In Buffer mode
or TAB key
with formatted displays, HT tabs the cursor one character
space beyond the FAC that describes an unprotected field.
Used to tab the cursor from one field (any field) into the
next input field. If no input field is available, the cursor
returns to the Home position.
When no Field Attribute Codes are stored {in D I R ECT}, HT
performs a non-destructive direct space, i.e. moves cursor
right one space.
LF (10 10 )
Line Feed
CJ
or LF key
Line feed-a format effector. In Buffer operations, LF
performs a line feed by moving the cursor down one line. It
does not affect the horizontal position of the cursor unless
strapped to give a CR with LF (see Strappable Options). An
LF past the 24th
lim~
will cause the screen to roll up one
line. If in Direct, LF's can be executed depending on mode
configuration (see Strappable Options).
Vertical Tab-a format effector. Performs a "back tab"
function-the reverse of the HT function. If no input field
is found, the cursor goes to the home position. Performs no
function in D I R ECT.
CR (13 1 0)
Carriage Return-a format effector. Moves the cursor to the
Carriage Return
first character position at the left margin. Can be strapped
to provide a line feed with carriage return, thus establishing
a new line at the left margin. Various effects to and from a
CR are provided by strappable options. Can also be stored

print video (except for blink) onto paper. Multiple copies
can be obtained under program control by commanding a
copy to be made and immediately following it with the
Read cursor command (ESC]). The action of making a
copy delays the reading of the cursor until the copy is
completed. When the Terminal responds with the cursor
location, the program can use this as signifying that the
copies is ready for another command.

STRAP OPTIONS
There are two types of strap options used in the 4023, Factory and On Site. Factory options are set at the factory and
include modifying the board by installing or removing circuit card runs. Factory straps are normally operating configuration
straps, that select the standard operation configuration when un-cut. On Site straps are movable wire straps located on the
circuit boards. These straps can be moved at the user site by qualified technical personnel.
The Strap Options Table gives the strap name, its function, its location on the board in respect to the nearest integrated
circuit, and its type (Factory on On Site). Listing of boards is by assembly number (A 1, A2, etc.), and the straps are
alphabetized for each assembly. The location of a specific strap on a board is indicated by a number in the IC Location
column. This number corresponds to the nearest integrated circuit to which the strap is located. The strap name is also
silk-screened on the board next to the strap to aid in locating the strap. The card location on the minibus can be found by
referring to Fig. 1-5.
WARNING
I
Dangerous voltages exist inside the display unit. Before attempting to change any strap, or remove any circuit
card for strap access, turn Terminal power off and disconnect the Terminal from the power source.
Some operating configurations require that more than one strap be set. The following information lists those operating

MAINTENANCE
GENERAL INFORMATION
I NTRODUCT ION
Beyond the need for occasional clea n ing of th e face of
the display and other outer su rfaces of the Terminal, there
is virtually no need for routine servicing of the Terminal. It
has no lubrication points, no air filter s, and (with the
exception of the crt) no vacuum tubes. The solid-state
components provide stable ope ration, with little need for
routil1e adjustment .
MOUNTING THE TERMINAL
OPTIONAL PEDESTAL
ON
THE
A pedestal, on which the Terminal can be mounted, can
be ordered from Tektronix, Inc. (PN 016-0568-00) .
Mounting the Terminal on the pedestal is 'tccomplished by
lift ing the Termin al over the pedestal and installing four
machine screws up through the pedestal top to fasten the
Terminal in place. Adjust the four feet to a convenient
position, and fasten the lock nuts.
SERVICING PROCEDURE
However, if a routine schedule and procedure is desired,
a one-year interval and the following sequence is recommended . The disassembly and assembly instructions con tained in this section should be referred to as necessary .
DESK-MOUNTING
Desk-mounting consists of simply setting the Terminal
on a desk or other surface. See Fig. 3-1. The air vents on
the bottom, sides, and back should be kept free of
obstructions.
1. Disconnect the line cord from the power source .
2 . Remove the top from the Terminal.
3. Using a vacuum cleaner, remove dust accumulation
from within the unit . Use a soft-bristled brush to loosen
dust that won't otherwise vacuum out. A soft cloth and a
mild soap and water solution can be used to remove any
really stubborn dirt .
4. Inspect the interior for broken leads, loose connections, heat-damaged components , etc. Correct as necessary.
Investigate the cause of any heat-damaged components.
5. Wash the face of the crt, using a soft cloth and a mild
soap and water solution .
6 . Perform the check -out procedure found in this
manual. Perform the adjustment procedure if the check-out
procedure indicates that it is necessary .
7. Put the cover back on the Terminal
8. Clean the outside of the Terminal, using a soft cloth
and a mild soap and water solution .
SOLDERED OPTIONS
Fig. 3-1 . Desk Mounting .
®
In addition to strappable options, there are some options
that can be selected by soldering or cutting soldered wires .

TROUBLESHOOTING INFORMATION
TROUBLESHOOTING PROCEDURE
Troubleshooting of the Terminal can be done best if the
various features of this manual are used to their fullest
advantage. These features and recommended usage are
listed here.
To troubleshoot the basic Terminal, remove all accessory
cards and the interface card. Then check operation by
doing the Performance Check. Stop where the Terminal
fails to respond properly, and troubleshoot the referenced
area, using schematics and associated descriptions. Replacement of suspected circuit cards is recommended as a fast
means of confirming suspicions. If the Performance Check
works satisfactorily in the basic Terminal, install option
cards and the interface card one at a time and repeat the
Performance Check until it fails. Then troubleshoot the
last-inserted option card and the circuits with which it
interacts.
CONTROLS AND OPERATION. This information
ensures operator understanding of the Terminal features
and operation.
CHARACTERISTICS. A complete explanation of the
Terminal capabilities is contained in the Characteristics,
along with explanations of how to put the capabilities into
use.
PERFORMANCE CHECK. This provides a rapid means
of checking for proper operation in a logical sequence
under normal equipment configuration. It can also be used
with the options and the interface unit removed, to indicate
operating status of the basic Terminal.
Obviously, not all troubles can be revealed by the
Performance Check or Adjustment Procedure. However,
they should prove beneficial in most cases, and should aid
in guiding a technician to the trouble area.
RECOMMENDED TROUBLESHOOTING EQUIPMENT
A
ADJUSTMENT. The procedure follows
sequence of adjusting the basic Terminal:

logical
CIRCUIT DIAGRAMS AND CIRCUIT DESCRIPTIONS. These diagrams and their associated descriptions
provide an understanding of Terminal operation on a circuit
as well as component level. The information contained
therein is essential to efficient location of trouble.
Log icE xtender
Card,
Tektronix
Part
No.
067-0659-00, is an efficient tool for circuit analysis. This
card can be used as an independent plug-in card to make all
minibus signals available to the technician, providing level
indicators for most of the lines. In addition, it provides a
feature for injecting high- or low-level logic signals into the
signal lines. The card can also be used as an extender for
other circuit cards, and then permits interruption of any or
all signals to the card which is attached to it.
COMPONENT LAYOUT ILLUSTRATIONS. These
appear on the aprons of their respective diagrams in Section
6 and can be used as aids for locating components.
Another extender card is available under Tektronix Part
No. 067-0696-00. This card can be installed into the
minibus to make bus lines available at test points, and can
also be used as an extender for cards installed in the
minibus.
INTERCONNECTING WIRE LISTS. A listing of cables,
jacks and plugs, as well as an explanation of their use, is
provided in the Diagrams section. Wire colors are also
provided, using the standard code for resistors.
A -20 V to +400 V dc voltmeter and a 10M Hz
frequency-response oscilloscope are recommended test
equipment for troubleshooting low-voltage and logic
circuits.
SEMICONDUCTOR INFORMATION. An illustration of
semiconductors appears in Section 6 just preceding the
diagrams, and can be used for pin identification. An
integrated circuit test clip is recommended for use in
troubleshooting the in-line integrated circuits, since it
makes their leads easily accessible.
WARNING

Dangerous voltages exist within the Terminal and
normal electrical safety precautions should be
observed at all times when working around exposed
circuits within these units.
REV. B. DEC. 1974
Maintenance-4023 Service
The Motherboard can be completely disconnected and
the supplies will still come up. However, when troubleshooting the power supply circuits, a resistive dummy-load
should be connected in place of the Terminal circuits. This
avoids accidental damage to other circuits in the Terminal.

PERFORMANCE CHECK/ADJUSTMENT
PERFORMANCE CHECK
GENERAL
This procedure (see Table 4-1) can be used under normal
operating conditions with all circuit cards installed. Because
some checks require that ON LI NE be selected, check that
the Terminal is not connected to a modem or computer.
Checks are referenced to a circuit card to permit rapid
evaluation of incorrect results. In event of an improper
response, recheck the step with all optional and interface
cards removed from the minibus to determine if the
Terminal is at fault.

ADJUSTMENT
INTRODUCTION
Adjustment of the Terminal is required only when it
ceases to properly perform its intended functions, or after
circuit repairs have been made to the power supply or to
the monitor circuitry. If an adjustment is to be performed
on a routine schedule, an interval of one year is recommended. Adjustment should be preceded by a thorough
cleaning and inspection as outlined in the Maintenance
Section. Adjustment should be performed in a +20°C to
+30°C environment and should be preceded by a twenty
minute warm-up period.
EQUIPMENT REQUIRED
The following equipment is required in this precedure:
1. Variable voltage source that has an output capacity of at least 2 A at 100, 110, or 120 Vac, or at least
1.25 A at 200, 220, and 240 Vac. The instrument
output should be variable to at least ±10% from the
stated value.
2. Single trace Oscilloscope with 10 mV vertical
sensitivity. Frequency response should include dc to at
least 10 MHz.
3. Voltmeter with a range of at least -20 Vdc to
+20 Vdc; accuracy within at least 1% on all voltage
ranges.
REMOVE THE TERMINAL COVER
At the back-left corner, remove the shield that covers
the transformer terminals. It is held in place by two screws.
Determine what voltage the transformer is wired for, by
comparing the connections against the diagram on the
surfaces of the switch (S1001) cover. If a variable ac power
supply is available, set it to the voltage for which the
transformer is wired. If the indicated supply is not
available, record the transformer wiring condition so it can
be restored upon completion of the adjustment procedure.
Then rewire the transformer connections to agree with the
available power supply. See wiring diagram for instructions.
Check the slow blow fuse (2 A for 115 V or 1.25 A for
230V).
WARNING
I
Dangerous voltages exist in the fuse and transformer
circuits. Keep the line cord disconnected while
working in these areas.
Check the +5 Vdc, 15 A fast blow fuse for proper size.
DETAILED PROCEDURE
Adjustments include Low Voltage Power Supply and
Monitor Adjustments.
4. Common Screwdriver. 1/8 inch tip, non-conductive, at least 10 inches in length, plus handle.
5. Screwdriver, Allen-Type, 3/32 inch tip-non conductive, at least 10 inches in length, plus handle.
1. LOW VOLTAGE POWER SUPPLY CHECK/ADJUSTMENT
a. After the preliminary procedure has been completed, connect the line cord to a variable power supply
source (auto transformer) which is set to the voltage for
which the transformer is wired.
ADJUSTMENT PROCEDURE
b. Turn the Terminal power switch ON and place the
LOCAL/ON LINE switch to LOCAL.
PRELIMINARY
Turn the Terminal power off and remove the line cord
from the power source.
I WARNING
I
Dangerous voltages exist within the Terminal. Normal
electrical precautions need to be observed when
working within the Terminal while the cover is
removed.
REV. B, SEPT. 1.976
c. Connect the voltmeter reference lead to the
ground Test point, TP 12. See Fig. 4-1.
d. Using a voltmeter that has 1.0% or better accuracy, adjust R258 to obtain +5.00 V at the +5 V test
point. Adjustment and test point locations are shown in

e. Measure the other power supply voltages as listed
in Table 4-2. Test points are shown in Fig. 4-1. Record
all voltages in Table 4-3. (Make duplicate copies of
Table 4-3 for future use.)
f. Using the test oscilloscope, check that ripple
voltages do not exceed those values given in Table 4-2.
g. Change the variable power source to 10% below
the center value for which the transformer is wired.
h. Measure and record the supply voltages, again
using Tables 4-2 and 4-3. Then check the ripple of each
supply.
i. Change the variable power source to 10% above the
center value for which the transformer is wired.
j. Again measure and record the supply voltages,
again using Tables 4-2 and 4-3. Then check the ripple of
each supply.
k. Analyze the results. All voltages should be within
the specified values. The differences between voltages at
center line and either high or low line should not show a
regulation larger than that specified in Table 4-3.

INDENTATION SYSTEM
Replacement parts are available from or through your local
Tektronix, Inc. Field Office or representative.
This mechanical parts list is indented to indicate item
relationships. Following is an example of the indentation system
used in the description column.
Changes to Tektronix instruments are sometimes made to
accommodate improved components as they become available,
and to give you the benefit of the latest circuit improvements
developed in our engineering department. It is therefore
important, when ordering parts, to include the following
information in your order: Part number, instrument type or
number, serial number, and modification number if applicable.
12345
Assembly andlor Component
Attaching parts for Assembly andlor Component
Detail Part of Assembly and/or Component
Attaching parts for Detail Part
If a part you have ordered has been replaced with a new or
improved part, your local Tektronix, Inc. Field Office or
representative will contact you concerning any change in part
number.
Change information, if any, is located at the rear of this
manual.

Name & Description
Parts of Detail Part
Attaching parts for Parts of Detail Part
Attaching Parts always appear in the same indentation as
the item it mounts, while the detail parts are indented to the right.
Indented items are part of, and included with, the next higher
indentation. The separation symbol - - - • - - - indicates the end of
attaching parts.
Attaching parts must be purchased separately, unless otherwise
specified.
FIGURE AND INDEX NUMBERS
Items in this section are referenced by figure and index
numbers to the illustrations.
ITEM NAME
In the Parts List, an Item Name is separated from the
description by a colon (:). Because of space limitations, an Item
Name may sometimes appear as incomplete. For further Item
Name identification, the U.S. Federal Cataloging Handbook H6-1
can be utilized where possible.
