CHAPTER 1
INTRODUCTION
GENERAL
Delta 5100 and 5200 (Figure I-I) make up a complete family of stand
alone Video Display Terminals. Basically, each Delta 5000 is a keyboard
and a visual display. The keyboard is used by the operator for
composing messages for transmittal to an external source. The
visual display is used by the operator during message composition
and also for displaying messages generated by an external source.
The Delta 5000's can economically be used for data retrieval, data
preparation, inquiry-response systems, batch terminals, and other
applications where a man-machine interface is important to the user.
PHYSICAL DESCRIPTION
Each Delta 5000 consists of a single unit housing a keyboard, a
display monitor and a controller. The assembly is 16 inches
high, 18 inches wide and 27 inches deep and weighs approximately
100 pounds. with the single unit construction, the user need not
find additional locations for more than one component of the
terminal where limited desk space is a requirement. Optionally
available is a Delta 5000 with a separate housed keyboard. Should
it be a requirement to have the display remote from the keyboard,
DELTA DATA SYSTEMS can fulfill this requirement.
FUNCTIONAL DESCRIPTION
The Delta 5000 has a display capacity of 80 character positions on a line
and 27 lines. Each character is made from a 7 x 9 dot matrix and
a video scanning technique is used to display information. This
7 x 9 dot matrix allows for an extremely readable character set
in either upper or lower case. Each Delta 5000 employs several
standard features which implement an effective interface between
operator and an external source, such as a computer, communications
line, or another peripheral device.
These features are as follows:
*
*
*
*
A familiar teletype/typewriter style keyboard.
The ability to blink selected information on the screen.
The ability to format information on the screen.
The ability to page information on the screen. (PAGING
is a unique innovation developed by DELTA DATA SYSTEMS
CORPORATION which permits the local storage and access
for the possible display of more lines of data than can
be displayed on the screen at one time).

The ability to address any portion of displayed data.
The ability to tabulate or jump the cursor to the start
of a variable data field in the Format mode.
Rapid cursor (position marker) movement in any direction.
Separate numeric portion of the keyboard for rapid
keyboard entry of numeric data.
DELTA 5000 FAMILY
The Delta 5000 family consists of Delta 5100, Delta 5200 and Delta
5300 which have the above described features. The unique features of
each terminal in the Delta family are as follows:
Delta 5100. Delta 5100 is software and plug-to-plug compatible with
a teletypewriter. Delta 5100 is characterized by asynchronous serial
communications in which data is transferred one character at a time
i.e., every character is transmitted as it is typed by the operator
and every incoming displayable character is displayed as it is
received. Operation may be in echo or half duplex mode. The
input and output signals are in accordance with EIA and CCITT
V
24 requirements and are USASCII coded. In addition to the
serial communications interface which is character oriented, a
parallel party line interface is optionally available which is
message oriented. This party line interface may be connected to
other remote peripherals. Also, optionally available for Delta 5100
is the block mode transfer capability which is in addition to the
character-by-character transfer.
Delta 5200. Delta 5200, in addition to providing character-by-
character transfers as Delta 5100, is capable of block (message
or memory) data transfers. With block data transfers, Delta 5200
is capable of manipulating data prior to transmission. This
allows complete editing of information on the screen prior to
transmission. Delta 5200 also has optionally available the party
line interface. An additional separately housed controller
(MultiTerm 2) makes Delta 5200 completely compatible with the IBM
2260/2848 Display Complex for cluster environment. An IBM 2701
Data Adapter Unit equipped with the IBM Terminal Adapter Type
III is required to interface the IBM System/360 with MultiTerm.
In addition., MultiTerm 2 requires a modem to interface with the
IBM System/360.
Delta 5300. Delta 5300 is a Delta 5200 with a separate controller
that is IBM 2265/2848 compatible. It is used in a stand Alone
environment.

OPTIONS AND PERIPHERAL EQUIPMENTS
Several options and/or peripheral equipments are available for the
Delta 5000. These include:
1. PARTY LINE INTERFACE. The party line interface allows
other peripheral devices and special interfaces to be easily
attached externally to the Delta 5000. The System's user will find
it extremely valuable in applications where he has to interface to
the Delta 5000 in a mode other than a communications mode. The party
line offers the Delta 5000 display terminal great flexibility.
2. LINE DRAWING. All the Delta 5000's can have the ability to do
line drawings. This enables the Delta 5000 to draw solid, vertical
and horizontal lines, intersections, corners and special symbols.
These line drawing concepts are extremely valuable in creating
forms for ease of operator identification. The form is something
personnel are used to working with and the Delta 5000's ability to put
this on the screen adds to the flexibility and capability of the
Delta 5000. Another unique application of the line drawing option is
in the process control field where on-line diagrams are required
for flow charting of processes.
3. 96 CHARACTER SET. This option adds a lower case capability
to the Delta 5000 units. The use of the 7 x 9 dot matrix makes the
lower case very readable. This has great applications in text
editing where it is important to see on the screen what is to be
placed onto the paper.
4. HIGH SPEED TRANSMISSION. The Delta 5000 has the optional
capability of serial communications at rates of:
Up to 2400 baud or
Up to 9600 baud - with 2K memory or less.
The above are all asynchronous data rates using internal or external
clocks and they are the maximum speeds within an option, lower speeds
remain available within a given option range.
5. PERIPHERALS. The following peripherals are capable of
operation with the Delta 5000.
Cassette Recorders
Printers
Acoustic Couplers
Modems
1-6

6. DIRECT MEMORY ACCESS. The direct memory access (DMA) is
optionally available when the party line interface option is used.
with this option, peripheral devices or a computer connected to the
party line may directly read from or transmit to the Delta 5000 the
entire contents of memory at a rate up to 500,000 7-bit characters
per second, asynchronous.
7. DUAL RS232 - This allows an RS232, RO Printer to be connected
to the Delta 5000. On hitting the "Print" button information will go
from the Delta 5000 memory to the printer, but not out to the
communications line. This option is available on Delta 5100 if the
block transfer option is included.

CHAPTER 2
PRINCIPLES OF OPERATION
BLOCK DIAGRAM DESCRIPTION
The function of the Delta 5000 as shown in Figure 2-1 is to serve as
the interface between the operator and a central processor (via
communication lines) and if the party line option is utilized with
other peripheral devices. To perform this function effectively, the
Delta 5000 must accept data from and transfer data to the operator,
the central processor, and if used, the peripheral device(s).
As shown in Figure 2-1, a common party line bus allows anyone of
these devices or a combination of (e.g., the keyboard and the
computer) may be used to initiate or control data transfers.
Thus, all I/O transfers to and from the Delta 5000 are processed
over the party line I/O bus. The accepted party line data is
checked for additions, deletions, and format changes by an I/O
control. While the inputting, outputting, storage, editing is
done in a binary code compatible with standard communications
line interfacing, the data is presented to the operator in English
alphanumerics. The operator is able to enter and edit data in
familiar terms. To perform these operations, the Delta 5000 utilizes
both digital and analog internal circuitry.
The input/output (I/O), editing, and storage (memory) operations
are implemented with digital circuits. The digital language employs
the American Standard Code for Information Interchange (ASCII) code
which uses a 7-bit data word. Chapter 6 shows the complete Delta 5000
ASCII code tables. The CRT translation and video section translates
the ASCII code to analog voltages and currents which drive the CRT.
The analog signals cause the English alphanumeric equivalents of
the ASCII code characters, which are stored in memory, to be
displayed on the CRT screen. Based on the screen display, the
operator can enter data, initiate editing operations, and control
the keyboard, which provides a 7-bit ASCII output code or.code
sequence for every key. Operational features, which. can be
performed by each Delta 5000 are described below:
BLINK (See Chapter 4 for details of operation)
The selective blink features permit the keyboard or an external
source to call attention to important information displayed on the
screen. Such information blinks on and off at a rate of approximately
tvlO times per second. The operator's eye is captured by the
blinking and he can take appropriate action to acknowledge receipt
of such information. The "Blink Start" character will cause all
information following the Blink Start to blink, until a "Space"
is detected or a "Stop Blink" character is detected or Carriage
Return. In the Format mode, blinking will also end where the
end of a variable field is detected. This means that if a
given word or a given set of numbers is required to blink, only
one character is required to both start and stop the blinking.

MEMORY
& EDIT

This reduces software and the amount of information required to
be transmitted over the communications line. Any position in
memory may be set into the Blink mode. Blink Start and stop
characters are stored in memory but not displayed.
The blinking characteristic is extremely important in applications
such as process control, computer aided education, airline departure
and arrival systems, law enforcement and stock applications. The
blink characteristic is an unquestionably valuable tool in bring-
ing the attention of the operator or user to specific information
on the screen.
FORMAT (See Chapter 4 for details of operation)
The Format mode is designed to simplify the man-machine interface.
The Format mode allows information to be put in a pre-established
format on the screen, with fixed data fields and variable data
fields. The "Tab" is used to position the cursor to the next
variable data field. When looking at a formatted screen, the
variable data fields may be identified by dotted underline. No
information can be written over a fixed data field when in the
Format mode. Clearing of the screen in the Format mode will
only clear the variable information, leaving the format on the
screen.
The format capability has great importance in inventory control,
invoicing and general.data entry systems. It is important because
the operator gets a clear picture of what is required in the way of
information and yet he does not have to worry about clearing this
information or transmitting this information to the computer. The
operator has easy access to the data fields.
The Format mode also has great capabilities in automatic test
systems and in Process Control where fixed header information is
entered onto the screen and then the variable unknowns are put
onto the screen as they are accessed. This allows for ease of
input, as "TAB" from computer will move cursor to next position for
entering data. This minimizes the need to do "cursor addressing"
and incrementing.
PAGING (See Chapter 4 for details of operation)
The Delta 5000 has a unique capability called PAGING. PAGING allows
the terminal to store more information than can be presented on
the display at anyone time. Through PAGE UP or PAGE DOWN operation,
the display can access all the information that is in the terminal
in one line increments, allowing the display to look like a
window looking over the entire memory. The PAGING concept will
allow the operator to store as much information as the memory
capacity at the Delta 5000 and then transmit a total memory or a
message at a time to the computer. All space to the right of a
2-3

Carriage Return does not require refresh memory storage. For
example, if the user has 3071 characters of memory and puts an
average of 20 characters on a line, he is able to have a total
of 153 lines of data stored at the terminal. He can look at
any of these lines, 27 lines at a time, make corrections and then
transmit the total information.
PAGING is a new concept not previously available in displays.
It allows the operator to store as many lines of data at the ter-
minal as required to use up the memory. The PAGING concept allows
the user to receive more than one display screen of information
at a time from a remote source and does not require a storage
device, such as cassette recorder to hold an extra number of
lines of reta. PAGING also allows the user to verify more than
just one screen of information prior to transmission, so that when
transmission does take place, more information may be passed back
and forth at one time, without the use of a Cassette Recorder.
The PAGING feature is valuable when working with lists of Bills
of Material or other lists where the page of data is not always
equal to the display size.
EDITING (See Chapter 4 for detailed operation)
The Delta 5200 has the ability to do complete editing operation. It can
insert or delete on a line or character basis. By placing the
cursor at various points on a line parts of lines, can be inserted
or deleted.
