The capability to operate in parallel means that the same communication lines are connected to
each DATANET-30, both are receiving the same incoming data, and either can transmit on any
circuit. The programs control which DATANET-30 is to transmit on which line.
The DATANET-30 With a GE-115 System
The GE-115 is ideal as a remote input/output terminal connected by communication lines to a
central computer system.
It
can be taken off-line and will perform as a card processing system.
As a remote terminal to a larger computer, it provides direct access to the larger system with-
out the media conversion otherwise often required.
For example, a GE-115 can generate an
interrupt at a distant computer, and read in a program request followed by data to be processed.
When the larger computer has performed the requested tasks, it transmits the data to the GE-115
to be printed or punched into cards.
On a voice grade line, card reading speed is 125 cards per minute minimum, card punching speed
is 85 cards per minute minimum, or 95 lines per minute minimum on the line printer. Printer
speeds can increase
if
printed lines are not a full 136 characters in length.
The Compact Card System offers a choice of: two memory sizes, one card reader, two card
punches, and one line printer.
The system can be tailored to fit most punched
card center
requirements.
For additional information, refer to the manuals on the GE-115 Computer System.
DATANET-760 Keyboard/Display Terminal System
The DATANET-760 is an alpha-numeric display system that provides rapid, real time communi-
cations with a computer from local or remote locations.
It
uses a cathode-ray tube for displaying
information, and enters data via the keyboard.
For use with the General Electric Compatibles
200, 400, 600 and DATANET-30 processors, it provides convenient entry and display of data or
requests, direct transmission to the computer, and receipt, storage and presentation of responses.
Data may be completely assembled and verified before it is sent to the computer. Changes,
additions, or deletions can be made to existing records in the computer file, by displaying the
data on the screen, and typing in changes on the keyboard. Hard copies of display data may be
generated when optional page printers are installed.
SYSTEM CONFIGURATION.
The DATANET-760 System consists of a Display Controller cabinet
and a number of remotely located Display Terminals.
The Display Controller is capable of
communicating with a central computer system via a telephone data set or by direct connection.
For additional information refer to the manual on the DATANET-760 system.
