CHANGE NOTICE ISSUE 2.1
Version SA2.0 or higher on power up are YEAR 2000 COMPLIANT.
To ensure year 2000 compliance, these GS8920 Printers ONLY print the time and date
using an internally fitted Option BR2 time and date chip. Time and date data is no longer
accepted from weight indicators connected to the GS8920. See pages A-10 and 3-4 for
further details.
CHANGE NOTICE ISSUE 05 OF THIS MANUAL
Methods of Clearing the TARE registers clarified. Information added to the manual
concerning the installation and use of the GS8920 Printer with the GS1650Mk3/v2
Multi-Range/Multi-Interval Indicator. These are manual change only. They apply to all
GS8920 models regardless of their software version.

PHYSICAL
MFast and Easy Installation. :-
1. Fit Option 02 EIA RS-232C or Option 05 20mA Current Loop Serial Output board to any GS Weight
Indicator and select ANY baud rate in the range 600 - 19200 baud and ANY parity.
2. Select the weight indicators C3 serial output with beg/end and block divide characters number 06.
3. Connect the GS8920 Printer to the GS weight indicator using the interconnecting cable provided, apply
power and start accumulating weight ! ( No messy switches and internal settings to worry about !) The
GS8920 AUTOMATICALLY determines if the input is EIA RS-233C or 20mA Current Loop and
AUTOMATICALLY determines the baud rate and parity settings and then sets itself to properly receive
the serial data.
4. Use GS8920 digital setup parameters to enhance the operation or the printout if required.
MCan be connected to most Gedge Systems digital weight indicators and other selected
digital weight indicator products.
MConnect any number of weight indicators to the GS8920 Printer via a simple low cost
multi - pole switch. The GS8920’s automatic error correction allows trouble free
switching of the serial input AND if a Gedge Systems weight indicator is used, the
indicator’s device number is printed on the ticket to identify the scale.

A Description and Overview of the GS8920.
A .1 Overview and Physical Description.
A .1 .1 Overview.
The GS8920 Ticket Printer forms part of the rapidly expanding GS family of non redundant intelligent
microprocessor based instruments designed specifically to satisfy the needs of modern industrial
weighing.
The GS8920 Ticket Printer incorporates the common thread running through all of the range of GS
products - it is versatile, intelligent, expandable and can be used in conjunction with pre-existing GS
digital weight indicator products as well as a range of other popular brand digital weight indicators.
In the above figure, the GS8920 Ticket Printer is connected to one GS digital weight indicator. The
indicator may be connected to a weighbridge or a platform scale or, in fact, any weighing device.
The GS8920 Ticket Printer may be connected to virtually any number of GS digital weight indicators
via a low cost multi - pole switch. The GS8920 includes software which allows simple switching of the
serial input line without causing an operational failure of the GS8920. Additionally, the GS8920 Ticket
Printer includes the GS indicator’s device number on the printed ticket and so allows the scale from
which the weight information was transmitted to be identified on the ticket.
As a standard security measure, access to the digital setup routines may be locked out at 3 levels by a
keystroke procedure, a remote user supplied keyswitch and an interlock in the rear connector which
may be wire sealed in place. Access to the security registers, the accumulated totals, the accumulator’s
material codes, the name table assignments and the Alpha Name table may also be locked out via a
user supplied remote keyswitch.
