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.
