Overview
The Printronix General Purpose Input/Output (GPIO) module is an optional
accessory for SL5000r/T5000r thermal and P7000 line matrix printers.
It enables the printers to interface with an external device such as a label
applicator system.
Simple printer menus allow for programming three of the eleven pre-defined
interface signals (seven outputs, four inputs) to select particular polarity or
logic functions that can meet practically all typical print/apply requirements or
be compatible with practically all the features available on other
manufacturers’ external I/O interfaces. This allows easy migration of
Printronix thermal and line matrix printers to new or existing systems. Field
interface is accomplished through an industry standard 50-pin D-type
connector.
GPIO is available as a factory option or field installable kit that also includes a
mating connector for field interface, installation instructions, and operation
manual.
Although there are seven pre-defined outputs and four pre-defined inputs, the
GPIO module actually contains a total of eight inputs, eight outputs (all inputs
and outputs are optically-isolated), and four relays. By using Printronix GPIO
Manager software, these can all be custom configured and be mapped in
conjunction with Printronix proprietary functions such as ODV analyses,
printer front panel keys, and communications ports to provide powerful
functions, including multiple interfaces, previously not attainable with a single
accessory module.
