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 analyzes, printer front panel keys, and communications ports to provide powerful functions, including multiple interfaces, previously not attainable with a single accessory module.
