GPIO Manager
Introduction
This chapter describes the Printronix GPIO function available for the
Printronix SL5000r/T5000r series Thermal printers.
NOTE: Only limited GPIO support is available for Line Matrix printers. Please
contact the Customer Support Center for information before ordering
Line Matrix printers with GPIO.
GPIO is both hardware and software. The hardware is the I/O board to be
mounted in the printer , and the software is the GPIO Manager. The GPIO
hardware is a printed circuit board containing optically isolated inputs and
outputs as well as relays. The GPIO software is both a printer resident GPIO
event parser and a PC-based GPIO manager that allows the user to define
how the general purpose I/O hardware should behave for the given
application.
NOTE: Certain GPIO features in the printer can only be enabled by a special
security key, described in Table 9 on page 220 and Table 10 on
page 229.
