General Purpose Input Output (GPIO) Port Applications
GPIO-equipped printers can interface with most external controlling devices.
Operational preferences can be stored for subsequent power-ups using the printer
menu, or via <STX>Kc commands. Functions and connections vary, as discussed
below.
Always wear a wrist strap and follow ESD prevention measures when handling
the GPIO or Applicator Interface Card. For specification information, reference
the printer’s Maintenance Manual.
GPI/O I-Class Mark II
Four dedicated inputs are available for control of printer functions. These inputs
require no external pull-ups, are designed to interface to open-collector outputs and
accept totem pole outputs from +4.5 to + 26 VDC. Optical isolators are available to
provide isolation. Two print control circuit examples are given below.
For direct inputs
Use the printer’s +5VDC and Ground to supply the devices interfacing to the GPI/O A
inputs.
For isolated inputs
To provide galvanic isolation for the GPI/O A inputs, remove jumper JMP 9 then
supply an external +5VDC source voltage to Pin 2, and remove jumper JMP 8 then
supply an external Ground to Pin 1.
