GPIO Interface Setup
Follow the steps below to setup the applicator interface:
1. Know your system’s requirements for the input signal levels that will control the printer. Two
different circuit suggestions are as follows:
• Direct applicator interface:
This sample circuit uses the
printer’s +5 VDC and Ground
to supply the control devices
that interface to the GPIO
input signal lines.

• Isolated applicator interface:
This sample circuit uses an
external +5 VDC and Ground to
supply the control devices that
interface to the GPIO input
signal lines. To use this
configuration, remove JMP7
and JMP8 from the Applicator
Interface Card (see Step 6,
below).

2. Know your system’s requirements for the output signal levels that will control the applicator. The
output voltage of the printer’s signal lines (such as End of Print, Data Ready, and Service Required) is
selectable.
The table below details the hardware and operational functions of the GPIO Port. Note that all signal
directions are given relative to the printer.
