Port operation is configuration dependent: Disable all unused optional functions (e.g., Present Sensor
or Cutter) and set GPIO to "YES" (or on display-equipped models, to APPLICATOR). Use the
Configuration Set command (<STX>Kc); or program the selections for non-display models via the
"Printer Setup Menu List" and for display-equipped models via the menu.
The GPIO signals can be accessed via the front Option Port connector (Molex, P/N 44300-
800), or via the Main PCB J6 connector (AMP, P/N 640456-8), where the pin-outs (as
viewed when facing the printer) are as follows:

Description
Printer: Max +5 VDC, 100mA
Goes low upon printer detection of a fault
condition. Max +5 VDC, 100mA
Must be pulled high with 1k Ohm resistor
(see sample SOP circuit, below).
When active, will begin print. Recommend
only setting this signal to ACTIVE LOW.
When ready to print a label, the applicator
should hold this signal low for at least 50ms
– or until EOP goes not active. See sample
SOP circuit, below. Max +3.27 VDC, +/-
5mA
Signifies the end of the print process. Can
be monitored to initiate next Start of Print
sequence. Minimum signal time 30ms. Max
+5 VDC, 100mA
Ground
Printer: Max +24 VDC, 500mA
