 With the optional GPIO PCB, the printer can easily be programmed to interface
with most applicator devices. The GPIO functions are enabled and configured
using the menu system of the printer (see Section 4.1.4).  These parameters are
stored in non-volatile memory and saved for subsequent power-ups.

 When the GPIO is enabled, the printer will not print a label unless the Start of
Print signal is active. When a label is ready to print and the printer is waiting for
the Start of Print signal the printer will display “WAITING FOR SIGNAL”.

 

 

The GPIO Port interface connector (see next page) is a 9-pin Mini-DIN female
type (e.g., Kycon KMDG-9S-BS) requiring a 9-pin Mini-DIN plug (e.g., Kycon
KMDA-9P). Each GPIO pin function is detailed in the table below:
