GPIO Port Description

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”.

GPIO Port Connections

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:

GPIO Pin Functions

Pin	Signal	Signal	Signal	Description
#	Name	State	Direction*
1	Vcc	+5 VDC	Output	Printer +5 VDC
2	Ribbon	Low	Output	Goes low when the printer
	Fault			detects a ribbon fault.
3	Paper	Low	Output	Goes low when the printer
	Fault			detects a label movement fault.
4	Printer	Low	Output	Goes low when any printer fault
	Fault			is detected.
5	Spare	Reserved	Output	N/A
6	End of Print	Programmable	Output	Programmable
7	Spare	Reserved	Input	N/A
8	Start of	Low	Input	When ready to print a label, the
	Print Signal			Applicator should set this signal
				low for at least 50ms or until the
				End of Print signal goes not
				active.
9	Signal	Ground	N/A	N/A
	Ground
*Signal direction is given relative to the printer.
