PIN	SIGNAL	SIGNAL
#	NAME	TYPE	FUNCTIONAL DESCRIPTION
5	PAUSE	Input	To toggle the current PAUSE state, this input must be
			asserted LOW for 200 milliseconds, or until the SERVICE
			REQUIRED output (pin 10) changes state.
6	REPRINT	Input	If the REPRINT feature is enabled – this input must be
			asserted LOW to cause the printer to reprint the last label.
			(See the Configuration and Calibration section.)
			If the REPRINT feature is disabled – this Input is ignored.
7	+28V	Power	Interface Power Supply – supplies power to external
	(Fused at		sensors as required.
	1.5A)
8	POWER	Ground	Interface Power Ground.
	GROUND
	(+28V Return)
9	RIBBON	Output	If the RIBBON LOW feature is enabled, and the amount of
	LOW		ribbon remaining on the supply spool is below a specific
			threshold level – this output will be asserted HIGH.
			If the RIBBON LOW feature is disabled – this output lead is
			disabled. (See the Configuration and Calibration section.)
10	SERVICE	Output	While either the media cover is open, the printhead is open, the
	REQUIRED		ribbon is out, the media is out, the printer is paused, or an
			operational fault has occurred, this output will be asserted LOW..
			If the applicator RESYNCH mode is set to ERROR mode,
			this signal will also assert LOW for a RESYNCH error.
11	END PRINT	Output	MODE 0: The Applicator Port is OFF.
			MODE 1: Asserted LOW only while the printer is moving
			the label forward; otherwise deasserted HIGH
			MODE 2: Asserted HIGH only while the printer is moving
			the label forward; otherwise deasserted LOW.
			MODE 3: (Default) Asserted LOW for 20 milliseconds when
			a label has been completed and positioned. Not asserted
			during continuous printing.
			MODE 4: Asserted HIGH for 20 milliseconds when a label
			has been completed and positioned. Not asserted during
			continuous printing.
12	MEDIA OUT	Output	Asserted LOW while there is no media in the printer.
13	RIBBON OUT	Output	Asserted LOW while there is no ribbon in the printer.
14	DATA	Output	Asserted LOW when sufficient data has been received to
	READY		begin printing the next label.
			De-asserted HIGH whenever printing stops after the current
			label, due to either a PAUSE condition or the absence of a
			label format.
15	SPARE	Output	To Be Determined
