Start of Print
(SOP)
Programmable Input
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.
5
End of Print
(EOP)
Programmable Output
Signifies the end of the print process. Can be monitored to
initiate next Start of Print sequence. Minimum signal time
30ms.
6 & 8 Signal Ground Ground N/A Ground
7 +24 VDC 1.6 Amp (fused) Output P24 VDC

The operation of this multi-function port is configuration dependent. For GPIO operation, disable all optional functions not used (i.e., Present
Sensor and Cutter) and set GPIO to “YES” (or on display-equipped models set GPIO Device to “APPLICATOR”). Use the Configuration Set
command (<STX>Kc), or program the selections on non-display models via the “Printer Setup Menu List” or on display-equipped models via the
“Menu System.”
M-Class Sample SOP Circuit
Pin 3 should be pulled to +5VDC. In additional, connections
for the external Start of Print control can either be directly made
to Pin 4 of the Option Port (or Main PCB connector) using a
TTL-level input, or via an interface circuit (similar to the one
shown). For more information, see the table below.
