How to use peel-off Godex printer port like triger button from PLC - in this example it is RT730i Pro

In thsi case we will use black and white wires from peel off port.

You need fro getting good RTC with pee-off to send command: ^XSETRTC,APPLYCURRENT,1

After printer is power on and before send printjob those two wires need one time short to connect - look video.

In this way customer can for example recall label from LCD or also remotly via LAN but

 PLC will control when some label need to be printed.This is using when printer does not have GPIO - applicator port.
