CUSTOMER CONNECTOR:
This is the connector for controlling Laser Marker by external signals.
In some applications it is necessary to control the Laser Marker externally. It shall be able to detect alarms,
externally select the message number to be printed, start the marking or stop the laser automatically in
case of an error in the production line.
The Laser Marker can automatically perform all these functions, among others, without operator
interventions. The signals are alarm output, print complete output, message selection input, etc. The pin
assignment is as follows:
