2.4.1 Laser Control Interface 1
The interface provides analogous signals to control laser power and digital signals to control
laser devices such as a laser modulation driver. Further digital signals can be used for syn-
chronizing marking with external controllers – for instance a foot switch.
FPS = first pulse suppression, hc = high current, LM = laser modulation, MIP = mark in progress
Please note:
/START_MARK and /STOP_MARK are read simultaneously with the laser interface
(
 page 13). After the input buffer, the signals will be merged with an OR function.
The LM signal can be inverted via a jumper (  page 14). The inversion of the signals FPS,
LM-GATE and MIP can be set via software.
Analog output
The analog output ANA_OUT1 is dedicated to control the diode or lamp current of a
Nd:YAG laser. The output voltage range can be adjusted via software.
