RAYLASE SP-ICE-1 PCI/e PRO Control Cards
2.4.4
Port C, Laser / I/O Interface
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 or a PLC.
FPS = first pulse suppression, 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.
Adaption of Outputs
FPS = first pulse suppression, LM = laser modulation, MIP = mark in progress
Analog Output
The analog output is dedicated to control the diode or lamp current of an Nd:YAG laser. The
output voltage range can be adjusted via software (commands Write_DA and Write_DA_List).
