Table 11 Pin DB15 Connection Details
4.2 Communication Interface
The communication interface is the DB9, which has 2 kinds of communications, Rs232 and CAN
respectively. The communication is mainly about the parameters relating to core components inside, only for
reference to connect to control system. If communication is not needed, there will be no connection and it
will not affect the normal working of the laser.
4.3 Functions Reequipment
4.3.1 PWM
The power will be adjusted by the duty cycle, and the frequency is from 1 to 100kHz (Please avoid the
frequency from 2-4kHz with noise.). The range of duty cycle is from 4% to 52%, and the current must be
within 10-15mA. Otherwise, it will be deformed due to insufficient current.
