Note:
1. Raycus new lasers need to use 24VPWM signal control, while the old ones use 5V
PWM signal. And new lasers can use the serial port control only before the key switch is in
the REM state, while key switch of the old ones is in the ON state. It will indicate whether
the laser is 24V PWM interface control or not; when it’s not indicated or marked with 5V,
5V control mode can be applied totally.
2. PWM select 5V control (Dip switch: 1 pin is OFF, 2 pin is ONOptionally select
one among 3 pin and 4 pin is ON, then another one is OFF.)
3. PWM of Max laser select 24V control (Dip switch: 1 pin is ON, 2 pin is OFF
Optionally select one among 3 pin and 4 pin is ON, then another one is OFF.)
