Below is the DB25 control timing diagram:
 A--System Initialization: The laser can accept signal only after 12s switch on the laser
power.
 B--Pump charging time: Range (8ms-35ms), 8ms is recommended.
 C--Range: 1ms-8ms, 4ms is recommended.
 D--Frequency switching time: Range: 4-8ms, 8ms is recommended.
 E--Class II SIMMER This value is for controlling the height(power) of the first pulse
which can be adjusted via GUI (the supporting software of the laser).
 F--The height of the first pulse: This can be adjusted via GUI (the supporting software of
the laser).
Remarks: After provide 24V voltage, you need to wait 12s before use the laser.
① Fiber laser control system self-locking: If fiber laser received unusual warning signal
(Such as: higher temperature, the 24V power supply is too low)
work. Please restart the fiber laser if you need to recover the machine.
