Caution: Please check the control voltage level and ensure that the level is in
accordance with the requirements. Over voltage and voltage ripple may damage the
product.
The Service Security Interface is pin 2-3 and pin 1-4 of CTRL-INTERFACE.If the pin 2-3
and pin 1-4 are disconnected, the laser will immediately stop emitting light, and the laser Ready
signal output will change to low level. Be sure to short-circuit pin 2-3 and pin 1-4 before using
the laser. If it is not short-circuited, the laser will display InterLock alarm after power-on.
