Chapter 5 Operation Guide
（4）Pin 18 is the Master Oscillator (MO) signal. The MO should be
switched ON at least 5ms earlier than the Booster (BS) is switched ON.
Once the MO is switched ON, the laser starts to consume more electrical
power.
（5）Pin 19 is the Booster control input. HIGH means switching the BS
on and LOW means switching it OFF. The laser starts to emit light within
specified delay time after the pin 19 is set HIGH and stops emitting when
the pin 19 is set LOW.
（3）Pins 16 and 21 are the alarm and status outputs. These pins indicate
the following device states:
