NOTE:
①
Ext_Red_EN: laser emits red light when this signal is high;red light
shuts down automatically when laser emits;
②
EXT_ON/OFF: switch on/off power unit inside laser;
③
Ext_Red_Always: use with Ext_Red_EN signal, red light keeps on when
these two signals are high;
④
use relay to provide normal close point and normal open point of laser
emit signal and alarm signal.
