PA、MO、Red indicator light: Monitor the control signal. Green light means signal is effective
(high level), and red light means signal is not effective (low level).
D0-D7 indicator light：Monitor the current power signal of the laser, corresponding the 8-bit
binary mode, D0 is the lowest and D7 is the highest. Green light means this pin signal is effective
(high level), and red light means this pin signal is not effective (low level).
PRR/kHz and PULSE/ns: Monitor the actual laser working frequency and pulse width.
Pump temperature: Monitor the temperature of optical module.
Power current: Monitor the post amplifier driving current value of the laser.
System parameter: Internal system parameter setting interface (For JPT internal use only).
Log record: To record the laser setting and alarm.
Alarm record: To record the sequence of the latest 10 laser alarms.
2) Alarm description
Board tempLT: Board temperature is lower than the set temperature.
Board tempOT: Board temperature is higher than the set temperature.
Pump tempLT: Pump temperature is lower than the set temperature.
Pump tempOT: Pump temperature is higher than the set temperature.
PRE lowE: Pre amplifier low current alarm.
Voltage error: Supplying voltage is too low or too high.
No pulseE: No seed source backlight signal detected or backlight signal frequency less than 1kHz.
Seed TEC: Seed source temperature is abnormal.
