Notes
1. Alarm-1 = High signal (TTL, 5V/3.3V) if over/
under specified output limits.
2. Alarm-2 = High signal (TTL, 5V/3.3V) if over
95% of specified pump current limits.
3. Alarm-3 = High signal (TTL, 5V/3.3V) if over/
under specified pump temperature limits
25°C ±2°C.
4. Alarm-4 = High signal (TTL, 5V/3.3V) if over/
under specified optical input limits.
5. Alarm-5 = High signal (TTL, 5V/3.3V) if over/
under specified unit temperature limits 5°C
to 60°C.
6. The serial communication electrical signals
can be chosen by RS-232, 5V or 3.3V.
7. Do NOT connect reserved I/O-pins.
8. Input High signal (5V/3.3V) = The unit is
disabled (the laser is turned OFF).
9. Input High signal (5V/3.3V) = The laser
current is set to HALF specified maximum
current.
