1. Do not connect to reserved pins.
2. Normal = TTL low, alarm = TTL high if the output power falls 2 dB below the minimum value.
3. Normal = TTL low, alarm = TTL high if pump bias exceeds 95% of its end-of-life value.
4. Normal = TTL low, alarm = TTL high if pump temperature exceeds 35 °C.
5. The EDFA is equipped with an optical transient suppression feature when this pin is tied to GND. The EDFA will turn all pumps off, if the
input power is too low. Tying this pin to 5 V will disable this feature; however, damage to the optical connectors and components may occur if
the amplifier is turned on without the presence of an optical signal.
6. Normal = TTL low, alarm = TTL high if input power is less than 2 dB below minimum PIN.
7. Amplifier enable (all pumps are on) = TTL low, amplifier disable (all pumps are off) = TTL high.
