5.2 GPI alarms
Only three alarms are present on the 8P8C Jack connector as four of the pins are used for
the RS422 data port.
The three alarms are:

Power present (negative logic)

Video signal lost

Laser failure
An active alarm condition means that the transistor is conducting.
The power present alarm should always be active during normal operation.
