6.2 GPI alarms
Only three alarms are present on the RJ45 connector as two pins are used for the AES/
RS422 data port and one pin is used for Frame delay pulse signal.
The three alarms are:
- Status error
- Video signal lost
- Black and burst lost
An active alarm condition means that the transistor is conducting.
