GPI Alarms menu
The GPO6 output is reserved for alarm indication and may have assigned any of the 38 video
and audio alarms.
Any number of alarms may be assigned to the GPI output; video missing and input groups
missing will assert an alarm immediately whereas the silence alarms can be assigned a delay
timer to delay the time after which an alarm is asserted. This ability is especially useful to
prevent false alarming during quiet periods in the audio.
Where more than one alarm is flagged and an alarm condition is asserted, use the various
status indicators to determine the exact cause.
Visual indication of GPO6 status is provided on the board edge.
See Section 2.3 for further discussion of GPIs and pinout details.
