you’re controlling when multiple units are operated from a single computer. The
ID LEDs on the front and rear panels perform the exact same function. No matter
which side of a rack you’re facing, you’ll be able to see one of the LEDs.
ALARM (red)
An alarm event has been detected. Press the STATUS button for information.
The Alarm LED may light because of a disconnected or failed power supply,
other hardware failure, video incompatibilities, or loss of reference. (Any of these
conditions may be suppressed using the Alarm Suppress parameters.)
Incompatibility Alarms
The FS3 produces signal incompatibility alarms for a number of reasons. For
example, incompatible conversion alarms can occur because the FS3 cannot
convert between frame rate families (59.94/29.97/23.98, or 50/25, or 24).
Example Alarms
Video incompatibilities that the FS3 may detect include the following examples:
