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 genlock loss. (Any of these conditions may be suppressed
using the Alarm Suppress parameters.)
Incompatibility
Alarms
The FS1-X produces signal incompatibility alarms for a number of reasons. For example,
incompatible conversion alarms are possible when the FRC is not present or disabled (2
Channel operating mode). This is because in 2 Channel mode the FS1-X cannot convert
between frame rate families (59.94/29.97/23.98, or 50/25, or 24).
