AJA FS1 - Manual (Page 20)

Proc Amp—Shows that the ProcAmp values are different from the factory nominal
values. If lit, the video passing through the FS1 is being altered according to
changes in ProcAmp parameter settings (it’s no longer at unity).
LAN—This LED will flash once whenever the FS1 is being controlled by a Web
Browser input or remote panel. Web Browser actions that do not affect the
internal state of the FS1 will not cause the LED to blink.
Ref—Shows that the FS1 has an external reference video source applied to the Ref
connector.
Power and Status Indicators
Power 1—Shows that the FS1 #1 power supply is connected to AC mains power via
its power cord and is operational. Both the Power 1 and Power 2 LEDs must be
lit to ensure redundant power is available.
Power 2—Shows that the FS1 #2 power supply is connected to AC mains power via
its power cord and is operational.
Identify and ID—These two LEDs (one on the front panel and one on the rear) will
blink when directed to do so via the FS1’s Web browser interface “Identify”
button. This action is useful for identifying which FS1 you’re controlling when
there are multiple FS1 units in a machine room being controlled by a laptop or
computer. To do so via the browser, simply click “Identify” and then watch for
one of the FS1s “Identify” LEDs to blink. The “Identify” LED on the front
panel and “ID” LED on the rear panel 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—If This LED is illuminated, press the Status button to see a description of
the alarm event detected.
The Alarm LED may be lit because of a hardware failure, because of video
incompatibilities, or because of genlock loss. (Any of these conditions may be
filtered out using the Alarm Filters parameters.)
Note: only having one power cord connected to the FS1 will cause the alarm LED
to light—this may be filtered with the Alarm Filters parameters.
Video incompatibilities may be deduced from the “Alarm Status” screen. When the
Alarm LED is lit, press the front panel Status button to go directly to the “Alarm
Status” screen.
Video incompatibilities that the FS1 may detect include:
Video Incompatibility Detected Alarm Status screen will show
6.1 Genlock Source is set to “Reference”, but
Reference signal format is not compatible with
selected Output Format. Alarm Status screen shows:
“IN..... GEN Ref “
“OUT.... REF Incompat”
6.1 Genlock Source is set to “Reference”, and
selected Output Format is compatible with detected
Reference format, but Input signal format is not
compatible with detected Reference format. Example: if Reference and Output
formats are 525, but Input is 625,
Alarm Status screen shows:
“IN Incompat GEN Ref “
“OUT 525i 59 REF 525i 59 “
