LEDs and Module Indicators
General Information
The NEO composite video decoders have nine card-edge LEDs and
four standard module indicators.
All five decoder modules generate visible alarm signals to alert users of
failures or impending failures within the module. These alarm signals
can be found in the following locations:
•
As red or yellow LEDs on the front module card-edge
• As red or yellow LEDs on the 3901AIC Alarm Interconnect
Module or the 3901RES-E Resource Module (visible via light pipes
through the frame’s front panel)
• As part of a list of activated alarms found in the Setup menu
• In external systems connected to the alarm contact closures at the
back of the NEO frames
• On a PC screen where Pilot or another GUI-based control
application is being used
