GENERAL LEDS
Three large LEDS on the front of the main board indicate the general health of the module.
LOCAL FAULT:
This Red LED indicates poor module health and will be ON during the absence of a
valid input signal, an invalid reference, or if a local input power fault exists (i.e.: a
blown fuse). The LOCAL FAULT indication can also be reported to the frame
through the FRAME STATUS jumper.
MODULE OK:
This Green LED indicates good module health. It will be ON when a valid input
signal is present, and the board power is good.
VIDEO PRESENT:
This Green LED will be ON when there is a valid video signal present at the module
input.
