STATUS INDICATOR LEDS
Two large LEDs on the front of the 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 on all 3 inputs, if any input detects a weak optical carrier, 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 on at least one of the input channels and board power is good.
There are three small LEDs that indicate the status for each channel.
PRESENT:
This Green LED indicates the presence of a valid input video signal.
