STATUS INDICATORS
The 7711HDC has 3 LED Status indicators on the main circuit board front card edge to show operational
status of the card at a glance. Figure 7-1 shows the location of the LEDs and card edge controls.
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 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.
GENLOCK
This Green LED will be ON when there is a signal present at the module genlock
input. This LED does not indicate that a correct signal appropriate for the current
video format is present.
