STATUS INDICATOR LEDS
Two large LEDs at the front card-edge indicate operational health of the module as follows:
MODULE OK:
This green LED indicates good module health. It will be on while a valid optical
signal is present at the optical input and the card power is good.
LOCAL FAULT:
This red LED indicates poor module health. Two conditions could cause this fault
indication to be active. No valid signal is present at the optical input or if a card
power fault exists (i.e. a blown fuse). The LOCAL FAULT indication can also be
reported to the frame by setting the FRAME STATUS jumper.
There are five small LEDs on the back of the card-edge that indicate signal presence. These LEDs are Bi-
colour, and they are able to illuminate as red or green. The functions of these LEDs are as follows:
LED 1, VIDEO STATUS:
This LED indicates the status of the optical input video signal. When a valid
input video signal is detected the LED will be green. The LED will be red while
errors are detected within the input video. If no video is detected on the optical
input of the 7707VAR-HD the LED will remain off.
LED 2, AES 1 STATUS:
This LED indicates the status of Audio output 1. When a valid audio signal is
present at the output the LED will be green. If no audio is present at the first audio
output of the 7707VAR-HD the LED will remain off.
LED 3, AES 2 STATUS:
This LED indicates the status of Audio output 2. When a valid audio signal is
present at the output the LED will be green. If no audio is present at the second
audio output of the 7707VAR-HD the LED will remain off.
LED 4, AES 3 STATUS:
This LED indicates the status of Audio output 3. When a valid audio signal is
present at the output the LED will be green. If no audio is present at the third audio
output of the 7707VAR-HD the LED will remain off.
LED 5, AES 4 STATUS:
This LED indicates the status of Audio output 4. When a valid audio signal is
present at the output the LED will be green. If no audio is present at the fourth
audio output of the 7707VAR-HD the LED will remain off.

DOT-MATRIX DISPLAY AND CONTROLS
Additional monitoring and control functions are implemented via the 4-digit dot-matrix display and controls
located at the card-edge. The card-edge pushbutton and toggle-switch are used to navigate through the
display menu. Figure 4-2 provides a quick reference to the display menu structure.
Pressing the pushbutton advances the display to the next menu level. The toggle-switch may then be used
to move up or down through selections of that menu level. Select
BACK
to return to the previous menu
level.
If a specific menu selection has a configuration value associated with it, then this may be changed using
the toggle switch. Pressing the pushbutton will apply the displayed value and return the user to the
previous menu level.
