LED 1, VIDEO STATUS:
signal is detected the LED will be green. When CRC errors are detected within the input video
signal (with error detection enabled, see section 4.2.17) the LED will flash red. If no video is
detected on the video input of the 7707MT-HD the LED will remain off.
LED 2, LINK STATUS:
signal is detected the LED will be green. When CRC errors are detected within the input video
signal (with error detection enabled, see section 4.2.16) the LED will flash red. If no valid
optical signal is detected on the fiber input of the 7707MT-HD the LED will remain off. Note that
while the optical input to the companion 7707MR-HD is invalid (eg. not connected) then the
optical output of the companion 7707MR-HD will also be invalid. This will result in a
LINK...LOS condition (section 4.2.1) at the optical input of the 7707MT-HD.
LED 3, AUDIO 1 STATUS:
signal is detected the LED will be green. When errors are detected within the input audio
signal (with error detection enabled, see section 4.2.18) the LED will flash red. If no audio is
detected on the first audio input of the 7707MT-HD the LED will remain off.
LED 4, AUDIO 2 STATUS:
signal is detected the LED will be green. When errors are detected within the input audio
signal (with error detection enabled, see section 4.2.18) the LED will flash red. If no audio is
detected on the second audio input of the 7707MT-HD the LED will remain off.
LED 5, AUDIO 3 STATUS:
signal is detected the LED will be green. When errors are detected within the input audio
signal (with error detection enabled, see section 4.2.18) the LED will flash red. If no audio is
detected on the third audio input of the 7707MT-HD the LED will remain off.
LED 6, AUDIO 4 STATUS:
signal is detected the LED will be green. When errors are detected within the input audio
signal (with error detection enabled, see section 4.2.18) the LED will flash red. If no audio is
detected on the fourth audio input of the 7707MT-HD the LED will remain off.
LED 7, SERIAL IN STATUS: This LED indicates the status of Serial input data. When a valid input data
signal is detected the LED will be green. When parity errors are detected (with error detection
enabled, and parity information present) the LED will flash red. If no data is detected on the
serial data input of the 7707MT-HD the LED will remain off.
LED 9 SERIAL OUT STATUS: This LED indicates the status of Serial output data. When a valid output
data signal is detected the LED will be green. If no output serial data is detected the LED will
remain off.

DOT MATRIX DISPLAY
Additional signal and status monitoring is provided via the 4-digit dot-matrix display 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.
The most recent user selection will be maintained in non-volatile memory in the event of power
loss to the module.
