4.2.2. Displaying the Output Video Standard
When the reclocker is enabled, the 7707VR-4 detects the Video standards of the signal present at its
outputs. To display the Video Standard press the pushbutton one or more times until the
VSD1, VSD2,
VSD3
or
VSD4
message is shown on the display. After one second the detected video standard will be
shown. For the sake of brevity, only
VSD1
will be discussed in the manual.

4.2.3. Video Output On Loss
The
Video Output on Loss
occurs when input video to the transmitter or the fiber input to the receiver is
lost. The 7707VR-4 will generate SD-SDI grey video based on the previous input standard under
continuous video mode. Alternatively the 7707VR-4 will mute the video outputs if discontinuous mode is
chosen. Each individual output can be configured for continuous or discontinuous mode independently.
To change the video output on loss, press the push button and cycle the toggle switch one or more times
until the
VOUT
message is shown on the display. Press the push button and cycle through the outputs:
OUT1, OUT2, OUT3, OUT4.
Press the push button when the desired output is selected and then cycle
through
CONT (
continuous mode) or
DISC (
discontinuous mode)
.
Press the push button when the
desired mode is shown on the display. For the sake of brevity, only
VSD1
will be discussed in the manual.
