The Power OK LED is not illuminated
Check that the frame PSU is functioning and ensure the ADDEC-310 is fully inserted into its slot.
Refer to the appropriate frame manual for detailed information.
The Freeze LED is illuminated
This LED will illuminate when the picture is set to frozen. This condition may have been set from a
remote control panel or Statesman PC controller. Un-set this condition or carry out a Defaults reset to
remove this condition.
There is no video output
Check that a valid analogue video input is present and that any cabling is intact.
The video output exhibits jitter
Check that the input video stability is within normal limits and that the maximum cable length has not
been exceeded.
Ensure that the external reference input is stable
The video output is not synchronous with other station sources
If the input analogue video is not synchronous with station sources, ensure that the ADDEC-310 is in
Synchronisation Mode and that an appropriate analogue composite video signal such as station Black
and Burst is used as a reference.
Check the video offset timing (delay) is correct for your application.
The card no longer responds to Statesman or front panel control
Check that the card is seated correctly and that the PSU LED is lit.
Check any active control panel cabling.
Check if the control panel can control another card in the same rack.
If necessary reset the card by simply removing the card from the rack and then re-inserting.
It is safe to re-insert the card whilst the rack is powered.
Re-setting the card
Use the Factory Default/Reset facility accessible from the board edge, active control panel or
Statesman PC control system.
