Card edge monitoring
The front edge of the card provides useful power rail monitoring and input status.
TANDEM 320 front edge view
See
Card Edge Controls
for explanation of card edge LEDs.
The card edge LEDs and 10-digit display may be used in conjunction with status information
from any connected remote status panel display or from VisionWeb if available.
Board edge control was removed from TANDEM 320 in 2018. Therefore the card edge control
information is only relevant for older versions of the product.
Basic fault finding guide
The Power OK LEDs are not illuminated
Check that the frame PSU is functioning – refer to the appropriate frame manual for detailed
information
There is no video output
Check that a valid SDI input is present and that any cabling is intact
The video output exhibits jitter
Check that the input SDI stability is within normal limits
The card no longer responds to card edge or front panel control
Check that the card is seated correctly and that the Power OK LEDs are lit
Check any active control panel cabling

If necessary reset the card
Resetting the card
If required, the card may be reset by removing the card from the rack and then re-inserting it
It is safe to re-insert the card whilst the rack is powered. Any previous configuration will be
retained, use a factory reset to erase any configurations stored in the card
