The 8712 card can be Genlocked to a standard “black
and burst” or Tri-level sync signal applied to the
Genlock input on the back panel. The frame rate of
the “black and burst” signal must be the same as the
frame rate of the video output. The “Genlock
Reference,” under the button, must be set to the
type of Genlock signal being used as well. If the
Genlock input source is lost, the red Error LED will
illuminate, a Decoder Error will show, and the Error
list will show the error. The video will restore but will
not be Genlocked until the Genlock signal is restored.
