This fix corrects the need to have a valid SDI signal entering Input 1 of the Quad SDI Capture Card in order maintain the cards other inputs. Symptoms of this problem include needing an SDI source present at Input 1 for other Inputs to be displayed or inputs losing sync when Input 1 source is removed and timing problems showing on the top quarter of the display. This fix only works in conjunction with the v7.14.2 Vision driver software from Datapath.
