All Compix systems come with a fill (video) and key output. If your switcher has a DSK or keyer button on the switcher panel itself (located to the right of the T-bar), your switcher can work with Compix. You will need two available inputs or an external key and external key-fill input as well as a sync. Look in your switcher manual for "keyer" or "dsk" for more information.
There are two ways of connecting sync: connect the Compix system to your house Black Burst generator or set up frame sync for the input(s) the Compix system is going into. Without having sync set up, graphics will move continuously across the screen.
