For the sake ofcomparison, pressing a card edge button or DCP-111 Control Panel button acts thesame as the card receiving a GPI edge trigger. All of the GPI functions listed abovecan be triggered using GPI edge triggers.NoteEdge triggered GPI signals should be stable at the selected levelfor 1 full frame of video to ensure the action will be triggered.GPI Level TriggersLevel triggers are used when you want to assert a particular state for a setting. In thiscase, the user defines the on air state of the function as being either LEVEL HIGH orLEVEL LOW.
