Abstract: A card-cage audio visual signal control system with card ID assignment is disclosed. Cards are removably installed in slots inside a cage enclosure, each card performing a specific function with respect to audio visual signals applied to the card. Card IDs are used to communicate with the cards. Card IDs alternate between physical and logical addresses for each card, thus allowing the cards to be moved from slot to slot inside the cage enclosure without having to reprogram the card-cage audio visual signal control system every time a card is so moved.
