The custom circuit cards shown control a uni/bidirectional RF switch matrix. This circuit card has RS-485, RS-232, LCD, Keypad, Ethernet, bit shift port and one general I/O port. These cards are connected together so each can run the switch matrix, one being a remote controller, which may or may not be at the same location as the main controller.
