A unique communications protocol used on the management ring allows multiple types of logical devices (also called ring devices) to communicate with one another along the ring. Each site controller authorizes terminals within a corresponding group of terminals to generate cash tickets and is capable of validating every cash ticket generated within the video lottery system. The site controllers emulate several logical devices including a cash ticket validation console, a terminal polling device and a ring issuing device. The site controllers and terminals communicate via encrypted messages for security purposes. This encryption system use…
