Patent ID: 8417358

Claim:
A system comprising: a station including a memory and a processor; and a controller configured to transmit to the station a controller identification code and a controller key code; wherein, in a binding mode entered in response to a bind command from the controller, said processor is configured to: save the controller identification code and the controller key code in the memory in a table form; and prevent the station from responding to messages from other controllers attempting to place the station in the binding mode, unless the controller also transmits the bind command to enter a new registration; and wherein, in a normal mode, said processor is configured to: verify presence of the controller identification code and the controller key code in the memory; disable the processor if the controller identification code and the controller key code are not present in the memory; enable the processor if the controller identification code and the controller key code are present in the memory; and prevent the station from transferring a station identification code to the controller after determining that the controller identification code received from the controller does not correspond to a code stored in memory.
