Abstract:
1. A method for operating a remote control system, the method comprising the steps of: transmitting a signal from a remote control device having a unique code, the signal selected from the group consisting of an initiation signal, a signal comprising said unique code, and combinations thereof; receiving the signal by a remotely-controlled device in communication with the remote control device, the remotely-controlled device having a unique address and being configured to selectively react to the signal by sending said unique address to the remote control device to receive the signal comprising said unique code from the remote control device and store said unique code in a code storage in case said signal is an initiation signal and said code storage is void of a code, and to await a command signal from the remote control device in case said code storage contains a code; transmitting a command signal from the remote control device to the reactive remotely-controlled device, said command signal comprising the unique address; selectively transmitting an authorization request signal from the reactive remotely-controlled device responsive to the command signal of the remote control device; transmitting a response signal from the remote control device in response to the authorization request signal of the remotely-controlled device, said response signal being generated using said unique code; and verifying the response signal from the remote control device by the remotely-controlled device to drive a controllable unit by the remotely-controlled device, said response signal being verified by generating a further coded signal using said unique code and by carrying out a comparative procedure of the response signal and said further coded signal.
