Patent ID: 7088218

Claim:
A system for wirelessly activating an appliance, the appliance associated with an appliance receiver for receiving a wireless activation signal, the appliance responding to one of a plurality of transmission schemes, the system comprising: a receiver section separate from the appliance receiver, the receiver section operative to receive a radio frequency activation signal; a transmitter operative to transmit a radio frequency activation signal; at least one user activation input, each activation input identifying a wireless channel; memory holding data describing a plurality of rolling code transmission schemes associated with a rolling code mode and a plurality of fixed code transmission schemes, at least one fixed code transmission scheme associated with each of at least one fixed code mode; and control logic in communication with the receiver section, the transmitter, the at least one user activation input and the memory, for each channel the control logic maintaining a channel mode set initially to a rolling code mode, the channel mode changing to one of the at least one fixed code mode if the channel is trained to a fixed code in response to receiving a signal transmitted from an existing transmitter, the control logic in response to an assertion of the user activation input associated with the channel generating and transmitting an activation signal based on each transmission scheme associated with the mode maintained for the channel.
