Abstract:
1. A system for wirelessly activating an appliance, the appliance responding to an activation signal based on one of a plurality of different transmission schemes, the system comprising: a radio frequency transmitter operative to transmit activation signals; at least one user activation input, each activation input identifying a channel; a programming input; memory holding data describing a plurality of different rolling code transmission schemes associated with a rolling code mode and a plurality of different fixed code transmission schemes associated with a fixed code mode; and control logic in communication with the transmitter, the at least one user activation input, the programming 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 the fixed code mode if the channel is trained to a fixed code received from the programming input, the control logic, in response to an assertion of the user activation input associated with the channel, generating a sequence of different activation signals for the transmitter to transmit, wherein each activation signal is based on a respective one of the transmission schemes associated with the mode maintained for the channel; wherein each activation signal that is based on a respective one of the fixed code transmission schemes includes the fixed code; wherein for each activation signal that is based on a respective one of the fixed code transmission schemes, the control logic generating a second activation signal based on the same respective one of the fixed code transmission schemes for the transmitter to transmit, wherein each second activation signal includes a reversal of the fixed code.
