Abstract:
1. A system for wirelessly activating an appliance, the appliance responding to one of a plurality of transmission schemes, the system comprising: a transmitter operative to transmit a radio frequency activation signal based on any of the plurality of transmission schemes; at least one user activation input, each activation input identifying a wireless channel; a user programming input; memory holding data describing a plurality of rolling code transmission schemes and a plurality of fixed code transmission schemes; and control logic in communication with the transmitter, the at least one user activation input, the user programming input, and the memory, wherein the control logic implements a rolling code programming mode, a fixed code programming mode, and an operating mode; the control logic in rolling code programming mode generating and transmitting a sequence of rolling code activation signals, each rolling code activation signal in the sequence of rolling code activation signals based on a different one of the plurality of rolling code transmission schemes, until user input indicates a successful rolling code transmission scheme, wherein the control logic stores data specifying the successful rolling code transmission scheme associated with one of the at least one user activation input; the control logic in fixed code programming mode receiving a fixed code from the user programming input then generating and transmitting a sequence of fixed code activation signals, each fixed code activation signal in the sequence of fixed code activation signals based on one of the plurality of fixed code transmission schemes and each transmitting the received fixed code, until user input indicates a successful fixed code transmission scheme, wherein the control logic stores the fixed code and data specifying the successful fixed code transmission scheme associated with one of the at least one user activation input; the control logic in operating mode receiving an activation input, retrieving data associated with the received activation input, and transmitting an activation signal based on the retrieved data.
