Transmitter and method for transmitting an RF control signal
Abstract:
A transmitter for transmitting an RF control signal to a remote system includes a user input device, a memory and a transmitter circuit. The memory includes control data associated with the remote device. The control data includes a first frequency and a second frequency. The transmitter circuit is coupled to the user input device and memory. In response to a single user input, the transmitter circuit generates a rolling code signal, transmits the rolling code signal at the first frequency for a predetermined amount of time, and, upon expiration of the predetermined about of time, transmits the rolling code signal at the second frequency.
