Abstract
A barrier operator is configured to learn and receive disparate wireless transmission signals to control movement of a barrier. The operator includes a receiver core circuit adapted to receive wireless transmission signals containing known and unknown formatted data words. A microcontroller is adapted to determine a fixed code portion of the unknown formatted data words. The microcontroller is also associated with a memory unit and connected to the receiver core circuit for storing in the memory unit the known formatted data words and the unknown formatted data words if the fixed code portion can be determined when the microcontroller is in a learn mode. The receiver core circuit may also scan only frequencies associated with learn codes, pre-selected frequencies, and incremental frequencies within a predetermined range of frequencies.
