System for processing multiple signal frequencies and data formats for a barrier operator
First Claim
1. A method for learning a wireless transmitter to a barrier operator, the method comprising:
- receiving a command signal that includes at least two redundant function code data words from a wireless transmitter by a receiver maintained by the operator;
determining a data format of said function code data words by a microcontroller connected to said receiver;
comparing each of said function code data words if said function code data format cannot be determined at said determining step; and
identifying a fixed code portion maintained by each of said transmitted function code data words based on said comparison step.

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.

11. A method of processing received command signals transmitted from a wireless transmitter to a barrier operator so as to actuate an access barrier, the method comprising:
-
placing a receiver into a command signal frequency scanning mode; receiving at said receiver a command signal which includes a function code data word associated with a function to be performed by the barrier operator; determining whether a data format of said function code data word is stored in said barrier operator; determining whether any portion of said function code data word matches one or more fixed code tags if said data format of said function code data word is not stored at said barrier operator; and carrying out the function associated with said function code data word at the barrier operator if a match is made at said second determining step. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
