Patent ID: 7057494

Claim:
A method for automatically learning a rolling type access code from a learning transmitter by a barrier movement operator, comprising steps of: receiving by the barrier movement operator a first rolling type access code from a first transmitter, the first rolling access code having a fixed identification portion recognized by the operator; beginning a learn mode operation in response to receipt of the first rolling access code by the barrier movement operator; saving a representation of the first rolling type access code received from the first transmitter in the barrier movement operator; receiving the first rolling type access code from the first transmitter by the learning transmitter, and storing a representation of the first rolling type access code therein; receiving, by the operator, a second rolling type access code from the learning transmitter within a predetermined period of time after from receiving the first rolling type access code; comparing the second rolling type access code with the first rolling type access code saved in the operator; storing the representation of the second rolling type access code in the operator when the comparing step identifies that a predetermined relationship exists between the first rolling type access code and the second rolling type access code.
