Abstract
A barrier movement operator system having a receiver for receiving, learning and responding to transmitted rolling code type access codes; at least one trained transmitter for operating the system by transmitting a rolling code type access code to the receiver; at least one learning transmitter for learning the rolling code type access code from said trained transmitter in order to operate the system; a controller for evaluating the relationship between the learning transmitter rolling type access code and the trained transmitter rolling type access code; and a device for providing a barrier movement in response to access codes received by the receiver. The barrier movement operator provides a method of learning valid security codes by a security code receiver comprising the steps of receiving a first security code, then within a predetermined period of time receiving a second security code, having a predetermined relationship to the first security code; and storing a representation of the second security code as a valid security code.
