A barrier movement operator system having a receiver for receiving (80), learning and responding to transmitted rolling code type access codes; at least one trained transmitter (30) for operation the system by transmitting a rolling code type access code to the receiver; at least one learning transmitter (31) for learning the rolling code type access code from said trained transmitter in order to operate the system; a controller (70) 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. |
