Abstract
In one aspect, a method is provided of effecting secure communications for a movable barrier operator and a trainable transmitter. The method includes, at the movable barrier operator, transmitting to a remote control a first radio frequency communication via a first communication protocol wherein the first radio frequency communication includes an access code. The method further includes receiving from the trainable transmitter a second radio frequency communication via a second communication protocol. The second radio frequency communication includes a derived access code based at least in part upon the access code. The method further includes learning the trainable transmitter in response to the derived access code corresponding to the access code.
