Abstract

A door operator and related methodologies for learning new transmitter codes include a motor for moving the moveable barrier between two travel limit positions, an operator for controlling operations of the motor and a remote transmitter. The operator includes temporary and permanent memory devices to assist in learning new transmitter codes as needed. In one embodiment, the operator learns a new transmitter code by receiving signals from the remote transmitter after a storage button is depressed. In another embodiment, the operator learns a new transmitter code by periodically alternating between receipt of low range and high range radio frequency signals. In a similar embodiment, actuation of a transmitter button emits an infrared signal for programming the operator and a radio frequency signal for enabling the motor. In yet another embodiment, the transmitter is electrically connected to a port connector that is directly connected to the operator and whereupon actuation of the transmitter transfers the coded signals directly to a controller for learning thereof. Alternatively, insertion of the transmitter into the port may force the controller to generate and send a code to the transmitter. Accordingly, when the transmitter is removed from the port, actuation of a button causes the operator to initiate the appropriate function. In another embodiment, insertion of an indicia-carrying key into the operator could be used to program the operator. Or, actuating the buttons on the transmitter in a predetermined sequence could be used to program the transmitter with the controller.
