Abstract
A communication protocol is employed between a movable barrier operator and an associated wall button using the traditional signaling wires connecting them. Implementing the communication protocol using the existing signaling wires also allows backward compatibility with the traditional push wall buttons that have a physical contact switch. In one embodiment, the communication protocol allows bi-directional communication between the moveable barrier operator and the wall button. The bi-directional embodiment of the protocol allows further communications, such as handshaking, signal confirmation and more advanced control between the wall unit and the barrier operator.
