Multiple movable barrier operator system and method
View Patent ↗A first moveable barrier operator is actuated to move a first moveable barrier and a light beam is encoded with operational information regarding the first movable barrier operator. The encoded light beam is transmitted from an emitter associated with the first moveable barrier operator to a first detector associated with the second moveable barrier operator. The second moveable barrier operator may be subsequently operated at least in part according to the operational information encoded in the light beam.
