An apparatus for identifying a parameter of a movable barrier.

摘要

An apparatus for identifying a parameter of a movable barrier operator comprises a rotatable member; a mechanism for coupling the rotatable member to a motive mechanism (11) such that movement of the motive mechanism results in a corresponding movement of the rotatable member; and a plurality of aspects (23) connected to the rotatable member and being configured to provide data corresponding to a parameter of the movable barrier operator such that the parameter may thereby be identified.
