Patent ID: 7931068

Claim:
A shade control system comprising: a plurality of drive units each having a motor adapted for moving an associated shade member; a plurality of drive unit controllers each capable of generating command signals for directing at least one of the drive units to move its associated shade member; and a single two-way communication bus capable of transmitting the command signals, each of the drive units and drive unit controllers connected to the single two-way communication bus without any intervening devices such that each drive unit controller is adapted to be assignable to communicate with any of the drive units, and each of the drive units is assignable to communicate with any of the drive unit controllers; wherein during configuration of the system at least one of the drive unit controllers is operable to select one of the drive units to be assigned to the drive unit controller such that in response to being selected the selected drive unit automatically cycles its associated shade member by raising and lowering the shade member over a short distance to provide visual indication of the selected drive unit, and wherein the at least one drive unit controller is then operable to assign the selected drive unit to the drive unit controller.
