The invention is based on a known door or window drive with a motor, controlled with the aid of a computer, and with a plurality of operator control units for controlling the drive from various remote positions. A disadvantage of this prior art is that the mechanical switches used as operator control units cannot be operated independently of one another. The aim of the invention is to simplify the control device of the drive and the operating of the control. This is achieved according to the invention by the operator control units being designed as electronic input units 6 which are connected in parallel and have a keypad (a-f), by means of which control signals in the form of control pulses can be input into the computer, the computer being controllable from any desired input unit 6 by means of the control signal last input in each case. <IMAGE> |
