<p>The control system includes a receiver (3) associated with a closing system (2) and provided with, a central processing unit (5) for controlling motor (6) operation and a decoding unit (8) designed to interpret the data transmitted by a transmitter (4) towards a coding unit (9). The transmitter (4) and the receiver (3) contain an EPROM (11, 10) in which is programmed a code (12, 12A) which is decomposed into at least two parts (13, 14; 13A, 14A) one of which (13; 13A) permits the identification of a transmitter (4) with respect to a receiver (3) and the other part (14; 14A) corresponding to the control key is encoded by the transmitter (4) according to a defined algorithm known by the decoding unit (8) of the receiver (3). The EPROM (10) of the receiver (3) is programmed to be able to recognise an initialisation procedure transmitted to the receiver (3), with the aid of appropriate control means (16) so as to put into phase the second part (14A) of the code (12A) corresponding to the receiver (3) and to that (14) of a transmitter (4) previously identified with respect to the first part (13; 13A) of the code (12; 12A).</p> |
