An addressing device has an address generator (43) and an address line (2) connected to it. In addition, there are at least one data line (1) and at least one supply line (3), which together form a cable (1, 2, 3). This cable (1, 2, 3) interconnects a multiplicity of switching positions (14) containing switching steps (13) connected to a data line (1). In addition, each switching position (14) contains an address detector (12) operated via the switching steps (8, 13). The addresss generator (43) supplies only one standard signal which is altered via an impedance component (7) together with the length of the cable in accordance with a parameter so that, after the first switching step (8) has switched and the data have been exchanged, the switching position of the next line can be selected via a second switching step with the same standard signal. |
