ABSTRACT:
An addressing device has a supply wire (1), an addressing wire (9), an information wire (2) and a reference wire (3) that connect to a multitude of addressable units (28). The address wire is connected to voltage references (16) of low output impedance (17). If a current signal is drawn through the address wire (9), the current originates from the addressable unit that is located next to the control unit (26) that has not yet been addressed. The current signal is used to address the unit. Once this addressing cycle is accomplished, the addressable unit (28) disconnects, and the following addressing action is received by the next addressable unit.
