The system has a master (2) including a master transmission stage (25) i.e. tension signal transmitter, for transmission of signal corresponding to an actual switching condition of a lighting device. A master receiving stage (26) i.e. current signal receiver, receives signals of a branch. A slave (8) has a slave receiving stage (28) i.e. voltage signal receiver, for receiving the signals corresponding to the switching condition of the device. A slave-transmission stage (27) i.e. current signal transmitter, transmits the signals to a controller of the master. An independent claim is also included for a method for operating a master and slave system. |
