ABSTRACT:
The primary interface (2) is connected to all secondary interfaces (3) by a single two-wire line (2) carrying an alternating supply current under low voltage, and control and test data in the form of pulses; each secondary interface (3) is connected to all its labels (4) by a single two-wire line (34) carrying an alternating supply current under very low voltage, and control and test data in the form of pulses; all data are transmitted using the carrier current principle.
