Patent ID: 8537727

Claim:
Device forming a central controller (C) intended to be linked to a remote peripheral (P 1 -P N ) by way of an electrical power line (L) of an avionic system, comprising a power transmitter ( 1 ) and a low-pass filter (C C-BF ) arranged between the power transmitter and the electrical line, characterised in that it comprises means for transmitting/receiving data ( 3 ) in baseband and a high-pass filter (C C-HF ) arranged between the data transmission/reception means and the electrical line, the electrical line being of the kind mutualized for the transmission of power at low frequency from the central controller to the remote peripheral and for the simultaneous bidirectional transmission of data in baseband at high frequency between the central controller and the remote peripheral, the data transmission/reception means ( 3 , 4 ) comprising a differential amplifier ( 5 ) able to discriminate, among the data transiting on the electrical line, the data transmitted local (EM) from the data to be received (REC).
