FIELD: radio engineering, communication.
SUBSTANCE: apparatus has at least two devices, a bus with a receiving line and a transmitting line linking said devices, and a bus control device connected to the bus. The bus control device has a first means of controlling transmission of data defined by a certain network as voltage data signals, over a transmitting line and a receiving line, and a second means of feeding the voltage data signals to the transmitting line with first voltage supply signals, adapted to supply voltage to devices of a first aircraft system, and a third means of feeding voltage data signals to the receiving line with second voltage supply signals, adapted to supply voltage to devices of a second aircraft system.
EFFECT: high efficiency.
