Abstract
The inventive data exchange device comprises a transmitter (SA4) fed by a power supply (VDDA), an electric cable (C1) whose first conducting wire is connected to a fixed potential point (GNDA) of the transmitter and second conducting wire is connected to a variable potential point of the transmitter and a receiver (SB4). Said receiver (SB4) comprises a component (DZB4) which defines a voltage threshold opposite to the direction of electric current in the cable (C1). Said device is embodied in such a way that it is simple and low-cost in the production thereof. The device makes it possible to interconnect a plurality of transmitters and receivers and is low sensitive with respect to voltage and parasite currents.
Claims8
An installation for exchanging information comprising a transmitter (SA3;
- SA4) supplied from a power supply (VDDA), an electric cable (C1) of which a first conductor is connected to a point of fixed potential (GNDA) of the transmitter and of which a second conductor is connected to a point of variable potential of the transmitter and at least one receiver (SB3;
- SB4), wherein the receiver or the receivers (SB3;
- SB4) comprise a component (P3;
- DZB4) defining a threshold voltage opposing the flow of the electric current through the cable (C1).
