Resistance coupled data transmission arrangement

A data transmission arrangement powered by at least a supply voltage source (UB), includes a transmitter (11), a receiver (13) and a data transmission path (12) operated in the differential mode and terminated by its characteristic impedance. A reliable detection is possible even upon rupture of one of the two transmission wires (18, 21) by the use of a pure resistance network including the resistors (17, 20) of the transmitter (11), of the data transmission path (12) having the resistors (22, 23) and the resistors (28, 29, 30, 31) of the receiver (13), at least each time one matching resistor (24, 26) being provided on the receiver side connected each to a transmission wire (18, 21) of the data transmission path (12) for producing opposite levels (U3, U4) in the receiver (13) and for producing an absolute level in the case of disturbance of a transmission wire (18 or 21).
