Abstract: Networks on board of vehicles have to provide a rapid data throughput, and be still inexpensive and electromagnetically compatible (EMC). An interface (100, 110) comprising at least one physical layer and a method for transmitting at least one bit to at least one two-wire bus (10, 12), in particular to at least one C[ontroller]A[rea]N[etwork] bus, for example based on the ISO 11898 standard, are disclosed. It is proposed that the transmission takes place on the basis of the L[ocal]I[nterconnect]N[etwork] protocol. The same technology can be implanted in a device or a circuit arrangement.

Abstract: In a circuit arrangement for error recognition of a two-wire data bus through which transmitted, dominant bits are differentially transmitted on the two bus lines, it is proposed that the arrangement comprises means (4) for measuring the differential current, by means of which the difference of the drive currents with which the two bus lines are driven is measured in a transmitter when transmitting dominant bits on the data bus, and in that evaluation means (5) are provided which supply an error signal when the difference between the drive currents exceeds a predetermined limit value.
