Abstract

A data communication system, particularly for motor vehicles, includes a bus system with transmission lines which connect terminal devices to a common node. A protective circuit is connected between the transmission lines and a reference potential such as ground. If the ground connection of one of the terminal devices becomes detached, this protective circuit allows communication among the remaining terminal devices. The protective circuit is simultaneously secured against destruction in case of a short circuit.
