Abstract
Currently, in transformationally coupled linear data bus systems having separate transmission and reception lines, two transformers are used in order to achieve electrical isolation of data bus and terminal. According to one exemplary embodiment of the present invention, a data bus system is specified in which the terminal is connected via a directional coupler to the data bus lines in order to transmit and receive data via the data bus.
