ABSTRACT:
A node device for a serial databus connecting a number of devices, having in each case three input and output units, in which case a second output unit of the node device can, in each case, be connected to a first input unit of a second node device of the databus. A third output unit of the node device can be connected to an input unit of a device, and a third input unit of the node device can be connected to an output unit of the device. The node device contains a multiplexer for connecting the first or third input unit to the second output unit of the node device and, furthermore, a detector, which is coupled to the first input unit, to the third input unit and to the multiplexer, for detection of an incoming data stream at the first and/or third input unit for appropriate control of the connection of the multiplexer.
