Abstract:
A digital data exchange device for the dynamically electrical connection of a plurality of input ports to a plurality of output ports, comprising:a first multiplexer connected to the plurality of input ports, for selecting an output port thereof, thereby outputting data of said input port, wherein the data of the input port contains an output port ID; a demultiplexer, connected to the first multiplexer and the plurality of output ports, for selecting the output port based on the selected output port ID, thereby outputting the input port ID to the output port; and an address generator connected to the first multiplexer and demultiplexer, for generating input port IDs for the plurality of input ports in sequence, so that the first multiplexer selects the input port, and then the input port ID is outputted to the selected output port based on the output port ID by use of the demultiplexer, thereby connecting the input port to the output port.
