ABSTRACT:
A method and an apparatus for automatically sensing and configuring a termination in a network bus configuration are provided by input logic signals indicating whether or not a device connected to the network bus is located at an end position. If the device is at an end position, the network is automatically terminated by a matched load impedance located in the device. Because the load resistance at the ends of the network match the impedance of the communication medium, data loss due to signal reflections is eliminated.
