<P>PROBLEM TO BE SOLVED: To provide a communication system, in which a plurality of communication devices are connected through a ring-shaped differential serial transmission path, capable of reducing power consumption of a communication device not involved in data transfer and capable of reducing latency in relaying the plurality of communication devices. <P>SOLUTION: The present invention includes bypass control means that selectively outputs serial bypass data in which serial reception data is bypassed before conversion of serial reception data into a reception packet and serial transmission data to a differential serial transmission path, and transfers a communication device not involved in data transfer to a bypass mode for bypass output at a stage of serial data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
