<P>PROBLEM TO BE SOLVED: To provide an information transmission method and device in which a device can determine and automatically set information such as IP address based on position information and arrangement order that are detected. <P>SOLUTION: When new position information and information about arrangement order are needed, each data processing device transmits position confirmation data to a branch transmission line. The position confirmation data includes information designating a transmission direction to a main transmission line or the branch transmission line. When a relay device receives the position confirmation data, the relay device relays the position confirmation data to a predetermined direction. Each data processing device determines the position information and information about arrangement order of the own device and the like, based on the number, data content and the like of the position confirmation data received from the relay device. <P>COPYRIGHT: (C)2013,JPO&INPIT |
