PURPOSE:To perform normal transmission, even if a transmission line is broken, by connecting a master station and slave stations with a duplex loop and outputting data bidirectionally at the slave stations, in a multiple signal transmission system used in a car, for the data communication betwen the master and slave stations. CONSTITUTION:A master station 1 transmits a control code which invites the transmission of slave stations at a prescribed period. Slave stations 2, 3 receive the control code of the master station, and when the code is a code inviting the transmission of a slave station, data are transmitted following the control code. Since multiple signal transmission lines 4-9 form bidirectional loop, the slave station outputs the data on both output lines and transmits the data to the master station. |
