Abstract

PURPOSE:To transmit data through the master station between arbitrary stations, by receiving the transmission request signal from a slave station to transmit the designation signal for transmission station to this slave station and by designating the master station itself as the receiving station. CONSTITUTION:Slave station 2 transmits the transmission request signal to master station 1. The master station transmits the designation signal for transmission station to this slave station and designates the master station itself as the receiving station. When master station 1 transmits the transmission start signal to slave station 2, slave station 2 transmits the designation desired number for receiving station through master station 1 to slave stations 2' and 2''. Master station 1 transmits this designation desired number to slave stations 2' and 2'' and transmits the transmission start signal to slave station 2. Thus, slave station 2 puts transmission data onto line 3, and slave stations 2' and 2'' receive this data, and thus, data is transmitted through master station 1 between arbitrary slave stations.
