PURPOSE:To ensure effective tansmission of data, by transmitting all data to be transmitted before the primary station tramsmits a instruction with prescribed bits to the plural secondary stations to accelerate transmission of data to the secondary stations, simultaneously decreasing the number of times of transmitting/receiving of confirming bits. CONSTITUTION:The primary station P starts transmission of transmission data IDT10, IDT11 and IDT20 to the secondary stations. In this case, the station P transmits a signal SP to a station S1 of the remote side after transmitting its transmission data to stations S1 and S2. Then a signal SF is sent back from a secondary station S2. In such a way, the data are all transmitted to the stations of remote side while the station P owns the right of transmission, and then the transmission is confirmed. Then data IDT12 and IDT21 are transmitted, and transmission and reception of signals SP and SF is carried out to each station. |
