Abstract

PURPOSE:To avoid mis-response to the transmission data to other stations, by taking synchronism until the transmission data is ended, if the transmission data from the center is not the start sequence to the station itself. CONSTITUTION:The transmission data fetched from the line 3 is fed to the reception buffuer via the MODEM 11, where serial parallel conversion is made and the synchronizing signal is retrieved. When the synchronism is established, CPU 15 reads in the data by one character to discriminate the SA of the station(station address). If SA, one more character is succeedingly read in to discriminate the UA of station (unit address). When the next reception data is the transmission control character ENQ, the data processing is started according to the start sequence of the station. If SA is not the station, the data is discriminated to other stations. If other station's data, synchronism is kept until the control sentence representing the end of the data is inputted to avoid response until the data transmission to other stations is finished.
