PURPOSE:To improve the processing efficiency by sending a synchronizing signal and a data signal from a transmission side communication equipment, receiving both synchronizing signal and information signal at a reception side and detecting the reception timing of each communication equipment in the synchronizing timing based on the synchronizing signal to receive the information. CONSTITUTION:The synchronizing signal S is a prescribed frequency signal and sent to the reception side via a synchronizing bus CB. A data signal at the sending side is a signal (unipole NRZ code) where a command D1 representing the head of data, a data D2 and a command D3 representing the end are composed incorporatedly, the reception is started by receiving the head command D1 at the reception side and the end of reception is detected by using the end command D3. The signal as above is sent to the synchronizing bus CB and the data bus DB as a data signal from a buffer memory 13A and a synchronizing signal from a sender side communication controller 12A and the reception side receives a data in the timing by the synchronizing signal. |
