PURPOSE:To realize the data transmission of high reliability, by n times of repetition of 2 series time sharing for the address and data signal, taking one as the inversion logic signal having the delay time, and discriminating the signal coincidence of 2 series at the reception side with the principle of decision by majority. CONSTITUTION:In each transmission line 5, 6, the both signals of address and data are in time sharing, it is repeated by n times, and transmission is made at the positive logic for the first tramsission line 5 and at the negative logic having time delay to the first signal for the second transmission line 6. After converting the negative logic signal into positive logic signal at the reception side 200, the transmission signal of the both is made for the detection of coincidence to each of address and data. If not in agreement, the transmission signal is confirmed with the principle of decision by majority, and if it is not determined by the principle, the signal retransmission request is made to the transmission side 100 to prevent the signal error in transmission. |
