PURPOSE:To execute the error detection of transferred data without fail by returning received data to a transmitter and comparing them with original data transferred earlier by the transmitter. CONSTITUTION:The data transferred from a data processor 1 at a transmitting side through a unidirectional bus 3 and received by receiving side equipment 2 are returned from the receiving side equipment 2 through a data returning path 4 to the data processor 1 at the transmitting side. By comparing the returned data and the original data earlier transferred with the data processor 1 at the transmitting side, the error of the data transferred to the receiving side equipment 2 is detected. |
