Abstract

PURPOSE:To perform normal code transfer even when a fault is not removed, by performing parallel operation by superposing DC binary codes inverted in potential relation even when the fault that one potential is converted into the other is occurring. CONSTITUTION:For a logical code 1010...10 and parity bit 1 sent from a transmitting register 1, an earth potential 0V sent from terminals 7'-15 of a transmitted data selector 7 is converted into a potential V1, which is received by the received data selector 8 as DC binary code with normal potential relation and reverse potential relation. The binary code with the normal potential relation is transmitted to a receiving register 2 and parity check circuit 4 in parallel, which recognizes them as the logical code 1010...10 and 1 to perform error detecting processing. With the DC binary code with the reverse potential relation sent from the selector 7, the potential V1 is sent from the terminal 7'-15 for ''0''. Therefore, normal code transfer is performed even in case of the occurrence of the fault of the circuit 3-15 of a transmission line 3.
