Abstract

PURPOSE:To ensure the detection of the fault and the data error for the nonsynchronous data transmission device by giving the supervisory to the data transmission necessary time and at the same time giving a comparison between the transmission and reception data. CONSTITUTION:Transmitter side check sum data production part 3 produces the check sum data from the transmission data and then applies it to the transmission data for transmission to reception part from transmission part 4. While the prescribed value of the transmission necessary time required for the transmission of this time is set to diagnosis counter 6 at part 5, and this prescribed value is supervised at transmission device supervisory part 7. At the same time, a comparison is given at check sum data comparison part 8 between the check sum signal of the transmission time and the check sum data produced from the reception data. And in case no coincidence is obtained through the comparison, the occurrence of some error is decided to the transmisson data for the process. And in case the transmission time is longer than the prescrived value, the fault of the transmission device is judged to be processed. In such way, both the fualt of the device and the error of the transmission data can be detected.
