Abstract

PURPOSE:To detect whether or not the data of a digital part are normally transmitted to an analog part by turning back-checking the transmitting data from the digital part to the analog part. CONSTITUTION:When data are inputted to a serial/parallel converter 6, one bit of the inputted data is presently turned back as checking data CDT through a second photocoupler 8. When all bits of the parallel data of the digital part are transmitted to the analog part, all bits of the parallel data transmitted to the analog part are turned back to a control circuit 9 of the digital part. By comparing the turned back data and the data stored by the control circuit 9, it can be detected that the data transmitted at this time are normally transmitted from the digital part to the analog part.
