Abstract
In a control system for peripheral devices, by operating only one device for digital-to-analogue conversion, the specific output switching corresponding to that specific device for digital-to-analogue conversion is closed and the other output switching corresponding to the other device for digital-to-analogue conversion are open so that the only the output signal of that specific device for digital-to-analogue conversion can be output. Thus, the accuracy of operation of each device for digital-to-analogue conversion can be easily evaluated.
