Claims

[Claims for Utility Model Registration] 1. A system having a control device having a single serial signal output terminal and a plurality of measuring instruments each having a single serial signal input terminal; In a measuring device in which measuring instruments are controlled by the same control signal, each of the plurality of measuring instruments is provided with a serial signal passing terminal via a buffer, and the serial signal passing terminal of the preceding measuring instrument and its serial signal passing terminal are provided. The plurality of measuring instruments are continuously connected by connecting the serial signal input terminals of the next stage through respective transmission lines, and the serial control signal from the serial signal output terminal of the control device is continuously connected. The measuring device is characterized in that the serial control signal is supplied to the serial signal input terminal of a first-stage measuring device among the plurality of measuring devices arranged in a row, so that the serial control signal is sequentially transmitted to the plurality of measuring devices. 2 It has a control device equipped with a single serial signal output terminal and a plurality of measuring instruments each equipped with a single serial signal input terminal, and the control device controls the plurality of measuring instruments with the same control signal. In the measuring device, each of the plurality of measuring devices is provided with an input/output circuit connected to the serial signal input terminal and a serial signal output terminal connected to the input/output circuit, and the control device A single serial signal input terminal is provided in the measuring instrument at the previous stage, and the serial signal input terminal of the measuring instrument at the next stage is connected through a transmission path, respectively. The serial control signal from the serial signal output terminal of the control device is supplied to the serial signal input terminal of the first measuring instrument among the plurality of continuously connected measuring instruments. , the serial control signal is sequentially transmitted to the plurality of measuring devices, and the serial measurement signals from the plurality of measuring devices are transmitted through the same transmission path as the transmission path of the serial control signal, and the continuously connected plurality of measuring devices are A measuring device characterized in that the plurality of serial measurement signals from a final-stage measuring device among the measuring devices are supplied to the serial signal input terminal of the control device.
