Abstract

PURPOSE:To reduce the number of wirings required between a connector and a main body, by constituting a decoding circuit and a multiplex circuit so that they are installed to the connector. CONSTITUTION:The indication signal given from the input selection address terminal 3 is interpreted at the interpretation circuit 2, and one signal is at low impedance state with the result of interpretation and all other signals are at high impedance state. By sequentially changing the signal from the terminal, the signal of the terminal group 1 is selected in time sharing at the multiplex circuit 4 based on the instruction of the multiplex instruction signal, and it is sequentially fed to the test unit in the order of selection. Based on the result of test fed from this test unit, the electric conduction of tested material 10 and nonconductive state are detected and the judgement of propriety and analysis of the defective part can be made.
