PURPOSE:To enhance the general purposeness of an apparatus, by providing a signal change-over circuit between the interface and control circuit of a diagnostic apparatus. CONSTITUTION:When the input and output signals of a control circuit 2' are inputted to a diagnostic apparatus 4, said control circuit 2' is made connectable to a predetermined interface 5 corresponding to the kind of each of the input and output signals through a signal change-over circuit 10 changing over a signal line. As a result, the same diagnostic apparatus 4 can be used in the control circuit 2' of a measure of every kind different in the positions of the connector terminals of the input and output signals and, therefore, an exclusive diagnostic apparatus becomes unnecessary and the general purposeness of the diagnostic apparatus 4 can be enhanced. |
