PURPOSE:To enable the use of several kinds of cards to be inspected with one adaptor card, by setting an input control of an analog switch IC by an output data of an ROMIC to connect the switch 1C conductively to a desired conductive pin of a connector. CONSTITUTION:ROMICs 1-8, analog switches IC 9-24, a resistance R1, a resistance module R2 and a switch ASASY 8 are provided on a substrate 1 of an adaptor card. Then, the switching control is set for the analog switches IC by an output data of the ROMIC into which a logical pattern is memorized beforehand. According to the input set pattern, a switch in the analog switch IC is actuated to connect the analog switch IC conductively to conductive ins a1-a4 in a connector receptacle 2 on the top of the substrate 1 while it is connected conductively to conductive pins b1-b4 in a connector plug 3 at the bottom thereof 1 with the output thereof IC. This permits pin number of several kinds of cards to be inspected to coincide with pin number on the side of an inspector with one sheet of adaptor card. |
