发明名称 EMULATION DEVICE
摘要 PURPOSE:To prevent the inserting direction to the IC socket of a connector from being limited by providing a compensating switch circuit to compensate and connect corresponding to the inserting direction between an emulation circuit part and the connector. CONSTITUTION:A connector 1 has taper parts Q1 to Q4 at four angles, can be be connected in any direction of four directions of an IC socket 4 on a target system 3. A compensating switch circuit 5 is composed of four interlocking switch groups SWa to SWd, and when signals Sa to Sd are connected to a contact group (a), they are supplied to the pin of the corresponding number of four sides of the connector 1 and the socket 4 through the wiring A' to D' of the cable 2. The circuit 5 can be connected and compensated by switching the contact group of respective switch groups corresponding to four directions of the insertion of the connector 1. Consequently, concerning four sides of the socket 4, even when the connector is inserted in any direction, the communication can be executed corresponding to it and the insertion direction to the socket 4 of the connector 1 cannot be limited.
