Patent ID: 7490277

Claim:
A peripheral connector comprising: a peripheral signal terminal set for electrically connecting a peripheral interface of a microcomputer; a test signal terminal set for electrically connecting a boundary scan interface of the microcomputer; a socket having an input terminal set for electrically connecting one of a peripheral device compatible to the peripheral interface and a test module compatible to the boundary scan interface, a switching terminal set for detecting one of the peripheral device and the test module that is electrically connected to the input terminal set and outputting an electric potential corresponding to the detected result, and a transmission terminal set which is a digital data transmission interface electrically connected to the peripheral signal terminal set; and a converting unit having a logic circuit and a transmission circuit; wherein the transmission terminal set and the test signal terminal set are electrically coupled by the transmission circuit for enabling the test module to conduct a boundary scan test on the microcomputer; wherein the logic circuit is electrically connected to the switching terminal set and the transmission circuit for converting the outputted electric potential of the switching terminal set into a digital control signal for controlling enablement or disablement of the transmission circuit.
