Patent ID: 8185329

Claim:
A system for testing matrix type connector, comprising: a data collecting circuit capable of collecting pin' information from a matrix type connector; a storage unit that stores a plurality of normal pins' information; wherein the storage unit comprises an electrically erasable programmable read-only memory (EEPROM), the EEPROM has a serial clock terminal, a serial data terminal, and a write-protect terminal; the write-protect terminal is grounded via a jumper device; a control circuit capable of receiving the collected pins' information, comparing the collected pins' information with the stored normal pins' information, and outputting a comparison result; wherein the control circuit comprises a microcontroller having a first data input pin and a second data input pin which are electrically coupled to the serial clock terminal and serial data terminal respectively; a switch unit electrically coupled to the control circuit capable of inputting a password into the control circuit to store the plurality of normal pins' information in the storage unit; and a display unit capable of receiving the comparison result and indicating whether pins of the matrix type connector are normal.
