Smart Cable Aids Quality Control and Authentication
By wordpainter Nov 7th, 2009
|
Cable authentication problem are very common. Embedding a DS2431 (1-Wire) chip in the near end of a cable allows a system processor to identify a cable (manufacturing date, revision, configuration, calibration data, etc.) and to authenticate it (to prevent the use of inferior counterfeits). |
