#163406 - Biometric Reader |
I am trying to interface a Biometric reader with RS485 interface to a 8052 based controller. The guy who sold me the reader does not have clue on the RS485 protocol used. The reader also does not have any detailed markings for me to contact the manufacturer.
Is there a standard protocol for these access readers? I will be thankful if some one on the forum can help me out regards Shankara Rao |
