THE DATA-TRANSMITTABLE NON-POLARITY RS-485 COMMUNICATION DEVICE OF BMS CONTROLLER BY AUTOMATIC POLARITY DISCRIMINATION

摘要

PURPOSE: A non-polar RS-485 communication device capable of data transmission by automatic polarity determination for preventing error by malfunction is provided to increase the convenience of a user by transmitting data after automatically sensing polarity by a connector. CONSTITUTION: A communication rate processor(200) determines a polarity after sensing up-edge and a down-edge of the data. A line connecting processor performs normal data transmission on a wrongly connected line by an input data signal of the communication rate processor. An output coupling unit(400) transmits normal data to an MCU(Micro Controller Unit)(500).
