| Abstract: | A full-isolated convertor for RS-232 to RS-485 series communication is introduced.The paper deals with the construction and working principle. This convertor can enhance the capability of anti-disturbance in the series communication for collected-distributed systems,and isolating grounds between the up-system and the dow-system,enhancing the capability of anti -disturbance in systems. |
