简介： RS-232 is a serial physical interface standard developed by the Electronic Industry Association of the United States.What is RS232 interface: asynchronous transmission standard interface.The difference between RS232 and RS485: different transmission modes, different transmission distances, RS-232 only allows one-to-one communication, 1, different transmission modes.RS-232 adopts unbalanced transmission mode, which is called single-ended communication, while RS485 adopts balanced transmission, wh
