1.Introduction:
The RS232 to RS485 module is an electronic module used to realize the media conversion between RS232 and RS485 protocols. RS232 and RS485 are two different interfaces, and RS-232 can only transmit 10 meters. In the case of long communication distances, it is usually necessary to convert RS232 signals into RS485 signals. Because the RS-485 interface can transmit up to 1200 meters. It is widely used in various industrial automation control, LED display, intelligent building monitoring, power and electrical and other fields.
