Wireless transmission module based on the 433MHz frequency band development, capable of converting RS485 received data signals into wireless signals. It can communicate wirelessly with another wireless transmission module within a certain distance. The receiving end captures the wireless signal and converts it back into an RS485 signal for output. Users can deploy multiple wireless transmission modules for data transmission, eliminating the need for extensive signal cabling. The modules only require power and connection to RS485 devices to enable bidirectional data communication, making remote operation of RS485 devices convenient and helping avoid data transmission issues caused by corroded, broken, or poorly connected signal lines. The module requires setting only two parametersbaud rate and channelwhich can be configured using DIP switches. This simplifies setup and enhances user-friendliness.
