Ujjdwiurgh DC 12V 24V Din Rail DIP Switch RS485 Wireless Transceiver 20DBM -121dBm UART Transmitter and Receiver Modbus RTU Module

The modules only need to be powered on and connected to RS485 devices to achieve mutual data transmission, which is very convenient for users to operate RS485 devices at the remote end and effectively avoid the inability to transmit data due to rusty, broken or poor contact signal lines. Users can use multiple wireless transmission modules for data transmission without the need to lay too many long signal transmission lines. can be within a certain distance and the other end of the wireless transmission module for wireless communication, the other end of the wireless transmission module received wireless signal, and then converted into RS485 signal output. wireless transmission module, based on the 433M frequency band development, can be RS485 received data signal into wireless signal, The module only requires two parameters to be set, which can be set via dip switches, simplifying the parameter setting process and making it very user-friendly. The parameters that can be set are the baud rate and the channel
