Feature

●Stable connection: you can operate the RS485 device at a remote end to prevent data transfer errors due to signal rust, interrupted connections or poor contact
●Working principle: the data signal received by RS485 can be converted into a wireless signal, wireless communication at a certain distance and the other end of the wireless transmission module, the other end of the wireless transmission module to receive a wireless signal, and then be converted into RS485 signal output
●Easy to use: the module only needs to be switched on and connected to the RS485 device to realise the data transfer among each other, which is very practical
●Easy to use: the module only needs to set two parameters that can be set via the dip switch, which simplifies the parameter setting process and is very user-friendly
●Wireless transmission: users can use multiple wireless transmission modules for data transmission without laying too many long signal transmission lines


Description

1. WIRELESS TRANSMISSION: users can use multiple wireless transmission modules for data transmission without laying too many long signal transmission lines
2. Easy to use: the module only needs to be turned on and connected to the RS485 device to realise data transfer with each other, which is very convenient
3. Stable connection: you can operate the RS485 device at a distant end to prevent data transfer errors due to signal rust, interrupted connections or poor contact
4. Easy to use: the module only needs to set two parameters, which can be adjusted via the DIP switch, which simplifies the parameter setting process, very user-friendly
5. Working principle: the data signal received by RS485 can be converted into a wireless signal, wireless communication at a certain distance and the other end of the wireless transmission module, the other end of the wireless transmission module to receive a wireless signal, and then converted into RS485 signal output
