Product Overview:
RT5BF01 wireless transmission module, based on the 433M frequency band development, can be RS485 received data signal into wireless signal, 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.

Users can use multiple wireless transmission modules for data transmission without the need to lay too many long signal transmission lines. 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.

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, and the dip switch settings can be found in the following selection table.
Radio frequency of the module = channel * 5.5MHz + 426MHz.

Recommend to buy more than 2pcs!!!


How to use (>=2pcs):

1 2PCS,Module 1 and Module 2 send data to each other.

3 >=3PCS,One as master device, the other as will be as slave device.
the way they work as well as wired RS485 bus. Master device transmit data, Slave devices all receive data.Any slave device transmit data, master device and the other slave devices can receive .When ever only allowed one device (master or slave) to transmit data.
