5W 24V Power Supply Wireless RS485 Module PLC Wireless Communication Radio
1. General Introduction
This is a 5W radio for long distance wireless data transfer. Its control distance reaches around 10km. It is widely used for PLC wireless communication. We support Modbus RTU protocol. LS-R524 DTU can be connected with transducer, HMI and sensors for wireless communication. It supports point to point, point to multi-points wireless data transmission. Wireless solution has the advantage of keep users from wiring cables in dangerous field, easy to set up, no need program knowledge. It is a reliable and competitive solution.

4. LS-R524 DTU networking
LS-R524 DTU adopts half-duplex communication mode. It suits point to multipoints communication. In this way, we should set 1 module as master and others as slaves. Each slave has its own unique ID. Master uses data frame with ID to transmit data or command. All slaves will receive data and compare the received ID with its own ID. If ID is the same, receive it and give corresponding response according the command . If ID is different, just ignore it, give no response. All these should finish by upper protocol. It can promise there is only one radio is in transmitting mode in any time to avoid interference.
LS-R524 RTU can also use for point to point communication. This is more easier. When you program serial port, please note it is half-duplex and there is wireless transmission delay.
5. LS-R524 DTU DIP switch setting
DIP3 ON means 4
DIP4 ON means 8
For example, channel 15, you need to set DIP 1, 2, 3 and 4 all ON
