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
