Introduction:

LS-R324 is a 1W radio modem, transmit 3km LOS. It supports UHF band, 24V power supply. Usually works as DTU to connect with PLC and other industrial control devices. LS-R324 Supports RS485 Modbus RTU protocol. Has the advantage of register data restore function.

Application:

• Water/waste water treatment field

• Wind speed, rainfall, humidity etc data collection

• Temperature, humidity, concentrations of CO2 etc data collection

• Wireless data collection and transmission

• Wireless communication between PLC and sensors

About channel setting

Channel No.	DIP Setting	Channel No.	DIP Setting	Channel No.	DIP setting	Channel No.	DIP setting
1	1234	2	1234	3	1234	4	1234
5	1234	6	1234	7	1234	8	1234

DIP1 ON means 1

DIP2 ON means 2

DIP3 ON means 4

DIP4 ON means 8

For example, channel 15, you need to set DIP 1, 2, 3 and 4 all ON




About the LED indicator

a. When module is power on, POWER LED is always ON (red).

b. When module enter to set mode (DIP 8 ON), SET LED is always ON (red).

c. When module is transmitting,

    if you use RS232 port, RS232 LED blinks (green) regularly.

    if you use RS485 port, RS485 LED blinks (green) regularly.

    if you use USB port, USB LED blinks (green) regularly.

d. When module is receiving, RF LED blinks (blue) regularly.




Advantage of wireless solution

- No wires to bury or maintain, no need to drill holes on wall

- Reliable communication in all direction,any terrain, regardless of hills, walls, trees

- Cost saving in installation and maintenance

- Radio based, no need internet and monthly fee, full ownership of the system

- 4G based, high speed, no distance limit
