Chapter 1 Product Introduction
The LoRa Data Transmission Terminal, Model No.IOT-L2S-D1 is universal communication
interactive equipment which is designed and manufactured by our company based on the LoRa RF
chip. It integrates two interfaces of industrial standard RS485 and supports a variety of protocols to
realize data transmission between wired and wireless devices. It transmits the data of the wired
device to the product and then transmits the data wirelessly through RS485 communication lines.
The product can be widely applied in the IOT, centralized metering and industrial control etc.

2.4 Parameter Configuration
All the parameters of LoRaWAN series products developed by our company can be set by the user.
The setting steps are as follows:
2.4.1 Wiring
The power ports are connected into power supply of AC85-265V. Connect the RS485-1 port of the
device to the PC terminal through a RS485 converter.
The Link/ACT indicator light will flash quickly after power on, if the module accesses the Net
successfully, it will flash every two seconds.

2.4.2 Enter Configuration Mode
Method 1:
After wiring, power on and press button “Deploy” longer than 5S to make LoRa device enter the
configuration mode. After that, the LINK/ACT indicator lights flash at a fixed frequency (flashing once
per second) and release the button.
Method 2:
Press the button “Deploy” to power up the module, it will enter the configuration mode directly. And
then release the button. The Link/ACT indicator light will flash at a fixed frequency (flashing once per
second).
2.4.3 Open the Software
Open the software of LoRaWAN series products. Select the corresponding COM port in the
“Communication Connection” part, and then click “Open the Port”, like the following picture.
2.4.4 Parameters Configuration
There are six parts in the parameters configuration: internet access, serial port parameters
configuration, devices definition, register definition, upload/download data definition. Now we need
to configure the parameters of internet access & serial port.
(1)Internet Access: the unique code of LoraWAN device and Appkey cannot be modified.
(2)Serial Port Parameters Configuration: Close RS485-1 and RS485-2
Parameter Configuration Process:
After opening the serial ports, click “Read”. Then it will indicate “Completed”. If it indicates “Time Out”,
please check whether the LoRa device enters the configuration mode.
After completing operation, the host computer will read out the current configured parameters.
If you need to modify corresponding parameters, click “Write” then it will indicate “Completed”.
Click “Read” again to check whether configuration is correct. Click “Restart” to exit configuration
mode.
