6.1 KSULR-100 General LORA RTU parameter setting
KSULR-100 universal LORA RTU is connected to set parameters through USB-TTL cable (purchased by yourself). After removing the soft plug on the back of the acquisition box with tweezer and removing the screw, the shell is opened and connected as shown (RXD and TXD cross connect, that is, RXD of the USB-TTL cable is connected to TXD of the acquisition box, TXD is connected to RXD of the acquisition box, and TXD is connected to RXD of the acquisition box. The VCC is shorted to the 3V3 with the shorting cap, and the GND is connected to the GND of the acquisition box)
6.1.1 Enable motherboard 485 function
open the sensorbox configuration tool > Select the corresponding com> Baud rate 9600> Click Open to open the serial port > Click AN201>Function Select> Input c in the box after AT+FUNMODE= and then click AT+FUNMODE= OK appears at the bottom left to indicate completion
6.1.2 Modify the baud rate of the sensor communication interface
Click on the box after UART>AT+UART1CFG, enter 9600> and then select 8n1. Click on OK below AT+UART1CFG to indicate completion
6.2 Set the sensor query parameters and query time
(The factory defaults to collect data every 30 minutes, and the increase in query frequency will increase power consumption).
Click AN201> Click RS485> Click AT+TRANS485MODE= rear inverted triangle select polling> click AT+TRANS485MODE= set parameters, ok> Enter 1800 in the box after AT+SAMPLEDATATIM= > Click on AT+SAMPLEDATATIM= Set parameters, ok> Enter 8 in the box after AT+REQDATA= > Enter 0103010000030437 in the box after 8> Click AT+REQDATA= set parameters, ok> AT+RESPONSETIM= input 10000 in the box after AT+RESPONSETIM= (Power supply time for sensor during each query, too short may lead to failure to obtain correct data)> Click AT+ responsetim = set parameters, ok> click AT+REBOOT appears in the bottom left. After the buzzer sounds three times, it means that the network is successfully entered, and the data can be viewed in the background.
6.3 Redirect the LoRaWAN base station
In order for the LoRaWAN base station's packets to be sent to the specified LoRa Server, it is necessary to configure the Server address for the base station.
Open the Chrome browser, input the LoRaWAN base station IP (192.168.10.99 for this example), then input the user name and password (user name =guest, password =rimelink for this example), and enter the web configuration page as shown below.
Then click LoRaWAN Server Configuration > Server Address > enter the IP (lorawan.timeddd.com /b19>) > OK. As shown in the figure below
6.4 Log in to the background to view data
Log on to http://lorawan.timeddd.com/unit/ULogin.aspx,
account number: 19240527
password: admin @ 666666
After logging in, click the data option of the corresponding ID device to view the corresponding data, and the factory set to send data every 30 minutes
The ID location is shown in the figure
The data obtained are as follows (in hexadecimal), the distance unit is 0.1mm below 6 m, the range unit is mm above 6 m, and the temperature unit is ° C. The 90th byte is the liquid level value, and the 11th byte is the temperature value. In this case, the liquid level value is 08E3, the unit is mm, and the temperature value is 001B.
