123.2	300	The PS-LB/LS is configured as LoRaWAN OTAA Class A mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and activate the PS-LB/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

6.2	480
	481
134.1	482	When connecting to current sensors sold by our company, you can convert current readings to corresponding values by simply configuring the AT+PROBE command. If you prefer not to configure this command on the sensor, you can uniformly handle the conversion in the payload decoder instead.
	483
	484	Examples for decoder implementation:
	485
	486	~1. For AT+PROBE=0005, the corresponding modifications in the decoding are as follows.

123.2	651	~1. Through LoRaWAN MAC Command (Default settings)
93.1	652
	653	Users need to set SYNCMOD=1 to enable sync time via the MAC command.
	654
	655	Once CPL01 Joined the LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to CPL01. If CPL01 fails to get the time from the server, CPL01 will use the internal time and wait for the next time request ~[[[via Device Status (FPORT=5)>>url:http://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/CPL01%20LoRaWAN%20Outdoor%20PulseContact%20%20Sensor%20Manual/#H2.3.1DeviceStatus2CFPORT3D5]]].
	656

93.1	658
	659
123.2	660	2. Manually Set Time

76.2	1306	Test the current values at the depth of different liquids and convert them to a linear scale.
	1307	Replace its ratio with the ratio of water to current in the decoder.
76.1	1308
123.2	1309	Example:
76.1	1310
78.1	1311	Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
	1312
123.18	1313	Calculate scale factor:
78.1	1314	Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
	1315
123.18	1316	Calculation formula:
78.1	1317
	1318	Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
	1319
123.18	1320	Actual calculations:
78.1	1321
	1322	Use this formula to calculate the value corresponding to the current at a depth of 1.5 meters: (6.918-5.035)/1.86470588235294+0.51=1.519810726
