	298
123.2	299	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	477
47.1	478	The probe model field provides the convenient for server to identical how it should parse the 4~~20mA sensor value and get the correct value.
6.2	479
	480
135.1	481	When connecting to current sensors sold by our company, you can convert current readings to corresponding values by simply configuring the [[AT+PROBE>>\|\|anchor="H3.3.4SettheProbeModel"]] command. If you prefer not to configure this command on the sensor, you can uniformly handle the conversion in the payload decoder instead.
134.1	482
	483	Examples for decoder implementation:
	484
136.1	485	~1. For AT+PROBE=0005, add the following processing in your decoder:

	506
	507

	648
	649
123.2	650	~1. Through LoRaWAN MAC Command (Default settings)
93.1	651
	652	Users need to set SYNCMOD=1 to enable sync time via the MAC command.
	653
	654	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]]].
	655

93.1	657
	658
123.2	659	2. Manually Set Time
