44.3	154	The SN50v3-LB is configured as (% style="color:#037691" %)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 press the button to activate the SN50v3-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

	729
	730	[[image:http://wiki.dragino.com/xwiki/bin/download/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LSN50%20%26%20LSN50-V2%20-%20LoRaWAN%20Sensor%20Node%20User%20Manual/WebHome/1656379210849-860.png?rev=1.1\|\|alt="1656379210849-860.png"]]
	731
44.2	732	When the two pieces are close to each other, the 2 wire output will be short or open (depending on the type), while if the two pieces are away from each other, the 2 wire output will be the opposite status. So we can use SN50v3-LB interrupt interface to detect the status for the door or window.
14.1	733
	734
43.46	735	(% style="color:blue" %)Below is the installation example:

14.1	744	)))
	745
36.1	746	Install the other piece to the door. Find a place where the two pieces will be close to each other when the door is closed. For this particular magnetic sensor, when the door is closed, the output will be short, and PA8 will be at the VCC voltage.
14.1	747
43.46	748	Door sensors have two types: (% style="color:blue" %) NC (Normal close)(%%) and (% style="color:blue" %)NO (normal open)(%%). The connection for both type sensors are the same. But the decoding for payload are reverse, user need to modify this in the IoT Server decoder.
14.1	749

43.9	844	(% style="color:blue" %)AT+5VT=1000
14.1	845
