713 +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 SN50_v3 interrupt interface to detect the status for the door or window.

347 -== 2.5 Datalog Feature ==
715 +**~ Below is the installation example:**
348 348  
717 +Fix one piece of the magnetic sensor to the door and connect the two pins to SN50_v3 as follows:
349 349  
350 -Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, S31x-LB will store the reading for future retrieving purposes.
719 +* (((
720 +One pin to SN50_v3's PA8 pin
721 +)))
722 +* (((
723 +The other pin to SN50_v3's VDD pin
724 +)))
351 351  
726 +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.
352 352  
353 -=== 2.5.1 Ways to get datalog via LoRaWAN ===
728 +Door sensors have two types: ** NC (Normal close)** and **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.
354 354  
730 +When door sensor is shorted, there will extra power consumption in the circuit, the extra current is 3v3/R14 = 3v3/1Mohm = 3uA which can be ignored.
355 355  
356 -Set [[PNACKMD=1>>||anchor="H2.5.4DatalogUplinkpayloadA028FPORT3D329"]], S31x-LB will wait for ACK for every uplink, when there is no LoRaWAN network,S31x-LB will mark these records with non-ack messages and store the sensor data, and it will send all messages (10s interval) after the network recovery.
732 +[[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/1656379283019-229.png?rev=1.1||alt="1656379283019-229.png"]]
357 357  
358 -* a) S31x-LB will do an ACK check for data records sending to make sure every data arrive server.
359 -* b) S31x-LB will send data in **CONFIRMED Mode** when PNACKMD=1, but S31x-LB won't re-transmit the packet if it doesn't get ACK, it will just mark it as a NONE-ACK message. In a future uplink if S31x-LB gets a ACK, S31x-LB will consider there is a network connection and resend all NONE-ACK messages.
734 +The above photos shows the two parts of the magnetic switch fitted to a door.
360 360  
361 -Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)
736 +The software by default uses the falling edge on the signal line as an interrupt. We need to modify it to accept both the rising edge (0v ~-~-> VCC , door close) and the falling edge (VCC ~-~-> 0v , door open) as the interrupt.
