370 -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.
675 +(% style="color:blue" %)**Example to use with door sensor :**
371 371  
677 +The door sensor is shown at right. It is a two wire magnetic contact switch used for detecting the open/close status of doors or windows.

374 374  
681 +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.
375 375  
376 -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.
377 377  
378 -* a) S31x-LB will do an ACK check for data records sending to make sure every data arrive server.
379 -* 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.
684 +(% style="color:blue" %)**Below is the installation example:**

384 384  
385 -=== 2.5.2 Unix TimeStamp ===
695 +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.
386 386  
697 +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.
387 387  
388 -S31x-LB uses Unix TimeStamp format based on
699 +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.
