298
299 == 2.1 How it works ==
300
301
302 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.
303
304
305 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
306
307
308 Following is an example for how to join the [[TTN v3 LoRaWAN Network>>url:https://console.cloud.thethings.network/]]. Below is the network structure; we use the [[LPS8v2>>url:https://www.dragino.com/products/lora-lorawan-gateway/item/228-lps8v2.html]] as a LoRaWAN gateway in this example.
309
310 [[image:1675144005218-297.png]]
311
312
313 The LPS8V2 is already set to connected to [[TTN network >>url:https://console.cloud.thethings.network/]], so what we need to now is configure the TTN server.
314
315
316 Step 1: Create a device in TTN with the OTAA keys from PS-LB/LS.
317
318 Each PS-LB/LS is shipped with a sticker with the default device EUI as below:
319
320 [[image:image-20230426085320-1.png||height="234" width="504"]]
321
322
323 You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:

345
346 Step 2: Activate on PS-LB/LS
347
348
349 Press the button for 5 seconds to activate the PS-LB/LS.
350
351 Green led will fast blink 5 times, device will enter OTA mode for 3 seconds. And then start to JOIN LoRaWAN network. Green led will solidly turn on for 5 seconds after joined in network.
352
353 After join success, it will start to upload messages to TTN and you can see the messages in the panel.

361 Include device configure status. Once PS-LB/LS Joined the network, it will uplink this message to the server.
362
363 Users can also use the downlink command(0x26 01) to ask PS-LB/LS to resend this uplink.

455 === 2.3.4 Probe Model ===
456
457
458 PS-LB/LS has different kind of probe, 4~~20mA represent the full scale of the measuring range. So a 12mA output means different meaning for different probe. 
459
460
461 For example.
462

468
469 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.
470
471
472 === 2.3.5 0~~20mA value (IDC_IN) ===
473
474
475 The output value from Pressure Probe, use together with Probe Model to get the pressure value or water level.
476
477 Example:
478
479 27AE(H) = 10158 (D)/1000 = 10.158mA.
480
481
482 Instead of pressure probe, User can also connect a general 4~~20mA in this port to support different types of 4~~20mA sensors. below is the connection example:

563
564 Step 1: Be sure that your device is programmed and properly connected to the network at this time.
565
566 Step 2: To configure the Application to forward data to DATACAKE you will need to add integration. To add the DATACAKE integration, perform the following steps:

604
605
606 === 2.6.1 Unix TimeStamp ===
607
608
609 PS-LB uses Unix TimeStamp format based on
610
611 [[image:image-20250401163826-3.jpeg]]
612
613 Users can get this time from the link:  [[https:~~/~~/www.epochconverter.com/>>url:https://www.epochconverter.com/]] :
614
615 Below is the converter example:
616

618
619
620 === 2.6.2 Set Device Time ===
621
622
623 There are two ways to set the device's time:
624
625
626 ~1. Through LoRaWAN MAC Command (Default settings)
627
628 Users need to set SYNCMOD=1 to enable sync time via the MAC command.
629
630 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]]].
631
632 Note: LoRaWAN Server needs to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature.
633
634
635 2. Manually Set Time
636
637 Users need to set SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.
638
639
640 === 2.6.3 Poll sensor value ===
641
642 Users can poll sensor values based on timestamps. Below is the downlink command.

648 Timestamp end
649 )))|(% style="background-color:#f2f2f2; width:163px" %)Uplink Interval
650
651 Timestamp start and Timestamp end-use Unix TimeStamp format as mentioned above. Devices will reply with all data logs during this period, using the uplink interval.
652
653 For example, downlink command[[image:image-20250117104812-1.png]]
654
655 Is to check 2024/12/20 09:34:59 to 2024/12/20 14:34:59's data

687
688 Poll Message Flag: 1: This message is a poll message reply.
689
690 * Poll Message Flag is set to 1.
691
692 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
693
694 For example, in US915 band, the max payload for different DR is:
695
696 a) DR0: max is 11 bytes so one entry of data
697
698 b) DR1: max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
699
700 c) DR2: total payload includes 11 entries of data
701
702 d) DR3: total payload includes 22 entries of data.
703
704 If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0

1138
1139 Format: Command Code (0x07) followed by 3 bytes.
1140
1141 The first byte is which power, the second and third bytes are the time to turn on.
1142
1143 * Example 1: Downlink Payload: 070101F4  ~-~-->  AT+3V3T=500
1144 * Example 2: Downlink Payload: 0701FFFF   ~-~-->  AT+3V3T=65535
1145 * Example 3: Downlink Payload: 070203E8  ~-~-->  AT+5VT=1000

1148 * Example 6: Downlink Payload: 07030000  ~-~-->  AT+12VT=0
1149
1150 Note: Before v1.2, the maximum settable time of 3V3T, 5VT and 12VT is 65535 milliseconds. After v1.2, the maximum settable time of 3V3T, 5VT and 12VT is 180 seconds.
1151
1152 Therefore, the corresponding downlink command is increased by one byte to five bytes.
1153

1278 == 6.4 How to measure the depth of other liquids other than water? ==
1279
1280
1281 Test the current values at the depth of different liquids and convert them to a linear scale.
1282 Replace its ratio with the ratio of water to current in the decoder.
1283
1284 Example:
1285
1286 Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
1287
1288 Calculate scale factor:
1289 Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
1290
1291 Calculation formula:
1292
1293 Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
1294
1295 Actual calculations:
1296
1297 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
