270 +1. Configure PS-LB to connect to LoRaWAN network
271 +11. How it works
272 +
273 +The PS-LB 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. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
274 +
275 +
276 +1.
277 +11. ​Quick guide to connect to LoRaWAN server (OTAA)
278 +
279 +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.
280 +
281 +
282 +[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image003.png]]
283 +
284 +
285 +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.
286 +
287 +
288 +**Step 1**: Create a device in TTN with the OTAA keys from PS-LB.
289 +
290 +Each PS-LB is shipped with a sticker with the default device EUI as below:
291 +
292 +

294 +
295 +
296 +
297 +
298 +
299 +You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:

322 +
323 +
324 +**Step 2**: Activate on PS-LB
325 +
326 +
327 +Press the button for 5 seconds to activate the PS-LB.
328 +
329 +
330 +**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.
331 +
332 +
333 +After join success, it will start to upload messages to TTN and you can see the messages in the panel.

343 +
344 +Uplink payloads have two types:
345 +
346 +* Distance Value: Use FPORT=2
347 +* Other control commands: Use other FPORT fields.
348 +
349 +The application server should parse the correct value based on FPORT settings.
350 +
351 +
352 +
353 +1.
354 +11.
355 +111. Device Status, FPORT=5
356 +
357 +Include device configure status. Once PS-LB Joined the network, it will uplink this message to the server.
358 +
359 +
360 +Users can also use the downlink command(0x26 01) to ask PS-LB to resend this uplink.

463 +11.
464 +111. Probe Model
465 +
466 +PS-LB has different kind of probe, 0~~20mA represent the full scale of the measuring range. So a 15mA output means different meaning for different probe. 
467 +
468 +
469 +For example.
470 +
471 +|**Part Number**|**Probe Used**|**0~~20mA scale**|**Example: 10mA meaning**
472 +|PS-LB-I3|immersion type with 3 meters cable|0~~3 meters|1.5 meters pure water
473 +|PS-LB-I5|immersion type with 5 meters cable|0~~5 meters|2.5 meters pure water
474 +
475 +The probe model field provides the convenient for server to identical how it should parse the 0~~20mA sensor value and get the correct value.
476 +
477 +
478 +1.
479 +11.
480 +111. 0~~20mA value (IDC_IN)
481 +
482 +The output value from Pressure Probe, use together with Probe Model to get the pressure value or water level.
483 +
484 +
485 +**Example**:
486 +
487 +27AE(H) = 10158 (D)/1000 = 10.158mA.
488 +
489 +
490 +1.
491 +11.
492 +111. 0~~30V value ( pin VDC_IN)
493 +
494 +Measure the voltage value. The range is 0 to 30V.
495 +
496 +
497 +**Example**:
498 +
499 +138E(H) = 5006(D)/1000= 5.006V

501 +
502 +1.
503 +11.
504 +111. IN1&IN2&INT pin
505 +
506 +
507 +IN1 and IN2 are used as digital input pins.
508 +
509 +**Example**:
510 +
511 +09 (H) :(0x09&0x08)>>3=1    IN1 pin is high level.
512 +
513 +09 (H) :(0x09&0x04)>>2=0    IN2 pin is low level.
514 +

846 +1. Battery & how to replace
847 +11. Battery Type
848 +
849 +PS-LB is equipped with a [[8500mAH ER26500 Li-SOCI2 battery>>url:https://www.dragino.com/downloads/index.php?dir=datasheet/Battery/ER26500/]]. The battery is un-rechargeable battery with low discharge rate targeting for 8~~10 years use. This type of battery is commonly used in IoT target for long-term running, such as water meter.
850 +
851 +
852 +The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.
853 +
854 +[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image031.png]]
855 +
856 +
857 +Minimum Working Voltage for the PS-LB:
858 +
859 +PS-LB:  2.45v ~~ 3.6v
860 +
861 +
862 +1.
863 +11. Replace Battery
864 +
865 +Any battery with range 2.45 ~~ 3.6v can be a replacement. We recommend to use Li-SOCl2 Battery.
866 +
867 +And make sure the positive and negative pins match.
868 +
869 +
870 +
871 +1.
872 +11. Power Consumption Analyze
873 +
874 +Dragino Battery powered product are all runs in Low Power mode. We have an update battery calculator which base on the measurement of the real device. User can use this calculator to check the battery life and calculate the battery life if want to use different transmit interval.
875 +
876 +
877 +Instruction to use as below:
878 +
879 +
880 +Step 1: Downlink the up-to-date DRAGINO_Battery_Life_Prediction_Table.xlsx from:
881 +
882 +[[https:~~/~~/www.dragino.com/downloads/index.php?dir=LoRa_End_Node/Battery_Analyze/>>url:https://www.dragino.com/downloads/index.php?dir=LoRa_End_Node/Battery_Analyze/]]
883 +
884 +
885 +Step 2: Open it and choose
886 +
887 +* Product Model
888 +* Uplink Interval
889 +* Working Mode
890 +
891 +And the Life expectation in difference case will be shown on the right.

913 +111. ​Battery Note
914 +
915 +The Li-SICO battery is designed for small current / long period application. It is not good to use a high current, short period transmit method. The recommended minimum period for use of this battery is 5 minutes. If you use a shorter period time to transmit LoRa, then the battery life may be decreased.
916 +
917 +
918 +1.
919 +11.
920 +111. ​Replace the battery
921 +
922 +You can change the battery in the PS-LB.The type of battery is not limited as long as the output is between 3v to 3.6v. On the main board, there is a diode (D1) between the battery and the main circuit. If you need to use a battery with less than 3.3v, please remove the D1 and shortcut the two pads of it so there won’t be voltage drop between battery and main board.
923 +
924 +
925 +The default battery pack of PS-LB includes a ER26500 plus super capacitor. If user can’t find this pack locally, they can find ER26500 or equivalence, which will also work in most case. The SPC can enlarge the battery life for high frequency use (update period below 5 minutes)
