245 == 2.1 How it works ==
246
247
248 The PS-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 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.
249
250
251 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
252
253
254 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.
255
256
257 [[image:1675144005218-297.png]]
258
259
260 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.
261
262
263 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from PS-LB.
264
265 Each PS-LB is shipped with a sticker with the default device EUI as below:

404
405 PS-LB 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. 
406
407
408 **For example.**

415
416 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.
417
418
419 === 2.3.5 0~~20mA value (IDC_IN) ===
420
421
422 The output value from **Pressure Probe**, use together with Probe Model to get the pressure value or water level.
423
424 (% style="color:#037691" %)**Example**:
425
426 27AE(H) = 10158 (D)/1000 = 10.158mA.
427
428
429 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:

432
433
434 === 2.3.6 0~~30V value ( pin VDC_IN) ===
435
436
437 Measure the voltage value. The range is 0 to 30V.
438
439 (% style="color:#037691" %)**Example**:
440
441 138E(H) = 5006(D)/1000= 5.006V
442
443
444 === 2.3.7 IN1&IN2&INT pin ===
445
446
447 IN1 and IN2 are used as digital input pins.
448
449 (% style="color:#037691" %)**Example**:
450
451 09 (H): (0x09&0x08)>>3=1    IN1 pin is high level.
