254
255 == 2.1 How it works ==
256
257
258 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.
259
260
261 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
262
263
264 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.
265
266
267 [[image:1675144005218-297.png]]
268
269
270 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.
271
272
273 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from PS-LB.
274
275 Each PS-LB is shipped with a sticker with the default device EUI as below:
276
277 [[image:image-20230426085320-1.png||height="234" width="504"]]

414 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. 
415
416
417 **For example.**

424
425 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.
426
427
428 === 2.3.5 0~~20mA value (IDC_IN) ===
429
430
431 The output value from **Pressure Probe**, use together with Probe Model to get the pressure value or water level.
432
433 (% style="color:#037691" %)**Example**:
434
435 27AE(H) = 10158 (D)/1000 = 10.158mA.
436
437
438 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:

441
442
443 === 2.3.6 0~~30V value ( pin VDC_IN) ===
444
445
446 Measure the voltage value. The range is 0 to 30V.
447
448 (% style="color:#037691" %)**Example**:
449
450 138E(H) = 5006(D)/1000= 5.006V
451
452
453 === 2.3.7 IN1&IN2&INT pin ===
454
455
456 IN1 and IN2 are used as digital input pins.
457
458 (% style="color:#037691" %)**Example**:
459
460 09 (H): (0x09&0x08)>>3=1    IN1 pin is high level.
461
462 09 (H): (0x09&0x04)>>2=0    IN2 pin is low level.
