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

404 === 2.3.4 Probe Model ===
405
406
407 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. 
408
409
410 For example.
411
412 (% border="1" cellspacing="4" style="background-color:#f7faff; color:black; width:510px" %)
413 |**Part Number**|**Probe Used**|**4~~20mA scale**|**Example: 12mA meaning**
414 |PS-LB-I3|immersion type with 3 meters cable|0~~3 meters|1.5 meters pure water
415 |PS-LB-I5|immersion type with 5 meters cable|0~~5 meters|2.5 meters pure water
416 |PS-LB-T20-B|T20 threaded probe|0~~1MPa|0.5MPa air / gas or water pressure
417
418 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.
419
420
421 === 2.3.5 0~~20mA value (IDC_IN) ===
422
423
424 The output value from **Pressure Probe**, use together with Probe Model to get the pressure value or water level.
425
426 (% style="color:#037691" %)**Example**:
427
428 27AE(H) = 10158 (D)/1000 = 10.158mA.
429
430
431 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:

444
445
446 === 2.3.7 IN1&IN2&INT pin ===

734 When aa=01, it is the pressure mode, which converts the current into a pressure value;
735
736 bb represents which type of pressure sensor it is.
