252
253 == 2.1 How it works ==
254
255
256 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.
257
258
259 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
260
261
262 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.
263
264
265 [[image:1675144005218-297.png]]
266
267
268 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.
269
270
271 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from PS-LB.
272
273 Each PS-LB is shipped with a sticker with the default device EUI as below:
274
275 [[image:image-20230426085320-1.png||height="234" width="504"]]

412 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. 
413
414
415 **For example.**

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