249
250
251 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.
252
253
254 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
255
256
257 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.
258
259
260 [[image:1675144005218-297.png]]
261
262
263 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.
264
265
266 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from PS-LB.
267
268 Each PS-LB is shipped with a sticker with the default device EUI as below:

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:
