Power ON Device 151 - 152 - 153 -The LT controller can be powered by 7 ~~ 24V DC power source. Connect VIN to Power Input V+ and GND to power input V- to power the LT controller. 154 - 155 -PWR will on when device is properly powered. 156 - 157 -[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image004.png]] 158 - 159 - 160 - 161 - 162 - 163 -1. Operation Mode 164 -11. How it works? 165 - 166 -The LT is configured as LoRaWAN OTAA Class C mode by default. It has OTAA keys to join network. To connect a local LoRaWAN network, user just need to input the OTAA keys in the network server and power on the LT. It will auto join the network via OTAA. For LT-22222-L, the LED will show the Join status: After power on TX LED will fast blink 5 times, LT-22222-L will enter working mode and start to JOIN LoRaWAN network. TX LED will be on for 5 seconds after joined in network. When there is message from server, the RX LED will be on for 1 second. 167 - 168 - 169 -In case user can’t set the OTAA keys in the network server and has to use the existing keys from server. User can [[use AT Command>>path:#AT_Command]] to set the keys in the devices. 170 - 171 - 172 -1. 173 -11. Example to join LoRaWAN network 174 - 175 -This chapter shows an example for how to join the TTN LoRaWAN Network.

So what we need to do now is only configure register this device to TTN: 181 - 182 -**Step 1**: Create a device in TTN with the OTAA keys from LT IO controller. 183 - 184 -Each LT is shipped with a sticker with the default device EUI as below: 185 - 186 -[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image006.png]] 187 - 188 - 189 - 190 - 191 -Input these keys in the LoRaWAN Server portal.

After join success, it will start to upload message to TTN and user can see in the panel. 202 - 203 -[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image009.png]] 204 - 205 - 206 -1. 207 -11.
