315 +Assume the DLOS8 is already set to connect to [[TTN V3 network >>url:https://eu1.cloud.thethings.network/]]. We need to add the AIS Sensor device in TTN V3 portal. 
316 316  
317 -Select the corresponding baud rate and serial port number through the serial port tool, select HEX display and HEX send, and continuously receive data from the AIS Sensor
317 +**Step 1**:  Create a device in TTN V3 with the OTAA keys from AIS Sensor.

321 -In the serial port to send data C0 5A 00 00 00 00 04, and then send C0 5A 00 00 00 00 09, AIS Sensor will send a real-time image of the data packet, and then stop sending. Start with FFD8 and put it in TXT file

329 +Add APP KEY and DEV EUI
