477 +Once all the data has been uploaded to the TTN platform, the subsequent step involves concatenating each packet in sequential order and saving it into a new TXT file. It is important to note that the first 8 bytes of each packet should be removed before concatenation.
466 466  
479 +When you combine all the packets, you need to convert the data inside to binary. Here the conversion is demonstrated using the [[WinHex>>http://www.x-ways.net/winhex/index-m.html]] software.

481 +Open WinHex to open the combined image data file.

505 +=== 3.2.2 Get the current image packet by connecting the AUC USB TTL adapters for AIS Sensors to the AIS Sensor. ===
506 +
507 +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
508 +
509 +
510 +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
511 +
512 +
513 +Then follow the instructions in 3.2.1.6 to get the image from AIS Sensor.
