476 +
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.
478 +
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.
480 +
481 +Open WinHex to open the combined image data file.
482 +
483 +[[image:1714467040612-103.png||height="134" width="649"]]
484 +
485 +Click on the edit option to choose and convert.
486 +
487 +[[image:1714467065723-178.png||height="349" width="762"]]
488 +
489 +Choose the Hex ASCII->Binary option and then click OK.
490 +
491 +[[image:1714467089355-837.png||height="366" width="336"]]
492 +
493 +After the conversion is finished, click on "File" and choose "Save As".

501 +Open the saved JPG file to display the image transmitted by the AIS Sensor through the serial port.

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.
