Procedure of Print Log

1. Download driver of CP2102 from the following link
  1. CP210x_Drivers
2. Install driver of CP2102 by double clicking the compressed file->CP2102_Drivers_Win10->double clik "CP210xVCPInstaller_x64.exe" to install directly
3. Go to Device Manager->Click Ports (COM & LPT)->Check Silicon Labs CP210x USB to UART Bridge (COM19):
4. Get encoder and Axis IP Camea (one by one)connected to the same router or switch and make sure they're on the same local area network;
5. Pull RTSP Stream of Axis IP Camera (one by one) into the encoder  directly no matter whether it's successfully streaming in the encoder;
6. Download PuTTY from following link:
  1. PuTTY
7. Run PuTTY->Select "Serial"->Serial Line"COM19"->Speed "115200"
8. Select Logging->Printable Output->Click"Browse"->Rename the file of log->Save->Click "Open"->Then it'll start printing the log, if it always prints one same error like gpio_i2c_failed->Then click "EXIT" to save this log.
9. Once done, then power off all devices, connect another AXIS IP Camera and do it again. 

Print Log via CGI

  1. Get encoder and Axis IP Camea (one by one)connected to the same router or switch and make sure they're on the same network segment;
  2. Modify the IP address (192.168.1.64 for example), username(admin) and password (12345) for the encoder via Device Manager;
  3. Pull RTSP Stream of Axis IP Camera (one by one) into the codec directly no matter whether it's successfully streaming in the encoder;
  4. Run a browser like Chrome and enter the following CGI command in the browser's Address field: http://192.168.1.64/cgi/download?file=log&user=admin&pwd=12345, then save the log;
  5. Then connect another AXIS IP Camera and do it again.
Info
🧙TIPS: If you're experiencing any problem with this encoder or codec, it'll be okay to print the log via CGI by following the above or below steps:
  1. Get the encoder or codec connected to the same router or switch and make sure they're on the same network segment;
  2. Modify the IP address (192.168.1.64 for example), username(admin) and password (12345) for the encoder via Device Manager if required;
  3. Focus on the problem you're experiencing and trying to figure out how to reproduce it;
  4. Run a browser like Chrome and enter the following CGI command in the browser's Address field: http://192.168.1.64/cgi/download?file=log&user=admin&pwd=12345
  5. It's very important to note that it'll be much better to run the above CGI command when the problem is being reproduced.
