### Procedure of Print Log

1. Download driver of CP2102 from the following link:

{% file src="/files/V1drgDxMOKxDhbKZi5zS" %}

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:

{% file src="/files/IpJoDeiaWnwXpkJWhXI8" %}

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.&#x20;

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 local area network;
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 encoder  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.
