Remote access via Serial Console

The ZED Box 2 Max provides a Serial Console interface for low-level access to the system, via its USB 2.0 Type-C debug port. This is useful when no display is connected to the HDMI ports.

The Serial Console is available only when the device is:

Booting up
Booted into Normal Mode (not Recovery Mode)

Connecting to the Serial Console

Connect a USB Type-C cable from your host computer to the USB 2.0 Type-C port labeled Debug on the rear panel of the ZED Box 2 Max.
Power on the ZED Box 2 Max.
On the host computer, open a terminal (Ctrl+Alt+T) and install gtkterm if not already installed:
```
sudo apt-get install gtkterm
```
Identify the serial device of the ZED Box 2 Max:
```
ls /dev/ttyUSB*
```
The debug port uses a USB-to-UART bridge, detected by the host as a /dev/ttyUSB<n> device.
Launch gtkterm from the terminal with the appropriate device path (usually /dev/ttyUSB0) and a baud rate of 115200:
```
sudo gtkterm -p /dev/ttyUSB0 -s 115200
```
You can use other terminal emulators such as minicom or screen if you prefer.
If the cable is connected before the device is powered on, the terminal will display the boot messages as the device starts up. When the boot is complete, you will see a login prompt.

If the cable is connected after the boot procedure has completed, the terminal does not display any boot messages; you may need to press Enter a couple of times to see the login prompt.
Log in with your credentials (default credentials: user/admin)
You can now execute commands on the device via the Serial Console in the same way as you would via SSH.
