# Remote access via Serial Console

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

> **Note**
>
> 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 Micro USB cable from your host computer to the [Micro USB 2.0 - OTG](/docs/products/embedded/zed-box-series/zed-box-2/connectivity#micro-usb-20---otg) port on the rear panel of the ZED Box 2.

* Power on the ZED Box 2.

* On the host computer, open a terminal (`Ctrl+Alt+T`) and install `gtkterm` if not already installed:

  ```bash
  sudo apt-get install gtkterm
  ```

* Launch `gtkterm` from the terminal with the appropriate device path (usually `/dev/ttyACM0`):

  ```bash
  sudo gtkterm -p /dev/ttyACM0
  ```

  > **Info**
  >
  > 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.

  > **Note**
  >
  > If the cable is connected after the boot is complete, the terminal will 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.
