# Remote access via Serial Console

The ZED Box Orin provides a Serial Console interface for low-level access to the system, via the Micro USB2.0 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

* Power on the ZED Box Orin.

* Connect a Micro USB cable from your host computer to the Micro USB2.0 - OTG port.

  > **Warning**
  >
  > Do not connect the cable before the device is powered on, otherwise the ZED Box Orin will boot in [Recovery Mode](/docs/products/embedded/zed-box-orin/reset-update/#force-the-zed-box-in-recovery-mode).

* 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 just after 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 when the boot procedure is completed, 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.
