The system offers two authorization methods: via the serial console (UART RS232) or via Ethernet (SSH).

Serial connection (UART RS232)​

A USB-to-Serial adapter and a PC are required. The following adapter configurations are available:

USB-to-Serial adapter with a DB9 connector and an RG-45 to DB9 adapter cable A direct-connect USB-to-Serial adapter and an RG-45 cable. For example:

Tested adapter options:

  • MOXA UPort 1100
  • UGREEN USB to RS-232 DB9 Serial Adapter Cable

Connection instructions:

  1. Connect the adapter to the cable according to the interface pinout. When using a pre-made adapter cable, ensure that the interface connections match the pinout diagram.

    ATTENTION!

    If connected incorrectly, the device may be damaged.

  2. Install a program for connecting to a serial console on your PC, such as minicom for GNU/Linux or PuTTY for Windows.

  3. Connect the adapter to the USB port on your PC and the SERIAL port on the 3DV-EdgeAI-32 device.

  4. Check the adapter connection using the command:

    sudo dmesg | grep tty

    Expected output:

    usb 3-5: ch341-uart converter now attached to ttyUSB0

    where ttyUSB0 is the device name assigned by the system (may be different).

  5. Connect to the serial console using the login and password: admin\admin or linaro\linaro

    Connection parameters:

    • Device — according to the system-assigned name (for the example output above, /dev/ttyUSB0).
    • Baud rate — 115200

    Example command for minicom:

    sudo minicom D /dev/ttyUSB0 -b 115200

Ethernet connection​

Requires an RG-45 cable (patch cord) and a PC equipped with a network card with an RG-45 Ethernet connector.

Connection instructions:

  1. Connect the cable to the Ethernet connectors on the PC and the Ethernet connector on 3DV-EdgeAI-32.

  2. By default, 3DV-EdgeAI-32 is configured with a static IP address of 192.168.0.232. To connect to the device, configure the PC's wired network connection so that it is on the same subnet as 3DV-EdgeAI-32.

    Parameters:

    • IP - 192.168.0.100 (instead of 100, you can use any number in the range 2–254, except 232);
    • Subnet mask - 255.255.255.0 or /24

    Example settings for Ubuntu Linux:

  3. Connect to the device using SSH.

    Parameters used:

    • Port: 22
    • Username and password: admin\admin or linaro\linaro
    • Command example:
    ssh linaro@192.168.0.232

    If you can't find the device at 192.168.0.232, use a network mapping tool such as Nmap ("Network Mapper") to locate the device.

Configuring a network connection​

Log in with the username and password:

  • admin\admin
  • linaro\linaro

To configure the network connection, edit the Netplan configuration file: /etc/netplan/01-netcfg.yaml according to the documentation and your network configuration.

For an example configuration for setting up a local network connection with a static IP address, see IP Address Configuration.

After making changes, apply the new configuration using the command:

sudo netplan apply
