    • Note: Even when configured as a Main Server, it can also function as a Networked Node to acquire sensor data and execute actions.
  4. To use as a Networked Node: Obtain a NODE license. You can configure this Networked Node to send sensor data to a Main Server by registering it with the Main Server. It's also possible to operate this node independently without connecting to a Main Server. Servers not belonging to a Main Server are called Standalone nodes.

4.3 Connection Method

For Wired LAN Connection

  1. Connect a wired LAN cable to the LAN connector of Gravio Hub X64.

  2. Ensure the LAN supports DHCP.

  3. Start Gravio Hub X64.

    • If an IP address is assigned via DHCP, log in to the console:
    • Username: gravio
    • Password: graviohub
  5. Check the IP address using ip addr and access https://[IP_Address] from your browser. (Since HTTPS uses a self-signed certificate, your browser might show a warning. You can proceed to access the page. If you have your own SSL certificate, configure it in the Certificate Settings section on the Gravio Hub Settings screen to avoid this warning.)

For Wireless LAN Connection

  1. Start Gravio Hub X64 (remove the wired LAN cable)
