What alternative connection method can be used to configure a controller’s IP address if a network is unavailable?

The USB connection is an alternative method that allows users to configure a controller’s IP address when a network is unavailable. By connecting the controller directly to a computer or a terminal via USB, users can access the controller’s configuration interface and make necessary changes to network settings, including the IP address. This method is often favored for its simplicity and the ability to provide a direct, high-speed connection without needing a network infrastructure.

Other methods, such as wireless or Bluetooth connections, generally rely on the existence of some network infrastructure or wireless signal to facilitate communication. In the absence of a network, these methods may not be suitable for configuring IP settings. Serial connections can also be a viable option; however, USB connections are typically more user-friendly and prevalent in modern devices, making them a more common choice for direct configuration tasks.
