When connecting to the Commander to load the application, the Ethernet cable is connected to which port?

The Ethernet cable must be connected to the "N" port when loading the application onto the Commander. The "N" port typically stands for Network, indicating that it is designated for network connectivity, which is essential for communication between the Commander device and the server or other network resources needed for the application loading process.

Other ports like "A", "A1", and "A2" may serve different purposes, such as serial communication or alternative connectivity options, but they are not intended for standard Ethernet connections necessary for application updates or loading. Thus, the "N" port is crucial for establishing the correct network connection needed during this process.
