This document provides instructions for installing Eding CNC software and setting up the Ethernet interface to connect to a CNC controller. The installation process involves downloading the software, running the installer, selecting installation options such as language and location, and installing USB drivers. Key settings configured during installation include running the software as administrator and disabling Windows updates. The Ethernet interface is configured by assigning static IP addresses to the PC and controller, with the controller typically set to 172.22.2.100 and PC to 172.22.2.101. Communication can then be tested using the ping command.
