Open Xilica Designer.
Click Settings > Preferences located at the top left of the software.
In the General tab, check Skip Dante Configuration. This will allow you to use Audinate's Dante Controller to configure Dante connections. Click "Done" to save the settings and reboot Xilica Designer.
Another way to do this is when Going online, a Load Design to Devices box will appear to select your devices. On the right side of the box is an option to "Skip Dante Configuration".
