If the IP of your device changes (for example, if you unplug it and it is assigned a different IP when you plug it back in), you will need to tell the build system to target a different IP.

To change the targeted IP:

In NBEclipse, click on "Project" from the top menu, then click "Properties".
In the left-hand panel of the Properties menu, click "NetBurner Options".
Change the targeted IP address in the right-hand side of the panel.
