NXT Mercury-Powered (MSC) controllers are typically added to the system using the Scan feature. However, there are some rare situations where the controller will have already been programmed with its IP address and simply needs to be manually added.
Note: To manually add an NXT-MSC controller you will need to know the controller's programmed IP address.
The following section explains how to add NXT-MSC controllers via the Scan feature. The Scan feature polls the network and MSC gateway and automatically returns a list of all detected NXT-MSC controllers it finds.
