From Mobitouch cube

Before a newly purchased unit (or a unit which has been previously deregistered) can be used in the Mobitouch CUBE system, the Node must be activated. Registration is a process which assigns a Node as belonging to a particular Company.

Node registration process

• From the Menu Bar choose Node->activate a new node
• Insert the activation key you've received (it is included in the WLP-500 box)
• Click the "activate" button.

From now on the node will be registered and will appear in the Node Manager window.
