Before configuring your maps, you will need to register the Controller's IP address at Google Maps and get a key
from Google. Go to

or search for "Google
Map API", to enter the Google code page.
Click on "Sign up for a Google Maps API key".
Click the terms and condition check box and fill in your controller's WAN IP address.
Google will generate an API key for your controller.
