As Davwol mentioned above you will have to change some settings on the 2630 to get it to recognize the Raven, also some settings may need to be changed in the 450 to send signals to the 2630.  In your equipment tab on GS3 make sure you enter in correct measurements for globe height, hitch control point, and distances the boom is back from the globe or control point, it has a guide to walk you through this.  Other than this you will need to set up an operation, farm and field in the resources tab, and if connected right it should show coverage for you when you turn the master on and off.
