I am installing a iPronto and a RadioRA lighting system.

From my understanding (PLEASE correct me if I am wrong) The radio RA uses RF to control the lighting system. The pronto uses IR, and RF to go to the wireless communicator then converts them back to IR.
1. How can I make this connection between the two?
2. I currently have the iPronto and radioRA, what else do I need?
3. Where can I get the IR codes for the RadioRA?
