I just pulled up ActiveHome for the CM11A and it does in fact include the SC546 Chime module (as does ActiveHome Pro for the CM15A).
So that's the way to go to program a SocketRocket: Define a Chime at the housecode/unit address desired for the SocketRocket. Within 30 seconds after powering up the SocketRocket, click the Chime module icon switch three or more times in succession a second or two apart. When the light bulb in the SocketRocket turns On, that signifies that the Socket Rocket has learned the new address.

I don't think the old ActiveHome will allow you to define more than one module at a given housecode/unit address in a given program file - you have to create a separate file for the SocketRocket programming.
