The only way that Radio Ra2 can control a garage door is through the contact closure outputs on a VCRX or the LMJ-CCO1-24-B. If the garage door cannot be operated through contact closures then you'll need to check with Liftmaster to see if they have any CCO interface.

I don't know about a P3 motor, but we just installed the car visor control receiver to operate our new LiftMaster 8500 series. It was easy enough to connect it to the Red and first White port. Nice to be able to program a hybrid switch at the front and house/garage doors to be able to operate the garage door!

I am currently working on a RA2 project, I would like to included the VCRX because it is a 3 car garage and there are 3 liftmaster 8500s installed. I was talking to the garage door guy, he said that these models aren't like the older versions and don't work with contact closure. But if you have made it work with that model, I would like to know witch terminals you used. Did you connect in parallel to the button switch? You said the first white port but i guess I'm just looking for confirmation because I'm hearing different stories.
