I just gave my SA tivo to my brother. He wants to hook up his cable and his DTV receiver. Unfortunately his receiver has a different data port than mine did. I had the standard 9-pin port that the serial cable plugged directly into. He has a wide port on his receiver.

I know that the tivo came with one of these adapters but I must have thrown it out. Can someone tell me how I can go about getting one for him? Are they available at radio shack?
