adding a 311 to existing setup

[Ascratch]

I would like to add a 311 receiver to my setup. Background info: originally I had an 811 HD receiver and a 311 in two different rooms. I then upgraded to a 622 and removed the 311 with the thinking I would use the dual tuner option of the 622 to reach the room where I had the 311. Unfortunately, the extra cable that was needed to reach the second tv was too diifficult to do and unsitely outside the house to make it a viable option. So my real question is since the orignal set up was with a 311 in the room in question can I simply purchase a 311 now and hook it up or would the cabling that was done to make the 622 work affect what I can do now? Also, what am I looking at as far as extra charges because I am adding a receiver?

Thanks for any input.

verify the cable to the room in question is still connected to the dish/switch.
