This is more of a testimonial on the great people and knowledge that is available on the forums. Case in point:
My bride and I decide to switch back to DirecTV from cable so we would have additional TV programing available on our planned trips. We knew it worked as the previous owner had DirecTV in it.
On Jan 2, 2015, the DirecTV tech installed the new boxes in our stick home. We went with the D12 standard def boxes. Asked him what I needed to do to make the box work with the KVH SF antenna on the Motor Home. Said just change it to 18 round dish in the satellite setup. Sounded easy enough but wasn't because of my lack of knowledge on the box and dishs.
Highlights of my install:
First, when I connected the box to the KVH and the TV, it sat forever on the searching for satellite page. Thought I tried every button on the remote to make it go away but couldn't bypass and had to wait for it to time out. After a couple of rounds of this, I went on iRV2 and did a search to discover I just needed to hit the Exit button. Duh! Guess I didn't press that one afterall.
Second, I couldn't select the satellite dish that I wanted as it was greyed out. So once again I checked iRV2 and found out I needed to select the multiswitch option first. Ah, forward progress again.
Third, the 18" option didn't seem to work. Back to iRV2 and KVH to find the recommended dish config is the 3-LNB 18 x 20 which is option #2. More progress.
Fourth, after many select satellite switch button pushes, I finally got to the correct satellite. However, I was getting a tuner error. The page showed the satellites and the even/odd had a red X in one box and the other boxes had a green check mark. Messed with it for what seemed like hours. Couldn't get all green check marks so back once more to iRV2 and found this thread
that was the exact problem I was having. Gee, all I had to do was click on continue and ignore the error message. Finally, success!
Hope this helps someone else that is just learning how to install your home DirecTV box in your motor home.
Happy New Year!
