Apex_speed,
Ok. Let's take a sec to get some terminology straight which will help communications. In DirecTV receiver terminology the receivers all start with "H". If they include DVR capability (recording) they append the "R" to the "H" designation, giving you "HR". The number simply refers to the generation number. So the Genies with recording capability are always HRxx units. All receiver only units are "H" designated and have only one tuner. The early DVRs had two tuners and the Genie units (at this point) have 5 tuners. All SWM heads currently in the field typically have an 8 channel unit attached (although there is a 13 channel unit available). You cannot have more tuners than channels for a properly operating unit.
I do count 8 tuners in the configuration you mention, but I am wondering why they configured you with 2 H25s and one H24. Typically they would install 3 H25s or 2 H25s and an HR24 (but, this would have put you over the 8 channels available from the SWM head.) Since you are going to split your setup this would really not be a problem for you.
Yes, you do need to purchase a power inserter for your home setup. You need the 21 volt model like
this one. Since you had the HR54 setup in the RV there is no external power inserter there.
Once you get the power inserter you need to remove the coax from the HR54 Genie currently in your house and put the power inserter on the coax that was attached to the HR54. Put this on the "to SWM" labeled coax connector. Take a short piece of coax and place it on the "to IRD" connector of the power inserter and attach the other end to the receiver you are using in place of the HR54.
Caution: Do not put the power inserter in line with any other receiver in your house unless you understand how to change the hookups to your splitter. There is a specifi power path marked on the splitter unit and you must follow that power path to get power to the SWM head. Your house has been wired for the HR54 position to be the power source in your house.
Important note: You must terminate any coax connection where you remove a receiver with a 75 ohm terminator
like this. You cannot have any open coax lines in a SWM setup. (You can also purchase the units at Home Depot.)
You should be able to turn things on at this point and see reception on all three receivers in the home. There should be no need to change any settings because you are using the same dish that was in place when you added the new power inserter.
Now you can test the Cinema Connection Kit by putting it in line with one of the other receivers. It really does not matter. It will turn your whole coax "network" into an extension of your in-home internet system. I would avoid putting it in line with the power inserter. I don't think these units handle power throughput. If it works, great. If it does not you will probably need to add a recorder ("HR" receiver) to your setup, because the wiring is correct.
Since you do not list any DVRs (other than your Genie) I am not sure if you can access On-Demand (movies, etc) at home. All the On Demand setups I have read about have at least one DVR in the setup since it is not uncommon to need to buffer on-line content.
Now all you need to do is move the Genie, the bridge, and the three minis to your RV. They should work just fine there like they did when you purchased your RV. If it would make you feel better, you could also take the Cinema Connection kit along with you to the RV. But, these were not needed on the HR44 even though DirecTV was telling all their installers to include them in the setup and they are definitely not needed on the HR54. Inserting an Ethernet cable into the back of the HR54 works just fine.
If you find you have an HR24 or H24 at home, by all means DO NOT insert an Ethernet cable in the back of that receiver. There is a plug for one, but there is a design error that shuts down the whole home functionality when you do that. That connector is only applicable if you only have the one HR24 in the house and/or only intend to watch on-demand programs on that receiver. A Cinema Connection kit is mandatory in these setups.
From what you say you should be golden once you get the power inserter and terminators in place.
And yes, you can test the reverse of this setup. But, if the Genie and minis are working now there is no reason they will not work in the RV. Just know that no DirecTV receiver (as of this date) knows specifically what dish it is attached to. They only sense and know what
type of dish they are connected to. So simply moving a receiver from one dish to an exactly similar dish should be totally transparent to the Genie receiver. And since the minis and bridge work fine now they should continue to work fine in the RV.
Oh, and I would not touch any "Whole Home" settings. Your system is working just as it is supposed to do. You should be able to see all the Genie recordings on the H25s. This will only work while they are on the same coax connection in your house.
Hope all this helps.
