Since I tend to be the resident DirecTV expert here, I would like to share a couple of things:
Current Promo for Free equipment to a new account is:
1 Genie [5tuners] (current model = HR44 last years # = HR34) + 3 clients [wired or wireless are totally free but DTV charges the customer $100 for the video bridge that make the wireless units work]
OR 4 HD boxes [H-24 or H-25]
* HD DVRs [2 tuners] are not offered for free to any customer getting more than 1 rec'r; IE 1 TV. These are offered free to a 1 TV household.
If you make a 5th TV an HR24 (HD-DVR with 2 tuners), it will marry up with the Genie so that hitting the "List" button displays a combined list of recordings on both units.
According to the training class I attended and given by the DTV engineering dept, the video bridge for the wireless clients uses a frequency around 450Mhz.
The IR coding on all models for last 10 years is all the same. The latest models are more responsive to IR signals
All the HD units that are capable of working in IR or RF can only be in one or the other; not both. EXCEPT FOR THE GENIE MODELS [#HR34 & HR44] WHICH ARE CAPABLE OF DOING RF & IR AT SAME TIME. THESE MODELS WILL STILL WORK WITH THE OLDER STYLE WHITE IR REMOTES BUT NOT THE OLDER STYLE WHITE RF REMOTES. For RF you must use the newer style RC71 remotes which many customers don't like as much as the white ones.
IP control still works when using RF but I am not familiar with controlling by RS232. We have customers using RF remotes and the DTV IPAD AP at same time which works via IP.
Deca/Moca modules do not take up a tuner space(count) in a swim system. These are device that mixed IP & RF over co-ax
H-25 will only work in a swim system. Where as H-24 will work with a 6x8 switch or in a swim system but will need a B-band converter if used with a switch. We use these mostly with older in service systems that have not been installed with swim. PLEASE note H-24s tend to over heat more often in a closed cabinet than H-24. All new installs are supposed to be done with swim.
FINALLY - Have the customer contact a local dealer in your area! A good local dealer can cater to you and your customer a lot better than corporate 800 #s or .com contacts. Whether customer is new account or already has DirecTV they can set up their order and see what they promos qualify for. Its tough to find on DTVs web site but "Find a retailer" is buried in the bottom right corner of DTV.com (abbreviated).Try this:
