Confirmation on my proposed SWM / HD-DVR setup

    Hey guys, I know there are some knowledgeable installers on this board, and I am unfortunately "stuck" in an MDU configuration where the builder cut corners.

    Issue is that the builder ran only two wires from the central dish to each unit, and we have two TVs in separate rooms of the house. For now this means that, since I have HD DVRs (HR20 and HR22), I get only single tuner capability on each TV.

    For "my" (really the whole family) Christmas present I want to spend the $$ on an SWM and necessary stuff to get everything working w/ dual tuner capability in my unit.
    The installer for the building has stated they will install an SWM for only me (for a fee) and are willing to sell it to me as well. Obviously I can find them cheaper elsewhere so am going to be obtaining an SWM8 for this purpose.

    My question is, once the SWM 8 is installed and the two lines to my unit are running from it, can I use the SPLIT2-Z splitter to get usage from both tuners of both receivers in my unit? Or will i not require a splitter at all? What about for DTV's new "doubleplay" (or whatever) feature?

    Thanks in advance
    B

    You will not need any splitters at the receivers themselves. You just hookup SAT 1 (SWM) and leave SAT 2 disconnected. Doubleplay will work fine as well as both tuners will be active even though you only have one SWM coax running to each DVR.

    If they hookup both coax lines to the SWM outside of your unit, just run one line to each DVR, such as this diagram:
    http://www.swm8.com/2DVR-SWM12-0SPLIT.pdf

    If they only hookup the SWM to one of the lines coming into your unit, then you would use a 2 way splitter to split the single coax coming in to each of your DVRs such as this diagram:

    You need 4 input lines from the master dish to a swm8. Each line from the SWM8 would them control BOTH tuners in each of your DVRs with one line.

    great, thanks
    can somebody else confirm this? in a previous discussion of doubleplay, i thought i read that it required two actual tuners to function

    There are two actual tuners. It's just that with the SWM installation only ONE cable is needed to the DVR.

    I can 100% positively absolutely confirm it for you. I run the same setup in my house and have installed them as well :)

    The SWM is two actual tuners through one coax. Internally the receiver uses the one input as two tuners even though the conventional SAT 2 connection remains disconnected outside the box.

    SWM == Single Wire Multiswitch .. Both tuners will work from the single coax so you will get the benefits.

    It sounds like the MDU installers know what to do, just make sure they don't let anyone else mooch off of your SWM-8 .. You will already be using 4 of the 8 channels, but you should be able to add up to four more tuners in your house if you choose since the SWM is yours.

    Oh, and you should be able to put the power inserter in your home to power the SWM. Just make sure everything gets plugged in correctly.

    right, they've assured me that basically they will install and uninstall it for me if/when i sell the place. I plan on writing on it in permanent marker my name and address and that it is to be used only to service my unit
    i'm not sure how this would be done. as i understand it the power inserter runs to the SWM via a coax cable. to power it w/in my unit i'd need that coax cable run to my unit, which isn't done. how would i put the power inserter in my unit?

    You put the PI on the coax that is coming in to feed your receivers.

    If you check this diagram (Thanks litzdog911), you'll see that the power inserter connects to one port on the SWM-8. Whichever coax from your home goes back to the power port will connect to the inserter and the other end of the inserter will go out toward the receivers. The second line can connect to the other port on your SWM. This diagram does a good job of showing where things are. The two 'IRD' ports on the SWM are essentially the two cables from SWM to your home. All of the gear (including inserter) can be in your home.

    Doug, a several questions on your diagram as I prepare for DECA.

    I have a Zinwell WB616 MS now. I assume I can just drop in the SWM8 where the Zinwell is? That is, the outputs from my current slim dish correspond to the inputs on the SWM8?

    Second, why are there multiple 2-way splitters from IRD1? Aren't there 4-way splitters that can be used?

    Thirdly, I currently power 16 tuners with my Zinwell. Some of there are hooked up to legacy receivers. Can I hook up an HR10-250 (just used for SD) to one of the IRD output or do I have to use one of the other outputs?

    Finally, is there any difference between the IRD1 and IRD2 output? That is, I assume you could have hooked up any DVR to any output?

    Does the 8 include the legacy outputs?

    I have 5 HD DVRs (10 tuners), 1 HD receiver and 2 legacy DVRs (2 tuners). Sounds like I would need 2 SWM8s?

    Thanks for the detailed reply.

    8 SWM tuners + 3 legacy tuners = 11

    Another possibility that wsn't mentioned: feed the 4 SWM8 inputs with 4 of the output lines from the WB616. That leaves you 12 remaining legacy outputs to feed older devices. This setup works great, I have it in my house. I made some little 6 inch coax lines to connect the two boxes.

    The WB616 is/was a great switch, way way better than the el cheapo non-powered WB68. Too bad they've been discontinued. But since you have one already, why not use it?

    Which 4 outputs from the WB616 would I use to feed the SWM8? I like this idea since I do not want to have to buy 2 SWM8s.

    Any 4 outputs on the wb616 would work. If you wanted to you could even split the inputs to the wb616 and swm8 and hook them up in parallel. If you split them you need to make sure the inputs match on the WB616 and SWM8 but running the SWM8 off the WB616 you don't need to worry as any port will provide what the SWM8 needs.
