    As long as you have the PI hooked up properly (Red to the SWM and White to the IRD) otherwise you will fry your IRD.

    I installed my PI outside, but inside a weather proof electrical box along with an 8 way splitter. Should I think about moving it inside the house? I live in Orlando with a temp range of 25F to 100F[/QUOTE]

    Having lived in Orlando years ago I'd be more concerned about moisture getting to the PI than the temperature. If you're convinced it won't get wet or even really damp then I guess you're OK. Personally I would move it inside but I can't see your installation and how well the PI is protected.

    Is there a recommended power disconnect/connect sequence when making changes to an SWM setup? We are going to be adding another HR22-100 soon and, as a result, need to replace our 2-way splitter with a 4-way. This is my thinking:

    power off DVRs
    disconnect DVRs from wall power outlet
    disconnect PI from wall power outlet
    remove/replace splitter
    connect PI to wall power outlet
    connect DVRs to wall power outlet
    power on DVRs

    Is this correct? Anything new/unusual I should expect to see on the DVRs during the boot up process?

    That certainly will work and is probably the "textbook" way of doing it but I'm not convinced all of that is necessary. I'm into three months with my SWM-8 setup and just the last couple of days we've gotten hit with a series of storms that have knocked the power down from a few minutes to four hours. Every time everything has come back up without a problem. I even made a "mistake" a couple of days ago when I was installing a new power conditioner and unplugged the PI while the receivers were up and running. I figured "oops" and I'd have to reset all the receivers. Nope, they came back on line immediately without me getting things back in sequence. If I were you I'd just install the splitter and then bring the new DVR on line for it to recognize the SWM and leave the rest alone. I think that'll work and be a lot less of a hassle. Worse case is you go back and do it the "textbook" way.

    I guess it would depend on where the splitter is.
    If it is after the PI, then I wouldn't power down the SWM and might not even power down the receivers [but I would be careful to not short out any coax].
    On the other hand: If the splitter was between the PI and the SWM, I would definitely power down the SWM.
    Once the SWM was up, if a receiver didn't come online, then I'd restart it.

    I too have lost power and had the system come back online without needing to do anything.

    I didn't think about where the PI might be but that's probably a good point. In my case the PI is after the splitter between IRD#1. Since my SWM-8 is in an attic it was the only way I could power the PI without putting in an outlet.

    I am contemplating having a house wired or wiring it myself for 2hddvrs and 2hd rec., and 1 egacy receiver. My concerns are that the house now has DTV in two rooms and will be adding three more,currently older dual lnb dish and 2 legacy recevers, 3 walls to fish,200 ft of new wire to pull, new dish to mount. I have call Dtv and their response was the installer will let you know the price after the work is done. Paying thebill isn't the problem but an upfront estimate would be nice to see if I would rather crawl around in the attic myself. Any help or info woould be appreciated.

    This really shouldn't be posted in the SWM sticky thread, but a quick answer. The installer could charge anywhere from $50 to $100 per wall fish depending on the difficulty and time it takes. Many installers won't even do the work, as they are not scheduled to permit taking that much time. If you have the ability to do the work, I would suggest doing it yourself. If not, perhaps hire an independent resource to do the work before the installer shows up. Use solid copper core RG6 coax, and leave plenty of slack at the dish/multiswitch end.

    To get straight to the point, does anyone have a recommendation for an 8 way splitter (I'd prefer a power passing unit)?

    The long explanation is that currently I have the 5LNB Slimline dish at my 2 story house. We only have an HR22 right now, but I'm finishing the basement, and will want to move that to the basement and put an HD receiver (or HD DVR) in the living room, and maybe down the road something for our bedroom (2nd floor). Since I want to simplify things as much as possible, I'm thinking about buying the SWM Line LNB, then pull a new single line from the dish to where the existing cable service's wiring is split. There I'd drop in the new splitter so I can use the 5 existing drops plus my 3 new basement drops. Solidsignal has an Eagle Aspen, or the SWS-8, both of which fit the bill (and I could order everything from one place), but I was just curious if anyone had opinions one way or the other.

    Do keep in mind that SWM8 supports 8 tuners. If you wire to 8 locations, and have one or more DVRs, you can't have all 8 locations live at the same time. A DVR uses 2 of the SWM channels. If you have 2 DVRs you have used 4 of the 8 SWM channels, but only 2 of the 8 splitter ports. With four DVRs, you will have used all of the SWM channels but only 4 of the splitter ports. So you are now left with 4 splitter ports that you can't use for anything. Plan your installation accordingly.

    To take this a step further:
    All unused ports should be terminated.
    If you end up with 4 DVRs, then the 4 terminations on the 8-way splitter will mean each DVR is getting only half the power it could if you were to use a 4-way splitter and no terminations.
    If you have a mix of receivers & recorders that need more than four lines, then using a 2-way splitter [off the 4-way] will only drop the power to these feeds, which should/can be the shorter cable runs, leaving the higher power for the longer runs.

    Dave29 I hope you monitor this thread.

    I need to disconnect the SWM but I don't remember how I installed it so I don't know how to disconnect it. Its been about a year. I bumped the dish lightly (its on the ground) and now I cannot receive HD channels, only non-hd.

    This is my set-up: I have the big old HD dish and only one cable going from it to the living room where the only TV and receiver are. The power inserter is at the receiver.
    The SWM is at the dish. There are four cables from the dish into the SWM and my one cable leaving the SWM in the power position.

    I know I have to remove the power inserter at the receiver.

    What I don't know is how my single cable gets connected back to the dish. It seems to me I had to open something at the dish to find the four cables that I hooked up to the SWM when I got it, but I can't remember any details.

    You and I and some other posters discussed this on the SWM thread at the time, but that thread has been removed. I kept it on my favorties list so I could refer to it, but it is no longer available.

    I assume if I remove the SWM and return my single cable back directly to the dish I can receive HD channels but I will only be able to record one channel at a time, although I can watch a recorded program while recording something else.

    Please help me remove the SWM until I can get someone out here to look at my dish.

    Thank you.

    After two successive DTV tech visits that failed to bring the correct hardware (either a powered WB616 multiswitch or a SWM-8 unit) to deal with my long cable runs , I decided to take matters in my own hands:

    I installed a SWM-8 single wire multiswitch in the basement of the house, along with a PI-29 (29 volt power inserter), also located in the basement of the house, with 4 buried 140 foot runs of RG-6 cable connecting the SWM-8 to the external Slimline-5 antenna. This placed both the PI-29 and the SWM-8 module about in the center of my cabling installation. All of the recent problems with my HR21-700 HD DVR were corrected immediately by the SWM-8, despite the DTV's tech. escalation desk's warnings that the SWM-8 would be less tolerant of long RG-6 cable lengths and connected to some longish runs of RG-59 cable inside the house walls.

    Despite DTV's verbal warnings, just the opposite cable sensitivity situation is true, because the SWM-8 requires less signal bandwidth (slightly less than 2 GHZ), as compared to the 2.4 GHZ signal bandwidth required by either the WB68 or WB616 multiswitches. While I suspect the use of a powered WB616 might have also solved my performance problems with long cable runs, I am very happy with my SWM-8 results.

    When the weather is a little warmer in these parts, I may re-locate the SWM-8 module to the dish area and leave the Power Inserter inside, but this doesn't really have much benefit to me, as I would still have to drive three D11 receivers from three dedicated 140 foot RG-6 cables that connect to the SWM-8's legacy ports. In this situation, the fourth 140 foot RG-6 cable would be used drive two HD-DVRs and an SD-DVR via a basement-mounted splitter.

    Bottom line: If you have some long RG-6 cable runs (say 250 feet or more) or some hybrid RG-6/RG-59 cable runs (250 feet or more in total), give the SWM-8 a try. It certainly worked well for me after my HR21-700 stopped working reliably on certain HD signals after about 10 months of working just fine. Don't listen to the "advanced" techs (and I talked to several installation supervisors at Ironwood who said this) who will tell you that your installation simply cannot work for HD because you have some interior RG-59 cable runs. RG-59 doesn't help the situation if you have a borderline/big installation, but give the SWM-8 a try. Using a SWM LNB at the antenna may have successful results, too, since it is also less demanding of the interconnecting coaxial cables.

    I have the same problem today. I get no HD channels only non-HD, message looking for sat 771. How did you resolve the problem?

    Remove the PI and use one of the four cables from the dish to the SWM and connect it straight to the one cable going to your living room. You can get/use a "barrel" [which is a simple connector to connect two cables together]. Bypassing the SWM "should be all you need to do". "Bumping the dish back in alignment" would be needed for your HD, along with connecting the BBC to the input of the receiver.

    VeryOld School -

    Are you saying that the problem is with the alignment? If that is the case, then would I not have to disconnect the SWM?

    The reason I was going to disconnect it was because like "aleicgrant" above post, I get a message not receiving sat 771. I cannot receive HD channels, only non-HD.

    Are you joking about "bumping the dish back into alignment"? I mean I will have to get someone out here to align it, I don't know how.

    The HD [Ka] beams are narrower than the SD [Ku] so it seems that when you "bumped it", you knocked it out of alignment. If it's something you can't do yourself [by having someone watch the signal level screen, while turning the fine adjusters on the dish], then I'd have a service call setup to have your dish tweaked back in alignment.
