    The "rough" drawings show two wiring options. Option 1 is the way installer completed and seems to be working. Option 2 is recommended install by Kevin Ryan from dbstalk.com and a video he posted on youtube. Here is the link.

    My question is which option is recommended? Thanks.

    Option 1 is not connected to the red port, so nothing will happen. :)

    If connected properly, I would do option 1 just because I don't like everything passing through the PI.

    Concerning the first image...on the left.

    The PI output needs to go to the "DC Pass" input, the red one, on the splitter...the farthest right.

    Thanks both for your input. You are correct, I did not draw the diagram accurately. Have made revisions. Please review and comment again. Thanks.

    Option 2 is correct. :) Do you have a SWMLine dish?

    Also - is that your actual splitter model or just a generic image?

    Either will work.

    Is Option 1 any less valid than Option 2? Option 2 kind of defeats the purpose of having a splitter with a power passing leg.

    I setup my SWM-8 using Option 1 somewhat arbitrarily because I didn't have room in my wiring box for the PI.

    Yes, I have an SL3S. The splitter in photo looks identical what I have. The photo is Model 4RO-03 mine is a 4RO-01. If I understand, both connections will work? Is one better than the other? Just to restate, the installer has it wired as in option 1. It would be very easy for me to rewire to option 2.

    Either will work with no performance difference, but option 1 needs a termination on the unused port of the PI.

    ...or a receiver/DVR.

    Generally, Power Pass only becomes critical in situations where you need to send a cable to a receiver that is in front of the PI. If all of your receivers are after the PI, which was the OP's case, the importance of Power Pass becomes a non-issue.

    Thanks all for your help. I will leave it the way it is wired. Yes, there is a terminator installed on the unused PI connector bob.

    Look again...the OPs current install is option 1, with all IRDs "in front of" the PI. So, use of the the power pass port, on the PI leg, is needed.

    I see a thread every once in a while where there are issues and then someone moves the PI to another room and things clear up. That makes me suspect that sometimes PIs can be finicky about passing signal through them. You do drop a little voltage going through the splitter like that though, so it's give or take IMHO.

    That said, I have MRV data running through mine with no issues.

    Kansas, then is it your opinion I should be using option 2? I was hoping I was done with this issue.

    I'd call you "done" now.
    I've got receivers in front of my PI and behind my PI and everything works.
    From reading your posts, you should be fine.

    That's not what I see in the Option 2 revised diagram. Either way, as VOS points out, he's done. Is it working properly? Done.

    Correct. I was ONLY referring to option 1.

    The OP asked if it was OK (and it is, of course)...or if he needed to try option 2.

    His first option 1 image (that was removed...and replaced by the OP) had the feed from the PI into a non-DC passing port of the splitter. After a question was raised...he then replaced it with the option 1 image you see now.

    Sorry for the confusion.
