    I am interested in adding MRV to my system but I have a few question prior to ordering. I have one HR20-700 and one HR21-700. Each receiver has two coax cables attached to them. My question is..Do I need to add any more coax cable runs to my existing sytem to run MRV? Can I use the existing coax cables? My router is located behind my family room tv connected to the HR21-700. My issue is I had coax cables installed inside my walls when we remodeled so running new cables would be a PIA. Do I need to add any other wiring?

    Thanks,

    Ro

    It sounds like you should be good to go.

    No need to add any more wiring. If you are going with a DirecTV install you will actually end up with an extra coax feed as only one line will be used.

    You will find lots of reading here about SWiM and DECA technology. Both use a single feed of coax to make connectivity between your receivers a snap.

    With only 2 DVRs, you very likely do not have a multiswitch in place meaning each line comes directly from the dish into your DVRs.

    The dish LNB will be replaced with a SWiM version so there will be only one line coming out of the dish. They will put in either a 2-way, 4-way or 8-way splitter and use one line to each receiver (instead of two). It is possible that one of the other lines at one of the locations will be used to send power back to the dish (it needs power to operate).

    A possible configuration in your case:
    Code:
    Sat Dish [COLOR="Red"]<-[/COLOR]+-- [COLOR="Red"]<-[/COLOR]PI -- DECA [COLOR="Red"]<-[/COLOR]PI (-- Terminator)
               |             |
               |             +-- Ethernet to Switch
               |
               +-- DECA ----- Sat In (FTM-2)
               |     |
               |     +-- Ethernet to HR20-700
               |
               |
               +-- DECA ----- Sat In (SWM-2)
               |     |
               |     +-- Ethernet to HR21-700
               |
               |
               +-- Terminated
    This assumes a 4-way splitter is used.

    In that configuration if you were not hooking it up to an internet connection could the 3rd DECA go from the PI to another receiver? Would you need a second PI?

    The SWiM needs a power inserter

    The Broadband DECA needs a power inserter

    If you remove the broadband DECA, you would only need the one SWiM power inserter, the broadband DECA and second power inserter come together.

    You could use the output of the SWiM power to a DECA that is connected to a receiver. The DECA gets it's power from the receiver in this situation and there is no need for that second power inserter.
