    Folks,

    Please review the attached installation instructions. This should provide you with much more information than you already have (including pictures).

    As for the name DECA ..

    DIRECTV Ethernet to Coax Adapter

    Cheers

    Wow, this is a good doc, it's going to take a little time to read thru this.

    Thanks!

    This is interesting.....

    connecting the DECA’s Ethernet port to the STB’s Ethernet port using the
    supplied 12 inch CAT5 cable. If the STB has two Ethernet ports, always
    use the top port for networking. Ensure there is nothing connected to the
    bottom Ethernet port, if it exists.
    MAKE SURE YOU DISCONNECT ANY HOME NETWORK ETHERNET
    CABLES FROM THE SECOND JACK OF YOUR STB. Failure to do this
    may result in network loops (from STB -> DECA network -> Router back to
    STB via Ethernet) that will take down your network!

    So... it sounds like we can't use the 2nd poet as a pass thru anymore.

    Also, I thought the bottom port was the active port?

    Question if we're using a SWM8 vs. a SWMLNB. There's the one line in the doc about the SWiM filter being installed between the SWM and the 1st splitter. Does this mean that all STB's that we're testing this on needs to be off the same SWM output on the SWM8 vs. having the STB's split between the two SWM ports?

    Looking good. Will FedEx require someone at the house to sign?

    No, the filter needs to be installed between the Router dongle and the SWM.

    I don't get that from reading the doc, there's no mention of having the SWiM filter at the router connection, just at the 1st splitter.

    The way I understood it is that the filter needs to be install after the router dongle connection and before the first splitter.

    Or did I misunderstand it?

    "The SWiM Filter included in your kit must be installed somewhere between the
    SWiM unit (either standalone or SWM-LNB) and the first splitter in the network."

    Don't see a requirement for having it at the router dongle.

    Yeah, your right, I just re-read it. My bad.

    seems fairly straight forward.

    from the SWM, before the first splitter, install the filter.

    at each receiver install a DECA.

    at one of the receivers that already has a network connection install the DECA PI and the DECA for network access.

    seems like all of the DECA's must be on only one of the SWM ports.

    No, you may not break open your SWM8 units to install the filter. :) So you'll have to do all SWMing off a single port.

    with MOCA being in the 500-600MHz range, looks like OTA is not available (fine here - don't have it).

    I wonder if next is to expand the range for more SWM channels.

    Usually a person is not required. I haven't yet.

    Well, I am running 2 HR's off of SWM1 and the H23 off SWM2. Looks like I've got a problem! also, my STB's are all networked via wireless as I don't have any ethernet to these locations. My internet comes into my office to my cable modem to my wireless router to the rest of the network via wireless.
    In my office, that internet coming in is the only coax and no ethernet.

    I was planning on adding a splitter off the splitter that feeds the HR's and run my internet into one of those legs to hopefully backfeed the local network traffic. Any ideas?

    With 500-600Mhz for DECA, you could put 4 more SWM channels starting at 668, 770, 872, and 974. Other 8 could stay where they are at 1076 and up.

    Just speculating.

    Remember, the satellite tuners in the current HR2x might not go down that far except in the HR23. That could be a problem for SWM.

    Cheers,

    Choctaw, OK
    I'm still wondering if I can use this DECA as a bridge to a switch, or, does it need to be dedicated to a STB?

    Looks like I've got some hoops to jump through as three of my SWM lines also carry OTA, and no SWM cable in the vicinity of the router.

    Is there any limit on the length of the Ethernet cable connecting to a DECA?

    Make sure to note number 5 from the instructions...

    This is something you guys may want to take some time this weekend to write down... That way you can compare once you get everything installed... :)

    ? One of the DECAs has a power supply specifically to connect a switch to the SWM Network.
    Yes. 100M. :)

    (Standard Ethernet rules apply.)

    And I noted the instructions show one can use the switch inside the HR21+s to connect both networks together! :)
