How Do I Incorporate HR34 into Existing Ethernet Whole Home Network?

    The diplexer you've linked, has good rejection, but connecting a BB DECA to it, close to the HR34, would still mean NOT a lot of attenuation between the two DECAs.
    "Signal wise" the internal resistor network of the wireless CCK, with a filter, would be better, since:
    HR34 <--> -10 dB <--> DECA and to filter would mean another -20 dB before coming back to the any DECA.

    Okay. Thanks.

    I guess I'll just swap out the BSF and WDCCK I have at the H25 for now until I get another WDCCK and BSF.

    About the only other way would be:
    add a 2-way splitter with the filter on the input and run the HR34 off one leg and the BB DECA off the other. The splitter will give the attenuation and the filter will do its thing.

    I'm not sure I understand your point on "lag"; how would it manifest itself in this situation? Do you anticipate that streaming shows will need to periodically stop and buffer during playback? The most I can see is a few milliseconds difference in remote trickplay. Not enough to get excited about...

    Middle...
    Considering that most people can only discern time increments on the order of 100 milliseconds (a tenth of a second), it's nothing to be overly concerned about.

    But that's almost 324 nautical miles for radar :lol:

    Ah, there's a missing decimal point there. ;)

    It's been awhile, but not that long. Where's the missing decimal point?

    .00001236 (12.36 microseconds) * 324 (nautical miles) = .00400464 (4 milliseconds)

    Sorry for the silly question, but in this configuration, would the ethernet cable be plugged in to the BB DECA or the HR34? Would it make any difference?

    From what was mentioned earlier in this thread, the DECA would "see" the Ethernet and vice-versa. Is this right?

    I would use the ethernet to the BB DECA and skip connecting it to the HR34.
    "I guess" a powered BB DECA would do what's needed [for the DECA RF] without ethernet being connected.
    Not quite sure what you're second part is. :confused:
    Going with ethernet to your HR34, would have it "see" your network.
    Going with ethernet to the BB DECA, would have the HR34 "see" your home network through DECA and the BB DECA [like your H25 does].

    there would be more load on the interfaces and genrally 100mbit only gets 80-90 each way (it can do better if you have very good efficiant equipment)

    people already complain about lag on long runs (as seen on this forum) so a link thats at 50% load would not be a good thing

    a working network and a well built one are to differant things and as the decas do some qos they'll have even more load processing that data which would in turn cause more lag

    If you want OTA to the HR34 (ie via an AM21) then I'd just put the BSF direct to the reciver and see if it actually causes anything, and see if it heats up at all
    there wouldn't be any benefit to double converting the data so I'd just connect the HR34's ethernet port directly to the ethernet network and see if theres any issue with the BSF, yes it would be hitting the BSF with a low of RF but it seems like it would be more likely to be able to take it than something else.

    or if you're not diplexing on that cable just put the BSF right near the SWM splitter and have alot more cable between it

    My Bad. The second part was actually from a post from the HR34 Anticipation Thread. I knew that I had read it earlier, I was just little confused on where it had been.

    Here's that post...


    Anyhow, I do understand that the network could be "seen" by either connection. I was just wondering if one way was more beneficial than the other.

    That post is in error, but it only affects a DECA network.
    The HR34 can't be the bridge from your home network to the DECA network.
    Only a WDECA/BB DECA can do this.
    In the HR34 RVU setup, only the HR34 needs access to the network/internet, so ethernet on the HR34 works, "but" it doesn't share this to the DECA networked receivers.

    This info was posted by several, but here's a quick reference to a post by Sixto:

    But you didn't answer the question; what is the lag manifested as? In other words, what is the end user seeing that you would categorize as caused by lag?

    Not sure of what version Sixto was referring to, but I did get a PM a day or two back that expressly informed me that MRV clients can't get internet access through the HR34's ethernet port. RVU clients rely on the HR34, so it may "appear" to work for them, but all internet is really on the HR34. What it does do differently is keep the DECA active with the ethernet port being used.

    Not to pick on him, as we've had some PMs over this, "but" I tend to think it's more "theoretical" than "real world", but the truth is not known [yet] as nobody has loaded a network like this to know squat about it.

    "Well", he did say this:

    I just want to understand what problem the "lag" is causing; is it trickplay?
