DECAs with non-receiver devices?

    So, I'm building a desktop PC as a media and gaming machine for my bedroom. After doing some reading, I decided that I'd use a DECA II adapter (obtained from Ebay for $10) instead of running an ethernet cable from my living room to my bedroom. In my bedroom, I've got an H25 IRD, so I'll need a green-label splitter for sure, but I was wondering what the best way of wiring this would be. I've already got a wired CCK set up in my living room, so I have a general idea of how to do this, but I figure you guys will know better than I will about the more in-depth aspects of it. A diagram would actually be greatly appreciated. Also, to anybody who has done this, what sort of results should I expect out of this in the way of speed and latency? I'd like to use this as a gaming setup, but if that's not possible with this, I'll just use an 802.11n card.

    You'll need a power supply for the DECA but all you need do is plug the Ethernet cable from the DECA into the PC. I'm doing this to supply a hard wired connection to a Roku XS. It works great, and provides a far better connection than any wireless connection.

    Just split the coax (hopefully you don't have a lot of splitters and cable runs between the bedroom and the SWiM) and run a coax from the splitter to the DECA input (the other end will connect to the power supply).

    Here is a link to a power supply on Amazon: http://www.amazon.com/POWER-SUPPLY-PS18DER0-03-NETWORKING-DIRECTV/dp/B003ZMH6DO

    Do you have any speed or latency numbers? I was hoping to get a general idea for how much lag this'll introduce into my setup, though I can't imagine it'd be slower than wireless-n.

    My setup runs SWMLine-5 to 8-way split to H25, with about 20 feet of coax from splitter to my room, and another 20 feet or so to the SWM. The DECA/CCK in the living room is about 50 feet away from the SWM. My house isn't particularly big.

    I don't know if it's different internally or not. But this is not the power supply that comes with the DECA II. See here for an ebay auction for a DECA II with the power supply. It has a Buy it now price of $11.99

    For when that link expires, here is the same kit at Solid Signal

    As I said earlier, I don't know whether the power supply for the DECA I works properly with the DECA II or not. But, since buying the full kit at ebay is less expensive than the power supply at Amazon (even with S&H), it's probably a good idea to go the ebay route.

    I've already bought a DECA, not even thinking about the fact that it'd need a power adapter. Is there a way I can get the power adapter separate? Think anybody here would have one I could get from them? I think the higher-ups would probably frown upon me taking one from work, you know?

    UPDATE: So I've bought the splitter and RG6, the DECA, and the parts for the computer. Hopefully, by Saturday, I'll have a whole setup ready.

    The DECA adapters use the MoCA 1.1 protocol standard for data communication. The official numbers between nodes at least of which are;

    Max. data throughput Greater than 140 mbps for a 6 node or larger cloud. Greater than 176 mbps for a two node cloud.

    Latency is less than 4.5 ms on average with less than 7.5 ms 99.9% of the time.

    Max. packet loss is less than 1 per 100,000.

    As stated these are only the official specifications, YMMV though in the real world.

    If you are talking about Internet gaming (as opposed to LAN party) your Internet latency will by a minimum of 10 times what the DECA introduces. Assuming no major problems exist in the network components, you'll get better than fast Ethernet throughput.


    You should be okay...everything is green label right?

    I don't believe it's available separately from retailers. Maybe someone on ebay has one for sale. However, given the price for the kit on ebay, I would just buy the kit and save the spare DECA II in case I ever need it.

    Everything is green label, and I am talking about Internet gaming. The way you describe it, it sounds like I'll have a great connection, no problems at all.

    I bought the kit on ebay as you suggested, from the link provided. It'll be nice to have a spare on hand instead of having to deal with DirecTV for it.

    Also, DHCP just passes through, right? Nothing is modified between the DECAs?

    Correct;

    The DECA adapters are ethernet bridges using MOCA 1.1 on the coax interface which operates at OSI levels 1 and 2 ("physical" and "data link").

    DHCP is at a higher level 3 (or "network") protocol which the DECA nodes are transparent to.

    Hey, I remember these terms from my CCNA class! xD
    But in all seriousness, that's for the best. I can't stand when I use a router in bridge mode and it wants to use its own DHCP and makes my room transparent to the outside world.

    Just an update:
    I got the DECA that I ordered in the mail yesterday. I pulled out the crappy wifi dongle I had (Never buy Belkin WiFi anything. Absolutely terrible.) and put the DECA in right away, just pulled the plugs straight out of my H25 and hooked it up to my computer. Right out of the box, everything just worked. I'm getting 20+ Mbps down, 10Mbps up, and 40ms pings. So, I'm really liking it a lot, and once I get my splitter and coax, I should be back in business as far as TV and my PC. In case it wasn't painfully obvious, I am pretty excited about the whole mess. :)

    I would not have thought of this but it worked well for me also. Does anyone have any thoughts on how this might effect whole home performance?

    It basically doesn't, unless you are pumping tons of data through it.
    I use this in two rooms to hook up the TV's, DVD's etc to a wired connection...
