Update (2/8/2011): Since DECAs, Broadband DECAs, BS Filters and splitters are readily available cheap on eBay, and installers finally understand how to install WHDS, I really don't see a need to use this configuration any more. :nono2:
I don't use it, and don't recommend that you use it. However, it does work.
If you're adventurous and one of your CAT5-attached receivers is near your router or a switch with an extra connection, put the DECA in line with the receiver coax connection (which simultaneously powers the DECA and is a Band Stop filter), then
plug the Ethernet cable from the DECA into the router/switch (
leave the receiver connected to the router/switch).
Voilla! Internet connection with no additional splitter, power supply or Band Stop filter. Yes, I've done this, it works, but as always, YMMV. Note that the bridge will go down briefly when the receiver reboots.
Warning! Warning! Danger, Will Robinson!
This configuration is
not supported by D*, some folks will tell you it won't work, and it will quite possibly cause a rift in the space-time continuum and destroy the universe.
The single DECA is certainly a
100Mbps bottleneck to the 175Mbps DECA cloud that would not exist if there were one DECA to the DVR and another DECA to the Home Network. A quick worst-case engineering analysis shows that you
may saturate this bandwidth
if the DVR is streaming to a receiver in the DECA cloud and you have a dozen or so DVRs* in the DECA cloud streaming video from the Home Network.
* would exceed a SWiM-16 capacity by 11 tuners, unless most DVRs were limited to a single tuner.
