 I Love powerline. I cannot emphasize that enough. This is the link sis PLS K 400 this is a powerline kit that not only communicates, but also acts as a Well yeah, okay So this is a 200 megabit per second powerline kit which is adequate for you know Probably a single HD stream and then some additional you know surfing traffic and whatnot So what's most interesting about this particular kit is what you're going to see on the bottoms of on the bottom of one of the adapters So we've got the one adapter here. This is a pretty normal looking powerline adapter What I do like about it is that it plugs directly into the wall some of them are more for positioning away from the wall and While that's good from a heat dissipation perspective. It's not necessarily great from a convenience and Sightliness, I don't know. I don't know if sightly is something you can say you can say unsightly, but yeah, I'm not really sure Sorry from that perspective Yeah, so it plugs in directly into the wall. Okay, you've got your Standby reset button right here on the other side You've got your link button so you can get it to communicate and link up with everything All the other power line devices in your house that are compatible. We've got one network port here We've got ventilation holes looks like a standard power line adapter now look at this one. Aha This one's actually a little bit bigger. Oh look at that. It's significantly bigger Okay, we've got all of our indicators here including the computer activity LED the home activity LED as well as the power LED same buttons except on the side this time instead of one of them being on the bottom and on the bottom ha ha One two three four, so what is this good for what is special about the PLS K 400? What's special about it is you take this guy you plug it in next to your router you plug your router into it now your Power lines in your house are networking enabled and then you take this guy and you put it somewhere where you have a whole bunch of devices So what this does is this these are all 10 100 ports and it acts as a as a switch So what that means is if you throw one of these in your media center you Plug in your ps3 and your Xbox and media PC and your okay Let's say you only have one console sorry sorry back up back up, okay, so you plug in your Xbox you plug in your media PC you plug in your TV to deliver firmware updates and whatnots or whatever else and then you got one more and you plug in Oh, I had another thing. I wanted to plug in but now I've forgotten Your network media player there there so you put all of these guys in here now They're all able to communicate via power line with your router And you don't have to have an actual switch plugged in behind your media center So it's just a cleaner way to set up the network in your household with power line Rather than breaking this out into a switch and then running everything all over the place.
