 Welcome to an unboxing of a product that may not be glamorous, but is certainly useful. This is the Trendnet TK204 UK 2-port DVI USB KVM switch with audio kit. Slick bought one because he'd never heard of a KVM kit before. Slick's pretty technical, he'd heard of a KVM switch before. I see I called it a KVM kit, it's not even what it is. It's really late at night, guys. Here we are in the studio bringing you unboxings of KVMs. So Slick got this one because we have one for our Tech Tips setup, which has been working really well for us. We're not going to focus too much on this one, we'll focus on this one. But Slick, in his infinite wisdom, managed to find it useful in spite of the fact that he configured it wrong. See, what you're supposed to do is plug this... No, really, there's a reason that he didn't plug in the KVM's DVI cable and plug in a separate DVI cable. And I'll explain that as well. So let's actually get started with the unboxing. So you can get KVMs in a wide variety of different configurations, including ones that support two computers to be controlled with a single set of peripherals, ones that support four computers, even rackmount ones that support many computers operating off a single keyboard and mouse. And then you switch between them according to whichever one you want to control. You can get ones that use VGA and PS2. You can get ones that use DVI and USB. You can get ones that do support audio and ones that don't. For a consumer who happens to have a couple computers at their desk, whether you've got a PC and a Mac and you don't feel like dual booting and waiting for OS's to load in between, a lot of our graphic designers here at work do that. Or whether you have two desktop computers, one that is like a dedicated video rendering box and one that you use for gaming, for example, if you have them both at the same desk. This allows you to, with the touch of a button, switch between which one you want to control and hear at any given moment. So this guy includes everything you need. And this is the one that I consider to be most practical for probably 90% of consumers. So it comes with a wide variety of things here, including all of these packages that I have to open one by one in order to bring you this fantastic unboxing of a KVM. Alright, here we go. Ah, power. Okay, so the first thing, the things we don't need. Utility install user's guide. If you really need that, get it off the Trendnet website. Quick installation guide. Plug the things into the thing. It's that quick. Alright, here is the TK204U. So this is your console. This button you press to switch between computer one and computer two, there is a light that turns on to show you which computer you're operating at the current moment. Then you plug the keyboard and mouse that you want to use. In this case, we have some Microsoft thing and a Corsair mouse plugged into the USB cables at the front. Alright, speaking of people who don't know how KVMs work, I actually don't know what this one is for. Oh yeah, the main monitor. Well, then why isn't ours plugged in? Oh right, because he broke it. Okay, right. So moving on. So this is for the actual monitor that you're going to use for both computers. Then you've got your speakers as well as your microphone that you actually use and have sitting on your desk. On the back, you find two more sets of DVI. So these go out to the video cards of each of your computers and then you use... So here is the combo audio DVI cable. That looks just like that. So they've used a couple extra DVI pins here for audio. So you plug that in and you go like that. There you go. And then you use these USB cables to plug in to the USB port on the back of your computer. So by plugging these into your computers, you got your two computers, and then you've got all your peripherals and all of your speakers and microphone, as well as your monitor plugged in on this side, you can effectively control both computers with one set of peripherals. So here is the power for the KVM itself. It does need separate power. Not only can you switch between the computers here, but you can also set a hotkey on your keyboard to easily switch between the two computers. Now I'll explain why I kept sort of, you know, ragging on Slick here about his configuration. This is a DVI-I cable. Now there's a very good reason that this KVM has a DVI-I cable. That is because it is compatible not only with a digital signal, but also with an analog signal. The problem, though, is see those pins around that centerpiece? Okay, so we were testing a system that was using onboard video that has a DVI-D out. So that is a digital-only DVI connection. So what that meant was that when Slick had our monitor plugged into the KVM, and then he had this cable going out to here, he actually physically couldn't plug it in. And that is why it is Frankensteined right now and not hooked up correctly. So he does know what a KVM is. He does know how to hook up a KVM. I was just bugging him because I'm the one on camera and he's not allowed to say anything. So thank you for checking out my unboxing and first look, and extremely convoluted explanation of how KVMs work.
