TRENDnet 16-Port Rack Mount USB KVM Switch, VGA and USB Connection, Supports USB and PS/2, Auto-Scan, Device Monitoring, Audible Feedback, Plug and Play, Hot Pluggable, Rack Mountable, Black, TK-1603R

Did some research for a KVM that supported both USB and PS/2. This one was right in my price range, and the option for payment plans was the icing on the cake! The only problem is that it doesn't include any of the cables to hook up to the devices that you want to use KVM with. No worries, Amazon sells those as well. Worked right out of the box, hooked it up to my Dell 17FP KMM, and bam. Had instant signal. Don't plan to use this too terribly often, as most of my equipment has remote access capability, but I wanted to be able to do KMM right in the enclosure. This is my first TRENDnet product, and am sufficiently pleased.

I am using this 8 port KVM to control two rackmount servers and two rackmounted Raspberry Pi 4 single board computers, with room to expand. It does not come with the cables to connect the KVM switch to your computers and requires proprietary cables that carry VGA and USB from the TRENDnet KVM switch to your computers. Any computers that don't have a VGA video output port ( such as the Raspberry Pi computers) will also require an appropriate adapter to convert the video output of the computer to a VGA output that will be able to connect to the TRENDnet KVM switch.One minor issue was with the hotkey documentation. The 8-port KVM switch is documented to be able to select an output by pressing Scroll Lock - Scroll Lock - <KVM port number> on your keyboard. So:Scroll Lock - Scroll Lock - 1should select KVM port #1. This was NOT the case. I had to make it a two digit number, adding a 0 in front of the KVM port number. So:Scroll Lock - Scroll Lock - 0 - 1is what I needed to select port #1.

This is the worst kvm I have ever bought, pc's configured with 1920x1080 resolution do not display, lower resolutions the screen kept flashing. Can't wait for replacement kvm from Amazon to show up. no, it is not a return or exchange for the same product, I bought another brand. I have other products from this company and they worked fine but this is by far worse than any other kvm I have ever bought

I rarely have time to review Amazon purchases. But I am absolutely stunned with the performance of this TRENDnet KVM switch. It took me less than 30 minutes to open up the shipping box, connect up five of my linux (Fedora 20) workstations (each with 64 cores!) and start testing all at a turtle's steady-and-slow pace.To switch the monitor between different workstations, I did the following:1) Hit the "Scroll Lock" twice on the keyboard (top right hand corner) => beeped (meaning enter the workstation numbers 1-8 to go to)2) Entered "4" on the numeric keypad (the numbered keys in rows/cols to the right of keyboard not on the typing pad) => beeped again (meaning the monitor has been switched to the desired workstation)3) Voila!Instead of "4" in Step 2) above, you could also hit the vertical up arrow on the numeric keypad and go to next available workstation. Do not do it unless you have all eight computers hooked up. Simply type the number of the computer that you wish to go to after hitting the "Scroll Lock" twice.Buy it! Think twice not! Do not forget to purchase KVM cables to hook it up. No cables are provided with this box. It is of course possible that it may not work for your set up but there is nothing universal in this world. The great thing about Amazon purchase is that you can return it with full refund should it not work for you. That is why we all love Amazon.This switch ranks among one of the top purchases I have ever made in my life. It is simply divine, particularly bearing in mind the price.Thank you Amazon for providing this great product.Thank you TRENDnet for inventing an awesome gadget. I am indeed following the trend. So should every other Amazon customer. Please follow the trend. Do not be left behind all alone.

This review is just an initial impression write up. I make NO CLAIM to durability or long term use. Mine arrived today. Having said that. I felt that this needed a write up.This is NOT the first KVM I have used. This replaces an about 10 year old Belkin Omniview E Series 4 port PS/2 KVM. I am a working IT professional that works in an environment that requires I keep up with software and technology trends for the data center, and provides diddly squat in training to keep up. So I have to do it on my own. So I built a home training network that simulates an enterprise network infrastructure on a small scale utilizing COTS hardware. Now I am not made of money, space, or power to setup and run this whole shebang. This is where the KVM comes in. My system density went beyond the 4 ports of the old Belkin, and even though the Belkin was working, sort of, with ps2 to usb adapters, the keyboard and mouse would frequently drop when switching between machines, and wouldn't come back without a reboot. (Thankfully rdp and ssh access is frequently still up!).This KVM came out of the box, looking every bit like a unit 4 times the price. The buttons are secure and solid, the LEDs are bright and clear. Yes it lacks an OSD, but in this application, if I can't keep what is attached where on the 8 ports I need to find a different career!I knew ahead of time this KVM would be picky about cables. Most KVMs are. Just order the cables that TrendNET recommends. Using the right cables for starters eliminates any excuses that their support people might drum up if you do have trouble. Likewise these cables are slim, and far less clunky to route than the old 1990s vintage cabling I was using with the Belkin.Likewise with the cables, KVM switches are known to be picky about keyboards and mice. I opted to use an older PS2 Microsoft Natural Elite keyboard, and a more recent HP optical mouse with scroll wheel that was in prior use with the Belkin. These are both fairly standard items without much chance for KVM incompatibilities.Once cabled up, and powered up, everything worked EXACTLY as expected. Scroll Lock - Scroll Lock - number of port to activate. Or push the button you need, and you are there, then move the mouse or hit the spacebar and you are good to go...So far, the only complaint I can come up with, and the reason I gave this 4 stars is this thing uses a wall wart type transformer instead of integrating the power supply into the casing. It's not like the casing doesn't have the room.On the plus side, this ships with rack mountable ears. Not that I have a switch rack (yet), but for those environments that DO have a need to rack it. The parts are there!Operating System compatibility isn't a problem. I presently have 6 systems hooked up to it, 3 Linux systems, a Windows XP box, a Windows 7 box, and a Mac. Keybinding for the Mac took some reading of the manual to get straight, but no big deal. None of the hosts dropped anything, keys, video, or mouse.Long story short, this is so far, a great KVM for a home office setup like mine, or even a staging / development type environment. However production server racks might want to opt for the OSD of the TK-804R instead. Then again, if your organization is good at keeping track of what machines are connected to what ports where, like mine is, then the OSD really isn't that big of a deal. Ease of installation so far has been a dream, as has compatibility with standard gear. I see some negative reviews here where folks are fussing about wireless or otherwise non standard / high latency keyboards and mice, and I have a hard time being sympathetic to them. KVMs are not intended to be used with high latency HID devices. Go old school and keep the cord and a basic board / mouse setup and you are far less likely to have trouble. Buy the correct cables with this KVM. Other KVMs come with cables already, but at a much higher cost, and with less flexibility on which cables you chose. I got a mix of 10 and 15 footers. At least I know my cables won't be too short!Lastly, this model has been out for a LONG time now, there was a Firmware update in July or so 2012. Check your mfg date, and if yours was built before say August 2012, (go to the MFG product page and click on Downloads, you will see it listed there) which fixes a lot of the issues folks may have with usb keyboards / mice.Oh and FYI, for TrendNET, if you'd like to update this model with an internal power supply (HUGE want that feature) and OSD (would be nice, but no big deal), keeping the same cables, I would be more than happy to beta test that thing for you!########## UPDATE 2/22/2013 ##########It's been over a month of fairly consistent, hard use, and this hasn't skipped a beat yet. I have also mulled over a lot of the reviews I have seen. One thing that concerns me about this KVM, which is the reported dying ports, I see a lot of reviews stating that 1 to 2 ports on these KVMs die off after say 3 months or so, with the longest term out was someone saying their ports died at about a year. While that hasn't happened to me (yet), I understand this is a problem. But TrendNET covers this product with a 2 year manufacturers warranty, and the reported customer service is excellent. I looked at competing products from iOgear, Linkskey, and others, I am confident this KVM not only does not suffer from unusually high failure rates, but from the reviews I am seeing here, and on various tech review sites, this KVM seems to be a bit more reliable than its competitors.My experience so far switching between hosts has been seamless. I have taken to using the keyboard shortcut because, well because it is fast and easy. Like I mentioned initially, I still don't like the wall wart transformer type power. I know it costs a little bit extra to build in the power supply, but I would be willing to shell out a few extra bucks for that. Simply put, the transformers are VERY inconvenient, and get in the way. Especially when trying to connect power up to an older UPS...########## UPDATE 7/5/2013 ##########So I guess it has been 7 months so far in use. I have been using it fairly frequently, not to the level we use our KVMs at work, but still fairly heavily used. Not a single drop yet. I presently have 5 servers, 4 cluster nodes, and 1 NAS filer head attached, as well as 2 workstations, a Windows XP, and a CentOS workstation. All is well so far. I do not see any reason for concern at of yet.
