5.0 out of 5 stars Great KVM with USB DDM, July 19, 2013 by RushiMP

This review is from: ConnectPRO 2-port DVI USB KVM Switch w/DDM UD-12+KIT1F (Personal Computers)

The ConnectPRO is a solid KVM device.

Most KVMs emulate generic keyboards and mice, not ConnectPRO. My fancy keyboard, gaming mouse, USB thumbdrive, Joystick, Driving Wheel, etc all can find a happy place to exist on this KVM.

The device uses Dynamic Device Mapping technology to ensure a solid stable connection without emulation. The device passes real device information between the KVM and the connected computers. This makes generic device emulation unnecessary as the DDM allows each connected computer system to believe all connected I/O devices are remaining connected even as the KVM switch might move to another port.

I enjoy to play games on a high end SLI gaming rig, but I also have a dedicated multiprocessor workstation. I am also pleased to report that unlike some other devices there is no significant input lag in gaming, and there is a very stable connection for work.

Overall, this is the best KVM I have ever used, and I am very impressed with the ConnectPRO device and included cables. Do not make the mistake I did and get a lesser solution only to find out it does not like your modern peripherals or can't be used with a thumbdrive.


5.0 out of 5 stars A great accessory I didn't know I needed, March 8, 2013 by J. Summers "Baseball Epistemologist" (Chandler, AZ United States)

This review is from: ConnectPRO 2-port DVI USB KVM Switch w/DDM UD-12+KIT1F (Personal Computers)
I've always looked at a KVM switch as an unnecessary luxury. In typical guy fashion I was perfectly content with having keyboards and mice strung everywhere similar to the table full of remote controls for the various electronics connected to my television. My realization of the need for a KVM occurred after spending 20 minutes searching the stack of wireless keyboards to find the one connected to the server I was working on. In that moment of frustration I decided it was the perfect time to buy new toys and a KVM switch was something I could not live without. After doing research on what was important in a switch I concluded the ConnectPRO DVI switch was the way to go. At first I was focused strictly on the types of video connections thinking all switches were the same. That is definitely not the case. Having a keyboard switch with Dynamic Device Mappng (DDM) was extremely important. DDM allows for better emulation of USB devices especially keyboards which have a tendency to be somewhat temperamental when shared.
The ConnectPRO arrived quickly and was well packaged with great instructions. In a deviation that put my man-card into jeopardy I actually read the instructions. They were clear and concise. In hindsight I am not exactly sure why I felt it necessary to read the instructions on a 2-port KVM switch. I mean I had a 50/50 chance of plugging things in correctly. But it was still a red-letter day for the male species that I actually found the instructions and did not discard them as part of the packaging.
The switch itself has worked well with the exception of the Microsoft Entertainment 7000 Wireless Mouse and Keyboard. This device caused nothing but grief with the KVM and after a quick check with ConnectPRO they confirmed that keyboard/mouse combination was troublesome for their switches (and pretty much every switch on the market which leads me to believe it is more a Microsoft problem than a KVM manufacturer problem). After replacing the keyboard and mouse with a more standards based interface my problems went away. Switching between the two computers are simple and easy with the pre-lit buttons. A nice touch is the multi-colored lights that let you know if things are connected correctly. If a computer does not have power or is not connected via the DVI connector the light will show as red so you are not left wondering whether it is a cable problem or a switch problem. A green button shows the switch thinks everything is connected appropriately. There are two colors of green to differentiate between the active port and the other so you aren't left guessing which one is currently selected.
Overall the ConnectPro has worked flawlessly. My only regret is that I didn't get one of these sooner. The pile of keyboards and mice is slowly dwindling being replaced by a handful of ConnectPro switches thereby eliminating the possibility that my wife will nominate me to be featured on a new reality show for keyboard/mouse hoarders.

5.0 out of 5 stars Very nice unit, January 30, 2013 by James Dulgerian

This review is from: ConnectPRO 2-port DVI USB KVM Switch w/DDM UD-12+KIT1F (Personal Computers)
Very well constructed, works without AC adapter. For some reason will not send keystrokes after PC reboot to enter BIOS or boot options. Tried with AC adapter plugged in but still didn't work. Also will not resync if you switch away from and back to a site streaming audio and/or video. Resetting doesn't resolve. Otherwise very satisfied.

5.0 out of 5 stars Just plain works, September 15, 2012 by wz25

This review is from: ConnectPRO 2-port DVI USB KVM Switch w/DDM UD-12+KIT1F (Personal Computers)
Didn't purchase this from Amazon, but since I used the site to read up on the device, I thought I'd contribute.

This currently switches between two docked notebooks, one running W7, and the other XP. Both PCs share a mechanical KB, high-DPI mouse, and a Dell 2007DP monitor. Switch speed is nearly instantaneous for the monitor, and even faster for the KB/mouse. No issues whatsoever with device detection, nor resolution maintenance.

The UD-12+KIT1F comes with a nice set of cables (edit: two DVI-I/USB cables for peripheral hookup and an RJ45 --> serial cable for FW upgrades), a single DVI-I to DVI-D adapter, and a 5V PSU; the PSU was not required in my case, but a nice touch nonetheless. I have to use DVI-I --> DVI-D adapters for both docks, and have no issues whatsoever.

I've also used this just to switch KB/mouse in conjunction with a separate DVI switch while waiting for my second DVI-I --> DVI-D adapter to arrive. Again, no issues.

This isn't the cheapest option by far, but worth the cost simply for the time/frustration saved. Make sure that you have a second DVI-D (24+1 Male) to DVI-I (24+5 Pin Female) adapter/converter if your setup requires it.

Update: Tested with wireless Logitech VX mouse-- works perfectly. Also tested flash drive switching using the front ports, and again, flawless switching.

Thanks for a great product.  I have been searching for a reliable solution for Mac/Win keyboard switching.  After years of frustrating near misses (especially software solutions), yours is the only stable solution.

Greg "PTON tiger", 5 Stars - "Works perfectly on DVI and all new Wireless USB devices! A++"

I have been searching for a KVM to allow sharing of my monitor, logitech wireless mouse, wireless keyboard and other USB devices. This thing is sweet! It works like a charm and switches flawlessly between systems. It takes 2 seconds to switch and everything works like a charm.

I have Logitech Dinovo Wireless Keyboard and Logitech Wireless MX Laser Mouse and they worked out of the box between my two computers. No need to worry about switches, lags, can push the 1/2 button to switch or use hotkeys on your keyboard. Their techsupport is great, had to call with a question and a guy picked up the phone right away - they can make custom firmware if your device does not work. Its a small company (like 25 employees) that is all about their niche and their customers. Their DDM and special active switching tech is not found in the cheaper competing models and the tech allows split second switching and response time - no mouse, keyboard lag and instant resolution correction. It remember the settings, saves to box so its a quick switch.

Although its expensive, this thing works and works really well. Supports my 1080P monitor between my Window 7 x64 desktop and my thinkpad, windows XP docking station. It just works, no headaches, firmware, or other installs needed. Works great for a home office where you bring home your work laptop and want to use your existing monitor, mouse, keyboard withouth have to always plug-in/out cables.

Kit comes with small switching box, power cord, 2 sets of combo DVI/USB (big square to rectangle for computer) cables to connect to your devices. I had tried IOgear, Belkin, etc...and none of them worked with these newer wireless USB devices until ConnectPro. Furthermore, this has 2 USB ports in the front to share USB devices between computers; the mouse and keyboard have specific back USB slots.

One thing to note, you may have to uninstall logitech setpoint for this to work 100% and if your DVI plug doesnt have the 4 pin setup around the long flat metal pin, you will need a convertor (like 3$ on amazon). Plus it doesnt KVM sound, but who cares!

Buy this and you won't be dissapointed.

I followed the simple instruction sheet, so there were no issues. My Microsoft wireless desktop dongle worked, in the keyboard USB port, with no loss of functionality in the mouse or the keyboard. The hotkeys work without issue on the box and keyboard. I am running my monitor's USB hub through one of the devices front USB ports, with a Logitech web cam serialized onto the monitor hub. No problems seeing all of this connectivity instantly on both Ubuntu Linux 10.04 Lucid and Microsoft Windows 7. So far so good. The pictures don't do the unit justice. Switching between systems is smooth as silk, with no delays, thanks to the DDM and DDC. BTW, the supplied cables are DVI-I single link with pins for analog support. If you need DVI-D, get some adapters or other cables to connect your video. I happened to have DVI-D on both computers, and HDMI on the monitor and the necessary cables.
