Keyboard Video Mouse (KVM) Switch Boxes

Computer switch boxes are the perfect fit for tight situations
By Michael Berman A keyboard, video, mouse switch box, better known as a KVM switch box lets you use one keyboard, monitor and mouse with several computers, which can be the ideal solution for offices that are tight on space.

KVM switch boxes have come a long way since their inception, offering tons of new features making it easy for so-called "power users" to adapt them to their needs. A few of the key features available on today's breed of computer switch boxes are:

1. You can choose between DVI and VGA video.

2. Many of the newer KVM switches allow you to interface with USB ports for keyboards and mice.

3. You can get a simple keyboard, video, mouse switch box for two computers or expand to a whole office full of machines.

4. Most KVM switch boxes have a very small footprint, so they take up very little space on your desk.

Develop a game plan for keyboard, video, mouse switch boxes

Since keyboard, video, mouse switch boxes come in so many variations, it's a good idea to plan out where you want to set them up, what they'll be used for and how many computers they'll be connected to.
Try:  Companies such as Tron and Lindy can guide you as to what type of KVM switch to purchase, whether it's to accommodate a roomful of servers or just a couple of desktop computers.

Get the right port-KVM switch match

All of the options, from USB and firewire to standard mouse and keyboard ports can be confusing. Knowing the configuration you need for keyboard switchers, and mice and video connections can save a lot of headaches when setting up your KVM boxes.
Try:  To get an idea of what configurations are available for keyboard switchers and other devices, check out Avocent and Rose Electronics.

Know what cables you need for computer switch boxes

Whether it be CAT-5 cables for a sophisticated network or simple DVI, VGA, USB or other video mouse and keyboard cables, make sure the KVM boxes you buy have the correct ports to work with your system.
Try:  Make sure you have plenty of extra cables of various lengths to hook up your computer systems to the KVM boxes. A few good sources for all types of CAT, video and other cables include Rose Electronics, TigerDirect and Cables to Go, which custom-builds cables.

• Choose electronic switching over manual switches. Although most of the newer keyboard switcher models use electronic switching, there are still a few bargain boxes out there that use manual A-B switches.
• Have the right configuration of cables and boxes. There's nothing worse than discovering after you've purchased boxes set up with VGA video and standard keyboard and mouse ports that your monitors and PCs are set up for DVI (high resolution) video and your mouse and keyboard are USB.
• Test the keyboard switcher before you buy. Since these are electronic devices, the chances of them not working without a hitch are slim to none. Work with a consultant that lets you hook them up and test them before you buy or a retailer with a decent return policy.
