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.

I recommend: 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.

I recommend: 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.

I recommend: 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.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  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.

A KVM (or Keyboard, Video, Mouse) switch box allows users to set up and handle multiple computers or servers using one of each of these control elements. KVM can make a business a lot more efficient as "rack-stored" servers or other hardware can have a "central command workstation." Businesses that want to profit from the efficient control that KVM provides can learn a lot about the most common terms and technology for KVM switch boxes and discover how to implement this kind of technology.

USB or Universal Serial Bus

USB is a new kind of universal connection for peripherals. Almost all new computers have these small, rectangular ports for attaching all kinds of printers, scanners, mice, keyboards, cameras and more. Lots of KVM switch boxes have USB included to make connectivity easier.

I recommend: Find out more about USB connectivity at the product advocacy site at USB.org.

DVI or Digital Visual Interface

DVI is also sometimes called a 'digital video interface'-this kind of graphical setup is used to optimize the visual quality of flat screens. The new DVI technology is one option for using KVM switch boxes.

I recommend: Learn about DVI systems, cabling and more at WiseGeek.

VGA or Video Graphics Array

VGA is another visual option for using KVM switches to work monitors: VGA was originally made for use with traditional tube monitors.

I recommend: Find definitions and links to more on VGA at Mimi.hu.

Firewire

Another kind of connectivity KVM switch boxes use is called firewire. This high-speed, serial bus design leads to faster connectivity for multiple peripherals. Some see firewire as a 'bulked-up' USB design.

I recommend: Check out more on firewire connectivity at this Tech FAQ.

CAT 5

The cable type called Category 5 is a leaner, more versatile component that has replaced bulkier cabling for most KVM switch boxes and other hardware. CAT 5 is now an ethernet standard, and is often used with KVM boxes.

I recommend: Find a definition of CAT 5 KVM as well as links to detailed product specs at 42U.

On screen display

This feature allows the KVM switch box to be handled with a screen display control.
