----------------- Introduction

Overview

The LevelOne Palm-Sized KVM, KVM-0205 and

KVM-0405 are computer switches that allows access to

two or four IBM compatible computers respectively from

one PS/2 keyboard, mouse and monitor. Switching

between computers is as easy as pressing the push

button or entering hot-key commands from your

keyboard. There is no interface card and software to

install and the LevelOne Palm-Sized KVM is independent

of the computer operating system.

Ready to run right out of the box, this Kit comes with

everything you need - a switch and complete cable sets,

just hook them up and go. By allowing one console to

manage all your computers, the LevelOne Palm-Sized

KVM eliminates the expense for extra consoles, the

spaces for extra peripherals and the time hopping around

for accessing different computers.

power and is designed to run reliably without an external

power adapter.
