----------------- 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.
