Introduction

This IOGEAR DVI KVM Switch GCS1002 / GCS1004 allows users to access up to two
(GCS1002) or four (GCS1004) computers from a single USB keyboard, USB mouse, and
DVI monitor. It supports resolutions up to 1920x1200 @60Hz. With IOGEAR’s DynaSyncTM,
there is no more delay or change of video resolution when switching between, or booting the
computers. It also comes equipped with an audio line out and has power on detection – it will
automatically switch to the next powered-on computer when the other is turned off. It also
allows each computer to access any peripherals connected to the USB 2.0 port. And with its
audio enabled, users can listen to the audio output of each computer on one set of speakers.

The setup is quick and easy; users just need to plug the cables into their appropriate ports.

There is no software to congure. Since the GCS1002 / GCS1004 intercepts keyboard input

directly, it supports multiple computing platforms (PC x86 / x64, Macintosh PowerPC, and Sun
Microsystems Sparc).

There are three convenient methods users can use to access the computers: port selection
pushbuttons located on the unit’s front panel; hotkey combinations entered from the keyboard;
and mouse port-switching by simply double-clicking on the scroll wheel of a USB mouse to
change the ports.
