Introduction

Overview

The CS72D / CS74D 2/4-Port USB DVI KVM Switch allows you to control two or four computers using one USB mouse, USB keyboard and Digital Visual Interface (DVI) monitor console. It supports digital video devices, such as flat panel displays, data projectors, plasma displays and digital TVs.

The CS72D / CS74D comes with ATEN’s Video DynaSync which eliminates boot-up display problems and optimizes resolution; as well as Power On Detection, which means if one computer is powered off, the CS72D / CS74D automatically switches to the next powered-on computer.

The CS72D / CS74D is audio enabled. You can listen to the audio output of each computer on a single set of speakers on a one-computer-at-a-time basis. It also permits each computer to access any peripherals connected to the USB ports.

Setup is fast and easy; simply plug cables into their appropriate ports. There is no software to configure, no installation routines, and no incompatibility problems. Since the CS72D / CS74D intercepts keyboard input directly, it works on multiple computing platforms (PC x86 / x64, Macintosh PowerPC, and Sun Microsystems Sparc).

technology,

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

There is no better way to save time and money than with a CS72D / CS74D installation. Since a single console manages all of the computers, the CS72D / CS74D setup: eliminates the expense of having to purchase separate console components for each computer; saves all the space those extra components would take up; saves on energy costs; and eliminates the inconvenience and wasted effort involved in constantly moving from one computer to another.
