Introduction

Overview

The CS1768 8-port USB DVI KVM Switch is a control unit that allow access and control of up to 8 computers from a single USB keyboard, USB mouse, and monitor (DVI or VGA) console. It can be cascaded to three levels – allowing up to 73 CS1768s to control up to 512 computers – all from the original single console. In addition, the CS1768 comes with ATEN’s new Video DynaSync technology, which optimizes display resolution.

There are three convenient methods to access any computer connected to the installation: (1) using the pushbutton port selection switches located on each unit's front panel; (2) entering Hotkey combinations from the keyboard; and (3) selecting from menus provided by the on-screen display (OSD). An Auto Scan feature also permits automatic scanning and monitoring of the activities of all computers running on the installation one by one.

The CS1768 provides multimedia keyboard support and is audio enabled. Two microphones can provide audio input to each of the computers, and you can listen to the audio output of each computer on two sets of speakers (on a oneat-a-time basis).

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 CS1768 intercepts keyboard input directly, it works on multiple operating platforms (PC compatible, Mac*, Sun*, etc.).

Since a single console manages all of the computers on your installation, a CS1768 KVM switch setup: (1) eliminates the expense of having to purchase a separate keyboard, monitor, and mouse for each computer; (2) saves all the space those extra components would take up; (3) saves on energy costs; and (4) eliminates the inconvenience and wasted effort involved in constantly moving from one computer to another.

Note: For PC compatible computers. Mac and Sun computers must use the

USB cable connections (see Cables, page 5).

Hardware Setup

Overview

For convenience and flexibility that allows mixing multiple plat forms, the CS1768 design utilizes custom USB DVI KVM cables that serve as intermediaries between the switch and the connected computers (refer to the installation diagram on page 17).

A separate custom USB DVI KVM cable is required for each computer connection. The custom KVM cables are listed under Cables, on page 5. Consult your dealer to find out which custom KVM cables best fit your needs.

Stacking and Rack Mounting

The CS1768 can be stacked on the desktop or rack mounted at the front or rear of the rack. The following sections take you through the procedures for each method.

Note: 1. Allow at least 5.1 cm on each side for adequate ventilation and

12.7 cm at the rear for power cord and cable clearance.

2. The standard rack mounting kit does not include screws or cage nuts. If you need additional screws or cage nuts, contact your rack dealer.

Stacking

The CS1768 can be placed on any level surface that can safely support its weight and the weight of the attached cables. Make sure that the surface is clean and free of any materials that can block the exhaust vents or otherwise interfere with normal operation of the switch.

To place the CS1768, or to stack units if you are cascading them, remove the backing material from the bottom of the rubber feet that came with this package, and stick them onto the bottom panel at the corners, as shown in the diagram, below:
