Introduction

Overview

The CS1798 / CS17916 8/16-port USB HDMI KVM Switch is a multi-purpose
appliance that consolidates access and control of up to 8/16 HDMI computers
from a single USB keyboard, USB mouse, and monitor console. The CS1798
/ CS17916 can be cascaded up to three levels – to control up to 512 computers
(CS1798); or two levels – up to 256 computers (CS17916) – all from a single
console.

In addition the CS1798 / CS17916 features multi-display functionality, which
enables the use of standard USB cables to stack up to eight switches in a multi­display installation where each computer is fitted with multiple video cards.
Furthermore, the CS1798 / CS17916 comes with ATEN’s Video DynaSync

TM

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 all computers on the
installation, one by one.

The CS1798 / CS17916 provides multimedia keyboard support and is audio
enabled. You can listen to the audio output of each computer on two sets of
speakers (on a one at- 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 CS1798 / CS17916 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
CS1798 / CS17916 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 extra components 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: 1. The CS1798 / CS17916 offers two types of installation – 1)

standalone/cascade; and 2) multi-display – that require different

CS1798 / CS17916 User Manual

2

cabling setups. Therefore, the functions of both types are not
available in one installation.

2. For PC compatible computers. Mac and Sun computers must use the
USB cable connections (see Cables, page 6).

Hardware Setup

Overview

For convenience and flexibility that allows mixing multiple platforms, the
CS1798 / CS17916 design utilizes custom USB HDMI KVM cables that serve
as intermediaries between the switch and the connected computers (refer to the
installation diagram on page 20).

A separate custom USB HDMI KVM cable is required for each computer
connection. The custom KVM cables are listed under Cables, on page 6.
Consult your dealer to find out which custom KVM cables best fit your needs.

Installation Types

The CS1798 / CS17916 offers two types of installation – 1) standalone/
cascade; and 2) multi-display – that require different cabling setups. Therefore,
the functions of both types are not available in one installation. See the
following sections in this chapter for details about the different cabling
requirements.

Before You Begin

1. Important safety information regarding the placement of this
device is provided on page 67. Please review it before
proceeding.

2. Make sure that power to all devices that you will be installing
has been turned off. You must unplug the power cords of any
computers that have the Keyboard Power On function.

Stacking and Rack Mounting

The CS1798 / CS17916 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 CS1798 / CS17916 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 CS1798 / CS17916, 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:

Rack Mounting – Front

1. Remove the screws, one each from the left and right sides of the switch
near the front of the switch.

2. Use the M3 x 8 Phillips hex head screws supplied with the rack mounting kit
to screw the rack mounting brackets into the sides near the front of the unit.

3. Place the KVM switch in the rack. Position it so that the holes in the
mounting brackets line up with the holes in the rack. Secure the mounting
brackets to the front of the rack.
