Introduction

Overview

The Master View CL-1758 KVM Switch is a control unit that allows access to

multiple computers from a single keyboard, monitor, and mouse (KVM)

console. Before the development of the Master View, the only way to control

multiple computer configurations from a single console was through a complex

and costly network system. Now, with the Master View CL-1758, you can

easily access multiple computers in a cost effective manner.

A single Master View CL-1758 can control up to 8 computers. Since the

CL-1758 supports cascading to three levels, in a complete three stage

installation, up to 72 Master View CS-1758 models can be cascaded from the

CL-1758 to control up to 512 computers - all from the original single console.

The Master View CL-1758 offers a space-saving, streamlined approach to

KVM switch technology by integrating a keyboard, LCD monitor, and

touchpad in a Slideaway™ housing. The LCD display is built into the cover;

the keyboard and touchpad are built into the base. Slide the KVM module

section out; flip the cover up; and you are ready to go to work. When finished,

flip the cover down and slide the KVM module away.

For further convenience and flexibility, the switch also supports an external

keyboard, monitor, and mouse console. Although external consoles often use a

PS/2 keyboard and mouse, the CL-1758 supports both PS/2 and USB

computers. Depending on the cable you use to link the switch to the computer,

you can attach to a computer with PS/2 connectors or USB connectors.

(See Cables, page 4, for more details.)

The Slideaway™ housing is 1U high for easy rack mounting, and because of

its modular design, the KVM section can be detached from the switch section.

The CL-1758 also features high density 15 pin KVM connectors instead of the

usual 25 pin kind. This space-saving innovation provides more reliable and

efficient transmission of KVM data, at the same time that it reduces cable

clutter.

Your CL-1758 investment is protected by an included Firmware Upgrade

Utility. You can stay current with the latest functionality improvements by

downloading firmware update files from our website as they become available,

and using the utility to quickly and conveniently perform the upgrade.

CL-1758 User Manual

Access to any computer connected to the installation is easily accomplished

either through a powerful, mouse driven, OSD (On Screen Display) menu

system, or by entering Hotkey combinations from the keyboard. A convenient

Auto Scan feature also permits automatic scanning and monitoring of the

activities of all computers running on the installation one by one.

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 CL-1758 intercepts keyboard input directly, it works on

multiple operating platforms (PC compatible, Mac*, Sun*, etc.).

There is no better way to save time and money than with a CL-1758

installation. Since a single console manages all of the computers, the CL-1758

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.

* Mac and Sun computers must use the USB cable connection (see p. 4).

Hardware Requirements

Computers

The following equipment must be installed on each computer:

 A VGA, SVGA or Multisync card.

Note: The integrated LCD monitor's maximum resolution is 1024 x 768 @

75Hz (15") or 1280 x1024 @ 75Hz (17"). Make sure that the

computer resolution settings do not exceed the LCD monitor's

maximum resolution.

 Either a Type A USB port, or PS/2 keyboard and mouse ports (see the

Cables discussion in the next section).

Cables

Only the following ATEN Custom KVM cable sets may be used with these

switches.

Depending on the KVM cable type, the switches can link to computers that use

PS/2 connectors to transfer keyboard and mouse data as well as computers that

use USB connectors (see the installation diagram on p. 12).

To purchase ATEN Custom KVM cable sets, contact your dealer.

Note: 1. Two cables are provided with this package.

2. For PS/2 port computers, we strongly recommend using 2L-5702P

cables. While the other cables work, the keyboard and/or mouse will

not work if all their connectors (keyboard, video, and mouse), aren't

plugged into their ports on the computer before starting the computer

up. The 2L-5702P cables do not have this limitation.
