THE ACS335A KVM-EXTENDER FAMILY

Welcome to the ACS335A KVM-Extender

Family!

Thank you for purchasing a ACS335A KVM-Extender model. We appreciate your business,

and we think you’ll appreciate the many ways that your enhanced keyboard/video/ mouse

system will save you money, time, and effort.

That’s because our ACS335A KVM-Extender not only allows you to remotely locate a

console (Monitor, Keyboard, Mouse + optional serial/audio devices) over great distances

without any loss in signal quality (up to 1000m/3250ft) but also to do this in an EMI

hazardous environment.

Wherever you have great distances: airports, roller plants, distributed data centres; or in a

range of applications where you have large electromagnetic generators or loads, magnetic

resonance tomographs, induction furnaces, current generators; the ACS335A KVM-Extender

is a solution for remotely locating your console. Two different models cover a range of

applications: a KVM extender for a standard remote console – Monitor, Keyboard and

Mouse; and a second unit with KVM extension and additional serial and bi-directional audio

support. This device is also suitable for computers equipped with a serial mouse or touch

screen.

This manual will tell you all about your new ACS335A KVM-Extender, including how to

install, operate, and troubleshoot it. For an introduction to the Extender,

see Chapter 2. The Extender product codes covered in this manual are:

ACS335A: KVM-Extender for VGA, PS2-Keyboard/Mouse

ACS335A-AS: KVM-Extender for VGA, PS2-Keyboard/Mouse + Serial/Audio

FCC/CDC STATEMENTS

FEDERAL COMMUNICATIONS COMMISSION

AND CANADIAN DEPARTMENT OF COMMUNICATIONS

RADIO-FREQUENCY INTERFERENCE STATEMENTS

This equipment generates, uses, and can radiate radio-frequency energy, and if not installed

and used properly, that is, in strict accordance with the manufacturer’s instructions, may

cause interference to radio communication. It has been tested and found to comply with the

limits for a Class A computing device in accordance with the specifications in Subpart B of

Part 15 of FCC rules, which are designed to provide reasonable protection against such

interference when the equipment is operated in a commercial environment. Operation of this

equipment in a residential area is likely to cause interference, in which case the user at his

own expense will be required to take whatever measures may be necessary to correct the

interference.

Changes or modifications not expressly approved by the party responsible for compliance

could void the user’s authority to operate the equipment.

Shielded PC-equipment cables must be used with this equipment to maintain compliance with

radio frequency energy emission regulations and ensure a suitably high level of immunity to

electromagnetic disturbances.

This digital apparatus does not exceed the Class A limits for radio noise emission from digital

apparatus set out in the Radio Interference Regulation of the Canadian Department of

Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites

applicables aux appareils numériques de la classe A prescrites dans le Règlement sur le

brouillage radioélectrique publié par le Ministerié des Communications du Canada.

SAFETY PRECAUTIONS AND INSTALLATION GUIDELINES

Safety Precautions and Installation Guidelines

To ensure reliable and safe long-term operation, please note the following installation

guidelines:

•Only use in dry, indoor environments.

•The Remote unit, Local unit and any power supplies can get warm. Do not locate them

in an enclosed space without any airflow.

•Do not place a power supply directly on top of a unit.

•Do not obstruct a unit’s ventilation holes.

To safeguard against personal in ury and avoid possible

damage to equipment or property, please observe the

following:

•Only use power supplies originally supplied with the

product or manufacturer-approved replacements. Do not

attempt to dismantle or repair any power supply. Do not

use a power supply if it appears to be defective or has a

damaged case.

•Connect all power supplies to grounded outlets. In each

case, ensure that the ground connection is maintained

from the outlet socket through to the power supply’s AC

power input.

•Do not attempt to modify or repair this product

OVERVIEW

2. Overview

2.1 Introduction

With a fibre KVM Extender you can dramatically increase the maximum distance between a

CPU and its Console – the keyboard/mouse and monitor (+ serial/audio devices). In addition,

they are essential for installations in hazardous EMI environments. Normal

keyboard/mouse/monitor extender cables (and Extenders using regular cables) have lower

extension capabilities and EMI interference may further reduce the maximum distance and

reliability. The ACS335A fibre optical KVM Extender System has none of these limitations.

Locate your CPU in a secure cabinet or data centre and access it remotely from a distance of

up to 1000m.

A basic KVM extension system comprises a Local unit (transmitter) and a Remote unit

(receiver). The Local unit connects directly to the computer (or a KVM switch system) using

the supplied cable(s). The user console (keyboard, mouse and monitor) attaches to the

Remote unit. The Remote and Local units communicate video and data information along the

interconnecting cable. Local units offer dual access, allowing the connection of a second user

console close to the computer. With the optional upgrade kit, you can also use the units to

communicate stereo audio and serial port signals.
