THE VTO2/VRO2 V6.00 KVM-EXTENDER FAMILY

Welcome to the VTO2/VRO2 V6.00 KVM-

Extender Family!

Thank you for purchasing a VTO2/VRO2 V6.00 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 VTO2/VRO2 V6.00 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 VTO2/VRO2 V6.00
KVM-Extender is a solution for remotely locating your console. Three different models cover
a range of applications: a VGA-only extender – for when you just need a remote display
screen; a KVM extender for a standard remote console – Monitor, Keyboard and Mouse; and
a third 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 VTO2/VRO2 V6.00 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:

K234-9W: KVM-Extender for VGA, PS2-Keyboard/Mouse + Serial/Audio

K235-9W: KVM-Extender for VGA, PS2-Keyboard/Mouse

K236-9W: Extender for VGA only

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 VTO2/VRO2 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.

2.6 How to Use This Guide

This guide describes the installation and configuration of the VTO2/VRO2 V6.00 KVM­Extender Series. Although the connection and operation of the system is relatively
straightforward, you should consider the following before getting started:

Connection & Compatibility

If you have purchased a VTO2/VRO2 V6.00 KVM-Extender Kit, this will contain all the
cables required to connect the Local unit to your PC or KVM switch. The Remote console
(keyboard, monitor and mouse) and any audio and serial equipment connect directly to the
Remote unit.

For information about connection and installation, see Installation, page 13.

Graphic Source (RGB or VGA)

The device can transmit RGB signals as well as VGA. In addition, it is able to convert from
VGA to RGB as well as from RGB to VGA.
Factory setting: VGA (see page 27).

Fibre Cable (50µ or 62,5µ)

The VTO2/VRO2 V6.00 KVM-Extender can be used with 50µ or 62,5µ fibre cable. The
transmission power must be adjusted to the type of cable. You need not to modify the setting,
if at least one of the following two circumstances become true: 1st the cable type is 50µ, 2nd
the cable length exceeds 100m. (see also page 27)

Automatic Gain Control (AGC)

In some applications (e.g. RGB Signals) it may be necessary to switch off the Automatic Gain
Control.
Factory setting: Automatic Gain Control ON (see page 27)

Compatibility

The devices in version 6.00 are NOT compatible with previous versions.

INSTALLATION

3. Installation

For first-time users, we recommend that you carry out a test placement, confined to a single
room, before commencing full installation. This will allow you to identify and solve any
cabling problems, and experiment with the KVM extender system more conveniently.

VTO2/VRO2 V.6.00 –5 STRAND KVM-EXTENDER

3.2 Interconnection Cable Requirements

CPU/Local Unit Connections

To connect the Local unit to your graphic source you will need:

• VGA (K236-9W): Connect the supplied VGA CPU-cable 1,8m (HD15 male / HD15

female) to the CPU (KVM - Switch, etc.). Please ensure that the connection is tension­free.

• VGA, Keyboard, Mouse (K234-9W + K235-9W): Connect the supplied VGA CPU

cable, ZIP type 1,8m (HD15 male / HD15 female, 2x PS2 male / PS2 male) to the CPU
(or KVM Switch). Please ensure that the connection is tension-free.

Power Supplies

Connect the supplied 6V/DC power supplies to the Plug terminals on the rear of both the
Local and Remote units.

Local Unit/Remote Unit Connection

To connect the Local and Remote units you will need:

• Multimode Fibre Cable: 3 Fibres 50µm or 62.5µm – ST-plugs. (K236-9W)

Multimode Fibre Cable: 5 Fibres 50µm or 62.5µm – ST-plugs. (K234-9W+K235-9W)

If you want to use the devices with fibres 62,5µ AND the

cable length falls short of 100m, it might be necessary,
to reduce the optical budget. For this purpose, optical fibre
pigtails are available. (see also page 10).

INSTALLATION

3.3 System Setup

To install your VTO2/VRO2 V6.00 KVM-Extender system:

1. Switch off all devices.

2. Connect your keyboard, monitor, mouse, audio device and serial device to the Remote

unit (depending on type of device). Ensure that you attach the keyboard and mouse
connectors to the correct ports. The keyboard connector is purple; the mouse connector
is green.

3. Connect the CPU to the Local Unit, using the supplied CPU cable. Ensure that you

attach the keyboard and mouse connectors to the correct ports. The keyboard connector
is purple; the mouse connector is green.

4. Connect the 6V power supplies to the Local and Remote units.

Only use the power supply originally supplied with this

equipment or a manufacturer-approved replacement.

5. For a dual access system, connect the keyboard, mouse and monitor for the Local

console to the appropriate ports on the Local unit. The ports may also be used to feed
into a KVM switch.

6. Connect the Interconnection cable (Multimode Fibre Cable) from the Remote unit to the

Local unit. Ensure that you attach the fibre connectors to the correct ports. R goes to R,
G to G, B to B, 1 to 1 and 2 to 2.

7. Power up the system.
