REPEATER/CROSS- REPEATER

Welcome to the Repeater/Cross- Repeater Family!

Thank you for purchasing a Repeater/Cross- Repeater! We appreciate your business, and we
think you’ll appreciate the many ways that your Repeater/Cross- Repeater system will save
you money, time, and effort.

That’s because our Repeater/Cross- Repeater allows, to double the total allowed distance of a
DVXi KVM Extender system for remotely locating a console (DVI-monitor, keyboard and
mouse).

Wherever long distances are usual, e.g. airports, industrial plants, call- centres or in
distributed computer centres, the Repeater/Cross- Repeater is the best way, to solve all
problems in remotely locating your console. 6 different types are available: There are three
types for repeating the signals and doubling the distance and three types to extend the
distance and simultaneously convert from one medium to another (e.g. CATx to Multimode).

This manual will tell you all about your new Repeater/Cross- Repeater, including how to
install, operate, and troubleshoot it. For an introduction to the Repeater/Cross- Repeater, see

Chapter 2. The Repeater/Cross- Repeater product codes covered in this manual are:

SAFETY PRECAUTIONS AND INSTALLATION GUIDELINES

Safety Precautions and Installation Guidelines

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

• Do not use CATx-devices to link between buildings – please use fibre devices.

• Only use in dry, indoor environments.

• If the building has 3-phase AC power, try to ensure that equipment connected to the

Local and Remote units is on the same phase.

• Try not to route a CATx link cable alongside power cables.

• The Repeater/Cross- Repeater and any power supplies can get warm. Do not locate them

in an enclosed space without any airflow.

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

• Do not obstruct a unit’s ventilation existing holes.

To safeguard against personal injury 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, or make

a connection from the interconnection link interface to
any other products, especially telecommunications or
network equipment.

REPEATER/CROSS- REPEATER

2. Overview

2.1 Introduction

A KVM Extender is used, to extend the distance between a CPU and its Keyboard / Monitor /
Mouse considerably. The allowed distance is limited by the physics and the make of the
cables.

If the total distance expires the allowed distance, Repeater may double the total allowed
distance.

In some environments, the signal path may be inhomogeneous. This means, a part might be
based on CATx, another part in Multimode. The Cross- Repeater hereby allow to convert
from one medium to another, without laborious regaining the original signals and resending
them.

The Repeater/Cross- Repeater described in this manual are especially designed for the DVXi
KVM Extender Family. Operation with other products is not possible.

REPEATER/CROSS- REPEATER

2.4 Features

The Repeater/Cross- Repeater offer the following features:

• Support for DVXi KVM- and Media- Extender (all devices)

• Support for Draco™ KVM- and Media- Extender (all devices)

• When installing the Repeater device in the middle of a link, it will allow to double the

total distance. (e.g. CATx up to 2x140m = 280m). Under all other circumstances, the
cable on each side of the Repeater/Cross- Repeater may have the usual maximum
distance (e.g. CATx up to 140m, Multimode 50µ up to 400m, ...).

• When installing a Cross- Repeater device, the cable on each side of the Repeater/Cross-

Repeater may have the usual maximum distance (e.g. CATx up to 140m, Multimode 50µ
up to 400m, ...).

Attention!
actually DVXi CATx and Fiber devices must not be used assorted. This
means, it’s not allowed, to connect a DVXi CATx Local Unit with a DVXi

Fiber Remote Unit. So actually Cross- Repeater can be used only in pairs.

For Dual- Head devices you need two pieces Repeater (one for each of the
two interconnection cables). A Dual Cross- Repeater CATx to Fiber
(Multimode or Singlemode) is available.

• The maximum screen resolution as well as the support of other interfaces like USB-HID,

serial, audio, ... only depends on the type of used Extender.

• Status indicator LEDs on each device.

• Small footprint chassis.

• Rack mount options available.

• Universal switch mode p.s.u. included.
