REPEATER/CROSS- REPEATER
Rev. : 09/25/2012 1
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

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.
2.2 Glossary
The following terms are used in this guide:
CATx Any Category 5, 5e, 6 or higher cable, solid wires type AWG24.
Fiber Singlemode or Multimode fiber cable.
Singlemode 9µ Singlemode-fiber cable
Multimode 62,5µ Multimode- or
50µ Multimode-fiber cable
KVM Keyboard, Video and Mouse.

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.

•User manual (Quick Setup)
If anything is missing, please contact Technical Support (see Appendix F – Calling
Technical Support).

INSTALLATION
Rev. : 09/25/2012 13
3.2 Interconnection Cable Requirements
To install the Repeater/Cross- Repeater you will need:
•CATx Cable: Recommended cable: S/UTP (Cat5) according EIA/TIA 56A, TSB 36 or
Digital STP 17-03170. Four pairs AWG 24. connection according EIA/TIA 568A
(10BaseT). Use of cables from a higher category (Cat5e, Cat6, Cat7) is possible..
The use of unshielded CATx Cable is possible, because of
the higher electromagnetic noise/sensitivity the device class
may not be reached, the compliance with CE regulations is
not longer guaranteed.
The use of flexible Cables (Patch cable) Type AWG26/8 is possible.
Because of the higher loss of the stranded cables, the maximum distance is
reduced to app. half the value of solid cables.
•Fiber Cable: Two strands of fiber are required for singlehead devices, four strands for
Dualhead devices.
Please note, that the allowed distance will depend on device type AND on
used fiber type.
•Recommended cables:
Multimode type 50/125µ allowed distance app. 400m (1,300ft)
Multimode type 62.5/125µ allowed distance app. 200m (650ft)
Singlemode type 9/125µ allowed distance app. 10km (32,750ft)
A point to point connection is required. Having one or more patch panels
in the line is possible and allowed. Not allowed is a connection from the
Fiber link interface (LC) to any other products, especially
telecommunications or network equipment.
Our experiences show, that Singlemode devices regularly work well on
Multimode Fibers where vice versa it will never do. In addition we found,
that Singlemode devices on Multimode fibers may extend the allowed
distance on Multimode fibers to twice the regular length. Anyway this
cannot be guaranteed and must be evaluated by the end-user at his own
expense.
•Power Supply: Connect the supplied 5V/DC power supplies to the Plug terminal on the
rear of both local and remote units.

If you have bought a Cross Repeater, your device will have two CATx
connectors but only one fiber connector. Possibly you have to swap the
fiber GBIC from one port to the other to make the unit working properly.
To do this, please refer to installation instruction on page 19.
If you have bought a Dual Cross Repeater, your device will have two
CATx connectors and two fiber connectors. The units are marked as
„Local“ or „Remote“. For a correct installation, please refer to
installation instruction on page 19. If you want to upgrade a Cross
Repeater to Dual Cross Repeater, you need to reconfigure the jumper
settings.To do this, please refer to Setup at the Repeater/Cross- Repeater
on page 18.
4. Connect the 5V power supply unit to power the unit.
Only use the power supply originally supplied with this
equipment or a manufacturer-approved replacement.

connected to the fiber connector A of the second Repeater. The Remote Unit is connected via
CATx (Fiber) connector B.
Reconfiguration of a Cross Repeater from „Local“ to „Remote“
or vice versa
The „Local“ device must carry the fiber GBIC in the connector B, the „Remote“ device in the
connector A. If the GBICs in your devices are plugged incorrect, you may alter the
configuration easily:
•flap the shackle at the GBIC downwards
•now pull the GBIC, using the shackle, out of the cage
•plug the GBIC with soft force into the other cage until it snaps into place
•flap the shackle at the GBIC upwards to lock the GBIC
Do not try to pull the GBIC out of the cage while the shackle
remains in the lock position (not flapped downwards). As long
as the shackle is flapped upwards, the GBIC is locked. Rough
pulling the GBIC out of the cage without flapping the shackle
downwards may result in damages at the GBIC and/or at the
device.
