Chapter 2: Overview
2.0 Overview
With the DVI-D/-I CATx/Fiber KVM-Extender, you can remotely locate monitors, keyboards and mice up to 140 m (459.3 ft.)
away from your CPU over CATx, or up to 10 km (6.2 mi) with single-mode fiber.
Wherever long distances are required, e.g. airports, industrial plants, call-centers or in distributed computer centers, the DVI-D/-I
CATx/Fiber KVM-Extenders are the ideal way to remotely locate your console. We offer two families with three different types:
one family with devices for DVI-I (DVI-D/-I + VGA) and one family with USB 2.0 transparent support – CATx, multimode and
single-mode.

Chapter 2: Overview
2.1 Introduction
A CATx/Fiber KVM Extender enables you to mount a CPU in a secure rack/cabinet or data center and access it from a remote
location, up to 140 meters away. A basic KVM extension system is comprised of a local unit and a remote unit. 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 cables. Local units offer dual access, allowing the connection of a second monitor close to the computer.
A CATx/Fiber KVM Extender is used to extend the maximum distance between a CPU and a keyboard/monitor/mouse. In
addition, a KVM extender is beneficial in installations in electromagnetic hazardous environments (EMI). Regular KVM extender
cables (and extenders using traditional cables) have inherent distance limitations, and EMI interference may reduce the maximum
distance and/or reliability. With a DVI-D/-I CATx Extender system, these limitations are no longer an issue.

2.3 Features
All extenders have the following features:
• Support for DVI-D graphics cards
• Support for USB keyboards and mice (USB-HID)
NOTE: Devices with USB-HID support only keyboard and mice. It’s possible that other HIDs like touchscreens, graphics
tablets, bar-code readers or similar are supported – but that isn’t guaranteed. If you have questions, call our FREE Tech Support.
The DVI-D/-I CATx/Fiber KVM-Extender for USB-HID is not suitable for use with other USB devices like scanners, webcams, flash
drives, etc.
NOTE: The USB-HID device never supports more than two devices – keyboard and mouse or keyboard and touchscreen, etc.,
but not, for example, keyboard, mouse and touchscreen simultaneously. A hub is allowed but does not increase the number of
supported devices.
Maximum resolution: DVI-D: 1920 x 1200 @ 60 Hz over all allowed distances all resolutions below of 1600 x 1200 with refresh
rates of at least 75 Hz.
• Supporting 16-bit/24-bit auto switching or fixed 24-bit color depth (user selectable)
• Status indicator LEDs on each device.
• Small footprint chassis.
• CPU cables and adapters included.
• Rackmount kit available.
ACS4002A-R2 family:
• Additional USB 2.0 transparent high-speed transmission (requiring an additional CATx cable or fiber pair). Four devices can be
attached directly at the Remote Unit—more by using regular USB hubs.
ACS4004A-R2 family:

Chapter 2: Overview
2.5 How to Use This Guide
This guide describes the installation and configuration of the DVI-D/-I CATx/Fiber – Extender Series. Although the connection and
operation of the system is relatively straightforward, you should consider the following before getting started:
Connection and Compatibility
If you have purchased an Extender Kit, this will contain all the cables required to connect the local unit to your PC or KVM switch.
Please see also: 3.1 What‘s Included.
For information about connection and installation, see 3.2 Interconnection Cable Requirements.
DDC information
Normally it is not necessary to make any adjustments to the DVI-D/-I CATx/Fiber- Extender. However, in some circumstances, it
may be necessary to redefine the source of DDC information for the CPU. By default, the DVI-D/-I CATx/Fiber KVM-Extender uses
its own internal DDC table. If this setting does not satisfy your requirements, the DDC table can either be switched to the locally
attached screen or could be downloaded from a remotely located screen and stored in the internal DDC table.
To modify the DDC setup, see 4.0 Service Setup.
Selecting the moment of switching to the next frame
The transmission of screen data is not synchronous to the screen change of the graphics card. Normally, the transmission is
terminated during displaying a frame on the screen. If the device switches to the new frame during the displaying period of the
old frame (somewhere on the screen), it’s possible, and that you can see horizontal screen breaks in the moment of switching
(default). On the other hand, the device must idle, until the actual frame is displayed completely (until VSYNC) -> the number of
frames per second transmitted sinks.
To modify the switching behavior, see 4.0 Service Setup.
Selection of color reduction for transfer acceleration
You can select, whether always 24-bit colors (=full color depth) are transmitted or whether the compression algorithm
automatically switches between 16- and 24-bit colors to accelerate the data transfer (default). Normally the difference between
24-bit and 16-bit is not recognizable but under some special circumstances, e.g. in photo processing installations, there might be
disturbing color aberrations. However, the automatic color switching enhances the frame count transmitted per second; fixed
24-bit color depth gives smooth color grades under all circumstances. Choose the one that’s best for your application.
To modify the color depth, see 4.0 Service Setup.

Chapter 3: Installation
3.0 Installation
For first-time users, we recommend that you carry out a test placement, confined to a single room, before doing a full
installation. This will enable you to identify and solve any cabling problems, and experiment with the KVM extender system more
easily.
3.1 What‘s included
All:
• DVI-D/-I CATx/Fiber KVM-Extender pair (local and remote units)
• (2) US power cords
• (2) 5-VDC power supplies
• 6-ft. (1.8-m) USB cable
• 6-ft. (1.8-m) DVI-D video cable
• User‘s manual with quick-install guide
ACS4004A-R2 family (also includes):
• 6-ft. (1.8-m) USB cable
ACS4011A-R2 family (also includes):
• 6-ft. (1.8-m) VGA-to-DVI-D video cable

ACS4002A-R2
Chapter 3: Installation
3.2 Interconnection Cable Requirements
To connect the Local and Remote units you will need:
• USB: Connect the supplied USB CPU cable to your CPU (KVM switch, etc.). Make sure that the connection is tension-free.
• DVI: Connect the supplied DVI CPU cable to your CPU (KVM switch, etc.). Make sure that the connection is tension-free.
• VGA/DVI: Connect the supplied VGA to DVI CPU cable to your CPU (KVM, switch, etc.). Make sure that the connection is
tension-free.
• CATx cable: Recommended cable: S/UTP (CATx) according EIA/TIA 56A, TSB 36 or Digital STP 17-03170. Four-pair 24 AWG
connection according EIA/TIA 568A (10BASE-T). Use of cables from a higher category (CAT5e, CAT6, CAT7) is possible.
NOTE: The use of unshielded CATx Cable is possible, but because of the higher electromagnetic noise/sensitivity the device class
may not be reached.
NOTE: The use of flexible cables (patch cable) 26 or 27 AWG is possible. Because of the higher loss of the stranded cables, the
maximum distance is reduced to approximately half the value of solid cables.
NOTE: 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 CATx link interface (RJ-45) to any other products, especially telecommunications or network equipment.
• Fiber cable: Two strands of fiber are required for single-head devices, four strands for dual-head devices.
NOTE: The maximum distance will depend on device type and on fiber type used.
Recommended cables:
ACSxxxxA-MM: 50-µ multimode distance approximately 1312 ft. (400 m)
ACSxxxxA-MM: 62.5-µ multimode distance approximately 656 ft. (200 m)
ACSxxxxA-SM: Single-mode distance approximately 32,808 ft. (10 km)
A point-to-point connection is required. You can have one or more patch panels in the line. You can’t have a connection from the
fiber link interface (LC) to any other products, especially telecommunications or network equipment.
Single-mode devices often work well on multimode fibers, but the reverse isn’t true. In addition, however, single-mode devices
on multimode fibers may possibly double the distance on multimode fibers. There is no guarantee of this, and users are asked to
perform tests within their own environments.
• Power supply: Connect the supplied 5-VDC power supplies to the plug terminal on the rear of both local and remote units.
