THE SERVSWITCH™ FAMILY
Welcome to the ServSwitchTM Family!
Thank you for purchasing a BLACK BOX®ServSwitch™Brand KVM switch! We
appreciate your business, and we think you’ll appreciate the many ways that your
new ServSwitch keyboard/video/mouse switch will save you money, time, and
effort.
That’s because our ServSwitch family is all about breaking away from the
traditional, expensive model of computer management. You know, the one-size-
fits-all-even-if-it-doesn’t model that says, “One computer gets one user station, no
more, no less.” Why not a single user station (monitor, keyboard, and mouse) for
multiple computers—even computers of different platforms? Why not a pair of
user stations, each of which can control multiple computers? Why not multiple
user stations for the same computer?
With our ServSwitch products, there’s no reason why not. We carry a broad line
of robust solutions for all these applications. Do you have just two PCs and need an
economical alternative to keeping two monitors, keyboards, and mice on your
desk? Or do you need to share dozens of computers, including a mix of IBM®PC,
RS/6000®, Apple®Macintosh®, Sun Microsystems®, and SGI®compatibles among
multiple users with different access levels? Does your switch have to sit solidly on a
worktable and use regular everyday cables? Or does it have to be mounted in an
equipment rack and use convenient many-to-one cables? No matter how large or
small your setup is, no matter how simple or how complex, we’re confident we
have a ServSwitch system that’s just right for you.
The ServSwitch™family from Black Box—the one-stop answer for all your KVM-
switching needs!

SERVSWITCH™ WIZARD DVI
2. Introduction
The ServSwitch™ Wizard DVI is a high-performance keyboard-, monitor-, and
mouse-sharing device that supports a wide range of IBM®PC compatible hardware
and software platforms, including some high-end IBM PS/2®compatible
computers (IBM RS/6000®, Compaq®Alpha®, and SGI™). It is specifically
designed to support DVI (Digital Visual Interface) video. It comes in several
models:
• The 2-Port (product code KV1002A) and 4-Port (KV1004A) Single-Head
models support DVI video cards with a single video output.
• The 2-Port (KV1022A) and 4-Port (KV1024A) Dual-Head models support DVI
video cards with up to two video outputs. They also support user stations with
either dual monitors or a single monitor that can composite dual video feeds
into a single image.
• The 2-Port (KV1042A) and 4-Port (KV1044A) Quad-Head models support DVI
video cards with up to four video outputs. They also support user stations with
either as many as four monitors or a single monitor that can composite as
many as four video feeds into a single image.
2.1 Features and Benefits
Here are some of the useful features of the ServSwitch Wizard DVI and some of the
ways those features benefit you:
•
You can use a single keyboard, mouse, and one to four monitors or monitor
feeds to control multiple computer CPUs that output DVI video.
• Supports DVI monitors at resolutions up to 1600 x 1200 pixels and refresh
rates up to 60 Hz. Its maximum pixel frequency is 165 MHz per port—the
maximum single-link bandwidth in the DVI specification—so higher refresh
rates can be supported for lower resolutions.
• When used with video cards and monitors that can transmit and receive
multiple parts of the same image on multiple video heads, the Dual-Head
models can support resolutions up to 2400 x 1600, and the Quad-Head models
can support resolutions up to 3200 x 2400.
• Supports IBM RS/6000\, Compaq Alpha, and SGI computers that output DVI
video.
• Compatible with all popular operating systems for the IBM PC.

13
CHAPTER 2: Introduction
• Continuous keyboard and mouse emulation on all ports ensures problem-free
computer bootup. And because all ports are active simultaneously, all attached
CPUs can be booted at the same time.
• Automatically detects attached hardware.
• The Dual- and Quad-Head models come with a power supply, but the Single-
Head models can usually draw all the power they need from the attached
CPUs. For demanding applications with cascading and/or high-end video, an
optional power supply (product code PS649) is available for the Single-Head
models.
• Local channel switching using its front-panel pushbutton, a keyboard hotkey
sequence, or a three-button mouse.
• Remote channel switching through its RS-232 serial port, using its convenient
optional Remote-Control Module (RCM) or some other device.
•
Intelligent switching: You can scan/switch between all ports or just the active ones.
• Flash-upgradable for easy on-site firmware upgrades.
• Video channels support DDC2B Display Data Channel signaling and DVI Hot
Plug Detect.
• Can be cascaded to control a large number of CPUs.
• Can be synchronized to control CPUs with more than four video outputs.
• Password security prevents unauthorized use.
• Stores its configuration in persistent EEPROM memory.
• Restores keyboard and mouse states automatically when channel is changed.
• CPUs can have PS/2 keyboard ports and either PS/2 or RS-232 mouse ports.
• Supports keyboard modes 1, 2, and 3, as well as both “prompt” and “stream”
mouse modes, for maximum compatibility.
• Support for Microsoft®IntelliMouse®and many other “wheel mice.”
• Mouse-restoration functions that make it possible to hot-plug certain systems.
• If problems occur, you can soft-reset the keyboard, the mouse, or the Wizard
DVI itself without disconnecting any devices.

14
SERVSWITCH™ WIZARD DVI
• Includes screen-blank, autoscan, and variable-hotkey options.
• Front-panel 7-segment LED shows you how the Wizard DVI is operating.
• Metal enclosure for good shielding and video quality.
2.2 The Complete Package
The only other thing that comes with the Single-Head (KV1002A and KV1004A)
models of the ServSwitch Wizard DVI is a users’ manual. All other models also
come with a power supply. (We don’t include a power supply with the Single-Head
models because most applications for those models don’t require one. If you need
a power supply for a Single-Head Wizard DVI, it can be purchased separately as
product code PS649.)
The only other things that come with the Wizard’s optional Remote-Control
Module (“RCM” for short, the KV6REM series of product codes—see Section 5.2)
are VELCRO®mounting strips.

CHAPTER 2: Introduction
2.4 Safety Concerns
As you prepare to install the ServSwitch Wizard DVI, please keep these things in
mind:
• The Wizard DVI is for use in dry, oil-free indoor environments only.
•Donot attempt to fix the Wizard DVI yourself.
• Follow all warnings and instructions marked on the Wizard DVI, its power
supply (if you’re using one), and any other accessories.
• If you’ll be using a power supply with the Wizard DVI (optional with the
Single-Head models, required for other models):
–Warning: The Wizard DVI’s power-supply transformer contains no user-
serviceable parts, but it does contain “live” parts capable of delivering
hazardous electric shocks—do not attempt to dismantle it!
– Make sure that the total current rating of the devices plugged into the AC
outlet that’s supplying the Wizard DVI is not greater than the outlet’s rated
current capacity.
– If you use an extension cord with the power supply, make sure that the total
current rating of the devices plugged into the extension cord is not greater
than the cord’s rated current capacity.
–Donot continue to use the Wizard DVI’s power supply if the supply’s
transformer case becomes damaged, cracked, or broken, or if you suspect
that the power supply isn’t operating properly.
– If the Wizard DVI’s power supply stops working, replace it with a
manufacturer-approved power supply of the same type only.

SERVSWITCH™ WIZARD DVI
3. Installation
3.1 What You Will Need
You’ll need these things before you can install your ServSwitch Wizard DVI:
•
Cables to connect the ServSwitch Wizard DVI to the keyboard, video, and mouse
ports of each of your computers. (You don’t need to connect mouse cabling to
a CPU if you’re not using a mouse with that CPU.) If you’ll be installing cascaded
or synchronized Wizard DVIs, you’ll also need cables to interconnect the Wizard
DVIs. You’ll need adapters to connect the Wizard DVI to any CPUs’ RS-232
serial mouse ports. For cable and adapter specifications, see the Appendix.
• A monitor with one or more DVI connectors that will work when connected
directly to each of your computers.
• A standard PS/2 style keyboard.
• A PS/2 style two- or three-button Microsoft or Logitech™ compatible mouse
or a Microsoft IntelliMouse or IntelliMouse Explorer compatible mouse. If you
want to use the mouse to switch channels on the ServSwitch Wizard DVI, you’ll
need a three-button mouse or an IntelliMouse. (The Wizard DVI supports
other IntelliMouse compatible “Internet mice”—fitted with a wheel or other
scrolling control, and sometimes additional buttons—including several models
by Logitech and Genius™.)
All the mouse connections from ServSwitch Wizard DVI to the attached
computers support either PS/2 mouse ports or RS-232 serial mouse ports. The
Wizard DVI automatically converts PS/2 mouse data and commands to serial-
mouse data and commands, but you’ll still need the appropriate adapter—
product code FA314—to connect the Wizard DVI to a PC with a serial mouse
port. See Section A.2 in the Appendix.
The Wizard DVI will operate without a mouse connected if you don’t want
to use one.
• A suitable mouse driver for your PCs (if you’re using a mouse). Supported
types are:
– PS/2 or RS-232 two-button mouse driver by any manufacturer.
– Microsoft mouse drivers, including those for the IntelliMouse. (You might
be able to use other drivers with IntelliMouse compatible data formats, but
these might not work—trial-and-error testing might be necessary.)
– Logitech mouse drivers, including those for two-button, three-button, and
wheel mice.

19
CHAPTER 3: Installation
3.2 Placement
The ServSwitch Wizard DVI should be placed on a desktop or shelf near your
monitor and peripherals. You can use the optional Remote-Control Module if you
want to put a Wizard DVI farther from your monitor and peripherals.
3.3 Connecting Your Equipment
IMPORTANT NOTE
Not all DVI video cards properly detect the user-station monitor if their
CPU is hot-plugged into the Wizard DVI, or if their CPU is not able to
communicate directly with the monitor when the CPU is powered up.
This can cause DVI cards not to output any video at all. For this reason,
the Wizard DVI’s factory-default behavior is to automatically switch to
the CPU port of any attached CPU that it detects is being booted.
However, if you boot up all of your CPUs at the same time, some of
them might still not be able to detect the monitor properly. To make sure
that your video cards detect the monitor and configure themselves
correctly, all CPUs should be off when you attach them, and you should
power them up one by one, waiting a few seconds between each boot.
If your DVI cards are smart enough that this “bootup autoswitching”
is unnecessary, you can turn it off. See Section 4.2.1.
NOTES
When you connect devices to Wizard DVIs’ “control ports” and “CPU
ports,” refer to Figures 2-2 and 2-3 in Section 2.3 to see where these
ports are.
Any unused CPU-port or control-port connectors on a ServSwitch
Wizard DVI can be left vacant.
Most ServSwitch Wizard DVI applications will involve a keyboard, mouse, one to
four monitors, and two to four computer CPUs attached to a single Wizard DVI. If
that describes what you want to do, follow the procedure in Section 3.3.1.
If you want to switch between more than four CPUs, you’ll need multiple cascaded
Wizard DVIs to connect them. Follow the procedure in Section 3.3.2.
If your CPUs have between five and eight DVI outputs, or if they have
simultaneous DVI and analog video outputs, you will need multiple synchronized
Wizard DVIs or other ServSwitch Wizard models to switch between the CPUs.
Follow the procedure in Section 3.3.3.NOTE
It is theoretically possible to install a synchronized cascade, or to
connect CPUs with more than eight DVI outputs, but the cabling would
be complicated. If you need to switch between large numbers of
computers with large numbers of multiple video outputs, please call
Black Box Technical Support to discuss your application.
