THE SERVSWITCH™ FAMILY
Welcome to the ServSwitchTM Family!
Thank you for purchasing a BLACK BOX®ServSwitch™Brand CAT5 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 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!

CHAPTER 1: Quick Start Guide
1. Quick Start Guide
When you configure the ServSwitch™ Brand CAT5 KVM Micro Extender, you only
need to answer two questions:
• How far will the CAT5 cabling run between the Extender’s Local and Remote
Units? If will be 25 m (80 ft.) or less, you don’t need to set anything. If it will be
25 to 50 m (80 to 160 ft.), move DIP switch 1 on the bottom of the Remote
Unit to the DOWN (ON) setting.
• Do you need the Scroll Lock key for anything? If not, you don’t need to set
anything; you’ll be able to press Scroll Lock to reset the Extender. If you need
Scroll Lock to control your hardware or software, move DIP switch 2 on the
bottom of the Remote Unit to the DOWN (ON) setting.
To install your Extender system, refer to the illustration below. A basic
ACU3009A (Dual-Access) installation with a CPU and monitors, keyboards, and
mice is shown; ACU3001A Single-Access systems will be set up exactly the same way,
except that they won’t include the local keyboard, monitor, and mouse.
Use the included extension cable to attach the CPU to the Local Unit. Plug the
remote keyboard, monitor, mouse, and serial device directly into the Remote Unit.
In Dual-Access systems, plug the local keyboard, monitor, mouse, and serial device
directly into the Local Unit. Connect the Local and Remote Units with straight-
pinned four-pair solid-core CAT5 cable (not CAT5e, Level 6, etc.). Power the
Remote Unit with its included power supply. For more information, or if your
installation includes any KVM switches, refer to Chapter 6.

CHAPTER 3: Introduction
3. Introduction
By using the Local and Remote Units that together make up the ServSwitch™
Brand CAT5 KVM Micro Extender, you can place your VGA monitor, keyboard,
and mouse as far as 50 meters (160 ft.) from the PC’s CPU. The Local and Remote
Units are interconnected with a single industry-standard Category 5 UTP or STP 4-
pair cable. All keyboard, mouse, and video signals are fully buffered to ensure
consistent remote operation of your PC.
The Single-Access (ACU3001A) model of the Extender is designed to perform
KVM extension only. With the Dual-Access (ACU3009A) model, you can attach an
additional monitor, keyboard, and mouse to the Local Unit; the PC can then be
operated from either the local or remote user station (they share access on a “first-
come, first-served” basis—see Section 7.5).
The Micro Extender is simple to operate and works with all operating systems—
no software is required. Just connect the Units as described in Chapter 6 and
you’re ready to work!
Because the Micro Extender performs complete PS/2®keyboard and mouse
emulation, you can boot the PC without having a keyboard or mouse attached to it.
Your PC will boot even if the Extender’s Remote Unit is not powered or has no
keyboard or mouse connected to it.

14
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER
3.1 Compatibility
The ServSwitch Brand CAT5 KVM Micro Extender is designed to operate in
various environments and with a mix of hardware from different manufacturers.
During development, this product was extensively tested with a wide variety of
hardware. However, please note that it is impossible for us to guarantee that the
Micro Extender will interoperate correctly with every keyboard, mouse, monitor,
and motherboard variant currently on the market. If you suspect that you’re
having incompatibility problems, please call Black Box Technical Support.
In general, the Micro Extender is compatible with the following types of
equipment:
•CPU: IBM®PC/AT®, PS/2, and 100% compatible clones. These should be
desktop machines; laptops and docking stations are not supported.
•Monitor: VGA, SVGA, XGA, XGA-2, or RGsB (sync on green). Be aware that a
few monitors and graphics cards might not work with the “as is” Micro
Extender—at least in their factory-default settings—because they exchange
monitor IDs or VESA DDC (Display Data Channel) information. Call Black
Box Technical Support for help with “ID bit” problems. As for DDC, the
Extender supports it at the ACU3009A’s local user station but not at any
remote user station, so either (a) do not use a DDC monitor at your remote
station, or (b) go into your graphics card’s settings, turn DDC off, and
manually configure the card for your monitor(s).
•Keyboard: Standard (101- or 102-key) PS/2 type or enhanced PS/2 type (104-
or 105-key, designed for use with versions of Windows®starting with
Windows 95). Although we don’t recommend this, you might also be able to
use a PC/AT type keyboard with 5-pin DIN connectors; you’ll need adapters to
attach it and its native CPU to the Micro Extender (see the start of
Section 4.2). Some older PC/XT™ or PC/AT type autosensing keyboards
might not be compatible with the Extender. If the keyboard you want to use is
some other type or has some other type of connector, call Black Box for
technical support.
For information about keyboard typematic support, see Section 7.2.
•Mouse: Standard PS/2 type, Microsoft®IntelliMouse®compatible, or
Logitech™ 3-button PS/2 compatible mouse; the CPU should have standard
PS/2 type mouse ports. If your PC doesn’t have a PS/2 style mouse port, you’ll
need a special adapter to attach the PS/2 mouse cable to one of the PC’s serial
ports (see the start of Section 4.2). The Extender is not compatible with serial
mice or bus mice. If a mouse you want to attach is some other type or has some
other type of connector, call Black Box Technical Support.

CHAPTER 3: Introduction
3.2 Key Features
The ServSwitch Brand CAT5 KVM Micro Extender has a number of useful features
which contribute to the transparent remote operation of your PC. Some of the
more important ones are:
•Distance up to 50 m (160 ft.)
Operate your PC from the next room or all the way down the hall.
•Adjustable video equalization
Compensates for the loss of image quality caused by the signal passing through
more than 25 m (80 ft.) of cable.
•Fully buffered signals
Remote operation of the PC is consistently smooth and transparent.
•Intelligent PS/2 keyboard and mouse emulation
With this, the PC boots and operates correctly under most circumstances, and
you can freely detach and reconnect the keyboard and mouse as necessary
(the Micro Extender automatically initializes the keyboard and mouse as soon
as it detects that you’ve reattached them).
•Microsoft IntelliMouse compatibility
Use this and compatible “wheel mice” with confidence.
•Dual-Access model also supports a local station
With the Dual-Access (ACU3009A) model, you can operate the PC either
locally or remotely (but not both at the same time).
We recommend that you read the remainder of this manual before you install the
Micro Extender in order to fully familiarize yourself with the system.

• (1) Copy of this manual.
4.2 The Cables You’ll Need
If you are using the ServSwitch™ Brand CAT5 KVM Micro Extender to get greater
distance between a CPU and a VGA monitor, PS/2 keyboard, and PS/2 mouse,
your Micro Extender package should have included everything you’ll need except
for your Unit-interconnection cable. Read Sections 4.2.1, 4.2.3, and 4.2.5 carefully,
then skip ahead to Chapter 5.
If you are using the Micro Extender to get greater distance between a ServSwitch
family KVM switch and a CPU, a user station (monitor/keyboard/mouse), or a
compatible switch, you might need additional non-included cabling. Read the
relevant sections on the next few pages, from Section 4.2.1 through Section 4.2.5.
If you are using any equipment with PC/AT style connectors, you might also
need some combination of these adapters:
• To attach a CPU or KVM switch with a 5-pin DIN female keyboard
connector
to the Local Unit: A keyboard-port adapter such as product code FA211.
• To attach a CPU or KVM switch with an RS-232 serial DB9 male mouse connector
to the Local Unit
: A mouse-port adapter such as product code AC244A. (If the
mouse port is DB25 rather than DB9, you’ll also need an FA521A serial adapter .)
• To attach a keyboard or KVM switch with a 5-pin DIN male keyboard connector
to the Local or Remote Unit: A keyboard adapter such as product code FA212.

CHAPTER 4: Checklist of System Components
4.2.1 T O C ONNECT A CPU TO THE L OCAL U NIT
You’ll use the three-in-one KVM-extension cable included with the ServSwitch™
Brand CAT5 KVM Micro Extender.
4.2.2 T O C ONNECT A S ERV S WITCH F AMILY KVM S WITCH TO THE L OCAL U NIT ’ S CPU P ORT
You would do this to extend the distance you can run from the KVM switch to a
monitor, keyboard, and mouse. (You could also do this to extend the distance you
can run between two cascaded switches, but for this to work, each switch must be
either a ServSwitch Jr. or one of the ServSwitch family models with compatible
composite interfaces listed in Section 4.2.2.B.)
The Local Unit’s CPU port is the DB25 connector on the opposite end of the
Unit from the RJ-45 jack. Which cable(s) you’ll use to connect the switch to it will
depend on what type of user ports the switch model has, as detailed in the
following three subsections.
4.2.2.A Switches Whose User Ports Are a Set of Separate Interfaces
The user ports of some ServSwitch family KVM switches are a set of separate
interfaces: Each user port consists of separate interfaces/connectors for video,
keyboard, and mouse communication. At the time of this writing, some of the
important ServSwitch family models in this category are:
• ServSwitch™ Duo
• ServSwitch™ Wizard
• ServSwitch™ Wizard Pro
• ServSwitch™ Jr.
• Personal ServSwitch™
• ServSelect™
• ServSwitch™ Multi Base Unit (“local console” user port only)
To attach a user port on one of these switches to the Local Unit’s CPU port, you
can use the three-in-one KVM-extension cable included with the ServSwitch™
Brand CAT5 KVM Micro Extender.

18
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER
4.2.2.B Switches Whose User Ports Are Compatible Composite Interfaces
The user ports of some ServSwitch family KVM switches are composite (all-in-one)
interfaces that are compatible with the Local Unit’s CPU port. On these switches,
the user ports are DB25 connectors pinned out the same way as the DB25
connector on the Local Unit. At the time of this writing, some of the important
ServSwitch family models in this category are:
• ServSwitch™
• ServSwitch™ Ultra
• Matrix ServSwitch™
• ServSwitch™ Affinity
• ServManager™
• ServShare™
Order a ServSwitch-to-ServSwitch Expansion Cable (product code EHN284) to
attach this type of KVM-switch user port to the Local Unit’s CPU port.
4.2.2.C Switches Whose User Ports Are Incompatible Composite Interfaces
The HD62 female user ports on the ServSwitch™ Multi’s User Cards are composite
(all-in-one) interfaces that are not compatible with the Local Unit’s CPU port. This
doesn’t mean that they can’t be connected to the Local Unit’s CPU port; you’ll just
need slightly more complicated cabling.
Namely, you’ll need a ServSwitch Multi User Cable such as product code
KV2505, plus the three-to-one KVM-extension cable included with your Extender.
Refer to Section 6.2.2.C for a description of how this cabling fits together.

You would do this to extend the distance you can run from the KVM switch to a
CPU. (You could also do this to extend the distance you can run between two
cascaded switches, but for this to work, each switch must be one of the ServSwitch
family models with compatible composite interfaces listed in Section 4.2.4.B.)
On the Remote Unit and the Dual-Access Local Unit, the user ports are the
HD15 and 6-pin mini-DIN connectors on the opposite end of the Unit from the
RJ-45 jack. Which cable(s) you’ll use to connect the switch to it will depend on
what type of CPU ports the switch model has, as detailed in the following three
subsections.
