THE SERVSWITCH
FAMILY
Welcome to the ServSwitch™ Family!
Thank you for purchasing a BLACK BOX® ServSwitch™ Brand PS/2 Micro 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!
This manual will tell you all about your new ServSwitch™ Brand PS/2 Micro Extender,
including how to install, operate, and troubleshoot it. For an introduction to the Extender, see

How to Use This Guide
This guide describes the installation and configuration of the ServSwitch Brand PS/2 Micro
Extender Series. Although the connection and operation of the system is relatively
straightforward, you should consider the following before getting started:
Connection & 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. The Remote console (keyboard, monitor and mouse)
and any audio and serial equipment connects directly to the Remote unit.
If you have purchased a Remote Unit, ensure that it is compatible with your Local unit (see
Compatibility, page 16).
For information about connection and installation, see Installation, page 19.
Interconnection Cable
You will need CATx (any category 5, 5e, 6 or higher) cable, terminated with RJ45 plugs, to
connect the Local and Remote units (see Interconnection Cable Requirements, page 20).
Adjusting Video
Video signals become distorted when transmitted over CATx cables. To get the best from
your extender system, it is essential that you adjust the Remote unit to optimize the video
image quality:
•
For experienced users, there is a Quick Setup section at the start of this guide (see page
10).
•
For the full procedure, see Remote Unit Configuration & Operation, page 28.

SERVSWITCH
3.2
PS/2 MICRO EXTENDER FAMILY
Interconnection Cable Requirements
To connect the Local and Remote units you will need CATx (any category 5, 5e, 6 or higher)
cable terminated with RJ45 plugs.
Interconnect cables must be solid-core type. Stranded patch cable will give poor results over
longer distances. The pairing of the cable and pinning of its connectors should normally be in
accordance with EIA-568B (see Appendix D: Cable Pinning, page 46).
One CATx cable is required for each video channel.
•
The Primary interconnect cable connects INTERCONNECT Port 1 on the Local and
Remote units. This carries the main video channel and all data (plus audio/serial).
•
The Secondary CATx cable (connected to INTERCONNECT Port 2) carries the second
video channel.
In order to send Keyboard, Mouse, Audio and Serial signals to the PC, the
Primary interconnect must be connected.
The Primary interconnect does not have to be connected in order to use the
keyboard attached to the Remote unit for setup. However, if the Primary
interconnect is disconnected, the keyboard cannot be used for configuration for 15
seconds after disconnection (to maintain data integrity).
With some cables, video performance may be improved by using a crossover patch
cable at each end or an alternative RJ45 pin-out (see Appendix D: Cable Pinning,
page 46).

Remote Unit Configuration &
Operation
This section describes how to optimize the video signal, configure the Extender system and
operate the Remote unit.
For details about flash upgrading and external configuration see Appendix C: Remote Unit:
Flash Upgrading & External Configuration, page 45.
For more information about serial/audio port operation, see Appendix E: Audio/Serial
Ports, page 47.
4.1
Command Mode
During normal use, the Remote console keyboard functions in the usual manner. However, by
using a specific ‘hot’ key sequence, you can set the keyboard into a Command Mode. From
this, you can use various keys and key combinations to tune the video signal and generally
configure the extender system.
To enter Command Mode:
1.
Ensure that you have installed and powered up the system according to the instructions
in Section 3.
2.
Press the following key combination on the Remote keyboard:
<Left Control> + <Left Shift> + <F10>
From Command Mode you can use one or more of the ‘hot’ key sequences shown on page 11
to configure the system. The next section gives a full description of the video optimization
procedure.
To exit Command Mode:
•
Press <Esc> to exit Command Mode and save the configuration settings, or
•
Press <Left Control> + <Esc> to exit Command Mode without saving changes made in
the current session.
The Remote unit automatically exits Command Mode after 30 sec of
inactivity, saves all settings to EEPROM and returns normal function to
the keyboard.

REMOTE UNIT CONFIGURATION & OPERATION
Status LEDs in Command Mode
In Command Mode, the Remote unit:
•
Illuminates the yellow Interconnect 1 LED continuously (see Figure 5).
Note. The Yellow LED on Interconnect 2 is not lit.
•
Flashes the status LEDs (Num Lock, Caps Lock, Scroll Lock) on the connected
keyboard to indicate the selected video channel (to which adjustments will be applied).

PS/2 MICRO EXTENDER FAMILY
Adjusting Video
PS/2 Micro Extender Remote units incorporate video equalization circuitry, allowing you to
compensate for the loss in image quality that occurs when video signals are transmitted along
CATx cables. At the factory, Remote units are configured to optimize the video signals for
Interconnect cables up to 75ft (25m) in length.
If you intend to use cables of 75–150ft (25-50m) in length:
1.
Ensure that you have installed and powered up the system according to the instructions
in Section 3.
2.
Enter Command Mode by pressing the following key combination on the Remote
console keyboard:
3.
4.
<Left Control> + <Left Shift> + <F10>
By default, both channels are selected for adjustment and this is indicated by slow
flashing of the keyboard status LEDs (Num Lock, Caps Lock, Scroll Lock). If you want
to select a single channel press the corresponding numbered key:
Video channel
Command
Keyboard Status LED action
Channel 1
<1>
Single flashes
Channel 2
<2>
Double flashes
Both channels
<0> (default)
Slow single flashes
Press the following key combination to change the video equalization setting:
<Left Control> + <E>
Note: This command toggles the video equalization setting; repeat the procedure to
revert to the original setting for a shorter interconnection cable length [<75ft (25m)].
5.
If you are using one or more flat panel monitors in the Remote console, carry out
auto-adjustment as described in the monitor’s documentation. Sometimes manual
adjust of clock and/or phase is also required for optimum results and minimization
of jitter.
Technical Note: This video compensation does not correct color
separation (skew). Although skew can be an issue on some CATx
cables, it would not normally be observed on cables <150ft (50m).
Even so, we still recommend the use of low skew cables with PS/2
Micro Extenders. You can check whether skew is a problem in your
system by viewing the test card at:

REMOTE UNIT CONFIGURATION & OPERATION
4.3
Other Remote Configuration &
Operation Options
The ServSwitch Brand PS/2 KVM Micro Extender Series has additional commands to reset
the keyboard and mouse, to restore the factory default configuration, change DDC settings,
and to initiate and control a Private mode session (Dual Access models only).
Command
Key Sequence
Reset Mouse and Keyboard
<F1>
Resets the Remote console’s keyboard and mouse and then automatically exits Command
Mode. You may need to do this if you have hot-plugged a keyboard or mouse and it has not
initialized correctly.
Mouse Recovery
<F3>
Use this command if you experience erratic movement of the mouse pointer or you have lost
mouse movement after hot plugging the Local unit into the CPU. In the case of erratic
mouse movement, you may need to enter the command a number of times to re-synchronize
the mouse signal. Alternatively, stop moving the mouse for a few seconds and the operating
system’s mouse drivers may automatically re-synchronize the signal. If the Local unit has
been hot-plugged, this command will issue a request to the OS to initialize the mouse. Use
this command with care.
Set Extender To Default State
<Left Control> + <F9>
Sets ALL extender settings (video, configuration & DDC) back to the factory defaults and
then exits Command Mode.
Toggle Remote Unit Private Mode
<Scroll Lock>
Use this command to begin or end a Private Mode session at the Remote console (see page
32).
Toggle Local Video Blanking State
<Left Control> + <Scroll Lock>
Use this command to determine whether the Local console monitor will be blanked (default
setting) or enabled during a Private mode session at the Remote console.
Disable DDC Emulation
<Left Control> + <F2>
By default, the Local unit provides DDC emulation on both video channels. Use this
command to disable DDC emulation (see page 32).
Enable DDC Emulation
<F2>
Use this command to restore DDC emulation.
Transfer DDC to Local Unit
<Left Control> + <D>
Read DDC from monitor connected to Remote Unit video channel 1 and apply to selected
video channels in Local Unit (see page 33).
31
SERVSWITCH
PS/2 MICRO EXTENDER FAMILY
Private Mode
On dual access systems, a user at one console can lock out the other console by triggering a
‘Private Mode’ function. This prevents the other console from being used even if the twosecond inactivity timeout period expires.
To indicate that the Private Mode session is active, the extender system:
•
Slowly flashes the Scroll Lock LED on the user’s keyboard.
•
Illuminates all three LEDs on the other console’s keyboard.
•
Locks the other console’s keyboard and mouse.
•
Displays a blank image on the other console’s monitor. If you want the other console
monitor(s) to remain active during Private Mode sessions, use the Toggle Video
Blanking State command.
To cancel the Private Mode, enter Command Mode again and press <Scroll Lock>. This
command also closes Command Mode.
DDC Emulation
Modern graphics cards use VESA DDC (Display Data Channel) to identify the capabilities of
connected monitors. Some cards will not operate correctly unless they communicate with a
DDC-enabled monitor.
By default, a PS/2 Micro Extender Local Unit emulates a universal monitor (on both
channels) and reports that it is capable of all standard screen resolutions and refresh rates.
This ensures that the vast majority of graphics cards and monitors should operate correctly
with the extender system.
The DDC emulation can be optionally disabled but this would only be required in special
applications.
It is also possible that the default DDC emulation may not report a non-standard graphics
mode, for example, if an HDTV monitor is connected. In this case, the DDC from the remote
monitor(s) may be read and stored in the Local Unit using the Transfer DDC command (see
page 33).
In addition, the default DDC emulation is flash-upgradeable (see page 45).
Always reboot Windows after adjusting a DDC parameter.
32
REMOTE UNIT CONFIGURATION & OPERATION
Transferring DDC Information
To support non-standard screen settings or other features, it is possible to read and store DDC
information into the Local Unit directly from the monitors connected to the Remote Unit.
You only need to carry out this procedure once; the Extender Units store the DDC
information in non-volatile memory and restore it at power-up.
1.
Ensure that you have installed and powered up the system according to the instructions
in Section 3.
2.
Connect the monitor to the ‘monitor 1’ socket on the Remote Unit (see Figure 4).
3.
Enter Command mode (see page 28).
4.
If you want to apply the monitor’s DDC settings to BOTH video channels, continue to
step 6.
5.
Select the video channel to which you want to apply the DDC settings (see page 30) by
pressing either <1> or <2>.
6.
Press the key combination:
<Left Control> + <D>
7.
The DDC information is read from the monitor and applied to the selected video
channel(s) in the Local unit. This may take a few seconds. The Remote console
keyboard LEDs flash twice to indicate a successful transfer.
Always reboot Windows after adjusting a DDC parameter.

Local Unit Operation
5.1
Overview
For more information about serial/audio port operation, see Appendix E: Audio/Serial
Ports, page 47.
Keyboard and Mouse Emulation
Local units have keyboard and mouse emulation. The attached PC operates normally without
requiring a keyboard or mouse to be attached to either the Remote or Local units (in the case
of a dual access system). You can therefore replace any keyboard or mouse attached to the
extender system without disrupting the operation of the computer.
Power
Local units may require an external 5V PSU (PSU1006E):
•
For video only applications.
•
If the PC cannot provide sufficient power through the keyboard connection.
5.2
Dual Access Systems
ACU3209A and ACU3228A models offer dual access from consoles at both Remote and
Local units. This operates on a first-come, first-served basis. When one console is in use, the
system blocks out the other console until there is no keyboard or mouse use at the active
console for two seconds. Both monitors show the current activity on the computer
irrespective of which console is in use.
Only Reset and Private Mode commands are available at the Local unit. If you want to
configure the Extender system (for example, change DDC emulation) or tune the video
signal, see page 28; these commands can only be issued from the Remote console.
To enter these commands:
1.
Press and release the initial ‘hot’ key sequence.
2.
<Left Control> + <Left Shift> + <F10>
Press and release the command key.
34
LOCAL UNIT OPERATION
Local Console Commands
After pressing the initial ‘hot’ key sequence (<Left Control> + <Scroll Lock> + <F10>) on
the Local keyboard, you can issue a number of commands by pressing additional keys. These
commands allow you to control a Private mode session at the Local console, reset the
keyboard and mouse or restore the Local Unit’s factory default settings.
Command
Key Sequence
Toggle Local Unit Private Mode

Troubleshooting
6.1
Video
The image is not sharp, or is badly smeared.
Have you adjusted the video equalization? Follow the instructions on page 30.
Check the Interconnect cable between the Remote and Local units. Is it of the
recommended type (see page 20)? Is it intact along its entire length and securely
connected at both ends? Is it wired correctly (see page 30)?
Ensure that all video connections throughout the system are attached securely.
Are you using an LCD panel? You need to adjust its clock and/or phase.
Colors appear to be separated and there are colored borders on text and icons.
Check the Interconnect cable between the Remote and Local units. Is it a
recommended ‘low skew’ type (see page 20)? Is it intact along its entire length and
securely connected at both ends? Is it wired correctly (see page 46)?
You can check whether skew is a problem in your system by viewing the test card
at: http://www.blackbox.com/tech_support/ts_upgrades/ts_ss.html.
I only need video extension – not keyboard or mouse - but I can’t get a picture.
Have you powered the Local unit? The Local unit gets its power from the CPU
through the keyboard connection and it will not operate without it. Use an external
5V PSU as described on page 34.
The monitor sometimes goes blank for a second or two.
Check that the interconnect cable is not routed near power lines or other sources of
electrical interference. Use shielded STP/FTP cable instead of UTP cable and
ensure the shield connection is maintained between the Extender units.
Check system grounding.
If this is a persistent problem, contact Technical Support.
The PC won’t boot into the correct graphics mode.
Check that DDC Emulation is enabled (see page 32). If you are using a nonstandard resolution, transfer the monitor’s DDC information to the Local Unit (see
page 33).
36
TROUBLESHOOTING
Jitter is evident on video.
Adjust the clock and/or phase on your flat-panel. Contact Technical Support if this
fails to improve the situation.
Are you testing a system using a coiled drum of CATx cable? Try uncoiling the
cable. If this solves the video jitter, you should not have a problem after full
installation.
The image is not stable and is blanking regularly.
Re-power the Remote unit.
Can the extender be used with RGB video?
Yes.
6.2
Keyboard & Mouse
When I am typing, I get wrong or missing characters on the screen.
Your keyboard may be in the wrong mode. Use the appropriate commands to reset
the keyboard and mouse as described in the sections covering Local and Remote
operation.
The PC comes up with ‘keyboard error’.
Press <F1> or <ESC>. If the keyboard now operates correctly, you need to adjust
the BIOS setup to disable keyboard testing during booting.
The system does not detect a PS/2 mouse.
If connecting the Local unit to a live system, connect the mouse cable to the CPU
before keyboard connection to ensure the mouse is enabled correctly.
Issue the Mouse Recovery command.
Check that the mouse cable is connected properly and securely. Reboot the system.
The mouse pointer moves erratically.
Reset the keyboard and mouse.
Issue the Mouse Recovery command up to three times.
Ensure that you have the latest driver for your mouse.
If you are using the extender with a KVM switch, command the switch to reset the
mouse.
Quit and restart the application. Reboot the PC.
37
SERVSWITCH
PS/2 MICRO EXTENDER FAMILY
When I ‘hot-plug’ the Local unit, the mouse no longer moves.
When connecting the Local unit to a live system, connect the mouse cable to the
CPU before keyboard connection to ensure the mouse is enabled.
Try issuing the Mouse Recovery command.
Some of the mouse buttons don’t work.
The PS/2 Micro Extender units support standard 2/3-button mice (with or without a
wheel). Additional buttons will not operate.
I have an enhanced keyboard with extra keys and indicators. Everything works apart from
these additional features.
As standard, the extender only emulates a generic PS/2 keyboard. To support other
keyboards (or cascaded KVM switches), special firmware offering a transparent
mode may be required. Please contact Technical Support to discuss your
application.
6.3
Audio
The audio is very quiet.
The audio I/O is line-level and requires amplified speakers and connection to
devices providing line-level I/O.
The audio is loud but distorted.
Check that the audio input is not greater than line level (4V peak-to-peak). The
KVM extender accepts line-level audio input only.
The microphone output is barely audible.
See Appendix E: Audio/Serial Ports, page 47.
6.4
Serial
My serial device does not function.
The extender supports serial devices at data rates not exceeding 19.2K Baud
(although 38.4K operation might be possible with certain equipment).
Check the type of flow control used by the device and CPU. The extender supports
RTS, CTS, DTR, and DSR. Some systems may require a wiring adapter to transfer
RI and DCD.
Attach the device directly to the serial port on the PC and test whether the problem
is a PC or extender problem.
Some serial devices cannot be hot-plugged. Try connecting the device to a powered
Remote unit prior to booting the system.
38
TROUBLESHOOTING
6.5
General Questions
Is it possible to use a cable length longer than 150ft (50m)?
It might be possible to use a cable of up to 300ft (100m) at lower resolutions.
However, we do not recommend this and cannot guarantee the video quality.
Can extenders be daisy chained?
In certain circumstances, it is possible to cascade extenders, though we do not
recommend doing so. Careful consideration needs to be given to extender setup,
and the electrical environment. If you plan to cascade extenders, please contact
Technical Support.
Which interconnection cable is best?
In electrically ‘quiet’ environments, UTP cable will give the best quality video over
long distances because it has less capacitance per unit length. However, STP/FTP is
usually better in electrically noisy environments, because it resists interference
more strongly (if it is installed correctly!) and limits ground potential differences.
Can the extender system be used between buildings?
No. Ground loops could damage the extender system and attached equipment.
Can multiple Local/Remote units be used by swapping the interconnection cable?
Local units provide full keyboard and mouse emulation, so it is possible to swap or
switch the Local-Remote interconnection to create a KVM matrix-switch system.
Sometimes you may need to reset the keyboard and mouse (by entering the
appropriate command) after a swap or switch. Please call Technical Support before
deploying such a system.
Can the extender be connected into our network?
Absolutely not. Regardless of the cable similarities, the data signals and voltages
used by the extender are different from those used by Ethernet and other types of
networks. Connecting the extender to a LAN hub, switch, repeater, or other
network device, or exposing it to the signal levels present on network data lines
may damage the extender and other devices.

APPENDIX E: AUDIO/SERIAL PORTS
Appendix E: Audio/Serial Ports
Operation & Multi-Port Configuration
This appendix describes audio & serial interface operation for those models that have this
feature:
•
ACU3222A
•
ACU3228A
•
ACUMRA02A
These extender products contain daughter boards that allow bi-directional stereo audio and a
full-duplex serial data link to be sent across the CATx interconnection cable in addition to
PS/2 keyboard, mouse and video.
Serial Interface - Set Up and Operation
No setting up or user adjustments are required. Please note that on dual access Local units,
the serial link is always active.
The Remote unit’s serial port is wired as DTE - the same as that on a PC. To connect a serial
printer or other DTE (rather than DCE device) to the Remote unit, you will need a NullModem crossover cable between the Remote unit and the printer. Select Xon/Xoff software
flow control on the printer and PC.
A serial touch screen may be plugged directly into the Remote unit.
Serial Interface – Handling Multiple Serial Devices
The extender’s serial interface transmits/receives six signals (3 signals in each direction).
Normally, four of these signals are used for hardware handshaking (in addition to TX & RX).
However, because each handshaking line can support signals up to 19,200 Baud it is possible
to configure the serial interface to handle up to three simple 2-wire (Tx/Rx only) serial links.
To do this, you will need to construct a custom breakout cable. Please contact Technical
Support for further information.
47
SERVSWITCH
PS/2 MICRO EXTENDER FAMILY
Audio Interface - Set Up and Operation
The audio interface is line-level and is designed to take the output from a sound card (or other
line-level) source and be connected to a set of powered speakers at the other end of the link.
Stereo audio may be transmitted either way across the link (simultaneously).
No setup is required unless a microphone is connected to the Remote unit.
Connect the extender as follows:
•
Take the line-level output from your sound card (green connector) and connect to ‘Line
In’ on the Local unit.
•
Connect ‘Line Out’ on the Remote unit to a set of powered speakers.
Audio Interface – Using a Microphone
A microphone may be plugged into the ‘Line In’ connector on the Remote unit.
There are two ways of setting up a microphone:
•
The Local unit’s ‘Line Out’ connection should normally be wired to the microphone
input (Pink) on your sound card. The sound card should then be set up to provide
additional amplification (+17dB). This is the preferred connection method.
•
Alternatively, the Remote unit itself can provide microphone amplification. To set this,
open up the Remote unit and locate the jumper labeled ‘MIC’ on the daughter board.
Connect this jumper across the pins. The Local unit’s ‘Line Out’ connection should then
be wired to ‘Line In’ (Blue) on your sound card.
If your microphone is already amplified, follow the second method but DO NOT install the
amplification jumper in the Remote unit.
