Chapter 2: Overview
2. Overview
2.1 Introduction
The ServSwitch™ Freedom is a compact unit created to allow a single operator to access information and control
operations across numerous systems and screens. With the ServSwitch Freedom unit, you can use a single USB keyboard
and USB mouse to fulfill functions that previously required four separate sets. This provides immediate savings in both
desk space and also the time required to access and control up to four systems and screens. The ServSwitch Freedom
features our True Emulation technology (see Appendix B), which ensures that the full characteristics of the connected USB
keyboard and mouse are passed to every system.
In addition to switching the keyboard and mouse, the ServSwitch Freedom can also share a set of speakers and two
separate USB peripherals between the four systems. This can be done either in concert with the keyboard and mouse (and
each other) or totally independently.
The ServSwitch Freedom unit can be used in combination with various Black Box extender products (such as the Wizard SRX
ACU5501A) to extend the distance between the user and the computers under control.
Switching between the systems connected to the ServSwitch Freedom can be achieved in five different ways:
• The innovative Glide and Switch automatic switching utility (see Appendix B),
• The COMPUTER button on the top panel,
• Keyboard hotkey combinations,
• Mouse button combinations,
• Remote control by another device*.
Where additional feedback is required as to which systems and screens are selected at any time, the optional ServSwitch
Freedom LED Monitor kit provides discreet stick-on LED monitor indicators. When a system/screen is selected, a
corresponding LED monitor indicator illuminates (in a choice of colors) to confirm the action.
The video displays are connected directly to their respective systems as usual. A single USB link (plus
an optional speaker connection) is made between each system and the ServSwitch Freedom unit.
The keyboard/mouse,
the speakers and two
individual USB channels
can be collectively or

2.2 Features
Multiple screens, multiple systems
The ServSwitch Freedom unit allows you to control up to four individual computer systems and their display screens using just one
keyboard and mouse set. You can also share two further USB peripherals between the systems.
Multiple channel switching options
You have a choice of five different ways to switch between the various system/display channels including control by mouse but-
tons, keyboard hotkeys, the unit front panel, optional remote control by another device or using our Glide and Switch technology
– more on this below.
Automatic channel switching with Glide and Switch technology
Our patent pending Glide and Switch technology allows the ServSwitch Freedom unit to determine the precise moment that you
wish to change between channels by monitoring the mouse pointer movements. All switching intelligence is fully contained within
the unit, no extra software utilities are required on your mission critical computer systems.
True Emulation
Earlier USB KVM switches relied upon standard keyboard and mouse templates to tell each computer system how to deal with
the connected peripherals. The ServSwitch Freedom gathers the true identities of the connected keyboard and mouse and pres-
ents those “real” profiles concurrently to every system. Thus, specialized keyboards and mice can be fully supported.
Compact size
The ServSwitch Freedom is contained within a sturdy yet compact metal case which can easily be concealed within the cable
flows behind your desk.
Optional channel indicators
The ServSwitch Freedom LED Monitor kit provides individual indicator modules that make it easy to see which display screen is
currently selected.

3.3.5 Optional LED indicator connections
The optional ServSwitch Freedom LED Monitor module (part number: KV0004A-LED) enables you to add LED (Light Emitting
Diode) indicators to each of your video display screens to show which are active.
Note: The ServSwitch Freedom switch requires firmware version 2.0 or later to be installed. Please see 4.7 Performing
upgrades for details about how to check.
The optional ServSwitch Freedom LED Monitor module connects to the OPTIONS port of the main ServSwitch Freedom switch.
Each individual LED monitor indicator then connects to one of the ten ports on the ServSwitch Freedom LED Monitor module.
Notes: The ServSwitch Freedom LED Monitor module MUST be connected before the switch is powered on, otherwise the mod-
ule will not be recognized. Also, if the module is temporarily disconnected from the switch during operation, communication
between the two will cease and the switch will need to be re-powered with the ServSwitch Freedom LED Monitor module
attached.
Before operation of the LED indicators can occur, it is necessary to temporarily connect the ServSwitch Freedom switch to a
Windows computer. This will allow you to use the Glide and Switch application to program the required operation of the switch.
Please see 4.5 Configuring LED indicators for details about using the Glide and Switch configuration application.
3.3.5.1 To connect the ServSwitch Freedom LED Monitor module and indicators
1. Remove power from the switch. Use the flat cable supplied with the ServSwitch Freedom LED Monitor kit to link the module to

4.4 Multi-Monitor Glide and Switch configuration
4.4.1 Installing drivers and multi-monitor config app
(Windows only)
In order to use Multi-Monitor mode you will need to install a Multi-Monitor Glide and Switch driver (available for download from
the Black Box website. Go to the KV0004A product page and click on the 'Resources' tab) onto each PC that has multiple
monitors attached.
1. On each multiple monitor PC, run the downloaded file. After accepting the licence agreement you will be prompted to choose
a destination folder. Either accept the suggested location or change it, as necessary.
Note: The Install for all users option should be ticked if there are more than one user account on the PC and all need to use
Glide and Switch.
2. The options available during installation are as follows:
• Full Install, (this is recommended), or
• Options to install individually:
• Configuration App.
This is the Glide and Switch application and needs to be installed only on the PC that will be used to set up the
ServSwitch Freedom switch via the supplied flash upgrade cable and OPTIONS port.
• Visual C++ Runtime
The C++ runtime library is a windows component that is required by the multi-monitor driver in order to run its helper
applications. It is pre-installed with Windows but is offered here as an option as you may want to keep an older version
already installed on your system, or you may already have a newer version in your copy of Windows.
• Drivers.
Multi-Monitor Glide and Switch drivers that are required on each PC that will be using Multi-Monitor.
Choose the required components and click the Next > button.
3. Once the chosen components have been installed, click the Finish button.
Note: On the PC that will be used to set up the ServSwitch Freedom switch, you can optionally tick ‘Click to run the Glide and
Switch Configuration Application’ in the lower left corner to immediately begin using Glide and Switch - see 4.5 Configuring
multiple monitors opposite for details.
Note: On each PC that you installed the driver, a process called mumoapp.exe will remain running.
724-746-5500 | blackbox.com
Page 26
Chapter 4: Configuration
4.4.2 Configuring multiple monitors
Multi-Monitor configuration is similar to normal Glide and Switch setup except that you can add more than one display per PC, up
to a total of eight per machine.
Note: It is necessary to install a driver on each PC that has multiple displays - see 4.4.1 Installing drivers and multi-monitor config
app opposite.
1. Use the supplied flash upgrade cable to link the computer serial port to the ServSwitch Freedom OPTIONS port. If the optional
ServSwitch Freedom LED Monitor module is connected to the OPTIONS port, then instead connect the upgrade cable between
the computer serial port and the TO KEYPAD OR PC port of the ServSwitch Freedom LED Monitor module (see 3.3.5 Optional
LED indicator connections for details).
2. If it is not already running, start the Glide and Switch configuration application.

display screens per computer to the map area.
For example, to add two monitors for PC 1, click the red computer icon twice. The two red monitor representations will be
placed side by side within the Glide and Switch map area. See Figure 4-4.
Figure 4-4. Adding new screens
4. Arrange the colored rectangular screen representations to mimic the physical layout of the actual displays. For example, you
may wish to have the two screens of PC1 side by side, with the two screen screens of PC2 below them (as shown left), or
some other arrangement to reflect the actual positions of the physical monitor screens.
The important thing is to define where each screen edge abuts to the next so that the ServSwitch Freedom switch can
determine the correct moments to switch channels.
Use the small black squares around the perimeter of each highlighted screen representation to change their size or stretch
them.
Note: The numbers of the screen representations relate directly to the four channels on the ServSwitch Freedom switch, while
the letters relate to the screen hierarchy attached to any single computer (i.e. A is primary, B is secondary, etc.).

Mouse acceleration allows you to move the mouse pointer quickly across the
large areas of the screen in response to small but sharp shifts in the mouse
position. The Configure > Mouse... option provides settings between 0 and 50,
however, a value of 12 to 15 will give a typical Windows-like default operation.
4.6.3 Mouse parking... setting
Mouse parking allows you to optionally determine where the mouse pointer
for each system should be placed when the focus moves to a different system/
video screen. The Configure > Mouse parking... option displays vertical and
horizontal scroll bars. Use the scroll bars to pinpoint the position that should be
used to park the dormant mouse on each screen.
4.6.4 Switch... settings

Chapter 4: Configuration
4.7 Performing upgrades (Windows only)
The ServSwitch Freedom unit is fully upgradable via flash upgrade. Such upgrades require a Windows-based computer system to
be linked via the OPTIONS port.
Items required to perform an upgrade
• Upgrade cable (supplied Flash Upgrade Adapter plus a CAT5 patch lead [see Appendix C for overall pin-out specifications]).
• A Windows-based upgrade computer with an RS-232 serial port.
• The latest version of the KVM Firmware Uploader and firmware files for the ServSwitch Freedom unit (available for download
from the Black Box website. Go to the KV0004A product page and click on the 'Resources' tab).
4.7.1 Using the KVM Firmware Uploader utility
1. Download the latest ServSwitch Freedom unit KVM Firmware Uploader from Black Box Technical Support or from the Black
Box website and install it on a Windows based upgrade computer that will be connected to the ServSwitch Freedom unit. The
files are supplied as a compressed ZIP file. Decompress the ZIP file with an appropriate tool such as WinZip (www.winzip.com)
and copy all contained files to the same folder on the upgrade computer.
2. Remove the power supply plug from the rear panel of the unit.
3. Use the supplied Flash Upgrade Adapter and any CAT5 patch cable to link the serial port of the upgrade computer to the
ServSwitch Freedom OPTIONS port. There is no need to adjust the computer’s serial port settings as the application will do this
automatically.
4. While powering on or when already powered: Press and hold the COMPUTER and MODE buttons (for up to ten seconds) until
the numeric indicator shows ’U’.
5. From the folder created/used in step 1, select the KVMUploader file/icon to run the upgrade utility. The KVM Firmware
Uploader dialog will be displayed:
Figure 4-9. KVM Firmware Uploader utility screen.
6. Click the Query Unit button to confirm that communication is possible with the ServSwitch Freedom unit and to establish its
firmware details. If successful, the ‘Unit connected’ field should show the name of the ServSwitch Freedom unit and the cur-
rent firmware will also be listed.
If the application cannot contact the ServSwitch Freedom unit, re-check the connection cable and click the Advanced... button
to check that the correct serial port is being used. Change the serial port within the Advanced... section, if necessary.

7. From the main KVM Firmware Uploader dialog, click the Browse... button and select the upgrade file:
FREEDM_xxx.txt
where xxx is the firmware version.
The upgrade file details will be displayed within the dialog.
IMPORTANT: Check that the ‘Intended Target Units’ field matches the ‘Unit Connected’ field. If these fields do not match then
you may have an incorrect upgrade file; check with Black Box Technical Support before proceeding. Check also that the ‘New
firmware version’ is greater than the ‘Current firmware version’. See Figure 4-10.
Check that the
‘Intended Target
Units’ field
matches the ‘Unit
Connected’ field.
Check also that
the ‘New firmware
version’ is greater
than the ‘Current
firmware version’.
Figure 4-10. KVM Firmware Uploader utility screen with upgrade file selected.
8. To begin the upgrade process, click the Upload Now button. The progress will be shown within the dialog. Should you decide
not to continue with the upload at any stage, click the Abort button; response to this is usually immediate, however, during an
erase command, the upload will not be aborted until the erase is complete (this may take a few seconds).
9. Disconnect the power. When the power is re-applied the ServSwitch Freedom unit will operate using the new firmware.
4.7.2 Issues to consider when performing flash upgrades
The upgrade program rewrites the internal firmware code. If the upgrade process is interrupted then the unit will have invalid
code and will not be able to operate. It is therefore good practice to ensure that the upgrade process is always fully completed. A
partial or failed upgrade may be rectified by performing another upgrade.
WARNING: Running faulty or partially upgraded code may have unpredictable results and may damage your ServSwitch Freedom
unit or computing equipment.

5. Operation
5.1 Selecting a computer
There are five ways to switch the common peripherals to specific computer channels:
• Using the innovative Glide and Switch automatic switching utility
• Using the front panel controls
• Using hotkeys
• Using mouse button presses
• Using external switching control (RS-232 or input lines)
5.1.1 Selecting a computer using the Glide and Switch utility
Once configured, Glide and Switch allows you to change channels merely by moving the mouse to edge of one screen towards
the next screen. As the mouse pointer reaches the edge it will cause the channel to automatically change and will jump to the
next screen.
Notes:
Glide and Switch cannot be enabled until a layout has been configured and downloaded to the ServSwitch Freedom unit - see
4.3 Glide and Switch configuration.
The mouse will not flow across the screens while any mouse buttons are pressed down - this prevents undesired behavior
when dragging windows around or group-selecting items.
You can determine which peripherals will be switched by Glide and Switch independently of those that would be switched
with any other method. See Switch Mode within the 4.3.3 Optional Glide and Switch operations and settings section.
You can continue to use any of the other channel switching methods while Glide and Switch is enabled.

Appendix A. What is True Emulation?
True Emulation represents a significant breakthrough in sharing USB devices between two or more computer systems. Until this
point, the problem has been how to create a USB switch that provides all of the following:
• Quick, transparent and reliable switching,
• Accurate representation of the connected USB keyboard and mouse,
• Switching control via the connected USB keyboard and/or mouse.
The difficulty in achieving all of the above requirements has been due to the complexity of the USB standard. This has led to vari-
ous problems that have spawned a number of possible solutions.
A.1 Enumerated USB switching
The earliest attempts to switch USB devices applied a relatively ‘hands off’ approach. Enumerated USB switches are the electronic
equivalent of those old mechanical KVM switches with a large knob on the front.
Enumerated switches are so called because a connected USB device will be required to perform a full initiation (a process called
Enumeration) every time it is switched; just as if you had pulled out the plug and then reconnected it.
Enumerated switches simply pass all signals straight through between the USB device and the computer, they do not attempt to
interpret any data. For most devices, this offers an advantage because the switch just leaves them to get on with their jobs with-
out any interference or any hit on performance. However, it means that a USB keyboard or mouse cannot be used to control the
switching process - a quick and simple control method expected by most users. Reliability of switching is also an issue that has
plagued enumerated switches, especially when used with certain USB devices and particular operating systems.
A.2 Emulated USB switching
The issues with interpreting the complex USB data streams and recreating (or Emulating) the identity of attached USB devices
were eventually solved, leading to the creation of the Emulated USB switch.
A neat side effect of the technique used is that each computer can be fooled into thinking that the USB device is permanently
connected to it, even when the device is switched to another computer. This means that the enumeration process for the USB
device takes place only once, during the first power on. After that, a computer merely sees a dormant version of the USB device
whenever the device is actually connected to a different computer.
However, it remains a complex task to dynamically assume the identity of a USB device, distribute it among the connected com-
puters and maintain all of the necessary signals, states and processes. Therefore, manufacturers have previously relied upon a
fixed keyboard and mouse profile that is declared to each computer, regardless of the actual connected devices. This precluded
the use of any special keyboard or mouse features over and above the standard layouts.
A.3 True Emulation
Mindful of the limitations associated with the previous USB switching techniques, we set about creating a more effective and ele-
gant solution. After a great deal of research and development, True Emulation is the result.
True Emulation allows the complete identity of the keyboard and mouse to be copied and then presented to all of the connected
computers. This means that any keyboard offering specialist function keys or any mouse with extra features will be fully supported
at each computer. As with the previous emulation method, the unselected computers will continue to see the identities of the
keyboard and mouse, which means that no enumeration is necessary when their link becomes active once again. This not only
helps to speed up the rate of reconnection, but also raises the reliability of switching because USB links are at their most vulnera-
ble during the enumeration process.
True Emulation relies upon a high speed circuit, called an Emulation Engine, to fully emulate the USB device identities and also
interpret keyboard and mouse data streams. The result is full support for KVM switching control via hotkey presses or the third
button/scroll wheel of a mouse.

True Emulation is not necessarily required by other USB devices, which is why you will also find two enumerated circuits included
(shown in green within the block diagram) alongside the True Emulation feature (shown in blue). This allows those other USB
devices to operate at their highest speeds, without any intervention. The enumerated circuits benefit greatly from the USB Hubs
that are jointly used with the True Emulation system. Because they interface directly and permanently with each computer, they
help to stabilize the dormant links, making errors during enumeration much less likely.
The dual switching arrangement provides further flexibility because the True Emulation and enumerated sections can be
switched in unison or independently of each other, as required. Thus, your various peripherals can operate with different
computers at the same time.

ServSwitch Freedom
Appendix B. What is Glide and Switch?
Glide and Switch represents true innovation in KVM switching. For the first time, Glide and Switch allows users to automatically
switch between target computers simply by moving the mouse pointer from screen to screen. What makes this such a revolution
is that you no longer need software to be installed on your mission critical computers in order to do this. Glide and Switch resides
on the switch itself, sensing screen boundaries and instantaneously switching keyboard and mouse to the defined target comput-
er. Glide and Switch can be configured for almost any combination of screens using the included configuration application which
allows you to declare the individual screen sizes and visually position each one relative to the others.

Figure B-1. Moving the mouse beyond a screen border causes Glide and Switch to switch the channel
Glide and Switch consists of special code within the ServSwitch Freedom unit plus an intuitive graphical configuration application.
First you inform the Glide and Switch configuration application how many screens you have, their pixel resolutions and how they
are physically arranged (e.g side-by-side, vertical stack, square formation, etc.). You then download this information to the
ServSwitch Freedom unit and this is used during operation to determine the precise moment to switch from one screen/system to
the next.
The beauty of Glide and Switch is its simplicity of configuration and operation. Once the initial configuration has taken place, all
monitoring and switching is handled within the ServSwitch Freedom without need for extra connections or software utilities.
Issues when using Glide and Switch
• The ServSwitch Freedom unit must have a minimum of firmware version 2.00 installed to operate with Glide and Switch.
• Glide and Switch does not run any special utilities on each computer and thus has no way to instruct the computers to hide
their mouse pointers when they are deselected by the ServSwitch Freedom unit. Therefore, the ServSwitch Freedom ‘parks’
each mouse pointer in the bottom right corner of the screen immediately before changing the channel. In most cases this will
cause no issues, however, it may be noticeable in circumstances such as the following:
• If the task bar is set to auto hide and it is positioned either along the bottom of the screen (as default) or along the right hand
side, then the task bar will automatically reappear when the mouse pointer is parked.
• When playing full screen video, the on-screen controls (play, pause, seek etc.) will very likely be revealed when the mouse
pointer is parked.
• The mouse will not flow across the screens while any mouse buttons are pressed down - this prevents undesired behavior
when dragging windows around or group-selecting items.
