CHAPTER 1: SPECIFICATIONS
2.1 INTRODUCTION
The Freedom II* series of switches are focused upon allowing you to seamlessly access multiple computers and their display
screens, using common peripherals.
Freedom II switches allow you to use a single USB keyboard and USB mouse to fulfill functions that previously required four
or eight separate sets. This provides immediate savings in both desk space and also the time required to access and control
systems and screens. The KV0004A-R2 variant supports up to four connected systems while the larger KV0008A-R2 allows up to
eight systems to be accessed.
Freedom II switches feature our True Emulation technology (see Appendix C), 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, Freedom II switches can also share a set of speakers and two separate USB
peripherals between the various systems. This can be done either in concert with the keyboard and mouse (and each other) or
totally independently.
Freedom II switches 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.
* References to Freedom II apply equally to both the KV0004A-R2 and KV0008A-R2 products.

Figure 2-1. Overview of the Freedom II.
Switching between the systems connected to the Freedom II can be achieved in five different ways:
The innovative Glide and Switch automatic switching utility (see Appendix C),
The COMPUTER button on the top panel,
Keyboard hotkey combinations,
Mouse button combinations,
• Remote control via an external system.
Where additional feedback is required as to which systems and screens are selected at any time, the optional 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.
Glide and Switch
An innovative in-built utility that allows
the unit to automatically switch between
channels by monitoring the mouse pointer
position.
The keyboard/mouse, the speakers and two
individual USB channels can be collectively or
separately switched through to each PC system
using a variety of manual and/or automatic
switching methods.

2.2 FEATURES
Multiple screens, multiple systems
The Freedom II units allow you to control up to four (or up to eight) 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 buttons,
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 Freedom II units 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 Freedom II switches gather the true identities of the connected keyboard and mouse and present those
“real” profiles concurrently to every system. Thus, specialized keyboards and mice can be fully supported.
Compact size
Freedom II switches are contained within sturdy yet compact metal cases which can easily be concealed within the cable flows
behind your desk.
Optional channel indicators
The Freedom LED Monitor kit provides individual indicator modules that make it easy to see which display screen is currently select-
ed.

3.3.3 POWER IN CONNECTIONS
The Freedom II switch is supplied with a single power adapter but offers the facility to use a second input in order to provide opera-
tional redundancy. The Freedom II unit can operate perfectly well from a single power adapter operating alone. When two adapters
are connected, the unit will spread its load between them; should one power input fail, 100% of the load will be transferred to the
other power adapter without a break in operation. Remote checking of the power inputs is possible at any time via the browser inter-
face.
There is no on/off switch on the Freedom II unit, so operation begins as soon as power is applied at either port.
3.3.3.1 TO CONNECT A POWER ADAPTER
1. Attach the output connector of the supplied power adapter to either of the two power input sockets on the left side of the rear
panel. See Figure 3-5.
Figure 3-5. Attaching the power adapter lead(s) to the power input socket(s).
Note: The outer sleeve of each power connector will retract slightly as it locks into place.

3. Connect the power cord to a nearby main supply socket.
4. Where power redundancy is required, repeat steps 1 to 3 for a second power adapter.
IMPORTANT: Please read and adhere to the electrical safety information given within the Safety information section of this guide. In
particular, do not use an unearthed power socket or extension cable.
Note: Both the switch and its power supplies generate heat when in operation and will become warm to the touch. Do not enclose
them or place them in locations where air cannot circulate to cool the equipment. Do not operate the equipment in ambient tempera-
tures exceeding 40 degrees Centigrade. Do not place the products in contact with equipment whose surface temperature exceeds 40
degrees Centigrade.
3.3.3.2 TO DISCONNECT A POWER ADAPTER
1 Isolate the power adapter from the mains supply.
Note: If you are replacing one of dual power adapters during operation, it is not necessary to also remove power from the other
adapter.
2 Grasp the outer body of the power adapter plug where it connects with the Freedom II unit.
3 Gently pull the body of the outer plug away from the switch. As the body of the plug slides back, it will release from the socket and
you can fully withdraw the whole plug.
2. Connect the IEC connector of the supplied country-specific power cord to the socket of the power adapter. See Figure 3-6.

3.3.4 OPTIONAL LED INDICATOR CONNECTIONS
The optional Freedom LED Monitor module (part number: KV0004A-LED) with four indicators enables you to add LED (Light Emitting
Diode) indicators to each of your video display screens to show which are active.
The optional Freedom LED Monitor module connects to the port of the main Freedom II switch. Each individual LED moniOPTIONS -
tor indicator then connects to one of the ten ports on the Freedom LED Monitor module.
3.3.4.1 TO CONNECT THE FREEDOM LED MONITOR MODULE AND INDICATORS
1. Remove power from the switch. Use the flat cable supplied with the Freedom LED Monitor kit to link the module to the OPTIONS

3.3.6 SWITCHING CONTROL VIA THE OPTIONS PORT
The OPTIONS port allows an external serial input, typically from a computer, to control the selection of the various channels. You can
use either an optional serial cable or alternatively construct a custom cable to link the Freedom II switch and the computer. For pin-
out details of the custom cable, see Appendix A.
Upon receipt of the correct code, the Freedom II will switch immediately to the appropriate channel.
3.3.6.1 CONNECTING A COMPUTER FOR REMOTE CONTROL
The cable link from the computer needs to connect the transmit (TXD) line of the computer to the receive (RXD) input of the Freedom
II and also link the ground terminals (GND) of the two devices. See Appendix A for details.
1 Use an optional serial cable to link the port on the rear panel of the Freedom II switch and a vacant serial port on the OPTIONS
computer.
Note: If the optional is used with the Freedom II, connect the computer instead to the TO KEYPAD Freedom LED Monitor module
OR PC port on the . Freedom LED Monitor module
IMPORTANT: Do not connect
the OPTIONS port to any
network.

4.3 MULTI-MONITOR GLIDE AND SWITCH CONFIGURATION
4.3.1 INSTALLING DRIVERS AND MULTI-MONITOR CONFIG APP
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 Freedom II 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 option should be ticked if there are more than one user account on the PC and all need to use Glide Install for all users
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 Freedom II
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 appli-
cations. 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 Freedom II 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 4.3.2 Configuring multiple
monitors for details.
Note: On each PC that you installed the driver, a process called mumoapp.exe will remain running.

4.3.2 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 4.3.1 Installing drivers and multi-monitor config app.
1 If it is not already running, start the Glide and Switch configuration application on the computer that is connected to the
network port of the Freedom II switch. See Installing the standard configuration application for details.
2 On the icon bar, click the red, green, blue and yellow screen icons (or use the Screens menu) to add the required number of 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 4-12.
Figure 4-12. Multi-Monitor map area
3 Arrange the coloured 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 above), 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 Freedom II 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 Freedom II switch, while the letters
relate to the screen hierarchy attached to any single computer (i.e. A is primary, B is secondary, etc.).
4 [Optional step] If you need more squares on the grid in order to arrange many displays in a row, right click on an empty square
(or on the darker gray edging) to enlarge the grid. Further right clicks will add even more empty squares.
5 Continue from step 3 of the standard Glide and Switch configuration instructions.

5.1.3 SELECTING A COMPUTER USING HOTKEYS
Using hotkey combinations, you can quickly switch the keyboard, mouse, speakers and USB peripherals to any computer channel.
5.1.3.1 USING STANDARD HOTKEY PRESS COMBINATIONS
The standard hotkey press combinations allow you to change channels with the minimum of keypresses:
1. Simultaneously press and hold CTRL and ALT (or other hotkeys, if altered).
2. While still holding CTRL and ALT, press the number key of the required channel address (or the TAB key), then release all of the
keys.
Note: The numbers on your keyboard’s numeric keypad are not valid, use only the numeral keys above the QWERTY section.
The ports (K/M, audio and/or USB) that are switched using this method depend upon the switching mode that is currently set
using the front panel buttons.
The range of standard hotkey combinations are as follows:
Note: If your hotkeys have been changed, substitute them for CTRL and ALT in the examples given here.
CTRL ALT 1 Selects channel 1
CTRL ALT 2 Selects channel 2
CTRL ALT 3 Selects channel 3
CTRL ALT 4 Selects channel 4
CTRL ALT 5 Selects channel 5
CTRL ALT 6 Selects channel 6
CTRL ALT 7 Selects channel 7

PROBLEM:
My computer and the Freedom II switch are connected to the same network but I can’t make contact using a web browser.
There may be another device using the same address as the Freedom II default (192.168.1.22) or your computer may be on a different
subnet.
REMEDIES:
• Check whether any other device on your immediate network is using the same address and temporarily disconnect it, if
possible.
• Make a temporary direct connection between your computer and the switch in order to change the IP address used by the
switch.
• Check that your computer and the switch are on the same subnet. If necessary, change your computer’s subnet mask setting
to encompass that of the switch, e.g. instead of 255.255.255.0, try 255.255.0.0.

APPENDIX B - 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andmouse,
• SwitchingcontrolviatheconnectedUSBkeyboardand/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 various
problems that have spawned a number of possible solutions.
B.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 without
any interference or any hit on performance. However, it means that a USB keyboard or mouse cannot be used to control the switch-
ing 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.
B.2 EMULATED USB SWITCHING
The issues with interpreting the complex USB data streams and recreating (or ) the identity of attached USB devices were Emulating
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 con-
nected 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 comput-
ers 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.
B.3 TRUE EMULATION
Mindful of the limitations associated with the previous USB switching techniques, we set about creating a more effective and elegant
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 key-
board 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 vulnerable 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 inter-
pret 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 sta-
bilize 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.

handles only the keyboard and mouse. The green enumerated section of the switch handles other USB devices
and also uses the USB hubs to link with the computers.
