Introduction
Thank you for choosing a member of the AdderView 
PRO family of professional switches from Adder 
Technology. This compact unit allows a single operator 
to control up to eight computer systems and share 
peripherals among them in a very flexible manner.
The AV8PRO-DVI model benefits greatly from our 
long history of success in KVM (Keyboard, Video and 
Mouse) switching. As a result, it can reliably switch 
multiple signals (including dual link digital video at up 
to 330Mpixels per second) in a manner that is totally 
transparent during operation. However, this unit 
offers more than just straight switching between eight 
systems. The KVM, speakers and two separate USB 
devices attached to the AV8PRO-DVI can be switched 
in unison between any of the connected systems, as 
normal. However, you also have the option to mix your 
peripherals between any of the systems, to suit your 
current tasks. For instance, you could be creating emails 
on one system, listening to a soundtrack from another 
while a third is sending documents to your printer and 
a fourth performing another task with a different USB 
peripheral. The on-screen menu or the AV8PRO-DVI 
front panel make it straightforward to control which 
peripherals should connect to each system. 
The AV8PRO-DVI also marks the debut of a significant 
advance in USB keyboard and mouse switching. This 
is the first product to feature True Emulation which 
ensures that the full characteristics of the connected 
keyboard and mouse are passed to every system. 
This supersedes the previous method of presenting 
default identities to the systems, which did not allow 
for specialised features present on either the keyboard 
or mouse. With True Emulation, you will find that, 
subject to the correct drivers being used on each 
system, the AV8PRO-DVI will faithfully represent the 
special characteristics of your keyboard and mouse.
Digital and analogue videoEach of the eight computer channels has a DVI-I video connector which allows either DVI digital or VGA analogue signals to be input. At the console connections, the AdderView Pro 8 uses separate DVI-D and VGA connectors to allow the easy attachment of either type of monitor, or to permit dual connections to auto-switching monitors that can operate with either type of input.
Multiple switchingThe attached peripheral devices can be switched collectively to any computer system, or can be linked to separate systems to achieve multiple tasks in parallel. Multiple switching can be controlled from the on-screen menu or using the front panel buttons.        
True EmulationEarlier USB KVM switches relied upon standard keyboard and mouse templates to inform each computer system how to deal with the connected peripherals. The AdderView PRO succeeds in harvesting the true identities of the connected keyboard and mouse and presents those ‘real’ profiles concurrently to every system. Thus, specialist keyboards and mice can be fully supported.

USB Remote wakeupThe USB Remote Wakeup feature is fully supported. Any connected computer can go into sleep mode and be awakened (when its channel is selected) as soon as you press a key or move the mouse. The computer and peripherals must support the USB Remote Wakeup feature.

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 various problems that have 
spawned a number of possible solutions.  
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 switching 
process - a quick and simple control method expected by most users. Reliability 
of switching is also an issue that has plagued enumerated switches, espe\
cially 
when used with certain USB devices and particular operating systems. 
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 w\
hen 
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 computers 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. 
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 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 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 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 highe\
st 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 stabilise 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 independe\
ntly 
of each other, as required. Thus, your various peripherals can operate with 
different computers at the same time.

Connections
Connections do not need to be carried out in the order given within this guide, 
however, where possible connect the power in as a final step.
User console
The ports that make up the user console are where you attach the peripherals 
that will be shared between the computer systems. Ensure that power is 
disconnected from the AdderView PRO unit. 
To connect peripherals to the user console
1 Position your peripheral devices in the vicinity of the AdderView PRO unit 
such that their cables will easily reach.
2 Video monitor: The AdderView PRO supports both DVI digital and VGA 
analogue video signals. Separate DVI and VGA ports are provided for the 
user console connection and you can use either, or both, as required. Where 
a computer provides analogue video, this will be routed through the VGA 
port; when digital video is supplied, this will appear at the DVI-D port\
. 
 Note: The AdderView PRO does not perform any conversions between 
digital and analogue video signals. If a connected system provides only \
analogue video, then no signal will be seen on the digital DVI-D output \
port, 
and vice versa. 
 Attach the lead(s) from the video monitor to the appropriate port connector. 
If your video monitor has dual capabilities then you can link it to both\
 
connectors using appropriate leads.
