Introduction
Thank you for choosing a member of the AdderView
Pro (AV4PRO) family of professional switches from
Adder Technology. There are four versions of the
AV4PRO-DVI, each of which allows a single operator to control up to four computer systems and share peripherals among them in a very flexible manner.
The AV4PRO-DVI can support one video head per channel, whereas the slightly larger AV4PRO-DVI-DUAL,
AV4PRO-DVI-TRIPLE and AV4PRO-DVI-QUAD units support two, three and four video heads per channel, respectively.
Thanks to our high quality, efficient switching technology, each video head can support dual link digital video at up to 450Mpixels per second. In addition to the impressive video performance, these units offer more than just straight switching between four systems. The KVM, speakers and two separate USB devices attached to the AV4PRO-DVI units can either be switched in unison, as normal, or you can 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 AV4PRO-DVI front panels make it straightforward to control which peripherals should connect to each system.
The AV4PRO-DVI units feature
which ensures that the full characteristics of the connected keyboard and mouse are passed to every system.

Multiscreen versions
The AV4PRO-DVI range includes separate models to support one, two, three or four video heads per channel.
Digital and analogue video
The AV4PRO-DVI units use DVI-I
(Integrated) connectors throughout so that DVI digital and/or VGA analogue video may be used (the latter requires the use of suitable adapter cables).
Multiple switching
The 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 onscreen menu or using the front panel buttons.
Intelligent display information
The AV4PRO-DVI units use our EDID
feature to ensure that all computers are supplied with the correct information about each connected video display.

True Emulation
Earlier USB KVM switches relied upon standard keyboard and mouse templates to inform each computer system how to deal with the connected peripherals. The
AV4PRO-DVI range 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 wakeup
The 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, especially 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 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 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.
The emulated section of the switch is shown in blue and handles only the keyboard and mouse. The green enumerated section of the switch handles other

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 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 independently of each other, as required. Thus, your various peripherals can operate with different computers at the same time.

Note: As each channel is chosen using the above RS-232 commands, the peripherals that will be transferred are determined by the current setting of the switching mode.
Control by channel select input lines
Where the external control is via the four channel select input lines of the
OPTIONS port (see pin out opposite), ensure that the configuration menu option
is set to to enable the input lines.
The four input lines are suitable for connection to dry contacts or open collector style outputs. Connecting an input line to GND will cause the AV4PRO-DVI to switch all of its functions to the selected channel:
• Channel 1: Channel select input 1 low
• Channel 2: Channel select input 2 low
• Channel 3: Channel select input 3 low
• Channel 4: Channel select input 4 low
If the input line is held low then all other switching requests by other means will be ignored until the line returns to a high (open) state.
If more than one logic input is low (closed) then the lower channel number takes priority.
Note: The input lines have only limited protection against over voltage.
10
Synchronising multiple units
AV4PRO-DVI units can be connected together so that they operate in a synchronised manner. Thus, two AV4PRO-DVI units can be made to switch two video heads in a similar manner to an AVPRO-
DVI-DUAL. Additionally, two AVPRO-DVI-DUAL units could be made to resemble an AVPRO-DVI-QUAD, while two AVPRO-DVI-QUAD units could be combined in order to switch up to eight video heads simultaneously.
Whenever an AV4PRO-DVI channel is switched, it sends an RS232 command out on its serial interface (marked OPTIONS on the rear panel). An AV4PRO-DVI will switch its channel if it receives the same command on its serial interface. Consequently, by linking the serial interfaces, a master unit may be made to automatically switch one or more slave units as shown in the diagram.
It should be noted that the synchronisation cable deliberately does not have the transmit pin of the Slave End connector linked to the receive pin of the Master End connector. To do so would cause the Slave unit to be able to switch the Master unit. This would setup an endless cyclical switching sequence that would prevent the AV4PRO-DVI devices from operating correctly.

Managing EDID video display information
Whenever a AV4PRO-DVI unit is powered on (or when the option is
selected from the configuration menu), it will interrogate the connected
monitor(s) to determine whether EDID (Extended Display Identification Data) information is available. If EDID information is available, it will be copied and used; otherwise a default set of data, stored within the AV4PRO-DVI, will be substituted. You can also optionally choose to prevent the unit from seeking new EDID information and instead rely only on stored data.
EDID Emulation
The AV4PRO-DVI units use our EDID Emulation feature to ensure that the collected EDID information (up to two pages) is correctly supplied to every connected computer, whether it is currently selected or not:

Performing upgrades
The AV4PRO-DVI unit is fully upgradeable via flash upgrade. Such upgrades require a Windows-based computer system to be linked via the OPTIONS port.
Items required to perform an upgrade
• Optional upgrade cable (see Appendix 2
for pin-out specifications).
• A Windows-based upgrade computer with an RS232 serial port.
• The latest version of the KVM Firmware Uploader and firmware files for the
AV4PRO-DVI unit - available from the Technical Support > Updates section of the Adder Technology website ( www.adder.com
).
To use the KVM Firmware Uploader utility
1 - Obtain and run the KVM Firmware Uploader.
Download the latest AV4PRO-DVI unit KVM Firmware Uploader from the
Adder Technology website and install it on a Windows-based upgrade computer that will be connected to the AV4PRO-DVI 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 - Power off the AV4PRO-DVI unit
Remove the power supply plug from the rear panel of the unit.
3 - Connect the upgrade computer to the AV4PRO-DVI unit
Connect the serial port of the upgrade computer to the OPTIONS port on the rear panel of the unit using the optional upgrade cable.
4 - Invoke upgrade mode
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 ‘ ’.
5 - Run the KVM Firmware Uploader utility
From that folder, select the KVMUploader icon to run the upgrade utility.
The KVM Firmware Uploader dialog will be displayed:

6 - Query the AV4PRO-DVI unit
Click the Query Unit button to confirm that communication is possible with the AV4PRO-DVI unit and to establish its firmware details. If successful, the
‘Unit connected’ field should show the name of the AV4PRO-DVI unit and the current firmware will also be listed.
If the application cannot contact the AV4PRO-DVI 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. continued
There is no need to adjust the computer’s serial port settings as the application will do this automatically.
16
7 - Select the upgrade file to be used
From the main KVM Firmware Uploader dialog, click the Browse... button and select the upgrade file:
AV4Pro_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 Adder Technology Ltd before proceeding.
Check also that the ‘New firmware version’ is greater than the ‘Current firmware version’.
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 AV4PRO-DVI unit or computing equipment.
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’.
8 - Commence the upgrade
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 - Cycle the power
Disconnect the power. When the power is re-applied the AV4PRO-DVI unit will operate using the new firmware.
