Conguration
INITIAL DISPLAY SETUP
The multi-viewer switch defaults to an output resolution of 1920 x 1080. If you are using
a display which only supports smaller resolutions, you will need to congure the output
resolution to match.
This is performed using the hotkey combination: L Ctrl | L Ctrl | F11 | d | #
where # represents the desired resolution:
1 = 2048 x 2048
2 = 2560 x 1440
3 = 2560 x 1600
4 = 1920 x 1080
5 = 1920 x 1200
6 = 3840 x 1080
7 = 3440 x 1440
8 = 3840 x 2160
The above hotkey function is particularly useful if the output display is unable to display
the default resolution and you cannot view the OSD menu.
GENERAL CONFIGURATION
The conguration of your multi-viewer switch is achieved through the OSD:
• Video Settings, including output resolution, scaling, borders, preset selection, etc.
• Channel Settings, including front panel display channel names and security levels, front
panel button colors etc.
• USB Settings, including mouse conguration and hotkey choice.
• Audio Settings, including audio mixing and volume levels.
• Advanced Operation, including factory reset.
To access the OSD menu, type: L Ctrl | R Ctrl | o
The menu will appear in the bottom left part of the primary screen and you use your
mouse to click the required options, with all changes being implemented upon exiting
the OSD. See page 11.
Using with dual head computers
Dual head computers (Windows or Linux) may be connected to channels 1+2 or 3+4. A
video connection is required to each input channel, together with a single USB and audio
connection to the primary channel (ie 1 or 3). Note: Dual-head Macs are not supported.
Windows operation
In addition, a Windows 10 driver is required, which may be downloaded from www.adder.
com.
On each multiple monitor computer, run the downloaded le. After accepting the licence
agreement you will be prompted to choose a destination folder. Either accept the
suggested location or change it, as necessary. No conguration is required.

COPY & PASTE
The optional Copy & Paste function enables seamless, high-speed copying of les and
text from one Windows 10 computer to another. For details about using this feature,
please see page 25.
There are two ways to use the Copy & Paste function:
Mode 1: Using the internal COM Device - used for transferring only text, up to 1,000
characters and requires no external storage device.
Mode 2: Using an external USB Device - can transfer les as well as text.
To use either of these options, you rst need to download and install a small driver le
onto all computers that are required to use the Copy & Paste function. You then need to
enable the required mode: COM Device (see right) or USB Device (see page 19).

MANAGING WINDOWS
In everyday use, the multi-viewer switch has two main modes of operation:
• User mode - this is the normal mode of operation, where the switch is essentially
transparent. This means that your commands pass straight through to interact with the
host PC(s), as if you were directly connected to them.
• System mode - in this mode, your link with the PC(s) is temporarily suspended and
instead you interact directly with the switch. This allows you to perform certain tasks,
such as resizing windows and arranging preset layouts.
It is quick and easy to change between the two modes, as follows.
Entering and exiting system mode
To enter system mode
• On the keyboard, press and release the following: Left Ctrl then Left Ctrl then o
Note: In the pages that follow, such sequences are shown in the form: L Ctrl | L Ctrl | o
or
• On the mouse, either click the scroll wheel, or for a ve-button mouse, select either
of the side buttons. Note: The mouse must be set to use Absolute Mode (see page 14) .
Within system mode you will see a large blue cursor; in this mode keyboard strokes and
mouse movements are not transmitted to the computers, but instead are interpreted
within the multi-viewer switch.
To return to user mode
• Press L Ctrl | L Ctrl | u to return to user mode.
or
• On the mouse, either click the scroll wheel, or for a ve-button mouse, select either
of the side buttons.
Taking control of a window
1 In a multi-window layout, enter System Mode, as described above.
2 Move the large blue cursor to the window that you wish to take control.
3 Now, either:
• Take control of the chosen window at the current size: Click the scroll wheel.
or
• Maximise and take control of the chosen window: Double click the left mouse
button.
In either case, you will revert to user mode with control of the selected computer.

Custom Preset Layouts
In system mode, the mouse cursor is also responsible for re-sizing and moving windows
around within the display canvas. It is advisable to begin with one of the predened
layouts and adjust it to suit your requirements. These layouts can be selected before or
after entering system mode:
• For tile layout, use the hotkey combination: L Ctrl | L Ctrl | q
• For focus layout, use the hotkey combination: L Ctrl | L Ctrl | s
• For a custom layout, use the hotkey combination: L Ctrl | L Ctrl | F#
(where F# is the required function key: F1 to F8)
Manipulate the windows to the desired sizes and locations, then apply the new layout to
a function key: L Ctrl | L Ctrl | F11 | Ins | F#
(where F# is the required function key: F1 to F8).
Once you have exited system mode, you will be able to switch between the predened
tile and focus layouts as well as recall your own custom presets.
Resizing and moving windows
There are a number of options available when resizing windows, including the options to
retain the aspect ratio or select only a partial element of the computer’s display.
To use autoscaling
The autoscaling feature allows selected windows to ll the screen, either respecting or
overriding the aspect ratio, depending on the selected option. Autoscaling can be enabled
either through the OSD menu or by using the following hotkey combinations:
• To enable autoscaling with aspect ratio maintained: L Ctrl | L Ctrl | F11 | w | w
• To enable autoscaling without aspect ratio being maintained: L Ctrl | L Ctrl | F11| w | y
• To disable autoscaling: L Ctrl | L Ctrl | F11 | w | n
With your preferred scaling option selected, windows can now be manipulated using the
blue mouse cursor.
To move a window
Locate the blue mouse cursor anywhere within the window. Press and hold the left mouse
button and drag the window to your desired location. Release the left mouse button.
To resize a window
Place the blue mouse cursor at the lower-right corner of the required window. Press
and hold the right mouse button and drag to resize the window up or down accordingly.
Release the right mouse key when the window is at the desired size.
Depending on the current autoscaling setting, the video will (or won’t) adjust in size and/
or aspect ratio. To force the source to rescale within the dened window you can use
either of the following:
• To ll with a xed aspect ratio: L Ctrl | L Ctrl | F11 | w
• To ll with a non-xed aspect ratio: L Ctrl | L Ctrl | F11 | y

USING COPY & PASTE
The optional Copy & Paste function allows you to copy text and les from one host PC
to another.
There are two ways to use the Copy & Paste function:
Mode 1: Using the internal COM Device - used for transferring only text, up to 1,000
characters and requires no external storage device.
Mode 2: Using an external USB Device - can transfer les as well as text.
Initial conguration
To use the Copy & Paste function, you will rst need to download and install a small
driver le onto all computers that are required to use the function. You will also need to
choose which mode you wish to use. Please see page 18 for details.
Using the COM Device mode
Allows you to Copy & Paste up to 1,000 plain text characters using the switch’s memory
for storage. It is designed to support the quick transfer of short text information
between sources, such as telephone numbers, emails, web links, etc.
To use the COM Device mode
1 On the source computer, highlight the text (up to 1,000 characters) and perform a
standard copy function using the mouse or keyboard. The copied text is stored within
the switch’s local memory.
2 Switch to the target computer and perform a standard paste function to the desired
location. The text is copied as plain text, with no formatting parameters.
Note: A small pop-up window on the taskbar provides status updates once text is copied or
available for paste on a specic computer. The last copied data will remain stored in memory,
until any other copy function is performed. This allows you to paste the same text on several
computers.
INSTALLATIONCONFIGURATIONOPERATION
Using the USB Device Mode
The USB Device mode uses an external USB storage device to store copied data and
allows you to copy & paste both text and les from one computer to another (up to
999Mb). It is designed to support large text and le copying between sources.
To use the USB Device mode
1 On the source computer, highlight the desired text or choose a le and perform a
standard copy function using the mouse or keyboard. The copied data is stored on the
external USB storage device.
2 Switch to the target computer and perform a standard paste function via the mouse
or keyboard to the desired location.
The last copied data will be retained within the USB storage device (until such time as
it is replaced by another copy action) so that you can paste pasting the same data on
several computers.
Note: When moving to a specic computer, the “USB External Storage Auto-run” pop-up
message will appear. It is possible to disable this in the conguration options.
