Thank you for choosing the ADDERView ® AVS-1124 secure multi-viewer switch for working simultaneously with up to four computers. You can choose to view the output of any computer on either connected video display or view all four outputs on one display.

Focus automatically changes between computers as the mouse pointer is moved into each related window.

Features

• Uni-directional keyboard, video, mouse and audio data paths prevent any potential information leakage through shared peripherals.

• No shared memory between channels: The keyboard and mouse processor is powered down and reset at each switchover to thwart shared data leakages.

• Automatic switching between ports simply by moving the mouse between windows, whilst depressing the Ctrl key (a security feature).

• Clear channel identification to reduce the chances of operator error by displaying a user defined name and security classification for each channel on the status display.

The color of the channel indicators may also be configured to reflect the security classification.

• Hardware anti-tampering: Holographic anti-tampering labels protect the product’s enclosure, providing a clear visual indication if it has been opened or compromised.

• Restricted USB function: The USB ports will only accept HID (Human Interface

Devices), such as keyboards and mice.

• There is no access to the product’s firmware or memory through any port. Firmware is permanently stored in non-reprogrammable Read Only Memory (ROM) to prevent modification.

• High quality 4K video output resolution.

• Dual video outputs where the 2nd either duplicates the 1st or extends the desktop.

• Connect to either single or dual head computers.

• Analog audio with Hold feature.

Switching between computers can also be controlled from the smart front panel or by using keyboard shortcuts. Multiple techniques are employed to ensure that no crosstalk can occur between the connected computer channels.

Configuration

INITIAL DISPLAY SETUP

The secure multi-viewer switch defaults to an output resolution of 3840 x 2160. If you are using a display which only supports smaller resolutions, you will need to configure 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 configuration of your secure 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 configuration and hotkey choice.

• 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 actioned upon exiting the

OSD. See page 12 .

Using with dual head computers

Dual head computers 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) for use with Windows or Linux.

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 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. No configuration is required.

Linux operation

Video, USB and audio connections are required to each channel: primary and secondary.

No drivers are required.

USING THE OSD

The OSD deals with settings that may need to be occasionally changed after the initial commissioning process, such as video, channel and USB settings. The various options within the OSD are divided into four distinct pages.

To enter the OSD

1 On the console keyboard, enter the following in succession:

• Left Ctrl then Right Ctrl then o (upper or lower case is accepted)

The menu will appear in the bottom left part of the primary screen.

Auto Scaling

Maintain aspect ratio - The channel video aspect ratio will be maintained when the user resizes the window. This will result in a black bar being displayed where the window aspect ratio differs.

Ignore aspect ratio - The channel video will be resized to fit the window and thus may become distorted.

None - The channel video size and aspect ratio will remain the same regardless of the window size.

Window Border

Defines whether a border is displayed for each channel window, or not.

If displayed then the color of the border is determined by the Channel

Color (see Channel Settings).

Presentation Mode

Full - When switching to a new channel from the front panel, it will be displayed in full screen.

Partial - Tile Mode will be used when switching to a new channel.

Off - When switching to a new channel, the currently selected method of presentation will be retained.

Set Output Resolution

Choose the required output screen resolution. If two displays are connected, then the same resolution will be used for both.

IMPORTANT: Ensure that the display(s) support the desired output resolution. If not, the display will go blank. To resolve, change the output resolution using a hotkey: “L Ctrl | R Ctrl | D | # ”, where # is 1 to 8.

Dual Head Channel

Allows you to specify connection to 1 or 2 dual head PCs, rather than the default single head PCs. The default ‘None’ setting means that the input channels are treated as single head, but the channels 1+2 and 3+4

may be designated as dual heads. Please refer to page 11

for dual head connections.

PIP Switching Mode

Picture in Picture mode. When enabled, the mouse will pass behind any smaller window displayed on top of the active one. Mouse switching will only occur when moving outside the active window boundary.

This page is intended to aid technical support. It displays the version number for the System and Video Controllers, plus Front Panel firmware. It also displays the FPGA version and System Type: (Secure or

Commercial).

Note: The AVS-1124 will always be stated as Secure.

Operation

The secure multi-viewer switch allows the user to view the video outputs of up to four host computers simultaneously, either on a single display or dual displays. Keyboard and mouse control is assigned to a single host computer at a time and is switchable using a

number of methods (see page 19).

Hold audio Channel buttons Status display

Audio Hold

The Audio Hold button prevents switching the audio port when changing the other console peripherals (keyboard, mouse, video) to another computer channel. This function is useful when you need to listen to the audio from one computer while working on another.

Using the front panel computer channel buttons, first connect the console peripherals to the computer from where the audio feed is required. Press the Audio Hold button on the front panel. Then press the channel button for the computer that is required for the other peripherals. The audio association will be signalled by the right indicator on each channel’s front panel push button.

To release the audio from hold status, press the Audio Hold button again.

Status display

The secure nature of the switch entails that all USB communications are uni-directional. This means that the keyboard num, caps and scroll lock indicators will not work.

Therefore, the secure switch provides such indications on the optional remote control unit.

The status display also shows the current channel number; the channel from which audio is being derived and also the remote control unit status.

Displaying windows

You can choose how to view the windows of the various host computers.

Full screen

Shows a single window on the whole screen.

• On the keyboard, press and release: L Ctrl | L Ctrl | f

Note: This means press and release the following keys:

Left Ctrl then Left Ctrl then f

For dual displays, it applies to the screen with cursor focus.

Tile (quadrant) layout

Shows four windows on the display in a quadrant.

• On the keyboard, press and release: L Ctrl | L Ctrl | q

1 2

3 4

Focus layout

One window is shown at a larger size with the other windows scaled down and located on the right-hand side of the screen.

• Press: L Ctrl | L Ctrl | s

Rotate the mouse thumbwheel to move the focus between the windows. If thumbwheel switching is disabled (see USB Settings

page 15), then either select focus channel from front panel or

window within System mode.

Custom layouts

If custom layouts have been saved (see page 20), you can select one as follows:

• Press: L Ctrl | L Ctrl | F# ( where F# is the required function key: F1 to F8)

Dual displays

When dual displays are used in

Extend Display Mode (page 13), the

secondary display will remain blank until you drag a window on it or select a preset layout that uses it. The

Focus layout is recommended for dual displays, as per the diagram to the right.

Channel buttons

Status display

• In any of the multi-view layouts, hold the Left Ctrl button on the keyboard and move the mouse cursor across the boundaries of the display windows. Release Left Ctrl when to enable keyboard control of the selected computer.*

* The mouse method relies on absolute mouse mode, which can be enabled and disabled by the user to match their own preferences and to ensure compatibility with their computers.

To use absolute mouse mode, press: L Ctrl | L Ctrl | F11 | c

To use relative mouse mode, press: L Ctrl | L Ctrl | F11 | b

In Relative mouse mode, channel switching is restricted to either the front panel buttons or the scrolling the mouse thumbwheel.

Managing windows

In everyday use, the secure 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 five-button mouse, select either of the side buttons.

Note: The mouse must be set to use Absolute Mode (see page 15).

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 secure switch.

To return to user mode

• Press L Ctrl | L Ctrl | u to return to user mode.

• On the mouse, either click the scroll wheel, or for a five-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 predefined layouts and adjust it to suit your requirements. These layouts can be selected before or after entering system mode:

• For tile (quadrant) 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 predefined 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 fill 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 defined window you can use either of the following:

• To fill with a fixed aspect ratio: L Ctrl | L Ctrl | F11 | w

• To fill with a non-fixed aspect ratio: L Ctrl | L Ctrl | F11 | y
