Introduction

WELCOME
Thank you for choosing the ADDERView™ AVS-4128 secure switch for sharing single or dual head video, USB keyboard and mouse, plus analog audio between up to eight host computers spanning multiple security classification levels. Video resolutions up to 3840 x 2160 @ 60Hz are supported and all video connections can be DisplayPort™ or HDMI®.
The standard configuration allows the single-head outputs of any two hosts to be displayed on the dual video displays, in any order, with keyboard and mouse focus being switchable between them:

Alternative modes also support dual-head host connections, see “Appendix B – Alternative layouts” on page 19.

Free-Flow
To simplify switching the keyboard and mouse between the hosts currently outputting to the two video displays, you can use the Free-Flow feature (see page 13). When enabled, keyboard
and mouse focus follows the mouse as it moves across monitor edges.

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 of keyboard and mouse focus between currently selected host computers (configurable Free-Flow mode). Simply move the mouse between displays.
• 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. Firmware integrity is verified through a self-test procedure during power up. Detection of a critical failure disables the device and provides a clear visual indication to the user.

Safety
Please refer to the safety booklet provided in the box before use of this product.

TAMPER-EVIDENT LABELS
The secure switch models and also the smart card reader use holographic tamper evident labels to provide visual indications in case of an enclosure intrusion attempt. When opening product packaging inspect the tampering evident labels. If for any reason one or more tamper-evident label is missing, appears disrupted, or looks different than the example shown here, please call Technical Support and avoid using that product.

Operation

Front panel channel switching
The button toggles the focus between the left and right video displays (and the host computers that they are connected to).
The button illuminates in two halves to represent the left and right video displays. When the right side of the button is lit, this means that the keyboard and mouse are connected to the host computer that is linked to the right video display. Pressing a channel button will cause the new channel to be output to the display that currently has focus.

Note: If you are using a single video display, leave the button lit on its left side. `

Free-Flow
Adder Free-Flow allows you to automatically switch between host computers simply by moving the mouse across the edge of the screen. When enabled, keyboard and mouse focus follows the mouse as it moves across monitor edges. You’ll notice that the focus button reflects the current cursor position.

Notes

• When used with dual head displays connected to computers running older versions of Windows, it may require looping through the displays twice to effect a switch. The problem may be resolved by installing the Dual Monitor driver available from Adder.com
• Upon switching, the operator is advised to check the front panel display to confirm the currently selected channel.
• The Free-Flow feature is disabled by default and a factory reset will return it to a disabled state.

This feature requires the mouse to be used in absolute mode so that the switch can determine its exact position on each video display, rather than the default relative mode.
Note: Older versions of Linux do not support Absolute mode, so cannot be used with Free-Flow.

• To enable Free-Flow
  

  • Select absolute mouse mode: Press Left Ctrl then Left Ctrl then F11 then c

• To disable Free-Flow

  • Select relative mouse mode: Press Left Ctrl then Left Ctrl then F11 then b

Guard mode
Once Free-Flow is enabled, Guard mode whenever you wish 12 to switch to another computer, simply hold Ctrl down the Left Ctrl key on the console keyboard as you move the mouse pointer from the boundary of one screen towards that of the next. The channel should change as the pointer crosses the boundary. The necessity to hold down the Left Ctrl key is called Guard Mode and is there to prevent accidental switching. If required, you can disable guard mode, as discussed on page 16.

Audio hold
This front panel button (also replicated on the optional remote control unit) allows you to take the audio output from one computer while operating on another.

To use audio hold

1. Use any of the switching methods to choose the computer whose audio you wish to hear.
2. Press the Audio Hold button, either on the secure switch front panel or on the optional remote control unit.
3. Switch to the computer that you wish to use.

The audio feed to the speakers (attached to the secure switch) will continue to feed from the initially connected computer.

Status display
The status display shows the current channel number, channel name (if configured), audio channel and hold status, plus security classification (if configured). It also indicates whether the switch is under remote control.

The channel names and security classifications can be altered using Terminal mode – see “Appendix A – Terminal mode configuration” on page 16.
The RC symbol indicates that an external device is connected to the remote control port. Refer to the remote interface manual, MAN-000022 for details.

Channel indications
You can optionally assign indicator colors to each computer channel so that each front panel button illuminates accordingly.
The channel indicator colors can be altered using Terminal mode – see “Appendix A – Terminal mode configuration” on page 16.

4. toggle copy/paste support
   Copy and paste are permanently disabled on secure switches.

Appendix B – Alternative layouts
This section lists the various ways that host computers and video displays can be arranged on the switch. The keypresses that enable each mode need only be enacted once to set the configuration and will persist through complete power cycles. A factory reset operation will return to the Standard eight-host single-head layout.

Note that each layout uses Absolute mouse mode. If the uses changes to Relative mouse mode, then the unit will be returned to the default eight-host single-head layout.
Other bespoke layouts can be created for you by Adder Professional Services on request.

Default eight-host, single-head, dual-display layout
The standard layout allows you to control up to eight host computers and view their video outputs on either single or dual displays. When dual displays are used, each display can show the video output from any of the connected host computers, as selected either by front panel switches or keyboard hotkeys (see Appendix C on page 21). If Free-Flow is used for automated switching of focus between the two displays, they will be assumed to be arranged side-by- side, with the primary display on the left side.

To configure this layout
If the switch has been used in any other configuration, you can restore the standard layout with the following keypress sequence:

Left Ctrl then Left Ctrl then F11 then F1

(Note: F11 and F1 are function keys)

Eight-host, single-head, single-display layout

This variation is similar to the standard layout above, except that only a single video display is used.

Notes:

• The button should remain with its left indicator lit.
• Free-Flow is not enabled.

To configure this layout

If the switch has been used in any other configuration, you can restore the standard layout with the following keypress sequence:

• Left Ctrl then Left Ctrl then F11 then m (Note: F11 is a function key)

Eight-host layout with top/bottom displays
This layout operates as per the standard 8-host arrangement except that the displays are treated as being arranged one above the other for the purposes of Free-Flow switching (with the primary display at the top).

To configure this layout
Use the following keypress sequence:

Left Ctrl then Left Ctrl then F11 then F2
(Note: F11 and F2 are function keys)

One dual-head host plus six single-head hosts
This layout provides hybrid dual-head and single-head operation which permits one host to present two video channels while the other six supply a single video channel each. When channel 1 is chosen, its dual outputs will be shown on the two displays. When any other channel is chosen (except channel 2, which is not used), its output will be sent to either the left or right display, as determined by the current setting of the button (see page 13).
If Free-Flow is used for automated switching of focus between the two displays, they will be assumed to be arranged side-by-side, with the primary display on the left side.

To configure this layout
Use the following keypress sequence:

Left Ctrl then Left Ctrl then F11 then F3
(Note: F11 and F3 are function keys)

Eight single-head hosts with additional fixed display
This layout is particularly useful if an operator needs to continually monitor a critical source while also switching between other host computers. The first host computer provides its primary video output directly to the left- most of the three displays. Its secondary video output is connected to port 1 while up to seven other single-head hosts are connected to the remaining ports.

The primary output of host 1 is permanently displayed. Switching between all other channels proceeds as normal (see page 13).

If Free-Flow is used for automated switching of focus between the three displays, they will be assumed to be arranged side-by-side, with the secondary display on the far right side. Note: The externally connected monitor must have the same native resolution of the primary display that is connected directly to the switch.

To configure this layout
Use the following keypress sequence:
Left Ctrl then Left Ctrl then F11 then F7 (Note: F11 and F7 are function keys)

Four-host dual-head layout
This layout allows you to control up to four host computers and view their video outputs on dual displays. Each host is connected to two ports: host 1 to ports 1 and 2, host 2 to ports 3 and 4, and so on. On the front panel only four of the channel buttons are used: button 1 selects channels 1 and 2 (host 1), Button 3 selects channels 3 and 4 (host 2), etc.
When moving the cursor between the two displays, they will be assumed to be arranged side-by-side, with the primary display on the left side.

To configure this layout
Use the following keypress sequence:

Left Ctrl then Left Ctrl then F11 then d (Note: F11 is a function key)

Appendix C – Hotkey commands

Alternative layout presets (see Appendix B)

• Default eight-host, single-head, dual-display layout L CTRL | L CTRL | F11 | F1
• Eight-host, single-head, single-display layout L CTRL | L CTRL | F11 | m
• Eight-host layout with top/bottom displays L CTRL | L CTRL | F11 | F2
• One dual-head host plus six single-head hosts L CTRL | L CTRL | F11 | F3
• Eight single-head hosts with additional fixed display L CTRL | L CTRL | F11 | F7

Note: The hotkeys assume use a of US keyboard.

Note: Altering mouse speed is only available in Absolute mode.
Use main keyboard + and – , not the numeric keypad (see note below).

Note: The switch takes 5 seconds before Upload mode becomes active.

Using + and – hotkeys
The + and – keys located on the keypad section (on the right side) of your keyboard are NOT supported for use as hotkeys. For hotkey functions such as mouse speed adjustment, use only the + and – keys that are located in the main keyboard section, just to the left of the backspace key. Note also that on non-QWERTY (US/UK) keyboards, these two keys may not be labeled as + and – however, their functions as + and – hokeys remain valid.
