Introduction
Safety
Please refer to the safety booklet provided in the box before use of this product.
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 classication levels. Video resolutions up to 3840 x
2160 @ 60Hz are supported and all video connections can be DisplayPort™ or HDMI®.
The standard conguration 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:
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 (congurable Free-Flow mode). Simply move the mouse between displays.
• Clear channel identication to reduce the chances of operator error by displaying a
user dened name and security classication for each channel on the status display.
The color of the channel indicators may also be congured to reect the security
classication.
• 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 rmware or memory through any port. Firmware
is permanently stored in non-reprogrammable Read Only Memory (ROM) to prevent
modication. Firmware integrity is veried 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.

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.

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.
Channel 1 is applied to the left display; channel 3 is applied to the
right display, as conrmed by their respective left (1) and right (3)
illuminations of the channel buttons.The button is illuminated
on its right side, meaning that the keyboard and mouse are
currently linked to the host computer on channel 3. Any channel
button pressed at this stage would connect that computer to the
right display as well as the keyboard and mouse.
A single press of the button will shift the focus to the left
display. If the channel 4 button is now pressed, host computer
4 will be connected to the left display (as well as to the
keyboard and mouse). An optional press of the button will
shift the keyboard and mouse back to the channel 3 computer,
without affecting either of the video displays.
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 reects 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 MuMo (multi-monitor) driver available from Adder.com
• Upon switching, the operator is advised to check the front panel display to conrm 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

Once Free-Flow is enabled,
whenever you wish
to switch to another
computer, simply hold

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

These options are deal with the USB name (descriptor) that the secure switch uses to
identify itself to the connected computers. In order to avoid a standard descriptor being
used across numerous computers, serving as a marker for potential attackers, use these
options to enter a new custom tag (option 3), set it as the default (option 2) and send
it to the attached computers (option 5). Once a descriptor is set, it will be sent to the
computers at every power up.

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 congure 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 congure this layout
Use the following keypress sequence:
• Left Ctrl then Left Ctrl then F11 then F3 (Note: F11 and F3 are function keys)
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 conguration 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 congure this layout
If the switch has been used in any other conguration, 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)
Default 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 congure this layout
If the switch has been used in any other
conguration, you can restore the standard layout
with the following keypress sequence:
• Left Ctrl then Left Ctrl then F11 then m
