Introduction
Safety
Please refer to the safety booklet provided in the box before use of this product.
WELCOME
Thank you for choosing a ADDERView™ AVS secure switch for sharing single or dual
head video, USB keyboard and mouse, plus analog audio between four computers
spanning multiple security classication levels. Separate models are available which
support single video displays for each channel or dual video displays throughout. In each
case you have a choice of either DVI or DisplayPort video operation.
Free-Flow
To remove the need to press channel
buttons when switching, you can use
the Free-Flow feature instead (see page
14). When enabled, you may switch
channels by moving the mouse across
monitor edges according to the video
layout. The front panel displays the
currently selected channel number.
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 channels (congurable Free-Flow mode)without the need
to press any buttons. Simply move the mouse between windows.
• 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.

are arranged in a default 2x2 grid and are
all connected directly to their respective
computers.The operator can view all
of the channel outputs simultaneously.
This arrangement requires the Free-Flow
feature (see page 14) to be used to
allow automatic switching of the console

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.
OPTIONAL EXTRA ITEMS
USB Port Expander
The USB Port Expander (part number: AS-UHF)
provides an additional USB port for applications
that require, say a touchscreen device in
addition to keyboard and mouse. It also
provides advanced protection incorporating
physical and programmed protection of
computer USB ports, as summarized below.
Protection features
• The expander physically mounts and locks on a standard USB port.
• Forced removal damages the USB port making it unusable.
• Accepts only USB HID devices (keyboards and mice) and blocks other HID devices.
• Hardcoded ASCII keyboard / mice characters.
• Incapable of processing any code other than HID-ASCII.
• Highly secure, read-only non-congurable chip.
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.

SWITCHING BETWEEN CHANNELS
• Press the required channel button on the front panel:
Operation
• When using the optional remote control
unit (AS-4RCU), select the required
channel from there:
• Use the Free-Flow feature to automatically switch channels as your
mouse pointer crosses a video display boundary.
Free-Flow
Adder Free-Flow allows you to automatically switch between target computers simply by
moving the mouse across the edge of the screen. This is most often used when separate
video displays are all connected directly to the computers; with only the keyboard,
mouse and audio being switched (also known as KM mode).With the multiple video
displays arranged in a grid, you can clearly see which display you are working on and the
direction in which you need to move the mouse in order to select the next.
The default display layout is 2x2, however, this may be changed to 4x1 by pressing:
Left Ctrl then Left Ctrl then F11 then F2.
To revert to 2x2 layout mode, use F1 at the end instead.
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
• Free-ow works for both single and dual head displays.
• 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 Right Ctrl then F11 then c
To disable Free-Flow
• Select relative mouse mode: Press Left Ctrl then Right Ctrl then F11 then b
Note: Free-Flow mode can also be enabled/disabled from terminal mode. Ensure that ‘video follow
mouse’ mode is enabled, otherwise only the USB and audio will switch. See page 19.
Guard mode
Once Free-Flow is enabled, whenever you wish to switch to another computer, simply
hold 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 17.

STATUS DISPLAY
The status display shows the current channel number,
channel name (if congured), audio channel and hold
status, plus security classication (if congured). It also
indicates whether the switch is under remote control.
REMOTE CONTROL UNIT
When a remote control unit is connected, the front panel buttons will have no effect,
however, the button indicators will continue to reect the current channel selection, as
determined by button presses on the remote control unit.
Adding and removing an RCU
An RCU may be added or removed at any time:
• Once connected, associate the RCU by pressing any key.
• Once disconnected, power cycle the switch unit.
ERROR INDICATIONS
The secure switch continually runs integrity checks throughout its circuitry. If any
unexpected behavior is detected the secure switch will immediately cease operation, lock
all ports and provide operator feedback by ashing all of the channel button indicators.
Following an error indication: Remove power from the unit, check all connections and
peripheral devices before re-applying power to the secure switch.
KM CONFIGURATION
When Free-Flow is enabled (see page
14), it is possible to use the switch in KM
Conguration, where the video displays
are arranged in a default 2x2 grid and are
all connected directly to their respective
computers.This allows the operator to
view all channel outputs simultaneously. No
further conguration is required.

and also 9 - exit terminal mode.
asset management - [option 0 from the top level menu]
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.
