AVS 2114 ADDERView Secure Desktop User Guide

AVS 2114 ADDERView Secure Desktop

Introduction

WELCOME
Thank you for choosing a ADDER View™ AVS secure switch for sharing single or dual head video, USB keyboard and mouse, plus analog audio between four computers spanning multiple security classification 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.
The secure switch can be used in two main configurations depending on the requirements of the installation:

KM configuration
The user console consists of keyboard, mouse and speakers. The video displays are arranged in a default 2×2 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 between channels.

KVM configuration
The user console consists of keyboard, mouse, speakers and also video display(s), which are all connected to the secure switch. The common video display(s) show the output of the currently active channel.

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 (configurable Free-Flow mode)without the need to press any buttons. Simply move the mouse between windows.
• 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.

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.

Installation

CONNECTIONS
All connections are made at the rear panel. Use only approved shielded cables, particularly for the video connections. Ensure that all connections are made before applying power.

Computer connections
The secure switch has four computer ports, each of which consists of: one (AVS 2114/4114) or two (AVS 2214/4214) video links, a USB link and an audio connection. Note: The secure switch can be used either with video display(s) connected to the console ports (KVM configuration) or alternatively with displays connected to each computer (KM configuration – see page 15) to allow the operator to view them all simultaneously.

The green indicator associated with each console port should be ON to signify correct communications with the peripheral device. The video indicator will flash on power up whilst the switch is reading the EDID from the display. As a security measure, once the video indicator is ON the switch will not read the EDID again unless the switch is power cycled.
Note: If dual link cables are connected together with a monitor capable of a higher resolution than 1920×1200, then the computer graphics card may auto-select a higher resolution, which may result in video artifacts.

AVS 2114 and 2214 units support single Link DVI video resolutions up to 1920 x 1200 @ 60Hz.
AVS 4114 and 4214 units support DisplayPort or HDMI video resolutions up to 3840 x 2160 @ 60 Hz.

Operation

SWITCHING BETWEEN CHANNELS

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 2×2, however, this may be changed to 4×1 by pressing: Left Ctrl then Left Ctrl then F11 then F2.To revert to 2×2 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-flow works for both single and dual head displays.
•  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 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.

KM CONFIGURATION
When Free-Flow is enabled (see page 14), it is possible to use the switch in KM Configuration, where the video displays are arranged in a default 2×2 grid and are all connected directly to their respective computers. This allows the operator to view all channel outputs simultaneously. No further configuration is required.

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.

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 reflect 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 flashing 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.
