Secure (PPs 4.0), 4-port DVI Multi-view KVM Switch

Secure (PPs 4.0), 4-port DVI multi-view KVM switch 

supporting two HDMI screens (one of which is a dedicated multiview preview screen to view all 4 video sources simultaneously), with analog audio support 

---

• Automatic switching between ports without the need to press any buttons – simply move the mouse between windows
• Dual HDMI-video outputs where the second output can optionally extend the desktop
• Analog audio with Hold feature
• Clear channel identification to reduce the chances of operator error by displaying a user defined name for each channel on the status display – the color of the channel indicators may also be configured

AdderView AVS-1124 secure KVM switch enables a keyboard/video/mouse plus audio console to be shared between different classification level computers. Designed for superior usability, the KVM switch features configurable LED buttons and a real-time status display.

AVS-1124 is designed to prevent sensitive data leakage and data storage in the KVM switch. Using features such as uni-directional data paths, anti-tampering labels, and non-reprogrammable firmware, AVS-1124 actually combats a range of potential threats.

The user can choose to view the output of any computer on either connected video display or view all four outputs on one display.

Hardware Anti-Tampering
Holographic anti-tampering labels protect the product’s enclosure, providing a clear visual indication if it has been opened or compromised. The secure KVM switch and also the smart card reader use holographic tamper evident labels to provide visual indications in case of an enclosure intrusion attempt.

Uni-Directional Keyboard and Mouse Data Paths
Uni-directional optical diodes ensure data paths travel in only one direction, thus preventing data leakage through shared peripherals. A uni-directional structure also protects against timing analysis or forced malfunction attacks and prevents computers influencing the operation of any common circuitry.

Uni-Directional Video
Computer video input interfaces are isolated through use of separate electronic components and power. The display is isolated by a dedicated, read-only, EDID (Extended Display Identification Data) emulation for each computer. Access to the monitor’s EDID and MCCS (Monitor Control Command Set) commands are blocked.

Uni-Directional Audio
Enforces computer-to-speaker one-way flow of sound through uni-directional optical data diodes, This prevents eavesdropping and line-in re-tasking by blocking speaker-to-computer communication.

No Shared RAM between Channels
The keyboard and mouse processor is powered down and reset at each switchover to thwart shared RAM leakages. All data buffers are actively cleared once they have been used.

Non-Reprogrammable Firmware
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.

Restricted USB Function
The USB ports will only accept HID (Human Interface Devices), such as keyboards and mice. Other devices, such as USB storage drives, are actively prohibited.

CAC Support
CAC support is provided through the use of the optional AS-4CR secure card reader (purchased separately – see listing below), which allows a single user’s smart-card to simultaneously authenticate with up to 4 isolated computers.

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 KVM switch is under remote control.

Audio Hold
Assign the audio port to a specific computer while switching the KVM switch to another computer. 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. Useful when a user needs to listen to audio from one computer while working on another.

Switching Between Channels
• Front-panel buttons
• Optional remote control unit (AS-4RCU)
• Keyboard shortcuts
• Free-Flow feature switches channels as the mouse pointer crosses a video display boundary
Multiple techniques are employed to ensure that no crosstalk can occur between the connected computer channels.

Optional USB Port Expander
The USB port expander (purchased separately – see listing below) provides an additional USB port for applications that require a touch-screen device in addition to keyboard and mouse. It also provides advanced  protection incorporating physical and programmed protection of computer USB ports.

Optional Remote Control Unit
The optional remote control unit (purchased separately – see listing below) allows the operator to change channels when the secure KVM switch unit is not within reach. 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.

Displaying windows
The user can choose how to view the windows of the various host computers:
• Full screen – Shows a single window on the whole screen.
For dual displays, it applies to the screen with cursor focus.
• Tile (quadrant) layout – Shows four windows on the display in a quadrant.
• 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.
• Custom layouts

Dual displays
When dual displays are used, the secondary display will remain blank until the user drags a window on it or selects a preset layout that uses it. The secondary display can be configured to be a duplicate of the primary, or to display the video extended across both the primary and secondary displays, in which case the user can move windows between displays and define presets that utilize the extended desktop.

Features ane Benefits
• Error indications – The secure KVM switch continually runs integrity checks throughout its circuitry – If any unexpected behavior is detected the secure KVM switch will immediately cease operation, lock all ports and provide operator feedback by flashing all of the channel button indicators
• Channel identification – Reduce the chances of operator error by displaying a name for each channel and its security classification on the E-paper display. The color of the channel LED may also be configured to reflect the security classification
• Video performance – Up to 1920×1200 at 60Hz for graphics intensive applications requiring very high quality
• NIAP PPs 4.0 Certified
• Assembled in the USA
• TAA Compliant
