Description

The ATEN CS1142D4 is a 2-port, dual-display DVI Secure KVM Switch certified to PSD PP v4.0 (NIAP), purpose-built for defence, intelligence, government, and high-security environments where strict data separation between computers of different classification levels is mandatory. It allows a single user to share one keyboard, mouse, dual DVI monitors, and speaker set across two computers, with always-on chassis intrusion detection that permanently disables the switch if physical tampering is detected. Non-reprogrammable firmware, unidirectional data flow, automatic keyboard/mouse buffer purging on port switch, and strict audio filtration ensure air-gap-level security without compromising usability.

The CS1142D4 supports resolutions up to 2560x1600 via DVI Dual Link, or up to 3840x2160 @ 30 Hz when used with ATEN DVI-to-HDMI KVM cables. Port switching is hardware-only via front-panel pushbuttons or an optional Remote Port Selector — no software switching is permitted. This variant does not include a CAC (Common Access Card) reader, making it ideal for deployments where smart-card authentication is managed separately. In stock and ready to ship from iptrading.com.au — order now for fast dispatch.

Features

- PSD PP v4.0 (NIAP Certified) — meets the most stringent government and defence security standards for peripheral sharing devices
- Always-on chassis intrusion detection — switch is permanently disabled if physical tampering is detected
- Tamper-evident labels — visible indication of any attempt to access internal components
- Non-reprogrammable firmware — eliminates firmware-level attack vectors
- Unidirectional data flow — ensures no data can traverse from console peripherals to a non-selected computer
- Automatic keyboard/mouse buffer purge on port switch — no residual data retained between sessions
- Restricted peripheral connectivity — non-authorised HIDs and video connections are rejected automatically
- Configurable Device Filtration — administrators can whitelist specific USB HID devices
- Administrative KVM audit logging — authorised administrators can review port activity logs
- Strict audio filtration — prevents audio-channel data leakage between classified systems
- Hardware-only port switching — no software or hotkey switching permitted, eliminating software-level attack surface
- Video DynaSync™ — eliminates boot-up display issues and optimises resolution when switching between sources
- LED indicators for peripheral filtering status and overall KVM security state
- Suitable for government agencies, military, intelligence, healthcare, banking, and any organisation handling classified or sensitive data

FAQs

Q: What does PSD PP v4.0 (NIAP) compliance mean for this KVM switch?
A: PSD PP v4.0 refers to the Protection Profile for Peripheral Sharing Devices, Version 4.0, as evaluated and certified by the National Information Assurance Partnership (NIAP). It means the CS1142D4 has been independently validated to meet stringent security standards for use in classified or sensitive government, defence, and intelligence environments where computers of different security classifications must share peripherals without any data leakage between them.

Q: What happens if someone tries to physically open or tamper with the switch?
A: The CS1142D4 features always-on chassis intrusion detection. If physical tampering is detected — such as an attempt to open the casing — the switch is permanently rendered inoperable. Tamper-evident labels also provide a visible indication of any interference with internal components.

Q: What is the difference between the CAC and Without CAC variants?
A: The CAC (Common Access Card) variant includes an integrated smart-card reader, enabling hardware-based user authentication via government-issued smart cards — common in US DoD and federal agency deployments. The 'Without CAC' variant (CS1142D4) does not include this reader and is suited for environments where smart-card authentication is handled by a separate device or is not required.

Q: Can I switch between computers using software or hotkeys?
A: No. The CS1142D4 is restricted to hardware-only port selection via the front-panel pushbuttons or an optional Remote Port Selector (RPS). Software-based switching is deliberately prohibited as part of its PSD PP v4.0 security design, eliminating the risk of software-level attacks manipulating the KVM port.

Q: What video resolutions does the CS1142D4 support?
A: The switch supports up to 2560 x 1600 via DVI Dual Link and up to 1920 x 1200 via DVI Single Link. When used with ATEN's DVI-to-HDMI KVM cables, it can support resolutions up to 3840 x 2160 @ 30 Hz (UHD/4K). Video DynaSync technology optimises display resolution detection when switching between computers.

Q: Can I purchase the ATEN CS1142D4 in Australia through IP Trading?
A: Yes. The ATEN CS1142D4 Secure KVM Switch is available from iptrading.com.au with stock on hand and fast dispatch.
