Comutador KVM ATEN 4 portas USB HDMI com CAC, 4K UHD 3840x2160@60Hz, caixa metálica

ATEN PSD PP v4.0 Secure KVM Switch CS1184H4C is a 4‑port USB HDMI KVM switch designed for environments that require strict peripheral isolation and controlled sharing. It allows a single USB keyboard and mouse, an HDMI monitor, speakers and a Common Access Card (CAC) reader to be shared between four computers of different security levels while enforcing protections to prevent data leakage. The unit supports 4K Ultra HD (3840×2160 at 60 Hz), is housed in a metal chassis finished in black, and is AC powered. It is certified to the PSD PP v4.0 Protection Profile, providing evaluated peripheral sharing controls for secure workstation setups.

Advantages

The switch provides mandatory isolation and unidirectional data flow between connected computers and shared peripherals, configurable device filtration for USB authentication and HID devices, strict audio filtering, and always-on chassis intrusion detection that renders the device inoperable if tampering is detected. Manual port switching via front-panel pushbuttons or a Remote Port Selector (RPS) prevents accidental or unauthorized automatic switching, supporting secure multi-system access with minimal user complexity.

Suitable for

• Government and defense workstations requiring evaluated peripheral sharing
• Intelligence and secure facilities with multi-classification systems
• Healthcare environments handling protected health information across networks
• Banks and financial institutions needing separation between systems
• Control rooms or operators managing multiple isolated systems

When it may not be suitable

This KVM switch is intended for high-security environments and enforces manual switching only; it may not be suitable for setups that require automatic or software-based switching between computers. Environments that do not require evaluated security controls or where extensive USB device passthrough without filtration is needed may find its device filtering limitations restrictive.

How to use

Install the unit on or under the workstation and connect each computer to the corresponding USB and HDMI ports. Connect a single USB keyboard and mouse, an HDMI monitor, speaker set and CAC reader to the front or designated console ports. Use the front-panel pushbuttons or the Remote Port Selector (RPS) to switch active computer focus; the device enforces peripheral filtration and audio policies automatically when switching. Ensure AC power is connected and the chassis tamper detection remains unobstructed to maintain evaluated security functions.

What to consider before purchase

• Requirement for PSD PP v4.0 evaluated peripheral sharing and physical tamper protection
• Need for manual-only port switching (pushbuttons or RPS) rather than automatic switching
• Whether USB device filtration and restricted passthrough meet your peripheral compatibility needs
• Required video resolution support (4K @ 60 Hz) and HDMI connectivity
• Physical dimensions, metal housing and weight for rack or desktop placement

Recommendations

For secure deployments, place the switch in a controlled physical environment, connect the CAC reader and required peripherals to the designated console ports, and train users to switch ports using the front-panel buttons or RPS. Regularly verify chassis intrusion status and apply administrative device filtration settings to allow only approved USB authentication devices and HID peripherals.
