Aten CS1144H4 4-Port USB HDMI Dual Display Secure KVM Switch PSD PP v4.0 / TAA

Description

The CS1144H4 is a PSD PP v4.0 compliant secure KVM switch designed to share a single keyboard, mouse, dual HDMI monitor setup and speaker between four isolated computer sources. It enforces strict data isolation and unidirectional data flow to prevent data leakage between networks of different classifications. The unit is TAA compliant and produced in Taiwan for secure deployments.

Security features include always-on chassis intrusion detection that renders the unit inoperable if tampering is detected, tamper-evident labeling, and non-reprogrammable firmware to prevent unauthorized modification. The KVM supports configurable USB HID device filtration and strict audio filtering to block unauthorized devices and audio data. Port switching is limited to front-panel pushbuttons or a Remote Port Selector to reduce attack surfaces.

Performance supports console video output up to 3840 x 2160 at 60 Hz for each display and uses ATEN Video DynaSync to optimize resolutions on source changes. Analog speaker output is supported for audio only and keyboard/mouse transmission data is automatically deleted after transmission and when port focus changes. Power input is 100-240V~, 50-60 Hz, 1A and typical power consumption is 7.2W at AC110V or 7W at AC220V.

Connectivity includes two HDMI console outputs, two USB Type-A console ports, a front-panel stereo speaker jack, four USB Type-B KVM ports, eight HDMI KVM ports and four KVM stereo jacks. A rear RJ-11 port is provided for an optional Remote Port Selector which is sold separately. LED indicators provide status for power, selected KVM ports, video and key lock and there is a semi-recessed reset button and a rocker power switch.

The CS1144H4 is suitable for high-security environments such as government, defense, intelligence, healthcare and financial institutions where data separation is mandatory. It supports administrative auditing of KVM log data and keyboard/mouse port filtering for granular control of HID devices. The secure switching model ensures operations remain compliant with PSD PP v4.0 standards.

Installation is straightforward with a rugged metal enclosure and simple front-panel controls that require no network connection for operation. The unit is designed for immediate secure deployment and low maintenance thanks to its non-reprogrammable firmware and tamper-evident design. The CS1144H4 delivers secure, reliable desktop isolation where enforced peripheral sharing is required.
