Secure four-port KVM for defence and intelligence

The ATEN CS1184DP4 is a 4-port DisplayPort KVM switch built to meet the stringent security requirements of secure defence and intelligence installations. It allows a single console to control four isolated computers while maintaining strict data separation. The device is certified compliant with the PSD PP v4.0 Protection Profile by the National Information Assurance Partnership. It is not suited for buyers who need multi-monitor support or higher refresh rates.

Passive cooling with external power supply

The unit operates without internal fans, relying on passive thermal management and an included 3-prong AC power socket for stable operation. Front-panel access provides a single DisplayPort output, two USB Type-A ports and a mini stereo jack for immediate console connection. Rear-panel ports include four DisplayPort inputs, four USB Type-B computer links, four audio jacks and an RJ-11 connector. No acoustic or power-draw figures are published.

Certified isolation with bundled cables and firmware

The package supplies the necessary DisplayPort and USB cables to link four systems, plus a mini stereo audio cable for each port. Firmware is locked to the PSD PP v4.0 baseline, preventing unauthorised updates that could compromise isolation. The RJ-11 port supports an optional remote port selector for secure switching at a distance. Users who require keyboard-mouse emulation for non-standard peripherals should verify compatibility before deployment.

Questions about this item

How do I connect the four source computers to the CS1184DP4 and which step is often missed?

Plug each computer's DisplayPort output into one of the four rear DisplayPort female ports and its USB port into a matching USB Type-B female port; the step often missed is connecting all four USB Type-B cables so keyboard and mouse switching works on every port.

What maintenance or replacement will the CS1184DP4 need over time?

The unit has no user-serviceable parts or filters; if a DisplayPort female port or USB Type-B female port becomes damaged, the entire switch must be replaced.

What resolution limit appears first when running the CS1184DP4 continuously at its maximum?

The switch caps external output at 3840 x 2160 at 30 Hz, so sustained use cannot exceed that refresh rate at UHD resolution.
