KVM Switch ATEN 16-Port USB 3.0 4K HDMI CS18216-AT-G

The ATEN CS18216 16-Port USB 3.0 4K HDMI KVM Switch enables control of up to 16 HDMI-equipped computers from a single USB keyboard, USB mouse and one HDMI monitor. It supports 4K DCI resolution (4096 x 2160 @ 60Hz) for high-fidelity video, includes a built-in USB 3.1 Gen 1 hub with data rates up to 5 Gbps, and is housed in a robust metal chassis. The unit supports cascading up to two levels to manage up to 256 computers from a single console and allows multi-display setups by stacking up to eight units to drive up to eight monitors. Two-level password authorization and multiple port selection methods (front pushbuttons, hotkeys, RS-232 commands and OSD) provide flexible control and access security.

Advantages

Its cascading and stacking capabilities expand system scale without additional consoles. The device’s metal housing and included rack-mount kit make it suitable for professional rack installations, and the two-level password protection secures access to connected computers.

Recommendations

For reliable 4K@60Hz performance, use high-quality HDMI 2.0 or higher cables and ensure connected displays and source devices support the stated resolution. When deploying multiple units, follow ATEN’s cascading and stacking procedures in the user manual and configure two-level passwords to limit access and improve security.
