The SK21H-N is a 2-port HDMI KVM switch that enables a single keyboard, mouse, monitor and audio set to be shared between two computers. It supports UHD 4K resolutions up to 3840×2160 at 30 Hz and uses HDMI 1.4 for video transport. The unit is designed to simplify multi-computer workflows while saving desk space and reducing peripheral costs.
Built-in features include USB keyboard and mouse switching, 3.5 mm audio and microphone jacks, and a clipboard/file transfer function that allows copy and paste of text and files between connected computers without a network connection. The KVM supports standard USB Type A console connections and USB Type B computer connections for peripheral I/O. Switching between sources is instantaneous and preserves keyboard and mouse functionality across systems.
Video performance supports HDMI 1.4 at resolutions up to 3840×2160@30 Hz. Audio is handled via analog 3.5 mm jacks for output and microphone input. The unit is powered by an external 12V DC, 1.5A power supply and accepts 100 to 240V AC input, enabling global deployment scenarios.
Connectivity includes one HDMI console port, two HDMI computer ports, USB Type A console for keyboard and mouse, USB Type B computer ports, and separate 3.5 mm audio and microphone connectors. Supported operating systems include Windows, Linux and Mac. The device is CE, RCM, FCC class B, VCCI, TUV US and TUV Canada certified and is BAA & TAA compliant for government use.
Typical applications include trading desks and control stations where operators need to access two systems from one workstation, IT support desks that require rapid context switching between machines, and laboratory or evaluation benches that consolidate peripherals. The clipboard and file transfer feature simplifies cross-system data movement without requiring network file shares.
Installation is straightforward – connect HDMI and USB cables between the KVM and each computer, attach console peripherals, and connect the external 12V power supply. The compact metal enclosure and standard dimensions make it suitable for desktop placement or integration into shallow racks or console trays. A two-year warranty and a 10-year product lifecycle provide long-term support and predictable maintenance.
