Description

The SK21PH-N is a 2-port KVM switch that allows a single keyboard, video, mouse and audio set to be shared between two computers. It supports DP and HDMI console connections and delivers UHD 4K video up to 3840×2160 at 30 Hz. The unit is designed to simplify desktop workflows and reduce the need for duplicate peripheral sets.

Key features include dual-source switching, USB keyboard/mouse support, stereo audio connectivity and an integrated clipboard/file copy function for transferring data between connected hosts. The KVM supports standard USB Type A console devices and USB Type B host connections, plus 3.5 mm audio jacks. The built-in clipboard and file transfer works without a network connection and uses standard copy/paste commands.

Performance specifications include support for DisplayPort 1.2 and HDMI 1.4 signaling on the respective models with a maximum supported resolution of 3840×2160 at 30 Hz. The switch operates from an external 12 V DC, 1.5 A power supply and accepts 100 to 240 V AC input via the included adapter. Environmental ratings are 0 to 40 C operating temperature and 0-80% RH non-condensing humidity.

Connectivity options cover one console display (DP or HDMI), two computer display ports (DP/HDMI depending on the connected host), USB Type A console ports for keyboard and mouse and USB Type B host ports. Stereo audio input and output are provided via 3.5 mm jacks; the SK21PH-N does not provide a microphone jack on the console. The switch is compatible with Windows, Linux and macOS systems and fully certified to CE, RCM, FCC Class B, VCCI and TUV standards.

Typical use cases include trading desks that require rapid switching between systems, control rooms that consolidate operator workstations and office environments that need to save desk space and peripheral costs. The clipboard/file transfer feature is useful for copying text and files between machines without network configuration. Multi-monitor support is available in dual-head models for workflows that require screen duplication or extended desktop arrangements.

Installation is straightforward with plug-and-play USB and display connections and an external power adapter. The compact 177 x 82 x 35 mm enclosure and 0.52 kg weight make it easy to place on a desk or inside a small equipment bay. The unit ships with a two-year warranty and a 10-year product life-cycle for long-term deployments.
