Description
The SM20N-N is a 2-port keyboard and mouse (KM) switcher designed to let operators share a single set of peripherals across two isolated host computers. It provides real-time KM interaction while preserving electrical isolation between hosts and connected devices – the device maintains separate displays per computer and consolidates control peripherals. The design reduces the need to provision dedicated peripheral sets for each machine.
The SM20N-N supports copy and paste text transfer between connected computers using standard keyboard or mouse copy commands. Key features include USB keyboard and mouse I/O, 3.5 mm stereo audio and microphone jacks, and isolated host ports to maintain security boundaries. The unit implements secure peripheral sharing without requiring a network connection between hosts for text transfers.
From a technical perspective the SM20N-N is a two-source KM switcher supporting USB Type A console ports and USB Type B host ports, plus 3.5 mm audio and microphone jacks. It operates across 0 to 40 degrees C and stores from -20 to 60 degrees C and supports Windows, Linux and macOS for driver and interoperability needs. Product certifications include CE, RCM, FCC class B, VCCI, TUV US and TUV Canada and the unit ships with a 2 year warranty and a 10 year product life-cycle.
Connectivity includes direct console ports for keyboard and mouse (USB Type A), console audio and mic 3.5 mm jacks, and matching host-side USB Type B and 3.5 mm jacks. The SM20N-N requires a 12V DC, 1.5A external power supply and accepts 100 to 240V AC input via the included adapter. The switch supports the host console arrangement common in broadcast, lab and secure workstation installations and integrates with standard USB input devices and analog audio peripherals.
Typical deployments include secure operator workstations, laboratory systems where hosts must remain isolated, and broadcast control rooms requiring shared KM control across multiple machines. Because text copy works without network connectivity, the SM20N-N is suitable where file transfer is restricted but clipboard text exchange is required. The unit supports segregated displays per host so each computer can retain its native screen arrangement while peripherals are shared.
Installation is straightforward with USB Type A console connections and USB Type B host connections, plus standard 3.5 mm audio wiring. The unit is desk-friendly in its compact footprint and uses an external 12V power adapter for easy placement – no internal power wiring is required. Firmware and driver updates are applied according to vendor instructions and routine operation is controlled via the front-panel switching or standard hotkey sequences.
