Securely switch between sources.

Maximum Security

Inverted signals control data relays to guard connections against outside intrusion. Each port has an isolated data channel and each unit uses non-reprogrammable ROM with no data leakage between ports. Isolated connections also prevent data leaks between secure ports and the outside world when accessing classified and public networks over the internet.

Secure EDID Learn and Video Emulation

The switch emulates a keyboard and mouse for each attached computer via a USB cable. Selected and non-selected computers maintain a connection with the unit's keyboard-mouse emulation controllers, allowing for ultra-fast switching and restricting the discovery of newly connected peripherals during switching. Emulation also prevents the direct connection between peripherals and connected computers.

Tamperproof Seals

Built-in tamperproof seals and a long-life internal anti-tamper battery keep devices secure.

Optional CAC Port

Add a Common Access Card (CAC) reader at point-of-sale in retail or for access in other industries.
