    Whether deployed as point-to-point extenders or as KVM over IP, KVM extenders offer the flexibility to adapt to your installations as demands change. With the power to create flexible, scalable, and secure KVM matrix-routing using standard network switches, Extio 3 enables you to easily expand your installations with confidence and without costly upgrades to help future proof your investment.  









    Fast multi-monitor, multi-system control


    View and operate four source computer systems from any Extio receiver unit and control them with a single keyboard and mouse set. Seamlessly shift control from one target source system to another simply by moving your mouse across a multi-screen desktop. 

    With Aggregator Mode, you can shift from the current desktop to the next by moving the mouse freely across multiple desktops. For an even more efficient way to control multiple KVM systems, the Tile View feature enables you to display up to four separate systems on one 4K or FHD monitor.

    Secure KVM control

    Secure distribution & monitoring

    A non-intrusive solution, Extio 3 doesn’t require any additional software installation on the source system. It also features multiple built-in safety protections to prevent security gaps in the safeguarding of sensitive information: 

    • Advanced Encryption Standard (AES) to encrypt KVM signals transmitted between transmitter and receiver units. 
    • USB encryption and device management to block or authorize USB 2.0 devices.
    • Integration with Microsoft® Active Directory® and with an IPSec (Internet Security Protocol) VPN client to ensure secure KVM extension over the internet.


    High availability & redundancy

    Extio 3 network connectors

    Build redundancy and fault tolerance into your installations. Supporting a distributed model of operation, Extio 3 removes single point of failure by storing all device settings and connectivity rules in each transmitter and receiver unit. Extio 3 appliances also feature two network interface ports that are configurable for link redundancy.
