Fast multi-monitor, multi-system control

View and operate two 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. 

Secure KVM control

To ensure sensitive information remains protected, Extio 3 features built-in protections to prevent security gaps, and doesn’t require software to be installed on the source system. 

  • Advanced Encryption Standard (AES) to encrypt signals between transmitters and receivers 
  • Password and user management with Microsoft® Active Directory® 
  • 802.1x port authentication and IGMPv3 to prevent unauthorized devices from accessing your network 
  • Syslog support to monitor and record KVM device and user activity

High availability & redundancy

Extio3 Zoomed in

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. 

The ultimate IP KVM for Broadcast and Media

Working with standard COTS network switches, Extio 3 IP KVM extenders offer broadcast environments a best-in-class KVM extension and switching solution over IP that is scalable and cost-effective. With Extio 3’s Aggregator Mode, you can access up to two systems simultaneously, and switch between sources with just a single keyboard and mouse.
