UltraMatrix X-Series is a powerful and versatile KVM switch with the ability to connect up to 256 users to as many as 1,000 computers by cascading multiple units. Units connect together with a bus connection to make a seamless and truly scalable KVM matrix solution. Its modular architecture makes the switch simple to install, expand, and maintain. The unit supports hot-swappable capabilities and permits plug-in cards to be removed or changed at any time without powering off the system, minimizing detrimental system downtime than can potentially hurt productivity.

Available in three models:

  • 4 users
  • 8 users
  • 16 users

All models are compatible with any operating system and support peripheral serial devices. When accessing a serial device the on-screen display becomes a color VT220 terminal. An Advanced Visual Interface is used to configure the unit, name computers, select computers, and display computer connections. Security features are included to prevent unauthorized configuration and access
