Multi-Monitor KM Switches for Control Room Workstations


Improved Situational Awareness with Multiple Computer Control

A streamlined workspace with improved desktop ergonomics is essential to improve operator response times. That's why operators in public safety, broadcasting, defense, and transportation as well as stockbrokers rely on Multi-Monitor KM Switches. Hardware-based, they offer reliable operation that provides the ability for a dispatch operator to switch between up to eight machines simply by moving the mouse across the desk monitors. Black Box offers with Freedom II and TC Series two multi-monitor KM switches with Glide-and-Switch Technology for trading workstation and control rooms.
