NetController 16-Port Console KVM switch. Cost effective and highly flexible system for controlling multiple computers from a single keyboard, monitor and mouse. Directly connect up to 16 computers, or increase the number of connected computers to up to 256 by daisychaining up to 15 B042-Series KVM switches. Switch between connected computers via Pushbutton, on screen display (OSD) or Hotkey commands. Connect computers to the KVM using a Tripp Lite P780-Series USB/PS2 Combo KVM cable kit.

Password feature provides additional security to prevent unauthorized access to connected computers. Rackmount hardware is included with the unit, and is designed for easy, one person installation. Fits into any rack from 27 to 42 inches deep, and can be installed in a 2-post rack using Tripp Lite's B019-000. Compatible with all major operating systems. Constructed of heavy-duty steel housing.
