1. Overview
8 ports/16 ports HDMI USB KVM (Keyboard, Video, Mouse) Switches are control
units that allow access and control of up to 8 (DS-12910) or 16 (DS-12911)
computers from a single USB/keyboard, USB/mouse, and monitor console.
There are two convenient methods to access any computer connected to the
installation: (1) using the push button port selection switches located on each
unit’s front panel; (2) selecting from menus provided by the On-Screen Display
(OSD).
Setup is fast and easy: simply plug cables into their appropriate ports. There is
no software to configure, and no incompatible problems. It works on multiple
operating platforms (PC compatible, Sun, etc.).
There is no better way to save time and money than with a DS-12910/DS-12911
Installation: Since a single console manages all of the computers, the DS-12910/
DS-12911 setup (1) eliminates the expense of having to purchase a separate
keyboard, monitor, and mouse for each computer; (2) saves all the space those
extra components would take up; (3) saves on energy costs; (4) eliminates the
inconvenience and wasted effort involved in constantly moving from one
computer to another.
