OVERVIEW
8 ports/16 ports USB/PS/2 KVM (Keyboard, Video, Mouse) Switches are control units
that allow access and control of up to 8 (DS-23200-2) or 16 (DS-23300-2) 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-23200-2/DS-23300-2
Installation: Since a single console manages all of the computers, the
DS-23200-2/DS-23300-2 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.
