Chapter 1
Introduction
Overview
The CS82U / CS84U PS/2-USB KVM Switch is a desktop control unit that
allows users to access two or four computers from a single KVM console (PS/
2 or USB keyboard and mouse, and VGA monitor). The CS82U / CS84U
comes with ATEN’s patented Video DynaSyncTM technology, which
eliminates boot-up display problems and optimizes resolution, and features
dual console keyboard and mouse ports, meaning any combination of PS/2 or
USB keyboard and mouse can be used.
There are three convenient methods to access the computers: port selection
pushbuttons located on the unit’s front panel; hotkey combinations entered
from the keyboard; and the very latest in mouse port-switching – simply
double-click on the scroll wheel of a USB mouse to change ports.
Setup is fast and easy; simply plug cables into their appropriate ports. There is
no software to configure, no installation routines, and no incompatibility
problems. Since the CS82U / CS84U intercepts keyboard input directly, it will
work on multiple computing platforms.
There is no better way to save time and money than with a CS82U / CS84U
installation. Since a single console manages all of the computers, the CS82U /
CS84U setup: eliminates the expense of having to purchase separate console
components for each computer; saves all the space those extra components
would take up; saves on energy costs; and eliminates the inconvenience and
wasted effort involved in constantly moving from one computer to another.

Mouse Port-switching
The CS82U / CS84U supports the very latest in mouse port-switching – simply
double-click the scroll wheel of your USB mouse to cycle through the ports.
Note: 1. This featured is only supported by USB 3-key scroll wheel mice.
2. The default setting is disabled
3. This feature is only supported when Mouse Emulation is enabled. See
Mouse Port-switching, page 21, for details.
Powering Off and Restarting
If it becomes necessary to power off the CS82U / CS84U unit, before starting
it back up you must do the following:
1. Shut down all the computers that are attached to the switch.
2. Unplug the switch’s power adapter cable.
3. Wait 10 seconds, then plug the switch’s power adapter cable back in.
4. After the switch is up, power on the computers.
Port ID Numbering
Each KVM port section on the CS82U / CS84U switch is assigned a port
number. (1 or 2 for the CS82U; 1 to 4 for the CS84U). The port numbers are
marked on the rear panel of the switch (see page 7 for details).
The Port ID of a computer is derived from the KVM port number it is
connected to. For example, a computer connected to KVM port 2 has a Port ID
of 2.
The Port ID is used to specify which computer gets the KVM focus with the
Hotkey port selection method (see page 15 for details).
