Introduction
Overview
The CS261 is a DVI micro-processor controlled computer sharing solution that
offers a multi-user/single-tasking experience and enables two users to share the
use of a single USB computer from two separate consoles (monitor, USB
keyboard, USB mouse, speaker and microphone). The CS261 is ideal for small
office environments. All programs, files and resources on any connected
computer can be easily accessed and shared by both users without the
additional complexity and expense of setting up a network environment. Users
are able to operate computers on the installation one by one while, for
additional security, the other console's video and audio output is optionally
disabled.The CS261 even provides a convenient OSD (On Screen Display)
function that allows either of the Consoles to access any computer connected
to the system by means of an on screen, console status driven interface.
Setup is fast and easy; plugging cables into their appropriate ports is all that is
entailed. There is no software to configure, so there is no need to get involved
in complex software installation routines or be concerned with incompatibility
problems. Because the CS261 intercepts keyboard input directly, it works on
any hardware platform and with all operating systems.
Responding to the growing use of audio input/output in the workstation space,
the CS261 has been designed with built in microphone and speaker support, as
well.

Chapter 4
Operation
Overview
The CS261 features two operation modes: Auto Mode and Manual Mode. For
a brief overview of these modes, see Operation Modes, page 32.
Auto Mode
For general, low-priority scenarios, default Auto Mode offers the simplest
usability for computer sharing where control of the computer is selected on a
first come, first served basis.
Auto Mode operates according to the following rules:
1. When the CS261 is turned on it starts in Auto Mode, and operates on a
first come, first served basis. Both Console LEDs are On; the Manual LED
is Off.
2. The first user to strike the keyboard or move the mouse gains control of
the computer. As soon as this occurs:
The Console LED that corresponds to the user's console turns On.
The Console LED for the other console turns Off.
The CS261 locks onto that user's console.
If the user uses the keyboard or moves the mouse, a message appears
on the other user’s monitor indicating that the system is in use. After
10 seconds, the message will disappear and the user can view the
computer display again (if the other user stops using the keyboard and
moving the mouse). When the other user uses the keyboard or moves
the mouse again, the OSD message will reappear:
The System Is Occupied. Please Wait.
The user who has control of the computer can prevent the other user
from viewing the computer display and listening to the audio output by
entering the following Hotkey combination:
[Num Lock]+[-],[D]
If the other user uses the keyboard or moves the mouse, a message
appears indicating that the system is in use. After 10 seconds, the
message disappears and the monitor displays a black background. If the
CS261 User Manual
12
user uses the keyboard or moves the mouse, the OSD message will
reappear.
3. If the user who has access to the CS261 does not use the keyboard or move
the mouse before the Timeout Period (set with hotkeys) elapses:
The CS261 unlocks from that user's console;
Then, the CS261 switches to Auto Mode;
Both Console LEDs turn On;
The Manual LED is Off (since the CS261 is in Auto Mode);
Either console may take control of the computer.
4. To terminate Auto Mode access, repeatedly press the MANUAL/AUTO
Button until the desired console controls the device.
Private Mode (Console 1)
For high-priority scenarios, Private Mode offers the best control during
computer sharing where a specific user can at any time take control of the
system. Console 1 or Console 2 can be set as the privileged user by setting the
DIP switch pin four on or off (see page 13), which can also prevent the non-
privileged user from viewing and controlling the computer (see page 11).
Private Mode operates within Auto Mode and does not include a Timeout
Period.
To enter Private Mode:
1. Make sure that the device is in Auto Mode and that DIP switch pin 3 is set
to the On position before powering on the CS261.
2. Set Console 1 user as the privileged user if DIP switch pin 4 is set to On
position. Otherwise, Console 2 user will be the privileged user.
3. Power on the CS261.
4. Wait for the Timeout period to expire (default: 5s).
5. From the keyboard of the privileged user, press the Shift key six times
within two seconds.
In Private Mode, the user who does not have control of the computer (i.e.
not the privileged user) cannot view or hear the computer. As a result, the
OSD warning message does not appear in Private Mode.
To exit Private Mode:
From the keyboard of the privileged user, press the Shift key six times
within 2 seconds.

Or
Press the MANUAL/AUTO Button.
Screen Saver
To protect the screens, when the CS261 is in Auto Mode or Manual Mode and
no one is accessing the computer, both monitors will display a black
background. If one of the consoles accesses the computer, the black
background screen will disappear. To enable this function, set DIP switch pin
2 to the On position.

Manual Mode
For longer tasks where uninterrupted access to the computer is required,
Manual Mode offers the best operation setting for computer sharing. It is
invoked by repeatedly pressing the MANUAL/AUTO Button to bring the
focus to the desired console as follows:
Auto Mode → Manual Mode (Console 1) → Manual Mode (Console 2) →
Auto Mode
When Manual Mode is invoked, the CS261 switches to the selected
console and prohibits the other console from controlling the computer. The
selected console retains control until the MANUAL/AUTO Button is
pressed again.
A message appears on the other user’s monitor indicating that the system
is in use. After 10 seconds, the message disappears and the user can view
the computer display. If the user strikes the keyboard or moves the mouse,
the OSD message is displayed again:
The System Is Occupied. Please Wait.
The user who has control of the computer can prevent the other user from

The Firmware Upgrade Utility
Introduction
The purpose of the Windows-based Firmware Upgrade Utility is to provide an
automated process for upgrading all CS261 switches in an installation. The
program comes as part of a Firmware Upgrade Package that is specific for each
device.
As new firmware versions become available, new firmware upgrade packages
are posted on our website. Check the website regularly to find the latest
information and packages.
Downloading the Firmware Upgrade Package
To download the firmware upgrade package:
1. that is not part of your KVM installation, go to our website
(www.aten.com) and choose the model name of your device. A list of
available firmware upgrade packages will appear.
2. Choose the firmware upgrade package that you wish to install (usually the
most recent) and download it to your computer.
CS261 User Manual
22
Preparation
To prepare for the firmware upgrade, do the following:
1. Use the KVM Cable Set provided with this unit to connect a USB port on
your computer to the PC Port section of your switch.
2. Shut down all the computers on the KVM installation.
3. The CS261 now enters Firmware Upgrade Mode. The two Ports LEDs
flash together to indicate that the unit is in Firmware Upgrade Mode.
Note: While the CS261 is in Firmware Upgrade Mode, normal keyboard
and mouse functions are suspended. You must complete the
firmware upgrade or exit Firmware Upgrade Mode to regain normal
control of the console.

Starting the Upgrade
To upgrade the firmware:
1. Run the downloaded firmware upgrade package file by double-clicking
the file icon.
The Firmware Upgrade Utility welcome screen appears:
Note: The screens shown in this section are for reference only. The
wording and layout of the actual screens put up by the Firmware
Upgrade Utility may vary slightly from these examples.
2. Read and Agree to the License Agreement (enable the I Agree radio button).
3. Click Next to continue. The Firmware Upgrade Utility main screen
appears. The devices capable of being upgraded are listed in the Device
List panel:
CS261 User Manual
24
4. Select your device. Its description appears in the Device Description
panel. Click Next to perform the upgrade.
If you enabled Check Firmware Version, the Utility compares the device’s
firmware with that of the upgrade file’s. If it finds that the device’s
firmware is newer than the upgrade or equal to it, it brings up the dialog
box informing you of this and gives you the option to Continue or Cancel.
If you did not enable Check Firmware Version, the Utility installs the
upgrade files without checking whether or not they are newer.
As the upgrade proceeds, status messages appear in the Status Messages
panel, and the progress toward completion is shown on the Progress bar.

procedure was successful.
Click Finish to close the Firmware Upgrade Utility.

Safety Instructions
General
Read all of these instructions. Save them for future reference.
Follow all warnings and instructions marked on the device.
Do not place the device on any unstable surface (cart, stand, etc.). If the
device falls, serious damage will result.
Do not use the device near water.
Do not place the device near, or over, radiators or heat registers.
The device cabinet is provided with slots and openings to allow for
adequate ventilation. To ensure reliable operation, and to protect against
overheating, these openings must never be blocked or covered.
The device should never be placed on a soft surface (bed, sofa, rug, etc.) as
this will block its ventilation openings. Likewise, the device should not be
placed in a built in enclosure unless adequate ventilation has been
provided.
Never spill liquid of any kind on the device.
Unplug the device from the wall outlet before cleaning. Do not use liquid
or aerosol cleaners. Use a damp cloth for cleaning.
The device should be operated from the type of power source indicated on
the marking label. If you are not sure of the type of power available,
consult your dealer or local power company.
The device is equipped with a 3-wire grounding type plug. This is a safety
feature. If you are unable to insert the plug into the outlet, contact your
electrician to replace your obsolete outlet. Do not attempt to defeat the
purpose of the grounding-type plug. Always follow your local/national
wiring codes.
Do not allow anything to rest on the power cord or cables. Route the
power cord and cables so that they cannot be stepped on or tripped over.
If an extension cord is used with this device make sure that the total of the
ampere ratings of all products used on this cord does not exceed the
extension cord ampere rating. Make sure that the total of all products
plugged into the wall outlet does not exceed 15 amperes.

power supply.
Unplug the power cable before removing the power supply.
If the system has multiple sources of power, disconnect power from the
system by unplugging all power cables from the power supplies.
Never push objects of any kind into or through cabinet slots. They may
touch dangerous voltage points or short out parts resulting in a risk of fire
or electrical shock.
