Introduction
Overview
The CS261 / CS261TK 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 /
CS261TK 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 / CS261TK 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 / CS261TK 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 / CS261TK has been designed with built in microphone and speaker
support, as well.
CS261TK is CS261 that bundled with KVM over IP Access Control Box. The
2XRT-0015G KVM over IP Access Control Box allows users to enable or
disable remote over IP control privilege by simply pressing a control button.
It’s fast and easy to set up the 2XRT-0015G. Simply plug the 2XRT-0015G’s
cables to the CS261 / CS261TK. There is no need to install software or
configure devices - just plug and play,.
In addition, the cable length of the 2XRT-0015G reaches 5 meters, enabling
connection to the transmitter over longer distances for more flexible
installation.

Chapter 4
Operation
Overview
The CS261 / CS261TK features two operation modes: Auto Mode and Manual
Mode. For a brief overview of these modes, see Operation Modes, page 35.
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 / CS261TK 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 / CS261TK 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

DIP switch pin four on or off (see page 15), which can also prevent the nonprivileged user from viewing and controlling the computer (see page 13).
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 / CS261TK.
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 / CS261TK.
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:

The Firmware Upgrade Utility
Introduction
The purpose of the Windows-based Firmware Upgrade Utility is to provide an
automated process for upgrading all CS261 / CS261TK 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.
23
CS261 / CS261TK User Manual
Preparation
To prepare for the firmware upgrade, do the following:

your computer to the PC Port section of your switch.
2. Shut down all the computers on the KVM installation.
3. The CS261 / CS261TK 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 / CS261TK is in Firmware Upg rade 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.
