Introduction
Overview
The CS231 / CS231TK is a powerful, micro-processor controlled computer
sharing device. It is a multi-user, single-tasking device that enables two users
to share the use of a single USB or PS/2 computer from two separate consoles
(USB keyboard, USB mouse, and monitor).
The CS231 / CS231TK is ideal for small office and home office (SOHO)
environments. All programs, files and resources on the computer can be easily
accessed and shared by both users without the bother and expense of setting up
a costly network environment.

Operation
Overview
The CS231 / CS231TK features two operation modes: Auto Mode and Manual
Mode.
Auto Mode
Auto Mode operates according to the following rules:
1. When the CS231 / CS231TK is turned on it starts in Auto Mode, and
operates on a first-come-first-served basis. B oth 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 CS231 / CS231TK locks onto that user's console.
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 user who has control of the computer can prevent the other user
from viewing the computer display by entering the following Hotkey
combination:
[Num Lock]+[-],[D]
If the other user strikes 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
user strikes the keyboard or moves the mouse, the OSD message is
displayed again.
3. If the user who has access does not strike the keyboard or move the mouse
before the Timeout Period (set with DIP switch pins 1 and 2) elapses:
The CS231 / CS231TK unlocks from that user's console;
Then, the CS231 / CS231TK switches to Auto Mode;
Both Console LEDs turn On;
The Manual LED is Off (since the CS231 / CS231TK is in Auto Mode);
Either console may take control of the computer.
11
Chapter 4. Operation
4. To terminate Auto Mode access, repeatedly press the MANUAL/AUTO
Button until the desired console controls the device.
Timeout
In Auto Mode, the setting of DIP switch pins 1 and 2 determines the amount of
time that passes from the last input by the controlling console to when the
console lock is released. Refer to the DIP Switch Settings Table, page 13 for
the pin settings and their corresponding Timeout lengths. (See page 11 for
more information about Auto Mode.)
Note: For best results, set the DIP switch pins BEFORE turning on either the
CS231 / CS231TK or the computer.
Private Mode (Console 1)
Private Mode operates within Auto Mode. In Private Mode, the Console 1 user
can control the computer, while preventing the Console 2 user from viewing
and controlling the computer. The Timeout Period does not apply in Private
Mode.
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.
2. Wait for the Timeout period to expire.
3. From the keyboard of Console 1, press the Shift key six times within two
seconds.
After the Timeout Period expires, Console 1 will display the computer
desktop and have control of the computer. A message appears on the
monitor of Console 2 indicating that the system is in use. After 10 seconds,
the message disappears and the monitor displays a black background. If
the Console 2 user strikes the keyboard or moves the mouse, the OSD
message is displayed again.
To exit Private Mode:
1. From the keyboard of Console 1, press the Shift key six times within 2
seconds; or, press the MANUAL/AUTO Button.
Screen Saver
To protect the screen phosphors, when the CS231 / CS231TK is in Auto Mode
and no one is accessing the computer, a stripe image can scroll down the screen.
To enable this function, set DIP switch pin 4 to the On position.

invoked by repeatedly pressing the MANUAL/AUTO Button to bring the
focus to the desired console as follows:
Auto Mode > Console 1 > Console 2 > Auto Mode
When Manual Mode is invoked, the CS231 / CS231TK 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 user who has control of the computer can prevent the other user from
viewing the computer display by entering the following Hotkey
combination:

The Firmware Upgrade Utility
Introduction
The Windows-based Firmware Upgrade Utility (FWUpgrade.exe) provides a
smooth, automated process for upgrading the computer sharing device’s
firmware.
The Utility comes as part of a Firmware Upgrade Package that is specific for
each device. New firmware upgrade packages are posted on our Website as
new firmware revisions become available. Check our Website regularly to find
the latest packages and information relating to them.
Before You Begin
To prepare for the firmware upgrade, do the following:
1. From a computer that is not part of your installation, go to our Website and
choose the model name that relates to your device (CS231 / CS231TK) to
get a list of available Firmware Upgrade Packages.
2. Choose the Firmware Upgrade Package you want to install (usually the
most recent) and download it to your computer.
3. Shut down the computer(s) on your CS231 / CS231TK installation.
4. Connect the provided firmware upgrade cable to the firmware upgrade
port on the CS231 / CS231TK and to a COM port on the computer you
used to download the Firmware Upgrade Package.
5. From the console connected to the CS231 / CS231TK, invoke HSM (see
page 14). Key in the letters u-p-g-r-a-d-e, and then press [Enter]. When in
firmware upgrade mode the front panel LEDs flash in unison.
Starting the Upgrade
To upgrade your firmware:
1. Run the downloaded Firmware Upgrade Package file - either by double
clicking the file icon, or by opening a command line and entering the full
path to it.
The Firmware Upgrade Utility Welc om e screen appears:

appears:
The Utility inspects your installation. All the devices capable of being
upgraded by the package are listed in the Device List panel.
4. As you select a device in the list, its description appears in the Device
Description panel.
5. After you have made your device selection(s), Click Next to perform the
upgrade.

Chapter 5. The Firmware Upgrade Utility
If you enabled Check Firmware Version, the Utility compares the device's
firmware level with that of the upgrade files. If it finds that the device's
version is higher than the upgrade version, it brings up a dialog box
informing you of the situation 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 a higher level.
As the Upgrade proceeds, status messages appear in the Status Messages
panel, and the progress toward completion is shown on the Progress bar.
Upgrade Succeeded
After the upgrade has completed, a screen appears to inform you that the
procedure was successful:
Click Finish to close the Firmware Upgrade Utility.
After a successful completion, the switches exit Firmware Upgrade Mode.

Troubleshooting
Problem Solution
Nothing happens when I
move the mouse or
press keys on the
keyboard.
I am using two monitors
with differing screen
resolutions. Why can’t I
see the entire desktop
on the monitor with the
higher resolution?
After setting a PC
keyboard to emulate the
Apple keyboard layout, it
still is not emulating the
Mac keyboard.
1. Ensure that the KVM cable connectors are firmly
secured to the computer port on the CS231 / CS231TK
and to the keyboard and mouse ports on the computer
before connecting the power cable or turning on the
computer.
2. Press the Manual/Auto Mode Button to switch the console.
The monitor with the lowest screen resolution sets the
maximum screen resolution that can be used. Choose a
screen resolution in the computer’s graphics card that is
supported by both monitors.
Restart the computer.
