Basic Operation
Manual Switching
There are three convenient methods to access the computers: Manual – which
involves pressing the port selection touc h panel located on the unit’s front
panel; Mouse port-switching, and Hotkey – which involves entering
combinations from the keyboard . Hotkey port selection and Mouse port-
switching are discussed in the next chapter.
For manual port selection:
To bring comple te focus (audio, KVM, and USB) to a computer, either:
a) press the port selection touch panel that corresponds to that computer;
or: b) press the Mode touch panel once (the Mode touch panel three icons
flash) and then press the port selection touch panel that corresponds to that
computer. All three port icons light up.
To bring only the KVM focus to a computer, press the Mode touch panel
twice (the Mode touch panel KVM ico n flashes), and th en press the port
selection touch panel that corresponds to that computer. The port’s KVM
icon lights up.
To bring only the audio focus to a computer , press the Mode touch panel
three times (the Mode touch panel audio icon flashes), and then press the
port selection touch panel that corresponds to that computer. The port’s
audio icon lights up.
To bring only the USB focus to a computer, press the Mode touch panel
four times (the Mode touch panel USB icon flashes), and then press the
port selection touch panel that corresponds to that computer. The port’s
USB icon lights up.
Note: 1. Press and release either port selection touch panel to stop Auto
Scan Mode (See Auto Scanning, page 19). The KVM focus goes
to the computer attached to the corresponding port of the touch
panel you pressed.
2. Allow the output device a few seconds to stabilize and display
video content befo re switching to another input source.
3. If a port is not selected within five seconds of pushing the Mode
touch panel, the Mode touch panel will power off.

Hot Plugging
The CS1942 / CS1944 supports USB hot plugging – components can be
removed and added back into the installation by unplugging their cables from
the USB hub ports without the need to shut the unit down.
Powering Off and Restarting
If it becomes necessary to Power Off the unit, before starting it back up you
must do the following:
1. Shut down all the comput ers that are attached to the switch.
2. Unplug the switch’s power adapter cable.
3. Wait 10 seconds, then plug th e switch’s power adapter cable back in.
4. After the switch is up, Power On the computers.
Port ID Numbering
Each KVM port on the CS1942 / CS1944 switch is assigned a port number (1
and 2 on the CS1942; 1, 2, 3, and 4 on the CS1944). The port numbers are
marked on the rear and side panels of the switch (see CS1942 / CS1944 Rear
View, page 8, 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 USB peripheral,
and audio focus with the Hotkey port selection method (see Port Switching,
page 17, for details).

Chapter 4
Keyboard Port Operation
The CS1942 / CS1944 provides an extensive, easy-to-use, hotkey function that
makes it convenient to control and configure your KVM installation from the
keyboard. Hotkeys provid e asynchronous (independent) switching of the
KVM, USB hub and audio focus. If you wish, you can give one computer the
KVM console focus, another the USB hub focus and the other(s) the audio
focus.
Port Switching
All port switches begin with tapping the Scroll Lock key twice. The tables
below describe the actions that each combination performs.
Note: If using the Scroll Lock key conflicts with other programs running on
the computer, the Ctrl key can be used, instead. See Alternate Port
Switching Keys, page 21, for details.

Auto Scanning
The CS1942 / CS1944’s Auto Scan feature automatically cycles the KVM
focus through the computer ports at regular intervals. This allows you to
monitor the computer activ ity without having to take the trouble of switch ing
from port to port manually. See the table below for details.
Note: 1. The n stands for the number of seconds that the CS1 942 / CS1944
should dwell on a port before moving on to the next. Replace the n
with a number between 1 and 99 when entering this hotkey
combination.
2. While Auto Scan Mode is in effect, ordinary keyboard and mouse
functions are suspended – only Auto Scan Mode compliant
keystrokes and mouse clicks can be input. You must exit Auto Scan
Mode in order to regain normal control of the console.
3. Although the video focus switches from port to port, the audio and
USB focus do not switch. They stay at the port they were on when
Auto Scanning started.
4. To exit Auto Scan Mode, press the Esc key, or the Spacebar.
Hotkey Action
[Scroll Lock] [Scroll

The Firmware Upgrade Utility
The Windows-based Firmware Upgrade Uti lit y (FWUpgrade.exe) provides a
smooth, automated process for upgrading the CS1942 / CS1944’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 the website regularly to find the
latest packages and information relating to them:
http://www.aten.com
Before you Begin
To prepare for the firmware upgrade, do the follo wing:
1. From a computer that is connected to your KVM installation, go to our
Internet support site and choose the model name that relates to your device
(CS1942 / CS1944) to get a list of available Fi rmware Upgrade Packages.
2. Choose the Firmware Upgrade Package you want to in stall (usually the
most recent), and download it to your computer.
3. Shut down all other computers (excep t the one used to download your
Firmware Upgrade Package) on your CS1942 / CS1944 installation.
4. Invoke Firmware Upgrade Mode (see Firmware Upgrade Mode, page 23).
The front panel LEDs flash together to in dicat e Firmware Upgrade Mode
is in effect.
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.

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.
If you enabled Check Firmware Version, the Utility compares the device’s
firmware level with that of the upgrade files. If it fin ds 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 didn’t enable Check Firmware Version, the Utility installs the
upgrade files without checking whether they are a higher level, or not.
As the Upgrade proceeds, status messages appear in the Status Messages

Troubleshooting
Overview
Operation problems can be due to a variety of causes. The first step in solving
them is to make sure that all cables are securely attached and seated completely
in their sockets.
In addition, updating the product’s firmware may solve problems that have
been discovered and resolved since the prior version was released. If your
product is not running the latest firmware version, we strongly recommend that
you upgrade. The Firmware Upgrade Utility , page 29, for upgrade details.
Symptom Possible Cause Action
Erratic behavior. Unit not receiving
enough power. Use a DC 5.3 V power adapter if you
are not already using one. If you are
already using a power adapter, check
that it matches the system
specifications, and that it is plugged in
and functioning properly.
Keyboard and/or
mouse need to be
reset.
Unplug the cable(s) from the console
port(s), then plug it/them back in.
No connection to the
computer. Check the cable from the switch to the
computer to make sure it is properly
connected.
KVM switch needs to
be reset. Power off all devices on the
installation; power off the KVM switch;
wait five seconds; then power up.
USB devices not
responding. USB ports need to be
reset. Unplug the device’s USB cable from
