1. Introduction
Thank you for purchasing the LINDY IP KVM SWITCH CLASSIC USB. This device allows
operators to monitor and access their computers from remote locations. The IP KVM SWITCH
CLASSIC USB connects to the internet, intranet, LAN or WAN using standard CAT5 or higher
cable, then uses a KVM cable to connect a local KVM switch or server.
The IP KVM SWITCH CLASSIC USB combines convenient digital remote KVM access and
control with integrated system management. It captures, digitizes and compresses the video
signal and transmits it alongside the keyboard and mouse signals, to and from a remote
computer. The IP KVM SWITCH CLASSIC USB provides a non-intrusive solution for remote
access and control. Remote access and control software runs on its embedded processors only
– so there is no interference with server operation, or impact on network performance.
The IP KVM SWITCH CLASSIC USB supports PS/2 as well as USB keyboard/mouse and 15way VGA type monitor connections. It automatically detects the video mode of the console and
allows manual fine tuning for improved video quality. However please note that when using a
USB mouse and keyboard from the local console you have to use the USB connection to the
server/KVM switch too. And when using PS/2 keyboard and mouse also the PS/2 connection to
the server/KVM Switch has to be used.
The IP KVM SWITCH CLASSIC USB also features remote mass storage support – the unit
connects via a USB connection to the server/KVM switch and allows virtual storage devices
located at the remote users computer to provide data and a virtual drive to the server.

2.2 Connections
You may either use PS/2 or USB mouse and keyboard.
However, please note that USB mouse and keyboard signals from your local console will not be
converted and output as PS/2 signals to your server/KVM switch!
2.2.1 Host or KVM Switch Connection Side
Use the 3in1 KVM cable (VGA & 2x PS/2) attached to the KVM Switch to make the connections
to the host computer. If you either want to use the USB mouse and keyboard or the USB virtual
media feature, use the supplied USB A-Mini B cable to connect the USB Mini B port on the back
of the IP KVM SWITCH CLASSIC USB to a USB port on your server or KVM switch.
2.2.2 Console Connection Side
Connect your local keyboard, monitor and mouse console using the short VGA and PS/2 3in1
KVM splitter cable - connected to the IP KVM Switch port labelled Local - if you want to use
PS/2 peripherals – if you want to use USB peripherals only you may connect your monitor
directly to the HD15 connector on the IP KVM Switch. If you want to use a USB mouse and
keyboard connect them to the ports labelled USB located below the RJ45 ports. However,
please note that USB mouse and keyboard signals from your local console will not be converted
and output as PS/2 signals to your server/KVM switch.
2.2.3 Network Connection
The IP KVM SWITCH CLASSIC USB provides two RJ45 ports for Ethernet connection. The
ports can be used with a 100Mbps, 100Base-TX connection or a 10Mbps, 10Base-T
connection. The IP KVM SWITCH CLASSIC USB will sense the connection speed and
automatically adjust to the appropriate operation mode. The second port can be used to
cascade multiple KVM IP Switches.
10Mbps Connection, 10Base-T
Please note that this slow connection may not provide sufficient performance for the
compressed video data traffic and will result in low video and colour resolution and significantly
delayed reaction time for remote connections.

3. Configuration
The IP KVM SWITCH CLASSIC USB’s
communication interfaces are all based on
TCP/IP. The switch comes pre-configured
with the IP configuration detailed here:
If this initial configuration does not meet your requirements, the following section describes the
configuration that is necessary to access the IP ACCESS SWITCH CLASSIC USB for the first
time.
3.1 Initial IP Configuration via Network
If DHCP mode is enabled (IP auto configuration = DHCP), the IP Access KVM Switch Classic
will try to contact a DHCP server in the subnet to which it is physically connected. If a DHCP
server is found, it may provide a valid IP address, gateway address and net mask. Before you
connect the device to your local subnet, be sure to complete the corresponding configuration of
your DHCP server. It is recommended to configure a fixed IP assignment to the MAC address of
the IP Access KVM Switch Classic. You can find the MAC address labelled on the bottom side
of the metal housing.
There is a Network Setup Software tool (PSetup) for setting up the network configuration (IP
address, Subnet mask, DHCP, etc). It is useful when you want to change the network settings
or when you cannot access to the unit due to not knowing the network settings of the unit. In
this case, you can view or change the settings via this utility. Follow the procedure described on
the next page (Section 3.3.)
IP auto configuration none
IP-Address 192.168.0.70
Net-mask 255.255.255.0
Default-Gateway none
3.2 Initial Configuration via Serial Console
The IP KVM SWITCH CLASSIC USB has a serial
line interface (host side) for connecting a serial
terminal. This connector is compliant with the RS232 serial line standard. The serial line has to be
configured with the parameters given in this table:
When configuring with a serial terminal, reset the IP KVM SWITCH CLASSIC USB and
immediately press the ESC key. You will see some device information and a “=>” prompt. Type
config and press the Enter key. Wait a few seconds for the configuration questions to appear.
As you proceed, the following questions will appear on the screen. To accept the default values
(shown in square brackets below) press the Enter key.
IP auto configuration (non/dhcp/bootp) [dhcp]:
IP [192.168.0.70]:
Net mask [255.255.255.0]:
Gateway (0.0.0.0 for none) [0.0.0.0]:
Bits/second 115200
Data bits 8
Parity No
Stop bits 1
Flow Control None

3.3 IP KVM SWITCH CLASSIC USB Setup Tool
3.3.1 MAC Address Detection
Connect the IP KVM SWITCH CLASSIC USB to your computer either via a local network, or via
USB. If you use a USB connection Windows will detect the IP KVM SWITCH CLASSIC USB as
a ‘Removable Disk’ and an appropriate drive letter will be assigned.
Start the setup tool from the CD ROM.
A window opens as shown below:
On the upper left corner, the MAC address of the IP KVM SWITCH CLASSIC USB is displayed.
To detect the MAC address, press the Refresh Devices button. The displayed MAC address is
the same as that printed on the sticker on the base of the unit.
On the lower right corner of the window, there are two buttons: Query Device and Setup
Device. Press the Query Device button to display the preconfigured values of the network
configuration. The values are displayed in the text fields located above. If necessary, adjust the
network settings to your needs. To save the changes enter a user login and a password (see
3.3.2 Authentication, on page 9) and then press the Setup Device button.
6
3.3.2 Authentication
To adjust the authentication settings, enter your login as a super user and change your
password.
Super user login
Enter the login name of the super user. The initial value is super. All of the characters are lower
case.
Super user password
Enter the current password for the super user. This initial value is pass. All of the characters are
lower case. Please change the password when configuring the IP KVM Switch for the first time.
Not to change the default password may cause some unauthorized access to the switch and the
servers connected! Please make sure to store the new password in a secure place you easily
can find once you forget it.
New super user password
Enter the new password for the super user.
New password (confirm)
Re-type the new password for the super user.
To close the window and accept the changes, press the OK button, otherwise press the Cancel
button.
3.3.3 IP Auto Configuration
With this option, you can specify whether the IP KVM SWITCH CLASSIC USB should obtain its
network settings from a DHCP or BOOTP server. From the drop down list select either DHCP or
BOOTP. If you select NONE, the IP auto configuration is disabled and you should manually
input the following network settings:
IP address
The IP address the IP KVM SWITCH CLASSIC USB uses.
Net mask
The net mask of the connected IP subnet.
Gateway address
The IP address of the default router for the connected IP subnet. If you do not have a default
router, enter 0.0.0.0.
7
3.4 Keyboard, Mouse and Video configuration
Between the IP KVM SWITCH CLASSIC USB and the host, there are two interfaces available
for transmitting keyboard and mouse data: USB and PS/2. The correct operation of the remote
mouse depends on several settings which will be discussed in the following subsections.
3.4.1 IP KVM SWITCH CLASSIC USB Keyboard Settings
The IP KVM SWITCH CLASSIC USB settings for the host's keyboard type have to be correct in
order to make the remote keyboard work properly. The settings can be checked using the IP
KVM SWITCH CLASSIC USB web front-end.
3.4.2 Remote Mouse Settings
A common problem with KVM devices is the synchronization between the local and remote
mouse cursors. The IP KVM SWITCH CLASSIC USB addresses this problem with an intelligent
synchronization algorithm. There are two mouse modes available on the IP KVM SWITCH
CLASSIC USB: Auto mouse speed and Fixed mouse speed.
Auto mouse speed
The automatic mouse speed mode tries to detect the speed and acceleration settings of the
host system automatically. Speed detection is performed during mouse synchronization. If the
mouse does not move correctly, there are two ways to re-synchronize the local and remote
mouse:
Fast Sync: Fast synchronization is used to correct a temporary, but fixed skew. Choose this
option using the Remote Console options menu or by pressing the mouse synchronization
hotkey sequence - [ALT] + [F12]
Intelligent Sync: If the fast sync does not work correctly or the mouse settings have been
changed on the host system, you can use the intelligent resynchronization option. This method
can be accessed from the Mouse Handling sub menu of the Remote Console Option menu.
Intelligent synchronization requires a correctly adjusted picture. Use the auto adjustment
function or manual correction in the Video Settings panel to setup the picture. The Sync mouse
button on top of the Remote Console can behave differently, depending on the current
state of mouse synchronization. Usually pressing this button leads to a fast sync, except in
situations where the KVM port or the video mode was recently changed.
Tip: When first started, if the local mouse pointer is not synchronized with the remote mouse
pointer, click the Auto Adjust Button once. If the mouse is still not synchronized select
Intelligent Sync from the Mouse Handling sub menu of the Remote Console Option menu.
Fixed mouse speed
This mode just translates the mouse movements from the Remote Console in a way that one
pixel move will lead to ‘n’ pixel moves on the remote system. This parameter ‘n’ is adjustable.
However, it should be noted that this works only when mouse acceleration is turned off on the
remote system.
8
3.4.3 Host System Mouse Settings
The host's operating system obtains various settings from the mouse driver.
Note: The following limitations do not apply when using USB mice and
Windows 2000 and higher!
Special Mouse Driver
There are mouse drivers which influence the synchronization process and lead to
desynchronized mouse pointers. If this happens, make sure you do not use a special vendorspecific mouse driver on your host system.
Windows XP Mouse Settings
If using Windows XP, disable the enhance pointer precision / improve mouse acceleration
setting.
Active Desktop
If the Active Desktop feature of Microsoft Windows is enabled, do not use a plain background.
Instead, use some kind of wallpaper. Alternatively, you could also disable the Active Desktop
completely.
Navigate your mouse pointer into the upper left corner of the applet screen and move it back
and forth slightly. In this way the mouse will be resynchronized. If re-synchronizing fails, disable
mouse acceleration and repeat the procedure.
3.4.4 Single and Double Mouse Mode
The information above applies to Double Mouse Mode, where both remote and local mouse
pointers are visible and need to be synchronized. The IP KVM SWITCH CLASSIC USB also
features another mode - Single Mouse Mode, where only the remote mouse pointer is visible.
Activate this mode in the open Remote Console and click into the window area. The local
mouse pointer will be hidden and the remote one can be controlled directly. To leave this mode,
use the hotkey combination [ALT] + [F12] to free the captured local mouse pointer.
3.4.5 Recommended Mouse Settings
For the different operating systems we can give the following advice...
MS Windows 2000/2003 (Professional and Server), XP
In general, we recommend the use of a USB mouse. Choose USB without Mouse Sync. For a
PS/2 mouse choose Auto Mouse Speed. For XP disable the option called enhance pointer
precision in the Control Panel.
SUN Solaris
Adjust the mouse settings either via xset m 1 or use the CDE Control Panel to set the mouse to
1:1, no acceleration. As an alternative you may also use the Single Mouse Mode.
MAC OS X
We recommend using the Single Mouse Mode.
3.4.6 Video Modes
The IP KVM SWITCH CLASSIC USB switch recognizes a limited number of common video
modes. When running X11 on the host system, please do not use any custom mode lines with
special video modes. If you do, the IP KVM SWITCH CLASSIC USB switch may not be able to
detect them. We recommend using any of the standard VESA video modes instead.

4. Usage
4.1 Prerequisites
The IP KVM SWITCH CLASSIC USB features an embedded operating system offering a variety
of standardized interfaces. This section will describe these interfaces, and the way to use them
in a more detailed manner. The interfaces are accessed using the TCP/IP protocol family.
The following interfaces are supported:
Telnet
A standard Telnet client can be used to access an arbitrary device connected to the IP KVM
SWITCH CLASSIC USB’s serial port via a terminal.
HTTP/HTTPS
Full access is provided by the embedded web server. The IP KVM SWITCH CLASSIC USB
switch environment can be entirely managed using a standard web browser. You can access
the IP KVM SWITCH CLASSIC USB using the insecure HTTP protocol, or using the encrypted
HTTPS protocol. Whenever possible, use HTTPS.
The primary interface of the IP KVM SWITCH CLASSIC USB is the HTTP interface. This is
covered extensively in this section. Other interfaces are addressed in the relevant subsections.
In order to use the Remote Console window of your managed host system, the browser must
feature Java Runtime Environment version 1.1 or higher support. If the browser has no Java
support (such as on a small handheld device), you can still maintain your remote host system
using the administration forms displayed by the browser itself.
For a non-secure connection to the IP KVM SWITCH CLASSIC USB, we recommend the
following browsers:
Microsoft Internet Explorer version 6.0 or higher
Netscape Navigator 7.0 or Mozilla 1.6 or higher
In order to access the remote host system using a securely encrypted connection, you need a
browser that supports the HTTPS protocol. Strong security is only assured by using a key
length of 128 Bit. Some older browsers do not have a strong 128 Bit encryption algorithm.
Important: We recommend you install the latest version of Sun’s
Java Virtual Machine which can be downloaded from the
following web site:
www.java.com

Login name
super
(factory default)
Password
pass (factory default)
4.2 Logging In
4.2.1 Login to the IP KVM SWITCH CLASSIC USB
Launch your web browser. Direct it to the address of your IP KVM SWITCH CLASSIC USB
which you configured during the installation process. The address used might be a plain IP
address or a host and domain name if you have given your IP KVM SWITCH CLASSIC USB
switch a symbolic name in the DNS.
Example: Type the following in the address line of your browser when establishing an
unsecured connection:
http://<IP address of IP KVM SWITCH CLASSIC USB >
When using a secure connection, type in:
https://<IP address of IP KVM SWITCH CLASSIC USB >
This will lead you to the IP KVM SWITCH CLASSIC USB login page as shown below:
The IP KVM SWITCH CLASSIC USB has a built-in super user account that has all the
permissions enabled to administrate your IP KVM SWITCH CLASSIC USB switch:
Please note: Your web browser has to accept cookies, or else login is not possible.
Note: The user “super” is not allowed to login via the serial interface of the IP-KVM switch.
Please make sure you change the super user password immediately after you have installed
and accessed your IP KVM SWITCH CLASSIC USB for the first time. Not changing the
password for the super user is a severe security risk and could result in unauthorized access to
the switch and to the host system(s) to which it is connected.
11
4.3 Navigation
Once logged into the IP KVM SWITCH CLASSIC USB successfully, the main page appears.
This page consists of three parts; each of them contains specific information. The buttons in the
upper area allow you to navigate within the front end. The lower left area contains a navigation
bar and allows you to switch between the different sections of the IP KVM SWITCH CLASSIC
USB. Within the main area, task-specific information is displayed.
Return to the main page of the IP KVM SWITCH CLASSIC USB
Logout from the IP KVM SWITCH CLASSIC USB
This link logs out the current user and presents a new login screen. Please note that an
automatic logout will be performed if there is no activity for half an hour. Clicking one of the links
will bring you back to the login screen.
Access the Remote Console
The Remote Console is the redirected screen, keyboard and mouse of the remote host system
that the IP KVM SWITCH CLASSIC USB controls. Selecting this button opens the Remote
Console Main Window.
12
The Remote Console window is a Java Applet that establishes its own TCP connection to the IP
KVM SWITCH CLASSIC USB. The protocol that runs over this connection is neither HTTP nor
HTTPS, but RFB (Remote Frame Buffer Protocol). RFB needs to establish a connection to port
number 443. Your local network environment has to allow this connection to be made, i.e. your
firewall and, if you have a private internal network, your NAT (Network Address Translation)
settings have to be configured accordingly.
If the IP KVM SWITCH CLASSIC USB is connected to your local network environment and your
connection to the Internet is available using a proxy server only, without NAT being configured,
the Remote Console is very unlikely to be able to establish a connection. This is because
today's web proxies are not capable of relaying the RFB protocol.
If you experience problems, please consult your network administrator in order to provide an
appropriate network environment.
4.3.1 Remote Console Main Window
Starting the Remote Console opens an additional window. It displays the screen content of your
host system. The Remote Console will behave in exactly the same way as if you were sitting
directly in front of the screen of your host system. This means that the keyboard and mouse can
be used in the usual way. However, be aware of the fact that the host system will react to
keyboard and mouse actions with a slight delay. The delay depends on the bandwidth of the
line which you use to connect to the IP KVM SWITCH CLASSIC USB.
Note: Your local keyboard changes its keyboard layout according to the remote host system. If
you use a German administration system and your host system uses a US English keyboard
layout for instance, some special keys on the German keyboard will not work as expected.
Instead, the keys will result in their US English counterpart. You can circumvent such problems
by adjusting the keyboard of your remote system to the same mapping as your local one.
The Remote Console window always tries to show the remote screen with its optimal size. That
means it will adapt its size to the size of the remote screen initially and after the screen
resolution of the remote screen has been changed. However, you can always resize the
Remote Console window in your local window system as usual.

ALT] + [F12]
4.3.2 Remote Console Control Bar
The upper part of the Remote Console window contains a control bar. Using its elements you
can see the state of the Remote Console and influence the local Remote Console settings. A
description for each control follows.
Ctrl+Alt+Delete
Sends the ‘Control Alt Delete’ key combination to the remote system
Auto Adjust button
If the video display is poor quality or distorted in some way, click this button and wait a few
seconds while the IP KVM SWITCH CLASSIC USB tries to adjust itself for the best possible
video quality.
Sync mouse
Activates the mouse synchronization process. Choose this option in order to synchronize the
local AND remote mouse cursors. This is especially necessary when using accelerated mouse
settings on the host system. In general, there is no need to change mouse settings on the host.
Single/Double mouse mode
Switches between the Single Mouse Mode (where only the remote mouse pointer is visible) and
the Double Mouse Mode (where remote and local mouse pointers are visible) Single mouse
mode is only available if using SUN JVM 1.3 or higher.
Tip: When in single mouse mode use the hotkey combination [
mouse control and access the menus etc.
to release
14
Options
Opens the Options menu. A short description of each of the options
follows:
Monitor Only
Toggles the ‘Monitor Only’ filter on or off. If the filter is switched on,
no remote console interaction is possible but monitoring is.
Exclusive Access
If a user has the appropriate permission, he can force the Remote
Consoles of all other users to close. No one can open the Remote
Console at the same time again until this user disables the exclusive
access, or logs off.
A change in the access mode is also visible in the status
line indicated by this icon.
Scaling
Allows you to scale down the Remote Console window: 25% / 50% / 100% / Scale to fit. You
can still use both mouse and keyboard; however the scaling algorithm will not preserve all
display details.
Mouse Handling
The submenu for mouse handling offers two options for synchronizing the local and the remote
mouse pointer.
Fast Sync
The fast synchronization is used to correct a temporary, but fixed skew.
Intelligent Sync
Use this option if the fast sync does not work or the mouse settings have
been changed on the host system.
Note: This method takes more time than fast sync and requires a correctly
adjusted picture. Use the auto adjustment function or the manual correction in
the Video Settings panel to setup the picture.
Local Cursor
Offers a list of different cursor shapes to choose from for the local mouse pointer: Transparent,
Default, Big, Pixel, Crosshair. The selected shape will be saved for the current user and
activated the next time this user opens the Remote Console. The number of available shapes
depends on the Java Virtual Machine; a version of 1.2 or higher offers the full list.
Video Settings
Opens a panel for changing the IP KVM SWITCH CLASSIC USB video settings. The IP KVM
SWITCH CLASSIC USB features two different dialogs, which influence the video settings:
Video Settings through the HTML-Frontend: To enable the local video port, select this option.
This option decides if the local video output of the IP KVM SWITCH CLASSIC USB is active
and passing through the incoming signal from the host system.
The Noise Filter option defines how the IP KVM SWITCH CLASSIC USB reacts to small
changes in the video input signal. A large filter setting needs less network traffic and leads to a
faster video display, but small changes in some display regions may not be recognized
15
immediately. A small filter displays all changes instantly but may lead to a constant amount of
network traffic even if display content is not really changing (depending on the quality of the
video input signal). All in all the default setting should be suitable for most situations.
Video Settings through the remote console:
Brightness
Controls the brightness of the picture
Contrast
Controls the contrast of the picture
Clock
Defines the horizontal frequency for a video line and depends on the video mode. Different
video card types may require different values here. The default settings in conjunction with the
auto adjustment procedure should be adequate for most common configurations. If the picture
quality is still bad after auto adjustment you may change this setting together with the sampling
phase to achieve a better quality.
Phase
Defines the phase for video sampling, used to control the display quality together with the
setting for sampling clock.
Horizontal Offset
Use the left and right buttons to move the picture in a horizontal direction
Vertical Offset
Use the left and right buttons to move the picture in a vertical direction

Soft Keyboard
Opens up the sub-menu for the Soft-Keyboard:
Show
Pops up the Soft-Keyboard. The Soft-Keyboard is necessary in case your host system runs a
completely different language and country mapping than your administration machine.
Mapping
Used for choosing the language and country mapping of the Soft-Keyboard.
Local Keyboard
Used to change the language mapping of your browser running the Remote Console Applet.
Normally, the applet determines the correct value automatically. However, depending on your
particular KVM and your browser settings this is not always possible. A typical example is a
German localized system that uses a US-English keyboard mapping. In this case you must
manually change the local keyboard setting to the correct language.
Hotkeys
Opens a list of previously defined hotkeys. Choose
one entry; the command will be sent to the host
system.
A confirmation dialog can be added that will be
displayed before sending the selected command to
the remote host. Select OK to perform the command
on the remote host.
Encoding
These options are used to adjust the encoding level in terms of compression and colour depth.
They are only available if "Transmission Encoding" is determined automatically (see the Section
called Transmission Encoding in Chapter 5.4).
Compression Level:
You may select a value between 1 and 9 with level 1 enabling the fastest compression and level
9 the best compression. The most suitable compression level should always be seen as a
compromise between the network bandwidth that is available, on your video picture to be
transferred, and on the number of changes between two single video pictures. We recommend
17
that you use a higher compression level if the
network bandwidth is low. The higher the
compression level the more time is needed to pack
and unpack the video data on either side of the
connection. The compression quality depends on
the video picture itself, e.g. the number of the
colours or the diversity of pixels. The lower the
compression quality, the more data have to be sent
and the longer it may take to transfer the whole
video picture.
If level 0 is chosen the video compression is disabled, completely.
The option "Video Optimized" has its advantages if transferring
high-quality motion pictures. In this case the video compression is
disabled, completely and all video data is transferred via network
as full-quality video snippets. Therefore, a high amount of
bandwidth is required to ensure the quality of the video picture.
The next two options allow you to set the compression level to a
predefined level OR to set a level for "lossy" compression. This
compresses well, but leads to degradation in image quality.
Colour Depth:
Set the desired colour depth. You may select between 8 or 16 bit for Video
Optimized/compression level 0, or between 1 and 8 bit for compression
levels 1 to 9. The higher the colour depth, the more video information has to
be captured and to be transferred.
Note: If displaying motion pictures on a connection with low speed you may achieve an
improvement regarding the video transfer rate by lowering the colour depth and disabling the
option "Video Optimized". As a general result, the data rate is reduced (less bits per colour).
Furthermore, the OPMA module will not have to do any video compression. In total, this will
lead to less transfer time of the motion picture.
4.3.3 Remote Console Status Line
Status line
Shows both console and the connection state. The size of the remote screen is displayed. The
example below was taken from a Remote Console with a resolution of 1024 x 768 pixels. The
value in brackets describes the connection to the Remote Console. Norm means a standard
connection without encryption, SSL indicates a secure connection.
Furthermore, both the incoming (In:) and the outgoing (Out:) network
traffic are visible (in kb/s). If compressed encoding is enabled, a value in
brackets displays the compressed transfer rate.
For more information about Monitor Only and Exclusive Access settings, see the relevant
sections.

5. Menu Options
5.1 Remote Control
5.1.1 KVM Console
To open the KVM console, click either the menu entry on the left or on the console picture on
the right. To refresh the picture, click on the Refresh button.
For the Remote Power settings see Section 2.2.5 on page 6.
5.1.2 Telnet Console
19
The IP KVM SWITCH CLASSIC USB firmware features a Telnet server that enables a user to
connect via a standard Telnet client. If the Telnet program is using a VT 100, VT 102 or VT 220
terminal or appropriate emulation, it is even possible to perform a console redirection, as long
as the IP KVM SWITCH CLASSIC USB host is using a text mode screen resolution.
Connecting to the IP KVM SWITCH CLASSIC USB is done as usual and as required by the
Telnet client, for instance in a UNIX shell:
telnet 192.168.1.22
Replace the IP address by the one that is actually assigned to the IP KVM SWITCH CLASSIC
USB . This will prompt for the username and password in order to log into the device. The
credentials that need to be entered for authentication are identical to those of the web interface.
That means the user management of the Telnet interface is entirely controlled with the
appropriate functions of the web interface.
Once you have successfully logged into the IP KVM SWITCH CLASSIC USB a command line
will be presented and you can enter management commands.
In general, the Telnet interface supports two operation modes: the command line mode and the
terminal mode. The command line mode is used to control or display some parameters. In
terminal mode the pass-through access to serial port 1 is activated (if the serial settings were
made accordingly). All inputs are redirected to the device on serial port 1 and its answers are
displayed on the Telnet interface.
The following list shows the command mode syntax and their usage.
Help
Displays the list of possible commands
Cls
Clears the screen
Quit
Exits the current session and disconnects from the client
Version

5.2 Virtual Media
5.2.1 Floppy Disk
Follow the steps below to upload a virtual floppy image to the IP KVM SWITCH CLASSIC USB
and create a virtual floppy drive on the host system
Create a Floppy Image
First, on your client PC you must create an image of your floppy disk which can be uploaded to
the IP KVM SWITCH CLASSIC USB ’s built in memory.
UNIX and UNIX-like OS
To create an image file, make use of dd. This is one of the original UNIX utilities and is included
in every UNIX-like OS (UNIX, Sun Solaris, and Linux).
To create a floppy image file copy the contents of a floppy to a file. You can use the following
command:
dd [ if=/dev/fd0 ] [ of=/tmp/floppy.image ]
dd reads the entire disc from the device /dev/fd0 and saves the output in the specified output
file /tmp/floppy.image. Adjust both parameters exactly to your needs (input device etc.)
21
Windows
Windows users should use the tool RawWrite for
Windows which is included on the supplied CD.
Launch RawWrite, you will see the window
opposite:
Insert your floppy disk into your floppy drive. Click
the Read tab and then click on
Select a name and destination for the floppy image
file and click the Read button. As the image is
written, you will see the progress as a percentage
figure in the bottom left hand corner.
When the image has been written you can upload it
to the IP KVM SWITCH CLASSIC USB .
Uploading a Floppy Image
Click the Browse button and navigate to
the location of the image file, then click
the Upload button.
After the image has uploaded you will see the dialog below:
Click Reactivate. A virtual floppy drive will be installed on the host system and the image will be
downloaded to the virtual floppy drive from the IP KVM SWITCH CLASSIC USB . You can
access the virtual floppy drive in the same way you would a regular drive.
You can download the image from the IP KVM SWITCH CLASSIC USB to your remote system
by clicking the Download button.
Clicking Discard removes the virtual floppy image from the IP KVM SWITCH CLASSIC USB
and from the hosts system.
22
5.2.2 Create a CD-ROM/ISO Image
Follow the procedure below to create a CD-ROM image which can be accessed by the host
system via the IP KVM SWITCH CLASSIC USB .
First, on your client PC you must create an image of your CD which can be accessed by the
host system.
UNIX and UNIX-like OS
To create an image file, make use of dd. This is one of the original UNIX utilities and is included
in every UNIX-like OS (UNIX, Sun Solaris, and Linux).
To create a CDROM image file, copy the contents of the CD-ROM to a file. You can use the
following command:
dd [ if=/dev/cdrom ] [ of=/tmp/cdrom.image ]
dd reads the entire disc from the device /dev/cdrom, and saves the output in the specified
output file /tmp/cdrom.image. Adjust both parameters exactly to your needs (input device etc.).
23
Windows
To create the image file, use your favourite CD
imaging tool. Copy the whole contents of the disc
into one single image file on your hard disk.
For example, with ‘Nero’ you choose ‘Copy and
Backup’. Then, navigate to the ‘Copy Disc’
section. Select the CD ROM or DVD drive you
would like to create an image from. Specify the
filename of the image, and save the CD ROM
content in that file.
Example:
1. Create a CD image and name it image.iso
2. Create a folder on your client PC and name it
Test. Copy the file image.iso to the folder
Test.
3. Now you need to ‘share’ this folder. Right click
on the folder and select the option Sharing
and Security. Select Share this folder and
ensure the Share Name is set to Test. Click
Permissions to set permissions for users who
access this folder, according to your
requirements. Click Apply then OK to
complete.
4. Next you need to mount the image via a
Windows Share. In the IP KVM SWITCH
CLASSIC USB menu on the left hand side of
the browser select Virtual Media and from the
sub menu select CD-ROM Image.
5. Input the following parameters:
Share host: Enter the IP address of your Console PC here (e.g. 192.168.2.103)
Share name: Test (The share name of the previously created folder)
Path to image: image.iso (the name of the CD image)
User: super (Your user name, the default is super)
Password: pass (Your password, the default is pass)
6. Click Set
24
7. You will see the dialog below detailing the active image:
8. Click Reactivate. Access the console window and you will see that another CD drive has
been installed on the host computer. This is the virtual drive you have just set up. You can
access the uploaded CD image as though it were a regular CD. Click Unset to remove the
image.
SAMBA
If you would like to access the share via SAMBA, SAMBA must be set up properly. You may
either edit the SAMBA configuration file /etc/samba/smb.conf, or use the Samba Web
Administration Tool (SWAT) or WebMin to set the correct parameters.
25
5.2.3 Drive Redirection
The Drive Redirection feature allows the host system to access the CD-Rom drives, hard drives,
floppy drives etc. on your client PC.
With Drive Redirection you do not have to use an image file but may work with a drive from your
local computer on the remote machine. The drive is hereby shared over a TCP network
connection. Devices such as floppy drives, hard discs, CD ROMs and other removable devices
like USB sticks can be redirected. It is even possible to enable a write support so that for the
remote machine it is possible to write data to your local disc.
Please note that Drive Redirection works on a level which is far below the operating system.
That means that neither the local nor the remote operating system is aware that the drive is
currently redirected. This may lead to inconsistent data as soon as one of the operating systems
(either from the local machine, or from the remote host) is writing data on the device. If write
support is enabled the remote computer might damage the data and the file system on the
redirected device. On the other hand, if the local operating system writes data to the redirected
device the drive cache of the operating system of the remote host might contain older data. This
may confuse the remote host’s operating system. Therefore, we recommend to use the Drive
Redirection with care, especially the write support.
Disable Drive Redirection
If enabled the Drive Redirection is switched off.
Force read-only connections
If enabled the Write Support for the Drive Redirection is switched off. It is not possible to
write on a redirected device.
Click Apply to submit your changes.
26
The method of Drive Redirection:
Built-in Java Drive Redirection function in Remote Console
1. Run Remote Control > KVM Console.
2. Click “Floppy” icon
27
IMPORTANT
3. Click Connect Drive or Connect ISO
4. Select a drive to redirect (if Connect Drive)
5. Select a ISO image to redirect (if Connect ISO)
1. Drive Redirection is only possible with Windows 2000 and later versions.
2. Drive Redirection works on a low SCSI level. The SCSI protocol cannot recognize
partitions; therefore the whole drive selected will be shared instead of any
particular partition.
3. When connecting to a legacy KVM switch, please select PS/2 mouse from the
Keyboard/Mouse setting on the web page. Otherwise you will not be able to
use Hot-keys.
5.2.4 Options
This option allows you to disable the mass storage emulation (and hide the virtual drive) if no
image file is currently loaded. To set this option, press the button Apply.

5.3 User Management
5.3.1 Change Password
To change your password, enter the new password in the upper entry field. Retype the
password in the lower field. Click Apply to submit your changes.
5.3.2 Users And Groups
The IP KVM SWITCH CLASSIC USB comes with 2 pre-configured user accounts that have
fixed permissions. The super account has all possible rights to configure the device and to use
all functions. The user account has only the permission to open and use the Remote Console.
The default password for both accounts is pass. Ensure you change the passwords as soon as
you have installed and accessed the IP KVM SWITCH CLASSIC USB for the first time.
29
While the user account never sees the following options, the super account can change the
name and password for both accounts.
Existing users
Select an existing user for modification. Once a user has been selected, click the lookup button
to see the user information.
New User name
The new user name for the selected account.
Password
The password for the login name. It must be at least four characters long.
Confirm password
Confirmation of the above password.
30
5.4 KVM Settings
5.4.1 User Console
The following settings are user specific. This means the super user can customize these
settings for individual users separately. Changing the settings for one user does not affect the
settings for the other users.
User select box
This box displays the user ID for which the values are shown and for which the changes will
take effect. You may change the settings of other users if you have the necessary access rights.
Transmission Encoding
The Transmission Encoding setting allows you to change the image-encoding algorithm that is
used to transmit the video data to the Remote Console window. It is possible to optimize the
speed of the remote screen depending on the number of users working at the same time and
the bandwidth of the connection line (Modem, ISDN, DSL, LAN, etc.).
Automatic detection
The encoding and the compression level are determined automatically from the available
bandwidth and the current content of the video image.
Pre-configured
The pre-configured settings deliver the best result because of optimized adjustment of
compression and colour depth for the indicated network speed.
Manually
Allows adjustment of both compression rate and colour depth individually. Depending on the
selected compression rate the data stream between the IP KVM SWITCH CLASSIC USB and
the Remote Console will be compressed in order to save bandwidth. Since high compression
31
rates are very time consuming, they should not be used when several users are accessing the
IP KVM SWITCH CLASSIC USB simultaneously.
The standard colour depth is 16 bit (65536 colours). The other colour depths are intended for
slower network connections in order to allow a faster transmission of data. Therefore
compression level 0 (no compression) uses only 16 bit colour depth. At lower bandwidths only 4
bit (16 colours) and 2 bit (4 grey scales) are recommended for typical desktop interfaces. Photolike pictures have best results with 4 bit (16 grey scales). 1 Bit colour depth (black/white) should
only be used for extremely slow network connections.
Remote Console Type
Specifies, which Remote Console Viewer to use.
Default Java-VM
Uses the default Java Virtual Machine of your Browser. This may be the Microsoft JVM for
Internet Explorer or the Sun JVM if it is configured this way. Use of the Sun JVM may also be
forced (see below).
Sun Microsystems Java Browser Plug-in
Instructs the web browser of your administration system to use Sun’s JVM. The JVM in the
browser is used to run the code for the Remote Console window which is actually a Java
Applet. If you check this box for the first time on your administration system and the appropriate
Java plug-in is not already installed on your system, it will be downloaded and installed
automatically. However, in order to make the installation possible, you still need to answer the
according dialogs with yes. The download size is around 11MB. The advantage of downloading
Sun's JVM is in providing a stable and identical Java Virtual Machine across different platforms.
The Remote Console software is optimized for Sun JVM versions and offers wider range of
functionality when run with JVM.
32
Miscellaneous Remote Console Settings
Start in Monitor Mode Sets the initial value for the monitor mode. By default the
monitor mode is off. In case you switch it on, the Remote Console window will be
started in a read only mode.
Start in Exclusive Access Mode Enables the exclusive access mode
immediately at Remote Console start-up. This forces the Remote Consoles of all
other users to close. No one can open the Remote Console at the same time
again until this user disables the exclusive access or logs off.
Mouse hotkey
Allows the user to specify a hotkey combination which starts either the mouse synchronization
process if pressed in the Remote Console or is used to leave the single mouse mode.
Remote Console Button Keys
This allows simulating keystrokes on the remote system that cannot be generated locally. The
reason for this might be a missing key or the fact that the local operating system of the Remote
Console is unconditionally catching this keystroke already. Typical examples are
Control+Alt+Delete in Windows and DOS, which is always caught, or Control+Backspace on
Linux for terminating the X-Server. The syntax to define a new Button Key is as follows:
[confirm] <keycode>[+|-[*]<keycode>]*
confirm requests confirmation by a dialog box before the key strokes will be sent to the remote
host.
keycode is the key to be sent. Multiple key codes can be joined with a plus, or a minus sign.
The plus sign builds key combinations; all keys will be pressed until a minus sign or the end of
the combination is encountered. In this case all pressed keys will be released in reversed
sequence. So the minus sign builds single, separate key presses and releases. The star inserts
a pause with duration of 100 milliseconds.
33
5.4.2 Keyboard/Mouse
Host Interface
Enables the interface the mouse is connected to. You can choose between Auto for automatic
detection, USB for a USB mouse, or PS/2 for a PS/2 mouse.
Note: To use the USB and/or PS/2 interface you need the correct cabling between the
managed host and the managing device. If the managed host has no USB keyboard support
in the BIOS and you have connected the USB cable only, then you will have no remote
keyboard access during the boot process of the host. If USB and PS/2 are both connected
and you selected Auto as host interface, then USB will be selected if available, otherwise it
will revert to PS/2.
To enable USB remote keyboard access during the boot process of the host, the following
conditions must be fulfilled:
the host BIOS must have USB keyboard support
the USB cable must be connected or must be selected in the Host interface option
PS/2 Keyboard Model
Enables a certain keyboard layout. You can choose between Generic 101-Key PC for a
standard keyboard layout, Generic 104-Key PC for a standard keyboard layout extended by
three additional windows keys, Generic 106-Key PC for a Japanese keyboard, and Apple
Macintosh for the Apple Macintosh.
USB Mouse Type
Enables USB mouse type. Choose between MS Windows 2000 or newer for MS Windows
2000 or Windows XP, or Other Operating Systems for MS Windows NT, Linux, or OS X. In MS
Windows 2000 or newer mode the remote mouse is always synchronized with the local
mouse.
34
Mouse Speed
Auto mouse speed Use this option if the mouse settings on the host use an additional
acceleration setting. The IP KVM SWITCH CLASSIC USB tries to detect the acceleration
and speed of the mouse during the mouse sync process.
Fixed mouse speed Use a direct translation of mouse movements between the local and
the remote pointer.
You may also set a fixed scaling which determines the amount the remote mouse pointer is
moved when the local mouse pointer is moved by one pixel. This option only works when the
mouse settings on the host are linear. This means that there is no mouse acceleration involved.
To set the options, click on the Apply button.
5.4.3 Video
Miscellaneous Video Settings
Noise filter
This option defines how the IP KVM SWITCH CLASSIC USB reacts to small changes in the
video input signal. A large filter setting needs less network traffic and leads to a faster video
display, but small changes in some display regions may not be recognized immediately. A small
filter displays all changes instantly but may lead to a constant amount of network traffic even if
the display content is not really changing (depending on the quality of the video input signal). All
in all the default setting should be suitable for most situations.
Force Composite Sync (Required for Sun Computers)
To support signal transmission from a Sun machine, enable this option. If not enabled the
picture of the remote console will not be visible. To set the options, click Apply.
35
values are correct and you still have an option to access the IP
ACCESS KVM SWITCH
5.5 Device Settings
5.5.1 Network
The Network Settings panel allows network related parameters to be changed. Each parameter
will be explained below. Once applied the new network settings will immediately come into
effect.
Note: The initial IP configuration is usually done directly at the host system using the
special procedure described in Section 3, page 7.
Changing the network settings of the IP ACCESS KVM SWITCH CLASSIC might result in
losing connection to it. In case you change the settings remotely make sure that all the
IP auto configuration
With this option you can control if the IP KVM SWITCH CLASSIC USB should obtain its network
settings from a DHCP or BOOTP server. For DHCP, select dhcp, and for BOOTP select bootp.
If you choose none then IP auto configuration is disabled.
IP address

Set this option to allow access to ARA express using the Telnet Gateway (see the Section
called Telnet Console on page 23).
Disable Setup Protocol
Enable this option to exclude the IP KVM SWITCH CLASSIC USB from the setup protocol.
37
5.5.2 Dynamic DNS
A freely available Dynamic DNS service (dyndns.org) can be used in the following scenario (see
illustration below)
The IP KVM SWITCH CLASSIC USB is reachable via the IP address of the DSL router, which is
dynamically assigned by the provider. Since the administrator does not know the IP address
assigned by the provider, the IP KVM SWITCH CLASSIC USB connects to a special dynamic
DNS server in regular intervals and registers its IP address there. The administrator may
contact this server as well and pick up the same IP address belonging to his device.
The administrator has to register an IP KVM SWITCH CLASSIC USB that is supposed to take
part in the service with the Dynamic DNS Server and assign a certain hostname to it. He will get
a nickname and a password in return. This account information, together with the hostname, is
needed in order to determine the IP address of the registered IP KVM SWITCH CLASSIC USB .
You have to perform the following steps in order to enable Dynamic DNS:
Make sure that the LAN interface of the IP KVM SWITCH CLASSIC USB is properly
configured.
Open the Dynamic DNS Settings configuration dialog
Enable Dynamic DNS and change the settings according to your needs (see the next page).
38
Enable Dynamic DNS
Enables the Dynamic DNS service. This requires a configured DNS server IP address.
Dynamic DNS server
This is the server name where the IP KVM SWITCH CLASSIC USB registers itself in regular
intervals. At the time of writing, this is a fixed setting since only dyndns.org is currently
supported.
Hostname
This is the hostname of the IP KVM SWITCH CLASSIC USB that is provided by the Dynamic
DNS Server. (Use the whole name including the domain, e.g. testserver.dyndns.org not just
the actual hostname).
Username
You have registered this username during your manual registration with the Dynamic DNS
Server. Spaces are not allowed in the nickname.
Password
The password used during manual registration with the Dynamic DNS Server.
Check time
The IP KVM SWITCH CLASSIC USB registers itself in the Dynamic DNS server at this time.
Check interval
This is the interval for reporting again to the Dynamic DNS server by the IP KVM SWITCH
CLASSIC USB .
Note: The IP ACCESS KVM SWITCH CLASSIC has its own independent real time clock.
Make sure the time setting of the IP ACCESS KVM SWITCH CLASSIC switch is correct.
(See the Section called Date and Time on page 50)
39
5.5.3 Security
Force HTTPS
If this option is enabled, access to the web front-end is only possible using an HTTPS
connection. The IP KVM SWITCH CLASSIC USB will not listen on the HTTP port for incoming
connections.
If you want to create your own SSL certificate that is used to identify the IP KVM SWITCH
CLASSIC USB please refer to the section called Certificate on page 45.
KVM encryption
This option controls the encryption of the RFB protocol. RFB is used by the Remote Console to
transmit both the screen data to the administrator’s machine and the keyboard and mouse data
back to the host. If set to Off no encryption will be used. If set to Try, the applet tries to make an
encrypted connection. If connection establishment fails for any reason an unencrypted
connection will be used. If set to Force the applet tries to make an encrypted connection. An
error will be reported if connection establishment fails.
Group-based System Access Control
This is the IP filtering function, it keeps unauthorized hosts from accessing to the IP-KVM by
specifying IP filtering rules. It is important to fully understand what an IP filter is. If you don't fully
understand this, you will get unexpected results against your original plan.
40
Chain rule
The Chain rule determines whether the access from the hosts is allowed or not. It can be one of
these two values:
ACCEPT : access allowed
DROP : access not allowed
The rule can be configured to apply to a particular Group level (All, User, Super, Administrator).
When the IP-KVM receives a TCP packet, it will process the packet with the chain rule depicted
below. The process ordering is important; the packet will enter the chain at rule 1 first, if it meets
the rule then take action directly, otherwise go to chain rule 2.
Check the “Enable Group based System Access Control” to edit the rules
Users can add a new IP filtering rule by populating the fields in the new line by using Append or
Insert. Users can remove a rule by using Replace or Delete. Use Apply to save your changes.
41
5.5.4 Certificate
The IP KVM SWITCH CLASSIC USB uses the Secure Socket Layer (SSL) protocol for any
encrypted network traffic between itself and a connected client. During the connection
establishment the IP KVM SWITCH CLASSIC USB has to expose its identity to a client using a
cryptographic certificate.
This certificate and the underlying secret key is the same for all IP KVM SWITCH CLASSIC
USB units and certainly will not match the network configuration that will be applied to the IP
KVM SWITCH CLASSIC USB by its user. The certificate's underlying secret key is also used for
securing the SSL handshake. Hence, this is a security risk (but far better than no encryption at
all).
However, it is possible to generate and install a new certificate that is unique for a particular IP
KVM SWITCH CLASSIC USB . In order to do this, the IP KVM SWITCH CLASSIC USB is able
to generate a new cryptographic key and the associated Certificate Signing Request (CSR) that
needs to be certified by a certification authority (CA). A certification authority verifies that you
are the person you claim you are, and signs and issues a SSL certificate to you.
The following steps are necessary to create and install an SSL certificate for the IP KVM
SWITCH CLASSIC USB :
1. Create an SSL Certificate Signing Request using the panel shown in the screen shot
above. You need to fill out a number of fields that are explained on the next page. Once
this is done, click on the Create button to initiate the Certificate Signing Request
generation. The CSR can be downloaded to your administration machine with the
Download CSR button (see the illustration on the next page).
2. Send the saved CSR to a CA for certification. You will get the new certificate from the CA
after a more or less complicated traditional authentication process (depending on the
CA).
42
3. Upload the certificate to the IP KVM SWITCH CLASSIC USB switch using the Upload
button.
After completing these three steps, the IP KVM SWITCH CLASSIC USB has its own certificate
that is used to identify it to its clients.
Note: If you destroy the CSR on the IP ACCESS KVM SWITCH CLASSIC there is no way to
get it back! In case you deleted it by mistake, you have to repeat the three steps as described
previously.
Common name
This is the network name of the IP KVM SWITCH CLASSIC USB once it is installed in the user's
network It is identical to the name that is used to access the IP KVM SWITCH CLASSIC USB
with a web browser (without the “ http:// ” prefix). In case the name given here and the actual
network name differ, the browser will pop up a security warning when the IP KVM SWITCH
CLASSIC USB is accessed using HTTPS.
Organizational unit
This field is used for specifying to which department within an organization the IP KVM SWITCH
CLASSIC USB belongs.
Organization
The name of the organization to which the IP KVM SWITCH CLASSIC USB belongs.
Locality/City
The city where the organization is located.
State/Province
The state or province where the organization is located.
Country (ISO code)
The country where the organization is located. This is the two-letter ISO code, e.g. DE for
Germany, or US for the USA.
Challenge Password
Some certification authorities require a challenge password to authorize later changes on the
certificate (e.g. revocation of the certificate). The minimal length of this password is 4
characters.
43
Confirm Challenge Password
Confirmation of the Challenge Password
Email
The email address of a contact person that is responsible for the IP KVM SWITCH CLASSIC
USB and its security.
Key length
This is the length of the generated key in bits. 1024 bits are sufficient for most cases. Longer
keys may result in slower response time by the IP KVM SWITCH CLASSIC USB during
connection establishment.
5.5.5 Serial Port
The IP KVM SWITCH CLASSIC USB Serial Settings allow you to specify what device is
connected to the serial port and how to use it.
Configuration or console login
Do not use the serial port for any special function; use it only for the initial configuration
Modem
The IP KVM SWITCH CLASSIC USB offers remote access using a telephone line in addition to
the standard access over the built-in Ethernet adapter. The modem needs to be connected to
the serial interface of the IP KVM SWITCH CLASSIC USB .
Connecting to the IP KVM SWITCH CLASSIC USB using a telephone line allows you to set up
a dedicated point-to-point connection from your console computer to the IP KVM SWITCH
CLASSIC USB . In other words, the IP KVM SWITCH CLASSIC USB acts as an Internet
Service Provider (ISP) to which you can dial in. The connection is established using the Pointto-Point Protocol (PPP). Before you connect to the IP KVM SWITCH CLASSIC USB , make
44
sure you configure your console computer accordingly. For instance, on Windows based
operating systems you can configure a dial-up network connection, which defaults to the right
settings like PPP.
The Modem Settings panel allows you to configure remote access to the IP KVM SWITCH
CLASSIC USB using a modem. The meaning of each parameter will be described below. The
modem settings are part of the serial settings panel.
Serial line speed
The speed the IP KVM SWITCH CLASSIC USB is communicating with the modem. Most
modems available today will support the default value of 115200 bps. In case you are using
an old modem and discovering problems try to lower this speed.
Modem Init String
The initialization string used by the IP KVM SWITCH CLASSIC USB to initialize the modem.
The default value will work with all modern standard modems directly connected to a
telephone line. In case you have a special modem or the modem is connected to a local
telephone switch that requires a special dial sequence in order to establish a connection to
the public telephone network, you can change this setting by entering a new string. Refer to
your modem’s manual about the AT command syntax.
Modem server IP address
This IP address will be assigned to the IP KVM SWITCH CLASSIC USB during the PPP
handshake. Since it is a point-to-point IP connection virtually every IP address is possible
but you must make sure, it is not interfering with the IP settings of the IP KVM SWITCH
CLASSIC USB and your console computer. The default value will work in most cases.
Modem client IP address
This IP address will be assigned to your console computer during the PPP handshake.
Since it is a point-to-point IP connection virtually every IP address is possible but you must
make sure, it is not interfering with the IP settings of the IP KVM SWITCH CLASSIC USB
switch and your console computer. The default value will work in most cases.
Pass-through access to serial port via Telnet
Using this option, it is possible to connect an arbitrary device to the serial port and access it
(assuming it provides terminal support) via Telnet. Select the appropriate options for the serial
port and use the Telnet Console, or a standard Telnet client to connect to the IP KVM SWITCH
CLASSIC USB .
45
5.5.6 Date And Time
Here you can set the internal real-time clock of the IP KVM SWITCH CLASSIC USB . You can
adjust the clock manually or use an NTP timeserver. Without a timeserver your time setting will
be lost if the IP KVM SWITCH CLASSIC USB is powered down for more than a few minutes. To
avoid this, you can use an NTP timeserver which sets up the internal clock automatically to the
current UTC time. Because the NTP server time is always UTC, there is a setting that allows
you to set up a static offset to get your local time.
Note: The IP ACCESS KVM SWITCH CLASSIC does not adjust to daylight saving time
automatically. So you have to set up the UTC offset according to the local conventions of
your country.
46
5.5.7 Event Log
Important events like a login failure or a firmware update are logged to a selection of logging
destinations. Each of those events belongs to an event group, which can be activated
separately.
In the Event Log Settings you can choose how many log entries are shown on each page.
Furthermore, you can clear the log file here.
List logging enabled
The common way to log events is to use the internal log list of the IP KVM SWITCH CLASSIC
USB . To show the log list, click on Event Log on the Maintenance page.
Since the IP KVM SWITCH CLASSIC USB ’s system memory is used to save all the
information, the maximum number of possible log list entries is restricted to 1000 events. Every
entry that exceeds this limit overrides the oldest one.
Note: If the reset button on the HTML front end is used to restart the IP ACCESS KVM
SWITCH CLASSIC all logging information is saved permanently and is available after the IP
ACCESS KVM SWITCH CLASSIC has been started. If the IP ACCESS KVM SWITCH
CLASSIC loses power or a hard reset is performed, all logging data will be lost. To avoid this,
use one of the log methods described below.
NFS Logging enabled
Defines an NFS server to write all logging data to a file that is located there. To write logging
data from multiple IP KVM SWITCH CLASSIC USB units to only one NFS share, you have to
define a file name that is unique for each device. When you change the NFS settings and press
Apply, the NFS share will be mounted immediately. That means, the NFS share and the NFS
server must be filled with valid sources or you will get an error.
47
SMTP Logging enabled
With this option, the IP KVM SWITCH CLASSIC USB is able to send Emails to an address
given by the Email address text field in the Event Log Settings. These mails contain the same
description strings as the internal log file and the mail subject is filled with the event group of the
occurred log event. In order to use this log destination you have to specify an SMTP server that
has to be reachable from the IP KVM SWITCH CLASSIC USB and that needs no authentication
at all (<serverip>:<port>).
SNMP Logging enabled
If this is activated, the IP KVM SWITCH CLASSIC USB sends an SNMP trap to a specified
destination IP address every time a log event occurs. If the receiver requires a community
string, you can set it in the appropriate text field. Most of the event traps only contain one
descriptive string with all information about the log event. Only authentication and host power
events have a trap class that consists of several fields with detailed information about the
occurred event. To receive these SNMP traps, any SNMP trap listener may be used.
Warning In contrast to the internal log file on the IP KVM SWITCH CLASSIC USB , the size of
the NFS log file is not limited. Every log event will be appended to the end of the file so it grows
continuously, so you may have to delete it or move it from time to time.

5.6.3 Update Firmware
The IP KVM SWITCH CLASSIC USB is a complete standalone computer. The software it runs
is called the firmware. The firmware of the IP KVM SWITCH CLASSIC USB can be updated
remotely in order to install new functionality or special features.
50
A new firmware update is a binary file which can be sent to you by email from the Technical
Support team of LINDY.
Updating the firmware is a three-stage process:
1. The new firmware file is uploaded to the IP KVM SWITCH CLASSIC USB . In order to do
this you need to select the file on your local system using the Browse button on the Upload
Firmware panel. Once the firmware file has been uploaded it is checked whether it is a valid
firmware file and whether there were any transmission errors. In case of any error the
Upload Firmware function will be aborted.
2. If everything went well you will see the Update Firmware panel. The panel shows you the
version number of the currently running firmware and the version number of the uploaded
firmware. Pressing the Update button will replace the old version with the new one.
Note: This process is not reversible and may take some minutes. Make sure the IP ACCESS
KVM SWITCH CLASSIC’s power supply will not be interrupted during the update process.
3. After the firmware has been stored, the panel will request you to reset the IP KVM SWITCH
CLASSIC USB manually. Half a minute after the reset the IP KVM SWITCH CLASSIC USB
will run with the new firmware version and should be accessible. However, you will be
required to login once again.
Note: The three-stage firmware update process and consistency check means that making a
mistake when updating the firmware is very unlikely. However, we recommend only
experienced users or administrators should perform the firmware update. Make sure the IP
ACCESS KVM SWITCH CLASSIC’s power supply will not be interrupted during the update
process!
51
5.6.4 Unit Reset
This section allows you to reset specific parts of the device. This involves the keyboard and
mouse, the video engine and the IP KVM SWITCH CLASSIC USB itself.
Resetting the unit itself is mainly needed to activate a newly updated firmware. It will close all
current connections to the administration console and to the Remote Console.
The whole process will take about half a minute. Resetting sub devices (e.g. the video engine)
will take a few seconds only and does not result in connections closing. To reset individual IP
KVM SWITCH CLASSIC USB functionality, click on the Reset button.
Note: Only the super user is allowed to reset the IP KVM SWITCH CLASSIC USB .
52
6. Troubleshooting
Q 001: The remote mouse doesn’t work or is not synchronized
A 001: Make sure the mouse settings in IP KVM SWITCH CLASSIC USB match the mouse
model. Use the Intelligent Sync option from the Mouse Handling sub menu of the Remote
Console Options menu.
Q 002: The video quality is bad or the picture is grainy
A 002: Try to correct the brightness and contrast settings (see Page 19) until they are out of a
range where the picture looks grainy. Use the auto adjustment feature to correct a flickering
video.
Q 003: Login on IP KVM SWITCH CLASSIC USB switch fails.
A 003: Was the correct combination of user and password given? The default user name is
super and the password is pass. Furthermore, your browser must be configured to accept
cookies.
Q 004: The Remote Console window can’t connect to the IP KVM SWITCH CLASSIC USB .
A 004: Possibly a firewall prevents access to the Remote Console. Make sure the TCP port
numbers 443 or 80 are open for incoming TCP connections. Install the latest version of Java
Virtual Machine,
Q 005: No connection can be established to the IP KVM SWITCH CLASSIC USB .
A 005: Check whether the network connection is working in general (ping the IP address of IP
KVM SWITCH CLASSIC USB ). If not, check the network hardware. Is the IP KVM SWITCH
CLASSIC USB powered on? Check whether the IP address of IP KVM SWITCH CLASSIC USB
switch and all other IP related settings are correct! Also verify that all the IP infrastructure of
your LAN, like routers etc., is correctly configured.
Q 006: Special key combinations, e.g. ALT+F2, ALT+F3 are intercepted by the console
system and not transmitted to the host.
A 006: You have to define a so-called Button Key. This can be done in the Remote Console
settings.
Q 007: In the browser the IP KVM SWITCH CLASSIC USB switch pages are inconsistent.
A 007: Check your browser cache settings. Especially make sure that the cache settings are not
set to something like ‘never check for newer pages’. Otherwise the IP KVM SWITCH CLASSIC
USB pages may be loaded from your browser cache and not from the unit.
Q 008: Windows XP doesn’t awake from standby mode
A 008: This could be a Windows XP problem. Try not to move the mouse while XP goes into
standby mode.
53
Q 009: Using MacOS X an HTTPS connection fails
A 009: You have to install the IP KVM SWITCH CLASSIC USB certificate using our certificate
installer, available on the utility CD. Please refer to the instructions on this CD for further
information on how to install the certificate.
Q 010: Can’t upload the signed certificate in Mac OS X
A 010: If an ‘internal error’ occurs while uploading the signed certificate either change the
extension of the file to .txt or add a file helper using the Internet Explorer preferences for this
type of file. Make sure that the encoding is plain text and the checkbox ‘use for outgoing’ is
checked. Another possibility is to use a Mozilla based browser.
Q 011: Every time I open a dialog box with some buttons the mouse pointers are not
synchronous anymore
A 011: Please check, if you have an option like ‘Automatically move mouse pointer to the
default button of dialog boxes’ enabled in the mouse settings of the operating system. This
option needs to be disabled.

WEEE (Waste of Electrical and Electronic Equipment),
Recycling of Electronic Products
Europe
In 2006 the European Union introduced regulations (WEEE) for the collection and recycling of all waste electrical and electronic
equipment. It is no longer allowable to simply throw away electrical and electronic equipment. Instead, these products must
enter the recycling process.
Each individual EU member state has implemented the WEEE regulations into national law in slightly different ways. Please
follow your national law when you want to dispose of any electrical or electronic products. More details can be obtained from
your national WEEE recycling agency.
Germany
Die Europäische Union hat mit der WEEE Direktive umfassende Regelungen für die Verschrottung und das Recycling von
Elektro- und Elektronikprodukten geschaffen. Diese wurden im Elektro- und Elektronikgerätegesetz – ElektroG in deutsches
Recht umgesetzt. Dieses Gesetz verbietet das Entsorgen von entsprechenden, auch alten, Elektro- und Elektronikgeräten über
die Hausmülltonne!
Dies ist ein B2B Produkt. Entsprechend dem deutschen ElektroG hat der gewerbliche Endverwender dieses Gerät zum Zweck
der Verschrottung entweder der LINDY-Elektronik GmbH zum Recycling zurück zu geben (kostenlose Rücknahme) oder es auf
eigene Kosten einem geordneten Recycling zuzuführen.
France
En 2006, l'union Européenne a introduit la nouvelle réglementation (DEEE) pour le recyclage de tout équipement électrique et
électronique.
Chaque Etat membre de l’ Union Européenne a mis en application la nouvelle réglementation DEEE de manières légèrement
différentes. Veuillez suivre le décret d’application correspondant à l’élimination des déchets électriques ou électroniques de
votre pays.
Italy
Nel 2006 l’unione europea ha introdotto regolamentazioni (WEEE) per la raccolta e il riciclo di apparecchi elettrici ed elettronici.
Non è più consentito semplicemente gettare queste apparecchiature, devono essere riciclate. Ogni stato membro dell’ EU ha
tramutato le direttive WEEE in leggi statali in varie misure. Fare riferimento alle leggi del proprio Stato quando si dispone di un
