9 Configuration
9.1 Network configuration using PSetup utility
After the initial setup, the CAT5 8-PORT/16-PORT IP-KVM can be managed via
the Internet using a standard browser that lets you control the device/s attached
to it. However, to configure the CAT5 8-PORT/16-PORT IP-KVM’s network
access, the user must first run the PSetup Utility software that is included on the
CD-ROM included in your package.
The PSteup Utility lets you set up the CAT5 8-PORT/16-PORT IP-KVM’s network
configuration (IP address, Subnet mask, DHCP, etc) from any computer that is
connected to the same subnet. This program is also useful if you ever need to
view or change the network settings of the unit. If the initial or default basic
configuration does not meet your requirements, use the PSetup program to
change the configuration to suit your needs.
When open the PSetup Utility on your computer, the PSetup Utility window (see
the screenshot below) will appear.
To use the PSetup Utility, please follow the procedures described below.
Finding the CAT5 8-PORT/16-PORT IP-KVM on your network via the Psetup
Utility:
1) Make sure the computer you are using to set up the CAT5 PORT/16-PORT
IP-KVM is connected to the same local network that the CAT5 8-PORT/16-PORT
IP-KVM is connected to.
2) Open the PSetup Utility on your computer. The PSetup Utility window (see
the screenshot above) will appear.
Page 33
--
33
3) Use the PSetup Utility to search for the CAT5 8-PORT/16-PORT IP-KVM on
your network:
a) Click the Refresh Devices button to show the MAC addresses of all
connected devices on your network.
b) Find the MAC address of the CAT5 8-PORT/16-PORT IP-KVM by clicking
on the “Device MAC Address” drop-down box. Select your device’s MAC
address from the dropdown list.
c) After selecting your CAT5 8-PORT/16-PORT IP-KVM’s MAC address,
click Query Device to view the device’s Network Configuration in the top
right area.
d) By default, the DHCP function is disabled, and “None” will be selected for
“IP auto configuration”. This means there would initially be a static IP
address for the device. You can now configure the CAT5 8-PORT/16-PORT
IP-KVM to use a static IP address, or you can turn on DHCP to
automatically obtain an IP address from a DHCP server on your network.
Both configurations are described in the following steps.
Note: We recommend that you manually set up a static IP address that is
linked to the MAC address of your CAT5 8-PORT/16-PORT IP-KVM.
Setting up a static IP via the PSetup Utility:
1) Make sure that the correct MAC address is selected in the “Device” field at
the top left of the PSetup Utility window.
2) Click Query Device (at bottom right) to view the device’s Network
Configuration in the top right area.
3) In the “IP auto configuration” line at the top right, select “None”.
4) Enter the IP address, subnet mask, and gateway you want the CAT5
8-PORT/16-PORT IP-KVM to use.
5) In the Authentication area, enter the Super User login and password for the
CAT5 8-PORT/16-PORT IP-KVM. The default login is super, and the default
password is pass.
6) Click the Setup Device button. If the Super User login and password are
correct, a“Successfully configured device” message will appear.
7) The CAT5 8-PORT/16-PORT IP-KVM’s web management interface can now
be accessed via the Internet by simply browsing to the same IP address
from a web browser.

OK
Enabling DHCP to get a dynamic IP address:
If you have installed the CAT5 8-PORT/16-PORT IP-KVM on the subnet
(intranet) of a DHCP server, or the subnet of a router that supports DHCP, you
can use the PSetup Utility to find the dynamic IP address of the CAT5
8-PORT/16-PORT IP-KVM. DHCP automatically assigns a dynamic IP address
to the CAT5 8-PORT/16-PORT IP-KVM. This allows a device to be automatically
assigned an IP, eliminating the need for intervention by a network administrator,
who would otherwise have to manually assign the CAT5 8-PORT/16-PORT
IP-KVM a static IP address.
1) Before connecting the CAT5 8-PORT/16-PORT IP-KVM to your network,
make sure you complete the configuration of the network’s DHCP server.
The network’s router may be acting as your network’s DHCP server, or
another device may be acting as the DHCP server.
2) Connect the CAT5 8-PORT/16-PORT IP-KVM to your network by using an
Ethernet cable. Connect one end to your network, and the other end to the
Ethernet port of the CAT5 8-PORT/16-PORT IP-KVM.
3) The DHCP function of the router/server will now automatically assign an IP
address to the CAT5 8-PORT/16-PORT IP-KVM.
4) Make sure that the computer you are using to set up the CAT5
8-PORT/16-PORT IP-KVM is connected to the same network that the CAT5
8-PORT/16-PORT IP-KVM is connected to.
5) Open the PSetup Utility on your computer. The PSetup Utility window (see
the screenshot above) will appear.
Page 35
--
35
6) Use the PSetup Utility to search for the CAT5 8-PORT/16-PORT IP-KVM on
the network (see the image below):
a) Click the Refresh Devices button to detect all connected devices.
b) Find the MAC address of the CAT5 8-PORT/16-PORT IP-KVM by
clicking on the “Device MAC Address” drop-down box. Select your
device’s MAC address from the dropdown list.
c) After selecting your CAT5 8-PORT/16-PORT IP-KVM’s MAC address,
click Query Device (see the screenshot below) to view the device’s
Network Configuration in the top right area.
d) In the “IP auto configuration” line at the top right, select “DHCP”.
e) In the Authentication area, enter the Super User login and password for
the CAT5 8-PORT/16-PORT IP-KVM. The default login is super, and
the default password is pass.
f) Click the Setup Device button. If the Super User login and password
are correct, a “Successfully configured device” message will appear.
g) The CAT5 8-PORT/16-PORT IP-KVM will now try to contact a DHCP
server in the subnet to which it is physically connected. If contact is
made with a DHCP server, it will provide the CAT5 8-PORT/16-PORT
IP-KVM with a dynamic IP address, subnet mask, and gateway.
h) Click the Query Device button again, and the device’s dynamic IP
address and other network information should now be visible in the
Network Configuration field (see the screenshot below).
Page 36
36
Notes:
BOOTP, a static configuration protocol, uses a table that maps
IP addresses to physical addresses.
DHCP, an extension to BOOTP that dynamically assigns
configuration information. DHCP is backward compatible with
BOOTP.
The factory default settings for the CAT5 8-PORT/16-PORT IP-KVM unit are
as below:
DHCP: Disabled
Default IP address: 192.168.0.70
Default Subnet mask: 255.255.255.0
IN SHORT: If the currently selected device has DHCP selected for its Network
Configuration, click OK and the CAT5 8-PORT/16-PORT IP-KVM will try to
contact a DHCP server in the network to which it is physically connected. If
contact is made with a DHCP server, it will provide the CAT5 8-PORT/16-PORT
IP-KVM with a dynamic IP address, gateway address and subnet mask.
Changing your device’s password through the PSetup Utility:
To change your password with the PSetup Utility, select your device from the
Device MAC Address drop-down box, then in the “Authentication” section in the
bottom-left part of the window, enter the Super User login and current password
for your CAT5 8-PORT/16-PORT IP-KVM. The default login is super, and the
default password is pass. Now enter your new password in the “New Super User
password” text box, and enter it again in the “New Password (confirm)” text box
to confirm it.
To save your new password and close the window, click the OK button.
Otherwise, click the Cancel button.
WARNING:
Please make sure that you change the default Super User password
immediately after you have installed and accessed your CAT5
8-PORT/16-PORT IP-KVM for the first time. Leaving the password as it is
represents a severe security risk and may result in unauthorized access to
the CAT5 8-PORT/16-PORT IP-KVM as well as the entire Remote console
system and connected devices. The password can be changed in the setup
program (as described above) or online on the browser-based Web
Management GUI. Make sure you write your password down in a safe
place.

9.2 Configuration Setup via Serial Console
For connecting to serial-based terminals, the CAT5 8-PORT/16-PORT IP-KVM has
a serial cable interface (for setup on the Host side). This connector is compliant
with the RS-232 serial line standard. The serial connection has to be configured
with the parameters given in Table below.
When configuring your device from a serial-based terminal such as Hyper Terminal,
reset the CAT5 8-PORT/16-PORT IP-KVM and immediately press the “ESC” key.
You will see some devices information, and a “=>” prompt. Type in “config”, press
the “Enter” key and wait a few seconds for the configuration questions to appear.
As you proceed, you will be prompted for the following settings one after the other.
To accept the default values shown in square brackets below, press the “Enter”
key.
IP auto configuration: None
IP address: [192.168.0.70]
Net mask: [255.255.255.0]
Gateway: [0.0.0.0] -- (0.0.0.0 for none)
IP auto-configuration
You can specify whether the CAT5 8-PORT/16-PORT IP-KVM should get its
network settings from a DHCP or BOOTP server. To enable IP auto-configuration
via DHCP, type “dhcp” in the “IP auto-configuration” line. For BOOTP, type “bootp”.
Press “Enter” to apply the setting.
If you do not specify either of these two options, IP auto-configuration will be
disabled (it will be static IP configuration) and you will be asked for the following
network settings:
Page 38
38
IP address
Enter the IP address for the CAT5 8-PORT/16-PORT IP-KVM. This option is only
available if IP auto-configuration is disabled.
Net mask
Enter the subnet mask of the connected IP subnet. This option is only available if
IP auto-configuration is disabled.
Gateway address
Enter 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. This option is only available if IP
auto-configuration is disabled.
9.3 Keyboard, Mouse, and Video configuration
Between the CAT5 8-PORT/16-PORT IP-KVM 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.
9.3.1 CAT5 8-PORT/16-PORT IP-KVM keyboard settings
The keyboard model emulated by the CAT5 8-PORT/16-PORT IP-KVM must be
set properly in order for keystrokes received by the Host computer to match the
ones sent by a Remote computer. View these settings in the CAT5
8-PORT/16-PORT IP-KVM’s Web Management GUI.
9.3.2 Remote Mouse Settings
A common problem with KVM devices is the synchronization between the
Host-side and Remote-side mouse cursors. The CAT5 8-PORT/16-PORT
IP-KVM resolved this problem with an intelligent synchronization algorithm.
There are two mouse modes available on the CAT5 8-PORT/16-PORT IP-KVM:
Auto mouse speed
The automatic mouse speed mode tries to detect the speed and acceleration
settings of the host system automatically. See the section below for a more
detailed explanation.
Page 39
--
39
Fixed mouse speed
This mode just translates the mouse movements from the Remote Console so
that one pixel of movement will result in “n” number of pixel moves on the Host
system. The value of “n” is adjustable. Please note that this works only when
mouse acceleration settings are turned off on the Host computer.
9.3.3 Automatic mouse speed and mouse synchronization
The automatic mouse speed mode performs the speed detection during mouse
synchronization. Whenever the Host-side and Remote-side mouse cursors move
synchronously or not, there are two ways for re-synchronizing Host-side and
Remote-side mouse cursors:
Fast Sync
The fast synchronization is used to correct a temporary, but fixed skew. Choose
the option using the Remote Console options menu or press the mouse
synchronization hot-key sequence in case you defined one.
Intelligent Sync
If the fast sync does not work or the mouse settings have been changed on the
host system, use the intelligent resynchronization. This method takes more time
than the fast Sync. It can be accessed with the appropriate item in the Remote
Console option menu. The intelligent synchronization requires a correctly
adjusted picture. Use the auto adjustment function to setup the picture, and
make sure that there are no window at the top left corner of the remote desktop
that are able to change the mouse cursor shape from the normal state. 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
changed recently.
Note: At first start, if the local mouse pointer is not synchronized with the remote
mouse pointer, press the Auto Adjust Button once.
9.3.4 Single and Double Mouse Mode
The CAT5 8-PORT/16-PORT IP-KVM features two different mouse
synchronization modes: Double Mouse mode, and Single Mouse mode.
Double Mouse Mode: In this mode, both the Remote and Host mouse pointers
are visible, allowing you to control the Host computer on your Remote computer
while allowing you to move the mouse outside the Remote Console window. In this
Page 40
40
mode, the mouse pointers may need to be synchronized in order to ensure they
are pointing at the same position on your Host computer screen. You can define a
hotkey to quickly sync the two mouse pointers.
Single Mouse Mode: In this mode, only one mouse pointer is visible – the Remote
computer pointer. On the Remote computer, when you click on the Remote
Console window, your mouse pointer will be “captured”, and all mouse movement
will be inside the Remote Console window only. In order to “free” the Remote
computer’s mouse pointer, you will need to use a hotkey to “release” the mouse
pointer from the Remote Console window. The default hotkey for this is “Alt + F12”.
9.3.5 Host system mouse settings
While the CAT5 8-PORT/16-PORT IP-KVM supports accelerated mouse
movements and is able to synchronize the Host-side pointer with the Remote-side
mouse pointer, there are a few operating systems that limit this functionality and
may prevent this synchronization from working properly. If you experience issues
with mouse synchronization, please try the following:
Special Mouse Driver
Specific mouse drivers may influence the synchronization process and impede
synchronization of dual mouse pointers. If this happens, make sure you are not
using a special vendor-specific mouse driver on your Host system.
Windows Settings
All versions of Windows (on Host computer): In the CAT5 8-PORT/16-PORT
IP-KVM’s web GUI, select “Auto Mouse Speed” (in KVM Settings >
Keyboard/Mouse).
Windows 2000 (on Host computer): On the Host computer, you will need to go to
Control Panel > Mouse > Motion > Acceleration and make sure “Improve Mouse
Acceleration” is disabled.
Windows XP/Vista/7 (on Host computer): On the Host computer, you will need to
go to Control Panel > Mouse > Pointer Options and make sure “Enhance Pointer
Precision” is disabled.
Active Desktop
If the “Active Desktop” feature of Microsoft Windows is enabled, do not use a plain
background. Instead, use a wallpaper image. Alternatively, disable “Active
Desktop” completely.
Page 41
--
41
Mac OS X Settings
Mac OS X (on Host computer): If the host computer is running on any version
of Mac OS X, we recommend using Single Mouse mode.
SUN Solaris Settings
SUN Solaris (on Host computer): If the host system is running SUN Solaris,
adjust the mouse settings of the system by entering “xset m 1” into the console, or
use the CDE Control Panel to set the mouse to “1:1, no acceleration”. Alternatively,
you could use the Single Mouse mode only. On SUN operating systems, Double
Mouse Mode only functions if you use SUN JVM 1.5 or higher.
9.3.6 Video Modes
The CAT5 8-PORT/16-PORT IP-KVM recognizes a limited number of common
video modes. If you run X11 on the host system, please do not use any custom
mode lines with special video modes. If you do, the CAT5 8-PORT/16-PORT
IP-KVM may not be able to detect them. We recommend using any of the standard
VESA video modes instead.

10 Usage
10.1 Prerequisites
The CAT5 8-PORT/16-PORT IP-KVM features an embedded operating system
and applications that support two standardized interfaces – HTTP/HTTPS and
Telnet. This chapter will describe both these interfaces in detail, as well as how
to use them. Both interfaces are accessed using the TCP/IP protocol family.
HTTP/HTTPS
Full access is provided by the embedded web server. The CAT5
8-PORT/16-PORT IP-KVM environment can be entirely managed by using a
standard web browser. You can access the CAT5 8-PORT/16-PORT IP-KVM
by using the non-secure HTTP protocol, or by using the encrypted HTTPS
protocol. For security purposes, we suggest using HTTPS whenever possible.
Telnet
A standard Telnet client can be used to access an arbitrary device that is
connected to the CAT5 8-PORT/16-PORT IP-KVM's serial port in
terminal mode.
HTTP as the Primary Interface
The primary interface of the CAT5 8-PORT/16-PORT IP-KVM is the HTTP
interface. This will be covered extensively in this chapter. Other interfaces are
addressed in sub-topics.
In order to open the Remote Console window of your managed host system, the
browser must support version 1.5 or above of the Java Runtime Environment. If
the browser has no Java support (such as on a small handheld device), you can
still manage your CAT5 8-PORT/16-PORT IP-KVM by using the administration
forms displayed by the browser itself.
For a secure connection to the CAT5 8-PORT/16-PORT IP-KVM, we
recommend the following browsers versions:
Microsoft Internet Explorer version 6.0 or higher
Netscape Navigator 7.0
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 browser that supports a 128-bit passkey. Some older
Page 43
--
43
browsers do not have a strong 128-bit encryption algorithm.
If you are using Internet Explorer, click on the top toolbar menu option marked
“?”, then click on “About Internet Explorer” to see the current “Cipher Strength”
(the passkey length that is currently activated). The dialog box contains a link
that leads you to information on how to upgrade your browser to a more powerful
encryption scheme. The screenshots below shows the dialog boxes presented
by IE 8 and IE 6.
Figure 33: The Internet Explorer displaying the encryption key length
Newer web browsers generally support strong encryption by default.

10.2 Log in/out CAT5 8-PORT/16-PORT IP-KVM
10.2.1 Log in the CAT5 8-PORT/16-PORT IP-KVM
The CAT5 8-PORT/16-PORT IP-KVM has three levels of access privileges:
User Name
Default
Password
Access Privileges
super
(factory default)
pass
(factory default)
Full access
administrator (user-define)
Partial rights to configure the settings of critical functions
user (user-define)
Rights to access basic functions of the Open Remote Console
The super user can add or remove a user easily via the web pages of User
Management > Users. Please refer to Addendum C for details on what access
rights are assigned for each user level.
Launch your web browser and type in the IP address that you configured for your
CAT5 8-PORT/16-PORT IP-KVM during the installation process. The address
might be an IP address or a domain name, in the case where you have given your
CAT5 8-PORT/16-PORT IP-KVM a symbolic name in the DNS. For instance, type
the following in the URL field of your browser when establishing a non-secured
connection:
http://<IP address of IP-KVM>
When using a secure connection, type in:
https://<IP address of IP-KVM>
The browser will open the IP-KVM login page, as shown below:
If you connect to the CAT5 8-PORT/16-PORT IP-KVM unit, the CAT5
8-PORT/16-PORT IP-KVM system (via its web server, Telnet server, or SSH
server) will prompt you to enter your username and password in order to access
the system. If this is the first time you log in, log in with the factory default
username super and password pass, after which you will be prompted to change
the default password.
Page 45
--
45
WARNING:
Please make sure that you change the default Super User password
immediately after you have installed and accessed your CAT5
8-PORT/16-PORT IP-KVM for the first time. Leaving the password as it is
represents a severe security risk and may result in unauthorized access to
the CAT5 8-PORT/16-PORT IP-KVM as well as the entire Host system and
connected devices!
NOTE:
Your web browser has to be set up to accept cookies, or else you won’t be
able to log in.
Navigation
After successfully logging into the CAT5 8-PORT/16-PORT IP-KVM, the main
page of the IP-KVM web management GUI will appears. This page consists of
three parts; each of them contains specific information. The buttons on the upper
side are clickable shortcuts to go to the main page, to open the Remote Console
or to log out. The left-hand column displays the configuration categories. Clicking
on each configuration category will give a submenu of configuration/command
options.
Page 46

Return to the main page of the IP-KVM’s web GUI
Open the IP-KVM Remote Console
Log out and exit from the IP-KVM’s web GUI.
NOTE:
If there is no user activity for 30 minutes, the CAT5 8-PORT/16-PORT IP-KVM will log you
out automatically. Clicking on any of the menu items will bring you back to the login screen.
Remote Console Preview
Click on Click to open to start the remote console redirection
Click on Refresh to refresh the picture.
10.2.2 Log out from the CAT5 8-PORT/16-PORT IP-KVM
This link logs out the current user and presents a new login screen. Please note
that an automatic logout will be performed in case there is no activity for 30
minutes.
10.3 The Remote Console
Page 47
--
47
The Remote Console is the redirected screen, keyboard and mouse of the
remote host system that CAT5 8-PORT/16-PORT IP-KVM controls.
The Remote Console window is a Java Applet that tries to establish its own TCP
connection to the CAT5 8-PORT/16-PORT IP-KVM. The protocol that is running
over this connection is neither HTTP nor HTTPS, but RFB (Remote Frame
Buffer Protocol). By default, RFB tries to establish a connection to TCP port 443.
Your local network environment must allow this connection to be made, i.e. your
firewall and, in case you have a private internal network, your NAT (Network
Address Translation) settings have to be configured accordingly.
If the CAT5 8-PORT/16-PORT IP-KVM is connected to your local network
environment and your connection to the Internet is available by using a proxy
server without NAT being configured, it is unlikely that the Remote Console will
be able to establish the desired connection. This is because modern web proxies
are not capable of relaying the RFB protocol.
If you experience any problems, please consult your network administrator to
configure an appropriate networking environment.
10.3.1 Main Window of Remote Console
To open the KVM console, either click on the icon Console or Remote Control
> KVM Console of the menu entry in the left-hand column or click the Click to
open link at the top of the Remote Console picture on the right.
Activating the Remote Console function opens a new window on the Remote-side
user’s screen. This window displays the screen content of your host system. The
Page 48
48
Remote Console will behave exactly in the same way as if you were sitting in front
of it. This means you can use your keyboard and mouse in the usual way. However,
be aware of the fact that the feedback from
keyboard and mouse actions on the
Host system will be slightly delayed. The delay depends on the bandwidth of the
between you and the CAT5 8-PORT/16-PORT IP-KVM.
Differences between the Remote computer’s keyboard layout and the Host
computer’s keyboard settings may lead to some problems. For example, if the
Remote-side user uses a German keyboard layout and the Host system is set up
for an English keyboard layout, special German-specific keys on the German
keyboard will not work as expected. Instead, the keys will have the same effect
as those of an English-layout keyboard. The Remote-side user can circumvent
such problems by adjusting the keyboard settings of the Host system to have the
same mapping as the Remote user’s keyboard.
The Remote Console window always tries to show the remote screen with its
optimal size. That means it will resize the window to fit the Remote-side user’s
screen by default 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.
NOTE:
The Remote Console window is just another window on the Remote-side user’s
system. To get control of the Host system, the Remote-side user first needs to
click inside the Host window to give it focus. In Single Mouse mode, this action
will capture the mouse pointer, so all mouse input is directed to the Host
computer, and making the Remote computer’s mouse pointer disappear. To
release the mouse from this captured state, use the Mouse hotkey. The default
hotkey for this is Alt+F12, but this hotkey can be reconfigured manually.
10.3.2 Control Bar of Remote Console
The upper part of the Remote Console window contains a control bar. By clicking on
the icons on this bar, you can view the state of the Remote Console and adjust the
local Remote Console settings. The following is a description for each control:
Figure 34: Remote Console Control Bar
Page 49
--
49
Ctrl+Alt+Delete
Click this button to send the “Control Alt Delete” key-sequence command to the remote
system. (Also, see section 5.4.1 for configuring new key-sequence buttons).
Drive Redirection button
Click this button to open the Drive Redirection options at the top of the Remote Console
window (see the screenshot below). For more details, see section 11.2.
Auto Adjust button
If the quality of the Remote Console video is bad, or if the Remote Console window is
distorted in some way, click this button and wait a few seconds while the CAT5
8-PORT/16-PORT IP-KVM tries to detect the video mode of the VGA connection of the
Host system to the CAT5 8-PORT/16-PORT IP-KVM. Once detection is complete, the
CAT5 8-PORT/16-PORT IP-KVM will adjust itself for the best possible video quality.
Sync mouse
Clicking this button activates the mouse synchronization process. Choose this option to
synchronize the Host-side mouse cursor with the Remote-side mouse cursor. (Double
Mouse Mode only)
.
Single/Double mouse mode
Clicking this button switches between Single Mouse Mode (where only the Host-side
mouse pointer is visible) and the Double Mouse Mode (where the Host-side and
Remote-side mouse pointers are both visible and need to be synchronized). On SUN
operating systems, Double Mouse Mode only functions if you use SUN JVM 1.5 or higher.
We recommend using only Single Mouse Mode on Mac OS X systems. For more
information on Single and Double Mouse mode and troubleshooting mouse
synchronization, please refer to Section 9.3.4.
Page 50

Options
Click on this button to open the “Options” menu.
Figure 35: Remote Console Options Menu
A short description of the options as follows.
Monitor Only
Click this command to toggle the Monitor Only function on or off. If this function is
switched on, the Remote-side user can only monitor the Host-side user’s console, and
cannot control it.
Exclusive Access
If a user has the appropriate administration rights, he or she can force a shutout of all
other Remote-side users from a Host system, so that he or she alone can control the
Host systems. No one can re-open the selected Remote Consoles until this user
deactivates Exclusive Access, or logs off.
The Access Mode icon in the status bar at the bottom of the screen will indicate the current status of the Exclusive Access function (see the screenshot below).
Figure 36: Remote Console Exclusive Mode
Screenshot to Clipboard
Click on this menu item to take a screenshot of the Host view window. The screenshot
will be saved to the clipboard of the Remote computer.
Scaling
Page 51
--
51
This allows the Remote-side user to scale down the Remote Console window on
their monitor. The mouse and keyboard controls will stay the same, but the
scaling algorithm will not preserve all the display details.
When you select 25%, 50%, or 100% scaling, the size of the Remote Console
window is calculated according to the Host video settings and the scaling
algorithm. When you select “Scale to fit”, the Host video display will fit into the
size and shape of the window for the Remote Console, no matter how this
window is resized by the Remote-side user.
Figure 37: Remote Console Options Menu: Scaling
Mouse Handling
The submenu for mouse handling offers two options for synchronizing the local and the
remote mouse cursors.
Page 52
52
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.
Local Cursor
This submenu offers a list of different cursor shapes for the mouse pointer visible by the
Remote user. 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 pointer shapes
depends on the version of the Java Virtual Machine installed on the Remote computer;
version 1.5 or above will offer the full list.
Figure 38: Remote Console Options Menu
Video Settings
This submenu opens a panel for changing the CAT5 8-PORT/16-PORT IP-KVM video
settings. The CAT5 8-PORT/16-PORT IP-KVM has two separate areas where different
video settings can be configured. One area is the Remote Console window’s Options
menu, the other area is in the CAT5 8-PORT/16-PORT IP-KVM’s web interface
configuration menus.

Video Settings via the Remote Console’s “Options > Video Settings”
Figure 39: Video Settings Panel
Brightness - Controls the brightness of the picture
Contrast Red/Green/Blue - Controls the contrast of the picture
Clock - Defines the horizontal frequency for 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 configurations. If the
picture quality still has problems after auto adjustment, you can try to adjust this
setting together and the Phase setting, as mentioned below.
Phase - Defines the phase for video sampling. This is used with the
above-mentioned Clock setting to control the display quality.
Horizontal Position - Defines the horizontal positioning of the video.
Vertical Position - Defines the vertical positioning of the video.
Reset this Mode - Resets video mode-specific settings (Clock , Phase and Position)
to the factory defaults.
Reset all Modes - Reset all settings to the factory defaults.
Save changes - Save changes permanently
Undo Changes - Restore last settings
Video Settings via the Web Management GUI
To set the video feed’s “Noise Filter”, use the CAT5 8-PORT/16-PORT IP-KVM’s web
management GUI. In the left-hand column, click on KVM Settings > Video. This will open
the Miscellaneous Video Settings screen.
The “Noise Filter” option defines how the CAT5 8-PORT/16-PORT IP-KVM reacts to small
changes in the video input signal. Turning on the noise filter can help reduce video
flickering that is often caused by interference, and can help lower unnecessary bandwidth
consumption. A large filter setting needs less network data traffic and enables a faster
Page 54
54
video display, but some small changes in the display may not be recognized immediately.
A small filter setting displays all changes instantly, but may lead to a constant stream of
network traffic, even if the display content is not actually changing (depending on the
quality of the video input signal). In general, the default setting should be suitable for most
situations.
Click the “Force Composite Sync” button if you are using a SUN computer or server on the
Host-side.
After adjusting any settings, click the Apply button to save your changes.
Refresh Video
Click this menu item in the Options menu list of the Remote Console to refresh the video
stream coming from the Host system. Usually, only the parts of the video feed that have
changed will be sent from the CAT5 8-PORT/16-PORT IP-KVM in order to save network
bandwidth. This function is mainly for troubleshooting issues that may occur when old
video fragments are not updated quickly for some reason. One of the reasons for this
could be that the “Noise Filter” setting for video has been set too high. To adjust the
Noise Filter setting, please refer to the previous section.
Soft Keyboard
Figure 40: Soft Keyboard
Click this menu item to open up the submenu for the Soft Keyboard.
Show
Clicking this item brings up the Soft Keyboard. The Soft Keyboard may be necessary
if your Host system runs a completely different language and country mapping than
your Remote computer.
Mapping
This menu item is used for choosing the specific language and country mapping of the Soft Keyboard.
Page 55

55
Figure 41: Soft Keyboard Mapping
Local Keyboard
Used to change the language mapping of your browser machine running the
Remote Console Applet. Normally, the applet determines the correct value
automatically. However, depending on your particular JVM and your browser
settings this is not always possible. A typical example is a German localized system
that uses an US-English keyboard mapping. In this case you have to change the
Local Keyboard setting to the right language, manually.
Hotkeys
This menu item opens a list of pre-defined hotkeys, which is useful for hotkey
combinations that may be difficult to send, such as CTRL+ALT+DEL. Click any entry and
that specific command will be sent to the Host system.
A confirmation dialog will appear before the system sends the selected command to the
Host system. Click the OK button execute the key combination on the Host system.
Figure 42: Remote Console Confirmation Dialog
Encoding
These options are used to adjust the encoding level in terms of compression and
color depth. They are available only when "Transmission Encoding" is determined
manually (select Manually in KVM Settings > User Console > Transmission
Encoding of web page).
Page 56
56
Compression Level
You may select a value between 1 and 9 for the desired compression level 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 to 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 colors 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.
Page 57
--
57
Figure 43: Encoding Compression
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.
Figure 44: Predefined Compression
Page 58
58
Figure 45: Lossy Compression
Color Depth:
Set the desired color depth. You may select between 8 or 16 bit for Video
Optimized/compression level 0, or between 1 and 8 bit for compression level 1 to 9.
The higher the color depth, the more video information has to be captured and to be
transferred.
Page 59
-59-
Figure 46: Encoding Color depth
Note: If displaying motion pictures on a connection with low speed you may
achieve an improvement regarding the video transfer rate by lowering the color
depth and disabling the option "Video Optimized". As a general result, the data
rate is reduced (less bits per color). Furthermore, the CAT5 8-PORT/16-PORT
IP-KVM will not have to do any video compression. In total, this will lead to less
transfer time of the motion picture.

10.3.3 Status Line of Remote Console
Status line
The status bar shows the status of the Remote Console as well as the status of the
connection between the Host system and the Remote system. The size of the
remote screen is displayed. Figure below was taken from a Remote Console with
a resolution of 1024x768 pixels. The value in brackets describes the connection to
the Remote Console. “Norm” means a standard connection without encryption;
“SSL” means a secure connection.
Figure 47: Status line
The right-hand side of the Status Bar may show the frame rate of the video in
frames per second (Fps), and the current incoming (In) and outgoing (Out)
transmission rates. If compressed encoding is enabled, the compressed transfer
rate will be displayed in bracket

11.1 Remote Control
The Remote Console is the redirected screen, keyboard and mouse of the remote host
system that CAT5 8-PORT/16-PORT IP-KVM controls. The Remote Console window is a
Java Applet that tries to establish its own TCP connection to the CAT5 8-PORT/16-PORT
IP-KVM.
Starting the Remote Console opens a new window displays screen movement of host
system, with its size automatically adjusted to optimum. Keyboard and mouse are
redirected to control the host system simultaneously. A slight delay may present
depending on the bandwidth of network.

To open the KVM console either click on the icon Console or Remote Control >
KVM Console of the menu entry on the left or Click to open of the console picture
on the right.
11.1.2 Telnet Console/SSH Console
In general, the Telnet or SSH 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 is activated (if the serial settings were configured
accordingly). All inputs and outputs are redirected to the device via the serial
port, and its answers are displayed on the Telnet interface.
In order to log in with Telnet or SSH, you have to enable the access settings
from
Device Settings > Network.
Page 63
-63-
Telnet Console
The CAT5 8-PORT/16-PORT IP-KVM firmware features a Telnet server that
enables a user to connect via a standard Telnet client. In case the Telnet program is
using a VT 100, VT 102 or VT 220 terminal or an according emulation, it is even
possible to perform a console redirection as long as the CAT5 8-PORT/16-PORT
IP-KVM host machine is using a text mode screen resolution.
To log in Telnet Console by one of the following way:
1. clicking Remote Control > telnet Console
Figure 50: Telnet Console
Page 64
-64-
2. or telnet command as required by the Telnet client, for instance in a UNIX shell:
telnet 192.168.0.70
3. or run the SSH-supported terminal emulation program (such as PuTTY).
Replace the IP address by the one that is actually assigned to the CAT5
8-PORT/16-PORT IP-KVM. This will prompt for 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 according functions of the web
interface.
Once you have successfully logged into the CAT5 8-PORT/16-PORT IP-KVM a
command line will be presented and you can enter according management
commands.

Contrast).
SSH Console
The CAT5 8-PORT/16-PORT IP-KVM supports the SSH security protocol. The
device uses version 2 of the SSH protocol (SSH2) to encrypt the transferred data
and secure transmissions. The SSH configuration interface is the same as that of
Telnet, except for the fact that SSH is encrypted and therefore more secure.
Please run the SSH-supported terminal emulation program (such as PuTTY).

11.1.3 Remote Wakeup
The CAT5 8-PORT/16-PORT IP-KVM provides the remote power wakeup function,
which can remotely wake up the sleeping computer. With this feature, the computers that
are not in use for now can be shut down and remotely wake up the computer when want
to use it, and thus save the power energy.
Settings on target computer:
To wake up a remotely located computer via the CAT5 8-PORT/16-PORT IP-KVM,
some settings have to be pre-configured on the target computer:
1. BIOS setting:
Enable the wakeup function in the BIOS of the target system.
Note: The naming of the wakeup function in BIOS varies depending on the type of
BIOS. It may be listed as Wake On LAN/PME, PME Event Wake Up, or Power
On By PCI Device.
2. Windows Settings:

11.2 Virtual Media
The CAT5 8-PORT/16-PORT IP-KVM provides a powerful feature called Virtual Media
(or Virtual Disk). The CAT5 8-PORT/16-PORT IP-KVM can present either a local floppy
disk image (stored on the CAT5 8-PORT/16-PORT IP-KVM) or a redirected remote
CD/DVD-ROM image (redirected from the Remote computer) to the target computer
through the built-in USB port. This can allow for system recovery in conditions including
disk failure or no primary network connection on the target computer.
Drive Redirection allows you to share (redirect) your local drive (floppy drives, hard disks,
CD ROMs and other removable devices like USB sticks) with the remote system over a
TCP network connection. Thus, with Drive Redirection, you can use a virtual disk drive
on the remote computer instead of an image file. It is also possible to enable a remote
machine to write data to your local disk.
Before go ahead with this setup, both remote user computer and local computer (the one
connected with the CAT5 8-PORT/16-PORT IP-KVM unit) would have to have Operating
System Win2000, XP or above. This function would not work on other platforms at this
moment.
Before using Virtual Media, please connect the USB cable from CAT5 8-PORT/16-PORT
IP-KVM to host computer. After connecting the USB cable, you can see a “Removable
Disk” on the host computer. Below is the host computer screen (the computer which
connected with CAT5 8-PORT/16-PORT IP-KVM).

11.2.1 Drive Redirection
The Drive Redirection function gives the administrator another virtual disk drive on the
Host computer. With Drive Redirection, you do not have to use an image file. Instead, the
Remote-side user can open a drive on his or her local computer and use it on the Host
machine. Thus, the drive is shared over a TCP network connection. Devices that can be
redirected are floppy drives, hard disks, CD-ROM drives, and other removable devices
such as USB storage drives.
Figure 51: Options of Drive Redirection
It is even possible to enable write support so that the Remote-side user can write data to
his or her local disk from the Host machine. However, if write support is enabled, care
should be taken that the two systems do not write onto the same disk at the same time, as
computer operating systems cannot distinguish a local system from a redirected system.
WARNING: If both the Host system and the Remote system try to write data on the
same device at the same time, data may be damaged and/or lost. Please use this
feature only if you know what you are doing.
Page 71
-71-
Please be noted that Drive Redirection works on a more basic level than the operating
systems of the computers. This means that neither the Remote-side nor the Host-side
operating system is aware that the drive is being redirected. This may lead to inconsistent
data when the operating system (either on the Remote-side or Host-side machine) is
writing data on the device. If write support is enabled, the Host computer might damage
the data and the file system on the redirected device. On the other hand, if the
Remote-side operating system tries to write data to the redirected device, the drive cache
of the Host’s operating system might contain older data.
Because the operating systems are not aware that the drive is being redirected, they could
try to write data at the same time and therefore cause error messages to pop up. We
therefore recommend that the Remote user uses the Drive Redirection function with care,
especially if write support is enabled.
Disable Drive Redirection
To disable the Drive Redirection function.
Force read-only connections
If you enable the Force read-only connections function, write support for the Drive
Redirection feature will be switched off once you click Apply. This will make it
impossible to write on a redirected device, which is a safer option if you don’t want to
take the risk of file-system-destroying write-over collisions between the Remote and.

11.2.2 Virtual Drive
Figure 52: USB mass storage option
Enable this option to disable the mass storage emulation (and hide the virtual drive) if you
are not presenting (or “mounting”) a disk image file or drive to the Host system. After
ticking or unticking the checkbox, click the Apply button to save your changes.
Note: If the above setting is not enabled, and if no disk image file is detected, the Host
Page 72
-72-
system could possibly hang in boot mode due to changes in the boot order or the boot
manager (LILO, GRUB). Such incidents were reported for some Windows versions
(Windows 2000 and Windows XP), and other operating systems might behave in the same
way. The actual OS behavior will depend on the BIOS version used in the specific
machine.

11.2.3 CD/DVD Image
Use Image on Windows Share (via SAMBA)
To include an image from a Windows share, select “CD/DVD Image” from the submenu.
Figure 53: Virtual Media - CD-ROM Image
Share host
Enter the server name or its IP address (the computer/server that shares out the
image file).
Note: For Windows 95, 98 and Windows ME, do not enter the IP address; enter the
server name (e.g. “NetBIOS Name”).
Share folder name
Enter the name of the relevant share folder.
Image file name
Enter the name of the image file as it is on the share folder.
User (optional)
If necessary, specify the username for the share named before. If unspecified and a guest account is activated, this guest account information will be used as your login.
Password (optional)
If necessary, specify the password for the given user name.
Page 74
-74-
Notes:
1. The output image extension file must be an ISO image file, and the file name
extension must be ‘iso’, e.g. CD-Rom_vir.iso.
2. You can create an ISO file up to 650 MB in size (CD-ROM size). This drive will be
accessible only in read-only mode, you will not be able to write any information to it.
This drive can act as a boot drive if the motherboard/BIOS on the Host computer
supports the USB BOOTABLE function. For emulating a DVD Drive, please use Drive
Redirection function.
3. The information required for the steps above has to be given from the point of view of
the CAT5 8-PORT/16-PORT IP-KVM. Please enter IP addresses and device names
accordingly. Administrative permission is required for this, as regular users may not
have access rights. Please log in as a system administrator (or as “root” on UNIX
systems). It is also important to specify the correct IP-KVM IP addresses and device
names. Otherwise, the CAT5 8-PORT/16-PORT IP-KVM may not be able to access
the referenced image file properly. This will cause the CAT5 8-PORT/16-PORT
IP-KVM to leave the given file unmounted, and instead display an error message.
4. The specified share has to be configured correctly. Administrative permission is
required for this. Normal user may not have a high enough level of authorization. You
should either login in as a system administrator (or as “root” on UNIX systems), or ask
your system administrator for help to complete this task.
Page 75
-75-
Operation Procedures:
1. Please run Nero or any CD/DVD imaging tool to create CD/DVD ISO image.
2. Please create a folder and share this folder on the PC that shares out the image file.
Copy the CD/DVD ISO image file to this sharing folder. (Please make sure password
has to be setup with the authorized user during Sharing => Permission settings)
MS Windows
Open the Explorer, navigate to the directory (or share) and press the right mouse button
to open the context menu. Select Sharing to open the configuration dialog
Figure 54: Explorer Context Menu

Figure 55: Share Configuration Dialog
Adjust the settings for the selected directory.
Activate the selected directory as a share. Select Share this folder.
Choose an appropriate name for the share. You may also add a short
description for this folder (input field Comment).
If necessary, adjust the permissions (Permissions button).
Click OK to set the options for this share.
UNIX and UNIX-like OS (UNIX, Solaris, Linux)
If you like to access the share via SAMBA, SAMBA has to 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.
Viewing the man-entry of smb.conf may also provide additional help.
Page 77

11.2.4 Floppy Disk
Figure 56: Virtual Media - Floppy Disk
The maximum image size is limited to 1.44MB. To use a larger image, mount this image via
Windows Share (or SAMBA) (see the Section called Use Image on Windows Share (via SAMBA)
for details)
Operation Procedures:
1. You need to create the floppy image file first (Please refer to the section “Creating
a floppy image”). For this example, we used Raw Write program (or any other
image-creator software) to create the floppy image. Please use licensed software
for this purpose.
2. You can find an image file saved at desire destination after you created it with Raw
Write.
3. Open the browser to log into the CAT5 8-PORT/16-PORT IP-KVM. Click Virtual
Media > Floppy Disk. Click
the Browse button to choose the image file.
Click on the button Upload to initiate the transfer of the chosen image file into the CAT5
Page 79
-79-
8-PORT/16-PORT IP-KVM module’s on-board memory
4. After you uploading the image file, you will see the information below.
5. Open the remote console and you will see a virtual Floppy drive is created on the
host computer that connected to CAT5 8-PORT/16-PORT IP-KVM.
The maximum size of the floppy image disk is 1.44MB. This drive is in read-only mode and
does not allow you to write any information on the drive. This drive can act as a boot drive
if the motherboard/BIOS on the Host computer supports the USB BOOTABLE function.
Notes:
1. For any image-creating software, the output image’s file extension must be “.img”, e.g.
“floppy_vir.img”.
2. The uploaded image file will be kept in the onboard memory of the CAT5
8-PORT/16-PORT IP-KVM until the end of the current session. A session ends when
you log out or initiate a reboot of the CAT5 8-PORT/16-PORT IP-KVM.

11.2.5 Creating an Image
11.2.5.1. Creating a Floppy Image
MS Windows
You can use the tool “Raw Write for Windows”. You can get the RawWrite software from
the website http://www.chrysocome.net/rawwrite.
Figure 57: Raw Write for Windows selection dialog
From the menu, select the tab “Read”. Enter (or choose) the name of the file in which you
would like to save the floppy content. Click on the button “Read” to initiate the image
creation process.
UNIX and UNIX-like OS
To create an image file, you can use the “dd” command. 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 disk 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.).
Page 81
-81-
11.2.5.2. Creating a CD/DVD ISO Image
MS Windows
To create the image file, use your favorite CD imaging tool. Copy the whole contents of the
disk into one single image file on your hard disk.
For example, with “Nero” you should select “Copy and Backup”. Then, click on 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.
Figure 58: Nero selection dialog
UNIX and UNIX-like OS
To create an image file, you can use “dd” command. This is one of the original UNIX
utilities and is included in every UNIX-like OS (UNIX, Sun Solaris, and Linux).
To create a CD-ROM 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.).

11.2.6 Making a Drive Redirection
The operation for making a Drive Redirection as below:
1. Click Remote Control > KVM Console.
2. Click on the “Floppy” icon
You will see the Driver Redirection window as below
Figure 59: Built-in Java Drive Redirection
3. You can either redirect a local drive (only available under Windows) or redirect an ISO
CD/DVD image.
Page 83
-83-
3a. If you click the Connect Drive button in the Drive Redirection field, the following issues
need to be taken into consideration:
Select the drive to be redirected and click OK.
Select the drive that should be redirected. All available devices (drive letters) are
shown here. Please be noted that the entire hard disk that the drive belongs to will be
shared with the Remote computer, not only one partition. If you have a hard disk with
more than one partition, all partitions that belong to this disk will be redirected. The
“Refresh” button can be used to regenerate the list of drive initials. This is especially
handy when working with a USB stick.
Write Support
This feature may be enabled here. Write support means that the remote computer is
allowed to write on your local drive. As you can imagine, this is very dangerous. If both
the remote and the local system try to write data on the same device, this will certainly
destroy the file system on the drive. Please use this feature only if you exactly know
what you are doing.
Warning
Please be cautious that if “Allow Write Support” is
selected, all data on the shred media might be destroyed.
Warning
1. Drive Redirection is only possible with Windows 2000 or later versions.
2. The Drive Redirection works on a low SCSI level and the SCSI protocol
cannot recognize partitions; therefore the whole drive selected will be shared
instead of any particular partition.
Page 84
-84-
3b. If click on Connect ISO
Select the ISO image file and click Open
4. Finally the established Drive Redirection connection will be displayed
Open My Computer you will see the virtual drive appears on the remote host PC window.
Page 85
-85-
The drive redirection software will try to lock the Remote-side local drive before it is
redirected. That means that it will try to prevent the local operating system from accessing
the drive as long as it is redirected. This attempt may fail, especially if a file on the drive is
open when the attempt is made. In the case of such a locking failure, you will be prompted
if you want to establish the connection anyway. If Write Support is enabled, a drive which
is not locked may be damaged by the Drive Redirection. This should not be a serious
problem if the Write Support is disabled.
Clicking on the Disconnect button will disconnect the Drive Redirection connection.
Please note that the Virtual Drive is created on the “device level”, not the “partition level”,
which means that the computer looks for I/O at the BIOS level and sends the
corresponding data to the Host computer. This means that it sends the entire hard drive
(which may consist of multiple partitions) and emulates all of those partitions on the Host
computer. A DVD drive can be emulated in the same way. However, such a “virtual” DVD
drive cannot act as a boot drive like floppy and CD-ROM images can.

11.3 User Management
On an CAT5 8-PORT/16-PORT IP-KVM, each username has permission levels that are
assigned to it. These permission settings affect how the user interfaces with the Remote
Console. Permissions allow or forbid the user from performing various actions on the CAT5
8-PORT/16-PORT IP-KVM’s web pages. There are three permission“ranks” that can be
assigned to any user at any time by any user that has the relevant permission “rank”. The
highest permission rank is “super user”, then “administrator”, then “user” at the bottom of
the rank hierarchy.
11.3.1 Change Password
Figure 60: Setting Password
Click on User Management > Change Password to change the password for the
currently logged in user account. Enter the relevant old and new passwords, and
then click the Apply button to save your changes.
Page 87
-87-
11.3.2 Users and Groups
Figure 61: Users and Groups
There are three permission levels of user accounts:
Super -- Has permission to change all configurations and use all functions.
Administrator -- Has permission to change most configurations and use most functions
User -- Has permission to access only the basic functions of the Remote Console
You can choose the desired level from the selection box role.
The CAT5 8-PORT/16-PORT IP-KVM comes pre-configured with a factory default
“super user” account that is permitted to make all possible configuration changes and
use all the device’s functions.
The factory default username and password for this super user is “super” and
“pass”. Make sure you change the password immediately after you have
installed your CAT5 8-PORT/16-PORT IP-KVM.
Existing users
Select an existing user for modification. Once a user has been selected, click
the Lookup button to display the user’s information.
New User name
Enter a name for the new user account.
Password
Enter a password for the selected user. It must be at least three characters long.
Confirm password
Re-enter the password for the selected user for confirmation.
Page 88
-88-
Email address
Enter the user’s e-mail address here. (optional)
Mobile number
Enter the user’s mobile phone number here. (optional)
Role
Assign a permission level, or role, to the selected user.
To create an user press the button Create. The Modify button changes the displayed
user settings. To delete a user press the button Delete.
Note: The CAT5 8-PORT/16-PORT IP-KVM is equipped with a built-in processor and
memory unit, which both have limitations in terms of the processing instructions and
memory space. To guarantee an acceptable response time, we recommend that you do
not let more than 15 users connect to the CAT5 8-PORT/16-PORT IP-KVM at the same
time. The memory space available on the CAT5 8-PORT/16-PORT IP-KVM mainly
depends on the configuration and usage of the CAT5 8-PORT/16-PORT IP-KVM (log file
entries, etc.). For this reason, we recommend that you do not store more than 63 user
profiles.
11.4 KVM Settings
Page 89
-89-
11.4.1 User Console
The following settings are user specific. That means, the super user can customize these settings for every user separately. Changing the settings for one user does not affect the settings for the other users
Figure 62: User Console Setting
Page 90
-90-
Remote Console Settings for User (user select box)
This selection box displays the username whose configuration values are displayed
and for which any changes will take effect. You may change the settings of other
users if you have the required permission level. Use the dropdown box to select the
user whose configuration settings you want change, then click the Update button.
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 processing depending on the
number of users logged in at the same time and the network 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
Use the dropdown box to select the network speed that most closely matches the
CAT5 8-PORT/16-PORT IP-KVM’s connection speed to automatically choose the
best settings for compression and color depth for the indicated network speed.
Manually
This field lets you adjust both the compression rate and the color depth
individually. Depending on the selected compression rate, the data stream
between the CAT5 8-PORT/16-PORT IP-KVM and the Remote Console will be
compressed in order to save bandwidth. Since high compression rates use more
of the CAT5 8-PORT/16-PORT IP-KVM’s computing power, they should not be
used while several users are accessing the CAT5 8-PORT/16-PORT IP-KVM
simultaneously.
The standard color depth is 16 -bit (65536 colors). Other color depths are intended
for slower network connections in order to allow for faster transmission of data.
Compression level 0 (no compression) uses only 16-bit color. For low bandwidth
connections, 4-bit (16 colors) and 2-bit (4-color grayscale) are recommended for
typical desktop interfaces. To retain a high-quality image on a low bandwidth
connection, such as when viewing photos, try 4-bit (16-color grayscale). 1-bit color
depth (black/white) should only be used for extremely slow network connections.
Remote Console Type
This field specifies which Remote Console viewer the selected user will use.
Default Java-VM
This viewer uses the default Java Virtual Machine (JVM) of your Browser. This
may be the Microsoft JVM for Internet Explorer, or the Sun JVM if the browser is
configured to use it by default. Use of the Sun JVM may also be forced manually
Page 91
-91-
(see below).
Sun Microsystems Java Browser Plugin
This viewer instructs the web browser that your GUI is running on to use the Sun
Microsystems Java Virtual Machine (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 if 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 instruct your browser to download and install the plugin,
usually through prompts that will appear, and an 11 MB plugin will need to be
downloaded. (The CAT5 8-PORT/16-PORT IP-KVM will provide a link to the JVM
plugin if the Remote computer does not already have it installed. The user could
also install the latest Java software later, if needed.)
The advantage of downloading Sun's JVM is that it provides a stable and identical
experience across different platforms. The Remote Console software is optimized
for this JVM version and offers a wider range of functionality when run in Sun's
JVM. Please make sure that you install Sun JVM 1.5 or above in your client
system.
Miscellaneous Remote Console Settings
Start in Monitor Mode
This setting sets the initial value for the Monitor Only mode. By default, Monitor Only
mode is off. If you enable this setting, the Remote Console window will open in
view-only mode.
Start in Exclusive Access Mode
If you enable this setting, the Remote Console will start in Exclusive Access mode.
This means that the Remote Console windows of all other users will be forced to
close if this user opens the Remote Console for the CAT5 8-PORT/16-PORT IP-KVM
on his or her computer. No one else can open the CAT5 8-PORT/16-PORT IP-KVM’s
Remote Console window until this user disables Exclusive Access mode or logs off..
Mouse hotkey
This lets you specify a hotkey combination for this user that will either start the mouse
synchronization process when Double Mouse Mode is active, or will free the mouse
pointer from being captured by the Remote Console when Single Mouse Mode is
active.
Remote Console Button Keys
Button Keys allow keystroke combinations to be sent to the Host computer that
normally cannot be generated on the Remote computer. The reason for this might be
a missing key, or the fact that the local operating system of the Remote computer is
Page 92
-92-
unconditionally catching this key combination already. Typical examples are
“Control+Alt+Delete” in Windows and DOS, or “Control+Alt+Backspace” on Unix or
Unix-like operating systems for restarting X-Server.
The syntax to define a new Button Key is as follows:
[confirm] <keycode>[+|-[*]<keycode>]*
“confirm” programs the system to display a confirmation dialog box (Yes/No) before a
keystroke sequence is sent to the remote host.
“keycode” is the key sequence that will be sent. Multiple key codes can be
concatenated with a plus or a minus sign. The plus sign builds key combinations
where all keys listed will be pressed until a minus sign or the end of the combination
is encountered, where all pressed keys will be released in reversed sequence. The
minus sign builds single, separate key presses and releases. The star(*) inserts a
pause with duration of 100 milliseconds.
Page 93
-93-
11.4.2 Keyboard/Mouse
Figure 63: Keyboard and Mouse Settings
Keyboard Model
Select the keyboard configuration that matches the one that will be used by the
Remote user. This will help ensure that keystrokes received by the Host
computer match the ones sent by the Remote computer. 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.
Keyboard timeout
We recommend that you enable this setting if the Host system runs on a UNIX or
UNIX-like OS.
Mouse Speed
• Auto mouse speed
Use this option if the mouse settings on the Host system use an additional
acceleration setting. The CAT5 8-PORT/16-PORT IP-KVM tries to detect the
acceleration and speed of the mouse during the mouse sync process.
• Fixed mouse speed
This option uses a direct translation of mouse movements between the local and
the remote pointer. You may also adjust the fixed scaling which determines
number of pixels to move the remote mouse pointer when the local mouse
pointer is moved one pixel. This option is used to manually control the remote
Page 94
-94-
mouse speed and only works when the mouse settings on the host are linear.
This means that any mouse acceleration settings of the OS should be disabled.
Also, the Remote Console’s Intelligent Sync function will not be available when
fixed scaling is selected.
• Absolute mouse scaling for MAC server
Enable this option if the Host computer uses Mac OS.
After making any changes, click the Apply button to save your settings.
11.4.3 Video
Figure 64: Video Settings
Miscellaneous Video Settings
Noise filter
This option defines how the CAT5 8-PORT/16-PORT IP-KVM reacts to small
changes in the video input signal. Turning on the noise filter can help reduce
video flickering that is often caused by interference, and can help lower
unnecessary bandwidth consumption. A large filter setting needs less network
data traffic and enables a faster video display, but some small changes in the
display may not be recognized immediately. A small filter setting displays all
changes instantly, but may lead to a constant stream of network traffic, even if
the display content is not actually changing (depending on the quality of the
video input signal). In general, the default setting should be suitable for most
situations.
Force Composite Sync (Required for Sun Computers)
When connecting the device directly to a legacy Sun computer that uses
composite sync as the video output, the CAT5 8-PORT/16-PORT IP-KVM may
not recognize the composite sync video output automatically. To support signal
transmission from a Sun machine, enable this option. If this is not enabled, the
video feed of the Remote Console may not be visible.

IP auto configuration
With this option you can control whether the CAT5 8-PORT/16-PORT IP-KVM
should fetch 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 and you will need to set a static IP.
Warning
Changing the network settings of the 8-PORT/16-PORT IP-KVM might result in losing
your connection to it. In case you change the settings remotely make sure that all the
values are correct and that you still have a way to access the 8-PORT/16-PORT IP-KVM
if the connection is lost, such as though a local network.

the CAT5 8-PORT/16-PORT IP-KVM needs to be accessible from networks
other than the local one, this IP address must be set to the local network router's
IP address.
Primary DNS Server IP Address
Here you can set the primary DNS server for the CAT5 8-PORT/16-PORT
IP-KVM. This option may be left blank, but the CAT5 8-PORT/16-PORT
IP-KVM will then be unable to perform name resolution.
Secondary DNS Server IP Address
Here you can set the secondary DNS server for the CAT5 8-PORT/16-PORT
IP-KVM. It will be used in case the Primary DNS Server cannot be contacted.
Remote Console And HTTPS port
Here you can set the port the CAT5 8-PORT/16-PORT IP-KVM will use for
the Remote Console server and HTTPS server. If this is blank, the default
port of 443 will be used.
HTTP port
Here you can set the port the CAT5 8-PORT/16-PORT IP-KVM will use for the
HTTP server. If this is blank, the default port of 80 will be used.
Telnet port
Here you can set the port the CAT5 8-PORT/16-PORT IP-KVM will use for the
Telnet server. If this is blank, the default port of 23 will be used.

This enables the SSH (Secure Shell) function.
Disable Setup Protocol
Enable this option to exclude the CAT5 8-PORT/16-PORT IP-KVM from the setup
protocol. Setup protocol is a proprietary layer-2 MAC-based protocol to allow
some configuration software to detect CAT5 8-PORT/16-PORT IP-KVM devices
in the network, even without IP address, and then configure network related
settings for the CAT5 8-PORT/16-PORT IP-KVM.
11.5.2 Dynamic DNS
Figure 66: Dynamic DNS

Dynamic DNS allows you to use a Dynamic DNS service to reach your CAT5
8-PORT/16-PORT IP-KVM by an easy to remember domain name rather than by its
IP address. This can also be useful if your IP address changes frequently, such as
when using a DSL connection. When Dynamic DNS is enabled, the CAT5
8-PORT/16-PORT IP-KVM will connect to a DDNS service at regular intervals to
update it with its current IP address. The Remote user can then simply open a web
browser to go to the easy to remember address (e.g. mykvm.dyndns.org) provided by
the DDNS service. There are many freely available DDNS services available, such as
www.dyndns.org, which is used in the example diagram below.
Figure 67: Dynamic DNS Scenario
You have to perform the following steps in order to enable Dynamic DNS:
• Make sure that the LAN interface of the CAT5 8-PORT/16-PORT IP-KVM is properly
configured.
• Create an account with a DDNS service provider and set up a hostname for the CAT5
8-PORT/16-PORT IP-KVM to use. You will need the username and password for your
DDNS account as well as the hostname you will use.
• Enable Dynamic DNS and enter the required settings, as described below. After making
your changes, click the Apply button to save your changes.
Enable Dynamic DNS
This enables the Dynamic DNS service. This requires you to have configured a DNS
server’s IP address.
Dynamic DNS server
This is the address of the DDNS service the CAT5 8-PORT/16-PORT IP-KVM will
use. Currently, this is a fixed setting as only dyndns.org is currently supported.
DNS System
Choose Dynamic for free DNS service. Customize this for your own domain.
Hostname
Enter the hostname of the CAT5 8-PORT/16-PORT IP-KVM that is provided by the
Page 100
-100-
Dynamic DNS service. Make sure you enter the entire hostname, including the
domain. (e.g. testserver.dyndns.org)
Username
Enter the username for your DDNS service account. The username may not contain
any spaces.
Password
Enter the password for your DDNS service account.
Check time
The CAT5 8-PORT/16-PORT IP-KVM registers itself for initiating the IP address of
CAT5 8-PORT/16-PORT IP-KVM stored in the Dynamic DNS server at this time.
Check interval
This is the interval for reporting again to the Dynamic DNS server for updating the
IP address associated with the Domain Name of the CAT5 8-PORT/16-PORT
IP-KVM.
Warning
The CAT5 8-PORT/16-PORT IP-KVM has its own independent real time clock.
Make sure the time setting of the CAT5 8-PORT/16-PORT IP-KVM is correct.
