3.3. Configuring the Attached Computer/Server for Better Performance
There are several aspects that have to be taken into consideration when configuring your
computer/ server for the best performance:
Refrain from selecting too peculiar video resolution modes. Choose a resolution that is within
KLEv3's standard support.
Turn off special transition effects on your operating system such as fade.
Adjust the server desktop background with preferably plain solid colors with simple designs.
Concerning digital DVI video, KLEv3 is able to capture any resolution up to 2048x1152@60Hz.
The video resolution is discovered automatically.
Concerning analog VGA video, not all resolutions are possible. The video resolution discovery is
made by comparison with an internal table of VESA standards. Please refer to the table of
supported VGA video resolutions.
Please note that RB means reduced blanking. Resolutions with RB are not intended for older
CRT monitors. They are newer VESA standards for digital devices, which precisely KLEv3 is.
However, not all computers can generate reduced blanking VGA video.
In a general way, you will get much better results by using digital video: better video quality,
better video speed, higher compression, faster mouse, etc. Use HDMI or DVI each time
possible.

3.4. Default Settings
The factory default network settings for KLEv3 are as follows:
IPv4 Address: 192.168.1.200
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.254
DNS Servers: 192.168.1.254
Default access to KLEv3 Web Management Interface:
ht tps://192.168.1.200:5908
Figure 3: Welcome to KLEv3 Management
Default administrator account name and password:
User name: superuser
Password: superu
3.5. First Access to the Web Management
The first access to the KLEv3 HTTP server can be a little bit tricky if the default settings of KLEv3,
i.e., HTTPS://192.168.1.200:5908 are not compatible with your LAN, or if another machine
already occupies this address. In this case preferably use KCenter or getipdev
(http://www.prosum.net/download/GETIPDEVInstall.exe) to give a temporary IP address to
KLEv3. Then open the KLEv3 web management to confirm this IP address or to change the IP
settings.
* You could also create an isolated network, not connected to the local or company network, between KLEv3 and a
computer with a simple cross connect cable. Then set up the IP address of the computer to something like 192.168.1.xxx
, and then with a browser, open KLEv3 management at default address HTTPS://192.168.1.200:5908
*When accessing to the KLEv3 Web Management, your browser may provide a security warning. Please choose
"Continue to this website" since there is no risk of pirate website here. These warnings are not relevant for HTTPS
servers of hardware devices such as KLEv3. You can also install the Root certificate of KLEv3 in the list of trusted CA if
you want to remove this warning. You will also have to authorize the usage of certificates that do not contain the
name of the HTTPS server.

3.6. Setting Up the Network Interfaces
Using a browser, login to the KLEv3 Web Management. Expand Main on the left menu and click
Networks.
Figure 4: Network Settings
Specify the port base for viewer connections in TCP Port Base. You can choose any available
port base, starting from 5900 with an increment of 10 right up to 6400. TCP port base + 8 is the
port number you will use for https web management.
Specify the host name, i.e., the name that KLEv3 will assume on your Local Area Network. Click
Set Default to load the default unique host name composed of the product name and the
hardware MAC address of the Ethernet port.
3.6.1. EthernetIPSettings
The Ethernet 10/100 is the default network interface. It is faster than the Wireless Interface.
Fill in the form. Please refer to the help page if you need more information.
3.6.2. WirelessInterfaceIPSettings
This subsection is hidden if you do not have a compatible wireless 802.11 USB adapter plugged
in the USB extension port of your KLEv3. The supported USB adapter is the EW-7811 from
Edimax.
Figure 5: Wireless 802.11 USB Adapter

KLEv3 User Manual V1.0

Preferably use a WPA/WPA2 wireless connection. Older protocols such as WEP are unsecure.
Check Enable Wireless Interface to put the wireless interface in service. Wait until the service is
started and the wireless part of this form is displayed.
In Network Name (SSID), select the name of the wireless network (SSID) you want to connect
to. If you do not know, please get this information from your network administrator. If the
wanted SSID does not appear in the list, try to click on Scan. Eventually, if you cannot get the
desired SSID, this is likely because the access point is out of reach.
Please refer to the help page to fill in the wireless interface parameters. We recommend you
leave the wireless router or access point configure the KLEv3 by checking Use DHCP
3.6.3. StoreSettings
Click the Store Settings button to save the new network setting. Then press the Soft Restart to
put them in service. Once it restarted, all accesses to KLEv3 will need to use the new network
information. The new KLEv3 Web Management address will be:
https://<IP_address>:<TCP Port Base + 8>
For example let's suppose that KLEv3 new IP Address is 192.168.1.192 and that TCP Port Base is
set to 5920, then the KLEv3 Web Management new URL is: https://192.168.1.192:5928
3.6.4. ImportantNote
The Ethernet port and the Wireless port can work simultaneously at the condition they belong
to different IP networks. In the case that both ports are set to conflicting IP addresses, the
Ethernet port will work, and the wireless port will not work whether or not the Ethernet cable
is connected.
So, if you plan you use the wireless alone, i.e., without Ethernet cable, please give to the
Ethernet port a fake IP address in a different network. For example, if the IP address of the
wireless port belongs to 192.168.1.xxx, you could set the Ethernet Port to 192.168.2.xxx
(netmask = 255.255.255.0).
*Make sure you pass all information about KLEv3 to your Network Administrator so that he can make the needed
adjustments to the firewalls, network configuration, and DMZ of routers for the KLEv3 to function properly and to
allow it to be accessed from remote locations across the Internet.

3.7. Downloading the Viewers
There are two different program called viewers for accessing the KLEv3 KVM server. The KVM
server captures and sends the video of the attached computer. In the other direction it receives the
events of your keyboard and mouse and transmits them to the attached computer by simulating an
USB keyboard and mouse.
Both viewers can be downloaded from the KLEv3 Web Management Download --> Viewers. You
have the choice between the Windows viewer and the OS-independent Java viewer. Note that
the Java viewer runs on Windows as well.

file be save at a convenient location. Run or double click the jar file and it will pop up the
Connection Dialog similar to the Windows viewer.
3.8.3. Title Bar Information
The application title bar provides some basic information for your reference. These data are
important for the technician when requested. Changing these basic setting will be further
introduce later on in the manual. Will use below example title as a reference.
SvrName - The name given to the current video server
CompName - The name given to the connected computer
33 ms - The time it takes to capture the image
0 ms - The time used to transmit the video refresh
shared - Currently session set mode
256-bit encryption - Currently used encryption mode
The same information can be found in the applet under the
Information Menu --> Connection Information
The below information is KLEv3 server, with unnamed computer, 46 ms to capture, 2 ms to
refresh, under shared mode, with 256-bit encryption.
Note: The video can be slow when connecting across the Internet. The image quality is
depending on the global bandwidth of the network. Choose the appropriate
compression mode in the viewer connection options (Slow Internet) and if not enough,
use 7-bit video depth. With the maximum compression and 7-bit video quality, it is
possible to work with bandwidths as low as 100 Kbps. Operation

4. Web Management Interface
The Web Management Interface is the main administrative user interface for KLEv3. We already
described several parts of the web management in previous chapter.
This manual will NOT provide detailed information about all web pages of the management. You
can get detailed and up to date information by clicking on Help in each page of the web
management.
Use a modern web browser to access the web management at URL:
https://<IP_address>:<TCP Port Base + 8>
By default this is https://192.168.1.200:5908
Default administrator account name and password:
User name: superuser
Password: superu
When you login to KLEv3 Web Management, your browser may provide a security warning. Click
"Continue to this site (not recommended)". The browser displays this warning because it does not
know the issuer of the KLEv3 certificate. This does not mean that it is less secure than a certificate
provided by an official certification authority. The browser cannot trust this certificate but you can
because you know what you are doing.

5. Viewers
This chapter provides some information, tricks and tips about the Windows and Java viewers.
The Android viewer is not described here but its features are very similar and it provides a
detailed help. The three viewers provide similar performances.
Refer to section 3.8 to login to the Windows or Java Viewer.
5.1. Viewer Menu
This menu provides some information concerning the remote KLEv3 and the video capture:
Name of IP KVM, computer name, screen capture time, screen transmission time, type of
connection (shared, view only), encryption type.
To get the menu-bar back in full-screen or disable-menu-bar mode, place the mouse cursor on
the viewer windows top title bar, right click to get the mouse menu and click on "Show Menu

shortcuts and it will be sent to the remote system.
-Refresh screen: Force the update of the viewer screen.
-Send Cntl-Alt-Del: This is a hard-coded shortcut. When pressing these keys while viewing a
remote system, you would only reboot the local computer because this event is intercepted by
the local system. Click this menu to send these keys to the remote computer.
-Power off current computer: This command requires administrator privileges and a power control
unit connected to operate. It will power down the attached port.
-Power on current computer: This command needs administrator privilege and Power Control Unit
attached for its function. It will power up the attached port.
-New Connection (Win): Open another Connection Dialog to login to another remote server.
-Disconnect: Release access to the remote system. It will also automatically close the viewer
screen.
5.1.2. Settings

Compression
This setting is used to balance the video quality against the data volume. Higher video quality
generates greater data volumes, which should be reserved for good performance networks. We can
sort the settings from the lowest to the highest data volumes as following: Restrict to 8-bit Slow
Internet, Slow Internet, Fast Internet, LAN, and No Compression.
-Slow Internet: Video quality optimized for slow Internet.
-Fast Internet: Video quality optimized for fast Internet.
-LAN: Video quality optimized for 100BaseT.
-No Compression: Can be used when the video is the highest priorityandthebandwidthishigh.
-Restricted to 8-bit: Limit the color depth of the video to 8 bits. The screen colors would
normally be different from the actual remote screen.
Local Cursor
There are really two cursors when you are accessing a remote system using a local computer.
The default setting is optimized for most situations since the mouse synchronization is rather
smooth. When the network bandwidth is very low or your setting for the video resolution is
unusual, the mouse synchronization may be off. The choices for the setting are: No Cursor, Dot,
and Normal.
Session
Most of the internet works on the broadcast structure and so does this product. So it is possible
to share the remote access at different location so long as all the location has the viewer access,
username, and password.
-Shared Session: Logged in user will have full access, including keyboard and mouse.
-View Only: Logged in user only have view access.
Display
Scale by: Display a smaller version of the remote screen.
