* Some older computers with USB interface might need to manually enable the USB option in the BIOS settings before
you can use any USB devices. If your USB interface does not work, please check the USB option in the BIOS.
* If you see Windows 95/98/SE or Mac OS and has not yet installed a USB mouse on your computer, there might be an
error message telling you that mouse is not detected and prompting you to decide whether to ignore the same
message in the future, and yet you will find there is no mouse movement to disable this message. So it is suggested
that you should install your USB mouse on your computer first before connecting to this KVM switch.
3.4. Configuring the Attached PC/Server for Better Performance
There are several aspects that have to be taken into consideration when configuring your PC/ server
for the best performance:
Refrain from selecting too peculiar video resolution modes. Choose a resolution that is within KLEv2
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, KLEv2 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 KLEv2 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.

3.5. KLEv2 Default Setting
The factory default network settings for KLEv2 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
The default access KLEv2 Web Browser Management Interface: https://192.168.1.200:5908
The default administrator account name and password:
User name: superuser
Password: superu
3.6. First Access to the Web Management
The first access to the HTTP server can be a little bit tricky if the default settings, 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 set up a temporary IP address. Then
open the KLEv2 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 KLEv2 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 KLEv2 management at default address HTTPS://192.168.1.200:5908
*When accessing to the 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 KLEv2. You can also install the Root certificate of KLEv2 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.

3.7. Setting Up the Network Interfaces
Using a browser, login to the KLEv2 Web Management. Expand Main on the left menu and click
Networks.
Figure 7: 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 KLEv2 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.
Ethernet IP Settings
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.
Wireless Interface IP Settings
This subsection is hidden if you do not have a compatible wireless 802.11 USB adapter plugged in
the USB extension port of your KLEv2. The supported USB adapter is the EW-7811 from Edimax.

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 KLEv2 by checking Use DHCP
Store Settings
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 KLEv2 will need to use the new network
information. The new Web Management address will be:
https://<IP_address>:<TCP Port Base + 8>
For example let's suppose that the new IP Address is 192.168.1.192 and that the TCP Port Base is set
to 5920, then the Web Management new URL is: https://192.168.1.192:5928
Important Note
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 KLEv2 to your Network Administrator so that he can make the needed
adjustments to the firewalls, network configuration, and DMZ of routers for the KLEv2 to function properly and to
allow it to be accessed from remote locations across the Internet.

3.8. Downloading the Viewers
There are three different programs called viewers allowing to access the KVM server of KLEv2. 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 a USB
keyboard and mouse.
Two viewers can be downloaded from the Web Management: Download --> Viewers. You have the
choice between the viewer for Windows® and the OS-independent viewer for Java™. Note that the
viewer for Java runs on Windows as well.
The third viewer for Android™ must be bought on the Google Play Store: PrimaView.
Figure 9 : Downloading the viewers
Download and install the preferred viewer on your computer.
*To run the Java viewer your computer must have a recent Java installed >= 7.

Viewer Title Bar
The viewer title bar provides some basic information about the connection. These data are important
for the technician when requested. Changing the viewer basic settings will be introduced later on in
this manual. The format is like this:
Server Name - Computer Name - Capture Time - Transmission Time - User Session Mode - Encryption
Server Name - The name given to the current video server
Computer Name - The name given to the connected computer
Capture Time - The time in ms it takes to capture a screen image
Transmission Time - The time needed to transmit the video screen image
User Session Mode - Current user session mode, shared, private, see only.
256-bit encryption - Currently used encryption mode
The below information is a capture example: "KLEv2" server, with "unnamed" computer, 46 ms to
capture video screens, 2 ms to send the screens, user shared mode, with 256-bit encryption.
Similar information can be found in the viewer menu: Information--> Connection Information
Viewer Performance
The video can be slow when connecting across the Internet. The image quality is depending on the
global bandwidth of the network. If the bandwidth is too small, 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.

4.3. Virtual Media
Remote Virtual Media
When running a viewer, you can share a DVD/CDROM, USB key, or ISO file with the computer
attached to KLEv2. For example, a CDROM in the drive of the computer running the viewer can
appear like a removable mass storage to the KLEv2-attached computer. Thus, from your remote
location, you can transfer files, install new programs or even install a complete OS into the attached
computer. Note that the transfer speed is limited by the network bandwidth, so it cannot be as fast
as a direct attachment.
If you share one of your hard drives, the attached computer can also write to your disk, provided
you did not check the option Disable Writes.
This page shows the current status of the connected Virtual Media and allows to forcefully
disconnect it. Specify whether the attached computer can or cannot write to the Virtual Media.
Figure 14: Remote Virtual Media

KLEv2 User's Manual
Rev 1.0 01/2016
- 18 -
Local Virtual Media
KLEv2 can get local access over the LAN to an ISO file shared by a Windows computer, or by another
machine emulating a Windows share (For example Linux with Samba server). Similarly to the
Remote Virtual Media feature, KLEv2 will emulate for the attached computer a removable mass
storage reflecting the ISO file. By nature this is a read-only storage. With this feature you can install
programs or boot the attached computer on the Virtual Media, provided the ISO file is the image of
a bootable disk.
Compared to the Remote Virtual Media, the Local Virtual Media is faster but limited to ISO files on
machines connected to the same LAN as KLEv2. The connection to the share does not involve the
viewer.
This page shows the current status of the connected ISO shared file. It allows you to set up the access
to the ISO file and to forcefully disconnect it.

4.4. KVM Server
Server Log
The Server Log keeps detailed record of events, errors, user logins and logouts, video modes, etc. It
also records each login attempt, even when the attempt is not successful. It provides certain
technical details such as compression ratio, encoding scheme, and bytes transmitted in each viewer
session. This is the place where you should go first to know the usage and state of your KLEv2.
This page is the place where you can see the log content, clear the log content, refresh the display
of the log, enable/disable the recording of statistical information about user connections.
Once the log file reaches its maximum size, oldest data is erase to give room to new data.
Each log entry is composed of the date plus time stamp, and the description of the event. The first
letter "K", "H" or "U" indicates whether the message is coming from the KVM server, the HTTP
server, or the USB server.
Figure 16: Server Log
Video Capture
Please note that the digital video capture is always set to optimal quality and speed. This page is not
relevant for digital video.
If the video is VGA, this page is the place where you can set up the level of quality and speed of the
video capture.
The setting here is use to balance the Video Quality against the Data Volume. Higher video quality
will generate larger data volume which will slow down the video transmission, especially across slow
Internet connections. Try to find a tradeoff between quality and speed.
