Thank you for purchasing our KLE-Z IP-based KVM Switch Console. We recommend that you read this manual thoroughly and retain it for future reference.
I. Introduction
The KLE-Z is the latest generation of IP-based KVM Switch Console for remote Server/KVM switch
management. It allows remote management of Server(s) or KVM switch(es) over the Internet/LAN. In
addition to supports for secured access via 1024-bit PKI authentication, 256-bit SSL data encryption,
LDAP, RADIUS, and Active Directory authentication, it has virtualization of ISO file that allows accessing of
remote drive to help manage server. Moreover, it builds in a 2-port Ethernet hub which means while one
port is connected to the network, the other one can still be used by another Ethernet device, such as a
PC, to connected to the network as well.
The KLE-Z provides a solid, reliable, and physical extension of keyboard, mouse, and video to nearly
unlimited distance. It supports for both analog and digital videos through its DVI-I connector. Using two
passive DVI-to-VGA video adapters implements VGA signal transmission from the system (VGA PC) end
to the console (VGA Monitor) end.
The KLE-Z's gives users a complete control from PC's pre-boot stage such as BIOS-level CMOS setting
with its USB interface. It even realizes a remote Power ON/OFF control to its attached PC/Server with an
external PDU(Power Distribution Unit). With properly planning the KVM infrastructure with the virtual
media, users can even reinstall a new operating system at any server connected to the KLE-Z, feeling free
and confident while remotely accessing the local attached system.

7.2 First Access to KLE-Z Web Management
The factory default network settings for the KLE-Z 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 IP address to enter the KLE-Z Web Management:
■https://192.168.1.200:5908
(*The exemplary port number 5908 here is based on a TCP Port Base 5900 plus 8; please refer to the
subsection 7.3.1 Configuring the TCP Port Base)
The default User name and Password for the System Administrator are:
■User name: superuser
■Password: superu
1. Log in the KLE-Z Web Management at its default IP address https://192.168.1.200:5908 using your
computer web browser. If you failed to access the KLE-Z Web Management at this address, it might be
possibly this default IP address has been occupied by another device. Please use KCenter or Getipdev
application (refer to the support CD) to find out an available IP address for the KLE-Z. Then use that IP
address followed by a port number (Refer to the subsection 7.3.1 Configuring the TCP Port Base) to
enter the KLE-Z Web Management.
2. Alternatively, you can also build an isolated network, without connecting it to LAN or Internet,
simply between the KLE-Z and a computer via a Cat.5/6 cable. Set up an IP address for the computer
that is in the same network segment as the KLE-Z such as 192.168.1.xxx, then enter the KLE-Z Web
Management at its default access IP address https://192.168.1.200:5908
* When you first access the KLE-Z Web Management, your browser may prompt a security warning message. Please choose
"Continue to this website" since there is no risk of pirate website here. These warnings are not relevant for the HTTPS server
of the KLE-Z unit. However, you can install a Root certificate of the KLE-Z in the list of trusted CA (Certificate Authority) if you
want to permanently remove this warning message. (Refer to more details in the chapter XI. Troubleshooting)

12
7.3 Networks
7.3.1 Configuring the TCP Port Base
(1) Log in the KLE-Z Web Management as instructed in the previous chapter. Expand Main on the left-
side menu list and click Networks.
(2) Specify a port base for IPViewer's connection in TCP Port Base option. You can choose any available
port base, starting from 5900 with an increment of 10 right up to 6400. The TCP port base plus 8 will
be the port number to enter KLE-Z Web Management.
(3) Specify a host name you prefer, i.e., the name that KLE-Z will assume on your LAN. Or, you may click
Set Default button to load a default unique host name composed of the product name and the
hardware MAC address.
7.3.2 Ethernet IP Settings
Key in the factory default network settings in the section 7.2 First Access to the KLE-Z Web Management.
Please refer to the Help hyperlink for more information.

13
7.3.3. Wireless IP Settings
This subsection will be hidden if you do not have an 802.11 compatible USB
Wifi Adapter plugged into the Wifi Extension Port on the KLE-Z unit. It's strongly
recommended that you use a WPA/WPA2 wireless connection since older protocols
such as WEP are unsecured.
(1) Check the Enable Wireless Interface checkbox to activate the wireless interface. Wait until the service
starts up and the wireless setting form is ready.
(2) In the Network Name (SSID) drop-down list, select an available wireless network (SSID) you want
to connect to. If you do not know it, please seek assistance from your Network Administrator. If the
wanted SSID does not appear on the list, try to click the Scan button. Eventually, if you still keep
failing to connect to your wanted SSID, this is more likely that the wireless access point is out of
reach.
(3) Please refer to the Help hyperlink and fill in with proper wireless settings. We recommend you let the
wireless router or access point themselves configure the KLE-Z by checking the Use DHCP checkbox.
7.3.4. Store Settings
Click the Store Settings button to save your new network settings. Press the Soft Restart button at the
upper-right corner of the page then the KLE-Z will apply and validate these new network settings after it
restarts. The new IP address for the KLE-Z Web Management will become:
https://<IP Address>:<TCP Port Base + 8>
For example, if your IP address is set at 192.168.1.192 and the TCP Port Base is set to 5920, then the new
addresses to enter the IPViewer and the KLE-Z Web Management will respectively become:
IPViewer: https://192.168.1.192:5920
KLE-Z Web Management: https://192.168.1.192:5928
Important Notes
The Ethernet port and the Wireless port can not work simultaneously. So, if you plan to use the wireless
alone, i.e., without Ethernet cable, please assign the Ethernet port to a different network segment to
avoid IP conflicting. For example, if the IP address of the wireless port is 192.168.1.xxx, you could set the
Ethernet Port to 192.168.2.xxx (network mask = 255.255.255.0).
Make sure you report all information about the KLE-Z to your Network Administrator so that he could
make corresponding adjustments to the firewalls, network configurations, and DMZ of routers. This
enables the KLE-Z to function properly when accessed from remote locations over the Internet.

7.4 Log in to the IPViewer
There are three available versions of the viewing application named IPviewer to access the KLE-Z on
different platforms (Windows®, Java®, Android®.) The KLE-Z captures the video from its attached
computer and transmits it to the IPViewer application. It also receives the signals from the keyboard and
mouse attached to the KLE-Z and emulates an USB keyboard and a mouse on the attached computer.
Please download and install a preferred version of the IPViewer application to be run in the platform you
are using.
7.4.1 Downloading the IPViewers
Three IPViewers can be downloaded from the KLE-Z Web Management: Download (Menu) --> Viewers
(Menu item). You may run the IPViewer for Java® on cross-platforms with Java®Runtime Environment
such as Windows®, Linux®, MacOS X®, etc. Note that Android®users should download an apk application
at the provided link on the webpage below then manually install it on their Android®devices for use.
* It's recommended always keep your Java®Runtime Environment most updated.
7.4.2 IPViewer for Windows®
1. Download and install the IPViewer for Windows®according to the following instructions.
2. On the Windows® desktop, click the IPViewer icon to launch the IPViewer application. Key in your
User ID and Password in the following User Authorization window.

15
3. In the Connection Dialog window, key in the access address for the IPViewer <IP_address>:<TCP
Port Base> then click Connect. After the KLE-Z is identified, the IPViewer will pop up an User
Authentication window. Key in the User ID (i.e. superuser) and Password (superu) respectively and
click OK to proceed.
7.4.3 IPViewer for Java®
This IPViewer application comes with .jar file format which can be run on any computer-platforms with
the most updated Java®Runtime Environment. Since the IPViewer for Java® doesn't need to be installed
as the Windows® version, if you need to frequently use it, we recommend you download and save it
(mkview-dist.jar) at a convenient path, such as the desktop. Double click this .jar file and a Connection
Details window will pop up. If the computer-platform fails to automatically associate the Java®virtual
machine to this .jar file, try opening a terminal window then run it by typing "java -jar mkview-dist.jar"
After you key in the IP address to access the IPViewer as mentioned above, press the OK button and a
warning window shall pop up. Please follow its instructions to install a required library in advance.
If you haven't installed this required library, you could still log in the IPViewer for Java® after the User
Authentication procedure. But a warning window as below will pop up to forcibly terminate the IPViewer
application. So we highly recommend you install the most updated Java®Runtime Environment as well
as this required library before you run the IPViewer for Java®.

VIII. KLE-Z Web Management Instructions
The KLE-Z Web Management is the main administrative interface for the KLE-Z unit. This chapter will go
into details to introduce more useful instructions in each sections. You could also get more instructive
information by clicking the Help hyperlink on each page.
8.1 Download
Refer to the subsection 7.4.1 Downloading the IPViewers.
8.2 Main
8.2.1 Date and Time
Specify the locale and time settings. It is recommended check the Internet Time checkbox to synchronize
the KLE-Z with an Internet Time Server (NTP).
8.2.2 Security Settings
Users can upload Certificates and Keys or specify the encryption level of connections and the password
policy according to their needs.
8.2.3 Networks
Refer to the Section 7.3 Networks.

17
8.3 Virtual Media
8.3.1 Remote Virtual Media
When running the IPViewer, the user could share a DVD/CDROM, an USB drive, or even an ISO file
at a remote location with the computers attached to the KLE-Z at a local location. For example, as
the computer at the remote location running the IPViewer application shares its CDROM drive, the
computer attached to the KLE-Z will see a removable mass storage device appeared for its access. Thus,
from the remote location, you can transfer files, install new programs or even re-install a new OS onto
any computers attached to the KLE-Z. Note that the data transfer speed will be limited by the network
bandwidth, so the user may expect an inferior data transfer performance since it is not a physical device
connection.
If you share one of your hard drives at the remote location, the attached computers at the local location
are able to write them, unless you check the Disable Writes checkbox.
This page concisely shows the current status of all connected Remote Virtual Media and allows the user
to disconnect them with the Disconnect button or reconnect them with Reconnect button afterwards.

18
8.3.2 Local Virtual Media
KLE-Z can access over the LAN to an ISO file shared at the local location by a Windows® computer using
SMB Share protocol, or by a Linux® computer with Samba Server functioning the same. Similar to the
Remote Virtual Media feature as aforementioned, the KLE-Z emulates an ISO file at the local location as
a removable mass storage for the KLE-Z's local attached computers. Compared to the Remote Virtual
Media, though the access to the Local Virtual Media is faster but is still limited by the size of the ISO file
at the computers connected to the same LAN as KLE-Z.
This page shows the current status of the connected ISO file. It allows the user to set up the access to
the ISO file and to forcibly unmount it with the Unmount button or re-mount it with the Mount button
afterwards.

19
8.4 KVM Server
8.4.1 KVM Server Log
The Server Log keeps detailed records of events, errors, user logins and logouts, video modes, etc. It also
records each login attempt, even for an unsuccessful one. It provides various technical details such as
compression ratio, encoding scheme, and bytes transmitted. In this page you can clear the log content by
clicking the Clear button. Note that the server log will be forcibly erased each time you perform a reboot
remotely by clicking the Reboot Device button in Maintenance (Menu) --> Reboot (Menu item) or when
KLE-Z suffers a power loss. Once the log file reaches its maximum size, oldest data will be erased to give
room for 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" respectively represents whether the message comes from the KVM server, the HTTP
server, or the USB server in the KLE-Z.
8.4.2 Video Capture Settings
Please note that the digital video capture has been automatically set with optimal quality and speed
and not adjustable by users.
Most of these settings here only apply to VGA analog signal. The goal here is to balance between the
Video Quality and the Data Volume. Higher video quality generates larger data volume which increases
the video transmission time. Please try to find out an optimal tradeoff between video quality and speed
especially in slow Internet connection.

20
8.4.3 Viewer Connection Settings
This page correlates to IPViewer's connection settings:
■Assign a Server Name for the IPViewer, i.e. KLE-Z, as displayed on the title bar of the IPViewer window.
■Select a Keyboard layout you are using which is consistent with the KLE-Z's attached computers.
■Checking the Mouse and Keyboard Sharing checkbox only allows the first IPViewer client connected
to the KLE-Z to access keyboard and mouse. As the first IPViewer client disconnects, the client in the
second sequence will automatically get the access of keyboard and mouse.
■Check the Double-Byte Languages checkbox for users who use a double-byte language, such as
Chinese, Japanese, Korean, etc.
■Select a sequence of keystrokes as hot-keys for Mouse re-synchronization in the Mouse-
Resynchronization Keys option. Note that the hot-keys won't work while KLE-Z is emulating a mouse
with absolute coordinates.
■Preset up to 32 keyboard shortcuts in the Shortcuts list. The Shortcuts represent sequences of
keystrokes which can be submitted by the IPViewer with a simple mouse click. An practical scenario,
for example, is to call the KVM OSD menu while KLE-Z is connected with a KVM switch.
8.4.4 Attached KVM Switch
Whenever KLE-Z is connected with a KVM switch, you may also setup the KVM hot-keys for selecting
the active port you want.
