4. Advanced Setup for IP setting and
Firmware Upgrade
This section is in detail for how to assign IP address for KV-901T
and AV-901R, and how to upgrade firmware.
4.1 Setup IP address
A HTTP server is embedded in the KV-901T and AV-901R for
changing IP and firmware upgrade. However, the changing IP and
firmware upgrade is available only in Setup Mode, not in Normal
Mode.
For the AV-901R, there are 2 internal IP: the operation IP and
configuration IP. The operation IP is changeable but the
configuration IP is fixed at 192.168.168.22.
For the KV-901T, the operation IP is same as configuration IP.
Both of the KV-901T and AV-901R’s factory default operation IP is
shown on the label under the box. You can change the operation
IP, but please save and remember the final IP, otherwise, you will
not be able to configure the KV-901T. In case of missing the final IP,
you should use a special software tool to find IP out.
Please follow below steps to configure the operation IP settings:
Step 1: For the AV-901R, assign your PC IP address in between
192.168.168.1 and 192.168.168.254, excluding
192.168.168.22, and the subnet mask with 255.255.255.0.
For the KV-901T, the factory default IP is shown on the
label that stuck on the bottom of the KV-901T. The PC IP
address need to be on the same network as KV-901T. For
example, if the KV-901T IP is 10.100.1.10, you might set
your PC IP address as 10.100.1.1 and the subnet mask as
255.0.0.0.
Step 2: Unplug the power plug, hold the [Reset] button of the
device.
Step 3: Keep holding the [Reset] button and plug the power on.

11
Step 4: Release the [Reset] button when you see the [Status] (or
[Power]) LED starts blinking red.
Step 5: After the [Reset] button is released, in case of AV-901R,
the [Power] LED will become orange; in case of KV-901T,
the [Status] LED will become orange blinking. This
indicates the device is entered Setup Mode and you can
start to setup and get access to the HTTP server of the
device. If you are not in this status, any setup process is in
vain.
Step 6: Use a straight Ethernet Cable to connect the PC with the
device. (The [Status] or [Power] LED is still lit in orange.)
Step 7: Ping the connected device through the sequence, Start,
Run, cmd, ping [TX IP] or ping 192.168.168.22 (for RX). If
you receive the reply, it means the device is ready for
setup mode. Use IE browser to open the setup page. For
AV-901R, the URL is http://192.168.168.22. For KV-901T,
the URL is http://[TX IP]. In this page, you can change IP
address, subnet mask, gateway, device name, network
protocol and destination.
Device Name: the name of the device.

12
Network protocol: To be on the safe side, always use IP Layer, and
don’t use MAC Layer.
Destination:this setting is for KV-901T only. For one-to-one
application, you can use Unicasting. For one-to-many application,
you must use Multicasting.
Step 8: After click [Save] button, the settings will be saved and the
device will restart.
4.2 Firmware Upgrade
To upgrade the KV-901T and AV-901R, you should save the
new firmware into your PC first. Please disable antivirus software
and firewall until the firmware upgrade process is accomplished.
Step 1: Save the new firmware into your PC first.
Step 2: For AV-901R, assign your PC IP address to 192.168.168.11
and the subnet mask with 255.255.255.0.
For KV-901T, assign your PC IP address to the same
network as KV-901T. For example, if the KV-901T IP is
10.100.1.10, you might set your PC IP address as
10.100.1.1 and the subnet mask as 255.0.0.0.
Step 3: Hold the [Reset] button of the device.
Step 4: Keep holding the [Reset] button and plug the power on.
Step 5: The KV-901T [Status] or AV-901R [Power] LED will blink
red. Then you can release the [Reset] button.
Step 6: After the [Reset] button is released, in case of AV-901R,
the [Power] LED will become orange; in case of KV-901T,
the [Status] LED will become orange blinking. This
indicates the device is entered Setup Mode and you can
get access to the HTTP server for firmware upgrade.
Step 7: Use a straight Ethernet Cable to connect the PC with the
device. (The [Status] or [Power] LED is still lit in orange.)

13
Step 8: Ping the connected device through the sequence, Start >
Run > cmd > ping 192.168.168.22 or ping [KV-901T IP]. You
will receive the reply if the connection is established.
Disable the antivirus and firewall software and use IE
browser to get access the web server.
Type http://[IP]/upg.htm to upgrade the KV-901T firmware.
Type http://192.168.168.22/upg.htm to upgrade the AV-901R
firmware.
Step 9: Navigate to the firmware file and click [Upgrade]. Upgrade
process may take a few minutes. Please do not turn off PC
or the device or unplug the Ethernet cable. It will cause
damage of the device. After firmware upgrade is
accomplished, turn off the device.
Note: You have to disable antivirus software and firewall
software before you can upgrade firmware.
Firmware upgrade process cannot be interrupted so
please do not turn off your computer or the upgraded
device or disconnect the Ethernet cable until the
process is finished. Otherwise the system will crush.

5. Management Software
The system provides a Windows-based Management software
for the system administrator to manage all KV-901T and AV-901R
devices from his/her PC. You should download and install the
below software before installing this Management software.
.Net Framework 2.0 or above
WinPcap 4.1.2, Downloadable at:
http://www.winpcap.org/install/default.htm
To install, double click SETUP.EXE and follow the setup wizard:
After the installation is finished, you should configure your PC IP
address with the same network segment as all of KV-901T and AV-
901R units. Both of the KV-901T and AV-901R’s factory default
operation IP is shown on the label under the box. For example, if
the KV-901T and AV-901R operation IP is 10.100.1.10 and
10.100.5.70, then you might set your PC IP address as 10.100.1.1
and the subnet mask as 255.0.0.0.
Click “LAN Manager 5.0”icon to start the Management Software:

15
The Management screen is split into two frames: on the left is a
Tree view of the Transmitters (TX) and the connected Receivers
(RX); on the right is a two-tab view, one named “List & VWall”is a
List view of the RX, and the other, “Matrix”, is a matrix view of TX
and RX. The “List & VWall”tab, List tab for short, features one
intriguing function: Video Wall. The Matrix Tab displays a matrix
table in a coordinate style: the horizontal axis is a list of RX and
the vertical axis is of TX. If the intersected cell shows a light bulb, it
means the RX and TX is connected.
5.1 Change IP and change Name
Right-click the device you desire to change, and a context menu
will show up:
Select [Change IP] or [Change Name] and type the IP or name on
the pop-up window, and click [Submit]:

16
5.2 Reboot the device
Right-click the device you desire to reboot, select [Reboot] from
the menu.
5.3 Information
Right-click the device, select [Information], a window will pop up
with information about the device. The value in the version field
may or may not display the version; when it fails to detect the
version, it will display “N/A”.
5.4 Display the KV-901T video
When the KV-901T transmitter is connecting with at least one AV-
901R, it will have a [Display Screen] function enabled as below
picture.
Select a KV-901T transmitter and right-click the [Display Screen]
function, a window will pop up displaying that KV-901T screen
source. Depending on the performance of your PC and network
bandwidth, you can activate multiple windows for multiple KV-
901T screen sources.
The default frame rate for the KV-901T is 30 frames per second.
You can change the frame rate by clicking [Setting] > [Tx Frame
Rate Setting] on the upper left corner of the Management Main
screen. Click it and a window will pop up, and from here you can

17
specify the FPS (Frames per second) for the KV-901T transmitter (1
~ 30).
Note: This function is effective only on TX of version b204 or
above).

18
6. Managing Receivers and Video Wall
This section describes the functions of the List tab (“List &
VWall”).
6.1 Configuration Mode and Operation Mode
On the lower right corner, there are two buttons, the one
with a wrench icon is for Configuration Mode, and the other
with a wand icon is for Operation Mode. These two modes
are mutually exclusive, and the clicked one will be surrounded
with a red border line. In addition, the mouse pointer will turn
into an icon that resembles wrench or wand.
In Configuration Mode, also the default mode when the
program starts, users can do things related to configuration, like
arranging the locations of the RX, and setting up video walls. And
users can save the settings by click the “Save Settings”button ;
next time when the program activates, the tab panel will reveal
the layout as previously set.
In Operation Mode, users are allowed to actually make
receivers work; these works include switching from one
transmitter to another, setting UART baud rate, sending UART
messages, changing the connection method, rebooting, setting
receivers to an on or off state, and manipulating Video Wall.
6.2 Multi-Selecting RX
There are times when you may want to apply an action to
more than one RX on the List tab. The way to do it is simple: just
drag your mouse pointer over the panel, and there will appear a
filled rectangle, and the RX that resides within the region will be
selected.
(before selecting) (selecting) (selected)

19
6.3 Arranging RX Location
When the program starts, it will try to load settings from a setting
file that keeps a record of the RX location and Video Wall, and
display them on the List tab panel accordingly. It will also search
the network for RX; if an RX recorded in the setting does not exist
on the network, the RX icon will be shown with a gray-filled circle
in the lower left corner; otherwise, it will be shown with a green-
filled circle.
(on-line) (off-line)
If the setting file does not exist, the program will list the RX icon
starting from the upper left corner.
The network searching is not persistent; it is not going to go on
over and over, so it is possible that the program fails to detect all
of the RX on the network at a time, especially when there are
quite many RX. Or if the RX joins the network right after the
program finishes searching, the program will not detect the new
arrival. You will have to right-click on the List tab panel and select
“Reload”to recollect Rx from the network.
It’s easy to change the location of the RX; just make sure it’s in
Configuration Mode, and just use mouse pointer to drag-drop
them. One thing to notice is that you can multi-select RX, but you
cannot move them all; you can simply move one Rx at a time.
6.4 Managing Video Wall
6.4.1 Creating Video Wall
To create a video wall, here are steps:
first, select one or more RX, or even
select none; second, right-click and
select “Create Video Wall”in the
context menu. A new window will
show up as the picture on the right:
The default size is 2 columns by 2 rows. Change the size as you
wish by changing the drop-down. Note that the Rows are not
