Introduction
Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of
unique, creative, and affordable solutions to the vast range of problems that confront the video,
audio, presentation, and broadcasting professional on a daily basis. In recent years, we have
redesigned and upgraded most of our line, making the best even better!
Getting Started
We recommend that you:
•Unpack the equipment carefully and save the original box and packaging materials for
possible future shipment.
•Review the contents of this user manual.
Go to
www.kramerav.com/downloads/KT-205WM to check for up-to-date user manuals,
application programs, and to check if firmware upgrades are available (where appropriate).
Achieving Best Performance
•Use only good quality connection cables (we recommend Kramer high-performance,
high-resolution cables) to avoid interference, deterioration in signal quality due to poor
matching, and elevated noise levels (often associated with low quality cables).
•Do not secure the cables in tight bundles or roll the slack into tight coils.
•Avoid interference from neighboring electrical appliances that may adversely influence signal
quality.
•Position your Kramer KT-205WM away from moisture, excessive sunlight and dust.
Safety Instructions
Caution:
•This equipment is to be used only inside a building. It may only be connected to other
equipment that is installed inside a building.

an external connection, located next to the terminal or in the User Manual.
•There are no operator serviceable parts inside the unit.
Warning:
•If not using PoE, use only the optional power cord that is supplied for the unit.
•Do not open the unit. High voltages can cause electrical shock! Servicing by qualified
personnel only.

Using the Kramer Control agent
(connecting to Brain)
The KT-205WM touch panel contains a Kramer Control agent (an app), which connects to Kramer
Control.Kramer Control’s Brain creates customized interfaces which the Kramer Control agent
can display on the touch panel. The customized interfaces can control all aspects of a meeting
space. For more information about Kramer Brain, see https://www.kramerav.com/product/Kramer
Control.
When the touch panel starts, the Kramer Control
agent loads automatically (it is pre-installed on KT-
205WM). If an interface has been defined, it will be
displayed.
If this is the first time the Kramer Control app has run,
then it will ask you to enter the URL & port number of
the customized interface you have chosen to display.
Interface URL
The URL of the customized interface is generated by
KC-Brain or by your SL-240 / SL-280 interface. The
URL is always followed by a port number (and a code
on SL-240 / SL-280).
The hardware section of the builder’s Brain Info
contains the URL (in the format IP:port#) of the
customized Brain interface.
Port Numbers
Different versions of the Kramer Control Brain use
different port numbers:
1. Kramer SL-240 or SL-280: Port 8000.
2. KC-Virtual Brain 1: Port 8001.
Figure 8: Example of a touch panel interface
menu
3. KC-Virtual Brain 5: Ports 8001 – 8005 (KC-Virtual Brain 5 can define up to 5 different touch pad
control interfaces, each will use a different port).
Figure 9: Interface IP Address

Updating the interface URL in the Kramer Control agent
There are 3 possible methods of updating the interface URL in the Kramer Control agent:
1. In the Kramer Control agent (on the touch panel screen).
2. In a web browser (on a remote computer connected to the same network).
3. In the Brain software (setting up the touch panel in the Brain software).
Any one of these methods can load the interface URL into the touch panel’s Kramer Control agent.
1. Entering the interface URL in the Kramer Control agent
a. Kramer Control agent opens automatically when the touch panel starts. If no interface
URL has been entered, this is how the screen looks:
Figure 10: Touch panel running the Kramer Control agent
•If the touch panel is not displaying the Kramer Control agent, open the Kramer
Agent app from the touch panel’s Home page.
b. Press LAUNCH CONTROL INTERFACE, the URL entry pop-up appears.
Figure 11: Kramer Control agent, URL entry pop-up
c. Enter the IP address and port of the interface that was defined in Kramer Brain, for
example https://192.168.88.180:8001.
d. By default, the K-Control slider is on, setting the tablet in “Immersive Mode”. In
Immersive (full screen) mode, the system bars are hidden and users can exit the
interface only by swiping up and entering a PIN. Immersive mode is recommended for
the Kramer Control interface; Disable it if you are using a generic webpage.
e. Press OK and the touch panel will load your interface. To exit the interface and access
touch panel controls, slide your fingers up from the bottom of the screen and enter the
PIN (default 9428).

2. Entering the Kramer Control URL from a browser on the
same network
The following is an alternative method to setting the Kramer Control link on the touch panel.
This procedure can be done remotely, without using the touch panel.
Note: The touch panel must be switched on and connected to the same LAN.
a) Open a browser window on a computer connected to the same network as the touch
panel.
b) Enter the interface URL in the following format:
https://<IP of the touch panel>:9804/launchkramerurl?<IP of the brain interface>:<port #>
For example: if the touch panel’s IP is 192.168.0.56 and the Brain interface’s IP is
“192.168.22.53:8001”, then you would enter
https://192.168.0.56:9804/launchkramerurl?192.168.22.53:8001
Note: The touch panel port (on the first URL) is 9803 for http and 9804 for https.
If there is more than one interface on the brain it is recommended to copy and paste the
highlighted portion of the URL from a browser tab showing the correct interface.
After this command is sent, the touch pad will display the Brain-defined interface.
The following interface commands for the touch panel can be sent from a browser:
a) Check if the agent is running: https://<IP of the touch panel>:9804/health/
Successful response: {"Status”:”up”}
b) Reboot the touch panel: https://<IP of the touch panel>:9804/reboot/
Successful response: {“Status”: “Rebooting”}
c) Clear the interface URL definition in the Control app:
https://<IP of the touch panel>:9804/reseturl/
Successful response: {“Status”: “URL is reset now”}
d) Define a new interface URL:
https://<IP of the touch panel>:9804/launchkramerurl?<IP of the interface>:<port#>
Successful response: Browser will be launched with given URL.
e) Define a generic URL (have the touch panel display a non-Brain URL such as
https://www.google.com: https://<IP of the touch panel>:9804/launchurl?<full generic URL>
Successful response: Browser will be launched with given URL.
Figure 12: Example of a successful response message.
