3.5 Application
HDBaseT Educational Kit has a good application in educational system. It is designed for
solving some difficult issues, such as teacher cannot freely switch signal sources and
annotate some important things on whiteboard in class. This section provides a brief
introduction to the major application scenarios.
⚫Scenario 1: Before Class
1. Press the button “ON”of Control Panel to turn on the projector or long-press it to start
system.
2. Connect HDMI signal sources (e.g. PCs) to the HDMI IN 1 and HDMI IN 2 port of
Transmitter.
3. Turn on wireless microphone.

4. System Operation
4.1 IR Learning Function
IR learning function allows user to use the buttons of Control Panel to displace some keys
of IR remote to control projector or other devices. Control Panel has four buttons: “ON”,
“OFF”, “HDMI 1”, “HDMI 2”, but “HDMI 1”, “HDMI 2” do not support IR learning function,
because they are designed for switching HDMI signal sources.
⚫Operation Procedure:
1. Long-press the button “HDMI 1”until the buttons “ON” and “OFF” light up, and
then release “HDMI 1”, the blue backlight of “HDMI 1” will goes out to enter IR
learning mode.
2. Press the button “ON” to enter IR learning status, and it will keep blinking blue.
3. Press the corresponding button (such as “Open” button) on IR remote,
meanwhile, put IR remote close to the IR sensor of Control Panel.
4. Once user set up successfully, the button “ON” will stop blinking.
5. Next, repeat the above steps to set another button “OFF”.
6. Finally, Long-press the button “HDMI 2” to exit programming mode.
⚫Realization of IR learning function:
1. Press the button “ON” to turn on the projector.
2. Press the button “OFF” to turn off the projector.

When the system enters IR leaning status, long-press the button “HDMI 2” for
more than 5 seconds can exit.
If there is no operation for 60 seconds, the system will exit automatically.
The blue backlight of all buttons will go out while the system exits successfully.
4.2 Front Panel Button Control
▪Via Control Panel
There are two modes for controlling projector and system: synchronous and
asynchronous control mode. They can be selected via web-based GUI. For more
details, please refer to the 4.6.2 Setting Menu.
