4.4. PoC Solution
The AVG-K12 is designed for simplicity of use and simplicity of installation. The
installation requires a single CAT cable form the Receiver to the transmitter wallplate
and a single cat cable from the wallplate to the control panel. Both the control panel
and the HDBT wallplate transmitter are powered over the Cat cable from the HDbaseT
Receiver.
4.5. System Applications
The AVG-K12 is designed to be used in educational environments. It has been
designed specifically to make the teacher’s job easier without having to worry about
getting the equipment to work. The system provides easy switching between sources
and annotating important notes on the whiteboard in class.
This section provides a brief introduction to scenarios the user may come across.
Scenario 1: Before Class
1. Press the “ON” button of the Control Panel to turn the projector on or long-press it
to start the system.
2. Connect HDMI signal sources (e.g. PCs) to the HDMI IN 1 and/or HDMI IN 2 / VGA
port of Transmitter.
3. Turn on wireless microphone.

3. Position your remote close to the IR receiver on the control panel, press the
button your remote that you want to learn in as the ON IR code.
4. Once the IR code has been learnt successfully, the button “ON” will stop
blinking
5. Next, repeat the above steps to learn the IR code into the “OFF” button.
6. Finally, Long-press the button “HDMI 2 / VGA” to exit programming mode.
▪To Test your IR codes:
1. Press the button “ON” to turn on the projector.
2. Press the button “OFF” to turn off the projector.
Notes:
▪When the system enters IR learning status, long-press the button “HDMI 2 / VGA”
for more than 5 seconds to exit IR Learning.
▪If you don’t do anything for 60 seconds, the system will exit IR Learning
automatically.
▪The blue backlight of all buttons will go out when the system exits IR Learning
successfully.
5.2. Front Panel Control
▪Via Control Panel
▪There are two modes for controlling the projector and system: synchronous
and asynchronous control mode. This can be selected via the web-based
GUI. For more details, please refer to the 5.6.2 Setting Menu.
▪Synchronous control:
Press the buttons “ON” or “OFF” on Control Panel to turn on/off the projector
and system concurrently on or off.
▪Asynchronous control:

AVG-K12-VGA
▪Via the Transmitter
Press “SOURCE SELECT” to select one source, press again to select next
source, toggling between HDMI IN 1 and HDMI IN 2 / VGA.
Press “RESET” to reboot Transmitter.
5.3. USB Signal Return
The Receiver has a USB port (FROM TOUCH SCREEN) to connect with a Smart
Board. When the user makes notes on the smart board, the Receiver will receive the
signal from Smart Board via USB cable and send it back to the HDMI signal source
(PC), and then it will be transmitted to the projector for display. Please refer to the
return path of USB signal as shown below.
Note: The distance between the Receiver and the Smart Board should be within 4m,
otherwise a special USB extension cable should be used.
