1. INTRODUCTION
This 4K UHD+USB-C over HDBaseT transmitter uses HDBaseT 3.0, the
newest generation of HDBaseT technology, and is the perfect solution for
extending full bandwidth (18Gbps, 4K@60Hz 4:4:4) video signals with
HD audio via a single run of Cat.6A/7 cable over distances of up to 40
meters. Multiple control and data signals may also be transmitted along
with the audio and video, including IR, RS-232, and USB 3.0. Additionally,
the inclusion of a USB-C connection as its input allows for the combination
of video, audio, and USB over a single cable from the connected source
device, greatly enhancing installation practicality. This transmitter is ideal
for use in any video extension scenario, especially when latency-free,
uncompressed, high resolution video is critical, such as medical installations,
live conferences, and education.
2. APPLICATIONS
• Household entertainment sharing and control
• Lecture hall/classroom display and control
• Meeting room presentation and control

1HDMI OUT port: Connect to an HDMI TV, monitor, or amplier for digital
video and audio output.
2AUDIO IN 3-pin Terminal Block: Connect to the analog audio output
of a device such as a media player or game console using a 3-pin
adapter cable. Audio is sent to the analog audio output on the connected
compatible receiver.
3AUDIO OUT 3-pin Terminal Block: Connect to powered speakers or
an amplier for analog audio output using a 3-pin adapter cable. Audio
is sourced from the analog audio input on the connected compatible
receiver in bypass mode, or from the USB-C port in extract mode.
4RS-232 4-pin Terminal Block: Connect to a PC, laptop, or serial
controllable device with a 4-pin adapter cable for the extension of
RS-232 signals between both ends of the HDBaseT connection.
5IR 4-pin Terminal Block (In/Out): Connect to both an IR Blaster and
Extender using a 4-pin Y-adapter cable to transmit and receive IR control
signals and extend them to devices connected to the other end of the
HDBaseT connection.
6USB 2.0 Ports (Type-A): Connect directly to a standard USB device
such as a mouse, keyboard, or ash drive to extend their USB
functionality to the currently active USB host port.
7AUDIO Button: Press this button to toggle the transmitter’s analog audio
out stream source between the receiver’s analog audio input (bypass)
and the USB-C input’s audio (extract).
Note: Audio extraction is only available with LPCM 2.0 sources. Pressing
this will also change the setting on compatible receivers.
