1. INTRODUCTION
This transmitter and receiver set is a great solution for extending UHD
video and audio as well as Ethernet and control via a single run of
Cat.5e/6/7 cable over distances up to 100 meters. This extender
set complies with the advanced HDCP 2.2 and HDMI 2.0 standards,
as well as supporting the legacy HDCP 1.x and HDMI 1.x standards.
Despite HDBaseT’s 10.2Gbps bandwidth limitation, 4K UHD HDMI video
sources, up to and including 4K@60Hz (4:4:4, 8-bit) as well as 10/12-
bit sources with HDR, are able to be processed and extended by the
use of AVLC (Adaptive Visually Lossless Compression) when needed.
Multiple data and control interfaces are also provided, including IR,
RS-232 and LAN connections. The Receiver (PD) is powered by 48V
PoH (Power over HDBaseT) provided by the Transmitter (PSE), allowing
for greater flexibility within different installation scenarios.
2. APPLICATIONS
• Household entertainment sharing and control
• Lecture room display and control
• Showroom display and control
• Meeting room presentation and control
• Classroom display and control
3. PACKAGE CONTENTS

• 1×HDMI over HDBaseT Transmitter (with LAN, IR & RS-232)
• 1×48V/0.83A DC Power Adapter
• 1×Power Cord
• 1×3.5mm to IR Blaster Cable
• 1×Operation Manual
Receiver
• 1×HDMI over HDBaseT Receiver (with LAN, IR & RS-232)
• 1×3.5mm to IR Extender Cable
• 1×Operation Manual

4. SYSTEM REQUIREMENTS
• HDMI source equipment such as a media player, video game
console or set-top box.
• HDMI receiving equipment such as an HDTV, monitor or audio
amplifier.
• The use of “Premium High Speed HDMI” cables, and industry
standard Cat.6, Cat.6a or Cat.7, is highly recommended.
5. FEATURES
• HDMI with HDR, 3D & 4K@60Hz support, DVI 1.0 compatible
• HDCP 2.2 and HDCP 1.x compliant
• Supports up to 4K UHD (18Gbps, 4K@50/60Hz 4:4:4, 8-bit) video input
• Supports output resolutions up to 4K@50/60Hz (4:4:4, 8-bit)
• Supports Deep Color input and output up to 12-bit
• Supports 10-bit and 12-bit HDR bypass
• Supports CEC bypass
• Simultaneous transmission of video, audio and data over a single
Cat.5e/6/7 cable up to 100m (328ft) at 1080p and 70m (246ft) at 4K
• Supported HDBaseT feature set: HD Video & Audio, 100BaseT
Ethernet, 48V PoH, and Control (Bidirectional IR/RS-232 pass-
through)
• Integrated AVLC (Adaptive Visually Lossless Compression) activates
when the bandwidth requirements of the source are beyond
10.2Gbps (340MHz) allowing for support of sources up to 18Gbps
(600MHz) with no loss of visual quality
• The AVLC function allows manual selection between High Quality
(Full bandwidth) mode and Standard mode (Lower bandwidth,
useful for longer cable runs with 4K sources)
• Supports standard IEEE 802.3 AT 48V PoH from Transmitter (PSE) to
Receiver (PD) (compatible Receivers only)
Note: The 48V PoH function is designed for powering compatible
Receiver units only. Non-PoH Receivers will need their own power
supply. Receivers from other brands may not be compatible.

6. OPERATION CONTROLS AND FUNCTIONS
6.1 Transmitter's Front Panel
STD/HQ: This switch allows user to select which compression mode
to use when AVLC is active. HQ (High Quality) mode uses the
least amount of compression and provides the highest possible
visual quality (perceptually identical to the original). STD (Standard
Quality) mode applies additional signal reduction methods to
lower the bandwidth requirements of 4K sources further, improving
transmission reliability over longer cable runs at the cost of some
visual fidelity.
ISP: This button is reserved for factory use only.
STD/UPDATE: This switch is reserved for factory use only. The default
setting is “STD”.
RS-232 IN: Connect to a PC, laptop or other serial control device
for the extension of RS-232 signals.
LAN: Connect to an Ethernet supporting device or to your local
network, as appropriate, to extend the network to both ends of
the HDBaseT connection.
SYNC LED: This LED will illuminate when a live input source is
detected.
HQ/STD LED: This LED will illuminate whenever the AVLC function
is active. A green LED indicates that AVLC is in HQ (High Quality)
mode. A red LED indicates that AVLC is in STD (Standard) mode.
POWER LED: This LED will illuminate to indicate the unit is on and
receiving power.
LINK LED: This LED will illuminate solidly when a live connection with
a compatible Receiver is active. The LED will blink with a regular
pattern if a Receiver is connected but there is not currently a live
signal. The LED will blink with an irregular pattern if a connection
error has occurred.

6.2 Transmitter's Rear Panel
DC 48V: Plug the 48V DC power adapter into this port and connect
it to an AC wall outlet for power.
IR1 BLASTER: Connect to the provided IR Blaster to transmit IR
signals to devices within direct line-of-sight of the IR Blaster.
IR2 EXTENDER: Connect to the provided IR Extender to extend
the IR control range of remotely located devices. Ensure that the
remote being used is within direct line-of-sight of the IR Extender.
CAT5e/6/7 OUT: Connect to a compatible HDBaseT Receiver with
a single Cat.5e/6/7 cable for transmission of all data signals.
HDMI IN: Connect to HDMI source equipment such as a media
player, game console or set-top box.
6.3 Receiver's Front Panel
ISP: This button is reserved for factory use only.
STD/UPDATE: This switch is reserved for factory use only. The default
setting is “STD”.
RS-232 OUT: Connect to a serial controllable device for the
extension of RS-232 signals.
LAN: Connect to an Ethernet supporting device or to your local
network, as appropriate, to extend the network to both ends of
the HDBaseT connection.
