Introduction
Thank You for choosing Lightware HDMI20-OPTC series devices. The
HDMI20-OPTC-TX/RX220-Pro is a HDMI 2.0 compatible extender pair for video, embedded
audio, RS-232 and Gigabit Ethernet signals, supporting uncompressed 4K UHD resolution
at 60Hz 4:4:4. This extender pair is particularly recommended for rental and staging
applications, 4K live events, and for future-proof operation centers.
According to the philosophy of Lightware’s optical extenders, the transmitter and the receiver
operate in pairs, so the transmitter is designed with LCD screen and jog dial control knob.
This is for controlling the transmitter itself but it also controls and is able to congure the
receiver.

1
AC connector
Standard IEC connector accepting 100-240 V, 50 or 60 Hz.
2
Fiber connector
Neutrik opticalCON DUO LC connector for optical data
transmission. The channel A carries the signal from the
transmitter to channel B in the receiver.
3
Boot button
Hidden button for special bootload function.
4
Break-out connector
The break-out LC connector is internally connected to the
channel B of Neutrik connector in the transmitter and the
channel A in the receiver. It is to carry any optical signal
from the break-out LC connector.
5
Laser LED
It gives feedback about the operation of the optical module. When
the laser is active (laser LED is ON), it radiates invisible waves
from the optical connector. Avoid eye exposure to the beam!
6
LAN
Two Neutrik etherCON connectors for Gigabit Ethernet (to
control the unit or for pass-through). Both are in the same
local network. Remote powering (PoE) is not possible.
7
TX: HDMI connector
RX: HDMI connector
Two HDMI 2.0 input ports and one HDMI 2.0 output port
for local display.
Three HDMI video output ports. Output signal depends on
the output conversion setting, see the details below.

Transmitter Side
The video signal is received at the Input 1 or the Input 2. The HDMI splitter duplicates the
signal and sends the same HDMI stream to the local HDMI output and the ber output.
Receiver Side
The video signal arrives via optical cable into the HDMI splitter. It duplicates HDMI stream
and transmits the signal without modifying it to the HDMI Out 2 port. The HDMI splitter
transmits the same signal into the video converter where three output conversion modes can
be set. It species how to deal with the HDMI 2.0 signal and what would be the output video
signal on the Out 1A and the Out 1B.
In Transparent mode (no conversion mode), the video signal is transmitted to the HDMI
Output 1A and the HDMI Output 1B without any changing.
Maximal data transmission capacity of Output 1B is 9 Gbps, if the video signal is above this
bandwidth, there will be no picture on the display.
Split mode means splitting of the original video signal into left and right halves and sending the
split signal to the HDMI Output 1A and the HDMI Output 1B.
In Downsample convert mode (convert to YCbCr 4:2:0) the video converter subsamples the
4:4:4 signal to 4:2:0 on the 1A and 1B Output port.

LCD Menu and Navigation
The front panel has a color LCD showing the most important settings and parameters. The jog
dial control knob can be used to navigate between the menu items or change the value of a
parameter (both the transmitter and the receiver). The knob can be pressed to enter a menu
or edit/set a parameter.
