1. INTRODUCTION
With HDMI becoming more and more popular around the world,
many consumers have been searching for a way to transmit HDMI
signals over very long distances. The HDMI to Optical Transmitter
and Receiver set which uses fiber optical cables will give you longer
transmission distances (up to 300m) while also providing you with
thinner, lighter cables for easier installation. With this system the HDMI
signal is not compressed and is fully compliant with HDMI and HDCP.
2. APPLICATIONS
• IR & RS-232 control over fiber optical
• Digital signage, airport displays, advertising, video walls or special
events
• Surveillance systems
3. PACKAGE CONTENTS
• HDMI to Optical Transmitter
• Optical to HDMI Receiver
• 2 x 3.5 mm phone jack to D-Sub 9pin converter cables
• 1 x IR Extender
• 1 x IR Blaster
• 2 x 5 V DC Power Adaptors
• Operation Manual
4. SYSTEM REQUIREMENTS
Input source devices such as DVD or Blu-Ray players with HDMI cables
and output displays such as HDTV’s and monitors with HDMI ports.

1 OPTICAL LED: This blue LED will illuminate when at least one
optical cable is connected and has successfully detected and
communicated data between the Transmitter and Receiver.
Note: If the LED is not illuminated then users will need to check
the connection of the fiber cable between the Transmitter and
Receiver units and then check the connection is good and that
the cable itself is correct and undamaged.
2 ERROR LED: This red LED will illuminate when there is an error in the
input signal data rate that is higher than 75/170MHz (Single/Dual).
Double Check all connections and make sure they are properly
connected.
3 HDMI LED: This blue LED will illuminate when the Transmitter unit is
receiving a HDMI signal from the source device.
4 HDMI INPUT: Connect to an HDMI input source such as a DVD or
Blu-ray player with a HDMI cable.
5 IR-OUT: Connect to the supplied IR blaster cable for IR signal
transmission. Place the IR blaster in direct line-of-sight of the
equipment to be controlled.
6 RS-232: Connect to a PC or laptop (with supplied 3.5mm phone
jack to D-Sub 9pin adaptor) for the transmission of RS-232
commands.
7 OPTICAL SUB & MAIN: Connect the Transmitter and Receiver units
with 2-way fiber optical cable to transmit the data signal
Note: Connector Type: LC-LC, Fiber: Duplex Single-mode Fiber
8 DC 5V: Connect to the power adaptor included in the package
from the AC wall outlet for power supply.

2 HDMI LED: This blue LED will illuminate when the device is
successfully communicating with the display.
3 ERROR LED: Under normal conditions, this red LED will not illuminate
but will blink for few seconds when startup of the the device.
When the LED is illuminated constantly, it means the HDMI output
is not able to output a HDMI signal. Double check the connection
and also make ensure the source is sending a compatible HDMI
signal. Check all connections and make sure they are all properly
connected.
4 HDMI OUTPUT: Connect to a HDMI Display device, such as a TV or
monitor, with a HDMI cable.
5 IR-IN: Connect to the supplied IR Extender cables for IR signal
reception. Ensure that remote being used is within the direct lineof-sight of the IR extender.
6 RS-232: Connect to the device that is to be controlled (with the
supplied 3.5mm phone jack to D-Sub 9pin adaptor) by RS-232
commands
7 OPTICAL SUB & MAIN: Connect the Transmitter and Receiver units
with 2-way fiber optical cable to transmit the data signal.
Note: Connector Type: LC-LC, Fiber: Duplex Single-mode Fiber
8 DC 5V: Connect to the power adaptor included in the package
from the AC wall outlet for power supply.
