Introduction
The ST121HDFXA is a long-range HDMI® video extender kit that uses SC ber optic
cable to extend video / audio from an HDMI®-equipped device up to 2600 feet
(800 Meters) to a remote display. The extender supports full High-Denition video
(1920x1200 / 1080p), and includes both the transmitter and receiver, for a complete
ready-to-use digital signage solution.
Not only is this an incredibly long range solution that can extend an HDMI® signal
across or between buildings , but because ber optics transmit data using light rather
than copper, it will not cause or be eected by electromagnetic Interference (EMI).
For convenient, time-saving control of the media source, the HDMI® extender also
oers Infrared (IR) extension, which enables you to control the HDMI® audio-video
source from either end of the connection. The kit also includes optional mounting
hardware for a clean and professional installation.
The ST121HDFXA HDMI® over Fiber Optic Extender kit is backed by a StarTech.com
2-year warranty and free lifetime technical support.

Preparing Your Site
1. Determine where the local video source (i.e. computer, Blu-ray Player) will be
located and set up the device.
2. Determine where the remote display will be located and place/ mount the
display appropriately.
NOTE: Ensure the Transmitter Unit and the Receiver Unit are situated near an available
AC electrical outlet. Make sure all devices are turned o before beginning installation.
Hardware Installation
1. Install Transmitter Unit
a) Position the Transmitter Unit near the video source (i.e. Computer, Blu-ray Player).
b) Connect an HDMI® cable from the video source device (i.e. computer, Blu-ray
Player) to the “HDMI® IN” on the Transmitter Unit.
c) Connect the provided Transmitter Unit power supply.
d) (Optional) If using the ST121HDFXA to extend an infrared (IR) device signal.
Connect the IR Transmitter Cable to the IR Transmitter port on the Transmitter Unit,
and Position the extended IR sensor directly in front of the video source’s IR sensor.
Check the manual of your video source device for the IR sensor location.
2. Install SC-SC terminated Fiber Optic Cable
a) Connect an SC-SC terminated Fiber optic cable SC-SC Fiber Connector on the
Transmitter unit.
NOTE: Ensure you have enough Fiber cabling to connect the Transmitter Unit to the
Receiver Unit’s location, and that each end is terminated with an SC-SC connector.
The cabling should not go through any networking equipment (i.e. router, switch).
b) Connect the other end of the ber cable run to the SC-SC connector on the
Receiver Unit ensuring the SC connector connect to TX the transmitter is connect to
RX on the receiver and vise-versa.
NOTE: The multi-mode untwisted-pair ber optics cable (50/125 and 62.5/125)
terminated with SC duplex connectors is recommended to use for the
interconnection between Local Unit and Remote Unit. The table below shows
the specications.
NOTE: The system will disable the video output signal when it detects non-HDCP
compliant display(s) on playing the HDCP video source. All the connected output
displays MUST be HDCP compliant, when the video source is HDCP compliant.
