Introduction
The ST121UTPHD2 HDMI® over Cat5 Extender Kit can extend the audio and video
signal output from an HDMI®-equipped device by up to 330 feet (100 Meters), over a
single CAT5 cable. The extender supports full High-Denition video (1080p) and HD
3D, and also extends the accompanying digital audio signal.
For convenient, time-saving control of the media source, the CAT5 HDMI extender
oers bi-directional RS232 serial and Infrared (IR) interfaces, which enable you to
control the HDMI audio-video source from either end of the connection.
The HDMI over CAT5 Extender Kit includes both the HDMI® to CAT5 transmitter and the
Cat5 to HDMI receiver needed for a cost-eective, ready-to-use digital signage solution.
To help ensure seamless performance without any unexpected or unnecessary
interruptions, the HDMI Ethernet transmitter and receiver units are fully compliant
with High Speed HDMI® and HDCP standards, and each unit features lockable power
connectors to prevent accidental disconnections.
The ST121UTPHD2 HDMI over Cat5 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.
Notes: Ensure the Extender 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 the provided 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 ST121UTPHD2 to extend an infrared (IR) device signal.
Connect the IR Transmitter Cable to the IR OUT 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.
e) (Optional) If you would like to use a local display, connect an HDMI® cable (Not
provided) from the display to HDMI® bypass.
Note: Only the local or remote display can work at one time. Connecting a display to
the HDMI® bypass will result in the remote display losing signal.
f) (Optional) If also transmitting RS232 signals over Cat5, connect the transmitting
RS232 device to the“RS232” connector on the Transmitter Unit using a DB9 cable
(Not included).

2. Install RJ45 terminated Cat5 Ethernet Cable
a) Connect an RJ45 terminated Cat5 Ethernet cable (not included) to the RJ45
connector on the Transmitter unit.
Note: If you are using surface cabling, ensure you have enough Category 5 unshielded
twisted pair (UTP) network cabling to connect the Host Unit to the Remote Unit’s
location, and that each end is terminated with a RJ45 connector. The cabling should
not go through any networking equipment (i.e. router, switch).
OR
If you are using premises cabling, ensure that the Category 5 unshielded twisted pair
(UTP) network cabling between the Host Unit and the Remote Unit has been properly
terminated in a wall outlet in each location and there is a patch cable long enough
to connect the Remote Unit and the Host Unit to their respective outlets. The cabling
should not go through any networking equipment (i.e. router, switch).
b) Connect the other end of the Cat5 cable run to the RJ45 connector on the
Receiver Unit.
3. Install Receiver Unit
a) Position the Receiver Unit near the video display (i.e. television, projector).
b) Connect the video source to the HDMI® OUT on the Receiver Unit using an
HDMI® cable (Not included).
c) (Optional) If using the ST121UTPHD2 to extend an infrared (IR) device signal.
Connect the IR Receiver Cable to the IR IN 1 on the Receiver Unit, and Position
the IR sensor where the remote control will point.
Note: If you intend to point the remote control directly at the Receiver Unit, the IR
Receiver cable is not required, as IR IN 2 is physically embedded into the device.
g) (Optional) If also transmitting RS232 signals over Cat5, connect the receiving
RS232 device to the“RS232” connector on the Receiver Unit using a DB9 cable
(Not included).
d) Connect the provided Receiver Unit power supply. The Power LED will light, and
LINK & HDCP LEDs will turn on after a successful connection between both units
is established. This may take several seconds.
4. Your source video image will now appear on the remote video display.
