Introduction
The ST12MHDDC HDMI® to CAT5 Extender kit lets you extend an HDMI® audio and
video signal over a single Cat5 or Cat6 cable up to 330 feet (100 meters). The extender
oers a highly scalable installation when used with the optional ST12MHDDCRP
repeater units, which can be daisy-chained to additional displays at greater distances.
Using ST12MHDDCRP repeater units (sold separately), you also have the option to
daisy-chain the HDMI® over Cat 5/6 up to 30 broadcasting levels to over 100 displays.
With 2 RJ45 to HDMI® output ports per unit, each repeater allows you to output to a
display - and also extend the HDMI® signal to 2 additional HDMI® repeaters at up to
an additional 330 feet (100 meters) at each level, making this the perfect solution for
large-scale digital signage applications that require maximum HDMI® signal quality.
For further scalability, the ST12MHDDC kit can be used with existing network cable
for a cost-eective and exible extension. Plus, because the HDMI® signal is extended
over standard Cat5/Cat6 Ethernet cable with RJ45 connectors, proprietary cables aren’t
necessary which eliminates both expense and the hassle of running specialized cable.
The HDMI® over Ethernet Extender kit includes optional mounting hardware and
features an HDMI® output on the local transmitter unit, which allows you to keep a
display or projector near your video source.
Ideal for High-Denition applications, the HDMI® over UTP extender supports 1080p
video resolutions, 7.1 digital audio and features built-in EDID monitor emulation,
which ensures native resolution and maximum compatibility with your display or
projector, for a convenient plug-and-play installation.
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(s) will be located and place/ mount the display
appropriately.
3. (Optional) If using ST12MHDDCRP Repeater unit(s) (sold separately), determine
where the remote display will be located in relation to the other displays and place/
mount the display(s) appropriately. Repeaters allow for an additional 330 ft. (100
meters) of Cat5/6 between each device. The repeater(s) must be situated between
the extender and the receiver, as the receiver does not have an RJ45 out port to
continue the chain.
NOTE: Ensure the Transmitter Unit, the Receiver Unit, and any Repeater Units are all
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.
2. Install RJ-45 terminated Cat5/6 Ethernet Cable
a) Connect an RJ-45 terminated Cat5/6 Ethernet cable to the HDMI® Out Link (RJ-45
Connector) on the Transmitter unit.
NOTE: If you are using surface cabling, ensure you have enough Category 5/6
unshielded twisted pair (UTP) network cabling to connect the Transmitter Unit to
the Remote Unit’s (Repeater/Receiver) 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 5/6 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 Cat5/6 cable run to the RJ45 connector on the
remote Unit (Receiver/Repeater) Unit.
c) (optional) When adding multiple repeaters, a run of Cat 5/6 cable will be required
from and to each device.

3. (Optional) Install Repeater Unit(s) (sold separately)
a) Position the Repeater Unit near the video display (i.e. television, projector) within
330 ft. (100 meters) from the level up device be it the initial transmitter or
another repeater.
b) Connect the video source to the HDMI® Out on the Repeater Unit using an
HDMI® cable.
c) Connect the Cat5/6 cable positioned in Step 2 to the”HDMI® In Link (RJ-45
Connector)” on the Repeater. Connect the Receiver Unit power supply. The Power
LED will light, and LINK LED will turn on after a successful connection between both
units is established. This may take several seconds.
NOTE: These steps can be repeated at each level when adding additional Repeaters
up to 30 levels. Each Repeater has two HDMI® out Links (RJ-45 Connectors) allowing
for the same signal to go in 2 dierent directions at each level.
4. Install Receiver Unit
d) Position the Receiver Unit near the video display (i.e. television, projector) within
330 ft. (100 meters) from the level up device be it the initial transmitter or
another repeater.
e) Connect the video source to the HDMI® out on the Receiver Unit using an
HDMI® cable.
f) Connect the provided Receiver Unit power supply. The Power LED will light,
and Link LED will turn on after a successful connection between both units is
established. This may take several seconds.
NOTE: The Receiver should only be used as the last device in the chain as it does not
have an HDMI out port (RJ-45 Connector).
5. Your source video image will now appear on the remote unit(s) attached
video display.
