Introduction
The ST12MHDDCRP HDMI® to CAT5 Repeater works with the ST12MHDDC HDMI®
Extender Kit to add additional displays and extend the HDMI® over Cat 5/6 signal. With
2 RJ45 outputs per unit, each repeater allows you to add a display, and also daisy-chain
the signal to 2 additional ST12MHDDCRP repeaters (sold separately) at up to 330 feet
(100 meters) at each level.
Additional repeaters can be added at any time, up to a maximum of 30 broadcasting
levels to over 100 displays - allowing for a highly scalable installation that can be used
with existing network cable for a cost-eective and exible extension. Each repeater
includes mounting hardware for a clean and professional installation. 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.
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
NOTE: This device will only work with the ST12MHDDC HDMI Extender kit. Please
review site preparation steps from the ST12MHDDC manual prior to installing
additional Repeaters.
1. Determine where the Repeater/Display will be installed in relation to the
ST12MHDDC HDMI Extender kit (sold separately) and place/mount the display
appropriately.
2. (Optional) If using additional repeater unit(s) (sold separately), determine where
the remote display(s) will be located in relation to this repeater/display 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 ST121MHDDC extender and the receiver, as the receiver portion does not have
an RJ-45 out port to continue the chain.
NOTE: Ensure the Repeater Unit(s) are situated near an available AC electrical outlet.
Make sure all devices are turned o before beginning installation.

Hardware Installation
NOTE: This device will only work with the ST12MHDDC HDMI® Extender kit. Please
review the Hardware Installation steps from the ST12MHDDC manual prior to installing
additional Repeaters.
1. 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 local Unit (Transmitter or Repeater).
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
Repeater unit.
c) (optional) When adding multiple repeaters, a run of Cat 5/6 cable will be
required from and to each device.
2. Install Repeater Unit(s)
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 1 to the”HDMI® In Link (RJ-45
Connector)” on the Repeater. Connect the Repeater 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.
3. 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 ST12MHDDC receiver (sold separately) should only be used as the last
device in the chain as it does not have an HDMI® out port (RJ-45 Connector).
4. Your source video image will now appear on the Repeater unit(s) attached
video display.
