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
oers 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-eective 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-Denition 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.
