Installation
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: This HDMI® extender kit features Power over cable, allowing both the
transmitter and Receiver to be powered from a single power source that can be
connected at either end of the connection. Please ensure that either the Transmitter
or the Receiver Unit is 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

provided power supply.
2. Install RJ45 terminated Cat5e/6 Ethernet Cable
a) Connect an RJ45 terminated Cat5e/6 Ethernet cable (not included) to the RJ45
connector on the Transmitter unit.
NOTE:
If you are using surface cabling, ensure you have enough Category 5e unshielded
twisted pair (UTP) network cabling to connect the Transmitter Unit to the Receiver
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 Transmitter Unit and the Receiver Unit has been
properly terminated in a wall outlet in each location and there is a patch cable long
enough to connect the Receiver Unit and the Transmitter 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 Cat5e/6 cable run to the RJ45 connector on the
Receiver Unit.
