be located and set up the device. Ensure this is near an electrical box with 2x
terminated RJ45 connectors leading to the remote display.
2. Determine where the remote display will be located and place/mount the display
appropriately. Ensure this is near an electrical box with 2x terminated RJ45
connectors leading to the local video source.
Note: This HDMI extender kit features Power Over Cable, allowing both the transmitter
and receiver to be powered from a single power source that connects to either the
transmitter or receiver unit. Please ensure that the unit you’ve chosen to power
is situated near an available AC electrical outlet, or a DC terminal power source is
available in the electrical box for the transmitter or receiver unit. Make sure all devices
are turned o before beginning installation. Before you begin Hardware Installation
ensure both transmitter and receiver are properly grounded.

Hardware Installation
1. Install the RJ45 terminated Cat5e/6 Ethernet cables to the transmitter and
receiver units.
a) Connect two RJ45 terminated Cat5e/6 Ethernet cables (not included) to the
transmitter unit - one cable for the Link Out 1 RJ45 connector and another one for
the Link Out 2 RJ45 connector.
Note: Ensure that the Category 5/6 unshielded twisted pair (UTP) network cabling
between the transmitter unit and the receiver unit has been properly terminated in
a wall box in each location. Also, ensure that the patch cables are long enough to
connect the transmitter unit and the receiver unit inside their respective electrical
boxes. The cabling should not go through any networking equipment (i.e. router,
switch).
b) Connect the other ends of your terminated Cat5e/6 cable runs to the Link Out 1
and Link Out 2 RJ-45 connectors on the receiver unit.
2. Connect the power source to the transmitter or receiver unit.
Note: The HDMI extender kit only requires a single power source to be connected to
either the transmitter or receiver unit.
There are two methods for providing power to the HDMI extender kit. Please review
each method below and determine your desired method.
a) Method 1 – Using the included power adapter.
Note: If you’ve chosen Method 1 please complete step 3. (Install the extender and
receiver units into the electrical boxes) before connecting your power source.
i. Determine whether you will be connecting your power source to either the
transmitter or the receiver unit.
ii. Using the included power adapter, connect the power adapter port on either
the transmitter or receiver unit to an available wall outlet.
b) Method 2 – Using terminal DC power.
i. Determine whether you will be connecting your power source to either the
