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.

transmitter and Receiver to be powered from a single power source that connects
to either the transmitter or receiver unit. Please ensure that unit you’ve chosen to
power is situated near an available AC electrical outlet. Make sure all devices are
turned o before beginning installation.
Before you begin Hardware Installation ensure both Transmitter and Receiver are
properly grounded.
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 port on the Transmitter Unit.
c) (Optional) If you’ve chosen to connect the power adapter to the transmitter unit,
connect the power adapter from the power adapter port to an available wall outlet.
d) (Optional) If using the Extender to extend up to three 10/100 Network signal(s),
connect up to three Ethernet cable(s) from the Network gateway to the LAN Port(s)
on the Transmitter Unit.
e) (Optional) If using the Extender kit to transmit an infrared (IR) device signal, and
the device receiving the IR signal is on the Receiver side. Connect the IR Transmitter
Cable to the IR-RX port on the Transmitter Unit, and position the extended IR sensor
directly in front of the video source’s IR sensor. Check the manual of your video
source device for the IR sensor location. If the device receiving the IR signal is on
the Transmitter side, and connect the IR Transmitter Cable to the IR-TX port, and
position the IR sensor where the remote control will point.

unshielded twisted pair (UTP) network cabling to connect the Host Unit to the
Remote 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 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 Cat5e/6 cable run to the RJ45 connector on the
Receiver Unit.
3. Install Receiver Unit
a) Position the Receiver Unit near the video display (i.e. television, projector).
b) Connect the Display to the HDMI out port on the Receiver unit using an HDMI cable.
c) (Optional) If you’ve chosen to connect the power adapter to the Receiver unit,
connect the power adapter from the power adapter port to an available wall outlet.
d) (Optional) If using the Extender to extend up to three 10/100 Network signal(s),
connect up to three Ethernet cable(s) from the LAN Port(s) on the Receiver Unit to
RJ-45 port on your network device(s).
