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 connects
to the transmitter unit. Please ensure that the Transmitter 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
Player) to the “HDMI® IN” on the Transmitter Unit.
c) Connect the power supply.
d) (Optional) If using the Extender to extend one or two 10/100 Network signal(s),
connect the Ethernet cable(s) from the Network gateway to the 100Base-T IN 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

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 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 video source to the HDMI® OUT on the Receiver Unit using an HDMI®
cable.
c) (Optional) If using the Extender to extend one or two 10/100 Network signal(s),
connect the Ethernet cable(s) from the 100Base-T OUT Port(s) on the Receiver Unit
to RJ-45 port on your network device(s).
d) (Optional) If using the Extender kit to transmit an infrared (IR) device signal,
and the device receiving the IR signal is on the Transmitter side. Connect the IR
Transmitter Cable to the IR-TX port on the Receiver Unit, and position the IR sensor
where the remote control will point. 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 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.
