Instruction Manual

Preparing your site

1. Determine where your local video source will be located and set up the device.

2. Determine where your remote display will be located and place/ mount the display

appropriately.

Note: This HDBaseT 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 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 the installation steps, ensure both the transmitter and receiver

are properly grounded. The grounding nuts on the transmitter and receiver may be

used to do this, depending on your environment.

Installation

1. Install the transmitter

a) Position and ground the HDBaseT transmitter near your video source.

b) Connect your video source device to the HDMI in port on the transmitter.

c) (Optional) If you’ve chosen to power the HDBaseT kit using the transmitter, connect

the included power adapter to the power adapter port on the transmitter and to an

AC outlet.

d) (Optional)If you’re using the HDBaseT kit to extend an infrared (IR) signal.

If the device receiving the IR signal is at the remote side, connect the IR receiver to

the Local IR port on the transmitter, and position the IR sensor where you’ll point

your IR remote control.

If the device receiving the IR signal is at the local side, connect the IR blaster to the

Local IR port on the transmitter side, and position the IR sensor directly in front of

the video source’s IR sensor (if you’re unsure, check the manual of your video source

to determine the IR sensor location).

e) (Optional) If you’re using HDBaseT kit to transmit a serial signal, connect a serial

cable (not included) from the Local RS-232 port on the transmitter unit to the serial

port on the local device.

Instruction Manual

2. Install the receiver

a) Position and ground the HDBaseT receiver near your video source.

b) Connect your remote display to the HDMI out port on the receiver.

c) (Optional) If you’ve chosen to power the HDBaseT kit using the receiver, connect

the included power adapter to the power adapter port on the transmitter and to an

AC outlet.

d) ((Optional)If you’re using the HDBaseT kit to extend an infrared (IR) signal.

If the device receiving the IR signal is at the remote side, connect the IR blaster to

the remote IR port on the receiver, and position the IR sensor directly in front of

the device’s IR sensor (if you’re unsure, check the manual of your video source to

determine the IR sensor location).

If the device receiving the IR signal is at the local side, connect the IR receiver to the

remote IR port on the receiver, and position the IR sensor where you’ll point your IR

remote control.

e) (Optional) If you’re using the HDBaseT kit to transmit a serial signal, connect a serial

cable (not included) from the Remote RS232 port on the receiver to the serial port

on the remote device.

3. Install RJ-45 terminated CAT5e/6/7 Cable

a) Connect an RJ-45 terminated CAT5e/6/7 cable (sold separately) to the Link port on

the transmitter.

b) Connect the other end of the RJ-45 terminated CAT5e/6/7 cable (not included) to

the Link port on the receiver.

Notes:

• The cabling should not go through any networking equipment (i.e. router, switch)

• If you are using surface cabling, ensure you leave enough cabling to connect the

transmitter to the receiver, and that each end is terminated with an RJ-45 connector.

The cabling should not go through any networking equipment (i.e. router, switch).

• If you are using premises cabling, ensure that the cabling between the transmitter

and receiver has been properly terminated in a wall-outlet at each location and

there is a patch cable long enough to connect the transmitter and receiver to their

respective wall-outlet.

4. Power on your video source and your display and the source image will now

appear on the remote video display.
