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.
or
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.
