1. Introduction
The 1080P Powerline AV Sender System DGHDP3 incorporates HDMI™
technology, allowing you to transmit HD Video anywhere in your home using
existing Power lines. This avoids the complexities of rewiring your house or buying
new Video Equipment (e.g. Video Players) for each viewing room. This system
consists of a receiver and a transmitter that deliver H.264 HD video and high
quality audio from Blu-ray™ players, Set-Top boxes, and video game consoles
(etc.) to compatible HDTV displays located near power outlets. Setup is fast and
easy; the Video Player (e.g. Blu-Ray player) is connected to your Transmitter while
your HDTV is connected to the Receiver; both Receiver and Transmitter are
connected to Power Outlets. HDMI Over PLC also allows you to use IR Remote
Controllers to control A/V equipment (stop/start/FF/Rewind etc.) remotely using IR
signals. The Transmitter and Receiver also have an additional function of
delivering Ethernet data over Power Lines, allowing you to access the Internet from
any room.

3. Troubleshooting
If no video displays on the remote TV attached to your RX, proceed with the steps
below:
Step 1: Check connections, power and equipment
Make sure all power connections are secure and power is supplied to all
equipment.
Inspect all cables and cable connections between Player-TX and TV-RX.
Make sure the Video Player is working properly and is transmitting video (hook
up a TV directly to the player to confirm). Also, make sure the TV that is
attached to the TX is in working order.
Make sure that the Source LED indicator matches the physical connection
between the TX and player that is connected to it. The LED indicators are
described in the table below.
1 HDMI connector 1
2 HDMI connector 2
3 HDMI connector 3
e.g. If you attached a Blu-Ray player to
your Transmitter using HDMI2, but your
Source LED indicator “1” is illuminated (HDMI port1), the transmitter is looking
on the wrong input connector. Simply press the Source button (see above) on
the TX until the appropriate Source LED indicator illuminates.
If video still does not display, go to Step 2.
1080P Powerline AV Sender System User Manual

Step 2: Pairing procedures for troubleshooting
“Pairing” refers to the process where two
independent systems (i.e. RX and TX)
identify themselves and establish/reestablish the link over the powerline or
Ethernet network. You can use these
procedures when troubleshooting your
system (i.e. Video fails to appear on TV
connected to the RX).
The flowchart to the right will instruct you on
how to proceed in order. The “Video
displaying?” diamond refers to video can be
displayed on the TV attached to the RX. The
procedures in the boxes are explained in the
Appendices as listed below:
Appendix 1: RX/TX Pairing
Appendix 2: Reset RX/TX to System
Defaults
It is assumed that RX, TX and video
equipment are all properly connected and
powered on.
Note: It is highly recommended that you
perform these procedures with the RX and
TX in the same vicinity, preferably attached
to the same power outlet.

7 Ethernet over PLC Function
The “Ethernet over PLC” Function allows you to deliver Ethernet data anywhere in
your home over Power Lines. This means that you can access the Internet and
browse the web from anywhere, without rewiring your entire home with Ethernet
cabling.
Both the RX and TX have LAN connectors on their rear panels. The xDSL modem,
PC/NB, Smart TV and RX connect to the Ethernet switch in RX side and the IPTV
STB or media player, other PC/NBs and TX connect to another Ethernet switch in
a separate location (as shown in the diagram above).
Note: Do not connect the LAN ports between the Receiver and the Transmitter as
it will disrupt any video streaming through the products.
8 Adding an Additional RX
You can attach up to 4 RXs to the single TX depending on your power-line
network quality. Not all power-lines are able to transmit video to multiple RXs. In
most of applications, you can only turn on 2 RXs simultaneously.
You must perform the RX-TX pairing procedures each time when you want to add
an additional RX to your system. Please refer to Appendix 1 for the detail TX/RX
pairing.
1080P Powerline AV Sender System User Manual
DGHDP3 Version 1.0 17
9 Running TX as a Standalone Box
You can use the TX in standalone mode without the RX. In other words, you can
use the TX, along with the TV and input video devices attached to it, as a
standalone system (i.e. Video Switching Box).
If both RX and TX are powered on and working, you can simply turn off the RX and
the TX becomes a standalone system.
However, if both TX and RX are initially turned off, turn on your TV and then turn
on your TX. After the TX has gone through its initialization process (20~30
seconds), you can press OK button on the remote controller to stop the LED which
is trying to link with a RX or wait for LED time out. Also you are allowed to change
the input source anytime by pressing the source button on TX (front panel) or
remote controller.
The input Source LEDs will stop blinking if the input a/v source is ready.
10 Running Multiple Transmitters
with Multiple Receivers
Each receiver (RX) can be paired with a maximum of 4 transmitters (TX) as
described in the Chapter “Adding an Additional RX”. Therefore, an HDMI Over PLC
receiver can choose from multiple transmitters as the media source. Remote
control will also be automatically redirected when changing to a different
transmitter.
