The perfect complement for a Wi-Fi connection
Powerline adapters are the ideal way of creating a home network or
complementing an existing Wi-Fi connection.
By providing a secure high speed connection and great service quality,
Powerlines allow you to watch Standard and High Denition (HD)
movies as well as play online games without interruption or pixilation;
share photos, music and other media stored on a PC or compatible
storage device anywhere in your home.
Powerline Adapters will help you reach those areas of your home where
Wi-Fi signal is either too weak or cannot reach.
Other usages of Powerline adapters include IP-CCtv surveillance
cameras, setting up an ofce network without the need to add more
wires or rewire if you change your ofce conguration.

Ethernet Port:
Powerlines use an Ethernet port to connect
through an Ethernet cable to the device you
wish to add to your network. One end of the
Ethernet cable is connected to the Powerline
adapter, while the other end is connected to
your device.
Front and rear plugs
Comtrend Powerline adapters are the rst ones in the UK market to
bring a fully BS1363 certied female plug; so choosing a Comtrend
Powerline PG902 means you can still safely use your electrical outlet.

How to install the PowerGrid 902
Comtrend’s PG902 starter kit, supplied in pairs, comes ready to use;
the Powerline adapters are paired in our factory so they will recognize
each other, which makes setup this easy:
1. Plug both PG902 adapters into an electrical socket
a. One next your router (or modem)
b. One next to the device you will connect to your network
2. The Status LEDs on both PG902 adapters will light up RED
3. When the Status LEDs are both GREEN the adapters are ready
to use
Pick the PG902 adapter with a serial number ending with the letter “A”.
The serial number can be found on the label at the back of the adapter.
This is the Access Point (AP). Connect the AP to your router with an
Ethernet cable, as shown here.
Connect the other PG902 to your computer, V-box or other network
device using an Ethernet cable. This is the End Point (EP).

Shortly, you will see the Ethernet LED blinking; this indicates that there
is data trafc going through the PG902. You are now ready to start
using your network.
How to use a power strip with the PG902
If you are planning to use a power strip we recommend that you plug
the power strip in to the Powerline and not the Powerline into the power
strip. If you must plug your adapter into a power strip, we suggest you
use a basic power strip as the more advanced ones have a lter that
can interfere with the Powerline signal.

How to add a new Powerline to your existing network
Comtrend Powerline pairs are paired in the factory for your convenience
and security. However if you need to add more adapters to your existing
network you will need to follow some easy steps in order to keep your
network secure. The following procedure applies to both Powerline
DH10PF and PG902 adapters.
MAKE SURE THAT ALL OF YOUR POWERLINES ARE CONNECTED
TO THE MAINS.
Step 1: Identify the current AP
(access point) adapter. From your
current adapters the one with the
AP LED in green will be the AP
adapter.
NOTE: If you performed a factory reset on the AP adapter (see step 2), it
is now an EP adapter. In this case, you will need to assign it as an
AP (see FAQ on pg. 9).
Step 2: Reset the new Adapter to its
factory settings: this is to make sure your
new adapter is set as an EP (end point).
Press the CONFIG/RESET button for
10 seconds. All LEDs will turn OFF and
the STATUS LED will be RED.

Step 3: On your AP adapter (Step 1),
press the CONFIG/RESET button until
the AP LED starts blinking.
Step 4: On the NEW EP adapter you
are adding to your network (step 2),
press the CONFIG/RESET button
until the AP LED starts ashing. The
NEW EP adapter AP LED will ash 3
times and the STATUS LED will turn
ON.
Wait until the AP LED on the AP
adapter (step 1) stops blinking.
You have now added your NEW EP adapter to your network.
Repeat the same steps for each new adapter you want to add to your
network.

How to understand the STATUS LED colours
The STATUS LED provides important information that will provide
solutions to common questions, such as why a High Denition (HD)
movie is not showing or shows with pixels. The STATUS LED indicator
will vary its colour depending on the estimated speed of the Powerline
connection. The speed is measured in Megabits Per Second (Mbps).
Colour Information
RED
The current connection is less than 4Mbps, normal internet
activities are possible but the Powerline is unable to transmit
either Standard Movies or High Denition (HD) Movies
ORANGE
The current connection is greater than 4Mbps and less than
10Mbps, normal internet activities are possible and the
network is able to transmit a single Standard Movie but not
an HD Movie.
GREEN
The current connection is greater than 10Mbps; the
Powerline is capable of transmitting Standard and HD
Movies as well as normal internet activities.
NOTE: If the HDTV video bandwidth is lower than 10Mbps, it may be pos-
sible to stream the video with an ORANGE STATUS LED in some
cases.
Frequently Asked Questions
This Powerline adapter has been designed to be a reliable and easy to
use to create or extend an existing home network. However, should
you experience any problems, please refer to the list below to aid in
troubleshooting.
1. How do I convert an AP into an EP?
• Make sure the Powerline adapter is plugged directly into the
electrical outlet and that it is powered on.
• Do a factory reset (see Step 2 on pg. 7 for the Factory Reset
procedure).
2. How do I convert an EP into an AP?
• Make sure the Powerline adapter is plugged directly into the
electrical outlet and that it is powered on.
• Press CONFIG/RESET button until its AP/STBY LED starts
blinking.
• Wait until conguration period nishes (30 seconds). At that

10
point the adapter has been designated as a Fixed AP with an
auto generated Network ID and Encryption key and its AP/
STBY LED lights GREEN.
3. Why is SDTV video not streaming?
• Check the STATUS indicator LED in the adapter connected to
the STB.
• If the indicator is RED this means that the PLC link is not able
to play an SDTV streaming.
• Try to reposition the adapter into another outlet in order to
obtain an ORANGE or GREEN indication.
• If the indicator is ORANGE or GREEN, it should now be able to
play SDTV video.
• If the SDTV video still does not play, check the Ethernet cables
and the settings of devices connected to the PLC adapters
(STB, router, PC, video server, etc.).
4. Why is there more than one AP on the network?
• In order to work properly your network can only have one Fixed
AP unit. Verify that this is the case by examining the AP/STBY
LED for all adapters
• If there is more than one AP, it means that key exchange
process has failed.
• Perform a factory reset on the adapter you DO NOT wish to
be designated as an AP (see Step 2 on page 7 for the Factory
Reset procedure).
• Repeat network conguration procedure again (page 7).
• If the conguration procedure has again failed, it is possible the
adapters are using different forms of encryption (crypto mode).
To eliminate this as a possibility;
Perform a factory reset on all adapters
Choose the adapter you will like to act as an AP (we
recommend the one connected to your modem/router)
Press CONFIG/RESET button until its AP/STBY LED starts
blinking.
Wait until conguration period nishes (30 seconds). At that
point the adapter has been designated as a Fixed AP with
an auto generated Network ID and Encryption key and its
AP/STBY LED lights GREEN.
Follow the steps on page 7 and 8.

5. Why is HDTV video not streaming?
• Check the status indicator LED in the adapter connected to the
set top box (STB).
• If the indicator is RED or ORANGE this means that the
Powerline link is not able to stream HDTV.
• Try to reposition the adapter in another outlet in order to obtain
a GREEN indication.
• If the indicator is GREEN, it should now be able to play a HDTV
video.
• If the LED is not GREEN check the Ethernet cables and the
settings of devices connected to Powerline adapters (STB, DSL
router, PC, video server, etc.).
NOTE: If the HDTV video bandwidth is lower than 10Mbps, it may be pos-
sible to stream the video with an ORANGE STATUS LED in some
cases.
6. What if my Powerline Adapters don’t t into the plug
socket?
• Your Powerline Adapters might not t because the sockets are
too close to the oor or are in the skirting board.
• The easiest way around this is to use a trailing power strip, and
plug the Adapter into the strip. Please make sure that the strip
is not an anti-surge adapter strip.
7. What if the house next door has Powerline Adapters as
well?
• Each pair of Powerline Adapters has its own unique security
key. This means that your connection is secure and cannot be
confused with anyone else’s.
8. Is it safe to leave the Powerline Adapters on all the time - is
there any danger of overheating?
• Powerline Adapters are CE certied and completely safe to
leave plugged in all the time. They may become slightly warm
in use - this is perfectly normal. However, you may wish to put
them into standby when not in use.
9. How much power do Powerline Adapters use and how much
do they cost each month in electricity?
• The Adapters use 5.5 Watts when in use and 1.8 Watts in
standby. Prices vary between electricity suppliers.

12
10. How can I check that my Powerline Adapters are working
properly?
• Your Powerline Adapters are set to work together as a pair, and
should work perfectly out of the box. The best way to test them
is to nd a double plug socket, and plug them in next to each
other. Often the best place to nd a double plug socket is in
your kitchen. Alternatively plug them into a trailing extension
strip (but not an anti-surge strip).
• When plugged in, after 10-40 seconds, the Powerline Adapters
will congure themselves so that each has a green status light,
and one of the pair has a green AP light.
• Both adapters have green status lights
• If the Powerline Adapters don’t congure themselves as above,
you need to follow the reset procedure.
• When your Powerline Adapters are connected to a device the
Ethernet light should light up. When you’re using the service
the Ethernet light will ash. You may notice that the Status Light
on one or both Powerline Adapters changes to red or orange.
This isn’t something to worry about if you are not having any
problems with your connection.
