2Introduction
dLAN is an intelligent, secure technology that lets you
set up a home network easily, quickly and economical-
ly via your household electrical wiring, without the
need for complex and expensive dedicated cabling.
devolo dLAN 550 duo+
10 Introduction
2.1 What exactly is dLAN?
dLAN (direct Local Area Network) uses the household
power grid to transfer data between computers
equipped with suitable adapters and other network
components. As a result, any power outlet can be used
as a network access point. The data is modulated prior
to transfer and sent as a signal via household power
lines. State-of-the-art technology ensures that the
power and data networks do not interfere with one another. Networking via dLAN is fast and secure. The
data is encrypted using a key to prevent interception by
third parties.
2.2 devolo—Up to speed on green IT
The topic everyone is talking about is green IT. devolo
has an easy solution: the power saving mode, which
comes standard with the home network adapters, sets
the company apart from many competitors in the IT industry.
Developers at devolo, have for a long time kept a close
eye on how much power dLAN adapters may consume.
After all, a devolo network via electrical sockets should
not only be convenient, but also require as little energy
as possible—particularly during times when it is not
being used.
That devolo can satisfy the demand for energy efficiency is evidenced by the patented power saving mode
in the devices. It automatically reduces the energy
consumption when the computers in the dLAN network or connected equipment are switched off.
The power saving mode in the adapters is not only a tribute to environmental protection but also a real
service to the customer. Most people tend to forget to
regularly press the standby button on the hardware.
The patented technology in devolo adapters allows you to save energy without having to do
anything. And if less energy is consumed, your elec-
tric meter will turn more slowly. In other words, every
minute the adapter is in power saving mode, you will
save money.
devolo dLAN 550 duo+
Introduction 11
A dLAN adapter connected to a computer can only go into power saving
mode if the network card of the switched-off computer is also inactive. If
you are using a network card that remains active even when the computer is switched off, we recommend
connecting the computer to an on/off
switch using a multiple socket so that
both the computer and the integrated network card are de-energised.
2.3 dLAN 550 duo+
쎲 Your home network from the power socket.
Unpack. Plug it in. Get started. The easy way to
connect using your home's power lines. Turn any

쎲 The fast transfer rate and dLAN speeds up to
500 Mbps allow you to experience entertainment
at the highest level. The range+ technology
provides an even more stable Internet connection
with significantly longer range.
쎲 The "Quality of Service" function and transfer
rates of up to 500 Mbps are enough for bandwidth-hungry applications. Automatic data prior-
itisation ensures interference-free reproduction of
voice and video data.
쎲 The integrated electrical socket enables additional
terminal devices or multiple sockets to be connected to the adapter just as a normal wall
socket—no power supply is lost.
쎲 The two Fast Ethernet LAN ports allow you to con-
nect two Internet-compatible devices (e.g. a game
console, television or media receiver) to the Internet at any time via network cable.

4.1 Security in the dLAN
Before you can use the dLAN 550 duo+ in your dLAN
network, first you have to connect it to other dLAN devices as a home network. Two specific pieces of information are especially important for this:
쎲 Shared use of a dLAN password results in a delim-
ited dLAN network.
쎲 Shared use of the dLAN password serves as access
control to the dLAN network as well as the
encryption, and thereby the interception protection, of the transmitted data.
The dLAN password can be set in different ways:
쎲 Automatically using the encryption button (see
4.2 dLAN network encryption at the touch
of a button)
쎲 Manually using the devolo Cockpit program
(see 4.3 devolo Cockpit).
4.2 dLAN network encryption at the touch of a button

4.3.1 Encrypting a network with
devolo Cockpit
If you use dLAN devices without an encryption button, data can be encrypted only via devolo Cockpit.
Before the networking procedure,
note the security IDs of all dLAN adapters. This unique identifier of each
dLAN device is located on the label
on the housing. It consists of 4 x 4 letters separated by dashes (e.g. ANJRKMOR-KSHT-QRUV). Ensure that all
dLAN adapters are connected to the
power grid and computers or other
network components as appropriate.
Scan for local adapter
After devolo Cockpit is started, it searches for the dLAN
adapter connected directly to your computer first.
Adding an adapter
Add all the dLAN devices you want to your dLAN
network by selecting the Add adapter button. You
will need the 16-character security IDs of the adapters
from the label on the housing. Enter it now in the
Security ID field and confirm with OK. If a security ID
is correct and the device can be reached in the dLAN
network, it will be added to your network of configured
adapters and also displayed in the program.
Entering a network password
After you have added all the dLAN devices you want to
your dLAN network, select the Change password
button to assign a shared network password that will
apply for all registered adapters in your personal home
network.
You can choose between your own password, a random password and the default password. To define
your own password with a length of at least eight characters, enter this into the Network password text
field. Alternatively, you can have a randomly selected,
highly secure password assigned using the Generate
secure password button. Use the Factory default
password button to reset the dLAN adapter to the de-
fault password. Normally, the display of the password
is hidden for security reasons. If you enable the option
Show characters, the current password is displayed
in legible form in the text field.
The factory default password is
HomePlugAV. Assigning a specific
password to a single adapter will
exclude it from the remaining dLAN
network.
If devolo Cockpit is called up again later after a successful initial installation, for example to integrate a
new adapter into a network, the application remem-

bers the devices that were entered earlier. Enter the
new device as described in the Adding an adapter
section. The current network password is assigned
automatically to the newly added device.

5.1 Bandwidth optimization
To significantly improve the transmission capacity of
the network, we recommend that you comply with the
following "connection rules":
쎲 Plug the device directly into a wall socket. Avoid
multiple sockets.
쎲 You should connect all additional network devices
that are connected to a multiple socket to the
mains power supply via the electrical socket integrated into the dLAN 550 duo+.
쎲 To take full advantage of the filter function of the
dLAN 550 duo+ and to improve data transmission
in the network, always plug the multiple socket
into the electrical socket of the dLAN 550 duo+.
5.2 Disposal of old devices
To be used in the countries of the European Union and
other European countries with a separate collecting system:
The icon with crossed-out wastebasket on
the device means that this adapter is an
electrical or electronic device that falls
within the scope of application of the
European Community WEEE Directive.
These types of devices may no longer be
disposed of with household waste. Rather
they can be given to a municipal collection
point free of charge. Contact your
municipal government to find out the
address and hours of the nearest collection
point.

5.3 Warranty conditions
The devolo AG warranty is given to purchasers of devolo products in
addition to the warranty conditions provided by law and in accordance with the following conditions:
1 Warranty coverage
a) The warranty covers the equipment delivered and all its parts.
Parts will, at devolo's sole discretion, be replaced or repaired
free of charge if, despite proven proper handling and adherence to the operating instructions, these parts became defective due to fabrication and/or material defects. Alternatively,
devolo reserves the right to replace the defective product with
a comparable product with the same specifications and features. Operating manuals and possibly supplied software are
excluded from the warranty.
b) Material and service charges shall be covered by devolo, but
not shipping and handling costs involved in transport from the
buyer to the service station and/or to devolo.
c) Replaced parts become property of devolo.
d) devolo is authorized to carry out technical changes (e.g. firm-
ware updates) beyond repair and replacement of defective
parts in order to bring the equipment up to the current technical state. This does not result in any additional charge for the
customer. A legal claim to this service does not exist.
2 Warranty period
The warranty period for this devolo product is three years. This
period begins at the day of delivery from the devolo dealer. Warranty services carried out by devolo do not result in an extension of
the warranty period nor do they initiate a new warranty period. The
warranty period for installed replacement parts ends with the warranty period of the device as a whole.
3Warranty procedure
a) If defects appear during the warranty period, the warranty
claims must be made immediately, at the latest within a period
of 7 days.
b) In the case of any externally visible damage arising from trans-
port (e.g. damage to the housing), the person carrying out the
transportation and the sender should be informed immediately. On discovery of damage which is not externally visible,
the transport company and the sender are to be immediately
informed in writing, at the latest within 3 days of delivery.
c) Transport to and from the location where the warranty claim is
accepted and/or the repaired device is exchanged, is at the
purchaser's own risk and cost.
d) Warranty claims are only valid if a copy of the original pur-
chase receipt is returned with the device. devolo reserves the
right to require the submission of the original purchase receipt.
4 Suspension of the warranty
All warranty claims will be deemed invalid
a) if the label with the serial number has been removed from the
device,
b) if the device is damaged or destroyed as a result of acts of
nature or by environmental influences (moisture, electric
shock, dust, etc.),
c) if the device was stored or operated under conditions not in
compliance with the technical specifications,
d) if the damage occurred due to incorrect handling, especially to
non-observance of the system description and the operating
instructions,
e) if the device was opened, repaired or modified by persons not
contracted by devolo,
f) if the device shows any kind of mechanical damage, or
g) if the warranty claim has not been reported in accordance with
3a) or 3b).

5Operating mistakes
If it becomes apparent that the reported malfunction of the device
has been caused by unsuitable hardware, software, installation or
operation, devolo reserves the right to charge the purchaser for the
resulting testing costs.
6 Additional regulations
The above conditions define the complete scope of devolo's legal
liability.
a) The warranty gives no entitlement to additional claims, such as
any refund in full or in part. Compensation claims, regardless
of the legal basis, are excluded. This does not apply if e.g.
injury to persons or damage to private property are specifically
covered by the product liability law, or in cases of intentional
act or culpable negligence.
b) Claims for compensation of lost profits, indirect or consequen-
tial detriments, are excluded.
c) devolo is not liable for lost data or retrieval of lost data in
cases of slight and ordinary negligence.
d) In the case that the intentional or culpable negligence of
devolo employees has caused a loss of data, devolo will be liable for those costs typical to the recovery of data where periodic security data back-ups have been made.
e) The warranty is valid only for the first purchaser and is not
transferable.
f) The court of jurisdiction is located in Aachen, Germany in the
case that the purchaser is a merchant. If the purchaser does
not have a court of jurisdiction in the Federal Republic of Germany or if he moves his domicile out of Germany after conclusion of the contract, devolo's court of jurisdiction applies. This
is also applicable if the purchaser's domicile is not known at
the time of institution of proceedings.
g) The law of the Federal Republic of Germany is applicable. The
UN commercial law does not apply to dealings between devolo
and the purchaser.
