Preface
Thank you for placing your trust in this devolo product.
The dLAN adapters are compatible to the HomePlug standard and enable you
to establish or expand a home network easily and economically. PC work such
as data exchange, accessing a network printer over the home network or
Internet access is all done over the existing electrical wiring in the building.
A dLAN adapter turns every power outlet into a network connection. You are
completely independent—use a power outlet anywhere from the basement
to the attic.

1 Introduction
This chapter gives you an overview of the new dLAN technology and a brief
introduction to the two devolo dLAN adapters.
1.1 What exactly is dLAN?
There is now a new alternative to the well-known wired LAN and Wireless
LAN network technologies currently used in home networking: dLAN (direct
LAN, i.e. directly networked). dLAN is home networking using the electric
wiring already installed in the building.
Cost factor and transmission quality
dLAN is an economical and easy-to-use networking technology. You don't
need to lay cables and you can connect to the home network at every power
point.
The dLAN technology modulates and demodulates additional frequencies on
the power lines. Modulation and demodulation is a well-known and proven
method of data transmission, which has been in use in other applications for
a number of years. Now it is used to set up Internet and network accesses in
the home or office. Depending on the damping factor, distances of up to 200
meters can be covered.
With a maximum data transmission rate of 14 Mbps and symmetrical upload
and download, the dLAN technology is equivalent to classical Ethernet net-
working solutions and is faster than the current wireless standard WIFITM for
home applications. Depending on the line quality, bandwidths of 6 to 8 Mbps
are possible in practice—quite sufficient for extending the DSL connection
to all rooms.
Data security and radiation
The power meter in the building acts as a physical barrier against unwanted
access from outside. However, for the sake of security, software-activated
56-bit encryption should be used to guarantee secure data transfer within the
network.
dLAN devices from devolo meet the stringent EU industrial standards and
comply with the current standards for electromagnetic radiation. In fact, the
radiation is distinctly lower compared to wireless LAN technologies.

1.2 What does the dLAN adapters from devolo offer
you?
The dLAN adapters from devolo enable you to set up or expand a home net-
work easily and economically. PC work such as data exchange, accessing a
network printer over the home network or Internet access is all done over the
existing electrical wiring in the building. A dLAN adapter converts every
power point into a connection to your home network. You are completely
independent—use a power outlet anywhere from the basement to the attic.
And the advantages of computer networking at home or in the office are obvi-
ous:
Common usage of one Internet access
(e.g. Internet-DSL connection)
Common usage of one printer
Common access to centrally stored data
Multi-user games over the network.
You can find examples of possible networks and general information in the
chapter 'All about home networking'.
1.2.1 MicroLink dLAN Ethernet
Simple installation
Connect the MicroLink dLAN Ethernet to the computer or the device with
the Ethernet cable
Connect the MicroLink dLAN Ethernet to the power outlet
Install the devolo tools MicroLink dLAN Configuration Wizard and
MicroLink Informer
Done!
Ethernet connection
The MicroLink dLAN Ethernet adapter has an Ethernet port for connecting to
a device in the home network (e.g. PC, notebook, modem, router, switch etc.)
and it has a standard power plug for connection to a power outlet. The
adapter is powered by an integrated 230V AC power supply.

|Introduction 9

Status display
The indicator lights (LEDs) of your MicroLink dLAN Ethernet adapter show the
connection status, allow the data transmission to be checked and make it
easy to diagnose any system malfunctions. The MicroLink dLAN Ethernet
adapter has 4 indicator lights and an Ethernet port.
1.2.2 MicroLink dLAN USB
Simple installation
Connect the MicroLink dLAN USB to the computer with the USB cable
Connect MicroLink dLAN USB to the power outlet
Install the devolo drivers
Install the devolo tools MicroLink dLAN Configuration Wizard and
MicroLink Informer
Done!
USB port
The MicroLink dLAN USB adapter has a USB output for connection to a com-
puter in the home network with a USB port. The USB port makes the
MicroLink dLAN USB adapter independent of power from an external power
adapter.
Status display
The indicator lights (LEDs) of your MicroLink dLAN USB adapter show the
connection status, allow the data transmission to be checked and make it
easy to diagnose any system malfunctions. The MicroLink dLAN USB adapter
has 3 indicator lights and a USB port.

3 All about the home network
This chapter contains important and useful information on networks—from
the configuration of your computer to examples of applications to general
tips.
3.1 Configuring the computer
Now that you have successfully connected and installed your devolo dLAN
adapter, we show you how to configure your computer correctly and how to
check existing settings.
3.1.1 Windows 98 and Windows Me
햲Open the properties of the LAN connection on the connected computers
by selecting Start  Settings  Control Panel  Network.
햳Click the entry for the TCP/IP protocol of the network adapter and on
Properties. Enable the option 'Obtain an IP address automatically'. You
can ignore all other options: they either remain empty or retain their
default settings. Close the dialogs with OK.
If you cannot find an entry similar to 'TCP/IP' or 'TCP/IP -> Network Adapter
Name' or 'Internet Protocol (TCP/IP)', you must install the TCP/IP protocol.
Under Add select 'Protocol' and click Add again. In the next dialog box under
'Manufacturer' select 'Microsoft' and under 'Network Protocol' select 'TCP/
IP'.
햴If you use a router for Internet access, you will still need to configure it,
because the router dials into the Internet, not the computer. Under Start
 Settings  Control Panel  Internet Options select the 'Connec-
tions' tab and enable the 'Never dial a connection' option. Close the dia-
logs with OK.
3.1.2 Windows 2000
햲Open the properties of the LAN connection on the connected computers
by selecting Start  Settings  Control Panel  Network and
Dial-up Connections. Click with the right mouse button on the corre-
sponding LAN connection and select 'Properties'.

3.3 Worth knowing
Network volume
The maximum number of dLAN adapters in a single-family house is theoreti-
cally 253 connections, but in practice no more than 10 devices should be
transferring data simultaneously.
Compatibility
The devolo dLAN adapters are compatible to all other devolo LAN products,
to all devices that comply with the IEEE 802.3 standard and to other Home-
Plug devices.
Network security
Normally the electric meter forms a physical barrier, i.e. only devices con-
nected to this meter can be part of the network and benefit from the phase
coupling. We strongly recommend that you use the dLAN adapter's internal
device encryption. It is configured with the MicroLink dLAN Configuration
Wizard. For more information see the 'devolo tools' chapter.
