Powerline Adapter PL500D N150
1 Introduction
This chapter gives an overview of the Powerline technology and briefly intro-
duces the adapter. Practical examples are listed at the end of the chapter.
1.1 What does “Inhouse Powerline” stand for?
HomePlug (“Inhouse Powerline”, PLC) is an intelligent, secure technology
thatletsyousetupahomenetworkeasily,quicklyandeconomicallyviayour
electrical wiring, without the need for complex and expensive dedicated
cabling.Theavailableperformanceandeffortrequiredfortheinstallationalso
compares favourably to traditional methods—Powerline technology now
attains speeds you would expect from other LAN technologies.
1.2 What is WLAN?
WLAN(Wireless LocalAreaNetwork) referstotheuseofradiotechnologyto
network computers and other devices. While it is possible to wirelessly con-
nectcomputersinpairs(peer-to-peer,p2p),acentralaccesspointisrequired
to set up a network of multiple devices. Such access points are frequently
combined in a single device with modems for Internet access and routers to
manage network traffic.
Thewirelessnetworkestablishedbyanaccesspointusingaspecificchannel
(from1to13) and name(SSID)hasalimitedrange.Therange of the access
point, which is also known as a "radio cell", is impeded by building walls. In
some cases, stable connections are often only possible between WLAN
devices within a single room.
Asitis not possibletorelyon hardware suchasnetworkcables (in aLAN)or
household wiring (in Powerline) to control access to a WLAN, wireless net-
workingnaturallypresentsspecialsecuritychallenges.WLANsthereforeuse
a number of security measures, such as a concealed network name, data
encryption and access control via the MAC addressesof the network adapt-
ers.
1.2.1 Wi-Fi or WLAN?
Wi-Fi is an inventedbrand name of the Wi-Fi Alliance, a consortium that cer-
tifies devices with wireless interfaces. In many countries, Wi-Fi is also used

synonymously with WLAN, which if taken strictly, is incorrect, because Wi-Fi
designates the wireless standard and WLAN the wireless network.
1.3 The PL500D N150
With the PL500D N150 you can quickly and easily establish connections
between WLAN, HomePlug (PLC) and LAN.
• As a WLAN access point, the adapter establishes communication between
your WLAN devices and an existing LAN or PLC network. In this way, for
example, you can expand your wireless network in no time to rooms that
otherwise could not be reached by wireless.
• As a PLC device, the PL500D N150 has one LAN jack for directly connect-
ing a network device to the power lines.
• By combining the LAN, HomePlug and WLAN standards, you will become
totallyindependentofexistingnetworkaccesspoints.Instead,youarecom-
pletely free to connect all your devices either via a power supply socket,
LAN or wirelessly. With WiFi Sync, you have optimal Wi-Fi reception for
smartphones,laptops andtablets in the entire home—completely automat-
ically (at least two PL500D N150 required).
• Automatic encryption! Protection from unauthorised access at thetouch of
a button for Wi-Fi (WPS) and HomePlug (AES)
• You can operate up to 8 adapters within one network.
1.3.1 WiFi Sync
WiFiSync isafunction ofthe PL500D N150forautomatic synchronisation of
the entire Wi-Fi settings of all PL500D N150 adapters connected to your
home network. WiFi Sync is activated easily at the touch of a button on the
adapter. For more information, refer to Chapter 'Quickstart' and 'Network
configuration'.

Powerline Adapter PL500D N150
WiFi Sync
Thanks to WiFi Sync, an automatic synchronisation of the Wi-Fi settings
takes place between all PL500D N150 adapters, freeing youof the hassle of
configuring of each individual PL500D N150.

Quickstart 9
Powerline Adapter PL500D N150
2 Quickstart
2.1 System requirements
• Operating systems:WindowsVistaHomePremium(32bit/64bit),Windows
7 (32 bit/64 bit), Windows 8 (32 bit/64 bit), Windows 8 Pro (32 bit/64 bit) or
any other operating system with network support
• Network connection
Please note that your computer or other device must feature a network
adapter with a network port. To set up a PLC network, you need at least two
PLC devices (200 Mbps or 500 Mbps).
2.2 Connecting the PL500D N150
Expanding an existing PLC network by adding a new PL500D N150
Take note of the PL500D N150 WiFi key before the networking procedure.
You will find the unique adapter key on the label on the back of the housing.
Plug the PL500D N150 into a wall socket. As soon as the indicator light
of the PLC button lights green (afterapprox. 45 seconds), the adapter is
ready to operate.
If you only want to use the Wi-Fi function on the PL500D N150, plug the
adapter into a power outlet, without any cables whatsoever. You can also
connect the PL500D N150 to the network jack of a network device, such as
a computer, with a commercially available network cable. (see 'Example
applications')
Note: The power outlet should be in range of the connected network device.
The PL500D N150 with the cable-based network device should be easy to
access.
To switch off the PL500D N150 or disconnect it from the mains supply, pull
the power plug out of the power outlet.
Ifyouhave already securedyourexisting PLC networkusingthe encryp-
tionbutton,usethesamemethodtointegratefurtheradapters.Onceyou
have successfully connected the new PL500D N150, first press the

In this area you can control the access to the configuration interface as well
as enable and disable the functions of the interfaces and buttons on the
PL500D N150.
Password
You can set a login password for access to the configuration interface.
Bydefault, thebuilt-in configurationinterfaceof thePL500D N150 is notpro-
tected with a password. However, we recommend assigning a password
when the installation of the PL500D N150 is complete to protect it against
tampering by third parties.
To do so, first enter (if present) the current password and then enter the
desirednewpasswordtwice.Nowtheconfigurationinterfaceisprotected

Call up the configuration interface again later.
Enter admin in the User name field and your individual password in the
Password field.
The admin user name cannot be changed.
4.4.2 Network settings
The PL500D N150 also communicates via the TCP/IP protocol as a compo-
nent of your home network. The IP address required for this can either be
entered manually or obtained automatically from a DHCP server.
The option Use this to accept network settings automatically from a
DHCP server is enabled in the factory defaults.
If a DHCP server is already present in the network for giving out IP
addresses,havethe option Use this to accept network settings automati-
cally from a DHCP server enabled so that the PL500D N150 automatically
receives an address from it.
You can also assign a static IP address by making entries under IP address
(e.g. '192.168.0.249') and Netmask (e.g. 255.255.255.0).
If you happen to forget the IP address of your PL500D N150, proceed as
described under 'Calling up the built-in configuration interface'.
