Introduction to the NP285
Powerline Adapters
One of the major drawbacks in setting up a home network is the absence of the required wiring inside the house to interconnect networked
computers.
In recent years several technologies have attempted to address this issue. The most prominent technology so far is the family of WIFI (802.11
X) products. Recently, however, another technology called Powerline has been introduced. It uses electrical power circuits within the walls of a
building to transmit data from computer to computer. Powerline technology modulates computer data in a way that enables them to use the
power circuit as a medium of transmission from point to point. Using this technology, two computers have a virtual Ethernet connection without
the need to be physically connected to each other.
The NP285 Powerline Adapters are simple to install and use. They have 3 indicator lights (LEDs) and an Ethernet port. The LEDs display the
connection status, as well as other information, enabling detailed diagnosis of system malfunction. The Ethernet port on the NP285 is used to
connect to a network device in the home environment. The NP285 Powerline Adapter has a Australian standard power plug for connection to a
power outlet.
Typical computer networking applications in the home or ofce:
1. Share centrally stored data
2. Share a printer
3. Provide shared access to one Internet connection
4. Connect multiple gaming users over a network.
5. Extend an ADSL or Cable modem connection.
.........and many, many more.
Note: Product warranty does not apply to damage caused by lightning, power surges or wrong voltage usage.

Important Safety Instructions
Please read these instructions carefully:
1. Unplug the NP285 Powerline Adapter from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp
cloth for cleaning.
2. Do not use the NP285 Powerline Adapter near water.
3. The NP285 Powerline Adapter should never be placed near or over a radiator or heat source, or in a built-in installation unless proper
ventilation is provided.
4. The NP285 Powerline Adapter should be only connected to a 240Volt power circuit. If you are not sure of the type of power available,
consult your dealer or local power company.
5. The NP285 Powerline Adapter relies on the building’s electrical installation for short-circuit (over current) protection. Ensure that a fuse or
circuit breaker no larger than 240 VAC is used on the phase conductors (all current-carrying conductors).
6. For maximum performance we advise that you do not use an extension cord or multi power board between the adapter and the AC
power source. Plug the NP285 Powerline Adapter directly into a 240V AC power point if possible.
7. Do not attempt to service the NP285 Powerline Adapter yourself, as opening or removing covers will expose you to dangerous electrical
voltage points and will also void your product warranty.

About Network Security with the NP285
Network Security
Normally the electric meter forms a physical barrier, i.e. only devices connected to this meter can be part of the network and benet from the
phase coupling. We strongly recommend that you use the NP285 Powerline Adapter internal device encryption. Encryption is congured with the
NP285 Powerline Adapter Conguration Utility. Refer to following pages.
How to Use Passwords Correctly
You can improve your security substantially by following some important rules regarding the use of passwords.
•Keep your passwords as secret as possible.
•Never write a password down. Popular, but completely unsuitable storage options include notebooks, wallets and text les in computers.
•Do not pass on your password unnecessarily.
•Select a random password. Use random strings of letters and numbers. Passwords from common language usage are not secure.
•Change the password regularly or immediately if you feel it has been compromised.
•Passwords should be changed as frequently as possible. This requires a little effort, but increases your security considerably. Even if only
the slightest indication of a leak exists, the password should be changed.
Note: Always keep your network secure and use the internal device encryption (the network password) for security. The NP285 can be congured using the NP285 Powerline
Conguration Utility, refer to the following pages.
Network Volume
The maximum number of HomePlug Adapters in a single-family house is theoretically 253 connections, but in practice no more than 10 devices
should be transferring data simultaneously.

Frequently Asked Questions

Powerline Adapters User Guide YML285YML285285
18 www.netcomm.com.au
Frequently Asked Questions
General
What is the Powerline technology?
HomePlug technology uses your electrical grid, already available inside the walls of your house or ofce to transmit data from computer to
computer. HomePlug technology modulates computer data in a way that enables them to use the power grid as a medium of transmission from
point to point. Using this technology, two computers have a virtual Ethernet connection without the need to be physically connected to each other.
Is Powerline technology compatible with other home networking technologies (including phone line, wireless, and structured
wiring)?
Powerline technology does not cause interference to other technologies. In fact, a great deal of work was done to ensure that the products using
Powerline technology would co-exist with other methods of home networking.
Because power outlets are located in nearly every wall of a home, they are a logical choice to use for data connection. Even though some newer
homes are built “network-ready” and pre-wired with Category 5 wiring, they are likely to have rooms or walls without available connectivity.
Powerline technology also eliminates some of the problems with wireless networking, allowing access points to be moved to more convenient
locations in the home thus reducing the need for multiple wireless access points and improving coverage.
Applications
Are the NP285 Powerline Adapter compatible with Linux? Can they be used on any other operating system?
The NP285 Powerline Adapters can be used on all TCP/IP operating systems with an Ethernet port. Drivers are not required for this adapter. But
the supplied Conguration Utility software which assigns the network password operates only with Windows operating systems.
There is no problem with using the Conguration Utility to congure a NP285 Powerline Adapter on a Windows computer and then use the
congured Adapter on a TCP/IP operating system (such as Linux) with an Ethernet port.
Is the NP285 Powerline Adapter compatible with other LAN products?
You can combine the NP285 Powerline Adapter with all other LAN products or with all devices which conform to the IEEE 802.3 standard.
Does the NP285 Powerline Adapter interfere with other domestic appliances?
No, it will not. The NP285 Powerline Adapter is certied according to all essential standards.
Do other domestic appliances interfere with the NP285 Powerline Adapter in their normal operating modes?
All devices that are sold within Australia must have the appropriate certication. For example in Australia all electrical products must be labelled
with the C-Tick emblem to show that they conform to the Australian standard. This ensures that devices do not interfere with each other.
Does the NP285 Powerline Adapter stand for Internet over Power Line?
Yes and No! The NP285 allows you to build a network to make your ADSL or Cable Internet connection available to all power sockets. However,
keep in mind that the Internet connection isn’t provided via the power lines coming into your house but is provided via an ADSL/Cable modem
connected to your ISP service.
Which devices do I need for the initial installation of a NP285 Powerline Adapter network?
You always need a minimum of two adapters for the initial installation. If you want to connect your network to the Internet, you need at least one
adapter to be connected to an ADSL/Cable modem (only one participant of the network can use the Internet) or to an ADSL/Cable modem router
(all participants of the network can use the Internet at the same time).
Can the NP285 Powerline Adapter be operated in other countries in the world or is it restricted to a specied region?
The NP285 Powerline Adapter has a standard power plug for connection to Australian power outlets only.
How many NP285 Powerline Adapters can I operate within a family home?
253 connections are theoretically possible. But in practice, no more than ten (10) devices should be connected and transferring data at the same
time.
If one NP285 Powerline Adapter is connected to a LAN Switch, is it possible that all other computers connected to the Switch can
communicate with all other NP285 Powerline Adapter members?
Yes, this is possible.
Can I create a group of several NP285 Powerline Adapters into a private group and have a common password for that group
only?
Yes, you can. You can use the Conguration Utility to set a common network password within the group or network.

Security
Can my neighbour listen to my data when he is connected to the same power supply?
Your electric meter dampens the signal enormously and represents a natural barrier from your neighbour.
However, if you have power supply lines lying unfavourably close to your neighbour’s power lines, it is possible that your neighbour will benet from
an unintentional phase coupling. We therefore strongly advise you to use the internal device security encryption! By using the Conguration Utility,
enter a network password (that is different from the factory default) and activate the encryption. This will stop eves dropping.
How safe is my data? Is it possible to tap into it in some way?
We strongly advise you to enable the internal device security encryption! This will only allow other NP285 Powerline Adapters to communicate with
each other, providing they have the same password.
Technical
What is the power consumption (in watt) of the NP285 Powerline Adapter from the 240 volt power supply?
The power consumption of the NP285 Powerline Adapter is 3.6 watts, drawn from the power supply system.
On which level does the NP285 Powerline Adapter transmit?
The transmitting power spectrum is -50dBm/Hz, on amateur radio frequencies -80dbm/Hz, with a bandwidth of about 17MHz and that is about
+22dBm (160mW) or about -8dBm (160uW) (all values based on 50 Ohm). As the coupling is symmetrical, only a small part of this performance is
radiated.
Is the NP285 Powerline Adapter compatible with Powerline devices from other manufacturers?
To obtain the optimum performance and usability, we recommend that you only use the NP285 Powerline Adapter. They are tested and have
proven interoperability.
Furthermore, the NP285 Powerline Adapter is also compatible with the HomePlug1.0 standard, i.e. it operates with all other devices being
compatible to this standard.
In my house there are three separate phases. Can the NP285 Powerline Adapter connect one phase to another?
Yes, it can. Phase coupling operates without the installation of a phase coupler using the NP285 Powerline Adapter. You also can establish your
network connections via two or three phases.
I’m living in a very old house with old power supply lines partly without a separated earth wire. Does the NP285 Powerline
Adapter operate in this circumstance?
The NP285 Powerline Adapter will also operate correctly in this case.
Can I plug the NP285 Powerline Adapter into an extension cable or into a multi socket power board or do I have to plug it directly
in the wall socket?
Yes, you can plug the NP285 Powerline Adapter into an extension cable or into a multi socket power board, but remember, the greater the
number of cables and power boards you have the greater the possibility of performance issues.
Do I have to worry about an electric shock from the Ethernet connection?
No, you don’t have to. The two electric circuits are separated from each other.
On which frequencies does the NP285 Powerline Adapter operate? Does this technology interfere with the amateur or normal
Radio reception?
Typically, today’s radio reception (FM) takes place in the range of 87.2 to 108MHz. The frequencies used by the NP285 Powerline Adapter are in
the range of 4MHz to 21MHz so they cannot interfere with your radio reception.
The technology is based on the HomePlug standard in which the transmitting levels are specically lower in the amateur radio band. The
transmitting level is very low and by symmetrical coupling only a small part of this power will be radiated by the power grid.
Is there a risk that electromagnetic interference will be distributed all-over the house, even to the neighbours, when using the
NP285 Powerline Adapters?
The NP285 Powerline Adapter is tested to the same norms as other electric devices (C-Tick and EMR). The NP285 generates the same noise
level as other electrical equipment. The NP285 Powerline Adapter does not produce any more interference than a modern electric power drill.
House hold power circuits operate at 50Hz. Is it possible to achieve reasonable ping times in the range of milliseconds?
The NP285 Powerline Adapter doesn’t operate at the 50Hz alternating frequency. It operates in the Megahertz (MHz) range. Hence the ping times
are in the range of msec.
Is the data carrier rate high enough for a conventional DSL connection?
The bandwidth of the NP285 Powerline Adapter depends on the interferences on your power cabling and of the quality of the electrical installation.
It ranges from 14 MBit to 85 MBit (a conventional DSL connection has 0.512 MBit download and 0.128 MBit upload rates). This is quite sufcient
for extending a DSL connection to all the rooms in your house.

I have the impression, that the carrier rate, which is indicated by the Conguration Utility, are uncommonly low. Which values are
in the realm of normality and what can I do to boost the carrier rate?
Please remember that the carrier rate falls with increasing reach (up to 5000 square feet) and the number of adapters installed. 10 Adapters are
ideal. The maximum throughput that the technology can support is about 85Mbits per second. A more common rate would be ~50Mbits.
To increase the data rate you should ensure that the NP285 Powerline Adapter is directly plugged into the wall socket. Do not use unnecessary
extension cable or multi sockets power boards if you wish to achieve maximum carrier rate.
If this cannot be avoided, please ensure that any multi socket power board do not have any over-voltage or surge protector. This could impair or
even inhibit data transmission. Plug in the least number of devices as well.
In order to increase the distance of my NP285 Powerline Adapter Network, I am looking for a HomePlug Ethernet repeater. Do you
have such a product?
You can increase the distance by combining two NP285 Powerline Adapter networks with two different network passwords. The repeater is built
up by two standard NP285 Powerline Adapters, which you simply connect via an Ethernet RJ45 cable. Please note that physically you are still
using one medium, this means the bandwidth will be shared between both networks. You can repeat this procedure several times.
