HomePNA 1.0 is a standard defined and ratified by the
Home Phoneline Networking Association (HomePNA).
Currently HomePNA 2.0 is scheduled to be ratified in the
fourth quarter of 1999. The DHN-520 was designed around
the proposed iLine10standard, which was accepted by
the HomePNA on July 27, 1999 as the basis for HomePNA
2.0. At the time of this manual’s printing HomePNA 2.0 has
not been officially ratified.
Home Phoneline Networking allows a home user to build a
network utilizing their standard home phonelines. It
removes the need to install separate hardware or specialty
cables as is required by other networking technologies.
With a full 10 megabits per second (Mbps) of bandwidth,

the data throughput speed is effectively 150-200 times
faster than a V.90 modem.
This technology will allow a Microsoft Windows 95 OSR2,
Windows 98 or Windows NT (and the future Windows 2000)
user to quickly share files and printers. Users can play
multi-player network games and share Internet access by
using additional software.

Under ordinary circumstances, your D-Link DHN-520
will not be affected by static charges such as may be
received through your body during handling of the
unit. In special circumstances where you might carry
an extraordinarily high static charge, it is good
practice to reduce the charge by touching a
grounded object before handling the adapter.
Open the shipping carton and carefully remove all items. In
addition to this user's guide, ascertain that you have:
• One DHN-520 home phoneline network adapter.
• One DHN-520 software CD.
• One phoneline cable.
• One D-Link DHN-520 User’s Guide (this manual)

1. Shut down the computer, unplug its power cord, and
remove the cover.
2. Insert the DHN-520’s board-edge contacts into any
available PCI Bus Master expansion slot. Press the
adapter firmly into the slot, making sure the contacts
are firmly seated.
3. Install the bracket screw that secures the card to the
computer chassis.
4. Replace the computer's cover.
5. Reconnect the computer's power cord and turn the
computer on. If your computer’s BIOS is plug-and-play
compliant, it will automatically configure the DHN-520
upon power-up.

Standard phoneline cable can be used to either connect the
adapter to a phoneline wall jack, or to another adapter. It is
important to note that when two adapters are connected
directly, a second cable must be used to connect the
computers to an active phoneline. The adapter requires the
voltage running in an active phoneline to operate properly.

On account of the great variety of network environments for
which the DHN-520 may be used, and revisions of those
network systems, the instructions for software installation
are given as HELP files on the DHN-520 Software CD.
Review the root directory HELP for overview information,
and for full installation details, see the HELP and
referenced instruction files in the sub-directory appropriate
to your network operating system.
Additionally, on the Driver CD we have provided an HTML
manual designed for our DHN-910 10-Mbps Home
Phoneline Network in a Box. It is an HTML rendered copy
of the full Quick Starter Guide that accompanies the
network kit. Simply open the StartHere.htm file in the

If you experience any problems with the adapter, first
verify that the appropriate driver is loaded and that the
cables are properly connected.
1. Ascertain that the adapter is fully and firmly seated in
the slot connector.
2. Check the cables. You might wish to plug a standard
phone into an active phone jack to test both the line and
cable.
3. Ascertain that the adapter's PCI slot is not deactivated
at the BIOS level. The CMOS setup utility in PCI
computers ordinarily provides the option to activate or
deactivate PCI slots. Refer to the motherboard’s user
guide for more information.
4. Replace the adapter in question with a verified adapter
and run NIC (software) diagnostic tests.
5. Install the questioned adapter in another PCI computer
and run the tests again.
6. Remove all other PCI adapters from the computer and
run the tests again. If the verification/diagnostic run is
not normal, then there is probably an interrupt number
conflict, which will have to be resolved manually by

running the CMOS setup utility after you have
reinstalled all of the expansion cards.
The DHN-520 Adapter features two LED indicators to
assist in the resolving of network diagnostics:
• LINK Indicator
A steady green LED indicates good linkage between one
DHN-520 and another.
• ACTIVITY Indicator
A flashing green LED indicates that the adapter is
sending or receiving data.
