INSTALLATION PLANNING OVERVIEW
The proper cable installation, placement of filter/amplifier, frequency planning and
home preparation for signal coexistence should be planned out thoroughly before
deploying the DXN-W224
Inadequate planning will not only affect the DXN-W224 network but also cause
unwanted interference with other existing services. The following section discusses
these installation considerations in more detail.
Proper Cable Installation
The rooms qualified to be part of the DXN-W224 network should have an existing
coaxial connection and the following characteristics:
• The room is capable of receiving good quality analog television service
(no set-top box required) over the coaxial cable.
• The room is capable of receiving digital television services using a
set-top box.
If the room cannot receive digital or good quality analog television services, the
Ethernet-Coaxial network capabilities may be compromised to this location.
Amplifier Bypassing
An electronic amplifier is a device that boosts a weak signal. The typical amplifier
cannot pass DXN-W224 network signal because they are designed to be
unidirectional devices. Hence, the amplifier should be uninstalled or bypassed if
possible. To bypass an amplifier, user will need to install Diplexers to separate the
DXN-W224 signal and other signal first and only install the amplifier between the
paths of none DXN-W224 network signal.
Frequency Planning
The DXN-W224 is capable of operating between frequency bands of 1125MHz and
1525MHz. In order to avoid interference between the DXN-W224 device and other
devices on the same cable network, DXN-W224 device must operate at a frequency
spectrum that is different from other devices.
•5-42MHz (Internet Access Upstream)
• 42-850MHz (Internet Access downstream)
• 50-806MHz (Off-Air TV)
• 50-860MHz (Cable TV)
• 950-2150MHz (Satellite L-Band)

One common scenario is where DXN-W224, cable television and high-speed Internet
service need to coexist. The cable television in United States operates between
50-860MHz while high-speed Internet service upstream and downstream operate
between 5-42MHz and 42-850 MHz respectively. Hence, the logical choice for
DXN-W224 frequency would be between 940-1500MHz. The similar frequencies
planning approach should be taken into consideration when dealing with Satellite
and off-air antenna.
Terrestrial Television (Off-Air)
If you are receiving terrestrial television service using a broadband antenna, then
additional components may have to be installed in order to be compliant with
governmental regulations. DXN-W224 network signals operating in the 1125 to 1525
MHz range should be prevented from radiating out of the antenna by using a small,
in-line Low Pass Filter(LPF-860Mhz). This filter will prevent DXN-W224 network
signals from reaching the antenna.
Cable Television (CATV)
For a cable television subscriber, there are no additional components required to
work with the DXN-W224 on the same cable network. The user may choose to install
the DXN-W224 on the network and use it as-is if data rate is acceptable. Else, user
may improve DXN-W224 network performance by inserting a Low Pass Filter
(LPF-860Mhz) at Point of Entry (POE) where the drop cable enters the house.
DBS Satellite Television with Terrestrial Television (Off-Air)
The Direct Broadcast Satellite (DBS) uses proprietary satellite channel-stacking
switch or Low-Noise Block (LNB) to distribute the resulting signal (usually 950 to
2150 MHz) in the same cable network that carries the lower-frequency terrestrial
television from an outdoor antenna. Another Diplexer then separates the signals to
the receiver of the TV set and the DBS set-top box (STB).
Most of the satellite switches are not designed to pass DXN-W224 network signal
and prevents it from forming a network. It is recommended that satellite signal and
DXN-W224 network signal should remain on separate cable networks. If separate
wiring cannot be done, then additional components have to be installed:
1. Install Triplexer to separate UHF/VHF, DXN-W224, and DBS signals.
2. Install MoCA Coupler switch before the satellite switch.
Existing OSP installed MoCA network
The DXN-W224 will automatically scan for an available channel and form

Ethernet-Coaxial network. This may cause issue with the existing OSP MoCA network.
It will not be permitted to join the OSP MoCA network unless utilizing the same
frequency and password.
The remedy in this situation is to use the DXN-W224 software utility to configure the
DXN-W224 to be on the same frequency with the same privacy network as the
existing OSP MoCA network.

HARDWARE INSTALLATION
Power
Plug the DXN-W224 into an AC wall outlet or power strip.
Note: Power source is confirmed when the green LED Power indicator on the
DXN-W224 is illuminated.
Connect the Ethernet Cable
Connect the included Ethernet cable to the LAN port located on the DXN-W224 and
attached the other end of the Ethernet cable to the network or PC.
Connect the Coaxial Cable
Connect coaxial cable to the Coax I/O port located on DXN-W224 and attached the
other end of the coax cable to your cable jack inside the house.
Note: Please make sure the DXN-W224’s configuration switch is in
MoCA mode. Coaxial Network Connectivity is confirmed when the green LED COAX
indicator on the DXN-W224 is illuminated.
If there is TV service being received in the room and you wish to continue viewing
the service, connect the other coax cable to the TV Out port on the DXN-W224 and
attach the other end of the coax cable to your television, Set-top Box (STB), or VCR
as desired.

SOFTWARE INSTALLATION
D-Link DXN-224 comes with software web-based configuration to allow
control over certain coaxial networking parameter. The unit is shipped
with default parameters that will allow operation on most coaxial
network without any additional configuration.
However, if a special network security password is required or if a
specific channel operating frequencies is required, then the default
parameters will need to be modified.
Web-based Configuration Utility
To access the configuration utility, open a web-browser such as Internet Explorer
and enter the IP address of the router (192.168.0.50).
