Networking Basics
All devices that connect to a network have an Internet Protocol (IP) address. This address is
used as a unique identifier on the network and allows communication between devices to
be routed correctl . IP is the standard used b all network devices.
A t pical home network will use a Modem/Router to connect to the Internet and will have a
number of devices connected directl to the Modem/Router. The Modem/Router acts as a
switch to allow intercommunication between the devices on the home network (LAN) and
allows each of the devices to access the Internet (WAN). The Modem/Router also offers
significant protection to the devices on the LAN side as the cannot be contacted directl b
a computer on the WAN side without the LAN side device initiating the communication. The
HDX should never e connected directly to the Internet without a Router in place.
It is usuall the Modem/Router that allocates IP addresses to the different devices on the
home network. The process of d namicall allocating addresses to devices is known as DHCP
and the part of the Modem/Router responsible for this is the DHCP Server. This s stem allows
devices to be connected and disconnected without the user having to make an
adjustments to the device configurations. Because this s stem is the most common and
convenient for home use the HDX ships with DHCP mode ena led. Below is a diagram of a

HDX Network Settings
The HDX differs slightl from most other network devices as it has one network socket but two
IP addresses. Inside the HDX are two separate network devices. The Main Controller is
responsible for ripping CDs and audio pla back and has one IP address. The Front Displa
Controller runs the front panel user interface and has a different IP address. The Main
Controller and Front Displa Controller communicate with each other inside the HDX on a
small internal network, which is exposed on a single network socket. The diagram below
shows how the Main Controller and Front Displa Controller are connected inside the HDX:
The HDX is alwa s shipped from Naim Audio in DHCP mode, as this is the most common and
preferred addressing mode. It is possible to change from DHCP to Static mode using the Naim
Set IP Tool included on a CD ROM that ships with the HDX, although before doing so the
requirements of static IP addressing should be understood.
DHCP addressing mode
This is the preferred addressing mode and should alwa s be used unless it has been
determined that a static address is absolutel essential for a given installation.
In DHCP mode the HDX Main Controller and Front Panel Controller both acquire an IP address
automaticall when the HDX first starts.

Static addressing mode
Static addressing mode should onl be used in the following situations:
• The HDX is being used in a NaimNet or NetStreams setup.
• The HDX is being used with a ‘hardware VPN’ where the network administrator
allocates static IP addresses to each device.
• The HDX is being controlled via Ethernet b a Crestron or AMX control s stem.
• Port forwarding is used to control the HDX from outside the LAN.
• The HDX is to be controlled b a web browser and the network does not have a local
DNS server.
Some of the above scenarios are quite specialist. Unless it is has been determined that the
setup conforms to one of the above, DHCP addressing mode should alwa s be used.
To configure an HDX in static addressing mode the following settings must be known:
• Server IP address – This is the address of the server main controller. This address must
be unique and should not clash with the DHCP server’s address pool (if a DHCP server
is present). E.g. If the Netmask is 255.255.255.0 and the DHCP server allocates
addresses between 192.168.0.2 and 192.168.0.150 then the Server and Front Panel IP
addresses must be set between 192.168.0.151 and 192.168.0.254.
• Front Panel IP address – This is the IP address of the Front Displa Controller. Usual
practice is to allocate the front panel an adjacent address to the server IP address.
E.g. if the server IP address is 192.168.0.10 then the front panel IP address should be set
to 192.168.0.11.
Four ver important rules appl when choosing the addresses for the HDX:
o The Front panel IP address MUST e different from the server IP address
o Both Addresses must e unique (must not e the same as any other IP address
in the network)
o Both addresses must not overlap with the DHCP server address pool.
o Both addresses must e on the same range. i.e. if the server is on 192.168.0.10
and the Netmask is 255.255.255.0 the front panel must be on an address
between 192.168.0.1 and 192.168.0.254 (excluding the server’s own IP
address).
• Net Mask – This determines the range of IP addresses that can communicate with the
HDX. This should be compatible with the other devices on the network. For example
255.255.255.0 is a common Netmask.
• Gateway – This is the IP address that the HDX will use to access the Internet to perform
CD lookups.
• DNS – This is the Domain Naim S stem server that the HDX will use to resolve the IP
address of the Internet providers used for CD track information and album artwork.

Configuring the HDX networking settings
When the correct addressing mode and associated settings have been determined the HDX
can be configured. To do this the Naim Set IP Tool must first be installed on a PC running XP or
Vista. The HDX network settings are then reconfigured using this tool as described below.
After the HDX has been successfull configured it is advisable to make a note of the new
network settings in the back of the user manual for future reference.
Installing the Naim IP Tool Application
The HDX ships with a CD ROM that contains documentation, the Desktop Client application
and the Naim Set IP Tool. Note that the applications on the CD ROM require either Microsoft
Windows XP or Vista to run. The application will not nativel run on an Apple Mac computer
although there wa s of running Windows on a Mac, which are described in the
troubleshooting section. The following steps describe the installation process using Windows
Vista.
1) Insert the Naim CD ROM into the PC drive and locate the folder containing the Naim
Set IP application installer and double click the NaimIPTool.msi installer icon.

2) The Naim Set IP installer will open. Click Next > on the first screen. Then select the
Folder in which to install the application. The default location is shown below and will
be suitable for most t pical installations. Click Next > when read to continue.
3) Press Next > again to confirm then wait while the application installs.

Changing the HDX IP address
1) Select the Naim Set IP Tool from the Start menu.
2) The Set IP Tool will launch and will start the server discover process. This process takes
30 seconds and scans the network for an Naim HDX hard disk pla ers or Naim
Servers.
3) When the discover process has finished the application will show the name and IP
address of an Naim servers found on the Network. In the example below an HDX
called NSHDXD22B has been discovered at IP address 199.199.0.46 and an NS02 at IP
address 199.199.0.253. Select the server that is to have its IP address changed and
click OK.

4) The application shows the current settings for the selected server. If the current
addressing mode is DHCP then Dynamic address (use DHCP) will be selected (see
step 5). If the current addressing mode is Static then Static address will be selected
and the address details will reflect the current network settings (see step 6).
5) To change the addressing mode to Dynamic select the DHCP option then click
Update. The application will now send the new configuration to the server and the
server will reboot (see step 6).

6) To change the addressing mode to Static, select the Static option and enter the
required networking settings. Follow the advice in the previous sections to determine what
these settings should be. Click Update when all the settings have been entered. The
application will now send the new configuration to the HDX and the HDX will reboot.

7) After the network settings have been changed and the Update button clicked (as
described in step 5 or 6) the following screen will be shown. The server will automaticall
shutdown then restart using the new network settings. Check that the message in the Update
Progress window confirms that both the server and front panel configurations were
downloaded successfull . The message displa ed should look like the message below. When
it has been confirmed that the configuration was sent successfull click OK to continue.
8) The following message will then be shown. Click Ok then close the Set IP Tool.

Trou leshooting
The Set IP Tool does not discover the HDX
It is possible that a firewall running on the computer is blocking the communication between
the Set IP Tool and the HDX. If this is suspected to be the case, more detailed information
about how to allow certain applications to communicate through the firewall will be
available from the firewall’s vendor website. This process is usuall known as ‘adding
exceptions to a firewall’.
Incorrect static address settings have een entered y accident
Launch the Set IP Tool, re-enter the details and click update. The new configuration will be
sent to the HDX. Alternativel return the HDX to DHCP mode if the HDX was not intended to
be set to static addressing mode.
The front display permanently shows ‘Please Wait…’
The most likel cause is that the HDX has been configured in static addressing mode with
incompatible settings. Either return the server to DHCP mode or correct the static address
settings. Here are some examples of incompatible settings
1) Example 1
Server IP = 192.168.0.10
Front panel IP = 192.168.0.10
Netmask = 255.255.255.0
In this example the server and front panel IP addresses are identical. Two devices on a
network must never have the same IP address.
2) Example 2
Server IP = 192.168.0.10
Front panel IP = 192.168.1.11
Netmask = 255.255.255.0
In this example the server IP and front panel IP addresses are on different address
ranges. The IP addresses should be changed so the first three parts of the IP are the
same. E.g. 192.168.0.10 and 192.168.0.11
3) Example 3
Server IP = 192.168.0.10
Front panel IP = 10.15.35.50
Netmask = 255.255.255.0
In this example the server and front panel IP addresses are on completel different
ranges. This can happen if an incorrect configuration is sent to the HDX from the
NetStreams Dealer Setup application. Either correct the problem using the Set IP Tool
or check the addressees allocated to the HDX and front panel b the Dealer Setup
application.

CDs do not lookup correctly
This is usuall caused b one of three things:
1) There is no Internet connection.
• Check the HDX is connected to the network
• If Ethernet Over Mains equipment is used, ensure it is plugged in and switched on.
• Check the Internet connection is working on another machine on the same
network. If there appears to be no Internet connection check the network
switches, cabling and Modem/Router (reboot it if necessar ).
2) The Gatewa setting is incorrect
• If the HDX is in static IP mode check the gatewa address is correct.
3) The DNS setting is incorrect
• If the HDX is in DHCP mode check the router is configured using the DNS settings
supplied b the Internet provider.
• If the HDX is in static IP mode check the DNS setting is correct.
After removing then replacing the network ca le, CDs do not lookup and DTC cannot
connect
If the HDX is in DHCP mode and the network connection is removed, the HDX will revert to an
‘auto IP’ address. The auto IP address is unlikel to be compatible with the network to which it
was previousl connected, so, when the HDX is reconnected there will be a period of time
before the HDX can connect to the network. The HDX will eventuall change IP address back
to a compatible address but the time it will take to do this will var depending on network
conditions. The quickest wa to recover from this situation is to ensure the network is
connected and reboot the HDX.
If the network connection to the HDX is regularl lost, for example if the router is routinel
powered off or the network connection to the HDX is onl made when ripping CDs, either:
1) Reboot the HDX ever time the network connection is reconnected
2) Configure the HDX in static IP addressing mode. Ensure the settings are carefull
chosen as described above.
The front display very occasionally shows ‘Please wait…’
This is likel to be caused b the network’s DHCP server giving a new IP address to the HDX.
When the front displa controller receives a new IP address it momentaril shows ‘Please
wait…’ while it saves the new address.
The Set IP tool does not work on Apple Mac computers
The Set IP Tool can onl be run under Microsoft Windows XP or Vista. There are several wa s
that windows programs can be run on a Mac. Two possibilities are:
• Use Boot Camp. This software allows the Mac to run either Windows or the Mac
operating s stem.
• Use Mac Virtualization software like VMWare Fusion or Parallels. This allows Windows to
be run without rebooting the Mac.
These instructions are for HDX. What a out the NS01, NS02 and NS03?
The concepts and procedures described above are identical for the NS01, NS02 and NS03.
The one difference is that the NS01 and NS02 do not have a front displa so onl have one IP
address.

Glossary
• Auto IP Address – The address the HDX will revert to if it is in DHCP mode and there is
no DHCP server.
• DHCP addressing mode – in this mode the DHCP server automaticall allocates the IP
addresses to the HDX.
• DHCP address pool – The address pool is the range of addresses used b the DHCP
server when allocating IP addresses to devices on the network. The current DHCP pool
settings can usuall be determined b checking the Modem/Router configuration.
• DHCP server – This allocates the IP addresses to the devices on the network. In a
t pical home setup the DHCP server is built into the Modem/Router.
• DNS– The Domain Naim S stem is a s stem of converting a domain name (e.g.
www.naimaudio.com) to an IP address. When accessing the Internet the DNS service
is usuall provided b the ISP. The local DNS server in the Mode/Router performs the
same function but on the local network. For example it allows the user to t pe the HDX
name into a web browser (e.g. http://NSHDX1234/) and it translates the HDX name to
the correct IP address.
• Firewall (software) – A software firewall runs on a computer and prevents unwanted
intrusions from other computers. Microsoft Windows XP and Vista are both supplied
with software firewalls. Normall Windows will advise if these are not enabled.
Examples of other software firewall vendors are ZoneAlarm, Norton and Eset. It is
recommended to alwa s run a software firewall on an computer connected to the
Internet.
• Firewall (hardware) – Most Modem/Routers have a build in firewall, often known as a
hardware firewall. These prevent unwanted intrusions from computers on the Internet
b stopping an incoming communication not initiated from the local network. A
hardware firewall is not a substitute for a software firewall and it is recommended that
both are alwa s used together.
• Gateway – This is the IP address that the HDX uses to access the Internet. In a home
network this is often the same IP address as the Modem/Router
• IP Address – This is the unique address of a device on a network. The HDX has two IP
addresses. One for the Main Controller and one for the Front Displa Controller.
• ISP – The Internet Service Provider is the compan that provides the Internet
connection to the home.
• Static addressing mode – in this mode the user manuall allocates the IP addresses to
the HDX. This method is more complicated than DHCP and should onl be used if it
has been determined that static addressing mode is necessar .
• LAN – The Local Area Network is the home network that is ‘behind’ the
Modem/Router.

• Modem/Router – This device has man functions and is usuall the hub of a home
network. It’s functions normall include:
o Broadband modem. Connects the home network to the Internet
o Ethernet switch. Allows multiple devices to be connected together to form a
network
o WiFi access point – Allows wireless connection of devices to the home network
o Firewall – Prevents unwanted intrusions from the Internet
o DHCP server – Automaticall allocates IP addresses
• Netmask – The Netmask determines the range of IP addresses that the HDX can
communicate with. It must be compatible with the other devices on the network. For
example if the Netmask 255.255.255.0 and the IP address is 192.168.0.10 onl devices
in the range 192.168.0.0 to 192.168.0.255 can be accessed.
• WAN – The Wide Area Network is the network ‘outside’ the Modem/Router. This is the
network provided b the ISP and enables connection to the Internet.
