HDX Network Settings
The HDX differs slightly 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 playback and has one IP address. The Front Display
Controller runs the front panel user interface and has a different IP address. The Main
Controller and Front Display 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 Display Controller are connected inside the HDX:
The HDX is always 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 always be used unless it has been
determined that a static address is absolutely essential for a given installation.
In DHCP mode the HDX Main Controller and Front Panel Controller both acquire an IP address
automatically when the HDX first starts.
