Section 1: Description
This section provides a description of the Importer Plus and its associated digital radio system.
•Overview
•Physical requirements - see page 1-4
•Cooling requirements - see page 1-5
Overview
The Importer Plus is used in digital radio transmission systems with Nautel's NE IBOC
(In-Band-On-Channel) signal generator (see Figure 1.2 on page 1-2) , Exporter (see Figure 1.3 on
page 1-2) or Exporter Plus (see Figure 1.4 on page 1-3) . The Importer Plus allows multiple
broadcasts within a single FM channel. It consists of a PC with compatible audio cards to support the
secondary program. The Importer Plus' application software enables partitioning of the available
transmitted HD (high definition) data bandwidth, between main program service (MPS) audio and
other audio and data services, collectively called advanced application services (AAS). Audio AAS are
called secondary program services (SPS), and include and program associated data (PAD).
The front panel has a hinged cover, behind which are LEDs to indicate hard drive activity (HDD)
and power, two USB ports and a power switch (see Figure 1.1). The rear panel has standard PC
connections for monitor, mouse, keyboard and a USB port. Installed audio card(s) include cables and
connectors for audio, and synchronizing inputs and outputs (specific to the type of audio card).

Cooling requirements
This section provides information about heating and cooling requirements for the Importer Plus.
• Do not allow the Importer Plus room ambient air temperature to exceed 30°C (86°F)at sea
level. De-rate 3ºC (5.4°F) per 500 m – or 2ºC (3.6°F) per 1,000 feet – above sea level.
Example:
At 1,600 m (1 mile) above sea level, maximum ambient temperature should not exceed
20.4°C (67°F). Cooler temperatures are recommended, in order to improve the reliability of
the Importer.
• Do not install the Importer Plus next to other warm equipment.

Issue 0.02 2010-03-29 Page 2-1
Section 2: Pre-installation tasks
This section provides a list of tasks that you must perform prior to delivery and installation of the
Importer Plus.
Preparing for installation
To prepare for installation of an Importer Plus, perform the following tasks:
1. Ensure the correct Importer configuration is ordered. Consider the audio card, SPS (analog
or AES), and equipment requirements. For detailed information, see “Configuring the
Importer Plus audio” on page 2-2.
2. Select a location for the Importer Plus in the studio or the transmitter site. For detailed
information, see “Selecting a location for the Importer Plus” on page 2-2.
3. Prepare the network (LAN) connection between the Importer Plus and the NE IBOC,
Exporter or Exporter Plus. Consider the Importer Plus's location and the amount of other
networked equipment at the transmitter site. For detailed information, see “Planning the
LAN connection” on page 2-3.
4. Consult your network manager to obtain IP address information for the Importer Plus, NE
IBOC, Exporter or Exporter Plus, and gateway. For detailed information, see “IP address
information” on page 2-5.
5. If you are going to use SPS sample rate synchronization, determine how it can best be
implemented.
For detailed information, see “Synchronizing the SPS sample rate” on page 2-6.
6. Order any accessories or optional equipment that you may need. See “Parts and tools” on
page 7-1.
7. Train your station technicians and operators on the use of the Importer Plus. For a list of
available technical and user documents, see the About this manual section at the beginning of
this document. For information about Nautel training courses, go to the Nautel website at
http://www.nautel.com/support/training/

YOUR MANUFACTURER’S WARRANTY. FOR MORE INFORMATION, REVIEW
YOUR WARRANTY DOCUMENTS.

Configuring the Importer Plus audio
1. Importer Plus audio card configurations may differ depending on the options specified, but
in general, there will be two audio channels.
2. You must use AES format audio and the sample rate must be set to 44.1 kHz.
3. For best audio performance, synchronize the 44.1 kHz audio sample rate to the HD system
10 MHz reference. See also “Synchronizing the SPS sample rate” on page 2-6.
Selecting a location for the Importer Plus
To ensure that the desired location for the Importer Plus is suitable, perform the following tasks.
1. Determine whether the Importer Plus and its host cabinet will be located in the studio or the
transmitter site. Consider the following choices and associated requirements:
a) If you install the Importer Plus at the transmitter site with the associated NE IBOC,
Exporter or Exporter Plus, you will ease the connection required between the studio and the
transmitter site. In this case you will need to send only SPS audio to the Importer Plus rather
than a LAN connection. See also “Planning the LAN connection” on page 2-3.
b) If you install the Importer Plus at the studio, regardless of the location of the NE IBOC,
Exporter or Exporter Plus, you will need to provide a LAN connection over the studio-
transmitter link (STL). Ensure the STL can support this capability. See also “Planning the
LAN connection” on page 2-3.
2. Ensure you have a cabinet and room space suitable for installing the Importer. See “Physical
requirements” on page 1-4 and “Cooling requirements” on page 1-5.
3. Ensure the Importer Plus is near a standard ac power outlet, 100 - 240 V ac.
