    11-1. Online resources The Nautel website provides useful resources to keep you up to date on your Exporter Plus. Nautel User Group (NUG) The website includes a special section that customers can log into in order to access the Nautel customer newsletter, product manuals, frequently asked questions (FAQ), information sheets, and information about field upgrades.
  • Page 12 Exporter Plus Technical Instruction Manual Online documentation The website’s NUG section provides online access to all the documentation for your Exporter Plus. Documentation is provided in Acrobat (PDF) format. You can use the documentation online or print the sections that you need.
  • Page 13 Exporter Plus accepts AES/EBU -format audio from an audio processor. In FM systems, the Exporter Plus will also accept program service data ( PSD ) for the main program service ( MPS) audio and Advanced Application Service data from an Importer via the Ethernet port. The MPS audio is coded and merged with PSD and Importer data to create a single data stream that is delivered to the FM exciter, also over the Ethernet port.

    150 kbs is recommended. For AM systems, it is possible to use the Exporter Plus at the studio, however this may be impractical due to AM’s need for higher IBOC data rates (because IBOC data includes analog audio) and because any network packet loss will affect both analog and IBOC transmission.

    IP = 192.168.1.4 IP = 192.168.1.5 In this case, only one Ethernet port ( ETH0 ) on the Exporter Plus requires configuration and IP forwarding is not required. If access to devices on other subnets is not necessary, then gateway address configuration is also not required.
  • Page 17 Description Multiple subnets The Exporter Plus has dual Ethernet ports that can be used to isolate IBOC data from other network IP traffic. The potential problem is that IBOC data is a streaming format with embedded timing information which can be degraded if flowing through a busy local area network.

    Allow at least 1U (1.75 inches) of clearance above the Exporter Plus for adequate ventilation. CAUTION: Do not block the vents in the top cover or on the side of the Exporter Plus. This is especially important in higher ambient temperature environments. Weights The Exporter Plus weighs approximately 15 lbs (6.8 kg).

    30.4°C (87°F). Cooler temperatures are recommended, in order to improve the reli- ability of the Exporter Plus. • If the Exporter Plus is used in high ambient temperature conditions, make sure that all of its ventilation holes are completely free of blockage.

  • Page 23: Pre-Installation Tasks

    Preparing for installation To prepare for installation of an Exporter Plus, perform the following tasks: 1. Select a location for the Exporter Plus in the studio or the transmitter site. For detailed information, see “Selecting a location for the Exporter Plus” on page 2-2.

  • Page 24: Selecting A Location For The Exporter Plus

    2. In addition, it is normal to insert MPS audio processing on both of the MPS audio paths to the Exporter Plus. Since one path is for the IBOC MPS and the other is for analog MPS , audio processing requirements are different, requiring two audio processors (Figure 2.1).

    To install an Exporter Plus, perform the following tasks: 1. Unpack the Exporter Plus from its shipping box. 2. Remove the Exporter Plus’s top cover, then remove any packing material, particularly above the CPU. Make sure that there are no loose components, and that all connectors and PCI cards are properly seated.

  • Page 40 Prior to starting this procedure, ensure that the IBOC carriers cannot be broadcast, either by muting the exciter, or by disconnecting the LAN connection from the Exporter Plus. 1. Turn on an audio processor (or audio processors) and verify that the audio is OK 2.
  • Page 41 Exporter Plus Technical Instruction Manual Quick setup procedure Verifying operating mode The operating mode of the Exporter Plus is typically set at the factory. Verify the operating mode is set properly as follows: Figure 6.2: Verifying Operating Mode 1. From the UI’s Edit Settings - System Settings page, select Operating Mode (see Figure 6.2).

  • Page 42: Setting Time Zone Offset

    Quick setup procedure Setting time zone offset Set the time zone offset as follows: Note: Exporter Plus time is derived via the GPS system. If satellites are being received, time will be set accordingly. Figure 6.3: Setting Time Zone Offset 1.

    Figure 1.6 on page 1-5). IBOC data is sent from the Exporter Plus (via ETH 0) to the exciter, over a dedicated subnet, using a standard Ethernet connection. Also, supplying MPS program service data (title, artist, etc.) requires an Ethernet connection to the MPS automation system, on the primary subnet.
  • Page 44 Eth 0 is typically used to connect to the Exgine or Importer. Eth 1 can optionally be used to connect tthe Exporter Plus to a customer network. To access external networks, set the Default Gateway IP for the IP of the customer supplied router.

  • Page 45: Configuring The Exciter

    Quick setup procedure Configuring the exciter The Exporter Plus must be able to connect to an exciter. To perform this task, you must obtain the IP address and exciter link port number for the exciter. If the IP connection between the Exporter Plus and the exciter is unidirectional, then you will also need the MAC address of the exciter.

From the UI’s View Status page, select either Analog Levels or Digital Levels (see Figure 6.7).

  • Page 48: Checking Gps Status

    1. From the UI’s View Status page, select GPS Status (see Figure 6.8). 2. Check that the Status line displays TIME SYNC , which indicates the Exporter Plus is locked to the GPS system. It may take up to 15 minutes after power up to reach this state.

  • Page 49: Checking Lan Status

    2. Verify the IP address and netmask address are correct. If UP is displayed, your network is connected. Use a PC connected to the network to ‘ping’ the Exporter Plus IP addresses. 3. Refer to Section 10, “Troubleshooting” on page 10-1 if there is a problem.

  • Page 50: Setting Audio Diversity Delay

    Diversity delay is normally only required for FM systems. For AM systems, the factory configured delay should not require adjustment. The diversity delay should be calibrated during the Exporter Plus/exciter installation. Thereafter, it may require adjustment after changes are made to any devices in the digital data path, or to audio processing.
