To accomplish this, it utilizes a network of up to eight Remote Audio Devices (or RADs) that are connected via CAT 5 cable to a single Mongoose host. A RAD, designed to mount inside a standard US two or four gang switchbox, uses high value, professional quality technology to transmit and receive up to four channels of digital audio –...
System Requirements To include a Mongoose/RAD network in an audio system, the system must meet the following requirements: If you plan to use CobraNet to communicate between a Mongoose and other audio devices, those devices must be CobraNet-enabled. • You must have access to a computer running Microsoft Windows® XP (Service Pack 2 or higher) or any version of Vista or Windows 7 (including 64-bit).
Design Manual SECTION 2: UNDERSTANDING THE MONGOOSE SYSTEM Rane understands the pain and expense of pulling and managing miles of analog cable throughout a large audio installation, not to mention the potential for inferior sound quality. The advent and rapid adoption of digital audio networking has almost ended this cabling and quality nightmare –...
CobraNet network. Each RAD input amplifies, digitizes, and transmits the digital audio via CAT 5 to its host Mongoose, whereupon it can be routed to another RAD, to a CobraNet Bundle, or both. Each output RAD receives via CAT 5 a digital signal and converts it to analog for delivery to the attached device.
Less Expensive Cabling and Conduit The foremost advantage of the Mongoose system is its use of CAT 5 cables for audio distribution. We don’t have to tell you the cost benefits of using CAT 5 versus shielded audio cables and conduit. But bear with us.
A Mongoose system contains three primary components: 1. The host device (called the Mongoose) to which you can connect up to eight RADs. You can then connect the Mongoose to your Ethernet network (for setup and control) and to additional CobraNet-enabled audio equipment.
The Mongoose Host Device The primary purpose of the Mongoose host device is to connect up to eight RADs to a CobraNet network. It is typically housed in the audio rack room along with the DSP and other audio equipment. In addition to hosting the RADs, the Mongoose does the following: • Provides power to the connected RADs...

Link/Activity LED (green) – indicates the CobraNet network is connected, and flashes if there � is activity on the network. If the Mongoose is connected to another CobraNet device or network switch but the Link LED is off, this indicates a problem with the connection. If you have connect- ed both the primary and secondary CobraNet ports, the Link LED for both ports should be on.
Power LED – lights solidly if the Mongoose is supplying adequate power to the RAD port. � 6 Ethernet port – used to connect the Mongoose to an Ethernet switch or directly to a computer. Note that this Ethernet port contains auto-MDIX functionality, which means that if you connect directly from this port to a computer, you can use either a standard Ethernet patch cable or a crossover cable to make the connection.

For the most recent list of RAD models available, see www.rane.com/mongoose. The CAT 5 cable that connects the RAD to the Mongoose also provides power to the RAD as well as a path for data communications. This makes it possible to control the RAD’s configuration settings, view status information, and update a RAD’s firmware –...
8 Audio Tx LED – displays solid green if communication with the Mongoose has been established and the Mongoose informs the RAD of the Tx Audio lock. The light displays solid red, if there is a prob- lem communicating with the RAD or if there is a problem with the Audio Tx pair of wires.
Using the Mongoose Tracker, you configure each Mongoose RAD port with the RAD model that should be connected to it. You also configure various settings for each RAD, for the Mongoose itself, and for the CobraNet network. One of the key configuration tasks is to set up the audio routing for your Mongoose system.
Understanding how the Audio is Routed Understanding how the audio signal finds its way back and forth between a RAD and the host Mongoose is fairly straightforward. It’s literally a direct connection. But where does it go from there and how do you control it? Depending on your audio system, there are several options for routing a RAD audio signal.

1. Does the audio system you’re designing actually need the Mongoose technology? If you read the introduction to this manual (or listened carefully to the Mongoose sales pitch), you understand the benefits of using a Mongoose system. Deciding which situations warrant its use is the trickier part.
If distance is an issue, however, you may want to add additional Mongoose devices that you can place close to the RADs. See the previous question for more details about distance issues.
Bundle numbers associated with the Mongoose host device, and the routing of audio to and from the Mongoose CobraNet Bundles. If you want to view and manage other CobraNet settings not included in the Mongoose Tracker, you can do so using an SNMP MIB browser or the CobraNet Disco software.
They plan to install a projection system that will transmit the audio from the sanctuary to this meeting room. Mongoose technology is perfect for this situation. Since the meeting room is across the street from the church (and the source of the audio signal), installing analog cables could prove problematic. Even with the addition of isolation transformers, there is absolutely no guarantee that the sound quality will be suitable.
Figure 26: Floor plan of Saint Dawkins Church tie-line application Note: In the above situation, you may be tempted to place another Mongoose in the overflow hall and use a wireless network to connect them. Wireless CobraNet communication is currently not supported, however, so this solution is not possible.

In this example, the Mongoose is a wise choice because it provides the school with tremendous flexibility and extensibility. While delivering superb sound quality in the cafetorium, it also ties in with the existing school paging system, and provides the possibility of additional functionality in the future (as new RADs are introduced).

Following is a screen shot of the configuration’s main window, including the routing matrix: Figure 32: Configuration for Cafetorium example application (routing RADs from a single Mongoose to and from a CobraNet device)
The following sample application is a bit more complex. It is a hotel that contains several meeting rooms, a ballroom, and a restaurant/bar. It is a prime target for the Mongoose because of the low channel count in each room and the scattered locations of each audio input and output. This system requires more than eight RADs and, therefore, requires more than one Mongoose.
• Two RAD4s to accommodate two to four powered speakers. Rack Room • Because there are 16 RADs in this system, two Mongoose devices are required. As you can see from the illustration, the eight RADs located in the Meerkat and Cusimance rooms are connected to one Mongoose while the eight RADs located in the Atilax Ballroom and the restaurant/bar are connected to the other Mongoose.

CobraNet Bundle to CobraNet Bundle The final example application illustrates the benefits of the Mongoose’s ability to aggregate audio channels. In this example, we move to the campus of a small college – Kipling College. To help focus, we highlight a small portion of what would likely be a much larger audio system.
Bundles is used for receipt of the music/television channels. This leaves only one Bundle for receipt of the microphone signals from both the student union and the cafeteria. Without the Mongoose, this would be impossible and an additional DSP box would need to be purchased. Using Mongoose technology, however, you can combine the microphone signals from disparate locations into a single CobraNet Bundle, eliminating the need for that additional DSP box.

SECTION 4: INSTALLATION AND CONFIGURATION ISSUES This section discusses general installation issues you may consider prior to handing your design over to the installer. The actual details of installing the product are covered in the Mongoose Installation Guide. Key Installation Tasks and Recommended Work Flow...
1. When installing the equipment on-site, it is best to install the CAT 5 wiring first, then install, connect, and power on the Mongoose, and then install the RADs. Done in this order, you can verify that the RADs are working properly as soon as you connect them. If you also configure the Mongoose prior to installing the RADs, you can verify upon installation of the RAD if its model matches the model configured for this port on the Mongoose.
IP addresses to the devices on the network. The Mongoose system is no exception. After all, the computer has to have some way of finding the Mongoose devices on the network. You’ll be glad to know, however, that the engineers at Rane designed the Mongoose to greatly simplify this process.
You use the CobraNet port to provide a network path for audio data to and from the Mongoose. There are two CobraNet ports on the back of the Mongoose – Primary and Secondary. Use the Primary port for your main CobraNet network. Use the Secondary port only if your system includes a backup CobraNet network.
Mongoose devices to configure, you must connect your computer directly to each device, one at a time. This means you must be in close proximity to each Mongoose you want to view or configure. Another possible disadvantage is the lack of Internet access from the computer.
Control Network If you need to manage multiple devices (multiple Mongoose devices and/or other Ethernet- controlled equipment), you may want to connect all the devices to an isolated network switch. By connecting your computer to the same switch, you can easily and quickly access each of the devices to perform management and configuration tasks.
CobraNet network. If there is an existing CobraNet network, you will likely want to integrate the Mongoose system into it. To do so, just connect the Mongoose devices to the current CobraNet network switch. Advantages to this approach include the ability of the Mongoose system to send or receive audio from any other device in the network and the ability to centrally manage all your CobraNet devices (using SNMP or the Disco utility).
In addition, this approach likely provides Internet access as well. Also, if the existing data network contains a VPN (Virtual Private Network), you can connect to the Mongoose system from a remote location. If you plan to integrate with an existing network, consult the organization’s IT department.
4. Use existing network hardware, but isolate the CobraNet and/or control network As described in the previous section, there are many advantages to integrating the Mongoose control network with an existing network. Since the CobraNet and the control networks use Ethernet and are compatible, it is also possible to integrate the control network and the CobraNet network.

When you apply the file to the Mongoose, its settings are actually saved to the device. The saved configuration file then serves as a backup in case you want to restore the device to a known configuration at a later time.
To access a live device, you open the software’s Device Discovery dialog box. The software automatically discovers and displays all the Mongoose devices it detects on the network. You select the one you want to view. Note the Mongoose device discovery functionality is dynamic. In other words, if a device is added or removed from the system while you are viewing the Device Discovery dialog box, the list of devices changes automatically and immediately.
RADs should match the channel names in the Mongoose Tracker. To help ensure this consistency, the Mongoose Tracker includes a label generation feature that produces a PDF of labels based on the channel names you’ve entered in the software. We highly recommend this feature to create your labels.
Page 59
Note: If you do not need custom labels, you can use the generic labels shipped with the RADs. To generate RAD labels: 1. Within the Mongoose Tracker, open the configuration file from which you want to generate labels. Alternatively, if you have applied the configuration to a device, you can open the device itself.
To determine if you need to update the Mongoose firmware: 1. Open the Device Discovery dialog box by clicking the Discover icon in the toolbar. If a Mongoose in the list contains firmware that is older than (or current and compatible with) the version of Mongoose Tracker running, the button in the Operations column changes to Update Firmware.
• You can request an immediate update check at any time by selecting Check for Updates on the Help menu. • Open the Device Discovery dialog box by clicking the Discover icon in the toolbar. If a Mongoose in the list contains firmware that is newer than the version of Mongoose Tracker you are running, the Device Status column for that Mongoose contains a link that says Requires newer software.
