War of the Waves
Dear Valued Customer,
It’s with great pride and a tip of the hat to an incredible team that I congratulate you on your new Telos Alliance
product. Everything we do here at the radio division of the Telos Alliance is with one end goal in mind: To help
broadcasters declare victory in extremely competitive environments. By purchasing this product from us, in essence,
you have declared war on your competition.
After all, the majority of Telos Alliance employees were broadcasters themselves once, and the products we’ve
developed over the years have been designed as solutions to specic issues faced on the front lines of our industry.
We’re right there in the trenches with you and have the weapons you need in your arsenal.
Telos Systems is a catalyst to out-of-this-world sound, with the most powerful and popular broadcast telephone
systems in the industry; IP/ISDN codecs and transceivers; plus processing/encoding for streaming audio. We built an
industry on the back of these amazing telephony systems, and they are still going strong.
While we at the Telos Alliance never forget our roots, we are also blazing trails in terms of new technologies like
stream-encoding and AoIP, so that all types of broadcasters can excel in this ever-evolving digital world.
Omnia Audio not only lets you stand out on the dial with your unique signature sound via legendary audio
processors, audio codecs, and microphone processing, it lets you give your listeners a better streaming experience
across devices with innovative stream encoding/processing software and hardware.
Axia Audio is a driving force behind the AES67 AoIP standard, and its networked AoIP radio consoles, audio
interfaces, networked intercom, and software products continue to move AoIP adoption forward and help
broadcasters streamline operations with cohesive, smart, and feature-rich AoIP ecosystems.
Last, but certainly not least, 25-Seven has traditionally been known for its audio delays, but its Voltair watermark
monitor/processor has made a name for itself more recently as the disruptive product that helped broadcasters take
back their ratings and harness the true power of their listening audiences.
You work so hard on your programming day-in and day-out, it deserves technology that will optimize sound and
performance at every point in the airchain and online. Armed with Telos products, you have what you need to set
your competition squarely in your crosshairs.
With that, I’ll leave you to prep your armaments. I hope that you will enjoy your Telos Alliance products for many
years to come!

Chapter 8 covers pin outs of the mixed xNode.
HTML Interface
xNodes provide basic conguration from the front panel interface. Further setup or maintenance is available through
an HTML interface (otherwise known as a web interface). Accessing this interface requires a PC that is on the same
network as the xNode and has an IP address within the same subnet. Using a web browser, the IP address of the
xNode is typed into the URL request eld. Upon accessing the device, an authentication process is required.
The default username and password are:
Username: user
Password: (none)
What is meant by subnet?
In this text, the term subnet is used to designate the network portion of an IP address. An IP address,
192.168.1.15, has a network prex and a host number. Where one ends and the other begins is dened by
the subnet mask. A common class C network will have a “netmask” of 255.255.255.0. Compining these two
values, 192.168.1.15 255.255.255.0 denes the network prex (subnet) as 192.168.1 and denes the host
number as 15. So two devices within the same subnet would have the same prex, but required to have
different host numbers. 192.168.1.15 and 192.168.1.25 for example.

Introducing the xNode • 5
© 2016 Axia Audio - Rev 2.0
The home page will show system information.
Node ID: (shown if ID assigned): An xNode can be assigned an ID which is used to assist with IP addressing and
channel numbering.
Software Version: The code version which is used by the xNode.
Temperature: The temperature reading of the internal censor. Alarm status will appear if the temperature is above
acceptable limits.
Sync (in audio xNodes): Indication if the device is receiving sync from the network. A solid SYNC indication
represents synchronization with the network.
Net1 and 2: Status of the network ports and which is the active port.
Ofine Power and Power Over Ethernet: Status of power sources.
System Uptime: The amount of time since the last bootup.
From the Home page are links to other options. These links are covered in Chapter 3-8.
Using iProbe will allow a user to see all devices on the network. A left click on a device icon will enable the
user to open the conguration user interface (UI). This UI is presented on the screen of iProbe and is the
HTML interface as mentioned here. Authentication is the same through iProbe as with a web browser.

Chapter Two:
Configuration
There are different options for how the xNode can be congured; iProbe, assigning an ID to the xNode, or manually
conguring the IP address. In the fast setup, we will use the ID method. Following subsections of this chapter will
cover the other methods in detail.
Fast Setup
• Apply power to the xNode and wait for the boot process to complete showing you a home screen identify-
ing the xNode and version.
• Press the top button, the screen button, twice to reach the ID page which shows you a Node ID with no
value, Channel numbers 1-8 and no IP address (shown in Figure 2-1)
• Press the second button, pencil icon, for 10 seconds to enter into edit mode.
Figure 2-1
• With the cursor shown, you can use the top button (I+) to increment value and the bottom button ( ) to
move the cursor to the next position. Press “next” button twice and press the increment button once to give
the ID value of 1 to the xNode. (You’ll give a different ID number to each xNode you install.)
• Pressing the move button one additional time completes edit mode and automatically congures the xNode
with IP address 10.216.0.101 and channel numbers of 101 – 108.
• That’s actually the end of fast setup! With IP and channel numbers congured, you can attach the xNode to
your network and begin connecting sources. But let’s continue on for some quick customization.
• Connect a cross over cable between a computer and the xNode or connect the xNode to the appropriately
congured switch.
• Set a static IP address to your computer that has a link to the xNode directly or through a network switch.
(an IP address of 10.216.0.100 would be suitable)
• Open a browser and type in the IP address of the xNode (10.216.0.101) into the URL eld.
• Default Authentication is:
Username: user
Password: (there is no password)

2: Conguration • 7
© 2016 Axia Audio - Rev 2.0
• Select the Simple Setup button to enter into a simple conguration screen for the xNode. The options avail-
able will vary based on the xNode.
• Enter descriptive text in the Source Name elds which describe what devices are connected to the xNode (e.g.
CD player, Turntable, PC Out-1, Aux Input)
• Enter descriptive text into the Name eld under the Destination section which documents what is connected
to the xNode’s outputs (e.g. Control Room Monitors, Headphone, CF Recorder, STL input)
Figure 2-2
• The next step would be to dene the audio that is present at the output. This is done by choosing the browse
button next the channel text box. A popup will appear with a list of sources that are present on the network.
A sample of three xNodes freshly installed into a network is shown in gure 2-2. At this point, not many
sources have been congured with valuable descriptive names. Hopefully you see the value of the good
practice in using the naming elds. Once you have congured all your xNode sources and other Livewire
devices, this browse popup will have more descriptive information which will help you locate the correct
source to assign to an output (Destination).
If you notice in gure 2-2, the three xNodes are showing a default host name which provides little assistance to
the end user. To resolve this you can select the System link under the Advanced Options to change the host name to
something more descriptive (e.g. Studio1-MICs, TOC-AES1, SATRCK-GPIO1).With a descriptive host name ap-
plied to the xNode, a listing of available audio streams will be displayed in a more descriptive manner, i.e., Host-
Mic@Studio1-MICs Guest1@Studio1-MICs CD1@Ctrl1-AES WXYZ-tune@TOC-ANA1, etc.
You’re done! These steps were designed to get you up and running quickly, but if you need more details on other
conguration options, please continue to read this chapter.
For additional information on a particular xNode, look at the following chapters which are dedicated to each
model.

2: Conguration • 8
© 2016 Axia Audio - Rev 2.0
Assigning an IP address manually
If the IP value assigned in the previous steps do not t within your Livewire network plan or you wish to congure
by manual process, you can assign an IP address from the front panel by pressing the page button (top button) until
the IP page is shown.
Press and hold the edit button (bottom button) for 10 seconds.
Figure 2-3
A cursor will appear in the Address eld. Use the top button to increment and the bottom button to move the cursor
to the next position. After 30 seconds of no activity the Edit view will cancel back to the status view. Edit the IP ad-
dress to your needs. Press the next button (bottom) to move the cursor to the next line which is the Netmask setting.
Use the top button to increment the mask to your needs. Press the next button to move to the next line. The NET is
highlighted. Pressing the top button will toggle between the two ports allowing you to select which port is active.
Press the next button (bottom) one more time to complete the edit process. If the cursor returns to the address eld,
then an incorrect value has been entered.
NOTE: You can change the node ID but maintain the same IP address by pressing the increment button
when the IP address is highlighted in the Node ID page. This will toggle between a custom address or the
new address created though the auto conguration process.
Once the xNode has the desired IP value, you can log into the HTML interface with a PC that has a static IP value
within the same subnet as the xNode and connected to the same network. Later in this chapter the Simple Setup
HTML interface is covered. Each following chapter is dedicated to a specic xNode and covers in detail the HTML
pages. .
Assigning an ID
The method of setting an xNode with an ID was covered in the Fast Setup. Some details of this option were left out.
To review the ID method: After the xNode has booted, the title page should show on the OLED display, showing the
name of the node and the software version running. The top button acts as the page toggle function. Press the top
button until the Node ID page is shown. Press and hold the lower button (represented by the pencil icon) for 10 sec-
onds A cursor appears following the word Node. Use the top button to increment the cursor value and use the lower
button to move to the next position. After 30 seconds of no activity, the edit page will reset back to the status page.
Select a unique ID for the xNode. Press the lower button one last time to nalize the edit and return to the status
view. The node has now been given an IP address and the inputs have been given unique channel numbers.
MORE ON ID VALUES: Number ranges of 1-99 (nn) support small-to-medium networks with up to 99 nodes.
The node ID determines the IP address (10.216.0.1nn) and the source channel numbers (nn01-nn08).
Number ranges of 100-319 (abc) support large networks with up to 2299 nodes. When the 3 digit ID is being
used, a second level identier becomes available with range of d=<0-9>. The node ID determines IP address
in range: 10.216.ab.1cd. Channel numbers: abcd1-abcd8.

Once the xNode has been assigned an ID value, the device has an IP address that can be used to access its HTML
conguration interface. Each input has been assigned a unique Livewire channel number. The next conguration
steps are to enter in descriptive names to the inputs and outputs and to assign Livewire sources to the destinations.
The Simple Setup page is covered later in the chapter and details of each xNode are available in following chapters.

iProbe conguration
When an xNode boots and it has no conguration, it will broadcast a bootp request within 4 seconds. The broad-
casts will continue with an increasing delay between messages and randomization until a conguration is set. iProbe
includes a bootp function which will observe the request and provide an option to respond or ignore.
A counter at the bootstrap conguration button will appear when a bootp request is received by iProbe (version 1.2).
Clicking on the button will open the Device Bootstrap and Conguration window.
From the window view, select the device that has issued a bootp request. The conguration options will appear al-
lowing you to push a New IP address, New subnet mask, and a Conguration. If you have no backup conguration
to send, then apply an IP address and proceed to log into the device through the iProbe interface, and congure it per
the “web interface conguration”.
Web interface conguration (“Simple setup”)
Initially accessing the user interface of the xNode will require authentication. The default authentication is:
Username: user
Password: (none)
The initial page is the Home page. Select the “Simple setup” button.
The setup page will vary based on what xNode you are conguring. If it is an audio xNode, there will be a section
for Sources and a section for Destinations. If GPIO (General Purpose Input/Output) functionality is on the xNode,
there will be section for GPIO.

In the Sources section you will provide a name value to help identify the audio source in network advertisements.
If a unique ID was assigned to the node, the sources were automatically given channel numbers. Sources are the
xNode’s audio inputs. These inputs are known within the network as sources and go to Destinations.
Destinations of the xNode are the audio outputs. The Name eld is used for documenting what is connected to the
audio output port. Channel eld is where you select an audio stream from the network to provide audio for the out-
put. If you don’t know the channel number, use the browse button immediately to the right to search the network for
the desired source. Selecting the source from the pop-up window will populate the channel value of the Destination
eld.
The GPIO section provides a name eld for documenting the purpose of the port. The channel eld is used to either
enter in another node’s IP and port for GPIO routing, or a Livewire channel for Control surface logic. More on this
topic is covered in Chapter 7.
Restoring Defaults
Performing factory reset will clear all congurations and return the xNode to a “blank canvas”. To restore default,
execute the following steps.
• Disconnect all power from the xNode, then press and hold the two front panel buttons.
• Apply power to the xNode while continuing to press the buttons.
• xNode will show a countdown timer for factory reset. When the timer reaches 0, release the two buttons.

Chapter Three:
The xNode in depth
This chapter covers details of the xNode family that are shared in common. The xNode is a 1U half-rack device that
can be mounted to a at surface or in an equipment rack with optional accessories.
All xNodes have a common user interface with settings for advanced conguration and maintenance..
Mounting
Optional Surface Mount kit
The optional surface mount kit (p/n 2011-00077) consists of two brackets that are used to secure the xNode to a
wall, under a desk, or almost any at surface.
The brackets secure to the side of the xNode, towards the front panel. There are four holes which are used for secur-
ing metal work to the xNode.
