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 specific 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.

Chapter 8 covers pin outs of the mixed xNode.
HTML Interface
xNodes provide basic configuration 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 field. 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 prefix and a host number. Where one ends and the other begins is defined 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 defines the network prefix (subnet) as 192.168.1 and defines the host
number as 15. So two devices within the same subnet would have the same prefix, but required to have
different host numbers. 192.168.1.15 and 192.168.1.25 for example.
© 2016 Axia Audio - Rev 2.0
The home page will show system information.
(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.
Offline 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.
Node ID:
Introducing the xNode • 5
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 configuration 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.
© 2016 Axia Audio - Rev 2.0
Chapter Two:
Configuration
There are different options for how the xNode can be configured; iProbe, assigning an ID to the xNode, or manually
configuring 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 identifying 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 configures the xNode
with IP address 10.216.0.101 and channel numbers of 101 – 108.
2: Configuration • 6
• That’s actually the end of fast setup! With IP and channel numbers configured, 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
configured 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 field.
• Default Authentication is:
Username: user
Password: (there is no password)
© 2016 Axia Audio - Rev 2.0
• Select the Simple Setup button to enter into a simple configuration screen for the xNode. The options available will vary based on the xNode.
• Enter descriptive text in the Source Name fields 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 field 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
2: Configuration • 7
• The next step would be to define 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 figure 2-2. At this point, not many
sources have been configured with valuable descriptive names. Hopefully you see the value of the good
practice in using the naming fields. Once you have configured 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 figure 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 applied to the xNode, a listing of available audio streams will be displayed in a more descriptive manner, i.e., HostMic@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
configuration 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.
© 2016 Axia Audio - Rev 2.0
Assigning an IP address manually
If the IP value assigned in the previous steps do not fit within your Livewire network plan or you wish to configure
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 field. 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 address 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 field,
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 configuration 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 specific xNode and covers in detail the HTML
pages. .
2: Configuration • 8
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 seconds 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 finalize 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 identifier becomes available with range of d=<0-9>. The node ID determines IP address

Once the xNode has been assigned an ID value, the device has an IP address that can be used to access its HTML
configuration interface. Each input has been assigned a unique Livewire channel number. The next configuration
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 configuration
When an xNode boots and it has no configuration, it will broadcast a bootp request within 4 seconds. The broadcasts will continue with an increasing delay between messages and randomization until a configuration 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 configuration button will appear when a bootp request is received by iProbe (version 1.2).

to send, then apply an IP address and proceed to log into the device through the iProbe interface, and configure it per
the “web interface configuration”.
Web interface configuration (“Simple setup”)
2: Configuration • 9
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 configuring. 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.
© 2016 Axia Audio - Rev 2.0
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 field is used for documenting what is connected to the
audio output port. Channel field is where you select an audio stream from the network to provide audio for the output. 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
field.
The GPIO section provides a name field for documenting the purpose of the port. The channel field 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 configurations 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.
2: Configuration • 10
• 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 flat surface or in an equipment rack with optional accessories.
All xNodes have a common user interface with settings for advanced configuration 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 flat surface.
The brackets secure to the side of the xNode, towards the front panel. There are four holes which are used for securing metal work to the xNode.

Username: user
Password: (none)
Home
The home page shows system information and acts as the default page for xNodes.
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 sensor. Alarm status will appear if the temperature is above
acceptable limits.

Status of power sources.
System Uptime: The
amount of time since the last boot up.
The Home page also has a button, “Simple Setup”, which links to the Simple Setup page.
© 2016 Axia Audio - Rev 2.0
Simple Setup
Simple Setup aggregates all of the xNode’s basic config settings on one page, such as ID, source and destination
names, GPIO assignments, phantom power, and asynchronous options. The top portion of the page shows Node ID
settings and would reflect the number applied from the front panel in setup. There are check boxes to permit the
enabling of the software to automatically give the device a host name or Livewire channel numbers based on the ID
value. Auto channel numbering follows these rules:
• Node ID in range nn=<1-99> - Channel numbers: nn01-nn08.
• Node ID in range abc=<100-319>, with second level identifier d=<0-9> - Channel numbers: abcd1-abcd8.
In audio xNodes there are three radio buttons that control the matrix mixer and general device operation. The Stereo
4x4 or Mono 8x8 options disable the matrix mixer functionality (explained later in this chapter) and configure the
device for those modes. The Mix/Custom mode enables the matrix mixer and allows for customization of mono,
stereo, and mixing configurations.
Figure 3-11
Web interface (Advanced options)
Advanced options are mainly used in Audio xNodes. The following are the links that are found under the Advanced
classification.
System
The System page provides network settings, SNMP settings, Syslog settings, authentication password, and firmware
control.
Name of the device on the network. Up to 12 characters using only letters, numbers, or hyphens (no
spaces or special characters). Host name is auto populated when you assign an ID to the xNode providing a unique
name. You may customize this field if you desire.
3: The xNode in depth • 15
Host name:
Network address: The
IP address of the device, as configured either manually or via the Setup button or iProbe
software. The address can be changed here, but once you apply the changes, you will lose connection
and will need to connect to the device with the new IP address you just assigned.
Beginning with software version 1.2, you may configure a management port. By default, NET2 address will be
assigned to 0.0.0.0, which defines the second port as a redundant network port. If you’d rather forsake redundancy
for a separate management port which does not pass Livewire audio, then set an IP address for the NET2 field, then
define which port is the management port and which is the Livewire port.
© 2016 Axia Audio - Rev 2.0
Mask: The
netmask is a filter to which helps to define the subnetwork. This is a topic covered in networking material
widely available. For simplicity, a value of 255.0.0.0 is a wide open filter and a value of 255.255.255.254 is a very
narrow filter. If you are not familiar with how subnetting works, please refer to your network administrator. A value
of 255.255.255.0 is usually suitable for most cases.
Gateway: The
gateway is a device that handles requests and responses from devices that are in different subnets. A
gateway is what is needed when dealing with more than a single subnet. If creating a Livewire network on a dedicated local area network (LAN), then the value of the gateway can likely be ignored. If not familiar with the function
of gateways, please ask your network administrator.
Default setting is for NET1 and NET2 to be Livewire enabled ports. This provides
redundant network ports for audio and control to the same IP address. If you’d rather forsake redundancy to have
a separate management port which is removed from the high bandwidth audio traffic, than apply a value to NET2,
then select which port is to be Livewire enabled, and which is the management port.

Firmware version: The
NOTE Selecting a new version of software to operate under requires a reboot of the xNode. Rebooting will
cause any audio streams to be interrupted until the reboot completes.
If Bank 1 is empty, use the Browse function to locate the desired software that has been downloaded to your computer. Once the file is selected, pressing the Apply button will upload the software into the bank. The process will
not interrupt the operation of the xNode. Once complete, the System page will return and the two banks will show
versions of software.
© 2016 Axia Audio - Rev 2.0
If operating with Bank 1, and you wish to upload a different version, you will select the “commit this version to
Bank 0” and press Apply button. This will move the code to Bank 0 and empty Bank 1.
QOS (Audio xNodes)
Synchronization: Livewire’s clocking system is automatic and largely transparent to end users. If no clock is present on the network, Axia devices negotiate a master by means of priority settings and the lowest MAC address. If a
device comes online into a network that has a clock present, it will not generate clock unless it has priority setting of
7. The xNode does permit variance in determining the source of clock.
Livewire clock priority 3 (the default setting) is suggested for a typical Livewire network. The higher
the priority number given to a node defines the preferred device to become clock master. A value of 7 insists the device becomes master. Livewire STL Snake mode, Master or Slave, are options for applications where a node is at the
remote end of an STL link. (Live streams are not supported while in this mode.) If the application is two dedicated
nodes at either end of a link, one will be selected to Master and the other to Slave. If the remote node is to connect
to a larger network at the studio side, the option to select is Slave—you don’t want the remote node creating clock
for the larger facility. PTP/IEEE 1588 ARB clock class 248 is the option to enable the xNode to participate in the
execution of the best master clock algorithm for a PTP (Precision Time Protocol) network (enabling it to be a master
PTP clock). PTP/IEEE 1588 slave enables the xNode to synchronize to a PTP network. There are various options
in the PTP category to allow the node to be a master of both PTP and the Livewire network or to be a slave to a
PTP grand master but a master to the Livewire network. This permits the xNode to behave as a gateway of sorts for
network synchronization between AES67 devices and legacy Livewire devices. NTP slave is for special applications
that synchronize from an NTP source. (Live streams are not supported under NTP mode.)
Clock mode:
PTP characterizations
(0 – 127) A domain is one or more PTP devices communicating with each other. A domain
association is used to define communication messages. A value of 0 is standard.
PTP domain number:
(E2E or P2P) PTP supports two methods of time correction which alter messaging between devices. All devices within the network should use the same mechanism. The recommended setting is to use
End-to-End (E2E) since more networked devices prefer to support this option.
PTP delay mechanism:
Priority setting from 0-255 is used in the best master clock algorithm (BMC) to
determine a Grandmaster. Lower numbers have higher priority.
3: The xNode in depth • 17
PTP clock priority1/priority2:
PTP clock sync interval: Is the time for sending synchronization messages. A setting of -4 is 16 messages in 1
second. A setting of 1 is 1 message in 2 seconds. The default setting is 0, 1 message per second.
Used to select the desired input to be utilized as an external clock source. This typically would
be used to sync the output ports to a rate different than 48kHz. (Only available on AES/EBU node.)
AES Sync Source:
Defines the clock for the AES/EBU digital audio output ports (AES/EBU xNode and mixed
xNode). The default is to follow the internal 48kHz clock. If an alternate rate is needed, select the other option.
AES Output Sync:
© 2016 Axia Audio - Rev 2.0
Master Node Clock Timebase: The
default is to use the internal 48kHz clock present in the xNode for network
synchronization. If there is good reason to use an external source, you would select the other option. It is suggested
to maintain the default (AES/EBU xNode and mixed xNode).
Mute AES Output: An
option for turning off the digital AES/EBU stream if no network stream is received.
Livewire Advertisement Slot: An
option to define a specific time slot in which the node will send advertisement
information to the network. The default is 0, random. In extremely large facilities, it is possible for several nodes to
randomly become synced in this function. This condition can create jitter issues leading to audio clicks. To resolve
this, each device would need a unique slot value. For most facilities, the 0 value will be suitable.
Live Audio / Clock Streams: These options define the tagging of the packet for Live Audio and clock. Don’t
modify these settings unless instructed to do so by Axia Support.
These options define the tagging of the packet for streams that are not the
Live Audio streams. These should only be adjusted by personnel that understand the options, or by instruction
from Axia support.
AES67 / Standard Audio Streams:
Meters (Audio xNodes)
3: The xNode in depth • 18
The meter page uses a Java script to provide real time meter representation of the audio at the inputs and outputs.
The meter page shows a stereo channel or a mono channel based on the configuration of the xNode and the amount
of channels enabled. The meters are represented in dBFS. Below the meters are gain adjustment buttons which allow
for 1dB adjustment (Large button) and 0.1dB adjustment (Small button).
Figure 3-12
© 2016 Axia Audio - Rev 2.0
Mixer (Audio xNodes)
Introduced in software version 2.0 is the matrix mixer functionality. The most typical configuration of xNode would
be in the Stereo 4x4 mode. In this mode the functionality of the mixer is locked, and the viewer is not able to make
any changes. To unlock the functionality, press the “Enable Custom Mode” button found at the top right. Now the
viewer can left click a cross point and a pop-up appears for setting the cross point at 0dB (unity gain), setting with a
specific gain, or clear the cross point.
Figure 3-13
3: The xNode in depth • 19
The mixer view is organized with inputs into the xNode as rows and outputs from the xNode as columns. Inputs and
outputs are composed of physical connections and network streams. In the case of an AES/EBU input on port 1 of
the AES/EBU xNode turning into the first network stream source of the xNode, the mixer will show the following
view (without the arrows, which are added for clarity).
© 2016 Axia Audio - Rev 2.0
Figure 3-14
Another example with the AES/EBU xNode is all four physical inputs are turned into the first four network stream
sources and a fifth network stream source is the sum of three AES/EBU inputs as shown in figure 3-15.
Figure 3-15
3: The xNode in depth • 20
Notice that the name of the fifth output is changed, and this is accomplished by entering text into the Source Name
field of the Sources page.
The possibilities of what you can achieve with the matrix mixer are quite broad, just keep an eye on the utilization
counter present to the top right of the mixer.
© 2016 Axia Audio - Rev 2.0
Destinations (Audio xNode)
The Destination page typically defines the audio outputs of the xNode. An xNode has four stereo audio output ports,
with the ability to split each stereo channel into two mono outputs. With the introduction of 2.0 software, the Destination page has a new distinction of being more than an xNode outputs view but also a network stream input view.
Historically network stream inputs were always turned into physical outputs. With the matrix mixer function mention previously, these network stream inputs can be turned into network stream outputs. The Destination page is your
view into controlling these network stream inputs. The historical use of network inputs being turned into physical
outputs will still be more common, but it is important to point out this new distinction in order for you to understand
the mixer functionality of 2.0.
Figure 3-16
3: The xNode in depth • 21
The first column is the Name field, used for documenting the physical output or network stream input, which is best
labeled as a destination. For example, SpeakerAMP could document that the destination is to the speaker amplifier.
The Channel column is used to define the network source being called for to this destination. You may type in the
channel number or use the browse button to search the network for the desired source. The Type column defines the
stream type that is being called. Livewire stream types are known as “From Source,” “To Source,” or in some cases
“Surround.” The “To Source” option is a special dynamic return audio known as a backfeed. A backfeed is a channel
automatically generated by Axia consoles for talkback, mix-minus, etc. The Gain column provides adjustment for
the destination from the range of -72dB to +24dB.
© 2016 Axia Audio - Rev 2.0
Sources (Audio xNode)
The Sources page typically defines the physical audio inputs of the xNode. The corresponding network streams are
given a name and a unique channel number that is used to distribute through the network. The xNode provides an
auto-numbering process when you ID the xNode through the node ID process described in Chapter 2.
Source Name column is used to identify the physical input or network stream generated by the xNode (for documentation sake) and is also used in source advertisement through the network.
Channel column is the unique number for each source. This will auto-populate based on the ID given to the xNode.
It is critical that each source in the network has a unique number, not shared with any other source.
Stream Mode column defines how the audio is packetized. Live stereo is the original Livewire stream intended for
microphone or other live audio content that needs a lower delay. A packet contains 12 samples or 250us of audio.
Low Latency Stereo is an option for support of Ravenna and AES67 streams. The packet contains 1ms of audio (48
samples). Standard Stereo is the high efficiency stream that contains 240 sample (5ms of audio), maximizing the
packet size at 1522 bytes. This option is intended for suitable sources, such as playback machines that can use the
higher efficiency with slightly more latency.
Input Gain column provides adjustment of -72dB to +24dB for line level audio and +77dB for microphone audio
inputs. When a source is enabled through the stream mode, an RTSP link will appear under the Source row. This
link can be given to a media player that supports RTSP as well as 24-bit PCM streaming audio for direct auditioning
of the audio stream. VLC 1.1.11, for instance, is a cross-platform media player that supports RTSP. An AES67 SDP
stream description is also provided.
3: The xNode in depth • 22
Unicast Link
Unicast Link page allows configuration of multichannel audio link between locations connected with an Ethernet
network without support for IP multicasting. In particular it can be used as a studio transmitter link. The page functions as a configuration wizard and applying the settings makes changes in audio routing setup and other options
presented on the Sources, Destinations, and QoS pages.
Unicast Link is by default bidirectional. The connection protocol supporting Unicast Link is Real Time Streaming
Protocol (RTSP), which is a TCP/IP protocol. Audio is sent using unicast UDP/IP protocol. A basic setup involves
setting one xNode to Passive, the first radio button. The second xNode will be configured with the IP address of
the remote “Passive” xNode in the “Connect To” field. Connection Status area provides diagnostic information of
the established link. When the connection is successful, the icons turn green and Stream active / RTSP OK status is
displayed. The Setup interface allow you to save six presets, which can be different remote nodes. Selecting a preset
is a fast way of changing the link destination.
© 2016 Axia Audio - Rev 2.0
<FIGURE 3-17>
If the node is connected to a network with firewall, in order to allow Unicast Link connections, TCP and UDP ports
listed on the WEB page need to be configured. The following ports are used:
TCP/554 RFC 2326 Real Time Streaming Protocol (RTSP)
UDP/7000 Livewire synchronization protocol
UDP/16384 Audio RTP stream to destination #1
UDP/16386 Audio RTP stream to destination #2
UDP/16388 Audio RTP stream to destination #3
UDP/16390 Audio RTP stream to destination #4
The basic setup establishes four bidirectional streams. If the needs are for less audio links, bandwidth utilization can
be reduced if the settings are customized. This is done by disabling unused channels through the Source page. The
setup wizard mention above would have set all source streams to standard stereo.
In Unicast Mode, the front panel presents the link status information as triangles below the meters.
• If no triangle is shown, the Source and Destination port is not configured for Unicast.
• If the triangle is blinking, the port is configured for Unicast, but there is no active connection.
3: The xNode in depth • 23
• When the triangle is displayed solid on, there is a Unicast Link established to that port.

Chapter Seven:
GPIO xNode
The GPIO xNode provides 6 DA-15 ports. Each port provides 5 GPI (opto isolated inputs) and 5 GPO (solid state
relays). Each port is capable of driving a combined current of 100mA. Each GPI pin should be limited to 20mA of
current.
The web interface provides configuration control as well as a real time view on each of the GPI and GPO pins
through a Java script in the web interface.

Using external power supplies is the recommended method in order to avoid possible ground loops between equipment.
Take note to use current limiting resistors per Figure: 7-3 if the voltage supplied is above 6vdc. The intention is to
limit the current to 20mA for each GPI pin. If the equipment being controlled is electrically isolated, than the use of
the GPIO port’s power supply is acceptable.

Figure 7-4
Axia GPIO accessory modules are designed to interface directly to the GPIO port. The DA-15 connector on the back
of an accessory module is a direct pin-to-pin match to the GPIO port of the xNode. Premade cables of this configuration are commonly available through companies that specialize in interconnect cable assembly products.
The GPO portion of the GPIO ports are solid state relays. Current should be limited to a combined 100 mA through
all the pins of a port. Maximum allowed voltage is 24 volts. The following diagram shows the recommended connections for outputs with the use of an external power supply.

Figure 7-5
If the device being controlled is electrically isolated, than the 5vDC supply can be used, maintaining a 100mA limit
on current drawn.
Figure 7-6
The Axia accessory modules use the 5vDC supply to illuminate LED based buttons. So a one-to-one pin connection
is all that is needed between any accessory modules and a GPIO port.
7: GPIO xNode • 33
Note that all of the inputs and outputs on a specific GPIO port are “grouped together”. The 5 “Outputs” are on 5
separate output pins, however, they share the same “Common Return” connection on Pin #7. Similarly, the 5 “Inputs” pins would be pulled to ground to activate them, and they share a common pin for a high-side rail, on Pin #10.
If more than one remotely-controlled device is to be connected to a single 15-pin I/O port, you must make sure that
the two units in question have the same ground potential or ground loops will occur. Therefore, it is recommended
that only one remote device be connected to each I/O port connector to assure complete electrical isolation.
Figure 7-7
Tid bit of worthless knowledge: The D-sub series of connectors was invented by ITT C orporation, in
1952. Cannon’s part-numbering system uses D as the prefix for the whole series, followed by one of A, B,
C, D, or E denoting the shell size, followed by the number of pins. Each shell size usually corresponds to a
certain number of pins: A with 15, B with 25, C with 37, D with 50, and E with 9. For example, DB25 denotes
a D-sub with a 25position shell size and a 25-position contact configuration which was common in the onset
of personal computers. When the PC serial port transitioned to the use of a 9-pin connector, they were often
labeled as DB9 instead of DE9 connectors, due to an ignorance of the fact that B represented a shell size. It
is now common to see DE9 connectors sold as DB9 connectors.

Simple Setup
The GPIO xNode has a simple setup page which provides access to the node ID (a node ID was likely already
assigned from the front panel at install) and configuration of the 6 GPIO ports. Included also in the page is a Java
script which provides status on each of the inputs and outputs.
Figure 7-8
Each port is represent by a row. The name column is used to assist with documenting the function of the port (or
the device which is connected to the port). The Channel column is used to configured the port. The input and output
columns show a grouping of boxes that represent each of the 5 GPIs and 5 GPOs. A high state (not active) is represented by a black box. A low state (active) is represented by a green state.
7: GPIO xNode • 34
Configuration of a port can be accomplished in three different ways.
1.
Port routing – The GPI activity on a port will trigger the GPO of the port you are configuring. (you are
routing the GPIs of a port to another port’s GPOs). This is done by entering in the IP address of the device
with a GPIO port followed by a forward slash and the port number. 10.216.0.121/5 – equates to port 5 at
address 10.216.0.121 new line 127.0.0.1/1 assigned to port 1 would be a loopback; GPI activity on the port
would trigger the GPO of the same port (used for testing)
2.
– The GPIO port will follow the logic as defined by a control surface. Axia control
surfaces have predefined logic for a source loaded to a fader. The logic is shared on the network through the
use of the unique channel number for a source. Refer to appendix A for common predefined functions. To
assign a port to a channel, either manually type in the channel number in the field OR use the browse button
to search the network for advertised sources.
3.
Pathfinder control – The Pathfinder series of products has the ability to observe GPIO activity as well as
trigger GPO activity. Nothing is required to configure in the GPIO xNode, all the configuration is done in
Pathfinder. Please refer to Pathfinder documentation for detailed information.

Other Web Interfaces
The GPIO xNode does not have any complexity to it, so there are no advance web pages to worry about.
Home
The Home page is the default page and provides information on the device ID, software version, system temp, network interface status, power supply status, and uptime. There is no sync information as in other xNodes because the
GPIO xNode is not an audio device and therefore does not require audio synchronization.
System
7: GPIO xNode • 35
The system page provides access to IP settings, logging options, password change, and software control. The system
page is covered in more detail in chapter 3, section Web Interface.

Chapter Eight:
Mixed Signal xNode
The Mixed Signal xNode has one switched analog input (either microphone or analog stereo), two analog stereo inputs,
one AES/EBU input, three analog stereo outputs, one AES/EBU output, and 2 GPIO ports (5GPI/5GPO per port).
Rear Panel
The Mixed Sigal xNode uses RJ45 connectors for analog and AES audio, and an XLR connector for the selectable
Mic input.
Figure 8-1: GPIO xNode Rear Panel
The top 4 RJ-45 style ports are inputs; three analog inputs followed by one AES/EBU input. The bottom 4 RJ-45
style ports are outputs; three analog outputs followed by one AES/EBU output.
The XLR-F connector is used as an analog input with the intention of it being a microphone input.

Appendix C:
AES67
AES67 standard defines an interoperability mode for transport of high­performance audio over networks based on
the Internet Protocol. For the purposes of the standard, high­performance audio refers to audio with full bandwidth
and low noise . These requirements imply linear PCM coding with a sampling frequency of 44,1 kHz and higher and
resolution of 16 bits and higher. High performance also implies a low­latency capability compatible with live sound
applications. The standard considers latency performance of 10 milliseconds or less.
xNodes implementation is compliant with the standard supporting interoperability with third party devices. In
particular, the following features are implemented:
• Multicast and unicast Real Time Protocol (RTP) audio streaming
• Session Initiation Protocol (SIP) based connection management for unicast streams
• Transmission of 1ms audio frames in linear PCM 24­bit format
• Ability to receive audio streams containing 1 through 8 channels
• Ability to receive 16­bit as well as 24­bit format
• Support of IEEE1588­2001 Precision Time Protocol standard
• Timestamping outgoing stream with IEEE1588 derived RTP timestamps
Network synchronization setup
AES67 standard requires device to use IEEE1588 network time protocol standard. The Synchronization and QoS
page of the xNode provides the controls to establish the xNode as a system PTP master or slave to a grand master.
Clock mode options allow selecting the operation suitable to the system in which the xNode is being deployed.
• PTP/IEEE 1588 ARB clock class 248 mode allows the node to be a master when no better clock is available
on the network. Since xNodes are not locked to GPS or any other high precision source, only Arbitrary (ARB)
Clock class is provided.
• PTP/IEEE 1588 slave only is recommended for networks with high precision grand masters present.
• Additional options are same as above with Livewire master conditions to allow the xNode to act as a gateway for
synchronization to Livewire legacy products.
C: AES67 • 50
PTP domain number should be selected to 0 unless there is a need for multiple clock domains on a network segment.
PTP delay mechanism specifies how the node determines network round trip latency. This setting MUST match the
master clock setting. In practice, End­to­End (E2E) is always used by ordinary clocks and boundary clocks. Peer­to­
Peer (P2P) mechanism was defined to limit amount of traffic reaching the master clock, but is rarely used.
PTP clock priority1/priority2 numbers provide a control over master clock selection. Lower priority number makes the
clock a preferred choice over devices with a higher number. The range is 0­255, and 128 is the default and middle value.
© 2016 Axia Audio - Rev 2.0
PTP clock sync interval determines how often clock packets are sent. The faster those packets are sent, the faster and
more accurate synchronization can be achieved. Some IEEE1588 devices do not support lower clock sync interval
than 0.5s, so this setting may need to be adjusted depending on what other networking equipment is used. AES67
recommends an interval of 1⁄8 (8 packets per second). This setting affects behavior of the master clock and does
nothing when the node is a slave.
AES67 Multicast connection setup
xNode transmits a multicast streams as soon as Source is configured with a Livewire channel number or multicast
IP address and Stream Mode is set to a value other than “disabled”. AES67 requires devices to support reception of
at least 1ms frames ­this corresponds to “Low Latency Stereo” Stream Mode setting. Other settings will work if the
receiver supports different frame sizes in addition to the required 1ms.
Figure App-1: Example of a 2-channel, 24-bit, 1ms frame, multicast stream to group 238.194.0.1
The Session Description (SDP) can be downloaded from xNode by clicking on the ‘AES67: Download stream
description (SDP)” link.
In order to receive AES67 multicasts stream the multicast address of the stream would be enter into the Channel/
Address field of the Destination page.
C: AES67 • 51
Figure App-2: Example of receiving a multicast stream
This method of configuration for multicast reception requires the source to transmit in PCM 24­bit stereo or 8­channel
format. To receive other forms, follow the multicast group with information about the stream as follows:
{multicast group};{bit rate}/{sample rate}/{channels}
238.194.0.2;L16/44100/2
Surround 8­channel reception is set up by selecting Destination Type: Surround.
Channel/Address field accepts optional UDP port number following IP address, separated with a “:”. This is useful
option when the port number is different than RTP default 5004.
© 2016 Axia Audio - Rev 2.0
AES67 Unicast Setup
Each Source of an xNode can be configured as a multicast sender, or unicast port supporting a single listener/
receiver. Unicast configuration is achieved by clearing the Channel/Address field in the Source page setup.
Figure App-3: Example of source configuration for unicast mode.
The media stream is accessed using a SIP URI (Session Announcement Protocol Uniform Resource Identifier). It
contains “sip:” prefix, followed by Source/Destination port number, ‘@’ sign and IP address of the node.
The xNode provides the address on the Sources WEB page so it can be copied conveniently. This can be found next
to the AES67 text. In the figure 3 example, the text to be copied is sip:1@192.168.100.72.
In Unicast mode, Source accepts SIP connections. There are a few possible scenarios:
• Receive­only connection (SIP Invitation with recvonly attribute specified in the SDP block). After answering,
xNode will start sending stream to the originator of the connection. Media format follows current Source
configuration.
• Send­only connection (SIP Invitation with sendonly attribute specified in the SDP block). After answering,
xNode will start receiving the stream which can be 16­bit or 24­bit with channel count from 1 to 8. This type of a
connection required the corresponding Destination to be not configured (empty Channel/Address) field.
• Bidirectional (default SIP invitation). xNode will receive and send. The media format must be 24­bit. This type of
a connection required the corresponding Destination to be not configured (empty Channel/Address) field.
In order to setup AES67 Unicast stream receive, enter the SIP URI stream address in Channel/Address field of a
destination.
C: AES67 • 52
Figure App-4: Example of unicast receive setup
© 2016 Axia Audio - Rev 2.0
The xNode makes a SIP call to the specified source. The call is receive­only (issued with recvonly SIP/SDP media
attribute specified).
The xNode will provide status of the unicast connection on the front panel. Small triangle icons below the meters
show the current status:
• If no triangle is shown, the Source and Destination port is not configured for Unicast.
• If the triangle is blinking, the port is configured for Unicast, but there is no active connection.
• When the triangle is displayed solid on, there is a Unicast Link established to that port.
C: AES67 • 53
Channel/Address field accepts optional UDP port number in the URI, separated with a “:” from the address part.
This is needed when the port number used by sender is different than SIP default 5060.
