1 –Overview
Figure 1 - unAX4I Front Panel
The unAX4I AES67 audio interface is a cost effective XLR IO wall
plate solution. The unAX4I features four balanced mic/line XLR
inputs and two balanced line outputs do de-pluggable connectors
on the side of the unit. All inputs and outputs can be used
simultaneously and all audio channels are available separately on
the audio network. The unAX4I is designed to fit into all dual gang
US junction boxes, mud rings, and old work brackets. The unAX4I
is PoE enabled, so all connectivity (power, control and data) is
provided by a single CAT-5/6 cable. The unAX4I’s size and I/O
density make it easy to put AES67 connectivity whenever it’s
needed.
Attero Tech unIFY Control Panel application can be used to
configure the device-specific features. It is also used to configure
its AES67 transmit and receive streams as well.
The unAX4I also supports control by third party systems allowing
external configuration of its settings such as phantom power and
input gain in real time. Further information on 3rd party control
can be found later in this document in section 3.
1.1 –What’s in the Box

*Note: The unAX4I has a label on the front of the metal housing
at the top that shows the devices MAC address. This is important
for initial device identification as these digits make up part of the
devices default network name. The MAC address is also given on
the back of the unit.
2.1 –Mounting
A typical installation will involve mounting the wall plate into a
pre mounted wall box or mounting bracket. Before installation,
make sure the wall box where the unAX4I is to be installed is pre-
wired with a suitable cable back to a PoE-enabled network switch
or mid-span injector. If a mid-span injector is being used, the
cable should be connected to the port that supplies both Ethernet
and power (refer to the devices manual if unsure which port is
which).
Attach the network cable from the switch/mid-span injector to the
Ethernet port of the unAX4I. If the switch or mid-span injector is
already running and PoE is enabled, the unit should power up and
the green ID LED on the front of the device should turn on.
With the cable attached, carefully place the unAX4I into the wall
box taking care to not trap the cabling. Once full in place, secure
it with the screws provided. Once the unit is secured in the wall
box, fit the Decora plate and secure it with the screws provided
with it.
The figure below shows the installation of the companion passive
unXP2O XLR audio output plate and the unAX4I.

2.2 –Error Reporting
The unAX4I is equipped with error reporting features. Upon
power up, the front panel power LED will briefly light red and then
change to green if the device boots successfully. If the LED
remains on solid red, this indicates a device failure. If power
cycling the unit does not correct this problem, contact Attero
Tech technical support.
2.3 –Hardware Connections
The unAX4I provides balanced inputs and outputs to external
analog audio equipment. Refer to the following diagrams for
connecting different types of audio devices to the inputs and
outputs of the unAX4I. Professional grade audio cabling is
recommended to achieve the best audio performance
throughout the system.

3 –Device Configuration
There are two parts of the device that require software to setup.
First the audio routing, and second the configurable features of
the device itself.
Configuration of the unAX4I specific features is carried out using
the Attero Tech unIFY Control Panel application. This application
is available from the Attero Tech website (www.atterotech.com).
It should be used to examine and modify the device specific
features such as mic/line gain settings, and phantom power.
The audio routing is also done using Attero Tech’s unIFY Control
Panel. There is a tab on the devices configuration for each unit
specifically for setting up receive and transmit streams.
*Note: When using unIFY Control Panel, the unAX4I will be shown
using a default device name of unAX4I-###### where ‘######’ is
the last six characters of the devices MAC address.
3.1 –IP Address Setup
*************************IMPORTANT****************************
Failure to correctly configure IP addresses will not allow a unAX4I
device to correctly authenticate in the unIFY Control Panel
software, the devices parameters will not be available, the input
and output channels also won’t be visible and routing of audio to
and from the device will not be possible.
*******************************************************************
In order to configure a unAX4I, both to set up internal parameters
and also setup audio routing, the PC/Mac will need to be able to
communicate with the devices over the network. While all AES67
devices will be discovered regardless of the IP address setup on
the PC or Mac, communication can only occur if the PC/Mac and
the device have compatible IP addresses.
By default, the unAX4I is set to get a dynamic IP address. Like
almost all network devices, if the unAX4I does not find a DHCP
server to retrieve an IP address from, it will give itself an local link
address sometimes also known as an automatic private IP address
(APIPA) instead. A local link IP address is always in the range
169.254.x.y.
To ensure communication, the PC/Mac can either be set to get a
dynamic IP address, or be given a static IP address in the range
169.254.x.y. The PC may require a restart if its IP address is
changed for the change to take effect.
In some applications, IP addresses of devices may need to be set
to something specific and that can be done once initial
communication has been established. Bear in mind however that
if a static IP address is assigned to a device and that static IP
address is in a different range to the IP it was previously using to
communicate with the PC/Mac, the PC/Mac will lose
communication with the device until such time as the PC/Mac IP
address is also changed to an IP in range of the devices new IP
address.
3.2 –Factory Reset
**************************IMPORTANT****************************
The factory reset returns the entire device to its factory defaults.
Using this feature will mean all custom AES67 settings and all
audio power-on default settings will be cleared.
*******************************************************************
*NOTE: The factory reset is a useful way of quickly restoring
communications with a device which has an unknown static IP
address as a factory reset returns the device’s network settings
to getting a dynamic IP. Having successfully completed a factory
reset of the device, setting the PC’s IP address to also obtain a
dynamic IP address should then allow the PC to communicate fully
with that device.
Access to the factory reset button is through a small circular hole
on the underside of the unit, next to the ventilation cutouts.
To use the factory reset, insert a small screwdriver or paperclip
into the hole to activate the factory reset switch. There should be
a noticeable “click” when it’s activated. Hold the switch in for 5 to
10 seconds then release. If the factory reset was successful, the
unit will reset and is indicated by the power LED will turning red.
3.3 –Firmware Updates
The unAX4I has the ability to be updated in the field. Updates are
applied via the network using Attero Tech unIFY Control Panel’s
Smart Firmware update facility. The latest unAX4I SFU file is
available from the Attero Tech customer portal.

3.4 –3rd Party Control
The unAX4I supports 3rd party control allowing external system to
manage the unAX4I’s settings such as phantom power, mic/line
gain options and control of presets. The interface which is
available to anyone to use with any device capable of sending and
receiving UDP messages.
Information on the commands the unAX4I supports as well as
details of how to use the 3rd party UDP interface can be found in
the unIFY 3rd party Software API document, available from the
registered users section of the Attero Tech website (Go to
www.atterotech.com and click on the log-in option).
3.5 –Using the Command interface
In order to make use of the control interface the unAX4I and the
controlling device need to be on the same physical subnet and
need to have IP addresses in the same range. The control devices
should then be able to converse with the unAX4I without any
further configuration necessary.
