User Manual

1 – Overview

The unD4O Dante™/AES67 audio interface is a cost effective 4 channel analog break-out box and is designed in a small
flange-mount form factor for broad market application. Its size and I/O density make it easy to put Dante™ / AES67
connectivity wherever it’s needed – on a rack shelf, under a table or near the destination equipment – thereby eliminating
costly and interference prone analog wiring and power supplies.

Figure 1 - unD4O Overview

The unD4O features four electronically balanced line-level outputs. All outputs can be used simultaneously and all audio
channels are available separately from the Dante network.

Connection to the Dante™/AES67 network is provided by a single Ethernet RJ45 connector on the back of the unit. The
unD4O is PoE-enabled which allows the unD4O to be powered over its network cable from a suitable PoE source (IEEE

802.3af) or from a locally connected 24V DC power supply (sold separately). This is particularly useful as the unD4O can
then be mounted in remote location where access to a mains outlet would be limited or indeed, non-existent.

Audinate’s Dante™ Controller or other 3rd party manufacturer's Dante™ routing software can be used to control the audio
routing configuration of the device along with enabling of AES67 streams.

1.1 – What’s in the Box

The device comes supplied with the following:

o (1) unD4O
o (4) 3-position Phoenix plug connectors

1.2 – Option al Extras

The following are available as options for the unD4O and that may be ordered separately:

*Note: The unD4O has a label on the flange of the metal housing that shows the devices MAC address. This is important
for initial device identification as the last six digits make up part of the devices default network name that is shown when
the device is detected by Dante™ Controller. The full MAC address is also given on the back of the unit.

1.4 – Mounting and Installati on

It is recommended that the unit be secured to a flat surface with a screw through each mounting flange. Dimensions for
mounting are show in the Error! Reference source not found. below. Use a No. 6 screw of a type and size that is
applicable to the surface to which the device will be attached.

Figure 2 - Mounting Information

o Attach the PoE + Data Dante™/AES67 INTERFACE port to a spare PoE-enabled port on a PoE switch using a CAT-

5 cable. If a midspan injector is being used, connect a spare input port to the Dante network switch using a CAT­5 cable, and then connect the corresponding output port to the PoE + Data Dante INTERFACE of the unD4O.

o Attach any audio sources that will be used to the inputs. The inputs are balanced so be sure to check what

output type the source to be connected uses in order to find how to connect it correctly (see Hardware
Connections section).

If all steps are performed correctly, the power LED on the front should be lit. There may also be some activity on the
Dante™/AES67 INTERFACE LED indicators. With no Dante™/AES67 network, both LEDs will remain off. If an active
connection is made both LEDs will come on and if there is network activity, the yellow LED will then flash.

*Note: All Attero Tech products are tested using UTP cabling and it is recommended that UTP cabling be used when
installing them. STP cabling can be used for installation though care must be taken not introduce grounding issues into
the system by doing so.

1.5 – Error Reporting

The unD4O 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. Additionally, the unD4O has
three status indictor LEDs for showing various device
states. The following figures show these states and
associated descriptions.

1.6 – Status LEDs

The front panel LED’s show the Dante™/AES67
diagnostic status. If network or audio problems persist,
these LED’s may assist in identifying issues.

The LED’s are POWER, SYS, ERR and SYNC and the color
of each LED has different meanings. The tables below
show the combination and what each combination
means.

1.7 – Hardware Connections

The unD4O provides balanced audio outputs for connectivity to external analog audio equipment. Refer to the following
diagrams and instructions for connecting different types of audio devices to the outputs of the unD4O. Professional grade
audio cabling is recommended to achieve the best audio performance throughout the system.

1.7.1 – Balanced Output to an Unbalanced Input

Connect the positive terminal of the unD4O output to the signal input or “Tip” of the unbalanced analog input. Connect
the unD4O GND connection to the sleeve connection of the unbalanced input.

2 – Device Configuration

The audio routing and enabling of Dante™/AES67 audio streams should be carried out using Audinate’s Dante™
Controller. This can be obtained from the Audinate website (www.Audiante.com
and about setting up routes on a Dante network can also be found on their website.

*Note: When using Dante™ Controller, the unD4O will be shown using a default device name of “unD4O-######” where
‘######’ is the last six characters of the devices MAC address.

2.1 – IP Address Setup

******************************************************** IMPORTANT ******************************************************

Failure to correctly configure IP addresses will not allow an unD4O device to show up correctly in Dante™ Controller. The
unD4O will appear but its device information won’t be visible. It’s output channels also won’t be visible and routing of
audio to the device will not be possible.

*****************************************************************************************************************************

In order to configure an unD4O, both to set up internal parameters and also setup audio routing, the PC will need to be
able to communicate with the devices over the network. While all Dante™ devices will be discovered regardless of the IP
address setup on the PC, communication can only occur if the PC and the device have compatible IP addresses.

By default, the unD4O is set to get a dynamic IP address. As with all Dante™/AES67 devices, if the unD4O 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 can either be set to get a dynamic IP address, or be given a static IP address in the
range 169.254.x.y with a subnet mask of 255.255.0.0. The PC may require a restart if its IP address is changed for the
change of IP 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. The uD4O does support static IP addresses but 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, the PC will then lose communication with the device when it’s rebooted until such time as the
PC’s IP address is also changed to an IP in range of the devices now new IP address.

Further information on IP setup for an audio system using Dante™ can be found in the FAQ’s on the Audinate website
(https://www.audinate.com/resources/faqs

).
