Connecting the AXP 64 C AT to a Network
The AXP 64 supports 100 and 1000 Mbps half duplex and full duplex connections. You can use either a straight-through Ethernet
cable or a crossover cable to connect the AXP to a network via one of the four AT ports (see figure 1, E, on page 1). The control
device must be connected to the same network. Any one of the four AT ports can be dedicated as a control connection. If you do
not know the IP address of the control device, use Dante Controller to obtain it (see Finding a Dante Device Address on page 6).
When all connections are made and power is applied, the green (activity) LED of the connected AT port blinks to indicate data
activity on the connection.

Downloading and Installing Dante Controller and DSP Configurator Software

Setting Up the Dante Network
Communication between the AXP 64 C AT and a controlling device or a computer running software such as Extron DataViewer via
a TCP socket using port 4333. Use a standard Ethernet cable to connect the AXP to a network via one of the four RJ-45 AT ports
(see figure 1, E, on page 1).

Renaming an AXP 64 C AT
Dante Controller auto-discovers all Dante devices on the network and advertises itself to allow other Dante-enabled devices to
communicate with it.
NOTE: The default device name is the model number followed by the last six digits of the MAC address of the device (located
on a sticker on the rear panel).

Multiple devices on the same network can present difficulty
identifying inputs and outputs. To avoid confusion, rename
each device to a unique identifier.

NOTE: To simplify renaming, connect only one Dante
device to the network at a time. As each device is
renamed, it can remain connected.

1.

Ensure that the control computer and a single unnamed
AXP 64 C AT are connected to the same network.

2.

From the start menu select:
All Programs > Audinate > Dante Controller >
Dante Controller.

The Dante Controller - Network View screen
opens. All Dante devices on the network are discovered
and listed.
3.

From the Device menu, select Device View.

4.

The Dante Controller - Device View dialog
opens. Select your device from the (Select a Dante
Device...) drop-down list.

NOTE: If there are multiple AXP 64s connected to the network that have not been renamed, to identify an individual

device you must obtain the media access code (MAC) address of the desired device from the label on the rear panel.

The Device View dialog populates with the selected AXP 64 C AT information.

5

AXP 64 C AT • Setup Guide (Continued)
5.

8.

Click Yes to enter the new name, then close the Device Configuration dialog box.

The new name is written to the AXP 64 C AT. Repeat as necessary for all AXP 64 C AT devices.

NOTE: After the AXP 64 C AT is renamed, it can remain connected to the network. However, subsequent devices must be
connected one at a time and renamed before the next device is connected.

Finding a Dante Device IP Address
To find the IP address of a Dante device, you need the name of the device (see Renaming an AXP 64 C AT on the previous
page).

NOTE: If the AXP 64 has not been renamed, its default name consists of the product name followed by a hyphen (AXP64-)
plus the last 6 digits of the unit MAC address (for example, AXP64-040C06).

6

1.

Open Dante Controller for Windows (see Renaming an AXP 64 C AT).

2.

On the Dante Controller main screen, click the Device Info tab (1).

3.

On the Device Info screen, locate the name of your AXP. The IP address is in the Primary Address column (1).

4.

Connect the AXP to a computer (using a host communication utility such as Extron DataViewer) or to a control system.

5.

Select a TCP/IP connection and enter the IP address of the AXP 64 where indicated. Enter 4333 for the port number.

Product Category

Configuring the AXP 64 C AT
After the device is named, use the DSP Configurator to configure the AXP 64 C AT as desired.
1.

Ensure the control computer and AXP 64 C AT are connected to the same network and that the AXP 64 C AT is renamed for
identification (see Renaming an AXP 64 C AT on page 5).

2.

Start the DSP Configurator software. From the drop-down list on the opening page, select AXP 64 C AT and press OK.
The main screen opens. The main screen provides access to all the features of the AXP 64 C AT. Full details about using the
software are found in the AXP 64 C AT User Guide on the Extron website or in the DSP Configurator help files.

3.

The program starts in Emulate mode. Select the appropriate operating mode as follows:
•

To create a configuration offline to upload (push) to the AXP 64 C AT at a
later time, keep the AXP in emulate mode.

•

To push a configuration to the AXP, pull a configuration from the device, or to
make immediate changes to the configuration or operation, click the Live
button to place the AXP in Live mode.

NOTE: Changing from emulate to live mode opens the Connect to
device... dialog box (shown at right). Select the device in the
Dante Devices panel.

AXP 64 C AT • Setup Guide (Continued)
Loading Building Blocks
The discrete signal paths can be individually loaded with pre-configured, modular templates called building blocks. These blocks
are designed for specific microphones, source devices, analog and digital inputs, and can streamline initial configuration. The
building blocks contain configuration parameters tailored to a selected input device.
Loading a building block configures each block in the signal path with pre-determined parameters to match the selected device
characteristics. Although tailored for the specific device, the processing blocks can still be customized, if necessary.
To load a building block:
1.

Click the input number. The Building Blocks dialog opens.

2.

Choose a building block that best describes the connected input device. As the pointer moves over the selection, the text is
underlined. Click the selection to load the block.
The building block loads pre-configured processor and gain block parameters. Processor blocks are initially bypassed.

If necessary, further customize the processor blocks according to the requirements of the system (see the AXP 64 C AT User
Guide on the Extron website).

3.

Creating a Physical Dante Network
A physical network is required to share Dante audio channels between AXP 64 C AT and devices such as the DMP 128 AT. The
AXP 64 C AT and the DMP 128 AT each have a four-port switch with four RJ‑45 connectors located on the back panel that accept
standard network cables. A DMP 128‑based Dante network can be configured in a daisy‑chain or star network topology using the
four-port switch and the Dante Controller in switched mode.

Star Network
Star network topology places one DMP 128 AT as the central unit, which connects directly to up to three AXP units (see figure 4).
Alternatively, a larger network switch in place of the central DMP 128 AT allows more than four AXP 64 C ATs to connect in the
star configuration.

Daisy Chain Topology

Hybrid versions combining the star and daisy chain topologies can be built, but a ring topology, or any topology that creates a
duplicate connection causes a connection failure in Dante Controller.

NOTE: Connections between ports in either a star or daisy chain network do not need to be sequential (1 to 2, 2 to 3, 3 to 4),
nor do they need to be made between the same port numbers (1 to 1, 2 to 2, 3 to 3, 4 to 4).

Dante Operation
Selecting Devices
After the inputs of the AXP 64 C AT are configured, they must be routed to the other Dante devices on the audio network. To do
this, use Dante Controller.
1.

Ensure the control computer and AXP 64 C AT are
connected to the same network.

2.

From the start menu select:
All Programs > Audinate > Dante Controller >
Dante Controller.
The Dante Controller - Network View screen opens.
Dante Controller auto-discovers Dante devices on the
network and advertises itself to allow other Dante-enabled
devices to communicate with it. Device inputs are Dante
receivers (listed vertically on the left) and device outputs
are Dante transmitters (listed horizontally across the top).
Transmitters (outputs) connect to receivers (inputs) using
the connection matrix.

3.

Click the + box next to any Dante device in the Dante
Receivers panel, (such as the DMP 128 (1 in the
example at right) to show all device inputs.

4.

Click the + box next to the AXP 64 C AT (2) in the Dante
Transmitters panel to show all device outputs.

9

Routing Inputs and Outputs
1.

Click the + box next to the input channels (receivers) on
another Dante device (DMP128-Rack01 DIGITAL_IN-01
in the example at right).
All device outputs (transmitters) display horizontally.

2.

Click the junction of the desired connection (1).
Example: AXP64-Lab OUTPUT-01 to
DMP128-Rack01 DIGITAL_IN-01 (shown at right).
A check mark at the junction indicates the connection is
made. A check mark is also placed next to the receiver
channel.

NOTE: An input (receiver) can connect to only one
output (transmitter). An output (transmitter) can
connect to multiple inputs (receivers).

3.

Click the junction again to disconnect the input from the
output.

Additional AXP 64 C AT outputs (Dante transmitters) can
be connected to or disconnected from other Dante device
inputs (Dante receivers) using the same method (see the
