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.

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 difculty
identifying inputs and outputs. To avoid confusion, rename
each device to a unique identier.
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 aDante
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.

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 nd 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).
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).

AXP64CAT • Setup Guide (Continued)
Loading Building Blocks
The discrete signal paths can be individually loaded with pre-congured, modular templates called building blocks. These blocks
are designed for specic microphones, source devices, analog and digital inputs, and can streamline initial conguration. The
building blocks contain conguration parameters tailored to a selected input device.
Loading a building block congures each block in the signal path with pre-determined parameters to match the selected device
characteristics. Although tailored for the specic 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-congured processor and gain block parameters. Processor blocks are initially bypassed.
3. 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).
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 congured 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 gure 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 conguration.

Figure 5. 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 congured, they must be routed to the other Dante devices on the audio network. To do
this, use Dante Controller.
