Dante Network Setup
Dante Controller auto-discovers all Dante devices on the network and advertises itself to allow other Dante-enabled devices to
communicate with it. The default device name is the model number followed by the last six digits of the MAC address of the
device. Multiple devices on the same network can present difculty identifying inputs and outputs. To avoid confusion, each
device must be renamed 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.
Rename an AXP50CAT:
Ensure the control computer and a single AXP50CAT are connected to the same network (see Control Connection on page2).
1. From the start menu select All Programs >Audinate >Dante Controller >Dante Controller.

time, remain in Emulate mode.
b. To push a conguration to the device, pull a conguration from the device, or to
make immediate changes to the conguration or operation, select Live mode.
NOTE: Changing from Emulate to Live mode opens the Connect to
device... dialog. Select the connection and follow the on-screen prompts.
The main screen provides access to all the features of the AXP50CAT. Full details
about using the software are found in the AXP50CAT User Guide on the Extron
website or in the DSP Congurator help les.
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.

AXP50CAT • Setup Guide (Continued)
Creating a Physical Dante Network
A physical network is required to share Dante audio channels between AXP50CAT devices and a DMP128 AT. Both the
AXP50CAT and DMP128AT contain a 4-port Gigabit switch with four RJ-45 connectors located on the back panel that accepts
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 topology places one DMP128AT as the central unit, which connects directly to up to three more units. Alternatively,
a larger network switch in place of the central DMP128AT, allows more than four AXP50CATs to connect in the star
conguration (see gure 7).

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
Select Devices
After the inputs of the AXP50CAT are congured, they must be routed to the
other Dante devices on the audio network.
Dante Controller is required.
1. Ensure the control computer and AXP50CAT are connected to the same
network (see Control Connection on page2).
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 the DMP128 in the Dante Receivers column to
show all device inputs.
4. Click the +box next to the AXP50CAT in the Dante Transmitter row to
