Creating a Physical Dante Network
A physical network is required to share Dante audio channels between a Dante source
device and a NetPA AT. The NetPA 502 AT and NetPA 1001-70V AT have an RJ-45
connector located on the back panel that accepts a standard network cable.
A DMP 128-based Dante network can be configured in a star or daisy chain network
topology using the four port switch and the Dante Controller in switched mode.
Star network topology places one DMP 128 C 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 NetPA ATs to connect in the star configuration.

A daisy chain configuration can also be used. Each NetPA AT device can only connect to
the end of the chain.

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).
NOTE:
At the moment, Dante is not compatible with EEE (Energy Efficient Ethernet)
technology. Care should be taken when using a network switch with this technology in
a Dante network.
•
If using a managed switch, ensure that it supports disabling EEE on all ports that
will be used for Dante traffic.
•
If using an unmanaged switch, do not use models that support the EEE function, as
it can not be disabled on these models.
