Creating a Physical Dante Network

Basic Configuration

A physical network is required to share Dante audio channels between DMP 128 AT
devices. Each DMP 128 AT contains a 4-port Gigabit switch with four RJ-45 connectors
located on the back panel to accept standard network cables. The 4-port switch can
operate as a standard switch described in this section or in redundant mode (see
Redundant Configuration
during a single network failure, preventing audio stream interruption.
NOTE: The Dante Controller network configuration defaults to switched mode (basic)
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 topology has one DMP 128 AT as the central unit, which is then directly
connected to up to three other units. Alternatively, a larger network switch can be used in
place of the central DMP 128 AT, allowing more than three units to be connected in the star
configuration (see figure 85).

A daisy chain configuration can also be used. Each unit is connected to both the previous
unit and the next unit in the chain (see figure 86).

Hybrid versions combining the star and daisy chain topologies can also be built, but a ring
topology, or any topology that creates a duplicate connection causes a connection failure in
the Dante Controller software. Redundant connections are possible using the primary and
secondary port interface structure (see
NOTE: Connections between DMP 128 AT ports in either a star or daisy chain network
on page 118) that switches between duplicate audio streams
making star and daisy-chain configurations possible. When configured for redundant
operation, different connection rules apply (see
page 118).
