Figure 34. Daisy Chain Network Topology
Hybrid versions combining the star and daisy chain topologies can be used, but a ring topology or any topology
that creates a duplicate connection causes a failure in Dante Controller. Redundant connections are possible
using the primary and secondary port interface structure (see Redundant Configuration for more details).

Redundant Configuration

In redundant mode, the 4-port AT switch (see
ports that duplicate audio traffic. Ports 3 and 4 are marked
for secondary. Primary and secondary switches cannot be connected together anywhere in the audio network.
Redundant configuration can be enabled using Dante Controller or DSP Configurator.
To configure the DMP 128 Plus AT in redundant mode using Dante Controller:
1. Open Dante Controller.
2. Press <Ctrl+D> on the keyboard to access the Device View dialog box.
3. Select the desired DMP 128 Plus AT from the (Choose a Dante Device...) drop-down menu (see
figure 35, ).

4. Select the Network Config tab (
5. From the Dante Redundancy panel, use the drop-down to select Redundant (
NOTE: To configure the DMP 128 Plus AT in redundant mode using DSP Configurator, refer to the DSP
Configurator Help File.
