Star Topology Without Redundancy; Star Topology With Redundancy - AMX Enova DGX 100 Series Hardware Reference Manual

Star Topology without Redundancy

Dante ASB Input and Output boards are connected to a common network (via the Dante Primary Ethernet port) with or
without other Dante devices. The Dante network is available to both send and receive to and from Dante ASB Inputs and
Outputs.
Control of signal paths into and out of the Enova DGX is provided by the System Configuration interface (see page 137)
while control of signals paths to and from the Dante network is available through Dante Controller software (available at
www.audinate.com). Using the star topology requires changing the configuration in Dante Controller (Network
Configuration Tab > toggle Redundant/Switched) which is followed by a power cycle of the Dante ASBs.
Each Audio Switching Board in the enclosure is connected via the Dante Primary Ethernet port to a common network

Star Topology with Redundancy

Dante ABS Input and Output boards are connected in exactly the same configuration as above, except that there is an
additional connection via the Dante Secondary Ethernet port on each board to a second network. Direct control of the
secondary (redundant) network is not possible while the primary network is active, though all commands sent throughout
the primary network are automatically applied to the secondary network. If the primary network experiences an outage,
the secondary network automatically routes to cover the outage until the primary network is brought back online. Using
the star topology requires changing the configuration in Dante Controller (Network Configuration Tab > toggle
Redundant/Switched) which is followed by a power cycle of the Dante ASBs.
In addition to each Dante Audio Switching Board being connected via the Dante Primary Ethernet port to a common
network, each Dante ASB is connected via the Dante Secondary Ethernet port to a second network - the primary and
secondary networks must not be connected (FIG. 68):
