System Examples
The examples below show typical uses for the connection of Dante network(s) to an Enova DGX via the Dante Audio Switching
Boards. Enova DGX systems with Dante Audio Switching Boards are designed to route audio through the system in three ways:
Daisy Chain Topology (default) – Dante ASB Input and Output boards are connected one to the other through the system,
reducing cable requirements. Using the daisy chain 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.
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 173) 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.
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.
Daisy Chain Topology
An Ethernet cable from a network switch (connected to any other Dante devices) connects to the Dante Primary Ethernet port on
the Dante ASB Input board then a second run connects from the Dante Secondary Ethernet port on the Dante ASB Input board to
the Dante Primary Ethernet port on the Dante ASB Output board.
In an Enova DGX 6400, the routing path is: network switch > left input board > right input board > left output board > right output
board.

IMPORTANT: In daisy chain
topology, Dante ASBs must be
segmented from other Dante
devices such that the run
originating from a Dante
network switch travels directly
to the first Dante ASB in the
enclosure and concludes with
the last Dante ASB in the
enclosure.
