About Connections
There are two ways to connect the Rio-D2 to a Dante
network.
NOTE
A daisy chain connection is suitable for a simple system
with a small number of devices.
Use a star network if a large number of devices are
connected.
Daisy Chain Network
A daisy chain is a wiring scheme in which multiple devices
are connected together in sequence. In this way,
networking is simple and requires no network switches.
If you connect a large number of devices, you must set a
higher latency value to avoid skipping audio that could be
caused by an increased delay in signal transfer among the
devices. Also, if a connection is broken in a daisy chain
network, the signal flow is interrupted at that point and no
signal will be transferred beyond that point.
Star Network
In a star network, each device is connected to a central
network switch. Using a GbE-compatible network switch
enables you to configure a wide-band, large-scale network.
We recommend a network switch that features various
functions to control and monitor the network (such as Qos,
the ability to assign priority to data flows - e.g., clock
synchronization or audio transmission on certain data
circuits.)
With this topology, it is common to configure a redundant
network so that an unexpected network problem will not
affect any audio or otherwise stable communications.
About Redundant Networks
A redundant network consists of two circuits, a primary
circuit and a secondary circuit. Normally, the network
operates on the primary circuit. However, if the primary
connection is broken, the secondary circuit will
automatically take over communications. Therefore, using
a redundant network with a star topology would increase
communication stability relative to a daisy chain network.
