APPENDIX B: Dante Network Setup

Introduction

Installing the iAM-SUM into an existing and functioning Dante network is virtually
plug and play. The iAM rear panel AoIP jack supports 1Gb/s and 100Mb/s Ethernet
devices in Dante Audio over IP network configurations.
The AoIP option on the iAM-SUM supports Hitless and has 2 RJ-45 interfaces, a
primary interface and a secondary interface.
Additionally, an SFP slot is provided to receive the AoIP signal using network fiber
SFPs. These are 1G SFP slots. The SFP slot always acts as a primary interface.
On iAM-SUM, the AoIP source can be selected through the Source Select option.
The iAM-SUM is set up at the Wohler factory to be used as a slave rather than a
master within the Dante network. Other devices or software, such as a Dante
Controller, are expected to be responsible for most device configurations and all
audio routing.
Please refer to the Dante Controller User Guide or other control device
documentation for specific network and device setup information. The next section
provides a guide to configuring the card and AOiP port.

What is in the iAM-SUM for Dante?

The Dante AOIP option consists of an Audinate Brooklyn II card directly connected
to the AOIP port. This port is dedicated to the card and should not be confused
with the Wohler unit Management port. These two ports must be on two different
subnets, one for the AOIP network and the other for access to the Wohler Web GUI
for management of the Wohler unit itself. Either one can be configured to have
static or DHCP addresses. The Wohler Web GUI indicates the presence of the Dante
card and the AOIP license but does not provide access to the various configuration
parameters internal to the card. The speed of the AOIP port is 1G default or
100Mbps.
The Audinate® Brooklyn II card has a simple process to set its initial IP address.
The initial factory setting for the card's AOIP port is DHCP. When connected to a
DHCP based Dante network and the unit powered on, the Dante card sets the DHCP
server provided address as its default address.
Therefore, if the Dante network has a DHCP server, the unit can be inserted into
the network and can be configured further using the Audinate application, Dante
Controller, running on a host on the same DHCP based subnet.
If the Dante network is static based or if DHCP fails, the card sets a static Link Local
arbitrary address in the format 169.254.x.y, where x and y are each in the range 0
to 255. The mask is set to 255.255.0.0 to provide a ~65000 entry address space.
The Dante Controller host must also have a Link Local address to communicate with
the card over the unit's AOIP port. Connect the AOIP port directly to a host (e.g.
laptop) running the Dante Controller, where the host address is preconfigured to an
iAM-SUM
