MODEL 209
TALENT CONSOLE
using a permanent marker or “console tape,” with its
specific static IP address. If knowledge of a Model
209’s IP address has been misplaced there is no
reset button or other method to easily restore the unit
to a default IP setting.
In the unfortunate event that a device’s IP address
is “lost,” the Address Resolution Protocol (ARP) net
-
working command can be used to “probe” devices
on a network for this information. For example, in
Windows OS the arp –a command can be used to
display a list of LAN information that includes MAC
addresses and corresponding IP addresses. The
simplest means of identifying an unknown IP address
is to create a “mini” LAN with a small PoE-enabled
Ethernet switch connecting a personal computer to
the Model 209. Then by using the appropriate ARP
command the required “clues” can be obtained.
Optimizing Network Performance
For best Dante audio-over-Ethernet performance a
network that supports VoIP QoS capability is recom-
mended. In applications that utilize multicast Ethernet
traffic enabling IGMP snooping can be valuable.
These protocols can be implemented on virtually all
contemporary managed Ethernet switches. There
are even specialized switches that are optimized
for entertainment-associated applications. Refer to
the Audinate website (audinate.com) for details on
optimizing networks for Dante applications.
Application Firmware Version
Display
A selection in the STcontroller software application
allows the Model 209’s application firmware version
to be identified. This can be useful when working
with factory personnel on application support and
troubleshooting. To identify the firmware version, be
-
gin by connecting the Model 209 unit to the network
(via Ethernet with PoE) and wait until the unit starts
to function. Then, after starting STcontroller, review
the list of identified devices and select the specific
Model 209 for which you want to determine its ap-
plication firmware version. Then select Version
and
Information under the Device tab. A page will then
display that will provide lots of useful information. This
includes the application firmware version and well as
details on the Dante interface firmware.

Technical Notes
IP Address Assignment
By default, the Model 209’s Ethernet interface will
attempt to automatically obtain an IP address and
associated settings using DHCP (Dynamic Host
Configuration Protocol). If a DHCP server is not de-
tected an IP address will automatically be assigned
using the link-local protocol. This protocol is known
in the Microsoft® world as Automatic Private IP Ad-
dressing (APIPA). It is also sometimes referred to as
auto-IP (PIPPA). Link-local will randomly assign a
unique IP address in the IPv4 range of 169.254.0.1 to
169.254.255.254. In this way multiple Dante-enabled
devices can be connected together and automatically
function, whether or not a DHCP server is active on
the LAN. Even two Dante-enabled devices that are
directly inter-connected using an RJ45 patch cord will,
in most cases, correctly acquire IP addresses and be
able to communicate with each other.
An exception does arise when trying to directly inter
-
connect two Dante-enabled devices that use Ultimo
integrated circuits to implement Dante. The Model
209 uses the Ultimo “chip” and, as such, a direct
one-to-one interconnection between it and another
Ultimo-based product would not be supported. An
Ethernet switch linking these units would be required
to successfully interconnect the two Ultimo-based de-
vices. The technical reason that a switch is required
relates to the need for a slight latency (delay) in the
data flow; an Ethernet switch will provide this. This
wouldn’t typically prove to be an issue as the Model
209 uses power-over-Ethernet (PoE) to provide its
operating power. As such, in most cases a PoE-en-
abled Ethernet switch would be utilized to support
Model 209 units.
Using the Dante Controller software application,
the Model 209’s IP address and related network
parameters can be set for a manual (fixed or static)
configuration. While this is a more involved process
than simply letting DHCP or link-local “do their thing,”
if fixed addressing is necessary then this capability is
available. But in this case, it’s highly recommended
that every unit be physically marked, e.g., directly
