LAN. Even two Dante-enabled devices that
are directly interconnected using an RJ45
patch cord will correctly acquire IP ad-
dresses and be able to communicate and
transport audio.
Using the Dante Controller software ap-
plication the Model 43D’s IP address and
related network parameters can be set for
a fixed (“static”) configuration. While this
is more involved than letting DHCP or link-
local “do their thing,” if fixed addressing is
necessary then that capability is available.
But in this case it’s highly recommended
that each unit be physically marked, e.g.,
directly using a permanent marker or “con-
sole tape,” with its specific IP address. If
knowledge of a Model 43D’s IP address
has been misplaced there is no reset but-
ton or other method to 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) networking command can
be used to “probe” devices on a network
for this information. For example, in Win-
dows OS the arp –a command can be
used to display a list of LAN information
that includes MAC addresses and cor-
responding IP addresses. The simplest
means of identifying an unknown IP ad-
dress is to create a “mini” LAN with a per-
sonal computer connected directly to the
Model 43D. Then by using the appropriate
ARP command the required “clues” can
be obtained.
For best Dante Audio-over-Ethernet per-
formance a network that supports VoIP
QoS capability is recommended. This can
typically 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
(www.audinate.com) for details on optimiz-
ing networks for Dante applications.
Application Firmware Version
Display
As part of the Model 43D’s power-up se-
quence the unit’s application firmware
version number is displayed. This is use-
ful when working with factory personnel
on application support and troubleshoot-
ing situations. The five output 2 channel 1
LEDs are used to display the major release
number with a range of 1 through 5. The
five LEDs associated with output 2 channel
2 are used to display the release sub-num-
ber which ranges from 1 through 5. Refer
to Figure 3 for a detailed view of the LEDs
and the corresponding application firmware
version numbering scheme.
Figure 3. Detail of front panel showing the
status LEDs that display the application
firmware version. In this example, the
application firmware version is 1.2.
