MODEL 371A
INTERCOM BELTPACK
would use two Model 371A units without
a PoE-enabled Ethernet switch being
present.
Using the Dante Controller software
application the Model 371A’s IP address
and related network parameters can be
manually set for a fixed (static) configura-
tion. While this is a more-involved process
than simply letting DHCP or link-local
automatically assign an address, if fixed
addressing is necessary then this capabil-
ity is available. But in this case it’s highly
recommended that each unit be physically
marked, e.g., directly using a permanent
marker or “console tape,” with its specific
static IP address. If knowledge of a Model
371A’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) 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
small PoE-enabled Ethernet switch con-
necting a personal computer to the Model
371A. Then by using the appropriate ARP
command the required “clues” can be
obtained.
Optimizing Network
Performance
For best Dante audio-over-Ethernet per-
formance a network that supports VoIP
Quality-of-service (QoS) capability is rec-
ommended. This can be implemented on
virtually all contemporary managed Ether-
net switches. There are even specialized
switches that are optimized for entertain-
ment-associated applications. Refer to the
Audinate website (www.audinate.com) for
details on optimizing networks for Dante
applications. Also, be certain to disable
Energy-Efficient Ethernet (EEE) support on
all Ethernet switch ports that are associ-
ated with Dante devices. Some implemen-
tations of EEE can incorrectly interpret
that a connected device is not present and
prevent proper Dante operation.
Application Firmware Version
Display
There are two ways in which the version
number of the Model 371A’s application
firmware (embedded software) can be
identified. One requires only the Model
371A unit and involves a button-press
sequence performed upon power up. The
other method utilizes the Model 371A and
the STcontroller software application. Ei-
ther method may prove to be useful when
working with factory personnel on applica-
tion support and troubleshooting.
As part of the Model 371A’s power-up
sequence the unit’s application firmware
(embedded software) version number
can be displayed. Before connecting the
PoE-enabled Ethernet cable, press and
hold the call button. Then connect the
Ethernet cable. Upon application of PoE
power the Model 371A will go through its
normal power-up sequences followed by
a display of the firmware version. The LED
associated with the channel 1 talk button
will “flash” to display the major version
number. Then the LED associated with
the channel 2 talk button will “flash” to
display the minor version number. Once
