MODEL 370A
INTERCOM BELTPACK
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
370A’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 in-
cludes MAC addresses and corresponding
IP addresses. The simplest means of identi-
fying an unknown IP address is to create
a “mini” LAN with a small PoE-enabled
Ethernet switch connecting a personal
computer to the Model 370A. 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 associated
with Dante devices. Some implementations
of EEE can incorrectly interpret that a con-
nected 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 370A’s application
firmware (embedded software) can be
identified. One requires only the Model
370A unit and involves a button-press
sequence performed upon power up. The
other method utilizes the Model 370A and
the STcontroller software application. Either
method may prove to be useful when work-
ing with factory personnel on application
support and troubleshooting.
As part of the Model 370A’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 Ether-
net cable. Upon application of PoE power
the Model 370A will go through its normal
power-up sequences followed by a display
of the firmware version. The LED associ-
ated 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 the version number
has been displayed the call button can be
released and normal operation will begin.
As an example of what would be a typical
application firmware display, if the channel
1 talk button “flashes” once followed by
the channel 2 talk button “flashing” two
times this would indicate that application
firmware version 1.2 was present in the
Model 370A.
A selection in the STcontroller software
application allows the Model 370A’s ap-
plication firmware version to be identified.
Connect the Model 370A unit to the net-
work and let it connect and start to func-
