ANNOUNCER’S CONSOLE
Optimizing Network
Performance
For best Dante audio-over-Ethernet per-
formance a network that supports VoIP
QoS (voice-over-internet-protocol quality of
service) 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
There are two ways in which the version
number of the Model 205’s application firm-
ware (embedded software) can be identi-
fied. One requires only the Model 205 unit
and involves a button-press sequence per-
formed upon power up. The other method
utilizes the Model 205 and the STcontroller
software application. Either method may
prove to be useful when working with fac-
tory personnel on application support and
troubleshooting.
As part of the Model 205’s power-up se-
quence the unit’s application firmware can
be directly displayed. Before connecting
the PoE-enabled Ethernet cable, press and
hold the talkback 2 button. Then connect
the Ethernet cable. Upon application of PoE
power the Model 205 will not go through
its normal power-up sequence but instead
will display the firmware version. The green
LED associated with the main button will
“flash” to display the major version number.
Then the red LED associated with talkback
1 will “flash” to display the minor version
number. The LEDs will then remain off until
the talkback 2 button is released. Once
the talkback 2 button is released normal
operation will then take place. As an ex-
ample of what would be a typical firmware
display, if the main button’s LED “flashes”
green once followed by the talkback 1
button’s LED “flashing” red twice it would
indicate that application firmware version
1.2 is present in the Model 205.
A selection in the STcontroller software
application allows the Model 205’s ap-
plication firmware version to be identified.
Connect the Model 205 unit to the network
and let it connect and start to function.
Then, after starting STcontroller, review
the list of identified devices and select the
specific Model 205 from which you want to
determine its application firmware version.
Then select Version 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.
Application Firmware Update
Procedure
It’s possible that updated versions of the
application firmware (embedded software)
that is utilized by the Model 205’s proces-
sor (microcontroller or MCU) integrated
circuit will be released to add features or
correct issues. Refer to the Studio Tech-
nologies website for the latest application
firmware file. The unit has the ability to
load a revised file into the MCU’s non-
volatile memory by way of a USB inter-
face. The Model 205 implements a USB
host function that directly supports connec-
tion of a USB flash drive. The Model 205’s
MCU updates its firmware using a file
named m205.bin.
The update process begins by preparing
a USB flash drive. The flash drive doesn’t
have to be empty (blank) but must be in
