Optimizing Network
Performance
For best Dante audio-over-Ethernet perfor-
mance a network that supports VoIP QoS
capability is recommended. This can typi-
cally be implemented on virtually all con-
temporary 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 362’s power-up
sequence the unit’s application firmware
(embedded software) version number will
automatically be displayed. This is useful
when working with factory personnel on
application support and troubleshooting.
Upon application of PoE power the Model
362’s green power LED, located on the
unit’s top panel, will light in a simple
“code” to indicate the version number. It
will first “flash” the major version number,
briefly pause, then flash the minor version
number. Once the version number has dis-
played a slight pause will take place and
then the power LED will light sold green.
As an example of what would be a typical
firmware display, if the green power LED
“flashes” once, turns off momentarily, then
again “flashes” once it would indicate that
application firmware version 1.1 is present
in the Model 362.
Updating the Application
Firmware
The Model 362 uses an NXP® Kinetis®-
series microcontroller (MCU or processor)
integrated circuit to run its application firm-
ware (embedded software). The firmware
is loaded into and stored in the MCU’s non-
volatile memory by way of a stand-alone
hardware programmer unit that interfaces
with a miniature header connector located
on the unit’s motherboard. This firmware
programming is done at the factory at the
time of manufacture using a Cyclone Uni-
versal, Cyclone Universal FX, or other com-
patible stand-alone programmer unit from
P&E Micro (www.pemicro.com). There is no
provision for easily field-updating the Model
362’s application firmware. Unlike some
of the other Studio Technologies’ Dante-
enabled products, the Model 362 does not
have a USB interface for firmware updating.
This capability was deemed unnecessary
and impractical due, in part, to the Model
362’s simple, well-defined functionality and
compact size.
It’s possible that updated versions of the
Model 362’s application firmware will be
released. This could be due to software
bug fixes or feature improvements. It’s ex-
pected that in most cases Model 362 units
would be returned to the factory should this
firmware need to be loaded. This would be
true unless a user, reseller, or distributor
has access to an appropriate stand-alone
programmer unit. For reference the Studio
Technologies’ website will make available
a listing of the latest version of the Model
362’s application firmware along with a
text description file. Contact the factory
for additional details.
