Model 5204
Dual Line Input to Dante Interface
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 5204. 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.
Updating Main Application
Firmware
The Model 5204 uses a Freescale HCS-
08-series microcontroller (MCU) integrated
circuit to run its main application firmware
(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 header connector located on the
unit’s motherboard. This firmware program-
ming is done at the factory at the time of
manufacture using a Cyclone Pro or Cy-
clone Universal stand-alone programmer
unit from P&E Micro (www.pemicro.com).
There is no provision for updates of the ap-
plication firmware to easily be performed
in the field. Unlike some of the other Studio
Technologies’ Dante-enabled products, the
Model 5204 does not have a USB inter-
face for firmware updating. This is because
of the Model 5204’s simple, well-defined
functionality and commensurate limited-
resource MCU.
It’s possible that updated versions of the
Model 5204’s application firmware will be
released. This could be due to software
bug fixes or feature improvements. It’s
expected that in most cases Model 5204
units will 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 refer-
ence the Studio Technologies’ website
will make available the latest version of
the Model 5204’s application firmware file
along with a text description file. Contact
the factory for additional details.
Ultimo Firmware Update
As previously discussed in this guide, the
Model 5204 implements Dante connectivity
using the 2-input/2-output Ultimo integrat
-
ed circuit from Audinate. The Dante Con-
troller software application can be used
to determine the version of the firmware
(embedded software) residing in the Ultimo
“chip. This firmware can be updated by
way of the Model 5204’s Ethernet connec-
tion. The latest Dante firmware file is avail-
able on the Studio Technologies website.
The Dante Firmware Update Manager
application is used to install the firmware.
This program is also available for down-
load on the Studio Technologies website.
