Model 5202
Dante to Phones and Line Output Interface
Using the Dante Controller software ap-
plication the Model 5202’s IP address and
related network parameters can be set for
a fixed (“static”) configuration. While this is
more involved than letting DHCP or link-
local “do their thing,” if fixed addressing is
necessary then that capability is available.
But in this case it’s highly recommended
that each unit be physically marked, e.g.,
directly using a permanent marker or “con-
sole tape,” with its specific IP address. If
knowledge of a Model 5202’s IP address
has been misplaced there is no reset but-
ton or other method to 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 Windows
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 personal computer con-
nected directly to the Model 5202. 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 5202 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 5202 does not have a USB inter-
face for firmware updating. This is because
of the Model 5202’s simple, well-defined
functionality and commensurate limited-
resource MCU.
It’s possible that updated versions of the
Model 5202’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 5202
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 5202’s application firmware file
along with a text description file. Contact
the factory for additional details.
