2. Locate the USB receptacle on the
Model 5401A’s back panel. It is labeled
Firmware Update. Directly adjacent to
the USB receptacle is a small hole that
provides visual access to a green LED
indicator.
3. Insert the prepared USB flash drive into
the USB receptacle.
4. Apply power to the Model 5401A. Power
can be provided by connecting AC mains
or a source of nominal 12 volts DC.
5. After a few seconds the Model 5401A
will run a “boot loader” program that will
automatically load and save the new
firmware file(s) that are present on the
USB flash drive. The update process can
range from approximately 10 seconds to
approximately 60 seconds, depending
on which of the three files are going to
be updated. While files are being loaded
the green LED, located adjacent to the
USB receptacle, will flash slowly. Once
the entire loading process has complet-
ed the Model 5401A will reboot (restart)
using the newly saved firmware.
6. At this time the Model 5401A is function-
ing with the newly loaded firmware and
the USB flash drive can be removed.
7. It’s a good idea to confirm that the de-
sired Model 5401A’s Main MCU, Main
FPGA, and Sync FPGA firmware ver-
sions are loaded and operating as
expected. There are two methods for
observing the Model 5401A’s firmware
version numbers. The most direct is to
use the front-panel display. Alternately,
the System webpage from the manage-
ment webpages can be utilized.
Note that no harm will occur if power is ap-
plied to the Model 5401A that has a USB
flash drive connected that doesn’t have rel-
evant files in its root folder. Upon power up
the green LED, located adjacent to the USB
receptacle, will flash on and off rapidly for a
few seconds to indicate that a valid file has
not been found. After this warning, normal
operation using the unit’s existing firmware
will begin.
Dante Firmware Update
As previously discussed in this guide, the
Model 5401A implements Dante connec-
tivity using the Brooklyn II module from
Audinate. The Dante Controller software ap-
plication can be used to determine the ver-
sion of the firmware (embedded software)
that resides in the Brooklyn II module. The
System webpage provided by the Model
5401A’s management web server can also
be used to identify the firmware version.
The firmware (embedded software) residing
in the Brooklyn II module can be updated
using the Model 5401A’s Dante primary Eth-
ernet port. Performing the update process
is easily accomplished using an automated
method called Dante Updater that’s includ-
ed as part of the Dante Controller software
application. The Dante Controller applica-
tion is available, free of charge, from the
Audinate website (audinate.com).
The latest Model 5401A firmware file, with
an extension of .dnt, is available on the Stu-
dio Technologies’ website as well being part
of Audinate’s product library database. The
latter allows the Dante Updater software ap-
plication that is included with Dante Control-
ler to automatically query and, if required,
update the Model 5401A’s Dante interface.
Restoring Model 5401A’s
Default Configuration Values
A command in the System Information
webpage provided by the Model 5401A’s
management web server allows most of the
configuration settings to be restored to their
default configuration values. This can be
useful but must be used with caution. Any
customization made to the Model 5401A’s
