circuit from Audinate. The Dante Controller
software application can be used to deter-
mine the version of the firmware (embedded
software) that resides in the Ultimo “chip.”
The STcontroller software application can
also be used to identify Ultimo’s firmware
version. (Use the Version selection under
the Device tab.) The Ultimo firmware can be
updated by way of the Model 373A’s Ether-
net connection. The latest Ultimo firmware
file is available on the Studio Technolo-
gies’ website. The Dante Firmware Update
Manager (FUM) application program has
traditionally been used to install the Ultimo
firmware. The Dante Controller software ap-
plication also includes an automated method
of updating Ultimo firmware. Both applica-
tions are available, free of charge, on the
Audinate website (www.audiante.com).
Restoring Factory Defaults
A command in the STcontroller software ap-
plication allows the Model 373A’s configura-
tion to be reset to the factory default values.
From STcontroller select the Model 373A for
which you want to restore its defaults. Select
the Device tab and then select the Factory
Defaults feature. Then click on the OK box.
Refer to Appendix A for a list of the Model
373A’s factory default values.
will flash slowly in alternate colors. Once
the entire process is over, taking approxi-
mately 10 seconds, the Model 373A will
restart using the newly saved application
firmware.
6. At this time the Model 373A is operat-
ing under the newly saved application
firmware and the USB flash drive can be
removed. But to be conservative, remove
PoE power first and then remove the USB
flash drive.
7. Confirm that the desired application firm-
ware version has been correctly saved.
This can be done by pressing and holding
the talk pushbutton, applying PoE power
to the Model 373A, and then “reading”
the application firmware version number
by observing the talk pushbutton’s LED.
Alternately, the STcontroller software ap-
plication can be used to identify the appli-
cation firmware version number. Whatever
method you use, ensure that the desired
version is present.
8. Once the update process has been com-
pleted reverse the steps and reattached
the cover using the four machine screws.
Note that upon power being applied to the
Model 373A, if a connected USB flash drive
doesn’t have the correct file (M373A.bin) in
the root folder no harm will occur. If the cor-
rect file is not present upon power up the talk
pushbutton’s LED will flash rapidly, alternat-
ing green and orange, for a few seconds to
indicate this error condition after which nor-
mal operation using the unit’s existing appli-
cation firmware will begin.
Ultimo Firmware Update
As previously discussed in this guide, the
Model 373A implements Dante connectivity
using the 2-input/2-output Ultimo integrated
