INTERCOM BELTPACK
6. At this time the Model 370A 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 re-
move the USB flash drive.
7. Confirm that the desired application
firmware version has been correctly
saved. This can be done by pressing
and holding the call button, applying
PoE power to the Model 370A, and
then “reading” the application firmware
version number by first observing the
channel 1 talk button’s LED and then
observing the channel 2 talk button’s
LED. Alternately, the STcontroller
software application can be used to
identify the application firmware ver-
sion number. Whatever method you
use, ensure that the desired version
is present.
8. Once the update process has been
completed reverse the steps and
reattached the cover using the four
machine screws.
Note that upon power being applied to the
Model 370A if a connected USB flash drive
doesn’t have the correct file (M370A.bin)
in the root folder no harm will occur. If the
correct file is not present upon power up
the call button’s LED will flash on and off
rapidly for a few seconds to indicate this
error condition and then normal operation
using the unit’s existing application firm-
ware will begin.
Ultimo Firmware Update
As previously discussed in this guide,
the Model 370A implements Dante con-
nectivity using the 2-input/2-output Ultimo
integrated circuit from Audinate. The
Dante Controller software application can
be used to determine the version of the
firmware (embedded software) that resides
in the Ultimo “chip.” The STcontroller
software application can also be used
to identify the Ultimo’s firmware version.
(Use the Version selection under the
Device tab.) The Ultimo firmware can
be updated by way of the Model 370A’s
Ethernet connection. The latest Ultimo firm-
ware file is available on the Studio Technol-
ogies website. The Dante Firmware Update
Manager (FUM) application program can
be used to install the Ultimo firmware. The
Dante Controller software application also
includes an automated method of updating
Ultimo firmware. It offers a much simpler
method of keeping the Ultimo firmware
current.
Model 370A versus Model 370
Some users may be interested in the dif-
ferences between the original Model 370
Intercom Beltpack and the newer Model
370A that is described in this guide. A
comparison chart is available on the
Studio Technologies website. In addition,
the following text provides a summary of
the changes:
• All configuration selections for the
Model 370A are performed using the
STcontroller software application.
STcontroller also allows the version
numbers of the Model 370A’s applica-
tion firmware (embedded software)
and Ultimo firmware to be remotely
identified.
• Support for electret microphones was
added to the Model 370A. This involved
adding a 5 volt DC power source to the
microphone input circuitry. This power
source can be enabled or disabled as
required using STcontroller.
