3. Remove power from the Model 45DC.
4. Insert the prepared USB flash drive into
the Model 45DC’s USB port, located on
the back panel of the unit.
5. Apply power to the Model 45DC. Power
can be provided by Power-over-Ether-
net (PoE) associated with a connected
Ethernet signal or can be from an exter-
nal 12 volt DC source.
6. The Model 45DC will run a “boot
loader” program that will immediately
load the new application firmware file
(m45DC.bin). This process takes only
a few seconds. During this time period
the LED located below the USB con-
nector will flash slowly on and off green.
Once the entire loading process is over,
taking approximately 10 seconds, the
Model 45DC will restart using the newly-
loaded application firmware.
7. At this time the Model 45DC is function-
ing with the newly-loaded application
firmware and the USB flash drive can
be removed. But to be conservative,
remove power first and then remove
the USB flash drive.
8. Apply power to the Model 45DC and
“read” the application firmware version
number by observing the channel B
level meters. Ensure that this is the
desired version and that it’s different
from that noted in step 2.
Note that upon power being applied to the
Model 45DC if the USB flash drive doesn’t
have the correct file (m45DC.bin) in the
root folder no harm will occur. Upon power
up the USB LED will flash on and off rapidly
for a few seconds to indicate this condition
and then normal operation using the unit’s
existing application firmware will begin.
Ultimo Firmware Update
As previously discussed in this guide, the
Model 45DC implements Dante connectiv-
ity using the Ultimo integrated circuit from
Audinate. This 2-input/2-output device can
be updated by way of the Model 45DC’s
Ethernet connection. The latest Dante
firmware file is available on the Studio
Technologies website. The Dante Firm-
ware Update Manager application is used
to install the firmware. This program is
also available for download on the Studio
Technologies website.
