To install the application firmware file
follow these steps:
1. Remove power from the Model 45DC.
This will entail removing the Ethernet
connection if it is providing PoE power
and/or removing the external source of
12 volts DC if that is being used.
2. Ensure that nothing is present in the
USB port. Then again apply power to
the unit and “read” the currently load-
ed application firmware version dur-
ing the power-up sequence using the
interface B level meters. (Refer to the
Application Firmware Version Display
paragraph earlier in this section.) Note
this for later reference.
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-
Ethernet (PoE) associated with a con-
nected Ethernet signal or can be from
an external 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 pe-
riod the LED located below the USB
connector will flash slowly on and off
green. Once the entire loading process
is over, taking approximately 10 sec-
onds, the Model 45DC will restart using
the newly-loaded application firmware.
7. At this time the Model 45DC is func-
tioning with the newly-loaded applica-
tion firmware and the USB flash drive
can be removed. But to be conser-
vative, 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 de-
sired 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.
