Application Firmware Version
Display
As part of the Model 5330’s power-up
sequence the two LED level meters associ-
ated with the monitor section, located on
the right side of the front panel, will indicate
the unit’s application firmware version num-
ber. Knowing the version number can be
useful when working with factory personnel
on application support and troubleshooting
situations. The eight LEDs associated with
the left meter are used to display the major
release number with a range of 1 through
8. The eight LEDs associated with the right
meter are used to display the release sub-
number which ranges from 0 (no LED lit)
through 8.
Application Firmware Update
Procedure
It’s possible that updated versions of the
application firmware (embedded software)
that runs the Model 5330’s microcontroller
(MCU or processor) integrated circuit will be
released to add features or correct issues.
Refer to the Studio Technologies’ website
for the latest application firmware file. The
unit has the ability to automatically load
revised files into the MCU’s non-volatile
memory by way of its USB interface. The
Model 5330 implements USB host function-
ality and provides access by way of a type
A receptacle on the back panel. A standard
USB flash drive is used to provide an up-
dated file that is named M5330.bin.

The update process begins by preparing
a USB flash drive. The flash drive doesn’t
have to be empty (blank) but must be in the
personal-computer-standard FAT32 format.
The new firmware file will be saved in the
root directory with a name of M5330.bin.
Studio Technologies will supply the ap-
plication firmware file inside a .zip archive
file. While the firmware file inside of the zip
file will adhere to the naming convention
required by the Model 5330, the name of
the zip file itself will include the file’s ver-
sion number. For example, a file named
M5330v1r3MCU.zip would indicate that
