Application Firmware Version
Display
As part of the Model 45DC’s power-up
sequence the unit’s application firmware
version number is displayed. This is use-
ful when working with factory personnel on
application support and troubleshooting
situations. The five To meter LEDs associ-
ated with interface B are used to display
the major release number with a range of 1
through 5. The five From meter LEDs asso-
ciated with interface B are used to display
the release sub-number which ranges from
1 through 5. Refer to Figure 4 for a detailed
view of the LEDs and the corresponding
application firmware version numbering
scheme. The Model 45DC’s initial applica-
tion firmware release is version 2.2 which is
represented by the second from the bottom
LED of each column being lit.
Application Firmware Update
Procedure
It’s possible that updated versions of the
application firmware (embedded software)
that runs the Model 45DC’s microcontroller
(MCU) 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 45DC
implements a USB host function that direct-
ly supports connection of a USB flash drive.
The Model 45DC’s MCU updates using a
file named M45DC.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. Save the new firmware file in the
root directory with a name of M45DC.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 45DC, the name of
the zip file itself will include the file’s ver-
sion number. For example, a file named
M45DCv2r2MCU.zip would indicate that
version 2.2 of the application firmware
( M45DC.bin) is contained within this zip
file. Two of the LED meters should be used
to confirm that the correct application
firmware version has been successfully
installed.

status LEDs that display the application
firmware version. In this example, the
application firmware version is 2.2.
