The AK-SM can read & write to USB flash based drives. Upon
insertion (or via main menu option 7), the USB menu window will
be shown (for DIN units read following section). A typical
example of the resulting pop up screen can be seen below, with
descriptions for each option. The menu reflects supported files
located on the USB memory stick, and may vary from the
example below. Ensure relevant software files are located in the
USB root directory. When updating your AK-SM it is recom-
mended to first update the ‘Bootloader’ (if specified), followed by
the Master Application Image (MAI). The MAI contains AK-SM
firmware, EDF and Web files needed.

Remotely Upgrading you AK-SM unit - what is the FAI file
Your AK-SM has the ability to be upgraded via a remote connec-
tion (RMT). Upgrading via remote offers several advantages, the
obvious one being time saving. However, this is increased risk
when preforming remote upgrades (i.e. quality of connectivity,
power..). Software version 03_051 (and above) comes with an
additional extension, FAI (Factory Application Image). The FAI
software file contains special code designed to support remote
software upgrades. The FAI file provides a ‘fall back’ state, if at
any time a later remote upgrade fails or gets corrupted. Rather
than leave a unit in a unstable state in the event of a corrupted
remote upgrade, the factory image ensures you can always make
contact to re-install code again. In addition, the FAI contains the
MAI, which also contains all relevant web and EDF files. Via the
Info screen, check if your AK-SM unit has a Factory Application
installed. For future remote upgrades it is recommended that the
FAI is installed if it is not already present in your system. The AK-
SM can run without the FAI, with firmware updates being done
via the MAI file.
Under the Info->Information tab, check to see if a Factory Application
is installed (FAI).
If you intend to perform remote software updates, Danfoss recom-
mends the loading of the FAI file.

Recommended method for upgrading your AK-SM - Boot-
loader
The AK-SM bootloader file is a critical file that manages system
boot up sequence and system management. The Bootloader can
not
be loaded remotely. Updating the bootloader can be done
in application mode (normal AK-SM operation) or when placed in
bootloder mode. The following description of how to upgrade
your Bootloder version is via normal AK-SM operation mode.
