Application Firmware Update
Procedure
The application firmware used for original
Model 44D units is compatible with that
used in the updated Model 44D units.
As such, as newer firmware versions are
released they can be directly loaded into
units of either type. The only difference is
the location of the USB interface connec-
tor. Original Model 44D units contained
a USB interface connector on their back
panel. A USB status LED is located ad-
jacent to this connector. The firmware
update procedure instructions provided
in this user guide for the updated units
apply to the original unit as well, with the
exception that the cover does not have
to be removed. The USB flash drive that
contains the desired M44D.bin file will be
inserted into the connector on the back
panel. So as it relates to loading applica-
tion firmware, original Model 44D units
offer a much simpler means to access the
USB interface connector.
