2-Series Integrated Dual Bus Control System
Appendix B: File System
The file system inside the 2-series control engine can be broken down into two parts.
The first part resides on the on-board flash memory and the second resides on the
external compact flash/microdrive card. This appendix briefly describes the structure
of the file system.
The files that reside in the internal flash conform to a flat directory structure. The
compact flash system contains a fully FAT32 compatible file system to allow the
same compact flash card to be used in a Windows environment. The table, shown
below, presents the structure of the overall file system.

CFx
The mounting point for the compact flash files,
where x is the number of the compact flash slot
(0 = on board slot, i.e., \CF0 refers to the on-
board slot)
Although the file system is case insensitive, the case is preserved to maintain file
checksums. The compact flash directory only appears when the compact flash is
inserted into the system. To reference files on the compact flash, prefix the “\CFx\”
to any fully qualified path from the Windows environment. For example, if the file in
Windows is “\MyDirectory\MySubdirectory\MyFile.ext”, the complete 2-series path
for a file on the first Compact Flash slot (onboard) is:
“\CF0\MyDirectory\MySubdirectory\MyFile.ext”
