Chapter 5 Software Maintenance
Note:
z
The configuration files for system boot can be type M, B and default configuration
file of type N, but not non-default configuration file of type N (i.e. neither M nor B).
z
You can modify the file name of a configuration file in CF card using the command
after it boots. You cannot modify the type of the default configuration file, but you
can modify the file type of type M/B and N configuration files in the BootROM menu
or using commands after the application program boots.
You can store them in Flash memory, but only one for each. For example, if an M+B file
exists, it is impossible to have another M or B file. If you change the file type of another
file to B, the M+B file becomes a type M file.
Caution:
z
The file name cannot be longer than 64 characters (including drive letter and a
string terminator. If the drive letter is “CF:/”, the file name can be at most [ 64-1-4 ] =
59 characters in length; or, errors will occur in file operation. Typically, the file name
is recommended to be not more than 16 characters.
z
The extension ASCII characters (ASCII>=128) and invisible characters (ASCII<33)
cannot be included in the file name.

The following characters cannot be included in the file name: ”, ‘, ?, \, space, *, |, <,
/, :, >, ~.

The character “.” can be included in the file name, but cannot be the first or last
