HistoryCount,File,Project,Window,Command
This allows the user to change the number of entries for the history of files, projects, windows and
commands.
Hide/RestorePDM(PhotonDesktopManager)
Hide and restore PDM when M300 does play/stop or enter/exit (star M300 /exit M300).
When M300 runs it’s always best to have as much desktop space available for the project windows.
The PDM uses some space at the bottom of the display. This allows the user to hide the PDM if
desired.
ProjectFiles
Allow write permission to M300 project files.
While M300 is running, if the project is changed, the user will be asked to save the project on exit.
Assuming the user asks to save the project, if the user was ending any M300 file, such as fml.300,
that file would be overwritten.
To avoid confusion, the user should not change any project files while the M300 is running with the
editor. Having the editor open (like vedit) while M300 is running, has another problem. The M300
can setup function keys to execute command globally. This has the potential to interfere with the
vedit when the user is in vedit making changes.
ConfirmExit
This option when clicked will ask the user for extra confirmation before exiting the M300.
This is to avoid undesired termination of the M300 system, specially in aircraft environments where
it’s hard to operate the mouse/keyboard while in turbulence.
DeltaTimetocauseInitReset
When working with M300 data that has been acquired with time synchronization to another source
(usually IRIG-B), if the adjustment in time is forward, this is okay with the M300 Trigger frequency
values.
However, if the adjustment is backwards this will cause issues with Trigger frequency values around
the time the data was synchronized.
Having this variable allows use to correct for this and trigger on all the data as expected.
Depending on how big the adjustment was, you might use a 1 or 2 second value for this variable.
This option is only used for playback. The time is in seconds.
