LapTimingOnDASH3 / AddingMarkersFromTheAnalysisSoftware

Adding track markers from the Analysis Software

Adding track markers can be done using the track marker files. To generate a track marker file from raw data, please refer to the section on Adding Track Markers in the Analysis Software documentation or Race Technology On-line Help System.

Lap files must have the following naming conventions.

  • The file names MUST be in 8.3 format, meaning that it must have no more than 8 characters before the decimal point and 3 characters after the decimal point.
  • The file extension MUST be ".LAP"

If the files are not named in this way the data logger will not recognize them.

The resulting lap file should be saved to compact flash card for transfer to the data logger. The lap file must be placed in the root directory of the Compact Flash card. It is advisable not to have multiple lap files with similar marker locations in this directory to avoid the possibility of the data logger selecting the wrong lap marker file if multiple lap files are present.

Using lap marker files with the DASH3

The data logger stores the lap markers in a lap file in the root directory of the compact flash card. At the start of a run, the data logger will check its current position against the reference positions in any lap files on the memory card. As such, you can have 10 different lap files on the card, and so long as they were not started within about 15km of each other, the data logger will pick up the correct one for the current location. For this reason, it is very important that the data logger has a GPS lock at the start of the run; otherwise it will just pick up the first file found. If there are no files on the compact flash card, then it will write to the file MARKER01.LAP, if MARKER01.LAP already exists, it will go to MARKER02.LAP, and so on.
