Using lap marker files with the DASH2
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.
