**Default Identifiers. The identifier values can be changed using the configuration software.

  1. The number of satellites used in the navigation solution.
  2. Time since midnight. This is a count of 10 ms intervals since midnight UTC. (5383690 = 53836.90 seconds since midnight or 14 hours, 57 minutes and 16.90 seconds).
  3. Position, Latitude * 100,000 (311924579 = 51 Degrees, 59.24579 Minutes North). This is a true 32 bit signed integer, North being positive.
  4. Position, Longitude * 100,000 (11882246 = 0 Degrees, 58.82246 Minutes West). This is a true 32 bit signed integer, West being positive.
  5. Ground speed, 0.01 kts per bit.
  6. 2-D heading, 0.01° per bit.
  7. Altitude above mean sea level based on the WGS 84 model of the earth, 0.01 m per bit, signed.
  8. Vertical Velocity, 0.01 m/s per bit, signed.
  9. The percentage of free space available on the media.
  10. First status flags (see table below).
  11. Second status flags (see table below).
  12. Longitudinal Acceleration, 0.01 g per bit, signed.
  13. Lateral Acceleration, 0.01 g per bit, signed.
  14. Distance travelled since VBOX reset, 0.01 m per bit.
  15. Lap time from the OLED in milliseconds.
    Note: This may lag behind the lap timing value sent in the 0x7E1 frame.
  16. The delta-t value from the OLED in milliseconds.
  17. The lap timing session index.
  18. The lap number during this session.
  19. The lap number since start-up.
  20. The last lap time in milliseconds.
  21. Single byte lap timing beacon; typically 0x00 but will be 0x01 for the first frame after starting a lap (i.e. crossing a start line).
  22. Lap status flags (see table below).
  23. Identifier of the most recently crossed lap timing gate.
  24. Identifier of the gate which started the lap or run.
  25. Video file primary number is the number which matches the .vbo file number.
  26. Video file fragment number is the number of video files since logging started.
  27. Video time is the number of milliseconds since the video file started.
  28. DM8148 temperature in °C.
  29. Set to 1 when logging, otherwise 0.
  30. HD2 input power voltage.
  31. Free space on the device being logged to in kB.
