**Default Identifiers. The identifier values can be changed using the configuration software.
- The number of satellites used in the navigation solution.
- 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).
- Position, Latitude * 100,000 (311924579 = 51 Degrees, 59.24579 Minutes North). This is a true 32 bit signed integer, North being positive.
- Position, Longitude * 100,000 (11882246 = 0 Degrees, 58.82246 Minutes West). This is a true 32 bit signed integer, West being positive.
- Ground speed, 0.01 kts per bit.
- 2-D heading, 0.01° per bit.
- Altitude above mean sea level based on the WGS 84 model of the earth, 0.01 m per bit, signed.
- Vertical Velocity, 0.01 m/s per bit, signed.
- The percentage of free space available on the media.
- First status flags (see table below).
- Second status flags (see table below).
- Longitudinal Acceleration, 0.01 g per bit, signed.
- Lateral Acceleration, 0.01 g per bit, signed.
- Distance travelled since VBOX reset, 0.01 m per bit.
- Lap time from the OLED in milliseconds.
Note: This may lag behind the lap timing value sent in the 0x7E1 frame. - The delta-t value from the OLED in milliseconds.
- The lap timing session index.
- The lap number during this session.
- The lap number since start-up.
- The last lap time in milliseconds.
- 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).
- Lap status flags (see table below).
- Identifier of the most recently crossed lap timing gate.
- Identifier of the gate which started the lap or run.
- Video file primary number is the number which matches the .vbo file number.
- Video file fragment number is the number of video files since logging started.
- Video time is the number of milliseconds since the video file started.
- DM8148 temperature in °C.
- Set to 1 when logging, otherwise 0.
- HD2 input power voltage.
- Free space on the device being logged to in kB.
