* Default Identifiers. The identifier values can be changed using the configuration software.
- If Satellites in view < 3 then only Identifier 0x301 transmitted and bytes 2 to 8 are set to 0x00.
- 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 (515924579 = 51 Degrees, 59.24579 Minutes North). Latitude highest bit indicates north/south hemisphere. 0=north, 1=south, Bit 7 in Status is also set.
- Position, Longitude * 100,000 (5882246 = 0 Degrees, 58.82246 Minutes West). Longitude highest bit indicates east/west of Greenwich meridian. 0=west,1=east. Bit 6 in Status is also set.
- Velocity, 0.01 kts per bit.
- Heading, 0.01° per bit.
- Altitude, 0.01 m per bit, signed.
- Vertical Velocity, 0.01 m/s per bit, signed.
- Status. 8 bit unsigned char. Bit 0=VBOX Lite, Bit 1=Open or Closed CAN Bus (1=open), 2=VBOX3.
- Status is an 8 bit unsigned char. Bit 0 is always set, Bit 3=brake test started, Bit 4 = Brake trigger active, Bit 5 = DGPS active.
- Distance, 0.000078125 m per bit, unsigned.
- Longitudinal Acceleration, 0.01 g per bit, signed.
- Lateral Acceleration, 0.01 g per bit, signed.
- Distance travelled in meters since VBOX reset.
- Time from Trigger event to Zero km/h.
- Velocity at brake trigger point in Knots.
