MV Report
MV Command (G-R)
Movement log for accident analysis and driving profile. Generates 200 records corresponding to 20 seconds of accelerometer behavior (10 seconds before and 10 after the command).
Sampling frequency: 50Hz. Each record is generated from 5 samples.

| Field | Description |
|---|---|
| HHMISS | RTC time (HHMMSS) — comes first in the frame |
| DDMOYY | RTC date (DDMMAA) — comes after the time |
| .mmm | Milliseconds |
Accelerometer data
| Axis | Max Peak | Min Peak | Instant sample |
|---|---|---|---|
| X | +XMAX | +XMIN | +XCUR |
| Y | +YMAX | +YMIN | +YCUR |
| Z | +ZMAX | +ZMIN | +ZCUR |
The third value of each axis is not an average: it is the accelerometer’s instant sample at the time of the record. All three values share the same signed format (%+05d); there is no * prefix in the actual frame.
Additional fields
| Field | Description |
|---|---|
| RR | Heading, 2 hexadecimal digits |
| VVV | Speed (km/h), 3 decimal digits |
| III | Digital inputs status, 3 decimal digits |
| EE | Event number (hex, 00-FF) |
