If ''Crash Detection'' is enabled, it monitors acceleration on each axis which helps detecting an accident. ''Threshold'' and ''Duration'' values are set depending on the impact that is required to be detected. {{{model|FMB1YX}}} can detect events ranging between a slight tapping on the device (Threshold = 100 mG, Duration = 1 ms) and a severe accident (Threshold = 4000 mG, Duration = 5 ms).<br/>If ''Crash Trace'' is disabled a crash detection event will be generated (included into the sent record) only when scenario starts and finishes.<br/>

If ''Crash Trace'' is enabled {{{model|FMB1YX}}} will collect acceleration data every 40 miliseconds. Buffer is big enough to hold data for 5 seconds and in the event of Crash records will be generated from this buffer, following from these conditions:

If ''Crash Trace'' is disabled a crash detection event will be generated (included into the sent record) only when scenario starts and finishes.<br/>

* Every second that acceleration changed more than 50mG, the data will be collected and records will be generated for a duration of 5 seconds after the event.

 

* Every generated record will have accelerometer X Y Z values included.

If ''Crash Trace'' is enabled, {{{model|FMB1YX}}} will collect acceleration data every time period defined by ''Trace ODR (Hz)'' parameter and IO data every second. Buffer is big enough to hold data for 5 seconds before crash event and 5 seconds after. On Crash Event detection, records will be generated from this buffer, following these conditions:<br/>

* Each record will have accurate timestamps in milliseconds.

* Every second

* Acceleration changed more then >50mG <br/>

* Every second with IO's, configured in I/O settings, under "Event only" parameter

* With frequency defined by ''Trace ODR (Hz)'' parameter <br/>

Each record will have accurate timestamps in milliseconds. <br/>
