bit 3 Geofence event

bit 4 Panic switch activated

bit 5 External input/output event

bit 6 Journey START

bit 7 Journey STOP

bit 8 Heading change

bit 9 Low battery

bit 10 External power event

bit 11 Idling start event

bit 12 Idling end event

bit 13 Idling ongoing

bit 14 Power ON or RESTART event

bit 15 Speed overthreshold

bit 16 Towing event (vehicle moving with IGN off)

bit 17 Unauthorised driver alarm (vehicle IGN on and unknown driver)

bit 18 Collision alarm (excessive G forces detected)

bit 19 Accel threshold maximum event (positive X axis)

bit 4 Reports to follow

bit 5 Stored/Live report (1 = stored, 0 = live)

bit 6 Immobiliser current state (1 = immobilsed, 0 = not immobilised)

bit 7 RS232 external device read error

bit 8 GPS jammer detected (0 = no jammer, 1 = jammer detected)
