Odometer
The AITP accumulates the quantity of distance pulses received from the last reset.
It also accumulates the time elapsed from the last reset. Time tics elapsed are accumulated a rate of
4800 tics/sec.
If Wheel Code (number of pulses for each Km) is supplied, Speed calculation is performed.
TD bytes 1-4 pulses from last odometer reset
bytes 5-8 time tics (4800 Hz) from last odometer reset
bytes 9-10 average speed from last odometer reset (m/s)
bytes 11-12 current speed (last second, m/s)
It is also possible to program a Speed Trigger, that is a speed limit over which the message WX is
triggered:
WS bytes 1-2 wheel code
bytes 3-4 speed limit for trigger (m/s)
WX byte 1-2 overspeed started, value is speed limit that has been exceeded
WM byte 1-2 overspeed end, value is max speed during overspeed
