Speed Output Pulse
This output is for devices that can’t accept a RS-232 serial input.
It provides a 0-5 volt square wave output which can be fed into a digital
input on any MoTeC product. The frequency output calibration in
different speed units is:
94 Hz per 1 m/s
940 Hz per 36 km/h
1933 Hz per 46 mph
1.0638 cm per pulse
Speed Ready Output
The speed ready output pin is pulled high to 5v when the speed
signal is good, and low to 0v when there is not enough data for accurate
speed information. The speed output pulse incorporates this speed
ready signal to prevent the speed output from floating around to
erroneous values when the vehicle is stopped.
Variable Voltage Option
You can choose at the time of order to replace the speed output
pulse with a variable voltage output. The speed range should be
specified when ordering.
