Receive
This function is designed for high resolution vehicle speed sensors and wheel speed
sensors. It expects a normally low input with a high state for the trigger. If the pulse length
is more than 0.1 metres the odometer input function should be used, if it is less than 0.1
metres the wheel speed sensor function should be used. Contact technical support via
