(Output 1 or 2: Sync index)
The scanner outputs a signal depending on the position of the scanner head. This pulse
is output at the time of the first measuring point (-45°) and it corresponds to the start-of-
scan time stamp in the measurement data. The length of the pulse is approx. 5 ms.
Important
Program the vehicle computer so that it responds to the falling edge of the output pulse.
