This will be my last try in getting some sense to this :p
I understand that the NPN and the negative from the sensors are the right cables or signals to use on the com ports.
And I do get a signal and it does start the watches ( I use 2 watches for my set-up) but from there I´m stuck.
I need to have one sensor for the start, one for 50 meter and last one for 100 meter (stop).
So my question is. How do I wire this correctly?
All help is appreciated
