Sorry, maybe I wan not able to say what I mean 
I meant the connection between the wire from the sensor , the two mating connectors and , at the end, the pinX that is connected to Arduino.
I was only able to verify (with a multimeter) that the wire from mating connector to the pinX were ok with the exception of one... I crimped it and now it works with the multimeter...but It doesn't still output any data..
Can you post a picture of your gig?
yes - thx
so you carefully tested your cable?
Yes. I took for granted that black cable from sensor to black connector works because I can't open the sensor.
I tested the cable from the with mating connector to the pins I crimped and it works.
If the cable came with the sensor then it’s likely suited
If you used their code, their cable and their sensor and it does not work then you might have a faulty unit
I agree with you. I only have to test to short connect Rx and gnd of the sensor. They told me that in this way a manual trigger is sent to the sensor and it has to start to send measurement using tx. I hope I will do it one of this evenings. Thank you for all your answers, I will update the post as soon as I can.
Thought you had tried that before… I provided code for that… you said it did not work
I tried the "SW triggering" with your code. Now I mean the "HW triggering" connecting rx and gnd. I attach the instructions of the seller
that's what I suggested in post 23 (connecting to 5V instead of GND as SoftwareSerial is not doing well under high load, I went for the 2Hz version instead of 10Hz)
In post 29 you said it was not working
@J-M-L Sorry, probably I misunderstood your post. I got some confusion.
Your code works if I manually short-circuit RX and GND. I discovered it only now because, considering post #45 by @stitech, I replaced pin 7 with pin 10.
I thank you very much to both of you.
Now it works with the manual "HW trigger". So, why it doesn't work with the "SW trigger"?
I used code from the seller, pin 10 for RX and pin 11 for TX and now it works!
Now, I would like to understand why the other code posted above didn't work. I will test it tomorrow evening... thank you to all for your time!
May be your model does not support triggering
I tried the "SW triggering" with the code provided by the seller and it works if I modify the pins as I did with the "HW triggering"
progress !!
seems you are all set for your code then
Yes, thank you very much! I am not sure which post I have to click for the Solution. Can I click multiple posts? At least two
nope just one. it does not matter much which one you pick, what matters is that it will show the topic as "solved"
