We plan to use Leo Rover to collect sidewalk slope data.
The slope data is collected at a digital level [https://www.johnsonlevel.com/files/manuals/40-6250%20English%20Manual.pdf]
The digital level read slope. However, the digital level does not store data.
Thus, we want to transfer the slope data from the digital level to Raspberry Pi and store them as we collect them.
Since the digital level provides RS232 COM port, we use COM port to UART adapter (Adapter
Then, connect the UART port to Pi to get the data from the digital level.
After I connect the UART to hSen3, it seems like the port is open. However, I cannot read the data.
Thus, I tried with GPS module on hSen3, it works. I get the data.
However, it does not work with the digital level.
I checked the UART adapter on another Raspberry Pi and it worked.
Could you please help me with this?
Thank you very much!
