Hello


I have no understanding of equipment. 


I bought the urm14-rs485 product.


I am trying to communicate with the PC by connecting USB to 485.

 

There is no response even when communicating using modbus rtu.

 

When I looked at the wiki, it connected to Arduino and ran a setup loop.


I would like to know if the product cannot be used without an Arduino board.

 

Thank you for reading. I look forward to your reply.

This sensor could work without the Arduino board.

But please note that you need to power it with 7-15V for it to work properly.And the RS485 connection should be A-A, B-B.Also, please share your data frame with us so we can see if you are missing anything
