    I am trying to control a RS-485 RTU device (Love 16C-3) using a Python script (pymodbus library) that runs on a Windows 10 PC. The hardware is connected to the computer using a USB-RS232 cable.

    In my initial test, the Python script is not able to read anything off the RS-485 device.

    What is the RS-485 pin out for the DB9 connector?
    Should a USB-RS485 cable be used instead?
