This project uses an Arduino Mega to read a Modbus RTU feed through RS485. This example is based on a Huawei / CHINT DTSU666-H.

From my experience it is absolutely needed to have an Arduino Mega or equivalent (needs to have at least 2 serial ports), you won't be able to read the Modbus if Serial is also used by USB Serial ...
