Important Notes:
2. RS485 communication wires should be connected in a bus cascade instead
of a star form, to achieve a better shielding eect by reducing signal reec-
tion during communications.
3. Adjust the communication speed as needed. The signal quality vary depend-
ing on wiring conditions, and it maybe necessary to lower the baudrates.
4. The GND Signal may be omitted if and only if the GND potential dierence
is less than ±5V
