RS485 Connection
PC Connection
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
Do not use
