RS485 implementation is limited to half-duplex communication. So only Tx+, Tx- and ground reference
signals are necessary.
Depending on the RS485 network, an impedance adaptation may be required.
For farthest terminal, a 120-Ohms resistor termination may be added outside the terminal between TX+
and TX-.
