each direction. RXD+ and TXD+ should idle high (going low at start of data transmission).
RXD- and TXD- should idle low (going high at start of data transmission). If necessary,
RXD+/RXD- and TXD+/TXD- may be swapped to maintain correct signal levels.
2. A ground terminal connection is recommended but not required.
