1. RS-422 transmit and receive are balanced signals that require two lines plus a ground
in 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.
