In a typical RS-485 application, the host device requests data from
a slave module that listens for the response. The host transmits and
receives data on the same pair of wires. Software handles the flow
control; no other wires are needed. Pin assignments appear in the
table. Pins 1 and 4 share the Data- wire. Pins 2 and 3 share the
Data+ wire.
