The next picture (below) shows typical RS485/422 differential input
signals RS485/422 LO (upper signal) and RS485/422 HI (lower
signal) at baud rate 9600. The vertical scale is 2V/div for both signals.
The ground level for each signal is shown with a small arrow at the
right. At the left the signals are at rest.
