2.12.1 RS-422 A and B signal definition
According to the following standard the signal state definitions are:
•
IEC 61162-1. The idle, marking, logical 1, OFF or stop bit states are defined by a
negative voltage on line A with respect to line B. The active, spacing, logical 0, ON
or start bit states are defined by a positive voltage on line A with respect to line B. It
should be noted that the above A with respect to B levels are inverted from the
voltage input/output requirements of standard UARTs and that many line drivers and
receivers provide a logic inversion.
2.12.2 Pin layout
2.12.2.1 COM 1 and 2
