RS485
RS485 is a balanced serial interface for the transmission of digital data. The advantage of a balanced
signal is the greater immunity to noise. Point to point or multi-point behaviour of this serial interface is
software dependent and is out of the scope of this manual. Description of the connector’s pins is from
DTE to DCE. The RBS acts as a DCE.
