The RS485 2 wire without echo mode is designed for astandard RS485 connection.

• The RS485 line must be polarised and there must bea polarisation resistor at both ends of the bus.

• The termination resistor limits reflections on thetransmission line when there is a large distancebetween equipment. The termination must be fittedto both ends of the bus.
