2.7 DIP SW Configuration

SW1-2 & 1

4W 4-wire (RS-485/422 driver receiver separated) 2W 2-wire (RS-485/422 driver receiver connected)

[2W] setting activates the internal connection between driver and re- ceiver in RS-485/422 interface. It simplifies the installation of the con- verter in a 2-wire bus. RS-422 usually uses 2-wire topology only. RS-485 supports both 2-wire and 4-wire topology.
