3.1 DIP Shunt Settings

The V.35↔RS-422 Interface Converter has two jumper selectable configurations determined by DIP shunt settings located inside the unit on the printed circuit board. One configuration is for connecting RS-422 DTE to V.35 DCE. The second configuration is for connecting V.35 DTE to RS-422 DCE. See Figure 3-1 for more information on DIP Shunt settings.
