If you are trying to setup a Remote Device Access (RDA) in MAX there are several links on National Instruments web site that are very help full.

If you are trying to configure one of the older SCXI-1200 modules I would suggest referring to the user manual that is also available on the web at http://www.ni.com/pdf/manuals/320673c.pdf.
I hope this helps out.
