Rafelmor,
Have you contacted The MathWorks yet? They probably have the best information.
However, I did a quick search and found some information on The MathWorks' site. For Data Acquisition Toolbox examples: http://www.mathworks.com/access/helpdesk/help/toolbox/daq/daq_example_index.shtml.
For RTW information: http://www.mathworks.com/support/product/RT/.
Good luck with your application.
