Yamaha DTXpress/DTXplorer/DTXtreme

Hi, I wanted convert my drum set into an ekit so I put triggers on 
everything and bought a dtxpress module.  I didnt get a manual with 
the module and I am too dumb to figure out how to get the module to 
register the triggers.  Do I need a manual or is it something simple 
that I just dont know?  Please help me!!!!
