Yamaha DTXpress/DTXplorer/DTXtreme

hello all,
              i just bought a pintech hyperhat pedal from ebay,and 
can't seem to get it to work with my dtxepress module,i tried this 
using a stereo cable ,and nothing happened, i had hooked up my old 
pedal,and it worked fine,i had the pintech pedal tested and it works 
perfectly,just doesn't seem to want to work on my module,if anyone 
may know if this pedal is compatable with my module or not,i would 
really apreciate any info. that you can give me,thanks for your time
