Yamaha DTXpress/DTXplorer/DTXtreme

I purchased a concertcast pad from pintech at another store today,
and cannot seem to get it to trigger off the rim on either the sw. on the
snare or on input 9/10. So I cannot say they are in fact compatible. It appeared to work
at the place where I first purchased the dtxpress, so I may have a bad pad/trigger. I'll have 
to investigate this further. Sorry for the confusion. I guess it still a ????
regarding Pintechs(dual zone) on the dtxpress.
