Yamaha DTXpress/DTXplorer/DTXtreme

Greetings everyone,

I have a new-used Dtexpress II with my snare only firing the snare 
sound. The rims are not firing separate sounds. 

The first thing I did when I got the kit home was too reset the 
factory presets, still no sounds out of all three zones from my 
TP65s. Ohhh and it's plugged into input #2 with a stereo cord.

Am I missing something? Is there a setting I can go too to fix this 
or is this trigger toast?? 

Thanks in advance,
D~man.
