Yamaha DTXpress/DTXplorer/DTXtreme

Wondering if anyone knows if the DTXpress brain can accept a dual zone Cy-5 HH cymbal.? I know the brain handles 3 zone snare- and 3 zone chokables (in the right imput)-
and the HH imput has full funcionallity for opn clsd splash etc--
BUT is the HH imput capable of detecting a dual zone cymbal as well.? If not~ can the brain be 'changed' to make it work somehow?
