HPD15 Handsonic Pics???

[lateralus778]

I'm looking for a hi quality picture of the back panel of an HPD15 but can't seem to find one.
at the website, there are only top pics and all they say is:

"MIDI In/Out plus dual-trigger input and hi-hat control jack"

Does this mean?

a) two separate trigger inputs and one hihat jack
b) a single trigger input that supports dualzone and one hihat jack
c) a "dual" combination of trigger input and hihat jack

Not very clear at all...
