Ohh, haha, my mistake. It's one of those days. I ended up searching for the plain CNPS9500 AT manual, and that does have a 4-pin connector (according to the manual), which confused me.
Is there a reason you choose the 9500A (LED version?) over the 9500AT? Are the dimensions as significantly different as the manual seems to suggest? Looking at the manuals for each, I find:
AT: 90mm (width), 115mm(length), 135mm(height)
A-LED: 115mm(width), 88mm(length), 128mm(height)
...I guess those few millimeters make a difference, eh? :doh:
