"EDIT"
I've been looking around for the pinout on the Z750P to get one switched on for testing, but I'm having trouble tracking this down. Does anybody know if the pinout is the same as on the NPS-700AB (see pic below)? The connector looks the same, but I'm guessing that the pinout could be different. Any help gratefully received .
I noticed you too were looking at the NPS-700ab. And for anyone else, i just found this!
