NI shall have no responsibility whatsoever for the performance of the third-party add-ons. So, I have an annoying issue with communicating with this power supply. It s a bad design from this point of view. Will try when I get the time.
I tried the changed VIs but no luck. Hi, im not sure exactly which pin i think 4 but there is one pin from the DB9 that should go to a separate 12v ps. I’m also not a fan of initialize to default values. I’ve made a quick library attached and the VIs for writing voltage and current to the power supply work.
