I own and use one for a few years now....it does require COR...logic
can be front panel programmable either active high or active low. It
does require at least 7 VDC either way for consistancy...5VDC will
not cut the mustard. Mine is set up for active high and I am using
12 VDC COR voltage and she is happy. I had inconsistant issues with
+5VDC COR
