Hopefully simple j tech laser hookup question

I have the molex mini fit Jr cable hooked up to H4 instead of using the screw terminals and going into H2. Does that just mean I hook up the black and yellow wires to H1 since I’m not using the screw terminals?

I have no idea I would contact J-Tech for sure on this one to make sure everything is correct before burning a hole through the universe once turned on lol

hahaha are you familiar with lasers?

I attempted just the letter A, and went to apply and get a G code. I get this message. What am I doing wrong? Also directory field was blank
