For people way smarter than me, that document might help.
In my experience,the only value in the standard inverter.conf to change, is the qpiri value. the rest I have always been able to leave as they come with the docker container. The QPIRI one is the one that always changes. But again, for me this has been guesswork always, so much so that I too am stuck with helping someone with a Kodak inverter find the correct value. I have tried everything so far. But nothing. I will keep at it though.
So what I would do if I were you: on a linux machine, connect your serial cable directly to a linux machine. Then, only fiddle with the qpiri value, not the other ones, until you see something different. That is about all I can say atm, sorry for not being more help
