NABU PC Cable Length Experiment
Does your NABU require a very short serial cable to work reliably? What happens if I press my luck? (80s reference)
I make plenty of mistakes (I'm aware of at least two of them in this video), and I'm open to corrections from people who know more about this stuff. But I back up my assertions here with measurements, and references are included below. So just telling me I'm wrong without a citation is not helpful.
