I seem to recall some confusion about the jumper in either the current manual, or the original manual. If you pull the cover, I think there's an explanation printed on the board?
Hm. That's interesting. Yes, I downloaded from the webpage and it is as you wrote. However, I have 2 more pdfs already downloaded with the opposite. Now I'm away from my AXBB, so I can't test it, but if you're there then try it, please. Thanks in advance.
