No my reading is that you are moving R46 so that you use the dipswitch
instead of the fixed pullup. To make the dip switch work you have to
move the "hard coded" resistor. I see no mention of moving resistors
when setting different settings on the dip switch (which would be silly
after all), so if the dip switch had been preinstalled and the resister
pre configured for dip switch use, then life would have been much much
simpler.
Of course if the thing could be made easily to power up when power was
applied some people would also find life much simpler, but the current
version can't without some hacking being done.
