Thanks to everyone who replied. I had a brain freeze and was thinking I needed to set the dip switch to the LDEV number, which would be impossible. Once the first email rolled in, I recognized what I needed to do.
Thanks again,
Donald

While you're doing this with the small pointed tool and reading
glasses (alternative to 20-something eyes), I'll add my $0.02 follow-
on suggestion: "Rock" each switch back and forth a couple times;
and try to note if all switches have about the same "tactile feedback".
Because they are so small and even good ones have low resistance
to movement it can be a little hard to tell, but this let me catch a
potential address conflict problem: We have two HASS enclosures.
On one of them one of the DIP switches was so "loose" you could
almost blow on it and cause it to "fall" to the zero (down) position.
My solution; in lieu of major repair (if I understand correctly HASS
DIP switches are *soldered* to the backplane (or so I was told) ):
"Embed" the defective DIP switch in *one* drop of RTV silicone....
Of course that makes it a bit harder to change again if we should
ever need to do that; but in our case odds were low enough I went
for the quick & reliable solution....
