Oops! They are different parts with different family IDs, so it will
definitely not be recognized.  I was out this weekend, let me look at the
DS18B20 a bit closer before you order.

I wanted to add an external temperature sensor to my T238, but mistakenly
bought a DS18B20 instead of a DS18S20.  I figured I would wire it up
anyways, and unsurprisingly, it doesn't work.  On the off chance it should
work, and doesn't because I screwed up somewhere else, I wanted to ask if
anyone has gotten a DS18B20 to talk to the T238+.  

Otherwise, I'll be ordering the right part on Monday!

Ted
