    Thank you Darrel,

    I see that you've been here answering questions patiently for many and for a few years. Kudos to you ....

    The code tells me: Diag Done = 1, Power is parasite, Family $28

    I doubt I hooked these backwards. They were connected to molex 3-pin connectors. Although it is possible to do, I doubt I have inserted with the connection with alignment prong backwards. The two ds18b20 samples from Maxim were both built exactly the same connected to 3ft wire. What I did not do, perhaps, was to ground myself when handling. I'll buy a few more and try again.

    I do not intend to use in parasitic because the application calls for a little safety factor in case of temps above 200 F.

    Attached is the code massaged to my needs (and for future rookies like me). Also, wanted to see the best way to display code within a post.

    Can Anyone tell me how do I reply with code pasted onto a window with the side scroll bar feature I have seen others use?
