    Default DS1821K information

    Hi all,

    Many years ago I was using a Dallas Semiconductor kit, DS1821K, especially design for DS1821 family temperature sensor/ thermostat. I was using it only to program the TH, TL and status registers so I can use the device (DS1821) as a stand alone thermostat.
    Unfortunately I lost the HDD with the DEV1821.EXE file and the hardware involved (or part of it).
    I still have some other parts of other kits (DS9091K, port adaptors, DS9097 and DS9097E and a fair supply of DS1821 chips).
    I would like to make use of them but I no longer have the setup.
    A search on Dallas (now Maxim) site left me empty handed.

    My humble questions to the forum are:

    • Does anyone know where I can find the DEV1821.EXE file to download and some info on the schematic of the hardware?

    • Does anyone know if they have for sure an other kit which can, out of box, work with the target device (DS1821) or its newer versions? I prefer to use this particular device because is the only one I know that comes on a 3 pin package and one of the choices is TO220 (easy to mount).

    • Does anyone have such kit for sale?

    Thank you for your attention!

    Nick

    Isn't the DS1821K just a plain ol' standard DS1821 in a different package?
    Looks like there's a half a dozen hits here on the forums for it (not to mention a fair number of hits in Google).

    Alain,

    You are a life savior!
    Thanks a lot!
    I’ll dig some more for the hardware schematic or for the hardware itself.

    Skimask,

    The DS1821K is a development kit for DS1821 family. The big advantage of the DS1821 family devices (at list for me) is the 3 pin package and especially the TO220 and the fact that once you set a TH, TL and a status bit it becomes a stand alone thermostat. It is true you have only one degree Celsius resolution but for my application is fine.
    Regards,

    Nick

    Ahhh...
    I thought it might be the difference between a TO-92, TO-220, DIP-8, or something along those lines.

    Usually a K at the end of DSxxxx part numbers means a development kit
