DS1921K
______________ General Description
The DS1921K Thermochron™ iButton
®
Starter Kit
provides the basic hardware for a quick evaluation of
Maxim’s Thermochron i
Button family that
communicates using the 1-Wire
®
protocol. The kit uses
the USB port of a Microsoft Windows
®
-based Personal
Computer running Vista
®
, XP SP2 (or higher), or
Microsoft Server Operating Systems Windows 2003 or
2008. The kit includes a DS1921 Thermochron i
Button
and all hardware required to communicate with it. The
DS1921K is also capable of evaluating any other
iButton, including the high-capacity Thermochrons
(DS1922L, DS1922T, and DS1923), the Hygrochron™
(DS1923), and the temperature-only i
Button (DS1920).
Please note that the DS1921 is the only i
Button
included in the kit. All other i
Buttons may be purchased
separately. The easy setup process includes the free
download of 1-Wire drivers and the OneWireViewer
demonstration software to easily communicate with
i
Buttons through the PC’s USB port. The download site
for the free 1-Wire drivers and bundled OneWireViewer
is found at:
http://www.maxim-ic.com/1-wiredrivers
For software developers who wish to create custom
i
Button applications, Maxim provides documentation
and a free library of source code examples at
http://www.maxim-ic.com/ibutton
under the Software
Development Kits link. Please check our website
regularly for software updates.
To evaluate plastic-packaged 1-Wire devices instead of
the i
Button form factor, use the DS9090K instead of the
DS1921K. To evaluate any i
Buttons other than
Thermochrons, see the DS9092K.
