__________________Getting Started
Go to http://www.maxim-ic.com/1-wiredrivers and
download the latest 1-Wire drivers with bundled
OneWireViewer demonstration software. Follow
the instructions on the download site for selecting
the correct driver package and to start the
installation wizard.
IMPORTANT: Do not install the DS9490R into
your USB port until you have completed the
installation wizard in the previous step.
After running the 1-Wire installation wizard, make
sure you have internet available and plug the
DS9490R USB adapter in to a free USB port in
your PC. Windows will continue the installation of
the USB driver but first search the Microsoft web-
site for updates. If you do not have internet
available, the USB driver installation process can
hang up for more than 10 minutes before it times
out.
Plug the RJ-11 Modular connector of the
DS1402D-DR8 Blue Dot Receptor into the
DS9490R USB adapter.
Optionally snap the iButton into the key fob. This
makes easier removal of the iButton from the Blue
Dot Receptor.
Start OneWireViewer software by clicking on its
icon. This application may also be found under
Microsoft Start under the folder ‘‘1-Wire Drivers
x86’’.
Snap the iButton (optionally with key fob) into the
Blue Dot Receptor and you will see its address
displayed. Click on the address to access
screens that show all the functions of each
i
Button. Then, follow the instructions for
missioning and reading the contents of a
Thermochron.

__________Software Development
For developing applications for the Thermochron as
well as other iButtons, Maxim offers three software
development kits (SDKs):
1-Wire SDK for Windows. This SDK is aimed
primarily at PC host environments running Microsoft
Windows. The kit contains sample programs in C#,
VB.NET, VB 6.0, C, and Delphi, along with HTML
documentation for help in utilizing our Windows APIs.
These APIs include the 1-Wire API for .NET, the much
smaller 1-Wire API for Microsoft’s Compact .NET
Framework (Windows CE/Mobile), and the TMEX API
at the lowest level. Download here:

ic.com/products/ibutton/software/tmex/index.cfm.
1-Wire API for Java. This is the foundation for
developing robust 1-Wire and i
Button software on
platforms that have a Java Virtual Machine. It includes
the above-mentioned OneWireViewer utility and its
Java source code. It can be found here:
http://www.maxim-
ic.com/products/ibutton/software/1wire/1wire_api.cfm.
1-Wire Public Domain Kit. This kit includes a public
domain API and example programs written entirely in
C and designed to be portable across multiple
computer operating systems, handheld operating
systems, and microcontroller platforms. The kit
contains many sample 1-Wire applications written in
C. The SDK’s download page is here:
