The OneWireViewer

The OneWireViewer is a Java™ application for exploring iButton or 1-Wire™ chip features from your PC. It is included in the 1-Wire Drivers installation program.  Before running the program, make sure that a USB port kit (DS9490R + DS1402D-DR8) or a serial port kit (DS9097U + DS1402D-DR8) is connected to the PC. OneWireViewer automatically finds iButtons or 1-Wire chips on the 1-Wire Network and displays their serial numbers with a description of relevant features and menu options. The OneWireViewer supports nearly every feature of the 1-Wire family of devices, including support for temperature, potentiometer, switch, A-to-D, humidity, and memory devices. In addition, device-specific features are included to support the Thermochron, Hygrochron and other devices. The following screenshot demonstrates the interface to the OneWireViewer as well as the temperature log viewer for the Thermochron:

 

The OneWireViewer is installed by default through the 1-Wire Drivers installation as an executable.  Just double-click to run it.  The executable version of the OneWireViewer requires that a Java Runtime Environment (JRE) be installed, but the program does not need an internet connection to run.  Optionally, the OneWireViewer can be setup as a "Java Webstart" application.  To install and start the OneWireViewer as a Web Start application, CLICK HERE.  If the application fails to load, see the OneWireViewer's website.  Also, if you want to download the latest executable version of the OneWireViewer, see the OneWireViewer's website.  For further documentation, please download the OneWireViewer User’s Guide.

Installing Java Web Start

Java Web Start comes integrated in the latest Java Runtime Environment (JRE) from Sun.  To download an run the latest JRE, please visit:  http://www.java.com.  Java Web Start provides a way of running an application that checks a web site first for newer versions of an application and automatically downloads/installs/runs the updated application.  For those with an "always on" internet connection, this might be the preferred method of running the OneWireViewer.

              
Troubleshooting

The OneWireViewer has a built-in message log that will display any "normal" exceptions such as those generated by intermediate contact or lack of 1-Wire adapter features. This is available under the View->Message Log menu option.
