Product Details

The DS9090EVKIT evaluation system (EV system) consists of a DS9490+ USB-to-1-Wire^®/iButton^® adapter for PC connectivity, a DS9120P+ socket board with RJ11 cable, and seven different 1-Wire devices. This EV system provides the special hardware and software system to exercise the features of 1-Wire devices with memory or PIO/switches, except 1-Wire EPROM devices. (EPROM devices such as the DS2502 and DS2506 require a different adapter (DS9481R-3C7) to perform an EPROM write. This adapter can be purchased separately.) 1-Wire EPROM devices are available for sampling.

The EV system software consists of the OneWireViewer (a Java^® program) that runs under Windows ^® OS and comes as part of the 1-Wire drivers installation package.
