DS9490R - USB to 1-Wire / iButton Adapter

The DS9490R is a USB bridge with 1-Wire RJ11 interface to accommodate 1-Wire receptacles and networks. The DS1402D-DR8 (Blue Dot™) can readily be used in conjunction with the DS9490R to create an iButton PC reader. (The DS9490R connects to the USB port and then the DS1402D-DR8 connects to the DS9490R through an RJ11 connection.) The DS9490R is based on the DS2490 USB to 1-Wire bridge chip.
