The DS9490B is a USB bridge and holder for a single F5-size iButton. The iButton is securely held
behind a latched door. 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. Both adapters are based on the DS2490 USB to 1-Wire
bridge chip.
