USB-to-1-Wire/iButton 1.8V Adapter (DS9481R-200) (DS9481R-200)

The DS9481R-200 is a USB-to-1-Wire® adapter for easy PC connectivity to 1-Wire devices. The adapter provides an RJ11 connector with the signals to communicate with all 1-Wire and iButton® devices that support a 1.8V data I/O level. Additionally, the adapter provides the support and signaling to program 1-Wire/iButton EEPROM devices. To provide a total hardware solution, the DS9481R-200 can readily be used with the family of DS9120 socket adapters to create a 1-Wire PC programmer for 1-Wire slave devices (contact factory for more information). The equivalent slave hardware solution for the iButton is the DS1402D-DR8.
