DS9481R USB-to-1-Wire/iButton Adapter Evaluates: 1-Wire Slave and iButton Devices General Description Features M S Driver Support for Windows 7, Windows Vista , The DS9481R is a USB-to-1-Wire adapter for easy PC and Windows XP Operating Systems connectivity to 1-Wire devices. The adapter provides an RJ11 connector with the signals to communicate with all S Enumerates as a Virtual PC COM Port by Use of M 1-Wire and iButton devices that support a 3.3V data I/O the Prolific PL-2303HXD USB-to-UART Bridge IC level. Additionally, the adapter provides the support and S Emulates the DS2480B 1-Wire Line Driving signaling to program 1-Wire/iButton EEPROM and one- Functionality time programmable (OTP)/EPROM devices. To provide S 1-Wire OTP/EPROM Programming Provided a total hardware solution, the DS9481R can readily be Without the Need of an External Power Supply used with the DS9120 socket adapter to create a 1-Wire (12V on OW, 7V on PULSE) PC programmer for 1-Wire slave devices (contact factory S 3.3V Read/Write Operation to 1-Wire/iButton for more information). The equivalent slave hardware Devices solution for the iButton is the DS1402D-DR8.
