Product Details

The DS9481R 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 3.3V data I/O level. Additionally, the adapter provides the support and signaling to program 1-Wire/iButton EEPROM and one-time programmable (OTP)/EPROM devices. To provide a total hardware solution, the DS9481R can readily be used with the DS9120 socket adapter to create a 1-Wire PC programmer for 1-Wire peripheral devices (contact factory for more information). The equivalent peripheral hardware solution for the iButton is the DS1402D-DR8.
