## Questions & Answers

**Q: Would this be able to charge a usb device, such as an iphone, if plugged into a home's rj11 land-line phone jack?**
A: NO! This is only to attach special 1-wire sensor networks using rj-11 plug to a USB port on a computer.  This is not a phone device.

**Q: Would this enable serial data transfer directly via the usb? have a device (pinewood derby timer) that uses rj11 output. want to skip the dongle.**
A: You want to look elsewhere.  The DS9490R# adapter is used for communicating with 1-Wire (a communication protocol) devices over USB.  The RJ11 is just a reference to a generic connector used by many devices like old land line phones and the DS9490R#.
