Working with iButtons
In order to communicate with an iButton, the Dolphin iButton reader must make
proper contact with the iButton during the time frame of the communication session.
Intermittent contact can result in slow data communication or the need for re-
attempts.
To transfer data between iButtons and Dolphin iButton reader:
Make sure that both the iButton and the iButton reader are clean and dry.
Touch the iButton reader against the iButton you want to communicate with. The
reader and the iButton must have full surface-to-surface contact for data transfer to be
completed.
Keep the iButton reader touched against the iButton until the application generates a
beep or displays a message on the Dolphin’s screen indicating the data transfer is
completed.
IButtons supported by Dolphin with iButton Reader
The types of iButtons that Dolphin iButton reader may read and write data to depends
