DESCRIPTION
The 2-in-1 Fob has a DS2490 chip in its handle to convert 1-Wire signaling to USB communication. In
this way an iButton, 1-Wire chip, or 1-Wire instrument can have a 2-way communication link with its
USB host. Any iButton from the lowest cost to the most sophisticated can be mounted in the angled end
of the fob. A Java-powered iButton in combination with the 2-in-1 Fob provides the equivalent of a Java
smart card with a built in reader. Everything fits in the handle, so there is no cable for the notebook
connectivity. The USB guard protects the connector from debris and mechanical stresses while attached
to a key ring. Pressing the eject latch releases the guard of the 2-in-1 Fob for USB connection.
Together with the appropriate USB device driver, a notebook or desktop computer can read/write the
attached iButton with no cables or other power connections. You can press the Blue Dot with your
iButton for touch-and-go door entry.
By snapping on the Low Profile Blue Dot (DS1402L) to the iButton on the 2-in-1 Fob, the range of the
1-Wire signal can be extended to another Blue Dot receptor or other 1-Wire devices.
