*Note: To eject an iButton, insert a straightened paper clip into the side access hole of the DS9490B. Push
the paper clip in the direction of the iButton. A different iButton can then be inserted. The data
contact faces down and away from the embossed ‘i’. Before inserting the paper clip disconnect the
DS9490B from the USB bus.
Each USB bridge contains a unique built-in identification chip. The identification chip is a custom DS2401
that is a 64-bit ID number (see Figure 3).
