Left-clicking on the Write Challenge button writes the 8 bytes of the Challenge text boxes to the DS2703. A
random challenge can be generated into the Challenge text boxes by left-clicking the Randomize Challenge button.
Left-clicking the Randomize Challenge button only changes the text boxes; it is still required to left-click the Write
Challenge button to write the values to the DS2703.
Left-clicking the Compute MAC button will send the command to compute the 20 byte MAC (or Result) and read it
back. The caption below the Compute MAC button indicates if the DS2703 is configured to communicate in
Regular or Over Drive 1-Wire Speed.
The values in the Secret, Challenge and MAC text boxes can be transferred to the text boxes on the main DS2705
EV kit window by left-clicking the Move Values to DS2705 button. This will not write the values to the DS2705. It
simply loads the text boxes with the values.
DS2704 Interface
Connecting a powered DS2704 EV Kit board to the DS91213O with the RJ-11 phone cable, will cause the DS2704
Detected Window to appear. This window allows the user to access some of the functionality of the DS2704.
The user can clear the Secret into the DS2704 by left-clicking on the Clear Secret button. This will load 00h into
the Secret text boxes, as well as in the DS2704. The user can also send the Compute Next Secret command by
left-clicking on the Compute Next Secret button. It is necessary to write the challenge prior to left-clicking the
Compute Next Secret button.
Left-clicking on the Write Challenge button writes the 8 bytes of the Challenge text boxes to the DS2704. A
