EVALUATION BOARD SOFTWARE
INSTALLING THE SOFTWARE
The AD5064 evaluation kit includes self-installing software on CD.
The software is compatible with Microsoft® Windows® 2000 and
Windows XP.
To ensure that the board is correctly recognized when con-
nected to the PC, install the software before connecting the
evaluation board to the USB port of the PC.
1. Start the Windows operating system and insert the CD.
2. The installation software should launch automatically. If it
does not, run the setup.exe file directly from the CD.
3. After installation from the CD is complete, power up the
AD5064 evaluation board as described in the Power Supplies
section. Connect the evaluation board to the USB port of
the PC using the cable that is supplied.
4. When the software detects the evaluation board, proceed
through any dialog boxes that appear until the installation
is completed.
SOFTWARE OPERATION
1. From the Analog Devices menu, click Start > All
Programs > Analog Devices > AD5064 > AD5064
Evaluation Software.
For older PCs, click Start > Programs > Analog Devices
> AD5064 > AD5064 Evaluation Software.
The main window of the AD5064 evaluation software opens, as
shown in Figure 2. The data programmed into the 32-bit input
shift register is displayed. You can select the command bits, the
address bits, and the data bits by clicking the appropriate option
button under each section.
Command Bits

Other commands that the AD5064 evaluation software allows
you to program include the power-down DAC bits, the clear code
register bits, and the register bits by clicking the corresponding
option button under the Select Control Function section and
then clicking Write to Part. You can also set the register bits for
