Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
1) Verify that jumpers JU1–JU14 are in their default posi-
tion, as shown in Table 1.
2) Visit www.maxim-ic.com/evkitsoftware to download
the latest version of the EV kit software, 5825ARxx.
ZIP. Save the EV kit software to a temporary folder and
uncompress the ZIP file.
3) Install the EV kit software on your computer by running
the INSTALL.EXE program inside the temporary folder.
The program files are copied to your PC and icons
are created in the Windows Start | Programs menu.
During software installation, some versions of Windows
may show a warning message indicating that this soft-
ware is from an unknown publisher. This is not an error
condition and it is safe to proceed with installation.
Administrator privileges are required to install the USB
device driver on Windows.
4) Connect the USB cable from the PC to the EV kit
board. A Windows message appears when connect-
ing the EV kit board to the PC for the first time. Each
version of Windows has a slightly different message.
If you see a Windows message stating ready to use,
then proceed to the next step. Otherwise, open the
USB_Driver_Help_200.PDF document in the Windows
Start | Programs menu to verify that the USB driver
was installed successfully.
5) Start the EV kit software by opening its icon in the
Start | Programs menu. The EV kit software main
window appears, as shown in Figure 2.
6) Within the DACs tab sheet, press the EXECUTE
button in the Quick DAC Output Voltage group box.
7) Use the GNDS PCB pad for the negative terminal of
the DVM and use the positive terminal to measure the
voltage at the DAC_ test points. Verify that the voltages
measured are 1.25V.
