ZIP. Save the EV kit software to a temporary folder

and uncompress the ZIP file.

2) Install the EV kit software and USB driver 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 software

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.

SPKR_R+/SPKR_R- oval pads, or plug headphones

into J206 headphone jack.

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 the USB

driver was installed successfully.
