SOFTWARE INSTALLATION PROCEDURES

The

EVAL-AD7403FMCZ

evaluation kit includes a CD

containing evaluation software to be installed on your PC
before you begin using the evaluation board.
There are two parts to the installation:

•

EVAL-AD7403FMCZ

evaluation software installation

•

EVAL-SDP-CH1Z

driver installation

Warning

The evaluation board software and drivers must be installed
before connecting the evaluation board and

EVAL-SDP-CH1Z

board to the USB port of the PC to ensure that the evaluation
system is correctly recognized when it is connected to the PC.

Installing the
