2.3.1
Setup
Setup allows user to establish a USB communication connection with CDB5461AU board or select a pre-saved data
file for further analysis.
If the USB is selected, the evaluation software will poll the CDB5461AU, verifying the serial communication link is
ready. At this point USB is checked indicating that the PC has successfully communicated with CDB5461AU eval-
uation board, and device and micro-code version information are read from the board and displayed on the screen.
See Figure 3.
Figure 3. Establishing a USB Connection
If the evaluation software is unable to establish a communication link with CDB5461AU an error message will ap-
pear, indicating that the initial communication has failed. See Figure 6.
Figure 4. USB Error Message
Check to verify that the USB cable is connected properly and the power supply is on and connected properly to the
CDB5461U. Reset the board (press the RESET button on the board) and try to setup USB again.
If Data from Disk is selected, a file selection window will appear as shown in Figure 5. The user can select a pre-
saved data file for further analysis using time domain, FFT, and histogram plots in the Data Collection window of the
software.
