Figure 14. Connect Menu Showing Serial Connection Options

Before the software is configured, it is necessary to set jumper J16 on the CDB5464U board to either the
UART or SPI communication. To select UART communication, install jumper J16 in the SSEL to UART
position. To select SPI communication install jumper J16 in the SSEL to SPI position.

To select UART communications, position jumper J16 to the SSEL to UART position, and select UART in
the Serial Port Selection window (see Figure 15).
