2.2.2 Connecting the FTDI Digital Controller

To connect the FTDI digital controller on the EVM board to the computer, align and firmly connect the USB connector to the J15 connector. Verify the connection is snug; a loose connection can cause intermittent operation. A 100 mil header (J9) is available for external communication.

Table 2-5 lists the J9 pin definitions. To use external communication, close jumper J12 to disable the connection to the FTDI controller.
