2.2.1 Connecting the FT4232 Digital Controller

To connect the FT4232 digital controller on the EVM board to the computer, align and firmly connect the USB connector to the J3 connector. Verify the connection is snug; a loose connection can cause intermittent operation. A 100 mil header (J15) is available for external communication. Table 3-6 lists the J15 pin definitions. To use external communication, close jumper J1 to disable the connection to the FT4232 controller. When using external I2C, TI recommends to close the J16 and J17 jumpers in the I2C positions, as the jumpers connect the pull-up resistors R43 and R44 to the communication lines.
