Controlling and Powering the PGA450-Q1 EVM via the USB Interface Board
The PGA450-Q1 EVM is shipped with a USB interface board that provides a link from the PC-controlled
GUI (described later) to the EVM. Connect the USB interface board to the PGA450-Q1 by connecting the
30-pin female header on the interface board to P6, the male 30-pin header on the PGA450-Q1 EVM. The
TI logo on the interface board should face up when it is plugged in.
