Hardware Setup

The PC and printed circuit board (PCB) should not be
connected via the USB until after the evaluation software has
been installed satisfactorily (see "Software Setup" on page 2).
To set up the hardware:
1. Connect the USB 2.0 cable first to the PC and then to the
evaluation board. The USB cable is the only connector
needed.
2. If a dialog appears asking about installing software for
new-found hardware, click "Yes, this time only".
The jumpers on the printed circuit board (PCB) are as shown in
Table 1.
