Breakout Board Power Configurations
Breakout Board Power Supplied by ISA3 (Figure 4-2): The default configuration is to supply power via
the InSight Adapter and InSight Port cable. Ensure the power switch on the InSight Adapter is in the
INT (Internal) position. The power supply of the InSight Adapter is also controlled via the admin
interface. You may need to connect to the admin port of the ISA and issue the “power on” command.
No external power supply should be connected to the Breakout Board when supplying power from the
ISA. The power supply jumper on the Breakout Board should be in the horizontal position, connecting
V_ISA to the center pin. The V_ISA LED will illuminate when power is applied.
Breakout Board Power Supplied by USB (Figure 4-3): The Breakout Board may also be powered via the
USB connector, either using a USB cable plugged in to the USB power adapter included in the
development kit, or by connecting it to your PC. The power supply jumper on the Breakout Board
should be in the lower vertical position, connecting V_REG to the center pin. The V_USB LED will
illuminate when power is applied. When powering the Breakout Board in this way, ensure the power
switch on the InSight Adapter is in the EXT (External) position.
