Connect the regulated 5V power supply to the appropriate power adapter. Plug the 5V line into the J12
(5V POWER JACK) connector on the Personality board. Turn the 5V power supply ON. The OS image
pre-loaded in the 3-Stack should boot and the operating system should appear at the Personality board’s
LCD display.
Software development mode:
• Assemble the three boards together.
• Plug the 5.0 volts DC power into the Debug board DC power jack.
• Press S4 on the Debug board to “1” to power on the 3-Stack system.
Demonstration mode:
• Assemble the Personality and CPU Engine boards together (without the Debug board).
• Plug the 5.0V DC power into the Personality board DC power jack, and the 3-Stack system will be
powered on directly.
