2.3 Power-up the DE2-70 Board
The DE2-70 board comes with a preloaded configuration bit stream to demonstrate some features of
the board. This bit stream also allows users to see quickly if the board is working properly. To
power-up the board perform the following steps:
1. Connect the provided USB cable from the host computer to the USB Blaster connector on
the DE2-70 board. For communication between the host and the DE2-70 board, it is
necessary to install the Altera USB Blaster driver software. If this driver is not already
installed on the host computer, it can be installed as explained in the tutorial Getting
Started with Altera's DE2-70 Board . This tutorial is available in the directory
DE2_70_tutorials on the DE2-70 System CD-ROM .

Connect the 12V adapter to the DE2-70 board
Connect a VGA monitor to the VGA port on the DE2-70 board
Connect your headset to the Line-out audio port on the DE2-70 board
Turn the RUN/PROG switch on the left edge of the DE2-70 board to RUN position; the
PROG position is used only for the AS Mode programming
Turn the power on by pressing the ON/OFF switch on the DE2-70 board
