2.3Power-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.

2.Connect the 12V adapter to the DE2-70 board

3.Connect a VGA monitor to the VGA port on the DE2-70 board

4.Connect your headset to the Line-out audio port on the DE2-70 board

5.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

6.Turn the power on by pressing the ON/OFF switch on the DE2-70 board
