2.3 Power-up the DE2-115 Board
The DE2-115 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
DE2-115 board. For communication between the host and the DE2-115 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
DE2-115 Board ” (tut_initialDE2-115.pdf). This tutorial is available in the directory
DE2_115_tutorials on the DE2-115 System CD.
2. Turn off the power by pressing the red ON/OFF switch before connecting the 12V adapter to
the DE2-115 board.
3. Connect a VGA monitor to the VGA port on the DE2-115 board.
4. Connect your headset to the line-out audio port on the DE2-115 board.
5. Turn the RUN/PROG switch (SW19) on the left edge of the DE2-115 board to RUN position;
the PROG position is used only for the AS Mode programming.
6. Recycle the power by turning the red power switch on the DE2-115 board OFF and ON again .
At this point you should observe the following:
• All user LEDs are flashing
• All 7-segment displays are cycling through the numbers 0 to F
• The LCD display shows “Welcome to the Altera DE2-115”
• The VGA monitor displays the image shown in Figure 2-4
• Set the slide switch SW17 to the DOWN position; you should hear a 1-kHz sound. Be careful of
the very loud volume for avoiding any discomfort
• Set the slide switch SW17 to the UP position and connect the output of an audio player to the
line-in connector on the DE2-115 board; on your speaker or headset you should hear the music
played from the audio player (MP3, PC, iPod, or the like)
