Getting Started

Power Supply Cable

Connect the power cable to the board and plug the other end into a power
outlet. To power up the board, place the power switch (S10) in the ON
position. When power is supplied to the board, the LED (D13)
illuminates.

After the board powers up, the on-board flash memory, which ships
pre-programmed with the factory design, automatically configures the
Stratix II GX device. The CONF DONE LED (D14) illuminates, signaling
that the Stratix II GX device is configured.

If the board does not power up after the power cable is
connected, make sure that the power switch (S10) is in the ON
position.

Setting the Clock
Circuit Switches

Set the DIP switch S8 and slide switch S9 per the instructions listed in

Table 2–2

.

To use the on board oscillator, the slide switch (S9) needs to be in the OSC
position. However, to use the SMA connectors J5 and J6, the slide switch
needs to be in the SMA position. The I/O standard of the pattern generator
should be set to LVPECL, LVDS, LVHSTL, SSTL, or the HCSL level.
