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.

When using the clock speed DIP switch bank (S8), set switches 1-5, 7, and 8 in the closed position, and switch 6 in 
the open position.
