Power up the board.
If the on-board clock is used, ensure that the slide switch (S9) is in
the oscillator position (OSC).
Set switch 6 of the clock setting DIP switch bank (S8) to OPEN.
Set switch 7 of the user DIP switch bank (S7) to OPEN for serial
loopback.
To set the pattern generator to PRBS23, set switch 6 of the user DIP
switch bank (S7) to closed and switch 5 to OPEN.
Set the VOD, preemphasis, DC gain, and equalization values.
This is an optional step. Refer to
to confirm whether the intended settings are written.
Assert the push button switch S2 to reset the data generators and
checkers.
Check the status of LED’s D1, D2, and D3. When all three LEDs are
illuminated, the transaction is successful.
