tion.
2. On the DBX card, verify DIP switches 7 (Master assignment) and 8 (Debug Mode) are in the
CLOSED position.
3. Reinsert the DBX card and the Master Controller back into the frame.
4. Once both cards are in the frame, RESET the DBX card into Debug Mode (see figure 1).
- press both bottom soft buttons simultaneously
- while holding the soft buttons, press the RESET button
Once the card comes out of Reset, you can let go of the soft buttons. The DBX card is in debug
