DBX Boot Code Upgrade

Once the Boot Code for DBX is upgraded to 0.0.3, it is compatible with the MCII-e System Controller.

Before you upgrade your DBX Boot Code:

• verify the DBX Boot Code version is 0.0.2 or earlier.

• make sure the PC running AZedit is close to the Master Frame. The upgrade must be done in the Master Frame in a DBX system.

1. On the Master Controller (NOT the MCII-e), verify DIP switch 7 (S1) is in the CLOSED posi-

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 mode.
