The DBush interface links Dunham Bush NC25-4 controller to North's Extensible Object Model. Up to 10 controllers can be accessed from a single NC25. For communications with the NC25-4 to begin, algorithm chip sets of v44.07 or higher should be fitted; these are located on the main board U29 and U30. The GRAPHICS (GRAP) command must also be present in the database chip U28.
