The D2-260 and D2-250-1 support local expansion. The D2-260 supports local expansion up to five total bases (one CPU plus four expansion bases) and the D2-250-1 supports local expansion up to three total bases (one CPU bases plus two expansion bases). Following are the modules required for expansion:
