DIP switches
There are address and mode DIP switches on the DGP board (Figure 4 on page 4). The mode DIP switches are
currently not used. The address DIP switches (1 to 4) are used to identify this DGP to the control panel (assign
the DGP address). A 4-door/elevator controller DGP can only be addressed as DGP 1 to 12 (Figure 5).
