The output port A,B,C,D connected with the device such as
monitor(all D2 model monitors),outdoor camera(e.g.DPCD241),and DPC-D211 series without ID function model.
The output port A,B,C,D connected with DPC-D211-xx-ID
series with ID function model.
The output port A,B,C,D connected with DPC-D218ID series
door station.
Please note that DPC-D24x (like DPC-D241-1) and DPC-D218 can not be
connected to the same DBC4, If it happen,please use two DBC4.
The same situation as DPC-D211 and DPC-D218 model.
