A connector is used to connect two [[sub-system|sub-systems]]. 

The connector allows you to pair one or more //outputs// of a sub-system with //inputs// in another sub-system. When a block which is marked as an //input// is connected to an //output// it will be replaced by the output block. 

When several outputs are connected to one input, their contributions are summed.
