The Conditional Router stage sends records to different paths in the flow depending on the criteria you specify. The stage can have one or more output ports, depending on the defined criteria. Output ports are numbered consecutively, starting with 1 (which displays as "port").
The output ports connect to different stages to which the data is to be sent, depending on defined conditions. For example, you can send one set of records to port 1 in case of a successful match, while a different set of records can be sent to port 2 in case of a failed match.
An input record is written to the Conditional Router's output port only if the entire expression evaluates to true.
