Basic rules:

The RDS signal must be fed into modulation signal (added to MPX signal if stereo encoder is used).

If stereo encoder is used, one of its outputs (MPX or pilot tone) must be fed into the RDS encoder input to

meet the synchronization requirement.

Following figures show various situations and corresponding methods of connection:

Separate stereo encoder - default connection.

Stereo encoder with only one MPX output provided.

RDS/SCA input MPX output

FM transmitter with only one MPX input provided.
