Windows RDS control software System


The software can run in demo mode without the RDS encoder connected.


Magic RDS 3 - default Windows control software

Note: The RDS encoder contains two types of memory. These are marked as RAM and EEPROM. Like any other computing system the RAM holds all operational data which are also used for transmission whilst the EEPROM is used for the data storage during power-off. By default the button Send will fill the RAM only. The button Store will fill the RAM and also stores the data into EEPROM. The Store button behavior can be changed in Options - Preferences - Buttons.

If the user forgets to store the data into EEPROM, the settings will be lost when the power is disconnected.



FM Transmitter Connection


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.




FM transmitter with only one MPX input provided.



Both stereo encoder and FM transmitter with only one MPX connector provided - loopthrough mode. It is recommended not to use this mode if any of the other connections are possible.







FM transmitter with integrated stereo encoder.




FM transmitter with integrated stereo encoder, Only have a AUX in / RDS in / SCA in .

In case of mono transmission (no stereo encoder used) the RDS encoder input may be left unconnected (since there is no need of external synchronization) or it may be used for the audio signal injection in the case that the FM transmitter has only one input connector.
