ESU 54615 SW1200RS
Rapido GMD SW1200RS Decoder Matching
Rapido goes through each and every sound project and sets it up to best work with what they want for lighting and motor control in that project.
For this reason there are a quite a few changes from the default settings which is why they recommend getting their decoders preprogrammed. Some functions are only available on ESU decoders, this is the reason for the ESU recommendation. If MU’ing (consisting) with a factory sound equipped loco those features would not be available in a non ESU decoder. When consisting it is always easier to use the same brand in each loco in the consist.
Setting Up an ESU 54615 LokPilot V4.0 DCC decoder
This is a list of CVs which would need changes in the 54615 to match the sound equipped LokSound Selects in the SW1200RS. This list is long and will be tedious to manually enter, though it is possible…. As you can see from below, this is why a pre-programmed decoder is recommended on the Rapido products.
- If you attempt this, do it in the sequence below as the order of the index CVs (31 and 32) is important.
If needing a reset: Setting CV8 to a value 8 ON THE PROGRAMMING TRACK, not on the Main, will allow you to start over if a mistake occurs.

As the list demonstrates, purchasing a Rapido locomotive with the ESU decoder installed is much easier, or purchase the ESU decoder from Rapido directly if you are retrofitting a locomotive.
LokPilot/LokSound v4 Obsolescence
The v4 decoders became obsolete in 2019 when parts required to manufacture them were discontinued. The LokSound V5 DCC replaced them.
