Recently I have been installing SoundTraxx 885840 Tsunami 2 TSU-BH1 2 Amp Digital Sound Drop in Decoders in my Bachmann Diesels and I noticed some CVs with decimals (CV1.407).
The CVs with decimal numbers are not decimal numbers, they are Index designators.

The latest Decoders have so much information SoundTraxx added three index layers to store the additional CVs.
To access indexed CVs, CV31 Index 1 =16 (Read Only), *CV32 Index 2 = (), must be in front of any CV with a 1.,2. or 3. index designator in front of the CV number.
*CV32 Index 2 = 1 (Indexed CV page1)
*CV32 Index 2 = 2 (Indexed CV page 2)
*CV32 Index 2 = 3 (Indexed CV page 3)
