ESU Loksound decoders are quite complex. More CVs were needed that 255. As a result, ESU designed indexed CVs to expland the number of CV slots. The CVs ranging from 257 – 511 are “indexed”. This means that the meaning of any of these CVs can change depending on the value of the so-called “Index register”. If you change the value of the index register, the meaning and the value of the CV itself will be also changed. This method allows to use every CV between 257–511 several times and solves the problem regarding CV shortage. CV 31 and CV 32, which are also so-called “index register”, determines the meaning of CV 257–511 as well. If you change both the CVs 31 and 32, you simultaneously change the meaning and the values of CV 257–511. Consult the LokSound Instruction Manual for full details.
