This page is a Configuration Variable (CV) calculator for Digitrax mobile decoders. It calculates and displays the hexadecimal values to be programmed into the CVs from a "user friendly" set of options below. This avoids having to calculate all of the values by hand. Note that there is no way to select your decoder at present: some older decoders will not have all of the features described. See the decoder handbook to determine which features your decoder has.

To use this page, simply select the required options from the list below (qll numerical parameters are decimal, and in most cases expressed as percentages of full scale values). Then click the "Calculate CVs" button at the bottom of the page and the required CV values will be displayed in the box at the bottom.
