The DISTRIMODEL team provides specialist retailers and model makers with the explanatory note of the digital programming applied to HO scale engine equipment. This document is available for download only. Indeed, depending on the questions of the modelers, we can change the manual in order to benefit the model railroad community.


You will also find here the function sheets of the sound and non-sound decoders.


We also offer plugs for the Z21® application. To do this, in the search area of our site, enter the reference of your model. In the product sheet, go to "attached documents" then click on the file to import into the application installed on your smartphone and or tablet.
