Configuration Variables (CV) Setter -- HO & N Scales

The CV Setter for HO and N scale locomotives is a precision tool that lets you quickly and easily customize and fine‑tune locomotive performance by adjusting Configuration Variables (CVs) such as speed, acceleration, lighting, and sound.

Designed for model railroaders who want precise control, it features a user‑friendly interface and broad compatibility with NMRA‑compliant DCC decoders and BLI sound‑equipped models. Its compact, portable design includes a detailed manual to guide setup, helping achieve smoother operation and more consistent results across a fleet, whether on the workbench or the layout.
