DCC Tools is the Railway Modeller's Companion. It's a selection of handy tools, CV calculators, resources and quick reference guidance notes for railway and railroad modellers, all drawn together into one handy app.

Gone are the days of working out speaker impedance or scale lengths in your head, getting confused over CV29 or long loco address values, or remembering complicated decoder wiring diagrams.

The app does the hard work for you, serving up pin-out diagrams and crunching bytes and bites to generate CVs in seconds; it has something to offer everyone, but is an invaluable companion for digital command control (DCC) users.

Tools currently available in the app include:

• Long address calculator/back-calculator
• Reference library of NMRA-compatible Configuration Variables (CVs)
• CV29 calculator/back-calculator
• Generic CV/bit calculator
• Advanced consisting/MU calculators
• DCC decoder wiring pin-outs
• Speaker impedance calculators
• Scale calculator/back-calculator

...and more!
