+ | You will encounter two address ranges in the NMRI DCC standard, two-digit addressing (called short addressing) and four-digit addressing (called long or extended addressing). The number of digits refers to how many hexadecimal digits are transmitted/ | ||

+ | DCC decoders store the addresses in Configuration Variables (CVs). Each decoder vendor may have different set of CVs to store the digits. Refer to the docs that came with your decoder. | ||

+ | Stands for Automatic Train Control. Within MERG usually refers to a series of kits for automating train running on DC layouts. These kits are capable of controlling layouts from a simple end to end shuttle up to quite complex arrangements. The abbreviation may also be found as a more general reference to automatic train control, model or prototype. | ||

+ | ===== Auto Reverse Module | ||
- | An auto reverse module is used in DCC to prevent shorts in reversing loops and other situations where the polarity of two lines must be reversed for a train to run through. It works by reversing the polarity if a short is detected. If the short is eliminated then the new polarity is accepted and is kept. One auto reverse module can protect several track sections provided that only section break is being bridged by a loco at any one time. | + | An auto reverse module is used in DCC to prevent shorts in reversing loops and other situations where the polarity of two lines must be reversed for a train to run through.
