In the context of DCC it means the coding of each loco or other decoder, which ensures that it identifies the signals intended for it. | + | Address is the unique identification of anything.

+ | 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. | ||

+ | An ampere is a measure of current flow. It is roughly defined as 6.28 X 10^18 electrons passing a point in one second. From a formula perspective one amp equals one volt divided by one ohm. If you had a one volt battery connected across a one ohm resistor, you would expect to measure one amp of current flow around the circuit. | ||

- | The unit of current. It is defined as the constant current which if maintained in two straight parallel conductors of infinite length, of negligible cross-section and placed one metre apart in vacuum, will produce between the conductors a force equal to 2×10-7newton per metre length. | ||

- | 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.
