The spelling of the word "DCC OC" may seem confusing at first, but it can be broken down using phonetic transcription. "DCC" is pronounced as "di si si" with emphasis on the first syllable, representing the acronym for "Digital Command Control." "OC" is pronounced as "oh si" with emphasis on the second syllable, representing the abbreviation for "Onboard Computer." Together, they form the term used to describe model train technology that allows for remote control through a computerized interface.
DCC OC stands for "Digital Command Control Output Compare," which refers to a specific feature found in the field of model railroading and digital command control (DCC) systems. In model railroading, DCC systems allow hobbyists to control and operate multiple locomotives and other accessories on their layout using a digital control system instead of traditional analog methods.
The term DCC OC specifically relates to the output compare function within a DCC system. The output compare feature allows hobbyists to synchronize various actions and events in their model railroad layout. By linking specific commands, such as speed changes, lighting effects, or sound functions, to a specific point or event on the layout, the DCC OC feature makes it possible to achieve a higher level of realism and operation.
For example, a model train passing over a section of track equipped with a trigger mechanism can activate a sound effect or a crossing signal. The DCC OC function ensures that the corresponding action occurs precisely at the desired moment by comparing the locomotive's position or condition to predefined triggers or conditions within the DCC system.
Overall, DCC OC is an advanced capability of digital command control systems that allows model railroaders to enhance the realism and interactivity of their layouts by synchronizing desired actions with specific events or operating conditions.
