Overview
This page lists the numbers and names for all of the Configuration Variables defined by the NMRA Standards, including manufacturer-unique ones, used in TCS decoders.
| NOTE: This page refers only to TCS Non-sound decoders Version 88 to [current Version], as well as all WOWSound decoders Version 4.x. |
You can read the NMRA Standards for Configuration Variables (CV's) (Document No. S-9.2.2) for yourself on the NMRA website: NMRA Standards and Recommended Practices
| NOTE: Not all CV's listed on this page are supported by TCS, and not all supported CV's are universally supported by all products. For example, RailCom® configurations, lighting output assignment, and other features which require hardware support may not be applicable to your decoder. Pay special attention to the CV Addendums for your specific decoder. If you are unsure what your decoder is, you can read CV 249 the Decoder Hardware Model Identifier. If you are unsure if your decoder supports a feature, visit the specific product page for your decoder on TCS' Website for a full list of features. |
