NMRA CV 8 - Manufacturer ID

CV8 contains the NMRA assigned ID number of the manufacturer of this decoder. The currently assigned manufacturer ID codes are listed under the Standards section of the NMRA Website. The use of a value not assigned by the NMRA will immediately cause the decoder to not be in conformance of the NMRA Standards.

CV 8 is classified as a Read Only CV. The CV contains a value which cannot be overwritten; however, it is possible to "write" a value to this CV. Doing so may perform a "Macro" such as a Factory Reset, or other operation(s). See below some examples from TCS:

CV 8 "Macros"

CV 8 offers multiple "macro" options which allow you to quickly configure certain aspects of the decoder on the fly. Most macros will perform a sequence of operations internally within the decoder, meaning you would not need to perform each of those operations individually, and can instead use one single command. CV 8 can also be used to save and load User Presets, perform a factory reset, and more!

CV 8 Macros may be programmed on the mainline or a programming track; however, it is strongly recommended that you use a dedicated programming track when performing a factory reset so as to avoid any addressing conflicts.
