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.

Train Control Systems' Manufacturer ID Number is 153.

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.
