Each VSCP node have a standard set of register you can read about here. Some of them are possible to change for end users and some are not changeable but instead set by the maker of the module.
The Manufacturer device ID and the Manufacturer sub device ID registers which are in the register range 137-144 (0x89-0x90) are example of registers set by the manufacturer. These eight positions can be used in any way a manufacturer of modules like and on this page we define how we use them. Other may have a totally different use.

The User id's (132-136) can be used by a similar way by a user. Typical is to have installation location information here and such similar information that may be handy to have when a module is installed in a not easy to get to location.
