How Grodans Paradis AB use the manufacturer registers

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. Others may have a totally different use.

Register Name Description of use
137/0x89 Manufacturer device ID Year when this device was manufactured.
138/0x8A Manufacturer device ID Month of year when this device was manufactured.
139/0x8B Manufacturer device ID Day of month when this device was manufactured.
140/0x8C Manufacturer device ID Code for the person that released and inspected it.
141/0x8D Sub manufacturer device ID Hardware board reversion. 0="A", 1="B"...
142/0x8E Sub manufacturer device ID Currently not used.
143/0x8F Sub manufacturer device ID Currently not used.
144/0x90 Sub manufacturer device ID Currently not used.

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.
