Rules on compatibility between the cartridge and the base unit
The major index of the base-unit version must be greater than or equal to the major
index of the cartridge-application version.
Example: The base unit with a version V1.05 (major index = 1) and an application
with a version V2.00 (major index = 2) are not compatible.
If this rule is not observed, a major fault occurs and Sepam displays the message
