Working Principle
Every license key is a unique key for one and only one option or device type up-
grade or software option, coded with a serial number.
During system startup, the operating software reads the EEproms to check the en-
abled hardware options and to check the device type. The read device type leads
to a filter within the hardware access level of the operating software to ensure that
only the dedicated M/E are controllable by the user.
