5. Description of Diagnostic Engine
Selector
During initialization of the Diagnostic Software the Selector will first execute the required Basic Diagnostic Nuclei
(nuclei of which the names start with the word "Basic") to ensure correct operation. In case one of the basic diagnostics
fails an error code and message will be communicated to the outside world via the RS232. In case all basic diagnostics
are passed successfully, the selector will activate the appropriate diagnostic mode.
