Explanation of Display
Run Timer
The first set of characters (0019 in the example) is a run timer. The run timer counts the normal operation hours,
but does not count standby hours. The run timer displays hours in hexadecimal format. The value of the run
timer is displayed in SAM and CSM. This display will increment based on the amount of time the set has been
on. The display will also be incremented one hour each time the set is turned on.
Software Identification, Cluster, and Version
The software identification, cluster, and version will be shown in the top level SAM menu, and in CSM.
The following format will be used: "AAABBC-X.Y". (Example: A81US1 1.2)
− AAA is the engineering project name (Ex: A81 = A8.1).
− BB is additional specification indicating specific functionality or a region (Ex: US). Processors with the same
engineering project name and function name are interchangeable, except for the languages they support.
− C is the language cluster number within the "BB" software version (Ex: 1 = English/Spanish/French)
− X is the main version number (Ex: 1)
− Y is the sub version number (Ex: 2)
− the main version number is updated with a major change of specification (incompatible with the previous
software version)
− the sub version number is updated with a minor change (backwards compatible with the previous versions)
− Note: A new micro controller is considered to be compatible if it works instead of the old software and the
functionality is not significantly changed.
