Lock/Unlock
A lock occurs when the signal sent from the MMI via the wake-up/diagnosis distribution line is understood and answered by the connected MOST
control modules; in this way a 'lock (connection)' is brought about. This is maintained until the signal is not received for a longer time 'unlock'.
Man Machine Interface (MMI)
The MMI is part of the PCM2 (on the mainboard). It runs the gateway commands via the wake-up signal line and the diagnosis of the distribution line.
Navigation
The navigation module is designed as a module box which can be pushed into the PCM2 (optional). After inserting, an electronic connector is
automatically opened and the module is integrated into the MOST ring.
MOST Actual Installations List/MOST Required Installations List
All MOST control modules that are connected to the PCM2 are entered in the 'required installations list'. An actual installations list is written and saved
when the PCM2 is started.
