User can set MaxMD using the SW4 dip switch as shown in the below table. If MaxMD is
7, LeakFilm MC scans from 1 to 7 only. In this case any controller with an ID of more than
7 will not be scanned, so it will not be monitored by the LeakFilm MC. To avoid missing any
controllers that are connected to the LeakFilm MC, leave MaxMD set to the default value
of 200.
