Properties
Switch the MCM between automatic and manual reference
selection.
If the MCM is set to manual reference selection, this selects
which source is used.
For each of the input references listed, select a numerical
value to assign each input source's priority, with 1 being
the most important.
Once set, the MCM will try to use the input reference source
listed as 1, but if that fails, it will automatically switch to
input reference 2 if it is valid. If the lower-priority input
reference is not valid, the M212 will iterate down to a
lower priority input reference until a higher priority input
reference is restored.
