Status Indicators
At the top of the dialog box, the status indicators display the current status of
the Genlock input: Locked to External Reference, Internal Clock Locked and
VITC Present. A green light indicates that the particular status is on. These
indicators cannot be edited.
VITC Reader Setting
If you use Automatic VITC detect, the Profile unit uses the range set in the
From and To lines to look for the VITC signals. If Automatic VITC detect is
not used, the unit expects to find the VITC signals on the VITC Reader Line 1
(default 10) or Line 2 (default 12).
