Chapter 3: Configuration and Operation
•
The
Sync Mode Set
parameter must be set to
Genlock
.
•
Genlock must be available, with a frame rate that matches the operation
standard.
•
Input video must be synced to Genlock.
•
The
SRC (1-8) Bypass
parameter must be set to
Yes
.
Note
If the SRC Bypass Mode parameter is set to Auto, ACO6800
+
will enable
SRC bypass automatically when Dolby data is detected.
Configuring the Switching Mechanism
Three factors control the output channels on the ACO6800
+
:
•
GPI control
•
Alarm severity levels for each input channel
•
Parameters that can be manually switched in CCS Navigator or at the card
edge
Use the following parameters in the
Switch Settings
group of parameters to
define the switch priority levels:
•
Group A or Group B Switch High Priority (the default setting is
GPI Input
)
•
Group A or Group B Switch Medium Priority (the default setting is
Manual
)
•
Group A or Group B Switch Low Priority (the default setting is
Alarms
)
A high priority event overrides a medium priority event, which overrides a low
priority event. The three options are mutually exclusive.
As an example, the current settings might start out in these default values:
•
Group A Switch High Priority:
GPI Input
•
Group A Switch Medium Priority:
Manual
•
Group A Switch Low Priority:
Alarms
By changing the Group A Switch Low Priority setting to
GPI Input
, the
module automatically changes the Group A Switch High Priority setting to
Alarms
. This new setting is exclusive, and will not conflict with the Medium
and Low settings.
GPI Input Control
indicates what happens when a GPI Input is activated—for example,
pressing a button on a panel—when the switching is not triggered by other
higher priority events than
GPI Input
.
