Chapter 3: Operation
Operation Notes
When using the AES-3981 module, observe the following operation
notes:
•
If you change parameters within 16 seconds after the AES-3981
banner first appears on the VFD, your changes will not be saved.
Parameter changes that you make after this 16-second delay will be
saved and restored if the module loses power and must be restarted.
•
Although the effect of a parameter change may appear to be
immediate, the module requires 20 seconds to save the latest
change. If another change is made during these 20 seconds, the first
parameter change and the second parameter change will not be
saved until 20 seconds after the second parameter change. There is
no limit to the number of changes that can be made within 20
seconds of each other. However, none of these changes will be
saved until 20 seconds after the last parameter change.
•
The AES-3981 module automatically sets its parameters to the ones
saved last.
•
When adjusting frame delay using the
DlyRange
parameter, the
range of vertical phase (
VPhase
) is limited to two lines less than a
full frame when the
DlyRange
is set to the maximum value. When
DlyRange
is less than maximum, the full frame line range is
available for adjustment in the
VPhase
parameter.
CAUTION
Failure to observe these Operation Notes will result
in accidental changes to the module’s parameter
settings.
