Configuration
Frame Sync Web Page
The Frame Sync web page ( Figure 24 on page 48 for Local or Reference Bus
reference and Figure 25 on page 49 for Input reference) provides horizontal
and vertical timing and loss of signal controls for the 8985FSP module.
Note The controls available on the Frame Sync page depend on the Output Timing
Source selected on the System Config web page.
Minimum Delay Mode
A minimum delay can be enabled to bypass portions of the frame sync
memory to allow an absolute minimum amount of delay through the
module. To enable this mode, check the
Enabled checkbox. Refer to the Elec-
trical Length Specifications on page 65 for notes on using this mode.
Timing Adjustment
When the Frame Sync option is present and the Local output timing source
is selected, horizontal and vertical timing adjustments can be made on the
output video as required relative to the external reference with the fol-
lowing controls
• H Timing (Pixels) – the horizontal timing can be adjusted in pixels relative
to the external reference.
• V Timing (Lines) – the vertical timing can be adjusted in lines relative to
the external reference.
• Multi-Frame Delay – this control allows you to add up to 6 frames of delay.
When the H and V Timing controls are set to maximum, the total delay
of the module will be 8 frames (when
Minimum Delay Mode is not
selected).
Loss of Signal Operation
Set the operation to be performed by the module upon loss of input signal
when a Local external reference is present (
Auto Blue , Auto Freeze , or Pass ).
When there is no external reference (output timing set to Input), the
module will default to pass the signal to the output.
Manual Freeze Mode
Select one of the radio buttons ( Frame or Field ) to perform a manual freeze
on the output .
