VSC 200/200D/300/300D Operation 3-4
Encoder filter — Applies one of the encoder filters to improve the overall image
sharpness. Press the Left or Right cursor buttons to move through the filters:
• STD
• KIL3.58
• HI
Phase adjust — Adjusts the signal’s horizontal phase (the phasing between the
horizontal sync pulses of the video output and the genlock sync pulses) and
subcarrier phase (the phasing between the color burst signal of the video
output and the genlock color burst signal). Press the Up or Down cursor
buttons to adjust the horizontal phase, or press the Left or Right cursor
buttons to adjust the subcarrier phase. See “Setting Up Genlock and Vertical
Interval Switching” on page 3-6 for more information.
System reset — Erases all user preset memory. This has no effect on the factory
preset memory. Press the Up and Down cursor buttons simultaneously to
reset the system, and the confirm reset screen appears. Or, press the Next
button to cancel the system reset.
Confirm reset — Allows you to confirm that you want to erase all user preset
memory. Press the Up and Down cursor buttons simultaneously to reset the
system, or press the Next button to cancel the system reset. If you press the
Up and Down buttons, the user preset memory is erased.
If you previously issued an RS-232 command to enable NTSC/PAL composite
video color bars, performing a system reset will disable the color bars. To re-
enable the color bars, issue the RS-232 command again (see the command/
response table on page 4-4 for more information).
Front panel controls
Centering/pan controls — Shift the physical position of the displayed image
vertically and horizontally if the default cycle or the centering/
pan screen is active.
Freeze/reset — Locks the output display to the current image if the default cycle is
active. When freeze mode is active, the freeze LED is lit. To freeze the image,
press the Freeze/reset button once. To unfreeze the image, press the Freeze/
reset button again. No front panel adjustments can be made until freeze
mode is inactive.
If the zoom, size, or centering/pan screen is active, pressing the Freeze/reset
button resets adjustments for all three of the screens.
If any other screen is active, pressing the Freeze/reset button resets the
setting for only the active screen.
Executive mode — Makes the LCD menus unavailable. This is useful for situations
in which many end users operate the scan converter, and you want to prevent
them from changing the adjustments you have made. To enable executive
mode, press the Up and Down cursor buttons simultaneously while the
default cycle is active. To disable executive mode, press the Up and Down
buttons simultaneously again.
When executive mode is enabled, the centering/pan controls, Freeze/reset
button, and RS-232 port remain active.
