Quick Start — DDS 100, cont’d
Using the LCD Screen
The DDS 100’s LCD screen informs you of status changes, and it provides access to menus that allow
you to adjust the image and its parameters. The screen normally cycles through two default screens
continuously. The first displays the DDS model, and the second displays the video input horizontal
and vertical scan frequencies. If the video scan rate is out of range, the default cycle screens change to
“Signal Out of Range” followed by the horizontal and vertical frequency screen.
The Menu button allows you to exit the default screens and advance from one menu to the next. The
Next button allows you to step through the adjustment/selection screens within a menu. The front
panel cursor buttons (Up, Down Left, and Right), and in some cases the centering/pan controls, can be
used from the menu screens to make adjustments and select parameters. The menu sequence is:
Menu button: Zoom/Size/Pan Controls
Next button: Zoom — Adjust the zoom view of the image.
Next button: Size — Adjust the horizontal and vertical size of the image.
Next button: Centering/pan — Center or pan the image.
Menu button: Filter Controls
Next button: Horz. Filter — Select 1 of 4 filters. Select the filter that improves the image
detail the most.
Next button: Vertical filter — Select 1 of 10 filters. Select the filter that reduces the amount of
image flicker the most.
Menu button: Configuration Controls
Next button: Output Res. — Select an output resolution:
VGA 680x480 SVGA 800x600
MAC 832x624 PLASMA 852x480
XGA 1024x768 HDTV 720p
PLASMA 848x480 PLSMA 1280x768
PLSMA 1370x765
Next button: System Reset — Erase all user preset memory. (Resetting does not affect factory
presets.)
Menu button: Exit Menu
Menu button: Recycle through the zoom/size/pan controls menu.
Next button: Display the default cycle screens.
Front Panel Controls
Centering/pan controls — Shifts 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 the
freeze function 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.
If the zoom, size, or centering/pan screen is active, pressing the Freeze/reset button resets
adjustments for all three of the screens.
If the horizontal filter, vertical filter, or any output resolution screen is active, pressing the
Freeze/reset button resets the setting of only the active screen.
Executive mode — Makes the LCD menus unavailable. This is useful for situations in which many
end users operate the scaler 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. To
disable executive mode, press the Up and Down buttons simultaneously again.
When executive mode is enabled, the centering/pan controls and the RS-232 port remain active.
