5.1 Manual Control
Referring to the front panel image on page 6, the Power and Input selection
switches have LEDs above them to indicate that the power is “ON” and/or an
Input selection has been made. Simply press the Power switch and then press
the appropriate input selection push button.
To the right of the Video Input selection area are the control push buttons for
MENU select, Increase (+), Decrease (-), and ENTER. Pressing the MENU push
button causes the OSD (On-Screen Display) menu to appear. See Section 5.2
below for a detailed description of the OSD menu system.
5.2 Using the On-Screen Display Menus
Regardless of whether you operate the Converter/Scaler from the front panel
or using the IR Remote Controller, it is necessary to become familiar with the
On-Screen Display (OSD) menu system in order to take full advantage of the
capabilities of this product.
5.2.1 Menu Navigation
Press the “MENU” button to display the OSD Menu. Use the front panel
controls marked “+” and “-“ to navigate to the desired function and then press
the ENTER button to make the selection. Next, use the “+” and “-” buttons to
make the adjustment and press the ENTER button to save your selection. To
leave the OSD Menu, highlight the word “Exit” in any menu and then press the
ENTER button.
When using the IR remote controller, press the MENU key to activate the OSD
Menu. Use the arrow buttons to navigate to the desired menu selection then
press the “OK” button. Next, use the arrow buttons to make the adjustment
The Converter/Scaler’s OSD Menu is organized in two levels. The rst level allows
selection of the main menu functions (Video, Color, Output, OSD Characteristics,
Audio, Information, and Exit). The second level allows specic adjustments or
operational selections to be made. The table below and on the following page
shows the relationship of the high level and secondary menu functions that are
used to make up the OSD. To use these functions, proceed as follows:
Display the OSD Menu and use the Decrease (-) push button to move upwards
and the Increase (+) push button to move downwards through the menu list.
Use the ENTER push button to select the desired high-level menu item (Video,
Color, Output, OSD Characteristics, Audio, Information, or Exit).
-9-
Navigate to the specic parameter you wish to adjust and then press the ENTER
push button to make the selection. Use the Decrease (-) and Increase (+) push
buttons to select a different value for the parameter (e.g., change output resolution
or change brightness). Use the Exit selection to leave the OSD Menu.
Note 1: The Output sub-menu provides user-selection of the desired output resolution.
Please be aware that some output resolution settings can cause an apparent malfunction if
the selected resolution is not compatible with the connected display device.
CAUTION: Make certain your display device can reproduce the resolution you select
BEFORE you select it.
Note 2: The OSD sub-menu provides user-selection of the On-Screen Display location
and appearance to suit personal preference. You can change the default settings if you
wish, or simply leave it at the factory setting.
Note 3: Since Video and Audio Lip-Sync can be lost in digital television systems, this unit
provides a secondary menu item called “Delay” under the Audio high level menu selection.
An audio delay can be introduced to restore proper lip-sync. Use this function if you hear
audio before the video portion of the program appears to make the corresponding sound.
Note 4: The Info sub-menu contains technical information. If you have problems with this
unit and require assistance, a technician may ask you to read information from this menu
as part of the troubleshooting process.
5.3 RS-232 Protocol
The DVI-3551a is equipped with a RS-232 serial control port. The connection
between the DVI-3551a and PC host controller should be made with an RS-232
modem cable.
