4.0 CONNECTING THE HARDWARE
Please study the following front panel and back panel images in order to
become familiar with connector locations and control functions:
1 Component Video Input: supports YPbPr and YCbCr formats
2 Infrared Receiver
3 Status LEDs: indicates selected source type
4 MENU / ENTER: press to access OSD Menus; acts as the enter key for
menu selection
5 Multi-function Keys: see note on page 7
6 Power ON/OFF: press to power the unit on or off
1 DC Power Input: locking female connector for External AC Power Adapter

3 PC Output: HD15 pin female; connect to a compatible analog RGB,H,V display
4 DVI Input: female connector; connect to a compatible DVI or HDMI source
5 PC Input: HD15 pin female; connect to a compatible analog RGB,H,V source
-6-
Note: The functions of the “+” and “-” keys change depending on whether or not the OSD
Menus are present. When the OSD Menus are present (activated by pressing the Menu
control button), the “+” and “-” keys allow navigation through the various menu parameters.
When the Menus are not present, the “-” key will automatically adjust the picture centering,
color, etc. for the analog input signals (Component Video or PC). The “+” will sequentially
step through the different inputs of the Converter / Scaler.
This Converter / Scaler uses advanced signal processing that will automatically
accept, identify, and scale a wide array of input formats and resolutions. For best
results, it is usually recommended to set the unit’s output resolution to match the
native resolution of the connected display. Please consult your owner’s manual in
order to determine your display’s native resolution.
When using the DVI-D output signal (digital only), you must use a display or other
destination device that has a compatible DVI or HDMI input. You can connect the
output of this unit to a DVI destination device (e.g. PC display) using a DVI-DVI
cable or to an HDMI destination device (e.g. HDTV display) using a DVI-HDMI
cable. Please consult DVIGear for assistance in cable selection.
Referring to the product images in Section 4, connect the appropriate cables to all
inputs and outputs, taking care to use high quality cables. Note that low quality
cables can cause serious image quality degradation, as well as limit the maximum
possible distance between the Converter / Scaler and the source and destination
devices. Cable selection is especially important for long DVI and HDMI cables
due to the high bit rates of these digital signals. For best results use DVIGear’s
Super High Resolution™ (SHR™) DVI and HDMI cables.
After the cables are connected, connect the supplied AC Power Adapter to the
DVI-3331a. Use only the furnished power adapter to avoid the possibility of
equipment damage.
Plug the AC Power Adapter into the unit and into an AC wall outlet and press the
Power button to activate the unit. Verify that one of the red Status LEDs lights up,
indicating that power has been applied to the unit. Press the Power button to turn
the unit OFF / ON again as needed. In the event of a power outage, this unit will
automatically power ON and restore the last used settings as soon as power is
reapplied to the unit.
Note: This product utilizes a “Twist-Lock” DC power connector to prevent the power cable
from coming loose. Insert the DC plug into the power input jack on the rear panel, then
gently twist the plug a quarter turn in the clockwise direction to lock it in place. To remove
the power connection, simply rotate the DC plug a quarter turn counter-clockwise and then
extract the power cable.

The selection of the Video Menu or PC Menu is made automatically based on
the selected input signal. The Video Menu offers additional functions, including
Picture Mode, Scale and NR (Noise Reduction).
The Picture Mode has four settings: User, Standard, Movie and Vivid. When the
Picture Mode is set to Standard, Movie or Vivid, the Brightness, Contrast, Hue,
Saturation and Sharpness adjustments are set to xed values in order to optimize
the appearance of the image. To change these settings, select User in the Picture
Mode menu. Changes made to these settings will be saved to the unit’s memory
and can be recalled at any time by selecting User in the Picture Mode.
The Scale function has ve user selections: Letterbox, Overscan, Panscan,
Underscan, and Full. The Scale function is used to alter the Aspect Ratio
of the output signal in order to achieve a desired format on the display or
destination device. The following are the menu selections for the Scale
function and their effects:
Letterbox
Overscan
Panscan
Underscan
Full
Remaps the picture content to a letterbox format within the new resolution. Best
used to remap source content from 4:3 aspect ratio to 16:9.
Remaps the picture content larger than the original image in order to reduce the
black bars at the top and bottom of a 16:9 letterbox source.
Remaps the picture content to a smaller size than the output resolution and centers
the content in the middle of the image. Best used to remap source content from
letterbox or 16:9 aspect ratio to 4:3.
Remaps the picture content to a smaller size than the output resolution.
Remaps the picture content to full output resolution. This setting should be used
with high resolution data to maximize clarity.
The NR (Noise Reduction) function has four choices: Low, Middle, High and Off.
For most applications it is recommend that this setting be left in the Off position.
The Color Menu allows selection of four color temperature presets:
Warm

The Output Menu allows user selection of the desired output resolution. For best
results, it is usually recommended to set the unit’s output resolution to match the
native resolution of the connected display. Please consult your owner’s manual
in order to determine your display’s native resolution. Keep in mind that selecting
an output resolution that is not supported by your display can cause an apparent
malfunction.
The OSD Menu allows you to customize the way the On-Screen Display appears
when it has been accessed.
The Info 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.
6.0 TROUBLESHOOTING
In the event that the DVI-3331a Converter / Scaler does not appear to be
functioning properly, make certain that the source and all other devices connected
to the unit are functioning correctly by connecting each source device directly
to a compatible display using a short cable. If the signal is present under these
conditions, make certain that power is present to the scaler. Check that all
cables have no signs of damage, are well seated, and are of premium quality
as discussed in Section 4. As a nal step, return the unit to the factory default
settings by pressing the RESET key on the IR Remote Control unit.
If the problem persists after trying the above suggestions, please contact your
