Front Panel

1 Component Video input (either YPbPr and YCbCr formats)
2 Stereo Audio input associated with the Component Video input
3 Infrared Sensor
4 Status LEDs – Indicates selected source type
5 Menu/Enter – press to access OSD Menus, acts as Enter key for menu selection
6 Multi-function Key – see note below

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 (when required), a wide array of input formats and
resolutions. Since you can specify the output resolution of this Converter /
Scaler, it is advisable to know the optimum (native) resolution of your destination
display and set the unit’s output resolution accordingly. Please consult your
owner’s manual in order to determine your display’s native resolution.

Since the output signal format is HDMI (digital only), you must use a display or
other destination device that has a compatible HDMI or DVI input in order to
use this product. You can connect the output of this unit to an HDMI destination
device (e.g. HDTV display) using an HDMI cable, or to a DVI destination device
(e.g. PC display) using an HDMI to DVI cable.

Connect the appropriate cables to all inputs and output taking care to use the
highest quality cables. Please note that low quality cables can cause serious
image quality degradation, as well as limit the distance between the source and
destination devices and the Converter / Scaler. Cable selection is especially crucial
for HDMI/DVI cables due to the high bit-rates of the digital signals. For best results
use DVIGear’s Super High Resolution™ (SHR™) DVI and HDMI cables.

After the signals cables are connected, connect the External AC Power Adaptor
and power ON the unit.

Note 1: This product utilizes a special “Twist-Lock” DC power connector to prevent the power
cable from coming loose. Insert the connector into the socket just as you would with the other
power adaptors. Once inser ted, gently twist the connector right or left 90 degrees to lock it
in place.

The AV-PC to HDMI Converter / Scaler can be operated either from the front
panel controls or via the supplied IR Remote Control unit. Since IR is the
control method preferred by most users, please take a moment to familiarize
yourself with the location and function of the control buttons on the IR Remote
Control unit.

5.1 Using the On Screen Display Menus

Regardless of whether you operate the scaler from the front panel or with the IR
Remote Control unit, it is important to become familiar with the On-Screen Display
(OSD) Menu structure in order to take full advantage of the capabilities this product
has to offer.

-5-

5.1.1 Menu Navigation

Press the MENU/ENTER button to display the OSD menu. Once the menus are
displayed, the “+” and “-” keys are used to navigate through the menu. The “+”
will advance the curser forward (right) or down and the “-” will advance the curser
backwards (left) and up. Once the desired function has been chosen, press the
MENU/ENTER key to select the function. Once the function has been selected,
use the “+” and “-” key to increase or decrease the desired value, then press the
MENU/ENTER to save the adjustment. To exit the OSD menus use the “+” or “-”
key to scroll through the functions until the curser is on Exit and press the MENU/
ENTER key, or simply press the MENU/ENTER key repeatedly.

For remote control access, press the MENU key on the IR Remote Control unit
to display the OSD menus. Use the arrow keys to navigate through the OSD
menus. Once the function has been chosen, press the OK key to select it and
use the arrow keys to make the desired adjustment. Press the OK key to save the
adjustment. Press the EXIT key to escape from the OSD menus.

5.1.2 Menu Structure

The OSD Menu structure is as follows:

Main Menu

Video Menu Color Menu Output Menu OSD Menu Info Menu

Contrast User VGA H-Position Input
Brightness Normal SVGA V-Position Output
Hue Warm XGA Time Out Version
Sat Cool SXGA Background
Sharpness UXGA Exit

V-Position1
Exit

Note 1: H-Position and V-Position are only present when Component Video or PC modes
are selected.

Note 2: The PC menu is only active when the PC Input is selected as the source.

-6-

The Video Menu or PC Menu appears when either of these modes are selected
as inputs. Please note the differences in the menu structure above.

The Color Menu allows selection of four (4) color temperature presets:

Warm Picture has a slightly reddish appearance

Cool Picture has a slightly bluish appearance

Normal Picture has a calibrated color temperature

User User-definable color temperature

The Output Menu allows you to specify the output resolution you want the
Converter / Scaler to produce. For example, if you are using an HDMI display
that can only accept a 1080i HDTV input signal, set the output resolution of the
Converter / Scaler to 1080i. Keep in mind that setting the resolution can cause
an apparent malfunction if you select a resolution that your display device cannot
accept. Therefore, be certain you know what resolutions your display device can
accept BEFORE making these menu selections.

The OSD Menu allows you to customize the way the On-Screen Display appears
when it has been accessed. You can change the default settings to suite your
personal preferences, or simply leave the factory default settings.

Lastly, the Info Menu contains technical information. If you have problems with the
scaler 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 AV-PC to HDMI 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 device source device
direct to a compatible display with a short cable. This will aid in the elimination of
a source being the issue. If the signal is present under these conditions, make
certain that power is present to the scaler. If it is, check the cables for damage.
The cable should be undamaged and short as possible and of premium quality as
discussed in Section 4.

As a final step before contacting technical support, using the IR Remote Control unit,
press the RESET key, which will return the unit to the default factory settings

After trying the above suggestions should the problem still persist, contact your
dealer for additional suggestions. Should the dealer’s technical personnel be
unable to assist you, please contact DVIGear via telephone at [phone]
(United States and Canada); international callers may dial [phone], or use
e-mail at [e-mail].
