3.0 PACKAGE CONTENTS
Before attempting to use this unit, please check the packaging and make certain
the following items are contained in the shipping carton:
• 1xDVI-3410aVideotoDVIConverter/Scaler,or
1x DVI-3420a Video to VGA Converter / Scaler

Model Number, Serial Number, and Invoice Number available for reference when you call.
4.0 CONNECTING THE HARDWARE
The rst step is to connect a video source to the input of the Scaler and to
connect its output to a display device. Below you’ll nd pictures of the unit
showing the locations of the input, output and power connectors.
DVI-3420a Input / Output Panels DVI-3410a Input / Output Panels
4.1 Connecting the Input
The DVI-3420a and DVI-3410a Converter / Scalers accept standard denition
Composite Video, S-Video or Component Video inputs. Composite Video may be
connected to the unit via an RCA input connector. S-Video can be connected via
the 4-pin mini-DIN Connector. Component Video may be connected via the 8-pin
mini-DIN Connector using the provided 3x RCA to 8-Pin mini-DIN breakout cable.
4.2 Connecting the Output
The DVI-3420a Converter / Scaler outputs analog RGBHV or YPbPr formats.
When a PC signal output is required, use an HD-15 (VGA) cable to connect
the output signal to the desired destination device. If you wish to connect this
-4-
product to an Analog HDTV display device, please use a high quality HD-15 to
Component Video (3x RCA) adapter cable.
The DVI-3410a provides digital RGB output signals via a DVI connector. For
best results, use DVIGear’s Super High Resolution™ DVI cables for this output
connection.
Note: Proper signal levels are very important to the operation of this product. If improper
operation of the unit occurs and the unit has power, the most likely cause of the problem is
high or low signal levels, use of a low quality cable, or the use of a wrong input cable.
4.3 Connecting Power to the Unit
This unit is shipped with an AC Power Adapter that converts 100~240 VAC @ 5060 Hz to 5VDC. Connect the AC Power Adapter to the unit. Take care to insert
the locking plug into the DC power connector on the unit and rotate a quarter turn
clockwise so that it locks securely into position. Plug the AC Power Adapter into
anactiveACpowersocket;thegreenpowerLEDshouldbeilluminated.
4.4 Getting the Best Results
There are many factors affecting the quality of results when scaling video signals.
Some basic precautions will ensure the best possible performance from this
product.
Output Display Device – The quality of the output signal will depend largely
upon the type and quality of display device used.
Using Native Resolution – It is always best to set the output resolution of
the scaler to the native resolution and refresh rate of the display device. This
allows the unit’s scaling engine to do most of the work, which usually results in a
superior picture.
Distance between the Video Scaler and the Display Device – This factor
has signicant inuence on the picture quality. Long distances are possible,
but special measures should be taken in order to avoid cable losses. These
measures include using high quality (coax-type) VGA cables and premium DVI
cables, such as DVIGear’s Super High Resolution™ cables. Line ampliers or
digital repeaters may also be necessary.
Output Connection Cables – Low quality cables are susceptible to interference.
They degrade signal quality due to poor impedance matching and cause
elevated noise levels. Therefore, cables should be of the best quality. Coax-type
computer cables are recommended because of their superior internal shielding
characteristics.
Interference from Nearby Electrical Devices – These can have an adverse
effect on signal quality. For example, an older computer monitor often emits
very high electromagnetic elds that can interfere with the performance of video
equipment in its proximity.

6.0 TROUBLESHOOTING
Other than checking for faulty cables, the only common problem is choosing an
incorrect Input or Output Setting. Make sure the display is capable of handling
the resolution and refresh rate selected. Also be sure to use the correct type of
cable for the output format selected (RGB or YPbPr).
