DVI - to - VGA Video Scaler
1. Introduction
1.1 General
The SC-DV-2 is a high performance
PC/HDTV scaler that accepts Digital DVI
input and converts it to analog RGB output
(PC VGA or HDTV Component).
The input resolution is automatically detected
while the output resolution and refresh rate
can be selected through OSD menu and front panel push buttons.
The SC-DV-2 Video Processor combines the functions of a video scaler,
scan-converter, and format transformer and is packed into a compact and
durable metal housing with easy-to-use touch buttons.
The controls include input/output setup picture adjustment, H/V phase
adjustment, System information and many other advanced options.
The SC-DV-2 allows you to specify a resolution and refresh rate for its
output. Then it will output a steady (uninterrupted) VGA signal to your
display device at the specified rate regardless of the input. This effectively
allows any DVI switch, such as HRT's SW-DVI-2A or SW-DVI-4A, to
become a seamless switch. The output timing is constant regardless of what
is happening at the input. So when you switch from one input to another,
the display device does not see any interruption in the signal coming to it.

Model SC-DV-2
1.2 Features
• Converts Digital DVI from any PC (or digital output from a DVD
player) to analog VGA or component output.
• Ideal for use with high-resolution displays such as LCD, plasma, or
DLP projectors.
• The resolution of any PC or HDTV video signal can be scaled up or
scaled down to any other PC or HDTV resolution. It can also change the
frame rate of the output.
• 50 MB Video memory for real-time frame rate conversion.
• Signal format conversion between RGBHV and YPbPr.
• Input: PC(VGA/SVGA/XGA/SXGA) + HDTV(480i 576i 480p 567p
720p 1080i), @ 60 to 85 Hz
• Output: PC
• Automatically detects input mode and timing parameters
• Easy- to- use push buttons and OSD menu control.
(VGA/SVGA/XGA/SXGA) + HDTV(480p/576p/720p/1080i)
2. Installation
2.1 Input connection
The SC-DV-2 can accept both PC and HDTV input in digital DVI format.
Use the DVI-to-DVI cable to connect the DVI output of a PC or HDTV
device to the DVI input connector of the SC-DV-2.
The SC-DV-2 can automatically detect the mode and resolution of the DVI
input.
2.2 Output connection
The SC-DV-2 can output a variety of PC and HDTV resolutions in analog
RGBHV (or YPbPr) formats.
When one of the PC resolutions is selected as the output, use a 15-pin DSub VGA cable to connect the PC/HDTV output of the SC-DV-2 to the
VGA input of a display monitor.
4
DVI - to - VGA Video Scaler
When one of the HDTV resolutions is selected as output, use a 15-pin DSub to YPbPr/3 RCA adaptor cable to connect the PC/HDTV output of the
SC-DV-2 to the YPbPr input of a HDTV device.
2.3 Connection Block Diagrams
In the above diagrams the output of the SC-DV-2 connects to the VGA
monitor via a HD15 Cable and to the HDTV via a HD15 to 3 RCA cable.
Note that the SC-DV-2 is not HDCP compliant. HDCP refers to digital
content protection of some high-resolution DVD players or Satellite
receivers. Depending on the brand of the equipment, if you are playing a
high-resolution HDCP encoded video through the SC-DV-2, you may not
get a picture, or the output of the DVD player may emerge at a lower
resolution!

3.2 Menus and Adjustments
Pressing the Menu button will bring up the OSD menu controls on the
screen as follows:

¾ Output set up
¾ Picture Adjust
¾ HV Adjust
¾ OSD Adjust
¾ System Information
¾ Auto Adjust

Use +, or - to move the arrow cursor to your desired selection, then press
MENU to confirm your selection and enter into sub menu.
When selected, a sub menu for selecting YPbPr/RGB

will appear:
YPBPR …
The SC-DV-2 automatically detects and shows the input format as YPbPr
or RGB. However, you can manually select the YPbPr or RGB to match the
format of your input. Selecting a format that doesn't coincide with your
input will result in an abnormal picture.

Notes
The default output resolution is XGA @ 60Hz.
The unit has non-volatile memory. It saves all your settings before
power off, and recalls those settings on next power on.
Quickly Jumping to XGA or 480p Output
At any time, pressing + and - buttons simultaneously for a few seconds will
reset the output resolution to XGA@60Hz, and other settings back to
factory default values. Pressing the Menu and – together for a few seconds
will choose 480P output mode.
4. Troubleshooting
There are no field serviceable parts or circuits in the device. If you think
that the device is malfunctioning (or you have no picture output), please
first try to reset to factory default settings by pressing the “+” and “-”
buttons (or “menu” and “-” buttons) simultaneously for 2 seconds (See
above).
