VGA to DVI-I
Scaler Box
Operation Manual
CP-252
1. Features:
1. CP-252 is a high performance PC/HDTV two-way scaler that
accepts analog RGB input(VGA) and converters to DVI-I (d analog
RGB) output.
2. The input to the CP-252 is analog PC or HDTV signal in the format either
RGBHV, YPbPr, or(YCbCr).
3. The output of the CP-252 is d analog PC or HDTV signal in the
format of digital RGBHV bitstream plus analog RGBHV, known as
DVI-I(Integrated digital and analog).
4. The input resolution is automatically detected while the output resolution
and refresh rate can be selected through OSD menu and front panel
push buttons.
5. 48 MB frame memory for frame rate conversion.
6. Output picture adjustment on brightness, contrast, color, RGB level,
and H-V position.
7. DVI output enables an all digital rendering of video without the losses
associated with an analog interface and is ideal for use with digital
display such as LCD, plasma and DLP projectors.
2. What's included:
The following items are included in the standard package.
1. VGA to DVI scaler box.
2. VGA cable x 1
3. YPbPr 3 RCA to VGA adaptor cable x 1
4. DVI cable x 1

3.Installation
3.1 Input connection:
The CP-252 can accept both PC and HDTV inputs. When accepting a PC
input use the 15-pin D-sub cable to connect the output of a PC device to
the input connector labled PC/HDTV on th back of CP-252.
When accepting a HDTV input use a 15-pin D-sub to YPbPr/3 RCA cable to
connect the YPbPr/output (or YCbCr) of a HDTV device to the PC/HDTV input
connector of the CP-252.
The CP-252 can automatically detect the mode and resolution of the
PC/HDTV input.
3.2 Output connection:
The CP-252's can output a variety of PC resolution and HDTV progressive
resolution, in both digital and analog format.
To use CP-252's digital output select DVI-D in the Output Setup of the menu,
and use DVI cable to connect the DVI output of the CP-252 to the DVI input
of a display monitor, or HDTV device. See 3.3A
To use analog output of the CP-252, select DVI-A in the Output Setup of the
menu, and use the DVI to VGA adaptor to tranfer analog output into VGA
configuration, which can subsequently connect to the VGA input of a display
monitor through a VGA cable when one of the PC resolution is selected as
output; or connect to the YPbPr input of a HDTV device through a VGA to
YPbPr/3RCA adaptor cable when one of the HDTV resolution is selected as
output. See 3.3B
Note:DVI to VGA adaptor is not included in the standard package,
and has to order separately.
