Input connection:
The CP-251F 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 labed PC/HDTV on the back of CP-251F.
When accepting a HDTV input use the 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-251F.
The CP-251F can automatically detect the mode and resolution of the PC/HDTV input.
Output connection:
The CP-251F can output a variety of PC resolution and HDTV progressive resolution.
When one of the PC resolution is selected as output, use the 15-pin D-Sub VGA cable to
connect the PC/HDTV output of the CP-251F to the VGA input of a display monitor.
When one of the HDTV resolution is selected as output, use the 15-pin D-Sub to
YPbPr/3 RCA cable to connect the PC/HDTV output of the CP-251F to the YPbPr
input of a HDTV device.
Note:
Use of wrong cable for your selected output will result in an abnormal picture on the
screen.
