 1 . Composite Video: Use a Composite video cable to connect the composite video 
 output of the source equipment to the connector labeled 
 "C-Video" on the back of the Video Scaler.
 2 . S-Video: Use a S-Video cable to connect the S-Video output of the source video 
 equipment to the connector labled " S-Video" on the back of the 
 Video Scaler.
 S-Video provides improved performance over Composite Video and is 
 recommended over composite.
 3 . YCbCr input: Use a 3 RCA-to-3 RCA YCbCr cable to connect the YCbCr output of 
 the source video equipment to the connectors labled YCbCr on the 
 back of the video scaler. Please note the plugs' color have to match
 with the color of the RCA Jacks. YCbCr component provides the best 
 picture quality among all three inputs, and should be used whenever 
 possible.
 4 . Computer RGB with H&V Sync: Connect the source computer's VGA output
 signal to the HD 15 connector labled "PC In" on the 
 back of the Video Scaler.
 Note: This Computer inputs signal is not sclaed, but is available for pass-through
 when the Video Scaler is in the PC In (Bypass) mode.
 Connecting the scaled output to your projector, PDP, or LCD Display
 5 . The HD-15 D-Sub connector is shared by PC/RGBHV output and HDTV/YPbPr output.
 When PC/RGBHV output resoultion (VGA to SXGA) is selected, use the HD-15 to 
 HD-15 VGA cable to connect the output to the PC input of your display monitor.
 When HDTV/YPbPr output (480p, 576p, 720p, 1080i) is selected, use the HD-15 to 
 YPbPr 3 x RCA cable to connect the output to the YPbPr input of your HDTV display.
 Note: Use of wrong cable for your selected output will result in an abnormal picture
 on the screen.
