In order to connect the iScan Pro to your progressive scan TV, video monitor or projector, you will need to determine what type of input connector your set has. Consult your display owner’s manual for more details about requirements of the input connector.

RGB but are sometimes used for Component (YPbPr) signals as well. A standard VGA-to-BNC breakout cable can be used to attach the iScan Pro to any projector or television that has BNC connectors. The connections are shown in Table 1.
Silicon Image, Inc. Color Space Selection The iScan Pro can output video in one of two different color spaces. The first is the Red-Green-Blue (RGB) color space that is commonly used for projectors, displays and monitors that are designed to accept computer video output.

Silicon Image, Inc. With YPbPr connections, the composite sync is always combined with the Y signal. The iScan Pro will automatically do this whenever the color space switch is set to YPbPr. It is not required to configure any of the internal jumpers for any YPbPr device. Wire Color RGB/HV R (Red)
Silicon Image, Inc. iScan Pro User Manual Operation Input Selection The iScan Pro has been designed to detect which one of the three possible input devices are turned on and are generating video signals and then automatically switch to this input. With this capability, you can switch inputs simply by turning one input device on or by turning another device off.
Silicon Image, Inc. Since nearly all televisions sold are CRT-based, it is likely that the gray bar setting is the safest for your display. However, LCD and DLP-based projectors and displays do not suffer from burn-in so it is safe to use the black bar setting. Picture Controls The iScan Pro provides the ability to adjust five picture control settings.
Silicon Image, Inc. Troubleshooting What do I do if no LEDs light when I plug the power supply? The iScan Pro should automatically come “on” when plugged in. Check the connections to the iScan Pro, and to the power source. I f all of these look good, you may have a failed power supply or a failed unit.

Silicon Image, Inc. Insert just the Pr (red) signal into the Pr connector. This should result in a red picture. Remove the Pr and insert the Pb into the Pb connector. This should give you a blue picture. If one or the other of these combinations does not give the expected results, it may be a problem with the output cable or the input connectors on the display.
Silicon Image, Inc. iScan Pro User Manual How it Works Background On a normal television, the video image is made by sweeping an electron beam across the face of the set where it excites phosphors causing them to glow. While repeated scanning across the tube, the television changes the intensity of the beam to vary the brightness of the image.
Silicon Image’s DVDO technology performs even more advanced techniques than those described above. Performing over six billion arithmetic operations per second on the incoming video stream, the iScan Pro uses the data from four video fields during its processing.
The iScan Pro processes steps 2, 3, 4, and 5, but the final quality of the displayed image depends both on the quality of the source and the display device.

Silicon Image, Inc. Appendix A – Internal Jumper Settings These modifications are only required in very rare circumstances. Composite Sync and Sync-on- Green are only required in RGB mode (never Component/YPbPr mode) and typically only with older, large front projectors. The rule of thumb is if you are seeing a picture on your display, then you have the sync settings correct.

There should already be a jumper on two of the pins, closest to the label “NORMAL.” 2) Move this jumper from its current position to the two pins closest to the “SYNC GREEN”...
