Silicon Image, Inc. Scan Plus v2 User Manual

System Requirements

The iScan Plus v2 is designed to interface to progressively scanned display devices that can draw horizontal scan lines at a rate of 31.5 KHz. Normal televisions operate only at 15.75 KHz but HDTVs, data projectors, high-frequency video projectors and computer monitors typically operate at the higher frequency. You should verify that your display is capable of operating at this horizontal scan rate. Your dealer should be able to help answer this question.

The iScan Plus v2 accepts input from virtually any NTSC video source since it can be driven with either an S-Video or composite video connection.

Connections

Inputs

There are three available inputs on the iScan Plus v2. Inputs 1 and 2 connect to devices with S- Video outputs. These connections are sometimes called S-VHS. Input 3 accepts input from any device with an NTSC video output (also called composite video), such as a typical VCR. To connect a cable or antenna input, we recommend running that cable to a VCR and using the composite video output from the VCR to the iScan Plus v2.

We recommend using an S-Video input for a DVD player, satellite receiver and/or digital cable box. For VCRs or laserdisc players, chances are good that using the composite video input will give you a better picture because the iScan Plus v2 typically has better Y/C separation circuitry than most of these devices. However, you should try both composite and S-Video to see which works better in your system.

The iScan Plus v2 will automatically search for and select whichever of the three input ports is active. You can also specify a priority-input choice so that if two or more of the inputs are active, the priority switch indicates which input to use. See the Operation Section for more detail.

Output

In order to connect the iScan Plus v2 to your progressive scan TV, video monitor or projector, you will need to determine what type of connector and what type of color space is used by your set. For some types of connections, you will also need to know which wire of the cable needs to be plugged into which connector on the display device. It is recommended that you also consult your display owner’s manual for more details about your particular configuration requirements.

The iScan Plus v2 uses a single 15-pin VGA-style connector for its output. This is the same type of connector that most computers use to drive computer monitors. A wide variety of monitors and projectors can be used with the iScan Plus v2 but you will need to determine which connector your display device requires, either VGA, BNC, or RCA connectors as described below.

Typical Display Connectors

VGA Connector: One type of input connector that can be found on some TVs and projectors is the same VGA connector used by the iScan Plus v2. This type of connector is typically found on monitors and projectors that are designed to accept input from a computer. High quality male VGA- to-maleVGA cables are available through retailers specializing in home theater or high-end computer stores.
