If you already know about line doublers and have had experience installing these devices, here’s a summary of what is unique about the iScan Plus v2.

Installation

The iScan Plus v2 has 3 input ports and 1 output port. The inputs are auto-sensing and switching which means that they will automatically switch to whichever input is active. The “Input Priority” switch allows you to select which input should be used when more than one is active.

We recommend using S-Video inputs for DVD players, satellite receivers and/or digital cable boxes. For VCRs or laserdisc players, chances are good that using the composite video input will give you a better picture because of the very good Y/C separator in the iScan Plus v2. However, you should try both composite and S-Video to see which works better in your system.

There are two switches that are of interest during installation. The first, the “Input Priority” switch was described above. The second is the “Colorspace” select switch on the back panel and is used to change the output colorspace from RGB to component video (YPrPb), to match the characteristics of your display device. If your display supports progressive 31.5kHz signals on both RGB and YPrPb inputs, we generally recommend using YPrPb due to the increase color controls available.

The iScan Plus v2 has a single video output connector which is the same connector used by the computer industry to connect computer monitors to computers. This connector is called an HD- 15, or VGA connector and has Red, Green, Blue, H Sync and V Sync signals. However, if Component Video (YPrPb) colorspace is selected using the colorspace switch, Y, Pr and Pb signals are placed on the Green, Red and Blue signal pins, respectively.

A high quality VGA-to-VGA computer monitor cable should be used to connect the iScan Plus v2’s output to devices that can only accept progressive signals through a VGA connector.

A standard VGA-to-BNC breakout cable can be used to attach the iScan Plus v2 to any projector or television that has BNC connectors. Your iScan dealer may stock these cables or, if not, they should be able to recommend a store that does carry them.

A set of three BNC-to-RCA adapters can be used with this same cable for connecting to televisions with component video RCA inputs. In this case, no sync signals are required so the gray (or white) and black wires can be left unconnected. These are available at higher-end video houses or electronics supply stores like Radio Shack.

For RGB devices, the iScan Plus v2 defaults to separate H and V syncs whereas for YPrPb sync- on-Y is used. Inside of the iScan Plus v2 there are two jumpers that can be set to enable sync-on- green and composite sync signals. These are described in Appendix A. These are only needed for high-end RGB projectors, not for television sets. They are never needed if your display has a YPrPb input.

A small gray ferrite is shipped with the iScan Plus v2 power supply module. It should be installed on the end of the small cable coming from the power supply to the iScan Plus v2. Looping the wire through the ferrite twice in the same direction is an easy way of securing it in position and will cause the ferrite to be more effective in removing high frequency noise from the system.
