GLOSSARY Roadster / Mirage S+ User’s Manual A-7 The distance between the front feet of the projector and the screen. Also called “Projector-to-Screen Distance”. Always use the correct Christie throw distance formula to calculate the proper throw distance (±5%) required for your lens. Throw ratio = throw distance / screen width. Typically used to differentiate lenses. Balance of red-to-green necessary for realistic representation of NTSC signals. The ability of a projector to synchronize to inputs with frequencies within a specified range. The frequency at which images are generated. Vertical frequencies vary amongst sources. Also called vertical scan rate. The difference between the center of the projected image and the center of the projector lens. For this projector, this value is expressed as the maximum percentage of the image that can be projected above or below the lens center without degrading the image quality. Vertical offset ranges depend on the type of lens in use, and whether or not the image is offset horizontally at the same time. The signal that is used by display devices (such as projectors) to generate an image. This term also refers to the output of video tape/disk players and computers. An optional device that converts NTSC 3.58, NTSC 4.4, PAL, PAL-N, PAL-M or SECAM to RGB video. A specific type of video signal, such as NTSC, PAL, SECAM. This projector can automatically recognize and interpret the incoming standard and display accordingly. Screens do not reflect equally in all directions. Most light is reflected in a conical volume centered around the “line of best viewing”. Maximum brightness is perceived if you are within the viewing cone defined by the horizontal and vertical viewing angles. The color temperature of white used by the projector. The area of an image that is white only. For example, a full white field is an image that is white everywhere. A 10% white field is a white area (usually rectangular) that occupies 10% of the image; the remaining 90% is black. A high-end digital component video signal. A high-end analog component video signal. Sometimes called YUV, Component, or Y, R-Y, B-Y, the YPbPr signal by-passes the video decoder in this projector. See YPbPr. The adjustment of image size by means of a zoom lens.

Appendix C Serial Communication Cables Roadster / Mirage S+ User’s Manual C-1 A serial link of RS232 or RS422 enables ASCII communication with the projector so that it can be controlled remotely from a PC or other controller. From a PC, connect a standard 9-wire RS232 serial cable to the RS232 IN port located on the side of the projection head. Or, for long-distance (>100 ft.) links with an RS422-compatible PC or controller, connect RS422 cable to the RS422 port.

Appendix D Throw Distance Roadster / Mirage S+ User’s Manual D-1 Always consult this Appendix when planning a projector installation. See also 2.3, Projector Position and Mounting. Calculating Throw Distance Figure D-1. Calculating Throw Distance Correct throw distance depends on the screen size and lens present—the larger the image needed, the greater the distance you must allow between the lens and screen. Once you know the screen size and lens type present, you can calculate the precise throw distance you require by using the appropriate formula as found in this appendix. Throw distance is the distance between the projector front feet and the screen (Figure D-1). This measurement is not necessarily parallel to the floor—i.e., the projector and screen may both be inclined. NOTE: If your projector is tilted up or down in relation to the screen, typical in large venues or elevated installations, throw distance still represents the smallest measurement between the screen and front feet center axes. Figure D-1 provides the recommended throw distance formulas for each of the “Compact” Thunder Lenses. Pre-calculated throw distances for the complete range of lens types and screen sizes appear in the charts and graphs on the following pages. Refer to these examples to quickly determine the proper throw distance (±5%) for your installation and lens.
