Installation Vidikron Vision 85 Owner’s Operating Manual 19 PREL IMINARY Throw DistanceThrow distance is the distance measured from the front of the projector to the screen. This is an important calculation in any projector installation as it determines whether or not you have enough room to install your projector with a desired screen size and if your image will be the right size for your screen. You can quickly estimate the throw distance by taking the width of the screen and multiplying it by the lens throw ratio; see Figure 3-2. The result of this calculation tells you roughly how far back the projector should be positioned from the screen in order to project a focused image large enough to fill the screen. Figure 3-2. Estimating Throw Distance The Vision 85 offers a throw ratio of between 1.86 and 2.45. For example, with a 100-inch wide screen, the Vision 85 has a throw distance range of between 186 inches (4.72 meters) and 245 inches (6.22 meters). The Vision 85/CineWide offers a throw ratio of between 1.92 and 2.45. For example, with a 100-inch wide screen, the Vision 85 has a throw distance range of between 192 inches (4.88 meters) and 245 inches (6.22 meters). Estimating Throw Distance Throw Distance (TD) = Screen Width (w) x Lens Throw Ratio Screen width (w) TD Vision 85 Throw Ratio: 1.86 to 2.45 Vision 85/CineWide Throw Ratio: 1.92 to 2.45
Installation 20 Vidikron Vision 85 Owner’s Operating Manual PREL IMINARY Vertical and Horizontal Position Proper placement of the projector relative to the screen will yield a rectangular, perfectly-centered image that completely fills the screen. Ideally, the projector should be positioned perpendicular to the screen and in such a way that the lens center and screen center are aligned with each other, as shown in Figure 3-3. Figure 3-3. Projector Placement Vertical Lens ShiftIf it is not possible to align the projector and screen as shown in Figure 3-3, you can use the lens shift controls to center the image on the screen. Lens shift is generally expressed as a percentage of the screen height or width, as shown in Figure 3-4. Figure 3-4.

Lenses vary in their shift capabilities. No particular lens or projector is used in this example.
Installation Vidikron Vision 85 Owner’s Operating Manual 21 PREL IMINARY The Vision 85 provides up to 50% of vertical lens shift in either direction. For example, with a 96 x 54-inch (16:9) screen, you can shift the image up to 27.00 inches (0.69 meters) above or below the screen center. Folded OpticsIn rear screen applications where space behind the projector is limited, a mirror may be used to fold the optical path, as shown in Figure 3-5. The position of the projector and mirror must be accurately set. If you are considering this type of installation, contact your dealer for assistance. Figure 3-5. Folded Optics Other ConsiderationsOther considerations and tips that can help improve your installation: Keep the ambient temperature constant and below 35°C (95°F). Keep the projector away from heating and/or air conditioning vents. Changes in temperature may cause drifts in the projector circuitry, which may affect performance. Keep the projector away from devices that radiate electromagnetic energy such as motors and transformers. Common sources of these include slide projectors, speakers, power amplifiers and elevators.

Installation 22 Vidikron Vision 85 Owner’s Operating Manual PREL IMINARY 3.4 Mounting the Vision 85 There are several methods for mounting the projector. Depending on your chosen installation, one method may be more suitable than another. Floor Mounting (Upright)In typical front and rear screen installations, the projector can be mounted to a secure and level surface such as a table or cart. Carts are useful when moving a projector during a presentation or from site to site. If possible, lock the wheels when it’s in position to prevent it from being moved during a presentation. Ceiling Mounting (Inverted)For fixed installations, and for those that want the projector out of sight or have a limited space for projector and audience, you can invert the Vision 85 and suspend it from the ceiling using a specially-designed ceiling mount fixture. The projector can also be inverted and placed in an enclosure above and behind the viewing area. Install four feet on the inside bottom surface of the enclosure on which the projector can rest. A variety of materials can be used for this purpose (for example, rubber crutch tips or turntable feet). Adjusting the Projection Angle If the Vision 85 is ceiling-mounted and the screen is significantly lower than the projector, you can tilt the projector at a slight angle by adjusting the ceiling mount. If you do this, you may need to shift the image using the OSD controls, to compensate. For detailed instructions, refer to Using the On-Screen Menus on page 37. ➤ ➤ Use only the Vidikron-approved ceiling mount kit designed for your projector. Install the mount kit according to the instructions provided with it. Note ➤
Installation Vidikron Vision 85 Owner’s Operating Manual 23 PREL IMINARY 3.5 Connections to the Vision 85 and VHD Controller Proceed as follows to connect the VHD Controller to the Vision 85, your video sources, external controller(s) – if present – and AC power. When connecting your equipment: Turn off all equipment before making any connections. Use the correct signal cables for each source. Ensure that the cables are securely connected. Tighten the thumbscrews on connectors that have them. Connector Panel AccessTo access the connector panel, press the door release button so it pops out. Turn the knob clockwise or counter-clockwise and pull gently on it to open the door. Connecting the Projector to the VHD Controller The Vision 85 is designed to receive only video input signals directly from the companion VHD Controller/Processor. Connect all signal sources to the appropriate inputs on the rear panel of the VHD. The signal from the VHD is then output to the Vision 85 projector through an HDMI cable. Connect the HDMI and RS-232 outputs of the VHD Controller to the corresponding inputs of the Vision 85; see Figure 3-6. Figure 3-6. Connecting the Projector to the VHD Controller You CANNOT connect signal sources directly to the Vision 85. They MUST be routed through the VHD Controller for proper operation.Note HDMIHDMI AC IN 100-240V 50-60Hz AC IN 100-240V 50-60HzTRIGGERTRIGGERIRIRRS-232 OUTRS-232 OUT RETURN ENTER DOWN UP LEFT RIGHT RETURN ENTER DOWN UP LEFT RIGHT ON ON MENU MENU ASPECT RATIO ASPECT RATIO STANDBY STANDBY Pb Pr Y Video3 IR RS-232 Control S-Video 1 S-Video 2 HD1 HD212 R/Pr G/Y B/Pb R/Pr G/Y B/Pb H V HDMI 1 HDMI 2 HDMI OutHVTRIGGERS RS-232 OutCAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER.
