Installation Runco VX-2cx/VX-2dcx Owner’s Operating Manual 19 PREL IMINARY 3.3 Installation Considerations Proper installation of your projector will ensure the quality of your display. Whether you are installing a projector temporarily or permanently, you should take the following into account to ensure your projector performs optimally. Installation TypeChoose the installation type that best suits your needs: front or rear screen, floor mount or inverted mount. Table 3-2 compares these various installation methods. Ambient LightIn general, minimize or eliminate light sources directed at the screen. Contrast ratio in your images will be noticeably reduced if light directly strikes the screen, such as when a shaft of light from a window or floodlight falls on the image. Images may then appear washed out and less vibrant. Table 3-2.

Installation 20 Runco VX-2cx/VX-2dcx Owner’s Operating Manual 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 3-1. 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 3-1.

Installation 22 Runco VX-2cx/VX-2dcx 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 3-2. Figure 3-2. Projector Placement Vertical and Horizontal Lens Shift If it is not possible to align the projector and screen as shown in Figure 3-2, 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 3-3 and Figure 3-4. Figure 3-3. Vertical Lens Shift (Example Only) ➤ Height Projection DistanceCeiling Ceiling Installation Screen Height Floor Lens Center Projection Distance Floor Installation Lens Center x Lens Center x ScreenLens Center ➤ Base plate to lens center = approx. 5-6 (depending on the amount of lens shift) 50% Height Lens Shift (0.5 x H) 100% Height Lens Shift (1.0 x H) 150% Height Lens Shift (1.5 x H) Screen Center0% Note: This is a general example of lens shift.

Installation Runco VX-2cx/VX-2dcx Owner’s Operating Manual 23 PREL IMINARY Figure 3-4. Horizontal Lens Shift (Example Only) Vertical Lens Shift - VX-2cx: The VX-2cx zoom lenses (Proteus B through F) provide up to 80% of downward vertical lens shift. For example, with a 96 x 54-inch (16:9) screen, you can shift the image up to 43.20 inches (1.10 meters) below the screen center. (Upward vertical lens shift is not possible. Vertical lens shift is not possible in either direction with the Proteus A lens.) Horizontal Lens Shift - VX-2cx: The VX-2cx zoom lenses (Proteus B through F) allow up to 10% of horizontal lens shift in either direction (left or right). For example, with a 96 x 54-inch (16:9) screen, you can shift the image up to 9.60 inches (24.38 cm) left or right of the screen center.

Installation Runco VX-2cx/VX-2dcx Owner’s Operating Manual 25 PREL IMINARY 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. 3.4 Installing the Optional CineWide Lens If you are installing a VX-2 with the optional CineWide or CineWide with AutoScope system, install the secondary anamorphic lens in accordance with the instructions provided with the lens installation kit.

Installation 26 Runco VX-2cx/VX-2dcx Owner’s Operating Manual PREL IMINARY 3.5 Mounting the VX-2 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 VX-2 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 VX-2 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 on-screen display (OSD) controls, to compensate. For detailed instructions, refer to Using the On-Screen Menus on page 37. ➤ ➤ Use only the Runco-approved ceiling mount kit designed for your projector. Install the mount kit according to the instructions provided with it. Note ➤
Installation Runco VX-2cx/VX-2dcx Owner’s Operating Manual 27 PREL IMINARY 3.6 Connections to the VX-2 and DHD Controller Proceed as follows to connect the DHD Controller to the VX-2, 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, pull firmly on the cable access cover to open it. Connecting the DHD Controller to the VX-2 The VX-2 is designed to receive only digital input signals directly from the companion DHD Controller/Processor. All signal sources should be connected to the appropriate inputs on the rear panel of the DHD. The signal from the DHD is then output to the VX-2 projector through a Runco proprietary DVI cable. Use the supplied cable to connect the DVI Output of the DHD Controller to the DHD Input of the VX-2; see Figure 3-6. Figure 3-6. Connecting the VX-2 to the DHD Controller You CANNOT connect a signal source with DVI output directly to the VX-2. It MUST be routed through the DHD Controller for proper operation.Note VX-2 DIGITAL PROJECTOR AC IN 120V 60HZON / OFF Pb Pr Y Video3 IR RS-232 Control S-Video 1 S-Video 2 HD1 HD212 Pr RY GPb B R PrG YB PbH V DVI 1 DVI 2 DVI Out H/V V H Pr RY GPb BH VTRIGGERS RS-232 OutCAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER.
