2-15 INSTALLATION AND SETUP S-Video The video decoder input panel provides simultaneous connection of both a composite video source (INPUT 3) and an S-Video source (INPUT 4). If connecting an S-Video source, use the 4-pin mini DIN connector orthe Y and C BNC con- nectors (luma and chroma) atINPUT 4-do not use both as inputs. See Figure 2.14. Figure 2.14. Connecting S-Video AUDIO for INPUT 4:To control audio levels in an audio/visual system, connect pre-amplified (line level) audio inputs to the “IN 4”left and right channel audio inputs located near the top left corner of the rear input panel. Then connect external audio amplification equipment to audio “OUT”for sound output. Audio connection cables require standard RCA type phono plugs. NOTE: If you want to loop an S-video signal through to another projector or display device, see Video Loop Through.
2-16 INSTALLATION AND SETUP Video Loop Through To loop a single incoming video signal input (connected at the video decoder) through to anoth- er projector or display device, use the empty connector(s) adjacent to this same input as described below. Composite Video Loop Through CONNECTIONS:See Figure 2.15. From your source, connect a composite video signal to INPUT 3using either the small phono plug or the adjacent BNC. Connect a second cable from whichever INPUT 3connector is free to one of the composite video inputs of the next display device or projector. Continue this looping method for each projector, using either the phono plug or the adjacent BNC as input into INPUT 3, then using the other connector as an output (i.e., loop through). Whether you use the BNC or the phono plug as input or output depends on the type of cable you have on hand and what type of connectors are on each end. If desired, connect one audio signal to any projector as usual. VIDEO TERMINATION:In the Preferencesmenu, make sure “Video Termination” is checked for the final projector only. All other projectors must have this option unchecked in order for the signal to continue. For other types of display devices in the chain, typically a “Hi-Z” switch posi- tion is needed. Figure 2.15. Connections for Composite Video Loop Through
2-17 INSTALLATION AND SETUP S-Video Loop Through CONNECTIONS: See Figure 2.16. From your source, connect an S-video source signal to INPUT 4using either the 4-pin mini DIN or the 2 adjacent BNCs labeled Y and C. Connect a second cable from whichever INPUT 4 connector is free to one of the S-video inputs of the next display device or projector. Continue this looping method for each projector, using either 4-pin mini DIN or the 2 adjacent BNCs as input into INPUT 4, then using the other connector(s) as an output (i.e., loop through). Whether you use 4-pin mini DIN or the 2 adjacent BNCs as input or output depends on the type of cable you have on hand and what type of connectors are on each end. If desired, connect one audio signal to any projector as usual. VIDEO TERMINATION: In the Preferencesmenu, make sure “Video Termination” is checked for only the final projector. All other projectors must have this option unchecked in order for the signal to continue. For other types of display devices in the chain, typically a “Hi-Z” switch posi- tion is needed. Figure 2.16. Connections for S-Video Loop Through
2-18 INSTALLATION AND SETUP Extra Video- COMPOSITE OR S-VIDEO If you want to use an extra video source in addition to the video source(s) connected at INPUT 3 or INPUT 4connect either a Composite or S-Video source to INPUT 1as shown in Figure 2.17. Do not connect both types here simultaneously. NOTE: For additional video inputs, install an optional Composite/S-Video Input Module at INPUT 2. Figure 2.17. Connecting an Extra Video Source to Input 1 Optional Inputs Optional modules from Runco allow you to increase your total number of inputs and/or accom- modate different signal types, whether analog or digital. Any one of these modules can be installed in the area labeled INPUT 2. They include: zRGB Input Module zRGB Active Loop Thru Input Module zRGB Buffered Amplifier Input Module zComposite/S-Video Input Module zPC250 Analog Input Module zSerial Digital Input Module zHDTV Serial Input Module (available Spring 2000)
2-19 INSTALLATION AND SETUP 2.5 Power Connection Plug the projector’s high-current 13-amp rated line cord into the line input socket located in the lower right corner of the rear panel of the projector, then plug the 3-pronged end of the line cord into a grounded AC outlet. Input voltage to the projector must be capable of supplying between 100 and 240 VAC, 50 or 60 Hz. The power source must be capable of supplying 1200 watts of power to the projector. See Section 5, Specifications for all power requirements. WARNING Do not attempt operation if the AC supply and cord are not within the specified voltage and power range. Caution: Once the projector is turned off, the lamp cooling fans will continue to run for approximately five minutes to ensure that the projector and lamp have sufficiently cooled, at which point the fans will automatically shut off. To avoid thermal stress to the lamp, never unplug the line cord while the lamp cooling fans are running. Do not unplug the projector in order to power down. 2.6 Operating Orientation The projector is set up at the factory for use in a front screen, floor mount orientation. If your ini- tial installation is ceiling mount or rear screen, displayed images may be upside down and/or reversed. To correct, you must change the image orientation from within the Preferences menu (you may prefer to do this before physi- cally installing the projector in its final posi- tion/orientation). In the Preferences menu, highlight and select the “Image Orientation” pull-down list. Select from Rear, Inverted Rear, Front or Inverted Front according to your intended installation. See Section 3, Operation for further informa- tion. 2.7 Leveling For most installations, the lens surface of the projector is parallel to the screen-this prevents ‘keystoning’ of the image (i.e., an image with non-parallel sides). In addition, the projector must be kept level from side-to-side in order for the lamp to function safely. To make small cor- rections to the projector’s level, rotate each leg as necessary to raise or lower. For angled instal- lations, see “Special Mounting”under 2.3, Projector Position and Mounting earlier in this section. Figure 2.18. Adjusting the Feet Height !! !
2-20 INSTALLATION AND SETUP 2.8 Zoom, Focus & Lens Offset Once the projector is properly set up and producing an image, you are ready to make quick lens adjustments. Zoom If you have a zoom lens installed, turn the textured ring of the lens barrel to decrease or increase the size of the image at the current throw distance. NOTE: Do not touch the lens surface. Focus At the lens opening, turn the focus tab until the image is as sharp as possible. Lens Offset To ensure that the image is located as desired, turn either or both of the front screws next to the lens. The top screw (vertical) will raise or lower the image, the bottom screw (horizontal) will shift the image left or right. Try to achieve the desired overall image position and best brightness while obtaining a rectangular image. If the brightness looks uneven, or the edges do not look per- fectly straight, the projector may not be in the optimal position for your screen. See 2.3, Projector Position and Mountingfor full details. Lens offset ranges are also listed on page 5-1. Further display adjustments are available through keypad commands and on-screen menus-refer to Section 3, Operation. 2.9 Serial Port Connections You may wish to use equipment other than the keypad for controlling the projector or for per- forming other special functions. Such equipment-such as most personal computers-requires a serial interface for sending and receiving communications through the serial ports on the projec- tor. Note that there are two different types of serial communication ports on this projector as described below. If using a computer RS-232 Ports From computers or automation systems, connect an RS-232serial communication cable between the controlling device and the projector serial port labeled RS-232 IN-this 9-pin D connector port is located near the bottom center of the projector’s rear control panel (see Figure 2.19). Then set the projector baud rate to match that of the computer or automation system(changing the baud rate is described in 3.7, Adjusting System Parameters and Advanced Controls). NOTE: Refer to Appendix Dfor complete cable wiring details.
2-21 INSTALLATION AND SETUP Figure 2.19. RS-232 Serial Connection to a Computer RS-422 Ports Some systems can provide RS-422serial communications (often through a plug-in adapter or external converter) rather than the more common RS-232. RS-422 communication has differen- tial “transmits-and-receives” and is generally better suited for long distances than is RS-232 com- munication. RS-422 is not compatible with RS-232-connecting one to the other could damage the equipment at either end. If you wish to control the projector with a computer and/or other controlling device having RS- 422 capability, connect RS-422serial communication cables between the computer (or other device) and either (or both) of the projector serial ports labeled RS-422-these 6-pin XLR con- nector ports are located near the upper right corner of the projector’s rear control panel (see Figure 2.20). Use an RS-422port onlyif your equipment has RS-422 capability-always first consult the documentation supplied with your equipment.
2-22 INSTALLATION AND SETUP Figure 2.20. RS-422 Serial Connection to a Computer WARNING Do not use an RS-422 port unless you are using a computer with RS-422 capability. The voltage levels of this signal can damage incompatible equipment. If using multiple projectors Serial Communications RS-232 NETWORK:To control multiple projectors with a computer/controller having an RS- 232 interface, chain the projectors together by connecting the RS-232 OUTconnector of the first projector (already connected to the computer/controller) to the RS-232 INconnector of the next projector in the chain. !! Figure 2.21. Adding Another Projector via RS-232
2-23 INSTALLATION AND SETUP RS-422 NETWORK:To control multiple projectors with a computer/controller having an RS- 422 interface, you can chain the projectors together by connecting the RS-422 PORT 2connec- tor of the first projector (already connected to the computer/controller) to the RS-422 PORT 1 connector of the next projector in the chain. Figure 2.22. Adding Another Projector via RS-422 For either type of network, continue connecting projectors in this manner until you’ve reached the last projector in the chain, so that only the last projector has an empty RS-232 OUT (or RS-422 PORT, if applicable). See examples on the following page.
2-24 INSTALLATION AND SETUP Figure 2.23. Assorted Networks Communication parameters such as baud rate must be set to match the particular controlling device-refer to the documentation that came with your controlling device in order to determine the proper baud rate. See 3.7, Adjusting System Parameters and Advanced Controlsif you need help changing the projector baud rate from its default of 38400. NOTES: 1)To avoid damage, connect only properly wired serial communication cables. See Appendix Dfor details. 2)It is recommended that each RS-232 communication cable be no more than 25 feet in length. Use high quality cables. l;kjd;flkj;lkasjd;lkjfa;sdff ;laskdjf;lieuiodmca:LKs eopedjivncfhasp;rpprgm oiawoedfpawreoifasjdfll;kjd;flkj;lkasjd;lkjfa;sdff ;laskdjf;lieuiodmca:LKs eopedjivncfhasp;rpprgm oiawoedfpawreoifasjdfll;kjd;flkj;lkasjd;lkjfa;sdff ;laskdjf;lieuiodmca:LKs eopedjivncfhasp;rpprgm oiawoedfpawreoifasjdfl l;kjd;flkj;lkasjd;lkjfa;sdff ;laskdjf;lieuiodmca:LKs eopedjivncfhasp;rpprgm oiawoedfpawreoifasjdfll;kjd;flkj;lkasjd;lkjfa;sdff ;laskdjf;lieuiodmca:LKs eopedjivncfhasp;rpprgm oiawoedfpawreoifasjdfll;kjd;flkj;lkasjd;lkjfa;sdff ;laskdjf;lieuiodmca:LKs eopedjivncfhasp;rpprgm oiawoedfpawreoifasjdfl Proj 001 Proj 002 Proj 003 RS-422RS-232 Use either or bothNOTE: Programming for the RS-232 controller must be compatible with the RS-422 controller Use either or both network cable types
