Installation Operation, cont’d Installationand and Operation Installation Overview This is an overview of the installation process. You will find detailed installation and operation instructions in this chapter. To install and set up the RGB 201 Rxi interface, follow these basic steps: N 2-2 Sync polarity, sync-on-red and sync-on-blue, and video clamp configuration require opening the interface’s case and should be done before the interface is mounted.
Internal Configuration The interface is factory configured to output RGBHV or RGBS video whose sync follows the input and that is clamped to the back porch. The interface can be configured to output positive or negative sync, output RsGsBs video, or to clamp on the sync tip. All of these reconfigurations require opening the interface’s case. 1. Remove the three screws on each side and the two screws on top of the cover (figure 2-1). Slide cover back slightly, lift straight up.

To force positive or negative sync, reconfigure the jumper as follows: 1. Locate J9, J20, and J21 on the printed circuit board. 2.
Internal sync DIP switches (RsGsBs) The interface is factory configured to strip all sync signals from the red, green, and blue video input signals and to output horizontal and vertical sync separately(RGBHV) or as composite sync (RGBS). Sync on green (SOG or RGsB) can be selected on a rear panel DIP switch. Sync on red, green and blue (RsGsBs) can be selected on internal DIP switches. 1. Locate DIP switch SW2 on the printed circuit board.
Installation and Operation, cont’d Mounting the Interface The interface can be mounted on tabletops, under desks, through desks, or on racks, as described in this section. Tabletop placement For tabletop or desktop placement only, install the self-adhesive rubber feet/pads (provided) onto the four corners of the bottom of the interface enclosure. Under-desk mounting 1.
4. Insert the four wood screws into the pilot holes. Fasten each screw into the installation surface until just less than 1/4" of the screw protrudes. 5. Align the installed screws with the slots in the mounting brackets, and place the interface against the surface, with the screws through the bracket slots. 6. Slide the interface slightly forward or back, then tighten all four screws to fasten it in place. Through-desk mounting 1. If rubber feet were installed on the interface, remove them.
Installation and Operation, cont’d 2-8 2. Insert the machine screws provided in the optional mounting kit (part #70-077-02) through the slots in the through-desk mounting brackets, and loosely secure the brackets to the interface (figure 2-4). 3. Hold the interface with attached brackets against the underside of the desk/table. With a soft pencil mark the location of holes for screws on the desk. Mark the opening, approximately 1.8" x 8.9" ( 4.6 cm x 22.6 cm). 4.
Rack mounting UL guidelines for rack mounting The following Underwriters Laboratories (UL) guidelines are relevant to the safe installation of these products in a rack: 1. Elevated operating ambient temperature — If the unit is installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature.

Installation and Operation, cont’d d BNC output connectors — Connect a coaxial cable between the display (projector or monitor) and these rear panel R G B BNC connectors. H V S For RGBHV (separate H and V sync) output, connect the cables to five BNCs. For RGBS (composite sync), connect the cables to four BNCs. e For RGsB (sync on green, SOG) and RsGsBs (sync on all), connect the cables to three BNCs. Also select the SOG option on the rear panel DIP switch (see item 6 , Dip switches in this chapter.
f DIP switches — This bank of DIP switches is used to configure the interface. The switches control: • DDSP or ADSP • SOG (sync on green) • Serration pulses • Vertical sync pulse width • Mono or stereo audio • Backlight illumination. • Monitor ID bit termination N 1 2 3 4 5 6 7 8 To set the sliding-type DIP switches, use a Tweeker or small screwdriver to slide the switch to the on/up/closed or off/down/open position. The default for all DIP switches is Off (down).
Installation and Operation, cont’d Up — The interface outputs serration pulses in the vertical sync interval. Down — The interface does not output serration pulses. 4 — Vertical sync pulse width — For some digital displays, if: • no picture appears, • the picture cuts in and out, • the picture is scrambled, try adjusting the output vertical sync pulse width or switching from ADSP to DDSP. Up — The vertical sync pulse is narrow. Down — The vertical sync pulse is wide.
g Remote connector — Connect an RS-232 device to this DB 9 female connector (figure 2-9) for remote centering control. Software for RS-232 control is included with the interface. See chapter 3, Remote Control for details.
Installation and Operation, cont’d Operation Connect power cords and turn on the display and audio output devices (projectors, monitors, speakers), the interface, and the input device (computer). The system is ready for operation. The image should now appear on screen, and sound should be audible. If not, ensure that all devices are plugged in and receiving power. Check the cabling and switch settings, and make adjustments as needed. If problems persist, see Troubleshooting in this chapter.
• b At the maximum level setting (the clockwise limit of this control), the interface outputs video at 1.45 volts p-p. Select a setting in the boost range (0.7 volts and above), to compensate for the decrease in signal level that occurs when the signal passes through long cables. Set the boost at 100% (the maximum level) for cable lengths over 500 feet for all computer signals of 15 kHz to 150 kHz. Peaking (Peak) control — Peaking affects the sharpness of a picture.
Installation and Operation, cont’d N The centering controls have no mechanical limits to rotation. When the minimum or maximum limit of the control is reached, LCD indicates the horizontal or vertical shift limit has been reached and the picture stops moving on the screen. Centering memory Turning the centering knobs not only moves the images, but it also stores the horizontal and vertical centering setting in the interface’s memory.
When a centering control reaches its minimum or maximum limit, the LCD displays MIN or MAX on the line below H-SHIFT or V-SHIFT. Once the centering controls are no longer active, the centering settings are saved, and the LCD displays the current scan rates. If DIP switch 1 (DDSP) on the rear panel is set to On (right) and a centering control is rotated, the LCD displays N/A DDSP ON, and the image does not shift on screen.
Installation and Operation, cont’d 4. If the picture “hangs off” the edges of the screen, adjust the centering controls ([,{). 5. If the edges of the image seem to exceed their boundaries or if thin lines and sharp edges look thick and fuzzy, try changing the Level/Boost or Peak Control settings. If the image is too bright, decrease the boost or peaking level. 6. If the image still does not display correctly, call the Extron S3 Sales & Technical Support Hotline.
