DVS 100 and DVS 150 1 Chapter One Introduction About the Scaler Features
Introduction Introduction, cont’d About the Scaler Each DVS 100 and DVS 150 digital video scaler allows analog video signals (composite video, S-video, and component video) to be displayed on a device with a fixed resolution and aspect ratio, such as an LCD (liquid crystal display) projector, DLP (digital light processing) projector, or plasma display. DVS 150 includes a 15-pin HD RGB pass-through connector for RGB input. Video signals coming into the scaler from this connector are not scaled.
• Output resolutions — Supports the following output resolutions: • 640 x 480 (VGA) at 60 or 75 Hz (Hertz) • 800 x 600 (SVGA) at 60 or 75 Hz • 832 x 624 (Macintosh) at 60 or 75 Hz • 848 x 480 (plasma) at 60 Hz • 852 x 480 (plasma) at 60 or 75 Hz • 1024 x 768 (XGA) at 60 or 75 Hz • 1280 x 768 (plasma) at 56 Hz • 1280 x 1024 (SXGA) at 60 Hz • 1360 x 765 (plasma) at 60 Hz • 480p (HDTV) • 720p (HDTV) • 1080p (HDTV) • Power supply — Includes an internal, 100-240VAC, 50/60 Hz, autoswitchab

Installation Overview To install and set up the DVS 100 or DVS 150, follow these basic steps: 1 If desired, mount the scaler in a rack (see “Mounting the scaler” below). Otherwise, install the rubber feet (see “Installing the rubber feet” on page 2-4). 2 Turn off power to the input and output devices, and unplug the power cables from them. 3 Attach the scaler to the input devices and the output devices. See “Cabling” on page 2-5.

Install the rubber feet only if you are not rack mounting the scaler. To install the rubber feet, do the following: 1.
Cabling The scaler can connect to input devices that produce composite video, S-video, or component video, and to output devices, such as LCD projectors, DLP displays, or plasma displays. The DVS 150 can also connect to input devices that produce RGB video via the RGB passthrough connector. To cable the scaler, complete the following steps. Use figure 5 as a general guide. DVS 100 100-240V 0.
Installation, cont’d If you cable the scaler for sync on green (RGsB or SOG) output, you must also configure the scaler for SOG via the configuration menu. See “Configuring the Scaler” on page 2-7 for instructions. You can install and run two output devices simultaneously, one using BNC connectors, and the other using the RGB connector.
7 Contrast control button — Allows you to adjust the image contrast. For more information, see “Adjusting an image” on page 3-2. 8 Horizontal shift control button — Allows you to adjust the horizontal shift. For more information, see “Adjusting an image” on page 3-2. 9 Vertical shift control button — Allows you to adjust the vertical shift. For more information, see “Adjusting an image” on page 3-2. 10 Output rate control button — Allows you to choose the output rate.
Installation, cont’d Vertical sync polarity (V-SYNC) — Changes the polarity of the vertical sync signal to allow any projector to distinguish the DVS 100 input from a standard RGB input. To toggle between Positive and Negative, turn the adjustment knob while the Vertical sync menu is displayed. By default, the vertical sync polarity is set to Negative. Sync on green (SOG) — If set to Yes, provides sync on green (RGsB or SOG) output.
DVS 100 and DVS 150 3 Chapter Three Operation Front Panel Operations
Operation Operation, cont’d Front Panel Operations The front panel includes an LCD screen that displays the current status of the scaler and the scan rate of the current video input signal. You can also use controls on the front panel to control the image display. Diagrams of the front panels are shown on page 2-6. Default screens By default, the LCD toggles between two screens every four seconds.
press the same button again or if you stop turning the knob for eight seconds. If an image control reaches its minimum, maximum, or default level, the LCD displays a screen similar to the screens shown in figure 13. COLOR Min COLOR Default COLOR Max Figure 13 — Minimum, maximum, and default value screens If input 4 (RGB pass-through) of the DVS 150 is selected, you cannot adjust the image through the scaler. Color control button — Adjusts the color intensity.
Operation, cont’d Freeze mode Freeze mode locks the output display to the current image. Freeze mode can be activated only by issuing an RS-232 command IMAGE (see chapter 4 for more information). If freeze mode FROZEN is activated, the LCD screen displays the message displayed at the left. If input 4 (RGB pass-through) of the DVS 150 is selected, you cannot activate freeze mode.
System reset To perform a system reset, press and hold the input selection button while attaching the AC power cord. The picture SYSTEM control settings for all input sources, the output rates, RESET and the configuration options are reset to their factory default settings. The LCD displays the message at the left for four seconds, and then changes back to the default screens.

Serial Communication Serial Communication, cont’d The scaler’s RS-232 connector can be connected to the serial port output of a host device such as a computer or control system. This connection makes software control of the scaler possible. Figure 14 shows a scaler RS-232 connection to a host serial port connector.
RS-232 Programmer’s Guide DVS initiated messages When a local event occurs, such as a front panel operation, the scaler responds by sending a message to the host. The DVS-initiated messages are listed below (underlined). (C) Copyright 1999, Extron Electronics, DVS xxx, Vx.x The copyright message is initiated by the scaler when it is first powered on. DVS xxx is the scaler model, and Vx.xx is the firmware version number.

Reference Information, cont’d Scaling — Changes the size of an image without changing its shape. Scaling can be used when the image size does not fit the display device. A digital video scaler converts an NTSC, PAL, or SECAM image to a size that can be displayed on a device with a fixed resolution and aspect ratio, such as an LCD (liquid crystal display) projectors, DLP (digital light processing) projectors, or plasma projector .
