DVS 150 1 Chapter One Introduction About the Scaler Features
Introduction, cont’d Introduction About the Scaler Extron’s 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. The 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.
• Power supply — Includes an internal, 100-240VAC, 50/60 Hz, auto-switchable power supply. • Precise image processing — Provides the latest in motion compensation, which produces motion images that are free of jaggies; a three-line adaptive comb filter, which eliminates chroma crawl; and a quad standard decoder, which ensures compatibility with NTSC (National Television Standards Committee) 3.58, NTSC 4.43, SECAM (sequential couleur avec mémoire), and PAL (phase alternate line) video standards.

6 Use the LCD menu screens to configure the scaler. See “Configuring the Scaler” on page 2-6. 7 The image from the input device should appear on the output device. If it does not, double check steps 3 and 4 and make adjustments as needed, and then see “Operating Problems” on page 5-2. Mounting the scaler Each DVS 150 ships with four uninstalled rubber feet. If you are going to rack mount the unit, do so before cabling it, and do not install the rubber feet.
Installation, cont’d Place the rubber foot on one corner of the scaler, and press it into place. 3. Position the rubber foot carefully before pressing it into place. It is difficult to move the foot after it is in place. 4. Repeat steps 2 and 3 to install a rubber foot on each of the remaining corners of the scaler. 5. Turn the scaler right side up and place it in the desired location.
You can install and run two output devices simultaneously, one using BNC connectors, and the other using the RGB connector.

Installation, cont’d Configuring the Scaler The LCD on the front panel of the scaler provides access to a menu that allows you to configure the scaler. • To access the menu, press the input button and the rate button simultaneously, and hold them for two seconds. The Autoswitch menu appears in the LCD. • To step through the menus, press the input button. • To exit the menu, step through the menus until the Detail menu appears, and then press the input button one more time.
VCR mode — Can eliminate horizontal noise if it is seen in a VCR image. To toggle between On and Off, turn the adjustment knob while the VCR mode menu is displayed. By default, VCR mode is set to Off. Blue mode — Turns off the red and green video output to allow you to set up color and tint using a color bar pattern. To toggle between On and Off, turn the adjustment knob while the Blue mode menu is displayed. By default, blue mode is set to Off.

DVS 150 3 Chapter Three Operation Front Panel Operation
Operation, cont’d Operation Front Panel Operation 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. A diagrams of the front panel is shown on page 2-5. Default screens By default, the LCD toggles between two screens every four seconds.
2. Turn the adjustment knob until the desired adjustment is accomplished. The LCD returns to the default screens, and the adjusted value is saved for future use by the active input, if you 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 9.
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 (see chapter 4 for IMAGE FROZEN more information). If freeze mode is activated, the LCD screen displays the message displayed at the left. If input 4 (RGB pass-through) is selected, you cannot activate freeze mode.
DVS 150 4 Chapter Four Serial Communication RS-232 Programmer’s Guide Remote Contact Closure Operation Control Software for Windows
Serial Communication, cont’d Serial Communication 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 10 shows a scaler RS-232 connection to a host serial port connector.
DVS error response When the scaler receives an SIS command and determines that it is valid, it performs the command and sends a response back to the host device. If the scaler is unable to perform the command because the command is invalid or contains invalid parameters, the scaler returns an error response to the host.
