Input presets (on input 4 only) save input configuration, picture control, and OSD (on-screen display) text. Auto image™ — Auto image automatically sizes, centers, and optimizes the image to that of the scaled output rate, filling the window with the image. IP Link® — IP Link-enabled products offer an integrated Web server with high performance architecture, global compatibility with industry standard Ethernet communication protocols, multi-user support, and a Web-based asset management application specifically designed to work with products that include IP Link technology. Buffered video outputs — Five rear-panel BNC connectors and one VGA-type 15-pin HD connector provide connections for RGB or Y, R-Y, B-Y output. Both outputs (the BNCs and 15-pin HD connector) are active at all times for simultaneous output. Device control — The scaler has four methods of control; by the scaler’s front panel, via a computer or other RS-232 control device, using the optional IR 902 remote control, or via Signal Enhancements Windows Control Program. Scaled outputs — The DVS 304 offers 62 different output rates. RS-232 configuration — The DVS 304 can be configured by using the Extron control software for Windows or by using a third party control system. Front panel security lockout (executive mode) — To prevent accidental changes to the unit’s settings, the DVS 304 provides front panel lockout of all controls except input switching. 3:2 pull down detection for NTSC and 2:2 film detection for PAL video sources — These patented, advanced film mode processing features, help maximize image detail and sharpness for video sources that originated from film. When film is converted to NTSC video, the film frame rate has to be matched to the video frame rate in a process called 3:2 pull down. “Jaggies” and other image artifacts can result if conventional de-interlacing techniques are used on film-source video. The DVS 304’s advanced film mode processing recognizes signals that originated from film. The DVS 304 then applies video processing algorithms that optimize the conversion of video that was made with the 3:2 pull down process. This results in richly detailed images with sharply defined lines. A similar process is used for PAL film-source video. Versatile mounting options — The DVS 304 and DVS 304 D are 1U high, half rack wide rack mountable devices. Alternatively, they can be placed on a table or other furniture. Rubber feet and rack mounting hardware are included. The 1U high and full rack DVS 304 A and DVS 304 AD (audio models) can be rack mounted using included rack/through-desk mounting brackets. DVS 304 • Introduction 1-3 Introduction, cont’d Options and accessories The DVS 304’s optional equipment includes: • IR 902 remote control — Extron’s IR 902 (part #70-495-01) is an infrared remote control which replicates most of the front panel controls of the DVS 304 (except the Menu and Next buttons). • SDI input card — Serial digital interface (SDI) input can be added to the DVS 304 model by the installation of an SDI input card (part #70-168-01). 1-4 DVS 304 • Introduction DVS 304 2 Chapter Two Installation and Operation Mounting the Scaler Rear Panel Features Front Panel Features Menus, Configuration, and Adjustments Resetting an Input Resetting the Unit System Reset Front Panel Lockout (Executive Mode) IR 902 Infrared Remote Control Setting up the DVS to work with a Matrix Switcher Installation and Operation Mounting the Scaler The DVS 304 is 1U high, half rack wide, and is rack mountable. Alternatively, it can be placed on a table or other furniture. Rubber feet and rack mounting hardware are included. The 1U high and full rack DVS 304 A (audio model) can be rack mounted using included rack/through-desk mounting brackets. Tabletop/desktop placement Four self-adhesive rubber feet are included with the DVS 304. For tabletop use, attach one foot to each corner of the bottom side of the unit and place the unit in the desired location. UL guidelines for rack mounted devices The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the DVS in a rack. 1. Elevated operating ambient temperature — If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature. Therefore, install the DVS 304 in an environment compatible with the maximum ambient temperature (Tma = +122 °F, +50 °C) specified by Extron. 2. Reduced air flow — Install the equipment in a rack so that the amount of air flow required for safe operation of the equipment is not compromised. 3. Mechanical loading — Mount the equipment in the rack so that a hazardous condition is not achieved due to uneven mechanical loading. 4. Circuit overloading — Connect the equipment to the supply circuit and consider the effect that circuit overloading might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings sh...
