● Description
The Extron VSC 500 High Resolution Computer-to-Video Scan Converter combines high performance processing, features, and value. The VSC 500 accepts computer-video signals with resolution up to 1600 x 1200 and outputs a scan converted NTSC or PAL video signal as composite video, S-video, component video, and/or RGB video. Applications include videoconferencing, video recording, and viewing the images on a PAL or NTSC monitor or other display device. Key features include Auto-Image™ setup for automatic adjustment of centering, sizing, and filter settings; zoom control up to 200%; an LCD display for user-friendly menu navigation; memory presets; and a buffered loop-through for local monitor output. The VSC 500 can be controlled via the front panel, IR remote, or RS-232 and RS-422 serial commands.
● Features
- Autoscanning - Automatically recognizes and converts incoming computer-video signals at resolutions up to 1600 x 1200, horizontal scan rates up to 100 kHz, and vertical refresh rates up to 120 Hz.
- Input - The input is on a female 15-pin HD connector.
- Buffered loop-through - Provides for local monitor output on a female 15-pin HD connector, enabling a signal to be easily monitored or distributed without using a distribution amplifier.
- Auto-Image™ setup - A press of a button automatically adjusts the sizing, centering, and filtering to optimize the output image. This can save time and effort in fine tuning displayed images.
- Three simultaneous outputs - NTSC or PAL video is output as RGBHV, RGBS, RGsB, or component video, S-video, and composite video.
- Input memory presets - Allow the scan converter to automatically recall up to 16 user presets and 60 factory presets.
- Zoom presets - Eight zoom presets are available for recalling size, position, and filtering, accessible via the optional IR, RS-232, or RS-422. This feature enables the user to quickly zoom in on a certain area of an image.
- High quality zooming and panning - The VSC 500 features variable zoom up to 200% to allow for panning across the screen. User-friendly positioning, including centering and sizing, is accessible through the front panel for quick and efficient image setup.
- Horizontal and vertical (flicker) filtering - The VSC 500 has four vertical filter settings selectable through the front panel LCD navigation menus. Filters reduce jitter, improve image stability, and assure that minimal picture detail is dropped during scan conversion.
- Freeze button - The output video of the VSC 500 can be frozen using the freeze button on the front panel. This feature allows the scan converter to capture a frame of video to display for an extended period of time, even after the source has been removed.
- Internal color bar generator - The VSC 500 includes a color bar pattern for simplified setup of a display. The color bar pattern or a black screen can be set as the default output when no input signal is present.
- RS-232 and RS-422 control - A rear panel RS-232 and RS-422 control port provides connection to a third-party control system utilizing Extron's Simple Instruction Set (SIS™), which provides easy operation of the VSC 500 scan converter.
- Front panel security lockout - Ideal for unsecured environments, this feature enables the user to lock out all front panel functions except for centering controls; all other functions remain active through RS-232 and RS-422 control.
- Flexible mounting options - The VSC 500 is housed in a 1U, half rack width metal enclosure that can be mounted under or through a desk or in a rack.
- IR Remote - The optional Extron VSC Remote provides infrared remote control. It performs most front panel functions including image freeze, zoom, size and shift, vertical filter adjustment, and memory preset.
- Internal international power supply - The 100-240VAC, 50/60 Hz, autoswitchable internal power supply provides worldwide power compatibility.
