DESCRIPTION  
FEATURES (CONT.)  
The Extron VSC 900 and VSC 900D two input high-resolution,  
computer-to-video scan converters combine superior processing with  
an advanced feature set, including both BNC RGB and 15-pin HD  
inputs with loop-through outputs for easy integration. In addition, the  
VSC 900D offers an SDI digital output.  
I Vertical (flicker) filtering – The VSC 900 and 900D have four  
vertical (flicker) filter settings selectable through the front panel  
LCD navigation menus. Vertical (flicker) filtering provides line  
averaging so that before the scan converter eliminates lines in the  
down conversion process, it fills in missing information. By filling  
in averaged information, the scan converter helps to maintain  
vertical detail and eliminate picture flicker.  
I Freeze button – The input of the VSC 900 and VSC 900D can be  
frozen using the freeze button on the front panel or RS-232. 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.  
I Genlock – A necessary feature for broadcast or production  
environments, genlocking is the process of synchronizing all video  
devices for the purpose of pixel switching and chroma keying of  
computer overlays. A specific type of genlocking, known as  
chroma lock, refers to the synchronization of the sync signals and  
chroma. This allows the signals to be edited and composed to  
make a complete segment without any kind of distortion, glitch,  
or signal irregularity.  
The VSC 900 and VSC 900D accept computer images at resolutions up  
to 1600 x 1200 and output a scan converted signal as composite  
video, S-video, component video, and/or RGB video. Both models are  
designed to be integrated into high-end broadcast facilities and other  
demanding production, training and presentation environments as they  
offer exceptional output quality, the ability to genlock to an external  
blackburst signal and optional SDI output. Other applications include  
videoconferencing, video recording, and viewing images on an NTSC  
or PAL monitor or other display device.  
FEATURES  
I Internal test pattern generator – The VSC 900 and VSC 900D  
offer four test patterns for quick and easy monitor set-up:  
Color Bars, 32x32 crosshatch, 4x4 crosshatch, and gray scale.  
I RS-232/RS-422 remote control – A rear panel RS-232/RS-422  
control port provides easy operation of the VSC 900 scan  
converters utilizing Extron’s Simple Instruction Set (SIS™) of basic  
ASCII code.  
I Downloadable firmware – Updated firmware can be  
conveniently downloaded from the Extron Web site. Changes to  
features and capabilities can be easily upgraded through the  
RS-232/RS-422 port.  
I Executive Mode – Ideal for unsecured environments, executive  
mode enables the user to lock out all front panel functions except  
for centering controls; all other functions remain active through  
RS-232/RS-422.  
I Flexible mounting options – The VSC 900 models are housed in  
1U high, half rack width metal enclosures that can be mounted  
under or through a desk or in a rack.  
I International internal power supply – The 100-240VAC,  
50/60 Hz, auto-switchable, internal power supply provides  
worldwide power compatibility.  
I VSC Remote – The included Extron VSC Remote provides infrared  
remote control for the VSC scan converters. It performs most  
front panel functions such as image freeze, zoom in and out, size  
and shift both horizontally and vertically, adjust the vertical filters,  
and set presets.  
I Autoscanning – Automatically recognizes and converts the  
incoming computer image, up to 1600 x 1200 resolution,  
100 kHz horizontal, and 120 Hz vertical scan rates.  
I Integration-friendly inputs – Input one is on female BNC  
connectors, eliminating the need for adapter cables and offering  
the proven reliability of BNC connections. A second input is  
offered on a 15-pin HD female VGA connector. Adapters are  
available for MAC inputs.  
I Buffered loop-throughs – Provides for local monitor outputs on  
both BNC connectors and a 15-pin HD female VGA connector,  
enabling a signal to be easily monitored or distributed without  
using a distribution amplifier.  
I Auto–Imagesetup – A press of a button automatically adjusts  
the sizing, centering, and filtering to optimize the output image.  
This can save an enormous amount of time and effort in fine-  
tuning displayed images.  
I Three simultaneous outputs – NTSC or PAL video is output as  
RGBHV, RGBS, RGsB, or component video, S-video, and  
composite video.  
I Optional SDI output (VSC 900D only) – A digital 4:2:2 output is  
available for incorporating digital video devices into environments  
such as video production studios, non-linear editing suites,  
staging events, and video broadcast studios.  
I Chroma attenuation – Chroma attenuation is an ideal feature for  
broadcast environments where colors in logos and images must  
be set at 75% saturation for transmission. The VSC 900 and VSC  
900D have the ability to attenuate an input signal down to the  
correct output level, eliminating the need to recreate the image  
and/or content.  
I Input memory presets – Allow the scan converter to  
automatically recall up to 16 user presets, 60 factory presets, and  
eight zoom presets, accessible via RS-232 or the included IR  
remote. Each memory location stores filter, size, centering, and/or  
zoom settings for a source that can be instantaneously recalled  
during a presentation.  
I High quality zooming and panning – The VSC 900 models  
feature variable zoom up to 200% and allow panning across the  
screen. User-friendly positioning, including centering and sizing,  
is accessible through the front panel for quick and efficient image  
setup.  
I Horizontal filtering – There are eight horizontal filters selectable  
through the front panel LCD navigation menus to enhance and  
stabilize the final scan rate converted video image. Horizontal  
filtering prevents anti-aliasing or pixel elimination so that less  
detail is dropped when the television scans from left to right.
