Introduction
About this Manual
This manual discusses how to install, configure, and operate the Extron
VSC 900/900D video scan converter and how to operate the VSC infrared remote
control (part #70-206-01).
Throughout this manual the terms “VSC”, “video scan converter”, and “scan
converter” are used interchangeably to refer to the same product.
About the VSC 900/900D
The VSC 900/900D is a two-input, high resolution computer-to-video scan
converter that accepts resolutions up to 1600 x 1200 and simultaneously outputs
NTSC/PAL composite video, S-video, component or RGB video, and SDI
component video (VSC 900D only).
The VSC 900/900D can be genlocked to an external blackburst signal for use in a
production or broadcast environment. The scan converter may also be remotely
controlled via RS-232/RS-422 Simple Instruction Set (SIS
™ ) commands or with
the optional VSC IR remote control.
Features
Autoscanning — Automatically recognizes and converts the incoming computer
image, up to 1600 x 1200 resolution, 100 kHz horizontal, and 120 Hz
vertical scan rates.
Buffered loop-throughs — Five rear-panel BNC connectors and one VGA-type
15-pin HD connector provide connections for RGB or component video
(R-Y, Y, B-Y) buffered loop-through. Both outputs (the BNCs and the 15-
pin HD connector) are active at all times for simultaneous output.
Three simultaneous outputs — NTSC or PAL video is output as RGBHV, RGBS,
RGsB, or component video, S-video, and composite video. An optional SDI
output is available (VSC 900D only) for inclusion of digital video devices.
Input memory presets — Up to 16 user presets, 60 factory presets, and eight
zoom presets, accessible via the front panel, 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.
Freeze button — The input of the VSC can be frozen by pressing this button.
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.
Auto-Image ™ setup — This feature allows for automatic adjustment of sizing,
centering, and filtering to optimize the output image.
Vertical (flicker) filtering — Four levels of vertical (flicker) filtering provide line
averaging so that vertical detail is maintained during the scan conversion
process and picture flicker is eliminated.
RS-232/RS-422 remote control — An RS-232/RS-422 control port utilizes
Extron’s Simple Instruction Set (SIS ™ ) of basic ASCII commands.
Internal test pattern generator — The VSC 900/900D offers four test patterns for
quick and easy monitor setup: color bars, 32 x 32 crosshatch, 4 x 4
crosshatch, and grayscale.
Executive mode — Enables the user to lock out all front panel functions except
for centering controls; all other functions functions remain active through
the RS-232/RS-422 port.
