Introduction
About the VSC 500/700/700D
The Extron VSC 500, 700, and 700D are computer-to-video scan converters that can convert
computer images up to 1920 x 1200 for output as composite video, S-video, component
video, SDI (VSC 700D), and/or RGB video. Applications include videoconferencing, video
recording, and viewing of images on an NTSC or PAL monitor or other display device.
Key features include automatic setup of centering and sizing controls, horizontal filtering, an
LCD window for user-friendly menu selections, memory presets (IR remote control feature),
and a buffered loop-through for local monitor output. The VSCs can be controlled via the
front panel, the optional IR remote control, or RS-232 commands.
Features
• Autoscanning — Automatically recognizes and down converts the incoming computer
image, up to 1920 x 1200 resolution and 100 kHz horizontal and 120 Hz vertical scan
rates.
• Input — Via a 15-pin HD female VGA connector (VSC 500) or BNC connectors (VSC
700/700D).
•
Outputs — Simultaneously outputs RGB or component video, composite video, S-video,
and SDI (VSC 700D).
• Memory presets — Recall up to eight user presets that can be stored and accessed via
the optional IR remote.
• Auto-Image™ setup — Automatic sizing and centering function to fill the output
display screen.
• Centering and sizing and controls — Allow for user-friendly positioning and sizing of
the image on-screen.
• Freeze/Reset button — The freeze function locks the output display to the current
image.
•
Front panel security lockout — Locks out all front panel functions except centering
(shifting) to prevent accidental changes to adjustments.
• RS-232 remote control — An RS-232/RS-422 control port utilizes the Extron Simple
Instruction Set (SIS
™ ) of basic ASCII commands.
•
Genlocking (VSC 700 and VSC 700D only) — Allows for the synchronizing of multiple
input devices to a common external timing signal so that the switch between input
devices will be clean.
•
Horizontal filtering — Four selectable horizontal filters prevent aliasing or pixel
elimination so that less detail is dropped when the image is scanned from left to right.
• Buffered loop-through — Provides a local monitor output, enabling the computer
input signal to be monitored without the need for a separate distribution amplifier.
