Extron electronic VSC 50 Setup, Controls and Indicators, Setting up the VSC, Rear panel cabling

Setup

The Extron VSC 50 converts computer scan rates of up to 800 x 600 to NTSC/PAL and S-video outputs. The scan converter connects between the computer and the desired output devices (monitor, VCR, or any compatible video device).

Setting up the VSC 50

To install and set up the VSC 50, follow these steps:

1 Turn off all of the equipment. Ensure that the computer video

source and the output devices are all turned off and disconnected

from the power source.

Rear panel cabling

All connectors are on the rear panel. Figure 1 and figure 2 show the cable connections on the rear panel of the VSC 50.

Input connections

1PC or Macintosh connection — Use the 6-foot VGA/Mac adapter cable (part #26-462-01) provided for connecting the VSC 50 to either a PC type or a Macintosh computer. The connector size and gender prevent making improper connections.

PC connections — Plug the VGA end of the Mac/VGA adapter cable into the computer’s video card output connector and plug the Mac end into the Mac connector on the VSC 50 rear panel (figure 1). Plug the monitor's video cable into the VGA connector on the rear panel of the VSC 50.

Mac connections — Plug the Mac end of the Mac/VGA adapter cable into the computer’s video output connector and plug the VGA end into the VGA connector on the VSC 50 (figure 2). Plug the monitor’s video cable into the Mac connector on the rear panel of the VSC 50.

Output connections

2Composite (NTSC/PAL) — This BNC connector provides either NTSC or PAL composite video, depending upon the position of the rear panel PAL Out DIP switch. This output is always available.

3S-video— This 4-pin mini-DIN connector outputs S-video. This is the highest quality video output for a VCR or a CODEC.

Power

4AC power connector — Plug a standard IEC power cord into this connector to connect the VSC 50 to a 100 to 240VAC, 50 Hz or 60 Hz power source.

Turn on the computer monitor and the computer, in that order.

5Power LED — The Power LED lights to indicate power is on. If AC voltage is available, power is on.

6Freeze button and LED — Pushing the Freeze button toggles between freeze frame or motion mode. Freeze provides a still image capture of a scan-converted computer screen. The Freeze LED indicates that the VSC 50 is in freeze frame mode. While this LED is lit, the video output is a single frame of video. Press the freeze button again to return to motion mode.

7 Centering (vertical) — This knob adjusts the vertical position (vertical shift), by shifting the image up and down on the screen.

8 Centering (horizontal) — This knob adjusts the horizontal position (horizontal shift), shifting the image left and right on the screen.

Nonvolatile memory saves the centering adjustments for the current scan rate.

9Min and Max LEDs — The Min or Max LED lights to indicate the vertical or horizontal centering adjustment has reached the minimum or maximum limit of its range.

10Over/Under switch — The Over/Under switch provides two ways to view the displayed image: the Over position provides an overscan that is 10% larger than the standard size and the Under position displays the image at its normal size.

11Flicker Filter switch — The Flicker Filter switch selects from two levels of flicker filtering. Select the position that gives the best
