2 — 75 Ohm (video input termination) — This switch provides a way to prevent blooming when no local monitor or termination adapter is connected.

ON — The VSC 150 provides 75 ohm video input termination. Select this setting when a local monitor is not used.

OFF — The VSC 150 provides high Z (high impedance) video input termination. Use this setting when the system includes a local monitor.

5Composite video (Video) output connector — Composite video output is continuously available on this BNC connector.

6S-video output connector — This 4-pinmini-DIN connector is for S-video output.

7Output selection switch — In addition to the

composite video output, one other output can also be active. Choose from the following formats via the output selection switch:

•S-video output (select S-video),

•RGBS (composite sync) output (select RGB),

•RGBHV (separate horizontal and vertical sync) (select RGB), or

•Y, R-Y, B-Y (component video) output (select R-Y/B-Y/Y).

The output cables must also be connected to the appropriate connector(s) for the second output.

Connect cables for only one output in addition to the composite video output. Do not connect cables to outputs that will not be used for your application. Connecting cables to more outputs will overload the circuits and yield weak signals.

8RGB/component video output connectors — These BNC female connectors are for RGB output (red, green, and blue video output; and horizontal, vertical, and composite sync output), or for component video output (R-Y, Y, B-Y). See “Cabling” in this chapter for details.

9Genlock connectors — A genlock (black burst generator) device can be connected to the VSC 150 via these female BNC connectors to synchronize it with other system components for seamless vertical interval

switching between sources. See “Cabling” and “Setting Up Genlock and Vertical Interval Switching” in this chapter.

10RS-232 connector — Connect a computer or RS-232 control module to this 9-pin D connector to allow remote control using the Simple Instruction Set or the Extron graphical control program for Windows. See chapter 3, “Remote Control” for details.

Cabling

Attach cables to the scan converter as detailed in the steps below. A diagram on page 2-11 shows how the system looks when cabling is finished.

1.	Connect the local monitor via its video input cable to
	the corresponding (Mac or VGA) “input” connector
	on the VSC 150’s rear panel.
2.	Using the included Mac-VGA cable, connect the
	computer’s video output to the other input connector.
	See the diagram below and the pin assignment
	information on page 2-12.

•If the source computer is a Macintosh, plug the VGA (15-pin HD) end into the VSC 150, and plug the other (15-pin D) end into the computer’s output connector.

•If the source computer is a VGA-type PC, plug the Mac (15-pin D) end into the VSC 150, and plug the other (15-pin HD) end into the computer’s output connector.
