8Min/Max LED — This lights red when the minimum or maximum limit of a control (6) has been reached.

Rear Panel Features

ON — The output is in PAL (Phase Alternate Line) format (625 lines/frame at 50 Hz vertical, 15.625 kHz horizontal).

OFF — The output is in NTSC (National Television Standards Committee) format

1AC power input connector — Connect a standard IEC AC power cord here for power input (100VAC to 240VAC, 50/60 Hz).

2VGA computer input/Macintosh local monitor output connector — Connect a VGA-type computer to the VSC 75 via this 15-pin D connector (and the provided Mac-VGA cable) to use a VGA-type computer as the video signal source.

If a Macintosh, instead of a VGA-type PC, is used as a source, this connector serves as the Mac local monitor pass-through output connector.

3Macintosh (Mac) input/VGA local monitor output connector — Connect a Macintosh computer to the VSC 75 via this 15-pin HD connector (and the provided Mac-VGA cable) to use a Mac as the video signal source.

If a VGA/SVGA-type computer, instead of a Macintosh, is used as a source, this connector serves as the VGA local monitor pass-through output connector.

4DIP switches — These two switches select the signal standard (NTSC or PAL) applied to the scan converted video output, and the video input termination (75 ohm or high impedance).

1— PAL Out — Select the output standard with this switch. This switch affects both of the display outputs (composite video and S-video), but not the local monitor.

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

OFF — The VSC 75 provides high Z (high impedance) video input termination. Use this setting when the system includes a local monitor.

5S-video output connector — This 4-pinmini-DIN connector is for S-video output.

6Composite video (Video) output connector — Composite video output is continuously available on this BNC connector.

7RS-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, “Serial Communication” for details.

Cabling

Attach cables to the scan converter as detailed in the steps below. Figure 6 on page 2-9 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 75’s rear panel.
2.	Using the included Mac-VGA cable, connect the
	computer’s video output to the other input connector.

See figure 5 and the pin assignment information on page 2-9.

• If the source computer is a Macintosh, plug the VGA (15-pin HD) end into the VSC 75, and plug
