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
(525 lines/frame at 60 Hz vertical, 15.734
kHz horizontal).
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 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-pin mini-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

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

Figure 4 — VSC 75 rear panel

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.
