DUAL SYSTEM VIDEO CONVERTER
RGB/EXPANSION: This premium-
quality output, which can be used by
some video projectors and monitors,
consists of separate red, green, blue,
and sync signals. Feed the signal into
compatible equipment by using our
optional RGBS cable with BNC
connectors, European SCART
connectors, or connectors for
Sharp LCD projectors. Call Black
Box to order these cables.
3.3 Selecting Your Video Standard
Use the NTSC/PAL slide switch on
the back of your Converter to choose
which standard you’ll use for the
VIDEO, S-VIDEO, and RGB outputs.
NTSC is the video standard for the
USA, Canada, Mexico, Japan, and
parts of South America. PAL is used
throughout most of Europe, the
Middle East, Southern Asia, and
the Pacific Rim.
3.4 Final Preparations
Turn on your computer. The green
indicator labeled LOCK on the
Converter’s front panel should light,
showing that the Converter is
receiving a proper signal from the
computer. (Refer to the next chapter
for an explanation of this indicator.)
Make sure the FREEZE IMAGE
switch on the front panel is in the
NORMAL position, so that your
computer-image sequences will flow
smoothly.
