System Requirements

The iScan Pro is designed to interface to
31.5 kHz progressively scanned display
devices such as:
• Data projectors
• Home Theater video projectors (31.5 kHz
scan rate required)
• HDTVs
• Progressive scan and Multimedia TVs
• Plasma TVs
• Computer monitors
If you are not sure whether or not your dis-
play will work with the iScan Pro, contact
your dealer or check the compatibility list on
our website at www.siimage.com.
The iScan Pro accepts NTSC, PAL and
SECAM video sources on any one of its
input connectors.

Inputs
There are three available inputs on the
iScan Pro:
Input 1: Composite Video
Input 2: S-Video
Input 3: Component Video (YPbPr)
We recommend using the component video
input for a DVD player and the S-Video input
for satellite receivers and/or digital cable
box. For VCRs or laserdisc players, chances
are good that using the composite video
input will give you a better picture because
the iScan Pro typically has better Y/C sepa-
ration circuitry than most of these devices.
However, you should try both composite and
S-Video to see which works better in your
system.
To connect a cable or antenna input, we rec-
ommend running that cable to a VCR and
using the composite video output from the
VCR to the iScan Pro.
Output
The iScan Pro uses a single 15-pin VGA-
style connector for its output. This is the
same type of connector most computers use
to drive computer monitors.
The VGA output connector on the iScan Pro
unit allows different configurations of cables.
For progressive scan TVs/monitors/
projectors with VGA input:
A high quality VGA-to-
VGA computer monitor
cable should be used
to connect the iScan
Pro's output to devices
that can accept progressive signals through
a VGA connector.
For progressive scan TVs/monitors/
projectors with BNC input connectors:
Many high-end TVs,
monitors and CRT pro-
jectors have BNC input
connectors. There are
usually either 3, 4 or 5
BNC connectors
depending on how
your display device
handles synchronization signals. These con-
nectors are most commonly used for RGB
but are sometimes used for Component
(YPbPr) signals as well. A standard VGA-to-
BNC breakout cable can be used to attach
the iScan Pro to any projector or television
that has BNC connectors. The connections
are shown in Table 1.
For progressive scan TVs/monitors/
projectors with component input:
The most common
plug used for
Component Video con-
nections consists of 3
RCA-type jacks. These
are the same connec-
tors that are used for
many types of audio
connections. VGA-to-
RCA cables are very
rare so we recommend
using a VGA-to-BNC
cable in combination
with a set of three BNC-to-RCA adapters.
The red, green and blue BNC connectors
should be used with the adapters and the
two remaining wires can be left unconnect-
ed. The connections are as shown in Table 1.

Power Supply

The iScan Pro comes with a universal power
supply module that accepts 100-240 VAC at
50/60 Hz. Plug the power supply into the
wall outlet and then plug the small round
connector into the "DC In" jack on the back
of the iScan Pro. Only use the power supply
that comes shipped with the iScan Pro. The
iScan Pro unit may be damaged if a power
supply that does not meet its power require-
ment is used.
To meet FCC and EMI guidelines, the iScan
Pro power supply comes with a snap-on fer-
rite collar similar to those supplied with lap-
top computers and other portable devices.
The ferrite collar should be snapped on the
end of the cable leading from the power sup-
ply to the iScan Pro as shown in the illustra-
tion below. Looping the power supply cable
twice through the ferrite and placing the fer-
rite as near the end of the cable as possible
will maximize its effectiveness.
