INTRODUCTION
,:'GENERAL
Congratulations! You
now
own
the industry's first
and
only Universal Projector Controller/Switcher.
Although your system switcher has been factory preset with your requested projector
brand
software configu-
ration,
it
may easily be changed to make your system switcher compatible with any projector brand you
choose.
In
the past, system switching could only be accomplished using each individual projector
manufacturer's switcher/controller,
but
now Extron's system switcher gives you an option---universality.
This
user's manual has been written with the basic user
in
mind. Itwill tell you everything
you
need to
know
to connect your system switcher to any digitally controlled projector in the market today.
If
you have
a problem, please contact
our
Technical Support experts at (714) 491-1500.
EQUIPMENT DESCRIPTION
The
Extron System 8
and
System 10 switchers are digitally controlled eight or ten
input
switchers that are
ide~!Y suited for
both
rental
and
permanent installations. Any
of
its inputs can be either RGB with separate
;,.
H;oiizontal/Vertical sync, Composite Sync, Sync
on
Green, Composite Video or S-Video.
The
switchers also
· have,uight
and
left audio follow video, with an attenuation level control, for any
of
the previously mentioned
input
formats
or
on
BNC
connectors (composite video
and
S-Video only).
The
built-in microprocessor
provides for digital control
of
all major graphics projectors.
The
system switcher can also be remotely
controlled through its manual remote connection or its RS-232 connector.
To
address large installations
with
more than 10 inputs, the switchers can be looped for up to a total
of
154 inputs (17 switchers). Fea-
tures like Video Loop Back (VLB) make this switcher adaptable for even the most demanding environments.
CONFIGURATIONS
The
System
8/10
Universal Projector Controller/Switchers are supplied in two ~onfigurations,
both
of
which can be factory preset to control any type
or
brand
of
graphics projector.

UNIVERSAL
INPUTS
Each
input
consists
of
five
BNC
video/sync connectors
and
one captive screw audio connector. These inputs
can accommodate any combination
ofRGBS,
RGsB, RGBHV, Monochrome Composite,
NTSC
(PAL),
or
1
_S-Video.
Audio can also be
input
on
any type
of
input
signal (RGB or Video) using either the
BNC
or
Phoenix
brand
captive screw terminal connectors; allowing for balanced
or
unbalanced audio. This innova-
tive universal
input
style eliminates
the
need for multiple types
of
input
modules, which results
in
lower
costs, higher performance,
and
maximum
versatility.
The
input
configuration can be changed from RGB
to
Video (or any combination)
in
a matter
of
seconds
with
no additional components required. An audio level
control
is
located
on
each
input
in
order to allow the user to balance the audio signal level.
The
System Switchers are compatible
with
all major
brands
of
digital control projectors
on
the market
including:
Ampro
Barco
Electro
home
GE/NEC
Hughesl]VC

FEATURES
(continued)>-,
-~The
switchers are factory preset for the projector brand
of
your choice
and
can easily be reconfigured in the
field for any other compatible brand in a matter
of
minutes
by
changinga few dip-switches
on
the switcher's
communications board.
'OUTPUTS
All
outputs
from the switcher are in the same format
as
the selected input.
The
switcher has separate outputs
for RGB
and
Sync, Video, S-Video, and Audio, all
of
which
must
be
run
to the projector (ifall are actually
being used). Thus, whenever an
input
is
selected, the projector always receives the proper video signal
format from the switcher.
VIDEO LOOP BACK
{VLB)
This
unique feature allows
the
switcher to integrate
with
either composite-to-RGB decoders or scan doublers.
When
the feature
is
enabled, the Composite or S-Video
output
of
the switcher can be routed through a
de~oder or scan doubler
and
back into the switcher (input
No.8
for System 8
or
input
No.IO for System 10)
,a~_arlJlGB input.
The
benefits
of
this feature include having to use only one decoder or scan doubler for all
-th~
v:i4eo
inputs rather
than
using one unit for each video source.
300
MHz
BANDWIDTH
The
highest bandwidth ever offered in a video/data switcher allows any
and
all signals to be passed through
with
no loss
of
resolution.
This
wide bandwidth
is
extremely important when using high resolution com-
puter
workstations such
~s
Sun, Silicon Graphics, Apollo, and others.
SWITCHER CONTROL
Each channel
of
the switcher can be controlled in any one
of
the following ways:
• Front Panel Buttons. Professional quality backlit push buttons that can be removed to label each
input
source.
• Remote Control Connector. Contact closure remote control connector for hard~wired remote control
with
tally indication.
• RS-232 Control Connector. Provides for computer control
of
switcher or use
of
3rd
party remote
control system.
• Infrared Remote. Projector
IR
(or hard-wired) remote will control switcher via projector. Use the
remote control included with your projector
(IR
or
hard-wired) to control Extron system switchers.

Each
input
of
the System 8/10 has a set
of
five
BNC
connectors mounted vertically. A green
LED indicator above each set
of
connectors
lights when that input
is
selected. Only one
input
can be selected at a time.

When
the the System 8/10
is
used to switch different types
of
signals, it
is
important to note that the output
signal will have the
save
format
as
the selected input.
That
is,
RGB and Sync (composite or separate H&V)
will exit through the RGB and Sync output. Likewise,
NTSC
and PAL video signals
pass
through the
Composite Video output. Therefore,
if
multiple signal types are used in the same switcher, the same mul-
tiple outputs must be used by the projector or display monitor.
. -'
.,
VIDEO LOOP BACK
(YLB)
When
using a third-party scan-doubler (line-doubler) or Composite/S-Video-to-RGB decoder, the System
8/
10 features VLB.
VLB
allows the use
of
a single scan-doubler or decoder with multiple switcher inputs to be
looped back through the System 8/10 and then output
as
RGB Sync along with
all
other RGB Sync inputs.
These video configurations are described in detail later in this section.

Connections.
. All video input connections to the System 8/10 are made with
BNC
connectors. Many types
of
video
·•
,:
1
devices (VCR, laserdisc players, etc.), including most computers, do
not
have
BNC
video output connec-
. tors.
If
not, a
suit~bl:e
adaptersuch
as
an Extron RGB 300 interface should be used to adapt the device
output to the
BNC
input
of
the System 8/10.
With
the proper adapter, the RGB/S signal can be connected
·directly to the
R,
G,
B,
H,
V inputs
of
the switcher.
If
the RGB signal
is
carrying the composite sync on
the
green channel, simply connect the RGB cables
to
the switcher without using the sync channels.
INPUT SELECTION SWITCHES
Each input must have a corresponding video mode. This
is
done by setting the
DIP
switches located above
the output connectors. There are two banks
of
DIP
switches, each having 8 (or 10) switches. Each input
has two switches, one in each bank. For example, input
#1
uses
the left most switch at each bank. For the
video mode shown
on
this page (RGBS/HVAnalog), the No.I
DIP
switch
of
each switch bankshould be
DOWN
in the RGBS position.
