Switcher Series • User’s Manual
Multiple Switcher Applications
The features of the System 4
xi
can be further expanded by connecting the output
from another switcher to Input #4. The System 4
xi
then functions as the “master”,
communicating with the projector and providing it with a signal improved by any
of the features described in this section and, if required, can even control the
connected projector using their IR (Infra-Red) remote control, RS-232 control, or
the built-in LCD menu-driven System 4
xi
front panel control.
Picture Control Memory
All inputs, including those in multiple switcher applications, have a separate
memory block for all picture controls of video or RGB and audio signals. When a
different video input is selected, the picture controls are updated automatically
from the information stored in the Picture Control Memory. RGB inputs in pass-
through mode have no stored picture control information.
Internal Power Supply with Automatic Switching
The System 4
xi
is equipped with an internal auto-switching power supply that
operates from any input voltage in the 100-240 VAC range, at 50/60Hz.
Universal Projector Control
The E
XTRON
System 4
xi
and the projector operate as a system that can be
controlled several ways:
•
through existing projector controls
•
through the System 4
xi
panel
•
through a host system using the RS-232 port
•
using Extron’s Windows® Control software
Using the projector-brand remote control, the System 4
xi
can be made to control
the following operations:
•
switch inputs
•
control projector power
•
mute the audio or video signals
•
switch input memory blocks (in projector) for convergence
•
setup saved configurations within the connected projector by input selection
•
monitor the projector for update changes, feature changes, or input selection
changes by the user
The above operations can also be accomplished by using the System 4
xi
front
panel controls or through a PC or other control system. The System 4
xi
switcher
will communicate with the projector and pass it the desired command.
When a projector manufacturer introduces a new model, the System 4
xi
can be
upgraded to accommodate it by a simple EPROM change (free during the
warranty period of two years). When a totally new projector brand and model is
introduced, Extron will either add it to the compatibility list for EPROM upgrades,
or make it an available “standard” with all future System 4
xi
switchers. Call
Extron with details of your requirements.
The unique control features of the System 4
xi
make using its switcher functions
exactly the same as using the projector-brand switcher, but with a 300 MHz
bandwidth performance — nearly three times that of most projector- brand
switchers.
_______ Some projector IR remotes do not communicate with the System 4
xi
. Also, all
projectors have different methods for source and memory recall of source inputs.
Please refer to your specific installation instructions for further details.
