Chapter 1 • Introduction and Features
_______ Some projector IR remotes do not communicate with the System 4 xi . Also, all
1-3
Multiple Switcher Applications
The features of the System 4xi can be further expanded by connecting the output
from another switcher to Input #4. The System 4xi 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 4xi 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 4xi 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 System 4xi and the projector operate as a system that can be
XTRON
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 4xi 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 4xi front
panel controls or through a PC or other control system. The System 4xi switcher
will communicate with the projector and pass it the desired command.
When a projector manufacturer introduces a new model, the System 4xi 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 4xi switchers. Call
Extron with details of your requirements.
The unique control features of the System 4xi 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.
projectors have different methods for source and memory recall of source inputs.
Please refer to your specific installation instructions for further details.
