Introduction
About this Manual
This manual discusses how to install, operate and configure the Extron
System 5cr Plus switcher and how to operate the IR 401 infrared remote control that
is included with the System 5cr Plus. For information on installing and operating
related accessories, see the user’s guides for the following products: Extron’s
Current/Display Power Sensor (part #68-391-01), IR Broadcaster (part #68-392-02),
and SCP 100P Control Pad (part #68-390-01).
Throughout this manual the terms “System 5” and “System 5cr Plus” are used
interchangeably to refer to the same product.
About the System 5cr Plus
What is the System 5cr Plus?
The System 5 switcher provides central control for small audio/video (A/V)
installations. It offers video and audio switching, room control, and projector
control. Each of these functions can be controlled by the front panel, by a hard-
wired control pad (the SCP 100P), and by infrared remote control (the IR 401). The
switcher can be used to control video and audio input settings; display functions
such as power, video mute, and video modes; and room functions, such as
lowering or raising a display screen or powering lights on or off. The System 5 also
features the ability to “learn” infrared projector control commands.
The System 5 accepts two computer-video (RGB) inputs, two composite video or
S-video inputs, and one RGB or composite video or S-video input, for a total of five
video inputs. It also accepts five line-level stereo audio inputs.
The System 5 outputs computer video (RGBHV/RGBS/RGsB), or NTSC/PAL
S-video or composite video to one display device. The System 5 also offers one line
level (line out) and one amplified stereo audio output. Rear panel ports allow
connection of the IR Emitter and/or the optional IR Broadcaster or hard-wired
projector remote control, and addition of an optional display power sensor, remote
control keypads and an RS-232 controller.
Controlling an A/V system
The System 5 and other devices can be controlled using one or more of these items:
• The front panel controls.
• A computer, a touch screen panel, or any other device that can send and receive
serial communications through the RS-232 port. Extron’s Simple Instruction
Set™ (SIS™) is a set of simple keystroke commands that can be used with
any such devices, and Extron’s control software for Windows provides a
graphical interface for controlling the switcher from a computer.
• Optional control pads (the SCP 100P) that can be mounted in a wall or podium
and hard-wired to the System 5. Each SCP 100P replicates the front panel
functions, and it can receive IR signals and pass them to the System 5.
• The IR 401 remote control, which can also perform all of the front panel
functions.
For the System 5 to control a projector, it must be programmed. The System 5 can
program itself by learning projector IR commands, or Extron’s IR library of
commands can be loaded into the System 5’s memory. The IR library and the
latest control software are available on the Extron web site at
The System 5 learns new projector control commands from infrared (IR) signals it
receives via its front panel IR ports. These commands are added to the panel
functions. When a function is selected, the System 5 transmits the learned IR signal
to the projector through the IR Emitter or the optional IR Broadcaster.

panel connector (PC 1) allows direct connection of a laptop computer, and
one set of five BNC rear panel connectors (PC 2) accepts inputs via an
interface.
1 RGBHV/RGBS/RGsB computer video or S-video or composite video
input — A set of five BNC rear panel connectors (Input 3) accepts RGB input
via an interface, or it can be configured to accept either S-video or composite
video input instead of RGB input.
2 S-video or composite video inputs — Inputs Vid 1 and Vid 2 each have
two rear-panel BNC connectors.
One video output — A total of eight rear-panel BNC connectors provide
connections for RGB, S-video, or composite video (NTSC/PAL) output. Only
one output (RGB or S-video or composite video) is active at any one time,
even if all three sets of BNCs are connected to the projector.
Five balanced/unbalanced stereo audio inputs — One front panel mini stereo jack
and four rear panel captive screw ports accept audio inputs. Each input’s
levels can be individually preset, then adjusted by the master volume control.
Two stereo audio outputs —
•
Line level (line out) output (balanced or unbalanced) via a captive screw
terminal can be treated as a pre-amp. The output can be adjusted using the
master volume control, or it can be set via RS-232 control to provide a fixed
output level.
•
Amplified output (unbalanced) of 24 watts (12 watts per channel with a
4 ohm load) or 12 watts ( 6 watts per channel with an 8 ohm load) is available
for non-powered speakers via spring-loaded captive terminals. The master
volume control adjusts the output level.
Audio breakaway — Audio and video can be switched separately via RS-232

function is active (on). See page 2-5 for information on the room/relay port,
and see page 4-7 and refer to the Windows-based System 5cr Help program
for details on changing settings.
Display function controls and LEDs
The settings of the display functions (power, mute, and mode) are customized for
each projector. These buttons function only after they have been programmed,
either by “learning” IR commands or by loading projector commands (drivers)
from the Extron IR library.

respectively. Both of these rear panel inputs can be configured to accept audio
and either S-video or composite video.
Audio breakaway (the ability to separately switch audio and video signals from
different inputs) is available only via the RS-232 control. While audio
breakaway is active, the flashing LED indicates the input providing the audio
signal, and the steadily lit LED indicates the active video input.
Audio adjustment control and LEDs
Audio indicator LEDs (Max, Clip, and Min) — These LEDs light in response
to changes made via the front panel volume control knob or RS-232 or control
software commands.

Max LED (red) – This LED lights when the volume control knob has reached
its maximum limit. It does not indicate anything about the audio level.
Clip LED (green) – This LED lights when the audio output level starts to peak
(overdrive) and the signal is clipped, often when the input level is too
high. It is used mostly during audio input attenuation setup.
Min LED (red) – This LED lights when the volume control knob has reached
its minimum limit. It does not indicate the audio level.
Volume control knob — Turn this to adjust the audio volume (audio gain) for
the amplified output. The volume control knob can be used as a master
volume control for both audio outputs if all the audio inputs have the same
level. There is no physical limit to this knob’s rotation. The Min or Max LED
will light briefly when the knob has reached its functional minimum or
maximum limit.
10
Audio gain/attenuation can be set per input via the front panel controls or via
RS-232 commands or the Windows-based control program. For details, see
Setting Up the System 5cr Plus in this chapter, and chapter 4, Serial
Communication.
Infrared control LEDs
IR function LEDs (Tx, Config, Retry) — These three LEDs indicate stand-
11
alone functions and also are used in combinations during IR learning. For
example, all three LEDs flash at once to indicate a timeout when the System 5
is in configuration mode. See Setting Up the System 5cr Plus in this chapter for
details on when the LEDs light in combination.
Transmit (Tx) LED (green) – This lights while the System 5 transmits infrared
signals.
Configure (Config) LED (amber) – This lights steadily when the
System 5 is in setup (configuration) mode.
Retry LED (red) – This lights when the System 5 does not recognize a
command during the infrared learning process.

Setting Up the System 5cr Plus
The System 5cr Plus must be set up (configured) before it can control other
equipment. Setup can be done from the front panel, or from a computer using the
provided control software. Setup cannot be done via the IR 401 remote control or
the SCP 100P control pad.
Extron provides preset configurations in the form of projector driver files that can
be downloaded from diskette or the Extron website. See “Downloading and using
projector drivers” in chapter 4 for details. Projector drivers assign projector IR
commands to the System 5’s front panel controls so that the display power, mute,
and mode functions can be used to control the projector.
Configuring the System 5cr Plus from the front panel
The System 5 must be in the setup (config) mode during setup. The Config LED
lights when the setup mode is on. The following configuration procedures can be
performed from within setup mode:
• clear an individual button’s IR function configurations,
• clear all System 5 settings,
• set audio input attenuation levels,
• select video formats,
• initiate IR learning.
See the flowcharts in this section for the specific steps for setting up the System 5.
When there has been no activity for at least 20 seconds, the System 5 times out
from the setup mode to the normal mode, and the Tx, Config, and Retry LEDs
will all flash for 5 seconds.

Initiating IR learning
The System 5 can “learn” control commands from projectors’ remote controls.
IR learning is only necessary if there is no IR driver available for that projector or if
the driver is not complete.
The System 5cr Plus has two portholes on its front panel:
•
one for the IR receiver (Rx), which receives signals
from the IR 401 remote; and
SYSTEM 5 Plus
IR
TX
CONFIG
RETRY
RX LEARN
•
one for the IR learning device (Learn), which receives
signals from a projector’s remote control during
IR learning.
During IR learning you might need to hold the projector’s IR remote control as near
to the System 5 as one-half inch and point the remote directly at the IR learning
(Learn) device. Blocking ambient light from the IR learning device, particularly
from flourescent lights, can also help.
Once the System 5 has been programmed to control the projector, do not
perform the learned projector control functions from the projector or the
projector’s remote control. The System 5 will not know that projector control
commands have been sent by an external device. For example, if a projector is
powered on via the System 5, and then the projector is manually turned off at
the projector’s panel, the System 5 will not know the projector is off, and it will
continue to send video signals and commands to the projector.

Remote Control of the System 5cr Plus
The System 5 can be controlled by using its front panel controls, the included
IR 401 infrared remote control, optional SCP remote control panels, or an
RS-232 control device or computer.
The IR 401 and SCP control panels replicate the System 5’s front panel controls for
normal mode operations. The RS-232 control device also can send front panel
normal mode commands. A computer using Extron’s Windows-based control
program can perform both normal mode and setup mode operations, and it offers
some functions that are not available with the other control methods. See chapter 4,
Serial Communication, for details.
The IR 401 uses
place of the volume knob. It also has
an audio mute button.

Serial Communication
The System 5cr Plus can be remotely controlled via a host computer or other device
(such as a control system) attached to the rear panel RS-232 connector. The control
device (host) can use either Extron’s Simple Instruction Set (SIS) commands or the
graphical control program for Windows.
The System 5 switcher uses a protocol of 9600 baud, 1 stop bit, no parity, and
no flow control.
The rear panel RS-232 9-pin D connector has the following pin assignments:

RS-232 Programmer’s Guide
Host-to-switcher communications
SIS commands consist of one or more characters per field. No special characters
are required to begin or end a command sequence. When the System 5cr Plus
determines that a command is valid, it executes the command and sends a
response to the host device. All responses from the switcher to the host end with a
carriage return and a line feed (CR/LF = ), which signals the end of the response
character string. A string is one or more characters.
Switcher-initiated messages
When a local event such as a front panel (or SCP control pad) selection or
adjustment takes place, the System 5 switcher responds by sending a message to
the host. No response is required from the host. The switcher-initiated messages
are listed here (underlined).
(C) Copyright 2000, Extron Electronics, System 5cr Plus, Vx.xx
The System 5 sends the copyright message when it first powers on. Vx.xx is the
firmware version number.
RECONFIG
When a change is made via a front panel control or another operation occurs that
must be written to a new memory block, the System 5 sends the reconfiguration
message. No response is required from the RS-232 host, but the host may request a
new status listing via the request information command (I/i). See the command/
response table in this chapter for details.
X1
X1
C
(where
is the input number)
The System 5 sends this response when an input is switched. C = both audio and
video were switched.
Error responses
When the switcher receives a valid SIS command, it executes the command and
sends a response to the host device. If the System 5 is unable to execute the
command because the command is invalid or it contains invalid parameters, it
returns an error response to the host.

Control Software for Windows
Installing the software
The included graphical control software for Windows offers another way to control
the System 5 via RS-232 connection in addition to the Simple Instruction Set
commands. The control program’s graphical interface includes the same functions
as those on the switcher’s front panel and some additional features that are only
available through the Configure Unit screen of the Windows-based software.
The control software is compatible with Windows 95/98, and Windows NT.
Extron’s System 5cr Control Program is included with the System 5, and updates
can be downloaded from the Extron website (http://www.extron.com).
The control program is contained on two 3.5-inch diskettes, and it requires
approximately 2 MB (megabytes) of hard disk space.
To install the software on the hard drive:
1.
2.
Run SETUP.EXE from the floppy disk.
Follow the instructions that appear on the screen.
By default the installation creates a C:\System5 directory, and it places two icons
(SYSTEM 5cr Control Pgm and SYSTEM 5cr Help) into a group or folder named
“Extron Electronics”.
Using the software
Using the control program
1.
To run the control program, double-click on the SYSTEM 5cr Control Pgm
icon in the Extron Electronics group or folder. The Comm menu
appears on the screen.
2.
Click on the comm port that is connected to the System 5cr Plus’ RS-232 port.
(A view-only emulation mode is also available.) The Extron SYSTEM 5cr
Control Program window appears. It displays the current settings. There are
three views available:
•
the main screen (Normal Mode; the default mode), shown below, which
allows all normal mode front panel functions;
•
•
Executive Mode screen, shown below, which allows input selection only;
and
Configure Unit screen, shown on the next page, which includes all front
panel functions plus additional configuration options that are part of the
setup (config) mode. Some operations can be done only via this part of
the Windows-based program.

Power-up/down delay, room relay mode, auto-set attenuators, RGB delay, and
miscellaneous options are adjustable only via the Configure Unit control screen.
Refer to the System 5cr Help program for details on setting these options.
Power Up/Down Delay — This feature does not control the projector in any way.
It simulates projector delays from 10 seconds to 5 minutes (adjusted in
10-second increments). For a projector that has a warm-up or cool-down cycle
during which it will not accept commands, adjust the System 5’s power-up or
power-down delay time to match that of the projector. During the delay time,
the Power LED will blink as a reminder to not send commands to the projector.
Room relay modes — Select one of the two room relay modes (latched or
momentary) to change how the room relay operates. The default is
momentary contact for 1/8 second.
•
Select Latched to require a press of the Room button to toggle the relay
on or toggle it off.
•
Select Momentary to allow the relay to automatically turn off after a set
period time, of from 1/8 second to 2 seconds. Pressing the Room button
will turn the relay on, and the relay will automatically shut off when the
period ends.
RGB delay — This is used in Triple-Action (video mute) switching. With Triple-
Action switching, the System 5 switches to the new sync signal before
switching RGB (video) signals. That allows the projector to adjust to the new
sync timing during a brief delay before displaying the new picture, which will
appear without glitches. The blanking period (RGB delay time) can be set to a
period from 0 seconds to 5 seconds (in half-second steps) via the Configure
Unit screen.
Saving and restoring configurations
The System 5 can be configured by various means (IR learning, downloading, front
panel adjustment, or combinations of those methods), and the configuration
settings can be saved to a file for later use.
1.
2.
3.
In the System 5cr Control Program, select File, then select
Save Configuration as... .
Save the file as (filename).sy5. An unlimited number of configuration files can
be saved as long as each file has a unique file name ending in .sy5.
To retrieve the configuration from within the System 5cr Control Program,
select File, then select Restore Configuration from... .

To learn how to use the help program, select Using Help from the Help menu or
press the F1 key from within the Help program.
Downloading and using projector drivers
The System 5cr Plus must be set up (configured) before it can control other
equipment. Extron provides preset configurations in the form of projector driver
files. Projector drivers assign projector IR commands to the System 5’s front panel
controls so that the display power, mute, and mode functions can be used to control
the projector.
The most recent projector driver files are available at the Extron website at
http://www.extron.com. To download files to computer, do the following:
1.
From the Extron website, select Download, then select System 5cr Projector
Drivers.
2.
Locate the model of projector for which a driver is needed, and click on the
file name of the driver used by that projector.
3.
4.
Follow the instructions that appear on screen.
If the projector driver has been successfully downloaded, the projector driver
will be displayed in the Configure Unit screen of the Windows-based control
program. It will also appear in the list of available projector drivers when
Restore Configuration from... is selected from the Windows-based control
program’s File menu.
To view the settings and commands in each projector driver file without loading
the driver into the System 5, run the System 5 control software in emulation mode.
1.
Double-click on the SYSTEM 5cr Control Pgm icon in the Extron Electronics
group or folder. The Comm menu appears on the screen.
2.
3.
Select Emulate instead of one of the comm ports.
Select and double-click on the desired projector driver in the
(drive):\System5\drivers folder. Projector driver filenames end in .5cr.
To load projector drivers into the System 5, do the following:
1.
Upon opening the control program, select and double-click on a comm port
instead of emulation mode.
2.
3.
Select the File menu.
Select Restore Configuration from... and choose the appropriate driver.

Firmware Upgrade Installation
In some cases the System 5’s firmware may require replacement with an updated
version. The two user-replaceable firmware chips are U1, the main microcontroller,
and U7, the carrier signal generator.
Changes to firmware must be performed by authorized service personnel
only.
Follow these steps to replace firmware in the System 5.
1.
Disconnect the AC power cord from the System 5 to remove power from the
unit.
To prevent electric shock, always unplug the System 5 switcher from the
AC power source before opening the enclosure.
2.
3.
Remove the switcher from the rack, wall, or furniture.
Remove the cover of the switcher (the top half of the enclosure) by removing
the screws, then lifting the cover straight up.
Do not touch any switches or other electronic components inside the
switcher. Doing so could damage the switcher. Electrostatic discharge
(ESD) can damage IC chips even though you cannot feel it. You must be
electrically grounded before proceeding with firmware replacement. A
grounding wrist strap is recommended.
4.
Locate chips U1 and U7 on the front panel circuit board, as shown below.

Locating firmware IC chips U1 and U7, and aligning the
PLCC chip puller tool with firmware chip slots
5.
After you are electrically grounded, align the hooks of a PLCC IC puller tool
with the slots located in diagonally opposite corners of the firmware chip that
you wish to upgrade.

8.
Insert the hooks into the slots, and squeeze the tool gently to grasp the chip.
Pull the chip straight out of the socket, and set it aside.
Align the slots of the new firmware IC chip with the angled corners of the
socket in the same orientation as the old chip.
9.
Gently but firmly press the chip into place in the socket.
10. If you are replacing both firmware chips, repeat steps 5 to 9 for the other chip.
11. Replace the top cover on the System 5 switcher, and fasten it with the screws
that were removed in step 3.
12. Rack mount the switcher, and reconnect the AC power cord.
Glossary
Attenuate/attenuation — To reduce the amplitude (strength) of a signal or current.
Balanced audio — A method that uses three conductors for one audio signal. They
are plus (+), minus (-), and ground. The ground conductor is strictly for
shielding, and does not carry any signal. Balanced audio is also called
“differential audio”.
Bandwidth — A frequency range, or “band” of frequencies between the limits
defined by the “half power points”, where the signal loss is -3dB. In audio
and video, it is this band of frequencies that can pass through a device
without significant loss or distortion. The wider the bandwidth, the better
the quality that results, such as a sharper picture or better sound. The higher
the bandwidth number, the better the performance. (300 MHz is better than
250 MHz.) When a signal passes through a path with more than one device
(including cables), the limiting factor (bottleneck) in that path is the device
with the narrowest bandwidth.
Breakaway — The ability to separate audio and video signals for switching them
independently. For example: the audio and video signals from one source
may “break away” and be switched to two different destinations.
Buffer — Generally referred to as a unity gain amplifier, a buffer is used to isolate
the signal source from the load. A buffer can be used for digital or analog
signals.
Clipping — Cutting off the peaks (or excursions) of a signal. A form of distortion
that occurs when the signal excursions exceed the limits of the circuit, and the
signal flattens out.
Clipping level — An electronic limit (short of the distortion point) to which audio
should be set to avoid overdriving an audio signal. Setting the clipping level
appropriately allows headroom for maintaining signal fidelity.
IR learning — The ability of a device, such as Extron’s System 5cr Plus, to receive
and store infrared commands for other devices, such as a projector. Each
command is assigned to a system operation (such as selecting an input).
When an operation is executed, the associated (learned) command is then
transmitted through an IR emitter or broadcaster to the projector, where it is
executed.
IR library — Sets of downloadable infrared commands (drivers) for video
projectors available at Extron’s web site (http://www.extron.com).

Latching — The System 5 room relay can operate in two modes: latching or
momentary. In the latching mode, the relay remains active (latched) until it is
manually reset (unlatched).
Level — The relative intensity (strength, voltage, volume) of an audio or video
signal. The output level can be changed by attenuation (a decrease relative to
the input signal) or gain (an increase in the signal level).
RGB delay — This is used in Triple-Action (video mute) Switching. With triple-
action switching, the System 5 switches to the new sync signal before
switching RGB (video) signals. That allows the projector to adjust to (lock
onto) the new sync timing during a brief delay before displaying the new
picture, which will appear without glitches.
