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 5

What is the System 5

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 hardwired 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 http://www.extron.com.

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.

Features and Options

Features

250 MHz (-3dB) video bandwidth Five video inputs —

• 2 RGBHV/RGBS/RGsB computer video inputs — A VGA 15-pin HD front 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

control by using the Windows-based control program.

Three control methods — A computer or other RS-232 control device, the IR 401

remote control, or an SCP remote keypad can all be used to control the switcher.

RS-232 programming — The System 5 can be programmed using an RS-232

control device and SIS or Extron’s control software for Windows.

Room control — The System 5 provides a relay for controlling a variety of items

such as lighting, window coverings, or display screens.

Projector control — The System 5 can control the projector’s display power, video

mute, and mode functions.

IR command learning — The switcher can learn new IR commands from signals

received through the front panel or downloaded from Extron’s command library. Learned commands are output through the IR Emitter or IR Broadcaster.

IR Emitter — The included IR Emitter transmits learned commands and incoming

infrared control signals to devices nearby.

Memory — All IR commands are stored in memory.

Options and accessories

The System 5’s optional equipment expands a user’s ability to control system devices. Optional equipment includes:

• Display power sensor — This sensor (part #60-271-01) detects whether the projector’s power is on or off in order to keep the System 5 and the projector in sync.

• Remote control keypad — Up to two hard-wired remote keypads, such as Extron’s SCP 100P control panel (part #60-331-01, -02 or -03) can be connected via rear panel auxiliary ports. This accessory not only duplicates the functions of the System 5’s front panel, it also receives IR signals from the IR 401 and transmits them to the System 5.

• IR broadcast device — A device such as Extron’s IR Broadcaster (part #60-272-01) has a greater range than the IR Emitter and transmits signals over a wide area.

Mounting the Switcher

The System 5cr Plus comes with two sets of mounting brackets. One set is for mounting the switcher under a table or on (against) a wall, and the other set is for rack-mounting.

Table/wall mounting

The table/wall-mounting brackets extend approximately 1/4” (6.3 mm) above the top surface of the System 5 enclosure, as shown below. This design allows for an air space between the enclosure and the surface on which it is mounted. Attach the table/wall-mounting brackets to the switcher with the provided machine screws, as shown below.

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.

Display power (Power) button and LED — Once the System 5 has been

programmed with the commands for the specific projector, pressing this button toggles the projector’s power on or off.

The LED lights when projector power is on. The LED blinks quickly during projector power-up, and it blinks slowly during projector power-down. While the LED is blinking, do not send commands to the projector because the projector is not able to accept them. The blinking periods (power-up/ down delay time) are generated within the System 5, not the projector. The blinking periods can be set only via the Windows-based control program.

Display mute (Mute) button — Press this button to toggle the projector’s

“mute” function (to turn off/on the displayed image) once the Mute button has been programmed for use with the projector.

Display mode (Mode) button — This button can be programmed to switch

the mode of the projector between computer-video (RGB), S-video, and composite video. It replicates the 1-button (step) mode function provided on some projectors’ remote controls.

Input selection controls and LEDs

Use these buttons to select the appropriate input source. LEDs next to each button indicate the format of the incoming video signal. Only the selected input’s LED

lights. If the System 5 has learned commands, it may send IR commands (such as a display mode change command) to the projector when an input is selected.

PC 1 and PC 2 — Press these buttons to select input 1 (PC 1, front panel) or

input 2 (PC 2, rear panel), respectively. Both inputs accept only RGB computer-video and audio.

Input 3 — This button corresponds to Input 3 (rear panel), which can be

configured to accept audio and RGB, or S-video, or composite video. The LED corresponding to the selected format lights when Input 3 is selected.

Vid 1 and Vid 2 — Press these buttons to select input 4 (Vid 1) or input 5 (Vid 2),

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.

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 5 Communication.

Infrared control LEDs

IR function LEDs (Tx, Config, Retry) — These three LEDs indicate stand-

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 5 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 5

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 5

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.

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 5

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.

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:

Pin RS-232 function Description

2 Tx Transmit data 3 Rx Receive data 5 Gnd Signal ground

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).

DB9 Pin Locations

Female

System 5

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.

(where X1 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.

r Plus • Serial Communication4-2

Page 31

The error response codes and their descriptions are as follows: E01 – Invalid input channel number (the number is too large)

E10 – Invalid command E13 – Invalid value (the number is out of range/too large) E16 – Unit is busy E23 – Checksum error.

Using the command/response tables

The command/response tables on the next page list valid command ASCII codes, the switcher’s responses to the host, and a description of the command’s function or the results of executing the command. Lower case characters are acceptable in the command field only where indicated.

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 (

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. Run SETUP.EXE from the floppy disk.

2. 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”.

http://www.extron.com).

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;

• 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. In the System 5cr Control Program, select File, then select

Save Configuration as... .

2. 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.

3. To retrieve the configuration from within the System 5cr Control Program,

select File, then select Restore Configuration from... .

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. Follow the instructions that appear on screen.

4. 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.

System 5

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. Select Emulate instead of one of the comm ports.

3. 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. Select the File menu.

3. 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. Remove the switcher from the rack, wall, or furniture.

3. 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.

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 (

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.
