About the System 7SC

What is the System 7SC?

The System 7SC is a seven input, configurable switcher with a built-in video scaler and projector control ability.

The System 7SC provides central control and integration for small audio/video

(A/V) installations. It offers video and audio switching, room controls, and projector control. Each of these functions can be controlled at the front panel, by a hardwired control pad, by infrared remote control (the IR 701), or via RS-232 control.

The switcher can control video and audio input settings; display functions such as power, video mute and video modes; and execute relay/room functions, such as lowering or raising display screens or powering lights on or off. The System 7SC also has the ability to “learn” infrared projector control commands.

The System 7SC accepts computer-video (RGB), component video, S-video and composite video, and each input is separately configurable. The switcher also accepts seven line-level, balanced or unbalanced stereo audio inputs.

1-2 System 7SC • Introduction

The System 7SC scales composite video, S-video, and component video up to computer-video (RGBHV/RGBS/RGsB), which can be output to two display devices via individually buffered BNC and 15-pin HD ports. The System 7SC offers one fixed level (preamp) stereo audio output and one variable level stereo audio output.

Rear panel ports allow connection of remote control keypads, the IR Emitter and/ or the optional IR Broadcaster, an optional display power sensor, hardwired projector control, and an RS-232 controller. The System 7SC also has a power port to provide power for accessories such as SCP control pads.

Controlling the switcher and an A/V system

The System 7SC 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 the 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.

• A contact closure device.

• Extron control pads, such as the SCP 250, SCP 200, or SCP/AAP A.

• The optional IR 701 remote control, which can perform all of the front panel functions.

For the System 7SC switcher to control a projector, it must be programmed. The switcher can be programmed by having it learn projector IR commands, or Extron’s

IR/RS-232 library of commands can be loaded into the switcher’s memory. The

IR/RS-232 library and the latest control software are available on the Extron Web site at http://www.extron.com.

The System 7SC learns new projector control commands from infrared (IR) signals it receives via its front panel IR port or from commands input via an RS-232 device.

These commands are stored in the switcher’s memory and assigned to the front panel control (Display Power, Display Mute, Mode, Room 1, Room 2) and input buttons. When a button is pressed, the switcher transmits the stored signals to the projector via the IR comm port or the projector control RS-232 port. The IR 701, optional control pads, and/or an RS-232 control system can also be used to execute these stored commands.

System 7SC • Introduction 1-3

Introduction, cont’d

Features and Options

Features

350 MHz (-3 dB) video bandwidth

Configurable video inputs —

• Inputs 1 to 6 — Six sets of 5 BNC connectors on the rear panel accept

RGBHV/RGBS/RGsB computer video, component video, S-video or composite video input, and are individually configurable.

• Input 7 — Input 7 (on the front panel) includes a VGA-type 15-pin HD connector for RGB computer video input, a 4-pin mini DIN connector for

S-video input, and one RCA connector for composite video input. Input 7 can be configured for one of these video formats, or it can be set to automatically detect the active input.

This input is buffered and can drive a signal approximately 50 feet (15 meters) using Extron cable.

Switcher slaving — Input 1 can be used to connect and control a slaved switcher, expanding the capacity of the System 7SC to a maximum of 16 inputs.

Buffered video outputs — Five rear-panel BNC connectors and one VGA-type

15-pin HD port provide connections for RGB output. Both outputs (the BNCs and the 15-pin HD port) are active at all times.

Seven balanced or unbalanced stereo audio inputs — The front panel mini stereo jack or RCA connectors (for unbalanced input only), and six rear panel captive screw connectors accept audio inputs. Each input’s gain and attenuation levels can be individually set.

Two balanced or unbalanced stereo audio outputs — One fixed line level output

(for a recording device) and one variable line level output (for use with an amplifier or mixer) are provided on 3.5 mm, 5-pole captive screw terminals.

The variable line level output can be controlled via the front panel, the IR 701, optional control pads, or an RS-232 system.

Audio breakaway — Audio and video can be switched separately via RS-232.

Four ways to control the switcher — The switcher’s front panel, a computer or other RS-232 control device, an IR 701 remote control, or a remote keypad can all be used to control the switcher.

RS-232 configuration — The System 7SC can be configured by using the Extron control software for Windows, or by using a third party control system.

Room controls — Two relays are provided for controlling lights, window coverings, a display screen or another item in the room. The Room control buttons can be set to also send an IR or RS-232 command.

Projector control — The System 7SC can control the projector’s display power, video mute and mode functions.

Projector control command learning — The switcher can “learn” new projector control commands by storing IR signals it receives through the front panel, via files downloaded from Extron’s command library, or from commands entered via the Windows-based control program. Learned commands can be associated with any of the front panel input selection or control buttons, and they are output through the IR Emitter/IR Broadcaster or the projector control RS-232 port.

Inactivity projector shutdown timer — Using the included control/configuration software, the switcher can be set to monitor the time elapsed since the last input selection (or other function) and to send a command to turn the projector off after a set period of inactivity.

1-4 System 7SC • Introduction

Triple-Action Switching ™ — With this method, a blank screen is displayed while the System 7SC switches between inputs.

Built-in video scaler — This feature scales all composite, S-video and component video signals up to computer-video rates for output on RGB display devices.

Accu-RATE Frame Lock ™ — The patented Extron Accu-RATE Frame Lock ™ eliminates artifacts from scaled motion video by eliminating frame rate conversion. It locks the output frame rate to the input frame rate of the active input. The result is a switching system that eliminates image tears and other artifacts from motion video.

Dynamic Motion Interpolation (DMI ™ ) — This video processing technique is an advanced motion prediction and compensation method that treats motion content and still content with different algorithms to yield high fidelity images.

3:2 pulldown detection for NTSC and 2:2 film detection for PAL video sources —

These advanced film mode processing features help maximize image detail and sharpness for video sources that originated from film. When film is converted to NTSC video, the film frame rate has to be matched to the video frame rate in a process called 3:2 pulldown. Jaggies and other image artifacts can result if conventional deinterlacing techniques are used on film-source video. The System 7SC’s advanced film mode processing recognizes signals that originated from film. The System 7SC then applies video processing algorithms that optimize the conversion of video that was made with the 3:2 pulldown process. This results in richly detailed images with sharply defined lines. A similar process is used for PAL film-source video.

Versatile mounting options — The System 7SC can be rack mounted, or it can be placed on a table or other furniture. Rubber feet and rack mounting hardware are included.

Options and accessories

The System 7SC’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.

SCP control pads — Up to sixteen (16) Extron SCP/AAP A, SCP 200, and/or

SCP 250 control pads can be connected via a rear panel port. Each SCP replicates some or all of the System 7SC’s front panel controls.

IR Broadcaster — The Extron IR Broadcaster (part #60-272-02) has a greater range than the IR Emitter and transmits signals over a wide area.

Power, video, and audio conections

With the exception of input 7 on the front panel, all input and output connectors are on the rear panel.

Front panel inputs

Input 7 on the front panel accepts video and one audio input. Only one video format and one audio port will be active at a time on the front panel.

The active input type (RGB, S-video, or composite video) can be selected via the

LCD menu (see chapter three, “Operation and Configuration”, for details), or, in autoselect mode, the System 7 automatically detects the active video signal and selects that video signal format. If all formats are active, the default will be RGB computer video input. An LED near each video connector indicates which input type is active.

Each port provides up to 12 VDC for powering the SCP control pads or other devices. However, the total load for both ports combined must not exceed

1 ampere.

The load (such as an SCP control pad or interface) should not be placed further than a maximum of 300 feet (91.4 meters) from the System 7SC switcher.

Contact closure — Connect an optional contact closure control device here.

Select an input channel by making contact closure between an input’s pin

(pins 1 through 7 correspond to inputs 1 through 7) and a ground pin (pins 8,

9, and 10). Continuous connections made by contact closure override all other means of selection: continuous contact closure takes precedence over front panel and RS-232 selection.

Pins 4 and 8 (Tx2 and Rx2) are used to communicate with a slaved switcher (if one is connected). A slave adapter cable (Extron part #26-386-01) is required for slaving. For details, see “Connecting and Slaving A Switcher” in this chapter, and also see “Switcher Setup/Configuration” in chapter three.

Connecting and Slaving a Switcher

One switcher can be connected (slaved) to the System 7SC to allow for a greater number of inputs. The System 7SC serves as the master switcher, communicating with and providing video output to the projector/display. The switcher (“slave”) that is connected to the System 7 provides up to ten (10) additional input connections. See the illustration on the next page for a list of Extron switchers that can be used as slaves.

A System 7SC cannot be used as a slaved switcher.

The RS-232 and video cable connections must be made between the slaved switcher and the System 7 before the System 7 can be configured (via front panel or RS-232) for slaving.

Do not attach any communications or control devices to the slaved switcher except a contact closure remote control, if one is needed.

To connect a slave switcher to the System 7SC, do the following:

1.

Connect the slave switcher’s video and audio outputs to input 1 of the

System 7SC. See “Rear panel inputs”, page 2-5, in this manual, and refer to the slave switcher’s user’s manual for details on cabling.

Each input can be configured in the System 7 for a different signal type (RGB, component video, S-video, composite video), as long as the slaved switcher can handle those signals. As for the System 7SC’s direct inputs, IR and RS-232 commands can also be associated with the slaved inputs.

Once the slaved switcher is connected and configured, its inputs will be the

System 7’s first inputs (input 1 through input 2, 4, 6, 8, or 10). Input 2 of the

System 7 becomes the next input (input 2, 5, 7, 9, or 11).

For example, if a six-input switcher is slaved to the System 7, the slaved switcher’s six inputs are inputs numbers 1, 2, 3, 4, 5, and 6. The inputs labeled as 2 through 6 on the System 7’s rear panel and 7 on the front panel become inputs 7 through 12, as shown in the illustration on the next page.

Labeling Buttons on the System 7SC and SCPs

You may wish to customize the labeling of the System 7SC’s front panel buttons or to make labels for any SCP 200 or SCP 250 control pads that are part of the installation. Premade templates and blank templates for the SCP faceplates’ label windows are printed in the SCP/AAP A, SCP 200, SCP 250 User’s Manual. However, you can easily create, customize, and print labels for the switcher’s buttons or the

SCPs’ button label windows by using the Button-Label Generator software.

2-14 System 7SC • Installation

Button-Label Generator software

The Extron Button-Label Generator program (Buttons.exe) is included with the

System 7SC, and it can also be downloaded from the Extron Web site

(http://www.extron.com). This program is used to create and print labels that can be inserted into the illuminated pushbuttons or placed in slots above/below buttons on the SCPs and on various Extron switchers.

Installing the software

This program is installed at the same time the System 7SC control program is installed. No additional steps are required. See page 4-11 of this manual for installation instructions.

Using the software

1.

To run the Button-Label Generator program, double-click on the Button-Label

Generator icon (shown at left) in the Extron Electronics group or folder, and click OK when prompted.

2.

Under System selection, choose the item that corresponds to the device for which you want to make labels: System 7SC, SCP 200, or SCP 250. The button label editing area changes to reflect the number and arrangement of buttons on the device.

3.

Using normal Windows controls, you can create and print labels that can be cut out and placed in the label windows on the front panel of the switcher.

For information about using the program, you can access a help file by clicking on the Help menu on the main screen and choosing Show Help.

You can also see an example of a completed Extron’s Button-Label Generator window by clicking on the Help menu on the main screen, choosing Show Help, and clicking on the Load Demo button.

When the System 7 powers up, all of the front panel LEDs light while the control buttons and then the input selection buttons light briefly in sequence, then the LEDs turn off.

Each of the front panel buttons can have an RS-232 command and/or an

IR command associated with it. If the button is set up via the Windows-based control program, pressing an input selection button could select that input and have the System 7 send an RS-232 command and/or an IR command.

Control features

Display buttons: Display Power, Display Mute, Mode — Each of these three buttons can be configured/programmed to perform or send either an infrared (IR) command or an RS-232 command. Display Power and Display

Mute each have two memory blocks that can store 256 bytes of information apiece.

The settings of the display buttons 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. When a display button is pressed or activated by RS-232, one of the following messages is displayed on the LCD screen:

Display Power button

To send a power-on command, press and hold the Display Power button for two seconds. At the end of two seconds, the button will flash twice, then glow steadily while the display device is on.

If AC power is removed from the switcher while Display Power is on, the switcher will send an RS-232 power-off command to the display device before shutting down. The System 7 cannot send a power-off command via IR after power has been disconnected.

To turn the display device off, again press and hold the Display Power button for two seconds. The System 7 will send the power-off command, and the Display Power button will flash twice, then turn off

(go dark). Many projectors require a power-off delay. The System 7 has a brief power-off delay, during which the power-off command is resent to the display device.

To shut down the projector if the switcher hasn’t been used for a set amount of time, a built-in inactivity shutdown timer can be set by using the included control software. If the inactivity timer is enabled, the switcher monitors the time elapsed since the last input selection (or other function) and sends a display power off command (or that command and any other commands associated with the Display Power button) after a set period of inactivity. That period can be selected in fifteen-minute increments to be as long as 480 minutes (8 hours). See chapter four, “Serial Communication”, for details. To turn the projector on again after it has shut down, you must press the Display Power button, click the Display Power button within the control software, or send the switcher the 1P SIS command via RS-232.

The Display Power button can also have the functions of one of the

Room buttons assigned to it. The associated room function (relay activation + associated commands) can be executed immediately after the Display Power IR and/or RS-232 commands are sent. The Room button will light when the room function is executed.

Display Mute button

Once it has been programmed for use with the projector, press and release this button to send a mute on/off command to the display device.

The button will not flash before sending the command.

Display Mute is only active when Display Power is on.

Mode button

Press this button to execute any IR or RS-232 command that has been programmed into its memory. For example, it can be used to switch the mode of the projector between computer video (RGB), S-video, and composite video, replicating the 1-button (step) mode function provided on some projectors’ remote controls.

Each of the Display buttons can be set up to send an IR signal immediately after sending an RS-232 signal once the button is pressed.

Room buttons — Room 1 and Room 2 control the rear panel Relay ports, which control “room” functions–items such as room lighting, window coverings, and display screens–via momentary or latching contact. These contacts may be used to control any equipment as long as the contact specifications of a total of 24 volts at 1 ampere are not exceeded. The Room buttons light while the room functions are active (on). Each Room button can also be set to send an IR or RS-232 command when the button is pressed. If the Display Power button has a Room function assigned to it, the Room button will light when Display Power has been pressed, and the room function will be executed.

See page 2-9 for information on the Relay ports, and see chapter 4, “Serial

Communication”, and refer to the Windows-based System 7SC Help program for details on changing settings.

Volume control knob — Turn this knob to adjust the audio volume (gain) for the Variable (preamp) audio output. There is no physical limit to this knob’s rotation. During volume adjustment the LCD screen displays a bar graph

(shown below), which also indicates when the knob has reached its functional minimum or maximum limit. The minimum setting produces 100% signal attenuation.

Min Volume Max Min Volume Max Min Volume Max

In normal mode (not setup mode) the volume control does not affect the Fixed audio output, only the Variable audio output. See pages 2-6 and 2-7 for details on the two audio outputs.

Adjustment features

The settings of each type of adjustment (image, centering, zoom, and volume adjustments) are stored in separate memories for each input.

Executive mode locks all front panel functions except input selection and control commands (display and room functions) and disables setup menu options. The System 7SC’s front panel and the IR 701 are both affected by executive mode; adjustment features will not be accessible from the front panel and the IR 701 when executive mode is active. However, all functions and adjustments can still be made through RS-232 control. For details on RS-232 control, see chapter four.

Input selection buttons — These buttons correspond to the seven inputs.

When you select an input, the corresponding button lights and remains lit until another input is selected or power is removed. The factory default (and reset default) is for input one to be active. However, the last input selected before power down will be active when the switcher is powered up.

All inputs accept RGB computer video, S-video, or composite video. Inputs one through six also accept component video (YUV). When an input button is pressed, the LCD displays the input number and video format, as shown below.

If the audio is “broken away” from (switched independently of) the video, the input selection button corresponding to the selected audio input flashes, and the input button corresponding to the video input lights steadily. Audio breakaway can be set up only via RS-232 control. Audio-only and video-only modes are available via RS-232 , but if both audio and video are set to input 0, no audio or video will be output, and none of the input selection buttons will light.

Each of the input selection buttons can also be configured to perform either an IR command, an RS-232 command, or both, just like the Display buttons.

Each input button has a memory block of 256 bytes available for storing a command. For details, see the section on projector control in this chapter.

System 7SC receives an RS-232 confirmation signal from the projector.

If the Rx LED blinks instead of the Tx LED during command transmission, there is an internal error. Call the Extron S3 Sales and Technical Support

Hotline.

Configuration must be done using the front panel controls or RS-232 control.

Configuration cannot be done from the IR 701.

Learn — This contains the IR learning device. The System 7SC can “learn” commands in order to control the projector. IR learning is only necessary if there is no IR driver file available for that projector or if the driver is not complete. The IR learning procedure is discussed in

“Menus, Configuration, and Adjustments” in this chapter.

System 7SC • Operation and Configuration 3-5

Operation and Configuration, cont’d

IR and RS-232 Projector Control

The System 7SC switcher can control a projector or other display device by using IR control signals or RS-232 control (one-way or two-way control). The switcher must be configured for projector control in one of the following ways before it will send commands to the projector:

• An IR or an RS-232 driver file can be downloaded from a disk or the Extron Web site into the switcher.

• RS-232 command strings can be entered directly from a host computer using the supplied Windows-based control software.

• IR commands can be entered directly from an IR remote control into the System 7 through IR learning.

Projector control memory

There are two sets of memory for projector control commands:

Memory page 1: IR learning memory — This stores any IR commands that have been “learned” by the switcher. The System 7SC can “learn” projector control commands from a projector’s IR remote control. The IR learning procedure is discussed in “Menus, Configuration, and Adjustments” in this chapter.

Memory page 0: download/user-defined memory — This stores all downloaded

IR and RS-232 projector driver files, and also any user-defined RS-232 command strings.

RS-232 signals are sent to the projector via hardwired connection

Each time a new projector driver is downloaded into the System 7’s download/ user-defined memory, all previously downloaded drivers (IR or RS-232) and userdefined RS-232 commands will be replaced (overwritten or deleted) by the new driver. Similarly, entering user-defined RS-232 projector commands will also cause all previously downloaded drivers and user-defined commands to be replaced.

Entering or editing an RS-232 command will change the “owner” status. See chapter four, “Serial Communication” for details.

Learned IR commands will not be affected when a new driver or command string is downloaded. Because learned IR commands are stored in a different memory location, learned IR commands can be executed at the same time as RS-232 commands.

Example

A projector can be hardwired to the System 7’s 10-pole projector control port for

RS-232 communication, and an IR Emitter or IR Broadcaster can be connected to the

5-pole IR Comm port. If the System 7 “learns” IR commands for a plasma display, and an RS-232 projector driver is also downloaded to the switcher, the System 7 can control both display devices simultaneously. If an Extron IR projector driver is then downloaded to the System 7, the RS-232 commands are replaced by the new driver,

3-6 System 7SC • Operation and Configuration

and both the learned and downloaded IR commands will be sent out the IR Comm port to the IR Emitter or IR Broadcaster.

Optimizing the System

For optimal performance, follow the steps in this section in order when setting up the System 7SC and its input and output devices.

Setting up a DVD source

To get the best results when using a DVD as a video source, Extron recommends that the DVD player itself be setup to output an aspect ratio of 16:9 and not 4:3.

Because all DVDs are mastered as 16:9, having them set up for anything else will cause the player to internally scale and compress the signal. This scaling/ compression by the DVD player will defeat the advantage of having 3-2 pulldown detection in the System 7SC.

To change the output aspect ratio of most DVD players,

1.

Enter the DVD player’s Setup or Action menu while the disc is stopped.

2.

Select a 16:9 aspect ratio.

Setting up the System 7SC

Detailed information on each configuration step can be found in the “Menus,

RGB Delay (Triple-Action Switching

)

With Triple-Action Switching, the System 7 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. Triple-Action Switching is also known as video mute switching.

Use the Adjust knob to select the blanking period (RGB delay time) from 0 seconds

(default) to 5 seconds in half-second steps.

Scaler Blue Out

To aid in setup of the scaler’s color and tint, Scaler Adjust Blue Only can be set to

“Yes” so that only sync and blue video signals will be passed to the display. Use the

Adjust knob to select this option, which can be used for scaled video output only.

The System 7SC with a slaved switcher

After the slave switcher has been connected to the System 7 and both switchers are powered on, select the input quantity (10, 8, 6, or 4 inputs) that corresponds to the attached slave switcher from the Add Slave submenu of the Switcher Setup/

Configuration menu.

Autoselect #7 (front panel input automatic signal type selection)

The front panel input (input 7) accepts video and one audio input. Only one video format and one audio port will be active at a time on the front panel.

The active input type (RGB, S-video, or composite video) can be specified via the

LCD menu, or, in autoselect mode, the System 7SC automatically detects the active video signal and selects that signal type whenever input 7 is active/selected. The lowest voltage level that can be detected by the switcher is 2.0 Vp-p.

System 7SC • Operation and Configuration 3-11

Operation and Configuration, cont’d

An LED near each video connector indicates which input type is active. Select

“Yes” from the Autoselect #7 submenu to activate autoselection.

If the autoselect feature is on, the last input (input 7 if no slave is attached) is selected, and video signals are present at all ports for that input, computer video (RGB) will be selected as the default source.

Inputs are autoselected as follows:

• RGB input (highest priority),

• S-video input,

• composite video input (lowest priority).

The LCD will display Autoselect #7 if the System 7 is not set up for a slaved switcher. If a switcher is slaved to the System 7, the LCD will display

Autoselect #10, Autoselect #12, Autoselect #14, or Autoselect #16, depending on the size of the slaved switcher.

Audio Level

From this submenu audio levels can be adjusted per input from -15 dB to +9 dB in

0.5 dB increments. This allows the signal to be boosted or trimmed to a consistent output level so that there is no noticeable difference in level when switching between inputs. This adjustment applies to both the Fixed and the Variable audio output.

The Volume adjustment, which affects the Variable audio output only, is applied to all inputs equally, and it is an attenuation applied in addition to the per-input audio level adjustments made using this submenu.

Blank Input (blanking adjustment)

To remove noise or extraneous material such as closed captioning by removing scan lines at either the top or bottom of the screen, adjust the top blanking or bottom blanking. Rotate the vertical shift knob to set the number of lines removed from top of the picture. Rotate the horizontal shift knob to set the number of lines removed from the bottom.

Image Size

To proportionately resize the displayed picture without altering the aspect ratio, rotate either the vertical ( ) or the horizontal ( ) shift knob while in the Image Size submenu. Whichever knob is used, the effect is the same: proportional picture sizing.

During Image Size adjustment, if a horizontal or a vertical size limit is reached, the sizing stops, and the aspect ratio remains unchanged. The LCD screen displays Min or Max.

Size Input

To resize a picture, enter the Size submenu, then rotate the vertical( ) shift knob to make the picture taller or shorter, or rotate the horizontal ( ) shift knob to make the picture wider or narrower. The amount of adjustment available depends on the selected output rate.

If a sizing limit has been reached, the LCD screen will display Min or Max.

System 7SC • Operation and Configuration 3-13

IR Learning Configuration

Via an RS-232 connection, infrared commands can be downloaded into the switcher as driver files from Extron’s Web site. The System 7SC can also “learn” IR commands directly from a display’s remote control. IR learning is convenient for installing new or updated commands into the System 7SC while in the field.

IR commands can be associated with any front panel control (Display Power,

Display Mute, Mode, Room 1, Room 2) or input selection button. Pressing one of those buttons will only cause an IR command to be executed if a command has been programmed into the System 7SC and associated with that button.

The Display Power and Display Mute buttons each have two memory blocks for IR or RS-232 information in order to meet the needs of many displays that require separate commands for power on/power off and mute on/mute off.

The IR Learning Configuration menu provides a way to initiate IR Learning and to designate which front panel button will have which command associated with it.

The flowchart below shows how to move through the IR Learning Configuration submenu.

Serial Communication

The System 7SC 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 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 7SC 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 7SC 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 2001, Extron Electronics, System 7SC, Vx.xx

The System 7SC sends the copyright message when it first powers on. Vx.xx is the firmware version number.

C hn

X1

(where

X1

is the input number)

The System 7SC 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 7SC is unable to execute the command because the command is invalid or it contains invalid parameters, it returns an error response to the host.

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. Except when setting audio gain/attenuation, upper and lower case characters may be used interchangeably in the command field.

Control Software for Windows

®

The included Extron SYSTEM 7SC Control Program for Windows offers another way to control the System 7 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 Windows-based software.

The control software must be used in order to download projector driver files into the System 7.

The control software is compatible with Windows 95/98, Windows NT, Windows

2000, and up. Extron’s System 7SC Control Program is included with the System 7, and updates can be downloaded from the Extron Web site

(http://www.extron.com).

Installing the software

The control program is contained on a set of 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:\System7 directory, and it places two icons

(SYSTEM 7SC Control Pgm and SYSTEM 7SC Help) into a group or folder named

“Extron Electronics”.

Using the control program

Many items found in the System 7SC Control Program are also accessible via front panel controls and the LCD menus described in chapters two and three. Refer to those chapters for details on features and settings. The SYSTEM 7SC Help Program provides information on settings and on how to use the control program itself.

Some features, including the miscellaneous options, are only available via this control program. These features are described in the sections of this chapter that correspond to the parts of the control program where the features are found.

1.

To run the control program, double-click on the SYSTEM 7SC 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 7SC’s RS-232 port.

The Extron SYSTEM 7SC Control Program windows appear. The projector driver, port, and firmware information are displayed at the bottom of the screen. There are several views available: the Mini Mode screen, the User Mode screen, the I/O Configuration screen, the Real Time Adjustments screen, the

Projector Driver screen, and the Room & Misc. Options screen.

Mini Mode

The Mini Mode screen, shown below, allows input selection only.

System 7SC • Serial Communication 4-11

Serial Communication, cont’d

User Mode

The User Mode screen, shown here, includes the most frequently used controls: input selection, projector and room controls, variable output volume control, audio/video breakaway, freeze, and executive mode toggling.

Special features

Freeze — Activating Freeze causes the output image to be still (frozen). This applies only to scaled outputs (non-RGB inputs).

Disable Front Panel — Enabling this feature locks the switcher’s entire front panel so no changes can be made at the switcher. It does not affect the SCP control pads. Input selection and display/projector control can be performed from the IR 701 or via RS-232; adjustments can be done only through RS-232 control when Disable Front Panel is on.

Disable Image Controls — This is feature is identical to Executive Mode, which is enabled by pressing the Color and Detail buttons at the same time. Disable

Image Controls locks the picture adjustment and centering controls, but not the volume, input selection, and display controls.

I/O Configuration

The I/O Configuration screen, shown at left, allows you to select video input formats, scaler and sync output options, and RGB delay (Triple-Action switching delay time) settings. These settings are described in “Menus,

Configuration, and

Adjustments” in chapter three.

4-12 System 7SC • Serial Communication

Real Time Adjustments

The Real Time

Adjustments screen lets you adjust the picture settings and audio gain/attenuation for each input. From this menu you can also reset some or all of the settings to the original factory-installed settings.

Special features

Reset to Factory Defaults — The reset features in the control program let you reset specific groups of functions.

Reset Audio Input Levels sets all inputs’ audio levels to 0.0 dB.

Reset all picture Image, Position, and Size controls sets all inputs’ video adjustments (color, tint, contrast, brightness, detail, centering, sizing) to their factory default values.

• The Reset to Default feature available through the front panel LCD menus

(see page 3-17) combines Reset Audio Input Levels and Reset all picture

Image, Position, and Size controls. It resets all of the per-input adjustments for audio level, picture adjustments, and centering.

None of the above reset options will reset the input formats, room relays, or

IR/RS-232 drivers.

Total Factory Reset! is a global system reset that clears all settings including audio and video adjustments and IR and RS-232 commands and drivers.

This is the same as the manual global reset. To reset the switcher manually press and hold the Menu and Next keys on the front panel while connecting the System 7 to an AC power source.

Projector Driver

The Projector Driver screen displays the current IR and RS-232 parameters and commands.

Commands and drivers can be loaded, entered (programmed), or edited from this screen. Using this screen, commands can be associated with each input selection, display/projector control, or room button.

Special features

All of the items found in this screen are only available in this part of the control program. There is no other way to perform these functions. After loading a projector driver, but before editing or programming RS-232 commands, click on the button (such as Room 1 or Power Off in the upper part of the Projector Driver screen) that you wish to edit or program. The System 7SC Help program provides step-by-step directions for programming buttons.

Load New Driver — Select this button to load a new, Extron-created projector driver file into the System 7SC and into the control program. Alternatively, you can select the Load New Driver From... option in the File menu.

Remove IR/232 — Clicking on this option will erase the IR and RS-232 commands that are stored in the memory for the selected button.

Page 0 sends — This feature shows what type of commands (IR, RS-232, or none) the button is programmed to send. Choose RS-232 if you wish to program unidirectional RS-232 commands for the selected button.

RS-232 Uni-directional Commands — The location and hexadecimal and ASCII forms of any unidirectional RS-232 commands that have been programmed into the selected key will be displayed in this area. Commands and command length can also be entered or edited in this area. Refer to the

System 7SC Help program for complete step-by-step programming directions.

IR/RS-232 params — This section shows parameter information about the command stored in memory for the selected button.

4-14 System 7SC • Serial Communication

Room & Misc. Options

Use the Room & Misc.

Options screen to set room relay modes and delay periods, power up/down delay periods, change projector communications settings, and perform other functions.

Special features

Tie (room relay) to Power — Enabling this feature for room relay 1 or room relay 2 will cause that relay to turn on/off when the Display Power is turned on or off.

Projector Comm — Set communications protocol (RS-232 vs. RS-422, baud rate, parity, data bits) in this section.

Misc. Options — This section provides a way to send (or not send) various commands, to mute audio, and to lock input selection when the Display

Power is turned on or off. Descriptions of each item are available in the

System 7SC Help file.

Limit initial power-up volume — Here you can specify an attenuation level for the initial volume of the audio output. If the Limit initial power-up volume box is not checked (enabled) or if the limit is set to 100%, the volume will not be limited (attenuated).

Auto shutoff — If Auto shutoff is enabled, the switcher monitors the time elapsed since the last input selection (or other function) and sends a display power off command (or that command and any other commands associated with the

Display Power button) after a set period of inactivity. That period can be selected in fifteen-minute increments to be as long as 480 minutes (8 hours).

Saving and restoring configurations

The System 7SC 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 7SC Control Program, select File, then select Save Configuration as... .

2.

Firmware Upgrade Installation

In some cases the System 7SC’s firmware may require replacement with an updated version. The user-replaceable firmware chip is U70, the main microcontroller. We recommend that you send the unit in to Extron for service and updates.

Changes to firmware must be performed by authorized service personnel only. Some System 7SC firmware updates must be performed at the

Extron factory.

Follow these steps to replace firmware in the System 7SC.

1.

Disconnect the AC power cord from the System 7SC to remove power from the unit.

To prevent electric shock, always unplug the System 7SC 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. The fan is connected to the side of the cover. Do not disconnect the fan; set the cover down on the side that has the attached fan.

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 chip U70 on the circuit board, as shown in the following illustration.

Align Notches

5.

After you are electrically grounded, align the hooks of a PLCC IC puller tool with the slots located in opposite ends of the firmware chip.

6.

Insert the hooks into the slots, and squeeze the tool gently to grasp the chip.

7.

Pull the chip straight out of the socket, and set it aside.

8.

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.

Replace the top cover on the System 7SC switcher, and fasten it with the screws that were removed in step 3.

11.

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 -3 dB. 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.

IR learning — The ability of a device 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 (www.extron.com).

Latching — The System 7SC 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 7SC 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.

3:2 pulldown — The process of matching the frame rate of film (24 frames per second) to the frame rate of video (30 frames per second for NTSC video). In

3:2 pulldown, one frame of film is converted to three fields (1½ frames) of video, and the next frame of film is converted to two fields (1 frame) of video.

This process is repeated (yielding 3 fields of video, 2 fields, 3 fields, 2 fields,...) until the film is fully converted to a video of approximately the same length (duration). Most scan doublers, quadruplers, and scalers use the premise that two fields of video equal one frame, but video created via 3:2 pulldown does not follow that pattern.
