System 4xi Features

Chapter 1 • Introduction and Features

Universal Video Inputs

The System 4xi has four universal inputs, each capable of accepting all computer RGB signals from 15 kHz to 150 kHz, any composite video standard signals (NTSC or PAL) and S-video (S-VHS) signals. There are no optional modules to purchase for each input signal type.

Quad-standard Decoder

The System 4xi is compatible with all standard video formats including NTSC

3.58, NTSC 4.43, PAL and SECAM.

Balanced/Unbalanced Audio Inputs

Every System 4xi is capable of switching up to four balanced or unbalanced, left and right stereo audio signals. Audio, input through professional-style captive screw connectors, can be switched to follow any video or RGB input signal, or it may be switched separately for added flexibility (see “Breakaway” below).

Audio Follow/Breakaway

When switching inputs, the System 4xi can either select audio and video from the same source (Audio Follow) or select audio from one source and video from another (Breakaway).

Three-line Adaptive Comb Filter

A built-in, three-line adaptive comb filter helps to provide a crisp, stable output from the System 4LDxi and 4LQxi.

Built-In Line Doubler/Quadrupler (scan doubler/quadrupler)

The System 4LDxi and 4LQxi include a built-in NTSC or PAL compatible line doubler or line quadrupler (4LQxi only) that is capable of line-doubling/ quadrupling composite video, S-video or RGB video (Targa or document camera) signals. The signal also passes through a digital noise filter to improve the picture. The line-doubled/quadrupled output results in a sharper image with less noticeable scan lines and “video noise.”

300 MHz RGB Video Bandwidth

The 300 MHz RGB video bandwidth of the System 4xi makes it two to three times the performance of any other presentation switcher.

LCD Menu-Driven Picture and Programming Controls

The System 4LDxi ’s LCD menu makes setup and programming of its features and functions easy and flawless. An alphanumeric display allows for any of the line-doubler/quadrupler controls such as color, hue and contrast to be adjusted to exact specifications for each input.

RGB Output

The System 4xi video output will be RGBS or RGBHV if the selected input is configured to be line-doubled or line-quadrupled. If the selected input is not configured to be line-doubled/quadrupled, the output video format will be the same as the input.

RS-232 Control

The System 4xi has built-in RS-232 control for external/third party control of any of its features or functions.

Triple-Action Switching™ RGB Delay Switching

Triple-Action Switching makes it possible to have “seamless” picture switching. The System 4xi may be programmed to switch the RGB signals to the projector at a specified time after the sync is switched (0 to 5 seconds, in 1/2 second increments). The audience will briefly see a blank screen while the projector “locks on” to the input signal.

Extron • System 4xi Switcher Series • User’s Manual

1-2

Chapter 1 • Introduction and Features

Multiple Switcher Applications

The features of the System 4xi can be further expanded by connecting the output from another switcher to Input #4. The System 4xi then functions as the “master”, communicating with the projector and providing it with a signal improved by any of the features described in this section and, if required, can even control the connected projector using their IR (Infra-Red) remote control, RS-232 control, or the built-in LCD menu-driven System 4xi front panel control.

Picture Control Memory

All inputs, including those in multiple switcher applications, have a separate memory block for all picture controls of video or RGB and audio signals. When a different video input is selected, the picture controls are updated automatically from the information stored in the Picture Control Memory. RGB inputs in passthrough mode have no stored picture control information.

Internal Power Supply with Automatic Switching

The System 4xi is equipped with an internal auto-switching power supply that operates from any input voltage in the 100-240 VAC range, at 50/60Hz.

Universal Projector Control

The E

XTRON System 4xi and the projector operate as a system that can be

controlled several ways:

•

through existing projector controls

•

through the System 4xi panel

•

through a host system using the RS-232 port

•

using Extron’s Windows® Control software

Using the projector-brand remote control, the System 4xi can be made to control the following operations:

•

switch inputs

•

control projector power

•

mute the audio or video signals

•

switch input memory blocks (in projector) for convergence

• setup saved configurations within the connected projector by input selection

•

monitor the projector for update changes, feature changes, or input selection

changes by the user

The above operations can also be accomplished by using the System 4xi front panel controls or through a PC or other control system. The System 4xi switcher will communicate with the projector and pass it the desired command.

When a projector manufacturer introduces a new model, the System 4xi can be upgraded to accommodate it by a simple EPROM change (free during the warranty period of two years). When a totally new projector brand and model is introduced, Extron will either add it to the compatibility list for EPROM upgrades, or make it an available “standard” with all future System 4xi switchers. Call Extron with details of your requirements.

The unique control features of the System 4xi make using its switcher functions exactly the same as using the projector-brand switcher, but with a 300 MHz bandwidth performance — nearly three times that of most projector- brand switchers.

1-3

_______ Some projector IR remotes do not communicate with the System 4xi. Also, all

projectors have different methods for source and memory recall of source inputs. Please refer to your specific installation instructions for further details.

3. Set the switches as indicated by the label or the instructions included with the projector communications kit and verify that the Projector cable is on the correct connector (J9/J15).

_______ Extron continues to support new projectors. If you have questions about using

the System 4xi with a device for which you cannot find configuration settings, please consult with your Extron representative.

4. Refer to the appropriate cabling procedure included with the projector communications kit to continue the installation.

Cabling a System 4xi in a Rack

When routing cables from one unit to another in a rack, do NOT allow the cables to be supported by the System 4xi (see Figure 2-7). Use “Tie Wraps”, “Rip-Ties” or other devices, to secure the cables at some point in the rack that is above the rear panel connectors. Loosely hanging cables may be stepped upon, resulting in damage to cables and equipment, as well as injury to personnel.

The example shown in Figure 2-6 has the cables tied to the rack above the connections to the equipment. This allows an unobstructed view of the rear panel connectors, and prevents the cable weight from pulling down on the equipment.

_________ Be sure that no weight is added to the System 4xi in excess of 10 lbs (3.73 kg). _________ The holes in the top and bottom of the System 4xi enclosure are for cooling.

Do NOT cover these holes. This could cause overheating of vital components.

_________ Maximum ambient operating temperature must not exceed 104° F (40° C). _________ The mounting rack, and all equipment mounted in it, must be grounded

according to national and local electrical codes.

_______ Keep power and signal cables separate (power cables on the right and signal

cables on the left.)

Audio Terminal Connections

The rear of the System 4xi has five audio connectors (four input and one output). Each connector has six pins for a left and a right audio channel. One example is shown here in Figure 2-8.

The 6-terminal, captive screw connectors are supplied with the switcher for wiring the audio cables. The connectors are then plugged into the appropriate position in the audio terminal strip on the rear panel. The audio area of the back panel is labeled “R” (right) and “L” (left) for each channel.

When wiring the connectors and plugging them into the System 4xi switcher, the screw heads (see figure right) must face down.

When the System 4xi is powered up, a Title screen appears briefly, followed by the Default display. Examples are shown to the left. This manual covers different System 4xi models; an appropriate screen will appear displaying your model and software version.

The Default screen (shown to the right) will continue to display whenever the panel is not being used. It displays the current status of the input(s), with the following information:

Video Configuration

The top line displays which video input channel is selected and its Video Mode. The example shows that Video input #1 is selected, with RGB and Sync. Other modes are explained later. The Arrow to the left (® VID) indicates that video is being switched (not Breakaway).

Audio Configuration

The second line provides the current audio configuration. The example shows that Audio input #1 is selected and the arrow (® AUD) indicates that audio is being switched (Audio Follow). The gain/attenuation is set at 0 dB for that input.

Breakaway

As mentioned earlier, the Breakaway button allows Audio and Video to be separated. The three breakaway steps are: Video and Audio (both), Video only, and Audio only. The Default Display indicates this condition by turning off the arrow for the signal that is not being sent to the output.

Audio Mute

As stated on the previous page, the Audio Mute button temporarily turns the audio Off. The Default Display indicates this condition by alternately displaying the word "Muting" and the dB level.

When the default menu is being displayed, pressing a Front Panel button will then change the screen to display appropriate information. These LCD screens, or menus, are explained later.

System 4xi Model Differences

This chapter covers all both System 4xi models. Each model has different features, and a different Front Panel. Because the System 4LDxi and 4LQxi have the most features, page 3-1 shows a 4LDxi front panel; all System 4xi panels are shown below. The most obvious differences are in the number of Picture Control buttons. Other differences will appear when using the LCD menus.

Chapter 4 • Connecting Multiple Switchers

Looping the System 4xi with Other Switchers

The System 4xi can be interconnected, or “looped” with other switchers to allow for a greater number of inputs to be switched to the projector. With each of these configurations, the System 4xi acts as the “Master”, to communicate with the projector and supply the video signal. The switcher that provides input to the System 4xi is the “Slave”. If two switchers are looped with the System 4xi, the second switcher is a “Slave” to the first, and the first is a “Slave” to the System 4xi.

• The slave switcher is always connected to the highest master input (input #4

on a System 4xi, input #10 on a System 10 and input #8 on a System 8, etc.).

• Input numbering always starts at input #1 of the System 4xi and input #4 will

become the first input from the “slave” switcher.

• The System 4xi cannot be used as a slave switcher.

• The only switchers that can be looped with the System 4xi are:

Extron’s SW4 ARMX, SW6 ARMX, System 8 P

• In any master/slave arrangement, the System 4xi acts as if it is one large

switcher. That is, each slave input can be selected and set up from the System 4 type. For example, a System 4LDxi with a System 8 P software as a line-doubling, 11-input switcher.

Input Channel Addressing

The System 4xi must be set up to recognize input that is from another switcher unit. The Front Panel operation in Chapter 3 explains how this is done. In a master/slave configuration, input channel numbers of 4 or higher are translated and sent to the appropriate slave input number. For example, selecting input #9 will select input #4 on the System 4xi, and then tell the slave switcher to select its input #6. See shaded table entry below.

Channel Sys4 SW4 SW6 SW8+ SW10+ Multiple SW8+/SW10+

Ch #1 Ch #1 Ch #2 Ch #2 Ch #3 Ch #3

Ch #4 Ch #4 Ch #1 Ch #1 Ch #1 Ch #1 Ch #1 (1st SW10) Ch #5 Ch #4 Ch #2 Ch #2 Ch #2 Ch #2 Ch #2 Ch #6 Ch #4 Ch #3 Ch #3 Ch #3 Ch #3 Ch #3 Ch #7 Ch #4 Ch #4 Ch #4 Ch #4 Ch #4 Ch #4

* Channel numbers continue if multiple switchers are used as slaves. The highest number of channels is 22, using two System 10 PLUS units as slaves.

The following pages show configurations for looping the System 4xi with other Extron-approved switchers. Looping the System 4xi will not work with all switchers; call Extron Electronics if you have any questions.

Extron • System 4xi Switcher Series • User’s Manual

Controlling Master/Slave Switchers

Slave Switcher

When a host system is controlling a System 4xi with a switcher as a slave, a special 9-pin T-Connector cable, called a “System 4xi Slave Adapter” is necessary. Pictured below, in Figure 4-1, the connector marked “Slave” is a 9pin male connector designed to work with the switchers described in this section.

Communications between the System 4xi (master) and the slave is done through a second port on the same connector. The adapter puts this second set of signals on the “normal” transmit/receive lines (pins 2 and 3) on the slave connector. Because Host devices tend to use pins 4 and 8 for CTS and DTR signaling, those pins must be disabled.

_________ Referred to as Rx2 and Tx2, on pins 4 and 8, these pins* must not be used for

other signals in the Host System. It may be necessary to disconnect pins 4 and 8 at the Host side.

The J1 connector connects to the J2 connector which connects to the J3 connector.

J1 Pins (System 4xi) J2 Pins (Host) J3 Pins (Slave Switcher)

1 - n/c 1 - n/c 1 - n/c 2 - Tx 2 - Rx 2 - Tx2 (slave to host)

3 - Rx 3 - Tx 3 - Rx2 (host to slave) 4 - Tx2 4 - *Tx2 4 - n/c 5 - Gnd 5 - Gnd 5 - Gnd 6 - n/c 6 - n/c 6 - n/c 7 - n/c 7 - n/c 7 - n/c 8 - Rx2 8 - *Rx2 8 - n/c

The picture in Figure 4-2 shows an SW6 ARMX as an example, although it would also apply to an SW4 ARMX. Connect the video output of the ARMX switcher (SW4 or SW6) to the last (4th) input of the System 4xi.

_______ Regardless of how the slave switcher input connectors are marked, they must

Programming the System 4xi Looping Configuration

After making all the connections for a master/ slave system, turn power on for all the units involved and access Menu 5 (Slave Cfg). Use the or to step to the correct configuration, and then press to save the setting to memory.

_______ This procedure may be done before connecting

the slave(s) to the System 4xi, if that is more convenient.

Testing the Master/Slave Communications

Press to go back to the menu selection again. Step to the Switch Slave menu (Menu 9 if System 4LDxi/4LQxi – otherwise Menu 8). This menu will only appear if there is a slave configured.

Press to get the Switch Slave Menu (shown below). The display will show Channel 4 because that is the first slave channel.

Use the and to step to a slave channel and press to select it. Once selected, look at the front panel of the slave unit to see that the correct channel has been selected. Using the table on page 4-1, select channel #6 and channel #3 will light on the slave switcher. Repeat this procedure for each available slave channel. (Only the available channels will show in the LCD display.)

Now test the switcher communications in reverse by pressing a channel switch on the slave and see that its system channel number appears in the LCD display. Again, use the table on page 4-1 as a reference.

Once the master/slave system is checked out, all of the available channels can be accessed and set up from the System 4xi front panel with Menus 1 and 2. The channel numbers will be as listed in the left column of the table on page 4-1.

Extron System Switcher Control Software

This chapter is dedicated to using Extron’s “Windows Control Program for System Switchers via RS-232” software. Extron supplies this software that runs in the Windows® operating system, version 3.1 or later (Windows95® and Windows98®). It works with several Extron system switchers, including the System 4xi series. Communication between the computer software and the switcher is established after connecting the computer to the RS-232 Port on the rear panel of the System 4xi, as follows:

1. Connect the PC’s Comm port to the RS-232 on the back of the System 4xi.

2. Power up the System 4xi and the PC and start Windows.

_______ The floppy disk has

instructions printed on the label. The software can be run from the floppy drive, or loaded onto the PC’s hard drive.

3. Install the software from the

3.5” floppy disk onto the hard disk like any other Windows application. (Run Setup.exe from the floppy disk.)

_______ Although this

software was designed to control any System 4

switcher, its operation will be restricted to the

SYSTEM 4/8/10+

features and configuration of your unit.

4. To run the System Switcher Control program, double-click on the SYSTEM

Figure 5-1. Connect the PC to the System 4xi.

SWITCHER Control Pgm icon in the Extron Electronics group or folder. The

System 4xi Help

Chapter 5 • Using Windows® Control Software

The fastest way to learn what each Windows® function does is through the Help menus. At any time, help is available by double-clicking the Help icon (previous section), pulling down the Help menu or by pressing F1. This will bring up the Help menu (like the example shown below) to allow you to step through the screen examples. Click on the items on each screen to display a description.

_________ As with all Windows® Help menus, clicking on the underlined words will give

more detailed help.

Figure 5-3. Example of the first Help menu, Help Contents

After viewing the Help menus, use the software to setup your System 4xi. Specific examples are given below.

Each function on the front panel of your System 4xi is emulated in the software panel in the window. Also, the software was written to operate with different models of switchers. Therefore, any function that is not available on your model will be inactive in the window. A function is inactive when it appears dull, or gray, and does not respond to the mouse cursor.

Chapter 5 • Using Windows® Control Software

Windows Control Panel Examples:

As mentioned earlier, the window panels have the same functions as the System 4xi front panel. Figure 5-4 shows four input buttons for the System 4xi, while Figure 5-5 shows 11 inputs. This is an example of a System 4xi, with a System 8 Plus switcher as a slave unit. Inputs 1, 2 and 3 may each have a video device connected. However, Inputs 4 through 11 are actually Inputs 1 through 8 of the slave switcher connected to the System 4xi (8 + 3 = 11 inputs).

Although the Help menus have detailed information on the software functions, here are some brief descriptions.

MAIN POWER – in the upper-left corner, is the same as the Power button on the

System 4xi front panel. It turns the switcher off or on.

_________ When this button is in the off position, power is still present inside the System 4

enclosure.

INPUTS – Click to select an input. Settings associated with that input will also be

displayed in the window panel. If both the Video (green) and Audio (blue) boxes are selected (X), the audio and video will switch together (Audio Follow); if not, they may be switched separately (Breakaway).

The Video type (example VIDLD_s) and Audio level (example +14 dB) are displayed to the right of the buttons.

AUDIO MUTE – This button mutes the Audio temporarily. DISPLAY POWER – This button is the same as the Display Power button on the

System 4xi front panel. If available, it turns the display (projector) off or on.

DISPLAY MUTE – This button, if

available, turns the display (picture) off temporarily.

FREEZE – Freeze Frame Mode

is active if this LED is on. While in this mode, the output will be a single frame of video until the Freeze button is pressed.

Chapter 5 • Using Windows® Control Software

PICTURE CONTROLS – Depending upon the model of your System 4xi, there are

three, four or five controls that correspond to the Picture Controls on the System 4xi front panel. Each control is clearly marked and has a “nudge” button for increasing and another for decreasing the setting. (These controls are also available through the Configure Video pull-down menu.

_______ The actual window panel controls will depend upon your System 4xi model, as

well as the projector, or display device that is connected to it.

This section shows examples of System 4xi panels when in Executive Mode. After setting up the audio and video controls, the System 4xi may be put in Executive Mode. This simplifies switcher operation by disabling most of the audio and video setup controls and not displaying them. This mode also “locks” configuration settings by not allowing access to them.

Figure 5-6. Example of a System 4

Enter Executive Mode from the Configure Menu; leave by clicking on the Normal button.

Executive Mode takes up less space on the computer screen, allowing space for other applications.

Programming the System 4xi Series Switchers

This section covers the commands for a host to setup and control a System 4xi series switcher through the RS-232 port. The material included covers the System 4LDxi and the System 4LQxi switchers. Commands or parameters that apply to specific models will be pointed out, otherwise, all references will simply say “System 4xi ”.

RS-232 Connections

A standard RS-232 port is available on the back of the System 4xi for use by a host system. The connections are as follows:

Figure A-1. The RS-232, 9-pin D Connector on the Rear Panel

_______ Rx2 and Tx2 are used to communicate with a slave switcher (do not connect to

RS-232 Protocol

Program Instruction Levels

or use these pins)

The default protocol is: 9600 baud, 8-bits, no parity, 1 stop bit and no flow-control. The baud rate can be changed through a front panel menu. (See Chapter 3.)

The System 4xi recognizes any character that comes in on the RS-232 port as a possible command. Commands can be from either of two groups, or instruction sets. They are as follows:

1. The Simple Instruction Set can be any ASCII character that is recognized by the System 4xi as a command. For this set, there are no codes required to say that a command is coming, or that a command has ended. Simple commands could come from a terminal, or any other controlling device. After the System 4xi gets the command, it will execute it and send an appropriate response to the controlling device.

2. The Advanced Instruction Set consists of more complex instruction strings. Advanced instructions are used when a complete command cannot be defined within one character. Each instruction string must begin with an Escape code (ESC) and end with an End Of Transmission code (EOT). Advanced commands could come from any controlling device capable of composing a command and sending it as a string. The System 4xi will execute any legal command string and send a response string back to the host.

Because of this “open recognition”, commands from the two instruction sets can be intermixed. Both instruction sets are listed and defined on pages that follow.

_______ RS-232 control can also be established from a computer using the Windows®

operating system and Extron’s software. This is covered separately in Chapter 5.

System 4xi -Initiated Messages

When AC power is initially applied to the System 4xi, the following System 4xi- initiated messages (underlined) are sent to the Host:

Appendix A • RS-232 Programmer’s Guide

* This message will vary depending on the System 4

When the Main power from the front panel is applied to the System 4xi, the following System 4xi-initiated messages are sent to the Host:

¿SYS x¿ (as described above) ¿Ax¿ (as described above) ¿Vx¿ (as described above)

When audio and/or video settings are changed using the front panel, the following messages or message combinations are sent to the Host:

¿Ax¿ (as described above) ¿Vx¿ (as described above)

¿Cx¿ Both video and audio settings for channel number x have been changed

When there is a change in the audio gain setting from the front panel, the following message is sent to the Host:

Appendix A • RS-232 Programmer’s Guide

Simple Instruction Set

A simple command may be a single character typed on a keyboard and does not require any special characters before or after. (i.e. It is not necessary to press “enter” from the keyboard.) However, some command characters may be followed by a “delimiter” character which further defines a specific request.

Related Terms

The following terms may be helpful in understanding information in the tables and examples that follow.

Delimiter:

A delimiter character may specify audio and not video, the switcher and not the projector, etc. For commands that have more than one character, the delimiter is always the last character for that command.

Line Feed/Carriage Return:

General – On most keyboards, pressing “enter” creates a line feed (lf) and a carriage return (cr). The screen cursor moves down one line (lf) and to the left margin (cr). This is done to prevent stringing unrelated information together. Because these are separate functions, the programmer may send them at any time, and in either sequence (lf/cr or cr/lf). Also, some applications may issue these commands at the beginning of a sequence, at the end of a sequence, or both. Each response (as seen on a terminal display) will use it in one form or another. System 4xi – The System 4xi uses lf/cr before and after each response and is symbolized as

(¿)

in examples that follow.

Discrete Command:

A “discrete” command can do only one thing. For example, if projector power is already On, sending a “discrete power on” command does nothing. See toggle.

Display, or Display Device:

“Display” refers to the video output device (projector, monitor, etc.)

Host:

Any device capable of talking to the switcher through an RS-232 port.

Space:

When writing programs, it is critical to know when to insert a space and when to leave it out. If not done correctly, the command will not work. Examples in this chapter use a dot (·) to represent a space. This should eliminate any confusion.

Switcher:

“Switcher” refers to the System 4xi or any slave inputs from other sources.

Terminal:

Any device that includes a keyboard and a display. This could be a “dumb” terminal, a “smart” terminal, a PC operating in “terminal” mode, etc.

Toggle:

A “toggle” command changes the state of the function. This can be either of two things: If the function was Off, the command turns it On; if the function was On, the command turns it Off. A toggle command character may be either upper or lower case.

A-3

Zero:

The number zero may be shown as Ø to distinguish it from the letter “O”.

The codes discussed in this section include any character that may be part of a command or part of a response. This includes delimiter characters, data characters, etc. Some functions may have more than one command. For example, Power has a “turn on”, a “turn off” and a “toggle” command.

Selecting Inputs Using Delimiters

When selecting inputs to the projector, or display (Dsp) and/or the System 4xi switcher (Sw), audio and video can be switched together (follow) or separately (breakaway). An input is selected by its ASCII number, followed by a delimiter character. The delimiter ends the command and also determines which inputs (audio/video) are affected. System 4xi delimiters are listed and explained below. There are four delimiters that affect the System 4xi. They are:

! Affects Audio & Video (Aud/Vid) for the switcher (Sw) and affects only video for the projector (Dsp/Sw) @ Affects Audio and Video (Aud/Vid) for switcher only (Sw) $ Affects Audio only (Aud) for the switcher (Sw) & Affects Video only (Vid) for both projector and switcher (Dsp/Sw)

Advanced Instruction Set

The Advanced Instruction Set uses commands that are longer than one character because they are more complex than the Simple Instructions described earlier. Advanced Instructions can be used in programs that may be stored and executed as needed.

The system sees the RS-232 information in two general categories:

However, only certain codes are used by the System 4xi.

The components of an Advanced Instruction are:

Switcher response to the command:

Appendix A • RS-232 Programmer’s Guide

If bit 7 = 0 (00h - 7Fh), this byte is an instruction. If bit 7=1 (80h - FFh), it is considered to be data, or information.

Escape Code (ESC) - to indicate the start of command Command Code - to tell the switcher what to do Subcom - Data (if required) – as many bytes as required for parameters to supplement the Command Code End Of Transmission (EOT) - to indicate the end of this command

Escape Code (ESC) - to indicate the start of a response Command Code - repeated to identify what the response is for Error Code (ERC) - to indicate no error, or what type of error Data (if required) - to give the host what was requested End Of Transmission (EOT) - to indicate the end of the response

Advanced Instruction List

Error Codes (ERC)

The command protocol is as follows:

ESC, Command1, Subcommand1.1, Subcommand1.2, etc... EOT

The commands listed here are Advanced Instructions, however, they can be intermixed with commands from the Simple Instruction Set.

Command Hex Description

CMD4 34h Select input channels (audio and video) CMD5 35h Request system status CMD6 36h Adjust settings (incremental) CMD8 38h Set up System 4xi for slave configuration CMD9 39h Configure an input channel

CMD10 3Ah Request input channel configuration CMD11 3Bh Configure system CMD12 3Ch Request system configuration

(These are command characters, because they are in the range of 00h - 7Fh.)

An ERC character is included with each response from the System 4xi. Here are the codes for the ERC character used by the System 4xi: 80h = No error 81h = Invalid channel 82h = Command not recognized (illegal command) 84h = Projector communication error 85h = Switcher is Off, cannot execute the command 8Ah = Invalid command 8Dh = Invalid parameter value (These are data characters, because they are in the range of 80h - FFh.)

Hex, Decimal and Binary Examples for Converting Range Values

1. The Audio range is C1h to FFh for -31dB to +31dB and 31dec = 1Fh. To calculate the mid-range (zero dB) add 31d to the low number.

C1h = 1100 0001bin = -31dec = low end of range 1Fh = 0001 1111bin = 31dec = half of range E0h = 1110 0000bin = 00dec = mid-range (zero) value

To set Audio to +10dB, add 10d (0Ah) to the mid-range (zero) value.

E0h = 1110 0000bin = 00dB 0Ah = 0000 1010bin = 10dec EAh = 1110 1010bin = +10dB

2. The picture control range is 81h to FFh for -63 to +63 and 63dec = 3Fh. To calculate the mid-range (zero setting) add 31dec to the low number.

81h = 1000 0001bin = -63dec = low end of range 3Fh = 0011 1111bin = 63dec = half of range C0h = 1100 0000bin = 00dec = mid-range value (zero)

To set a picture control to -10, add 53d (63d - 10d) to the low end.

81h = 1000 0001bin = -63 = low end of range 0Ah = 0011 0101bin = 53 = 63 - 10dec B6h = 1011 0110bin = -10 = new setting

_______ This is one example of how it can be done. You could also subtract 10d (0Ah)

Select Input - CMD4 (34h)

from the mid-range value.

CMD4 is for selecting video and audio input channels. The flexibility of this command is that it allows for selection of audio and video from separate channels (Breakaway mode) or from the same channel (Audio Follow).

By using a “no change” parameter it can be used to select either audio or video, without changing the other. The command can also specify System 4xi only, or System 4xi and the display device. The range of channel numbers is 1 thru 22.

Format: ESC, CMD4, Subcom4.1, Vid#, Aud#, EOT Where: ESC, CMD4 = 1Bh, 34h

Upgrading Main Controller Board Software and Battery Replacement

________ This procedure requires removing both AC power as well as the battery backup.

If your System 4xi software is version 1.3 or greater, it may not have a backup battery. For earlier versions with a battery backup, all programs stored in the System 4xi will be lost.

1. With the System 4xi cover removed and AC power disconnected, unplug the red/ black backup battery cable at the Main Controller board. If there is no backup battery, please disregard this step.

2. Be sure you are electrically grounded! Use the PLCC IC puller to remove the old Software chip. Squeeze the tool to align the hooks with the slots provided in opposite corners of chip socket U8. Insert the hooks, squeeze gently and pull the IC straight out of the socket. Set the chip aside.

3. Take the new software chip and note the location of the angled corner. Orient this to match the angled corner of the socket U8 and carefully press it into place.

4. For systems with a backup battery, please reconnect the red/black cable to the Main Controller board.
