M-series User Manual – Overview

1.0 M-series Hardware

The Intelix M-series matrix mixer is an RS232 controlled audio matrix slave device.

The audio matrix is a fully controllable crosspoint matrix. At every crosspoint the user can independently specify variables such as target value, ramp time, slew rate etc. M-series matrices are available in sizes ranging from 8 X 8 to 128 X 128 in increments of 8 inputs or 8 outputs

Control of the M-series is accomplished either with the supplied Intelix software or via an external RS-232 controller. Common RS-232 commands and protocol are covered in later sections of this manual. See

section 1 1.0

Fig. 1. This drawing shows the M-series matrix with the main sections of the rear panel, and basic internal board layout.

1.1 M-series Internal hardware

This drawing shows the layout of the basic matrix 8 X 8 card. Shown are the input and output VCA rows and columns. The heavy black line shows a typical audio route, input four to output three. This route is affected by the setting to the parameters of the input, the crosspoint and the output VCAs.

1.2 Audio Input/Output

1.2.1 Audio Input

Any line-level audio input can be routed and mixed using the MZP . The inputs are connected to the Matrix via removable screw-terminal (“Phoenix-type”) plug receptacles. The audio input to the Matrix can be either electronically balanced (impedance of 20 KΩ) or you can unbalanced it to 10 KΩ. The correct way to unbalance the input is to “float” it, i.e. leave the unused pin open, as shown below . (For other methods of wiring Inputs see the following page.)

Fig. 9. These drawings show how balanced and unbalanced inputs should be connected to the Matrix audio inputs.

Matrix Input Connector

1.2.2 Audio Output

Audio output devices are connected to the Matrix via removable screw-terminal (“Phoenix-type”) plug receptacles. The audio output from the Matrix is electronically balanced (impedance of 440 Ω), but it can be unbalanced (impedance of 220 Ω) by the user. The correct way to unbalance the output is to tie the negative leg to ground, as shown below .

The Matrix is designed to give a 6 dB boost (which compensates for the signal-level loss due to unbalancing) to a signal unbalanced in this way . Therefor e this method of unbalancing is preferable to floating

one side of the pair of leads to unbalance it.

1.3 Recommended Input Connections

Any line-level audio input can be mixed and routed using the Matrix. The inputs are connected to the Matrix via screw-terminal (“Phoenix-type”) plug receptacles. The audio input to the Matrix can be either electronically balanced (impedance of 20KΩ), or it can be unbalanced (impedance of 10KΩ) by the user. The connection configurations shown below are all possible. Their properties are described so that the user may chose the one that will work best for a particular input.

Fig. 22. This is the polarity of the Phoenix connector viewed removed from Matrix chassis.

Fig. 23. These drawing show the best ways to connect various types of audio inputs to the Matrix Phoenix input connectors.

1.4 DC Control

1.4.1 Binary Inputs

Up to eight (8) dry contact closure devices can be connected to the Matrix via a DB25 receptacle ( ) on the rear of the Matrix. Using the Matrix, such switches or other “on-off” devices can be read by any device connected to the RS-232 port ( ). This includes show control systems, lighting controllers, audio/video editing systems etc. T o facilitate the wiring of devices to the the DB25 connector Intelix makes a 25 pin conversion cable (CPT-3 or CPT-6), which plugs into the DB25 on one end and terminates in 25 numbered bare wires at the other end. The function of the DC control devices depends on the settings of the eight DIP switches (

the System software.

Fig.13. The following drawing shows how to wire the binary inputs to the DB25 connector .

) adjacent to the DB25 receptacle. The function of these switches depends upon

Note: pins 14-20 are internally grounded

Examples of binary inputs which can be connected to the Matrix include:

♦ any dry contact closure, such as a switch or relay contact ♦any open collector device ♦any 0-5 V logic output (Do not exceed +5 VDC.)

M-series User Manual – Overview

1.4.2 Binary Outputs

Up to eight (8) logic on-off control devices can be connected to the Matrix via a DB25 receptacle ( ) on the rear of the Matrix. Any device that can send RS-232 signals and is connected to the RS-232 com port ( ) can control these outputs via the Matrix. Such devices include PCs and systems (lighting controllers, audio/video editing systems). The function of the DC control devices depends on the settings of the eight DIP switches (

) adjacent to the DB25 receptacle. The function of these switches depends upon the

System software or control commands.

Examples of binary outputs which can be connected to the Matrix include:

♦ LEDs, ♦ lamps, ♦ relay coils ♦ solenoids

This drawing shows how to wire the binary inputs to the DB25 connector . Note: pins 14-20 are internally grounded.

This drawing shows the equivalent output circuit on pins 9-13 and 21-23. The circuit to pin 24 is shown. This is the point to connect an external supply to the flyback diodes.

Notes: 1) pins 9-13 and 21-23 are internally connected to open collector drivers, up to

100 milliamp sink.

2) pin 24 can be used to connect an external DC supply (50 V maximum) to the internal flyback diodes.

3) pin 25 is connected to an internal +5 Volt power supply (500 milliamps).

4) resistor values depend upon desired LED intensity (typ. 470 Ω with internal supply).

3.0 Connecting the Control PC to the M-series

Before you can program your M-series matrix mixer, you need to have a personal computer (desktop or laptop) capable of running the M-series program. Y our computer must meet these requirements:

√ PC computer (Pentium 133MHz and 32M RAM or better) with a CD ROM drive √ Windows® ‘95 or later , or NT √ Serial port connected to RS232 connector on Matrix Mixer √ a null modem cable

The connection between the M-series matrix mixer and your control PC is made with a “null modem” cable with a DB-9 connector on the matrix end as shown below . The wiring diagram for a null modem cable is at the bottom of the page. The drawing you use will depend on the connector on your PC. Most PCs have either a DB-9 or a DB-25 on the serial port. The cable wiring for both connectors are shown. Note: Some devices require that Clear to Send and Ready to send (pins 7 and 8) be tied together .

3.1 DIP Switches

There are eight DIP switches on the rear panel of the Matrix (see drawing below). For all DIP switches, the “up” position indicates the “on” condition, and the “down” position the “off” condition. The function of these switches is shown below .

DIP switches 5 and 6 allow the RS-232 baud rate to be fixed at one of three values: 9600, 19200 or

38400. The Windows M-series software does not support 38400 baud. But that speed can be used by AMX, Crestron and custom controllers.

DIP switch 7 allows the RS-232 checksum and “escape” byte to be toggled on or off. These should be turned off in installations which include a permanent RS-232 controller, such as AMX, Crestron or custom PC program. The RS-232 checksum and escape byte should be turned on in installations where the RS232 communication may be hindered because of cable length (greater than 50 feet) or lack of shielding from external electronic noise.

Note: After changing any DIP switches, you must resest the matrix by pressing the

reset button on the rear panel. Changes will not take place unless you reset the matrix.

When you select a preset name or number from this pick list. The currently displayed preset is immediately copied into the selected preset.

5.5.6.2 Copy From Live

Pressing this button causes the current live crosspoint values to be copied into the currently displayed preset.

5.5.7 Goto/Take Preset

This button causes the selected (displayed) preset to become the active audio setup. The preset will take effect at the crossfade time defined for that preset. Note that this button is only enabled when you are connected to a physical matrix.

5.5.8 All No Change/All Off/All On

These three buttons make it easy to make global changes to all crosspoints in a preset. Each causes the named effect: Changes all crosspoints to either off (-100dB), to on (0dB) or to the no change state. The no change state means that the crosspoint so marked will not be affected by invoking that preset. It will maintain its existing level. These functions speed up the process of creating new presets from existing ones.

5.5.9 Crosspoint Preview

The crosspoint preview turns on a feature that allows to quickly examine the parameters of a crosspoint. With this option checked, place the cursor over the crosspoint to be examined. A tool tip flyout will appear listing the critical parameters of the crosspoint.

7.4.2 Upload/Download Item

This screen allowing reading from the M-series, writing to the M-series, and communication setup.

7.4.2.1 Read Data from the M-series

This item allows the user to load the currently open file with the data from an M-series hooked up to the PC. For this option to work, the PC must have already established communication with the M-series. After communication is established, the M-series will transfer all its programming to the PC. The data will be stored in whatever file is open when the “M-series device to PC” command is issued. This can be an existing file or a new one, as the user wishes. A typical use of upload is to modify an existing M-series application. The user would transfer the file to the PC; make the modification, and use “PC to M-series device” (described below) to send the new configuration back to the M-series.

7.4.2.2 Write Data to the M-series

This item allows the user to transfer the current file on the PC to the M-series connected to the PC. After establishing communication between the PC and the M-series, the PC will send the currently open file to the M-series, which will store it in its local memory . After transfer, the M-series can be put in discovery mode and configured to run the new program. A typical use of PC to M-series device is to send a new design to the M-series.

7.4.2.3 Reset the Matrix Mixer

Clicking this button takes you to a screen from which you can reset the matrix with memory clear, reset the matrix without memory clear or cancel.

that the password is now enabled. This function is disabled when the password is enabled. This prevents a casual user from discovering or altering the password.

7.4.3 Communication Icons

All screens carry a communication icon in the lower left corner. The icon in the lower left corner will indicate the current state of communication. There are three communication icons:

This icon indicates that the PC is not attempting to communicate with a matrix mixer. In this mode you can create new files and design systems for later transfer to a matrix. In PC alone mode some functions may be disabled.

This icon indicates correct communication between the PC and the M-series.

This icon indicates a communication failure. Common causes are loss of matrix power, incorrect communication port selected, incorrect baud rate, or cabling errors.

7.5 The Diagnostic Menu

M-series User Manual – Windows Reference

7.5.1 Are You There

A clock in the M-series software periodically (every three seconds) sends a message (Are Y ou There) to the matrix. This feature allows the software to continually verify the correct communication between the software and the matrix hardware. When the correct Acknowledgment message (I Am Here) is received, the software refreshes the communication OK icon in the lower left of the window . If the I Am Here message is not received, the software assumes a communication failure has occurred and displays the broken link icon. Normally , the Are Y ou There item should remain active (checked). However when you are doing diagnostic troubleshooting using the T est manager, you may find that the Are Y ou There messages are filling up the communication buffer . In this case, simply uncheck the Are Y ou There item for as long as you use the message buffer , then turn it back on.

shooting problems with the matrix hardware software or application. It contains all communication setup control, and manual RS232 messaging capability .

7.5.2.1 Comm Port

The port you select from the comm port picklist must be present in your system and unused by any other peripheral in your system. If you choose a nonexistent or in-use port, a warning will appear.

7.5.2.2 Use Escape and Checksum

If your controller allows it, using escape and checksum can minimize the error rate over your communication link. If your controller does not allow the use of escape and checksum, uncheck this item.

7.5.2.3 Baud Rate

There are three available baud rates: 9600,19,200 and 38400. Choose whichever rate best suits your system. The rate you choose must be matched by the DIP switches on the back of the M-series. See

section 3.1 for DIP switch details).

7.5.2.4 Open Comm Port

This button activates the communication port you have selected. T o begin communication with the M-series you must open the port. If your settings selections have been correct, the communication icon in the lower left of the screen will change to OK; if the M-series does not respond the icon will show the broken link.

7.5.2.5 Close Comm Port

No settings can be altered while the communication port is open. If you need to change any settings to the port, you must first close it. Click the “Close port” button, make the changes and click “Open port”. Be sure to recheck the communication icon to ensure that communication is correctly established.

7.6.4 Reset Item

Selecting the reset item causes the Designer Software to issue a Class 0 ID 13 message with a 0 parameter . This is a reset command with a preserve memory parameter. This restarts the embedded matrix application code and is useful if the matrix enters a bad state or is caught in a loop. This command has exactly the same effect as pressing the reset button on the matrix rear panel.

7.6.5 Clear Memory Item

Selecting the clear memory item causes the Designer Software to issue a Class 0 ID 13 message with a 1 parameter. This is a reset command with a clear memory parameter . Y ou will be prompted to ensure that you don’t clear memory by accident. This message deletes the contents of all internal memory and causes the loss of all program information and internal variables. Before using this command you should backup your matrix program. After issuing the clear memory command you must reload the program to the matrix using the upload screen (Installation -> Upload/Download).

7.6.6 The Live Crosspoint Screen

The live crosspoint screen allows you to alter the routing and audio parameters of the audio signals in the system.

7.6.6.1 Changing Crosspoint V alues

T o change an audio level at a crosspoint, click on the crosspoint. A pair of up/down arrows and a text box appears. Either use the up/down arrows to scroll to the desired value or type the new value directly in the text box and press Enter. Doubleclicking the crosspoint toggles it between full of f and the value in the “set global” box.

7.6.6.2 Changing Source/Output Names

This screen allows the alteration of the names of both audio sources and audio outputs. T o change a name, click on it, type the new name and press Enter .

7.6.6.3 View

There are four view options. They determine how the crosspoint values are displayed. They include:

Percent: Displays values in percent of full volume. Range is 0%-100% dB: Displays values in dB. Range is 0 dB (full on) to -100 dB (full off) Note: In dB view

RS232 V alues: displays values as RS232 values from 0 (full off) to 255 (full on) Horizontal bars: displays values as a bar graph set horizontally in the crosspoint cell.

7.6.6.4 Source/Output V olume

The source column and output rows can be optionally displayed. These crosspoints are used when changing the audio levels of an entire row or column of the matrix.

T o see the detailed flow chart of a particular crosspoint or i/o VCA, left click to select it, then right click on it a screen like the one below appears.

7.6.6.8.1 T arget V olume variable

This is the level to which the crosspoint will go after all ramping slewing and curving operations are complete. It can be changed by dragging the slider or by direct text entry in the target volume box.

7.6.6.8.2 Ramp Time V ariable

Ramp time is time a crosspoint takes to reach its target value when it becomes active. Ramp time can be changed by clicking on the value, then using the up/down arrows or direct text entry to set the value. Ramp time is a value between 0 seconds and 30 seconds. For instantaneous change, set the ramp time to 0.

7.6.6.8.3 Slew Rate V ariable

Slew rate is a rate of change expressed in steps per 128 milliseconds. Slew rate can range from 0 to 32640. The advantage to using slew instead of ramp is that the volume being slewed rises at a steady rate that is independent of the distance traversed by the slew .

7.6.6.8.4 Mute variable

Clicking on the mute switch will toggle it on/off. The audio level is maintained so that when a crosspoint is unmuted it returns to the value it had before muting.

After you click the button, you will see the slider, the graph and the crosspoint attenuation box change the new level you have set.

7.6.6.8.7 Curve variable

M-series supports two audio curves: linear and logarithmic. These curves can be used to modify the raw level values to conform more to the human ear’s response. T o select a curve, click the “Control T aper” button. The live crosspoint display graph will change to show the new curve. Note that the 50% point on the graph changes to reflect the nature of the curve. T ypically the linear taper is used when a machine will be in primary control of the crosspoint setting, since it is more easily calculable and repeatable. Log curve is most often used when a crosspoint will be primarily control by a human, since the log scale has a better resemblance to the response of the human ear.

M-series User Manual – Stereo

8.0 Stereo I/O control

Y our Intelix matrix allows a great deal of flexibility when routing and controlling stereo audio. Both inputs and outputs can be defined as mono or stereo. This gives four possible combinations of inputs and outputs:

1) Mono input to mono output

2) mono input to stereo output

3) stereo input to mono output

4) stereo input to stereo output

In cases 2 and 4, there are input and output controls that can be used to set balance, panning and “width” of the audio signals. These controls are explained below .

8.1 Input controls

There are two types of input controls: an input width control, and an input pan control. The input width control is used only for ster eo inputs, and the input pan contr ol is used only for mono inputs. Their

internal workings are explained on the following pages.

8.2 Output controls

There is one output control, the output balance control. It is used only with stereo outputs. Mono outputs have no balkance or other control. The output balance control for a stereo output distributes two inputs to two outputs, in proportion to the setting of the control value.

8.3 Stereo Control Methods

There are two major ways to control stereo functions in the matrix mixer, RS-232 control and GUI control. Each method is explained below . Both methods are exactly equivalent, that is they both activate the same hardware features in the matrix mixer. The choice of RS-232 or GUi control is strictly a matter of convrnience.

8.3.1 Setting control values with RS-232

The control values for all stereo controls ( input pan control, input width control and output balance control are set with multiple calls to a single RS-232 command: I/O Goto Pan; this is a Class 1 RS-232 message (ID 14). The I/O Goto Pan message has a single parameter “pan/width/balance”. The meaning of this parameter changes depending on the nature of the target. The matrix examines the i/o flag and i/o number to determine whether the target is an input/output and mono/stereo.

The meaning of the pan/width/balance parameter is determined as follows: if target is a mono input the meaning is pan if target is a stereo input the meaning is width if target is any output the meaning is balance

M-series User Manual – Stereo

Page 59

M-series User Manual – Stereo

8.3.2 Setting Control V alues with the GUI

Stereo control in the matrix mixer GUI live principally on two screens, the audio source screen (Main > Configuration -> Audio Sources) for input panning, and the audi outputs screen (main -> Configuration -> Audio Outputs) for output balance.

8.3.2.1 Audio Input Panning

On the audio input screen (Main -> Configuration -> Audio Sources) each input has a panning control. The panning control works differently depending on whether the input is monaural or stereo. If the input is mono, the panning control (shown below) works as a panning control, that is it distributes the input to a pair of outputs proportionally to the position of the panning slider. There are three preset buttons on the screen: Left, center and right. The range of slider values from 1-127 correspond to the RS-232 parameter values described in the RS-232 section below .

8.3.2.2 Audio Input Width

When an audio source is stereo, then the pan control on the audio source screen acts as a width control. This control has a similar appearance to the mono panning control, but its preset buttons are stereo, mono and reverse stereo, reflecting the function of a width control on a stereo input pair.The range of slider values from 1-127 correspond to the RS-232 parameter values described in the RS-232 section below .

8.3.2.3 Output balance

The output balance control is only available for stereo outputs. The output balance control distributes two inputs proportionally to the setting of the balance slider control (shown below .)The range of slider values from 1-127 correspond to the RS-232 parameter values described in the RS-232 section below .

M-series User Manual – Stereo

Page 60

M-series User Manual – Stereo

8.4 Input width control

The stereo width control is used for narrowing or reversing a stereo input signal between two stereo outputs on the matrix. The control acts like a pair of linked potentiometers; e.g. any change to the pot on one input causes a corresponding change to the other member of the stereo pair. The action of the control allow full stereo separation of the two input signals, a summed mix of the two input signals to both outputs, and a complete stereo reversal of the two inputs. The value of the pots can be set at any value between 0 and

255. The input width control is used with stereo input pairs only .

The table below shows the result of setting the input width control to a range of values. The default value of the width control is 0.

8.4.1 Input pan control

As the diagram below shows, the input pan control takes a single mono input and by use of a virtual potentiometer, distributes the input to a pair of outputs. The input control pan is used only with monaural inputs.

A value of 0 on the control will send the input entirely to T ap A, and nothing to T ap B, while a value of 255 will send the input entirely to T ap B and nothing to T ap A. A value of 127 (center) sends the input equally to T aps A and B.

The table below shows the result of setting the input pan control to a range of values. The default value for the control is 127 (centered).

9.0 RS-232 Message Protocol

9.1 RS232 Message Fields

All RS232 messages, whether they are transmitted to or from the Matrix Mixer, use the same message format. Each RS232 message contains five fields. All values are transmitted in hexadecimal format e.g. 0Ah. For an explanation of transmitting in hexadecimal, please refer to section 9.3.

RS232_ST ART

9.1.1 RS-232 Message Fields

The first field of a message is always the RS232_ST AR T byte (F Ah). The second field is a 2-byte length, transmitted most significant byte first. The value of the length field is the

number of bytes in the third field, the data field.

The third field, the data field, holds the parameters of the message e.g. (02h, 03h, 02h, 05h, F2h, 13h, 88h).

The fourth field is a one-byte checksum. The value of the checksum is the additive sum of the bytes in the first three fields, modulo 256 (the least significant byte).

For example, if the data portion (3rd field) of a message is (2, 3, 2, 5, 239, 19, 136), the length field is (0,

7). The additive sum of the first three fields is (250 + 0 + 7 + 2 + 3 + 2 + 5 + 239 + 19 + 136) = 663 = 297h. The checksum is 663 modulo 256 = 151= 97h.

length (2bytes MSB first)

data (1-n bytes)

checksum

acknowledge

The checksum feature can be turned off when necessary by setting DIP switch #7 to the down position. This is recommended to simplify programming when using Crestron or AMX controllers. See section 3.1.

The fifth field is a one-byte acknowledgment field, which is sent by the device which receives the message. The value of this field is either RS232_ACK (FCh), RS232_BUSY (FDh), or RS232_ERROR (FEh).

9.3 RS-232 Timing

After a message has been transmitted to the matrix, the matrix will respond with an RS-232_ACK byte after a delay of 2 milliseconds. If the sent message requires the matrix to return a reply message, the start of the reply message will begin 1-20 milliseconds after the RS-232_ACK byte. The exact amount of time is variable depending on the nature of the reply message. These times are independent of baud rate. T o avoid collisions with reply messages, Intelix recommends that your RS-232 controller insert a delay of approximately 10 milliseconds after messages which do not generate a reply message, and 100 milliseconds between messages which do.

9.3 Hexadecimal T ransmission

The Intelix Matrix Mixer must receive all message in hexadecimal number code. If messages are transmitted in decimal or ASCII codes, they will fail to work.

Hexadecimal is a base 16 number code that uses numerals 0-10 and letters A, B, C, D, E, F . On the next page is a conversion table from decimal numbers to hexadecimal. In this document hex numbers are represented in the form “xxh”, where xx are the two hex characters.

9.3.1 Commercial controllers

Most commercial controllers require the use of special codes to represent hex numbers for transmission. For example, Crestron controllers require the sequence “\xnn” where nn is the hex byte to be sent.

9.3.2 ASCII values

Because computers deal only with numbers, letters must be assigned a numeric code. This code is called ASCII. When you send commands to the Intelix Matrix Mixer, there is one and only one case when you use ASCII codes. That case is when you send names. Whenever a name field appears in an example in this manual, the example is enclosed in quotation marks. Any other use of ASCII values will cause the command to fail.

For example the command Set Matrix Mixer Name uses as an example name field “Emmanual Lutheran Church”. The quotes indicate that this data should be sent as ASCII values. T o do this use an ASCII table to obtain the hex value for each character, and transmit these values.

Never transmit the quotation marks.

9.3.2.1 ASCII values of the alphabet.

This is not a complete ASCII table since it does not contain codes for numbers, punctuation or special characters.

A = 41h B = 42h C = 43h D = 44h E = 45h F = 46h G = 47h H = 48h I = 49h

9.5 Byte Escape Sequence

If a byte in the length, data, or checksum fields falls within the range 240h through 255h inclusive, an escape sequence is used to transmit the value, since those single byte values are reserved. The value is translated by the sending device into two bytes: the RS232_ESCAPE byte (240) itself, followed by the difference between the value and the RS232_ESCAPE byte.

value => RS232_ESCAPE, (value - RS232_ESCAPE)

These two bytes are transmitted instead of the single, large-value byte. The receiving device converts the two bytes back into the original single byte value through simple addition. These operations do not affect the values of the length or checksum fields.

Note: The escape sequence feature can be disabled if necessary, by putting DIP switch #7 in the down position. This is recommended when using Crestron or AMX controllers, since it simplifies program-

ming. See section 9.6.

In the following example, the data field of a message is (2, 3, 3, 6, 255). The byte 255 must be “escaped” into the RS232_ESCAPE byte (240) followed by the difference between 255 and RS232_ESCAPE (255

- 240 = 15 = 0Fh). The bytes actually transmitted are:

Since the second byte of an escape sequence must fall within the range 0 through 15 inclusive, any second byte outside of that range indicates that a transmission error has occurred, and the message should be acknowledged by the receiver with RS232_ERROR and ignored.

9.6 DIP Switches

DIP switches 5 and 6 allow the RS-232 baud rate to be fixed at one of three values: 9600, 19200 or

38400. The M-series supports 38400 at the embedded level and that speed can be used for Crestron and AMX programming, but since Windows® does not support that rate, the M-series GUI cannot be run at

38400.

DIP switch 7 allows the RS-232 checksum and “escape” byte to be toggled on or off. These should be turned off in installations which include a permanent RS-232 controller , such as AMX, Crestron or custom PC program. This greatly simplifies coding (and decoding) the RS-232 messages. The RS-232 checksum and escape byte should be turned on in installations where the RS-232 communication may be hindered because of cable length (greater than 50 feet) or shielding from external electronic noise.

Note: After changing any DIP switches, you must resest the matrix by pressing the

reset button on the rear panel. Changes will not take place unless you reset the matrix.

9.7 Introduction to using the RS-232 Commands

This section introduces three RS-232 commands that are needed to begin programming the M-series. The commands are chosen to get you started programming the Intelix matrix. T wo of the three commands establish communication, and the third exerts control over a chosen audio crosspoint. After these three commands are usable you should be able to use the rest of this manual to implement your application.

1) Are Y ou Ther e: This command is sent by the controller to check for the existence of a matrix. If the matrix receives this message it replies with an I Am Here message.

2) I Am Here: This message is sent by the matrix as a response to the receipt of an Are Y ou Ther e message. The matrix sends an I Am Here message whenever it is powered up or reset. This fact can be used as a diagnostic tool when troubleshooting communication, since the matrix can be relied upon to send the I Am Here message when reset.

3) Set Current V alue: This message sets the attenuation level of an audio crosspoint, and demonstrates control over the audio matrix after communication has been established.

9.7.1 Are You There

Shown below is the contents of the Are Y ou Ther e message. The format of the message is explained in section 9.1. The message has no parameters, the length is 2 bytes (1 byte for class, 1 byte for message ID). The checksum is the sum of all fields: F Ah + 2h = FCh.

Since FCh is greater than the RS232 _ESCAPE value of 240, the checksum is “escaped” into 2 bytes (F0h, 0Ch). The escape byte does not effect the length field. The escape process is explained in section 9.5. Transmitting this message consists of sending the following string of 7 bytes: F Ah, 00h, 02h, 00h, 00h, F0h, 0Ch.

00h 02h

00h

F0h 0Ch

9.7.2 I Am Here

Shown below is the contents of the I Am Here message. This message is sent by the matrix in

response to an Are Y ou Ther e message. This message is sent whenever the matrix is powered up or reset.

The format of the message is explained in section 9.1. The message has no parameters, the length is 2 bytes (1 byte for class, 1 byte for message ID). The checksum is the sum of all fields: F Ah + 2h + 1h = FDh. The checksum will be escaped when transmitted by the matrix. Receiving this message consists of recognizing the following string of 7 bytes: F Ah, 00h, 02h, 00h, 01h, F0h, 0Dh.

00h 02h

00h 01h

F0h, 0Dh

M-series User’s Manual — RS232 Introduction

9.7.3 Set Current Value

The Set Current V alue message allows direct control over the attenuation at a single crosspoint.

T o use this message as a control test, select a crosspoint to be set and encode it in the input output pair. The example below sets the current value of the crosspoint at input 2 and output 5. The value to which the current value is set is encoded in the current value parameter. This value can be any value from 0 (full of f) to 255 (full on). The example below sets the crosspoint to 255. Since 255 is hex FF the value is escaped into two bytes F0h, 0Fh. Sending this message consists of transmitting the following ten bytes: F Ah, 00h, 05h, 02h, 0Dh, 02h, 05h, F0h, 0Fh, and 15h.

When this message is properly received by the matrix, the current value will be immediately affected, since this command bypasses ramp time and slew rate. Y ou should immediately hear the change in the level of the crosspoint. Be sure that your audio source, amplifiers and speakers are all powered and working.

Action Definitions

Each message will be marked with one of the following icons:

The Matrix Mixer contains sophisticated audio crosspoints, in that each crosspoint contains a number of parameters (fields), which together define the behavior of the audio signal of the crosspoint. The crosspoint messages process data associated with individual audio crosspoints within the audio matrix. The coordinates of an individual audio crosspoint are of the form [input , output ]. The coordinate values are integral (1-128 inclusive).

Ramp Times and Slew Rates

The matrix has control over the rate at which a crosspoint changes value. This rate is expressed in two ways, as a time (ramp time), and as a rate of change (slew rate)

Ramp Time

Ramp time is expressed in units of milliseconds (1/1000 of a second). You can set ramp times to any value from 0 -30,000. This corresponds to a range of ramp times from 0 to 30 seconds. The ramping operation begins as soon as a target value is received. During the ramping time, the output being ramped rises or falls steadily in volume at a fixed rate. The rate of which is dependent on the distance being traversed by the ramp.

Calculating a ramp time:

The ramp time is a 2 byte hexadecimal number. To calculate a ramp time multiply the number of seconds you want the ramp to take by 1000, and convert the result to hexadecimal. This number is the value transmitted to the matrix.

Ramp time example: You wish audio to ramp between states in 5 seconds.

Multiply by 1000, 5 * 1000 = 5000. Convert the number to hexadecimal. 5000 -> 1388h. Use the result 1388 in the ramp time command. The high byte is 13h and the low byte is 88h.

Slew Rate

The inverse of ramp time is slew rate which is expressed in units of steps/128

milliseconds. The slew rate determines how fast volume changes will take place. Regardless of the current or target volume levels, any change in output volume will take place at the slew rate. The advantage of using slew rate instead of ramp time, is that the volume of the output being slewed rises at a steady rate that is independent of the distance traversed by the slew.

Calculating a slew rate:

The slew rate is a 2 byte hexadecimal number. You calculate a slew rate based on how fast in milliseconds (.001 second) you want the volume to go from full off to full on. This number (the FRC for full range change) will be in the range 1-32,640. It sets the rate at which all audio changes (not just full off to full on). The smaller the FRC time time, the faster the volumes will change. Typical FRC time’s are in the neighborhood of 5000 (a full range change time of 5 seconds). For a fast rate of change the FRC time should be small, e.g. in the range of 1000. For a slow rate of change the FRC time should be around 10,000. Your chosen FRC time is then used to calculate the actual slew rate value as follows:

Slew Rate = 32,640 ÷ FRC time

Slew rate examples:

1) You want audio to slew at a rate set by an FRC time of 6000 (a full range change of 6 seconds). Use the formula above with 6000 in place of FRC: 32640 ÷ 6000 = 5.44. The slew rate to program is 5. This number must be transmitted as a 2 byte hex number. The high byte is 00h and the low byte is 05h. When these two bytes are transmitted as slew rate parameters, the outputs will slew at the desired rate.

2) You want a fast slew. Select a full range change value of 2 seconds (FRC time =

2000). 32640 ÷ 2000 = 16. The two bytes of the slew rate are 00h and 10h.

3) A very fast slew is FRC time = 100 (.1 seconds). the two bytes are 01h and 46h. This is useful for “rounding off the corners” of audio changes.

Page 96

M-series RS232 Programming — Crosspoint Messages (Class 2)

4) You want a slow slew rate. Select an FRC time of 12000 (a full range change of 12 seconds). Using the formula you obtain: 32640 ÷ 12000 = 2.72. Use 3. The high byte is 00h and the low byte is 03h.

5) You want a very slow slew rate. Select a slew rate of 1. The two bytes are 00h and 01h. This corresponds to an FRC time of 32 seconds.

Conversions of ramp times and slew rates

Ramp times and slew rates are transmitted to and from the matrix mixer as a pair of hexidecimal bytes. The following section shows how to convert to and from transmission values and decimal numbers. The pair of bytes is always transmitted and received most significant byte first.

Convert from a known decimal value to a hex transmission value:

To convert a desired decimal value (N) to a 2-byte value to transmit to the matrix mixer:

1) N ÷ 256

2) The integer part of the result from step 1 is the most significant byte of the 2-byte result.

3) The remainder from step 1 is the least significant byte.

4) Convert the two bytes to hexidecimal.

5) The most significant byte is transmitted first.

Example1:

You wish to transmit the slew rate 7: 7 ÷ 256 = 0 with a remainder of 7. The two hexidecimal bytes to transmit are 00h and 07h. Example 2: You wish to transmit the ramp time 20,000: 20,000 ÷ 256 = 78 with a remainder of 32. Converting 78 and 32 to dexidecimal gives: 4Eh and 20h.

Convert from a two byte transmission value to a decimal value:

1) Convert the most significant byte from hex to decimal and multiply by 256.

2) Convert the least significant byte from hex to decimal and add it to the result of step 1.

Example 1:

You receive the two hex bytes 00h and 09h: 00 * 256 = 0. 0 + 9 = 9. The value represented is 9. Example 2: You receive the bytes 41h and 21h: 41h => 65d; 65 *256 = 16640. 21h => 33d; 16640 +33 = 16673. The transmitted value was 16673.
