1. OVERVIEW

1.1. Features and Capabilities

The Mackenzie M2 system is the most flexible series of high fidelity, multi-channel solid state digital audio playback systems available to the industry. The M2 is backed by Mackenzie’s years of system design experience.

The M2 retrieves MPEG audio data from non-volatile PCMCIA FLASH memory, eliminating the need for battery backup, and delivers superb full bandwidth sound quality.

The M2 is offered in the following configurations:

Model # Description

M2.1 Single Balanced Stereo audio channel, 10 message

input selections, RS232, wall mount package

M2.1+1 Dual Balanced Stereo audio channels, 10 message

input selections each, RS232, wall mount package

M2.2 Single Balanced Stereo audio channel, 20 message

input selections, RS232, wall mount package

M2-RM-x M2 rack mount packaging. 1U package contains power

supply and houses up to 3 M2 modules. Must be ordered as a system, not field upgradable.

Messages are stored on PCMCIA FLASH memory cards(sold separately). Messages are randomly and instantly accessible. Dynamic Message Length (DML) technology has been incorporated in the M2 allowing each of the messages to be of different duration. DML also provides for replacement messages to be a different length than the original, maximizing memory efficiency and compatibility with future applications.

Messages are stored in MPEG I, Layer II format. Composer software allows a Windows computer to create entire programs with .WAV files then converts them to MPEG. The MPEG files then may be copied to the a PCMCIA drive on the computer or downloaded directly to the M2 over the RS232 port

Message playback is controlled by simple contact closures or by RS232 commands. Audio outputs are balanced and level is controlled via potentiometers. Form C relay connections are provided to indicate that the M2 is playing.

The M2 offers several different playback modes to accommodate different applications. Play/repeat, Play once per closure, Play while active, and Retrigger allow the user to customize input logic. Message repetition and delay between messages are user selectable as well.

The M2's small size, industrial construction and the absence of moving parts makes it ideal for automatic unattended operation, especially in harsh environmental or mobile conditions.

2.2.7. Config Switches

8 position DIP Switch:

This user adjustable dip switch is provided to allow the user to tailor the operation of the M2 to meet their demands. Note: This dip switch is read by the CPU only upon power up. Changing the

position of the dip switch while the module is powered up will have no affect on the operation of the system.

Number of Plays - 1 , 2

For applications where messages need to be repeated due to noise or for clarity. Repeating messages in this fashion eases system overhead. Global setting for all messages. When message is activated, it will play the programmed number of times.

Delay Between Plays

Messages played immediately after one another can be confusing to the listener. Allowing a delay time can make the playback easier to understand. Global setting for all messages.

UP DOWN Position is ON

Position is OFF

Play activated message one time Play activated message two times Play activated message three times Play activated message four times

One second delay between plays Five second delay between plays Ten second delay between plays Thirty second delay between plays

Play Mode

Defines playback mode of message sequences. Message sequences are comprised of message material, number of plays and delay between plays

Play Next

Enabling next message allows Start 10(Remote Control connector, Start

10) to initiate playback of next valid message sequence. First input after power on will play message 1. All operation modes are supported and other start inputs are disabled.

Memory Protect

Allows user to lock message memory so that messages may not be accidentally overwritten.

M2 User's Manual V 1.0 Revised 4/21/2003 Page 9

Page 10

2.2.8. Play Mode:

Standard Operation: A momentary contact closure causes the device to play one sequence of the message corresponding to that input. A sequence being the number of plays selected by the dip switches and the selected delay time which separates them. If a contact is maintained active, the system will continuously play that message repeatedly until the input is released at which time the system will finish the current playback sequence and then stop.

If multiple inputs are held active the system will play one sequence of the first message and then cycle through any other active messages sequentially based on the order which they were input. The message corresponding to the lower input number will have priority should multiple inputs be activated at exactly the same time.

If a momentary contact closure is provided while a message is playing and it is released prior to the ending of the message play, it will be ignored.

The system will only queue messages in this mode when inputs are activated simultaneously. If all eight simultaneous inputs are momentarily provided to the system, the device will play all eight message sequences and then stop.

Play one sequence per closure: If an activation input is maintained, the system will only play the message sequence one time. The M2 will wait for the input to go inactive for a preset amount of time before it will recognize that input for subsequent message activation. Other play activation will be serviced normally even with another input held active indefinitely.

This mode supports message queuing. Message queuing allows the user to input multiple, momentary activation's to the M2, causing each of the messages to be played in the order they were received. The queue length will be 16 messages maximum, including the message which is playing. Any activation issued once the qu eue is f illed wil l be ign ored.

A stop command will stop the message which is currently playing, and when released, the next message in queue will begin pla ying.

If multiple inputs are held active and maintained, the system will play each of them and then stop. Play while active: The M2 will be activated upon reception of a maintained input control signal.

The message will continue to play for the duration which the control signal is held active. If the input signal is removed prior to the end of the message sequence, the system will immediately abort the playback sequence.

If the input is not removed during the delay time after the last message play in the sequence, another sequence will be initiated. If the input is removed prior to the end of the delay time the message will not be replayed.

If multiple inputs are maintained active while in this mode, the system will only play the lower numbered message and then repeat.

Re-Trigger: This mode allows playing messages to be interrupted by another incoming message, or another activation of the same message. If a message is currently playing and another message activation is received, the currently playing message will be stopped and the new message will be played.

A maintained message activation will only play the sequence one time and then stop. If multiple inputs are activated at exactly the same time, only the lower numbered message will be played.

Page 14

BLD - (same function as PRI S). Build message file index. Required to activate files that are copied

to the memory card outside of the Composer process. Syntax;

BLD Example;

BLD<CR><LF> Builds message file index.

DIR - The configuration of each memory location will be displayed to the user when this command is

issued. The display will show each of the 256 available message locations with either a number preceded by a "M", a number preceded by a "D" or "XXXX".

Example; DIR<CR><LF>

If a "M" precedes the number in the location, the message is valid and available for automatic playback. If “XXXX” is in the location, the message is currently blank, and the location is available. If a “D” is in front of the message number, a message exists, but it is disabled and not available for playba ck.

LST - This command lists the commands available to control the M2.

Syntax; LST

Example; LST<CR><LF> displays a list of commands, values and descriptions.

PLY - This command is to playback messages from the M2.

Syntax; PLYmsgnumber,channel,repeat,delay

Where;

msgnumber is the message location to be played<1-255>. channel is the channel on which to play <1 or 2 or A>. Default is A for all available channels. repeat is the number of times to play the message<1-254>. Default is 1. delay is time to delay between repeats <1-60> seconds. Default is 1 second.

Example; PLY6,1,10,5<CR><LF> will play message six, out channel 1, ten times with a five second pause

between the repeats.

If no msgnumber is given, the system will play the next available message in memory. This defaults to message # 1 at power up. If no repeat is given, the system will play the message one time. If no pause is given, the system delays one second between subsequent message plays.

Repeat may not be entered without msgnumber being entered. Delay ma y not be entered without repeat being entered.

M2 User's Manual V 1.0 Revised 4/21/2003 Page 14

Page 15

PRI - Messages can be enabled or disabled using this command. Normal conditions will warrant

each message to have “1” priority meaning they are active. If a message is set for “0”, then it is considered inactive and will not be played in the sequential mode or when a PLY command is issued relating to that message number.

Syntax; PRImsgnumber,status

Where;

msgnumber is the message location<1-255> status is the priority, 1 for Enable, 0 for Disable, S for Scan.

Example; PRI5,0<CR><LF> will disable message 5.

Each message will default with a priority of 1 or enabled after it is recorded. Disabled messages are displayed with a D in front of the message number when the message directory is listed. Disabled messages cannot be played until they are enabled. Scan duplicates the function of the BLD command in that it scans the system and builds a message file index.

RST - This command causes a warm reset of the M2 system.

Example; RST<CR><LF>

SHP - This command allows the user to delete the entire contents of the memory and reset system

settings to factory default. This command will erase the entire memory and reset all of the configurable settings to those specified in the Product Specification.

Example; SHP<CR><LF>

Because of the time required to erase FLASH memory, the system may take up to 10 seconds before becoming available to receive new commands.

STP - Stop message playback

Syntax; STPchannel

Where; channel is the channel, 1 or 2 or A(M2.1+1 only), that you want to stop. Entering no channel

value or A(ALL) stops all channels from playing.

Example; STP1<CR><LF> will stop message playback on channel 1.

STS - This command toggles the display of RS-232 feedback from the M2 ON or OFF. With Status

ON, the system will send a message to the RS-232 port indicting that the particular message has stopped. This status may be used to control other systems based on the mode of the M2.

Example; STSvalue<CR><LF>

M2 User's Manual V 1.0 Revised 4/21/2003 Page 15

Page 16

Where; value is 0 for off and 1 for on

SYS - This is a diagnostics feature for testing purposes only. Certain status information from the

M2 unit will be output to the user when this command is entered. Example;

SYS<CR><LF>

DDIR - Displays a file directory listing of all files in the \DAVE directory of the FLASH card.

Example; DDIR<CR><LF>

1.MPG. M2 will confirm request then return to the M2> prompt. Message LED will

remain ON during playback. Step 5 - Input STP then a carriage return and line feed(<CR><LF>) to stop playback and return

to idle mode - or - allow message to play to end at which point, system will return to

idle mode.

This process is valid for any message(1 - 255) that has a corresponding .MPG file on the memory card. M2 will report an error for a message request which does not have a corresponding .MPG file. Play relay contact will be active for the duration of play sequence.

5. Playing - Remote Contact

Remote Control playback is achieved through the remote control connections located on the endplate of the M2 unit. Please reference Section 2.2 of this manual for additional information on available connections. Playback of message will include selected repeat and delay parameters.

Step 1 - Verify the installed PCMCIA FLASH memory card has all the M2 configuration files as

well as 1.MPG. Step 2 - Make all desired power, audio out, configuration switch and I/O connections to the unit

and power up. Unit will initiate self test and def ault to pla y mode. Step 3 - Provide a momentary signal between Remote Control Start 1 input and the Common

input. M2 should play message 1.MPG. Message LED will remain ON during playback. Step 4 - Provide a momentary signal to the Remote Control Stop and the Common input to stop

playback and return to idle mode - or - allow message to play to end at which point,

system will return to idle mode.

This process is valid for any Start input which has a corresponding .MPG file on the memory card. M2 will ignore an input which does not have a corresponding .MPG file. Play relay contact will be active for the duration of play sequence. When playing multiple messages through queued messages or via maintained start activations, the system will drop the play relay for approximately 100mS between sequences.

6. Composer:

Composer software is a Windows 95/NT application which allows standard .WAV files to be converted to MPEG 1, Layer 2 files for playback on the M2.

6.1. Main Screen

The main screen provides the following functionality:

 Create / select / delete composers  Browse the available disk drives, including mapped drives  View the available WAV files in a folder  Drag and drop WAV files into the Snippet section for compilation into an M2 memory.  Delete / Add / Insert WAV files into the Snippet section.  Compile the Composer, which creates the MPEG files for use on an M2 system.

The following pictorial shows show basic layout and location of controls on the user interface.

6.1.1. Encoding Functions:

There are two methods to encode a composer, Export Composer and Compile Composer. When ever either of these buttons are used, the system will encode all of the Snippets which have been added or changed since the last time the composer was encoded, and store the MPEG files in the CMACData folder. The Export Composer adds the ability to provide a target drive where the MPEG files will be copied to, after they are encoded. Typically, this will be used to point to the PC Card drive where the M2 Memory card would be burned.

If the User Double Left clicks a snippet in the snippet section, the Snippet properties screen will pop-up. This screen, shown below provides certain specifics about the source WAV file and allows the user to change the format and audio quality of the MPEG file being produced.

The snippet can be played using the Media Player bar in the lower part of the dialog box. Descriptive information can be entered in the “Snippet Text” section.

After making any changes to the snippet properties, make sure to hit the “SAVE” button in the lower left hand side of the dialog box for the setting to take effect.

The “Set Default” pushbutton allows the user to set the default settings for the Encoding Quality and Output Format of the MPEG file to be produced. Every WAV file dragged into the snippet section will default to these settings. After making changes, make sure to save the settings for them to take effect.

6.1.2. Miscellaneous control functions:

The “Tools” drop down menu in the top, left hand portion of the screen provides the functions to control the screen format save mechanism settings and an “Other Settings” dialog. In the “Other Settings” section, two settings are provided: Low Priority E nc od ing and Make WAV File Copies.

M2 User's Manual V 1.0 Revised 4/21/2003 Page 20

Page 21

Low Priority Encoding: The WAV to MPEG converter requires a large amount of processor power. If the user is trying to run multiple applications checking the low priority encoding box will increase the amount of time to encode the files, but will allow other applications to run quicker while the encoding is taking place.

Make WAV File Copies: When the user drags WAV files into the snippet section, the M2 Composer software uses the WAV file in the location specified to create an MPEG copy of the file for use with the M2. If the Source WAV file is moved, or deleted, the composer will not be able to re-encode that file. Checking this box causes the system to create a numbered copy of the WAV file in the CMACData folder for backup purposes.

Toward the top of the screen, above the WAV File and folder section, is a horizontal bar which contains particular information regarding the currently selected WAV file. This information is formatted from left to right with the following data:

 File name  Size, in bytes  Duration  Format (mono or stereo)  Bits per sample

At the bottom of the screen, below the Folder and Snippet sections, is a horizontal bar which contains particular information regarding the currently selected Snippet. This information is formatted from left to right with the following data:

 File name  Encoding quality / bitrate  Duration  Format (mono or stereo)  Sample rate, in kHz

Screen settings: The available area for each section of the display can be tailored to the user’s preference. When the cursor is placed over the separating bar between each pane, the cursor will change shape allowing the user to left click the bar and drag it to what ever location is preferred.
