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 # M2.1 M2.1+1 M2.
1.2. General Specifications Audio Quality Sample Rate: Dynamic Range: Frequency Resp.: THD: 48kHz 90dB 20Hz - 20kHz <0.01% at 1kHz Audio Output Type: Mode: Connection: Level: Adjust: Balanced, analog Stereo or dual mono* Pluggable euro terminals +4dB max.
1.3. Hardware Configurations 1.3.1. M2.1 Single Balanced Stereo audio channel, 10 message input selections, RS232, wall mount/table top package. Left channel balanced audio output Right channel balanced audio output Relay(Form C) Stop contact Start contacts 1 - 10 Input Common Power Connection Audio Level Adjustments, L/R Playing LED Configuration Switches RS232 Connection 1.3.2. M2.1+1 Dual Balanced Stereo audio channels, 10 message input selections each, RS232, wall mount/table top package.
2. Installation & Configuration This section provides complete instructions for mounting the M2 High Fidelity Multi-Channel Digital Audio Player on a Wall or Table. It also illustrates all interface requirements to auxiliary equipment, including inputs and outputs. Configuration switch settings are provided. 2.1. Installation Steps These are the general steps for installation. 1. Find a space on the wall or table. For table top applications, install included rubber feet.
2.2.3. Audio Level Adjust Two potentiometer to adjust playback level of the left and right channels individually. Range is continuous from -infinity to +4dBm. 2.2.4. Relay Playing relay is a Form C contact closure. This contact is activated for the length of the playing message and is released when the message ends or is stopped. The playing relay is capable of handling 1A at 24VDC or 0.25A at 110VAC, non-inductive load. Normally Closed Common Normally Open 2.2.5.
2.2.7. Config Switches 8 position DIP Switch: UP Position is OFF DOWN Position is ON 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.
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.
2.2.9. RS-232 Hardware Configuration: RS-232 serial interface for control and configuration of the M2. Port settings are 9600 baud, No Parity, 8 Bits, 1 Stop Bit. NOTE: 115.2k baud rate is a factory set option. This port is designed for communication with a local user or controller over a short reliable interface. No error detection scheme is implemented over this interface. All command characters and returned information are in ASCII format. When connected properly, the system prompt M2> will be returned.
2.4.3. CH 2, Relay: Playing relay is a Form C contact closure. This contact is activated for the length of the playing message and is released when the message ends or is stopped. The playing relay is capable of handling 1A at 24VDC or 0.25A at 110VAC, non-inductive load. Normally Closed Common Normally Open 2.4.4. CH 2, Remote Control: 12 position pluggable terminal strip. Use for remote control start of message playback and stopping messages.
2.5. M2.2 Enhanced Configuration and Features: The M2.2 offers all the configuration and features of the base system with 10 additional start inputs. Contacts 11 - 20 are located above 1 - 10. 2.5.1. Remote Control, 11 - 20: 12 position pluggable terminal strip. Use for remote control start of message playback and stopping messages.
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 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".
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 will disable message 5.
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 DDIR - Displays a file directory listing of all files in the \DAVE directory of the FLASH card. Example; DDIR DDEL - Deletes file from the \DAVE directory of the FLASH card. Syntax; DDELfilename Where; filename is the name and extension of the file you wish to delete.
DGDT - Get the Date and Time from the M2. Example; DGDG DSDT - Set the Date and Tem of the M2. Syntax; DSDSdatetime Where; datetime is entered in “mmddyyyyhhmmss” format, ie month, day, year, hours, min., sec. NOTE: MUST BE IN QUOTES Example; DSDT"01012000120000" configures the M2 for 1/1/2000 12:00.00. 4. Playing - RS-232 RS-232 playback is achieved through the RS-232 connection located on the endplate of the M2 unit. Please reference Section 2.
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.
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.
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.
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.
7. Memory Card Removal/Installation: The M2 utilizes removeable PCMCIA FLASH memory cards to store audio and configuration information. The image below illustrates how the card interfaces with the M2. The memory of the M2 is hot swappable and may be removed or installed without removing power from the system. 7.1. 1. 2. 3. 4. 7.2. Removal Unscrew the four mounting screws and remove the cover plate to expose the memory card.
