2. Installation & Configuration This section provides complete instructions for mounting the M3 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 potentiometers adjust playback level of the left and right channels individually. Range is continuous from -infinity to +3dBm. 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.
2.2.7. Configuration 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 M3 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 M3. Port settings are 115.2k baud, No Parity, 8 Bits, 1 Stop Bit. NOTE: 9.6k 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 M3> will be returned.
2.4.2. CH 2, Audio Level Adjust: Two potentiometer to adjust playback level of the left and right channels individually. Range is continuous from -infinity to +4dBm. 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.
2.5. M3.2 Enhanced Configuration and Features: The M3.2 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.
4. RS-232 Commands: Extended control of the M3 system can be performed over the RS232 port. This port can be used to control the device from a Programmable Logic Controller (PLC), or manually from a Terminal style program, such as Hyperterminal. The protocol is human readable, allowing a technician to enter simple control commands. This port provides playback control, diagnostics, system setting adjustments, and downloading of new messages into the memory card of the M3 system.
4.5. RS232 Command Syntax 4.5.1. Play snippet command Command code: PLY(I) Command body: , , , “a”, snippet #, where can range from 1 to 9,999 decimal “b”, channel #, acceptable values: 1, 2, 3 (3=Both CH) “c”, # of plays, acceptable values: 1-99 “d”, pause amount, acceptable values: 0 to +/-99 (+, or nothing = seconds, - = minutes) This plays an individual snippet from memory. This command will play snippet , through channel , times, with a pause between plays.
4.5.3. System reset command Command code: RST Command body: None Will reset the entire system, ceasing any current activity of the M3 system and initiate a warm boot sequence. Any playing messages will be stopped immediately. Example: RST , will initiate the system reset function Command response: 4.5.4. Initiate Upload File (Read from M3) Command code: ULD Command body: Files can be read from the memory card.
4.5.7. RS232 Serial Port Speed Command code: SPD Command body: , baud rate setting, acceptable values: 0 to 6 (Default: 4) The speed of the RS232 port may need to be configured for different controllers. This command provides control of this feature.
4.5.10. Format SD Card and Restore Factory Defaults Command code: SHP Command body: none This command will format the entire SD Card, completely erasing the contents of the card. All audio files, configuration files, and all other files will be permanently and irrevocably deleted.

Available information which will be supported by this command will be: The response will be formatted in the following way: Manufacturer of unit Model of unit M3 app version Date of app code Current Date and Time
4.5.17. Display Message Listing Command code: DIR Command body: None Displays the list of messages programmed on the internal memory card: The response will be formatted in the following way: 1 11 21 dd 2 12 22 dd 3 13 23 33 4 14 24 34 5 15 25 35 6 16 26 36 7 17 27 37 8 18 xx 38 9 19 xx 39 10 20 30 40 If a message number doesn’t exist, the location will be marked with “x”s. If a message has been disabled the location will be marked with “d”s.
4.5.20. Set Bass Amount Command code: BAS Command body: , “a”, Bass setting in dB, acceptable values: 0 – +/-10 “b”, channel number, acceptable values: 1 – 2 Default: 0 Default: 1 The bass for the audio playback is set with this command.
