INTRODUCTION

1.1 Introduction

The Australian Monitor Installation Series DMA-1 digital message announcer is a compact yet highly featured digital playback device. Utilizing an SD card digital storage format the DMA1 delivers high quality stereo audio in an MP3 format. Messages can be played or triggered using the on-board controls, via remote switches, contact closure or via RS485 serial control. The DMA-1 also boasts an on board 20 watt per channel D class power ampliﬁ er as well as stereo inputs & outputs which allow it to be inserted in line with another BGM feed.

The DMA-1’s compact size belies the wealth of features it offers. It is a highly innovative & cost effective digital message storage & playback device that has a host of commercial applications.

1.2 What is MP3?

MP3 is an acronym for Mpeg-1 layer 3. This is an audio compression standard which eliminates sounds which the human ear cannot hear via a psycho-acoustic algorithm. The purpose of this compression is to reduce the space taken up by an audio ﬁ le while still ensuring excellent quality. The greater the compression, the less the audio quality. The right compromise, which guarantees a quality comparable to that of a Compact Disc, is 128 Kbps (thousands of bits per second) which represents the most widely used manner, and reduces the size of an uncompressed ﬁ le by 10 times.

1.3 Encoder

1.4 Decoder

Software which decompresses an MP3 audio ﬁ le in order to send it to a digital-analog converter and reconstruct the original audio signal.

1.5 Player

Hardware and software system able to read MP3 audio ﬁ les. The DMA1 is able to carry out this function.

1.6 Wave

High quality audio format (extension .wav), compatible with the tracks of normal music CD’s. CD quality music utilises a sample rate of 44.1 KHz/sec. at 16 bit in stereo, but the size of the ﬁ le is approximately about 10Mb per minute.

1.7 Audio compression in various formats

The following graphic shows the space taken up by an uncompressed audio ﬁ le of about 5 minutes (.wav) and compressed in MP3 at 128Kbps (MP3).

WAVE 51.1MB

MP3 4.6MB

Software which compresses a CD audio or wave ﬁ le in MP3. There are many programmes of this kind, and it is virtually impossible to say which is the best. Freeware software encoders suitable for various operating systems can be downloaded from the following internet site: www.mp3server.4t.com

DESCRIPTION AND CONNECTIONS

3.3 Power supply

The DMA1 may operate with the following main power adaptors: 1215VAC, 12-24VDC.

It is recommended to use the mains adaptor supplied with the device. The red POWER LED lights up when power is present.

3.4 Logic inputs

The DMA1 has eight multi-function logic inputs to control the playing of the either playlists or individual audio ﬁ les.

The pins are: 1- GND 2- IN 1 3- IN 4- IN 3 5- IN 4 6- IN 5 7- IN 6 8- IN 7 9- IN 8

In order to activate the playing of a ﬁ le, connect the desired logic input pin to GND (or the desired logic input pins when operating in binary logic).

3.5 IN/OUT 8 - input/output Vlink

Programmable logic input/output to connect two DMA1s in cascade, for synchronised management of music playlists with commercials/spots at scheduled intervals without interruptions. Vlink: 0 = in standby 1 = in play (+12V)

3.6 Serial RS485 connection

The DMA1 can be connected to an RS485 bus that can be controlled by a Crestron control system, or any other RS485 enabled control system. To enable RS485 control, (pin IN5/485A and IN6/485B), remove the cover of the DMA1 and move the relative jumpers (see para. 9.1).

3.7 Line level audio input

Line level audio input (stereo) allowing the connection of an external music source (SAT, CD, Tuner, second DMA1 etc) that is mixed with DMA1 generated audio. This functionality allows the mixing of a music source with scheduled commercials or spot announcements.

3.8 Line level audio output

Line level audio output (stereo) on extractable terminal strip.

3.9 Ampliﬁ ed audio output

Ampliﬁ ed stereo audio output (20W + 20W) for the connection of external speakers. Connect external 4/8Ω speakers to the SPK L/GND and SPK R/GND terminal strip.

It is recommended to cable the DMA1 far from power cables. The two cables that connect the speaker with the DMA1 ampliﬁ ed audio output terminals can be a potential source of interference.

PAGE 8 AMIS-DMA1 INSTALLATION & OPERATION MANUAL

CONFIGURATION FILE

4.1 What is the conﬁ guration ﬁ le?

The DMA1 is a very versatile device which can be adapted to the needs of the application in which it is used. Different applications may require adjustment of volume, tone, loudness, communication parameters and timing. The conﬁ guration ﬁ le stored in the main directory of the ﬂ ash memory, together with the audio ﬁ les, makes it possible to programme the various parameters of the DMA1.

This ﬁ le must be assigned the name conﬁ g.txt (this extension has been used so it can be modiﬁ ed by any text editor, including PocketPC text editors).

4.2 Content of the conﬁ guration ﬁ le

Each line of the conﬁ guration ﬁ le consists of:

• Mnemonic code of the parameter to be set. It always consists of our CAPITAL alphanumeric characters, and must always be at the beginning of the line. No more than one parameter is permitted on the same line

• Separating ‘=’ character. This MUST be inserted just after the mnemonic code, without any spacing or tab characters

• The relevant numerical parameter expressed as a decimal, to be inserted directly after the separation character, without any spacing or tab characters

Example: LMP3=14 LOUT=14 LLIN=14 LLI2=5 LLOU=10 LTRE=10 LBAS=10 MOMD=0

4.3 How it is managed by the DMA1

At the time the DMA1 is turned on, or when the ﬂ ash memory card is inserted, the DMA1 will start to read the main directory of the ﬂ ash memory. If the ﬁ le conﬁ g.txt is found, the DMA1 will store the conﬁ guration parameters into its own internal non-volatile memory. The parameters therefore stay in the internal memory of the DMA1 even after the device has been turned off or the ﬂ ash memory card removed. It is therefore not mandatory for the conﬁ guration ﬁ le to always be present on the ﬂ ash memory card. Once all the parameters have been read and stored to the DMA1, the conﬁ g.txt ﬁ le can be deleted.

NOTE: If it is necessary to conﬁ gure multiple DMA1s with the same conﬁ guration parameters, a single ﬂ ash memory card with the appropriate conﬁ g.txt ﬁ le can be prepared and sequentially insert this memory card into all the DMA1s to be conﬁ gured. The ﬁ nal ﬂ ash memory cards to be inserted into each DMA1 now only need to contain the MP3 audio ﬁ les.

4.4 Preparing the ﬁ le

Any ordinary text editor (like Windows Notebook) can be used to create the conﬁ g.txt ﬁ le. The ﬁ le must be saved as a pure text ﬁ le (.txt). Should other programmes be used (e.g. Microsoft Word) be careful to save the document as “text only”: otherwise control characters would be inserted which would make it impossible for the DMA1 to interpret the ﬁ le.

4.5 Storing ﬁ les in ﬂ ash memory

The conﬁ guration ﬁ le and all the MP3 audio ﬁ les can be stored to the ﬂ ash memory card via a special USB reader/writer for PC.

PAGE 9AMIS-DMA1 INSTALLATION & OPERATION MANUAL

SCHEDULED OPERATION

5.1 Introduction to timed operation

When the ﬂ ash memory card is inserted, the DMA1 will analyse its “ contents and – depending on the ﬁ les which are present – will automatically set the mode of operation.

In the presence of the PALIN.TXT ﬁ le, the DMA1 plays the sequence of MP3 ﬁ les in a cyclical emission (one hour cycles) called PALIMPSEST which are contained in the same PALIN.TXT ﬁ le.

NOTE: It is very important to start a new line of text for each event, and to separate the hours from the minutes using the (:) character.

On the same line the names of the MP3 audio ﬁ les to be used (and their sequence) must be deﬁ ned (max. 8 characters).

There are three different acceptable formats for separating multiple MP3 ﬁ lenames for each event

1. Separating character [Tab] between one MP3 and the next: E.g.: 00:10 spot01 spot02 spot03

5.2 The palimpsest ﬁ le – palin.txt

The DMA1 can manage a list of MP3s to be played according to pre-set time intervals. This list is a simple text ﬁ le (palin.txt) which contains a number of time events along with a sequence of MP3 ﬁ les to be played for each speciﬁ c time event.

There are a few simple rules on how to set the palimpsest; ﬁ rstly the time for an event must be deﬁ ned in minutes. Eg: 00:10

Once the conﬁ guration has been completed, the ﬁ le will appear similar to the following example:

00:00 SPOT04 SPOT07 00:05 SPOT09 SPOT17 00:10 SPOT11 SPOT02 00:15 SPOT01 SPOT08 SPOT03 SPOT06 SPOT05 00:20 SPOT12 SPOT03 00:25 SPOT16 SPOT17 00:30 SPOT09 SPOT10 00:35 SPOT05 SPOT11 SPOT12 SPOT13 SPOT14 00:40 SPOT02 SPOT11 00:45 SPOT04 SPOT07 00:50 SPOT02 SPOT11 00:55 SPOT09 SPOT11

2. Comma (,) between one MP3 and the next: E.g.: 00:10,spot01,spot02,spot03

3. Semicolon (;) between one MP3 and the next: E.g.: 00:10;spot01;spot02;spot03

EXAMPLE OF PALIN.TXT FILE WITH CYCLICAL EMISSION AT INTERVALS OF 5 MINUTES OF COMMERCIAL SPOTS

An example of the reading and functioning of a timetable is provided below:

00:05 SPOT05 SPOT11 SPOT12 00:11 SPOT01 SPOT07 SPOT03

In this case the DMA1 remains in standby for 5 minutes from the moment it is turned on. At the 5th minute the DMA1 fades out the external line level audio input source in order to play the 00:05 time event, composed of 5 MP3 ﬁ les.

Once the time event has ﬁ nished playing Spot05, Spot11, Spot12, Spot13 and Spot14, the DMA1 fades the external line level audio input back in. Upon reaching the 11th minute the DMA1 fades out the external line level audio input source and plays the 00:10 time event, composed of 3 MP3 ﬁ les.

PAGE 15AMIS-DMA1 INSTALLATION & OPERATION MANUAL

SCHEDULED OPERATION

IMPORTANT! When using the line level audio inputs, check

the settings of the LLIN, LLI2 and MOMD parameters inserted in the conﬁ guration ﬁ le (par. 4.6).

Programming limits:

Max. programming time permitted 1 hour (cyclic) From 00:00 to 00:59

Max. quantity of time events 60 events

Max. quantity of MP3s per time event 8 MP3 ﬁ les

Max. quantity of MP3s per palimpsest 500 MP3 ﬁ les

5.3 Mixer function

The DMA1 has an audio input for connection to external music sources, with a mixer function to mix this source with the ﬁ les played from ﬂ ash memory (see par. 8.3). At the time scheduled for delivering each time event the DMA1 fades out the external audio source from the level LLIN to the

level LLI2, according to a programmed fade time TFOU. Then the sequence of MP3 ﬁ les of the time event are played at LMP3 level, mixed with the external audio source with level LLI2.

Once the time event has ﬁ nished, the DMA1 brings the external audio source back to the level LLIN according to a programmed fade time TFIN.

PAGE 16 AMIS-DMA1 INSTALLATION & OPERATION MANUAL

PLAYLIST OPERATION

6.1 Introduction to playlist mode operation

When the ﬂ ash memory is inserted, the DMA1 analyses its content to deﬁ ne its mode of operation based upon the ﬁ les present:

1. File: PLAYLIST.TXT plays audio ﬁ les in sequence according to the list present in the ﬁ le

2. File: 1.M3U, 2.M3U, 3.M3U, 4.M3U, 5.M3U, 6.M3U, 7.M3U plays audio ﬁ les in sequence according to the list present, activated by logic input

IN1 = 1.m3u IN2 = 2.m3u IN3 = 3.m3u IN4 = 4.m3u IN5 = 5.m3u IN6 = 6.m3u IN7 = 7.m3u

During play the four command buttons REW, STOP, PLAY and FWD are active.

6.2 What is a playlist ﬁ le?

The DMA1 is able to follow a sequence or list of audio ﬁ les; this play list is a simple text ﬁ le called playlist.txt which can be inserted in the main directory of the same memory containing the audio ﬁ les.

Follow a few, easy rules to set the sequence:

Example 1 Example intro with 3 with part 1 numbers: 7 names: part 2 9 monologu 5 music 01 part 3 005 ﬁ nale

6.3 Playlist activation by logic inputs - MPLL (Mode PLayList) parameter

The seven available playlists activated by the logic inputs, can be played with different modes depending upon the varying needs.

To choose between the different modes of operation the conﬁ guration parameter MPLL (Mode PLayList) must be deﬁ ned in the conﬁ g.txt ﬁ le.

When the ﬂ ash memory card is inserted, the DMA1, depending on the setting of the parameter MPLL in the ﬁ le conﬁ g.txt, will switch over to the relevant mode of operation.

IMPORTANT!

• The names of the 7 playlists are ﬁ xed

• The loading times of the Playlists may last even tens of seconds, during which the DMA1 is not able to play

IMPORTANT!

• Rename the MP3 audio ﬁ les with numbers or names with 8 characters max.

• Do not write in the extension (.mp3)

• Max. 500 MP3 ﬁ les per playlist

Insert the ﬂ ash memory card and wait for the DMA1 to read the playlist. At the end of the reading operation, if the names of the pieces have been ﬁ tted in correctly, the DMA1 will automatically start to play the MP3 ﬁ les in the programmed sequence or wait the activation of a logic input.

SERIAL RS485 COMUNICATION

9.1 RS485 communication

The DMA1 can be connected to a Crestron control system or similar via RS485 serial connection.

Interference effects and induced noise on the serial line may cause anomalous behaviour and possible damage to the DMA1 unit. To avoid this, take the following precautions:

1. Do not let the serial cables transit the same conduits as power cables or cables with elevated voltage. Maintain a safe distance of at least 10 cm. between these cables

2. Connect the serial cable screen to the ground of one of the RS485 devices (do not connect the screen at both ends)

3. Disconnect power from the DMA1 and control system before wiring the serial control lines

The DMA1 supports up to 4 different RS485 modes of operation, according to the RS485 electrical standard. This serial multipoint communication supports the connection of up to 32 devices, with a maximum bus distance of 50 metres.

The DMA1 devices connected to the RS485 bus can not autonomously begin communication, but can respond to a speciﬁ c request (command) from a control system.

IMPORTANT!

• The internal electronics of DMA1 are not galvanically insulated from the RS485 line; in case of short circuit or discharge to ground, it is possible to damage not only the DMA1, but the control system to which it is connected!

• The control system must remember to ignore the transmission echo from the control system that is returned through the RS485 serial line.

IMPORTANT!

• To enable the serial port through the IN5/485A and IN6/485B pins, remove the cover of the device and move the P1 and P2 jumpers, as indicated in the following ﬁ gure.

• With an RS485 connection termination resistors must be applied on both extremes of the serial line to avoid the generation of stationary waves and to deﬁ ne the impedance of the serial line - even in absence of serial communications. The DMA1 features internal termination resistors, enabled through a JP1 bridge jumper. To deactivate the terminating resistors, remove the cover of the device and remove the JP1 jumper indicated in the following ﬁ gure.

The RS485 connection parameters (speed, parity, check-sum, etc.) are set in the conﬁ guration ﬁ le conﬁ g.txt. (par. 9.2).

9.2 Serial port communication parameters (conﬁ g.txt)

The parameters of the RS485 serial port (length of the packets, parity, speed, etc.) are set in the conﬁ guration ﬁ le conﬁ g.txt.

These parameters must be compatible with the external control system to which DMA1 is connected.

IMPORTANT!

To make changes to the communication parameters active, it is necessary to power-cycle the DMA1 after having inserting a ﬂ ash memory card with the updated conﬁ g.txt ﬁ le.

The following table lists the values and parameters needed to connect the DMA1 to a control system (protocol, speed, timings, etc.).

IMPORTANT! notes for the control system

The DMA1 is ready for serial communication instructions under the following conditions:

• When DMA1 is turned on

• When the previous communication instruction has been completed

• When the timeout time for the last received/transmitted packet has expired

PAGE 30 AMIS-DMA1 INSTALLATION & OPERATION MANUAL

SERIAL RS485 COMUNICATION

Reply wait time (CMDR)

This is the delay time before the transmission of a reply message, required by some control systems to switch between the state of transmission and the state of reception. The reply waiting time determines the minimum delay before the DMA1 sends data in reply to the message received from the control system. Set this time at a value different from 0 only if the control system requires it, since the delay determines an extension of the time needed to complete the command.

9.3 “ Framing” error

A framing error may take place if nothing is being transmitted on the serial line. In order to avoid this mishap, it is recommended that the control system ignores all data until it has received one of the STX, ACK or NAK characters coming from a DMA1.

9.4 NAK reply by a DMA1

The reply with the NAK character is sent from DMA1 to the control system when any kind of error is detected in the received message.

9.5 Transmitting a command from a control system

When sending a command from the control system to a DMA1, make sure it is sent after a minimum delay of 10ms after receiving the last instruction from the DMA1 to ensure the DMA1 has had sufﬁ cient time to process the last request.

9.6 Basic format of dedicated protocols

The DMA1 supports up to four dedicated RS485 protocols. Which of these four protocols is used by the serial connection is deﬁ ned in the conﬁ guration ﬁ le conﬁ g.txt (par. 9.2). The difference between these four formats is due to the presence or absence of CheckSum and/or of the end-0f-packet characters CR (Carriage Return, character 0DH) and LF (Line Feed, character 0AH).

9.7 Basic set-up of data packets

Control code

DMA1 address

Command code

Command data

CheckSum

CR/LF control codes

IMPORTANT!

When using an RS485 bus remember to ignore the echo of the command that is sent from the control system (with RS485 an echo is always present).

PAGE 31AMIS-DMA1 INSTALLATION & OPERATION MANUAL

SERIAL RS485 COMUNICATION

IMPORTANT!

The introduction of CheckSum at the end of the block of data and characters of CR + LF is deﬁ ned in the conﬁ guration ﬁ le conﬁ g.txt (par. 9.2).

9.8 Control codes

The control codes are characters (they belong to the ﬁ rst 32 ASCII characters and cannot be printed out) which deﬁ ne the type of information contained in the packet following them. The control codes used are those which appear on the following table. The DMA1 initialises serial communications when it receives the character ENQ.

MNEMONIC CODE DESCRIPTION

STX

ETX 03H End TeXt. End of reply packet

ENQ 05H EnQuiry. Beginning of packet addressed to DMA1

ACK 06H ACKnowledged. Beginning of reply packet: all OK!

LF 0AH Line Feed. End of line code

CR 0DH Carriage Return

NAK 15H Not AcKnowledged. Beginning of reply packet: ERROR!

9.9 Address (ADD)

The address is a unique number that allows the control system to establish communication with one of the various modules connected to the same serial communications line. The DMA1 address is deﬁ ned in the conﬁ guration ﬁ le conﬁ g.txt (par. 9.2).

02H Start TeXt. Beginning of reply packet

9.10 Command (CMD)

CMD (command) is used to deﬁ ne an operation to be carried out (for example PLAY, reading the state or setting of the volume). Commands are deﬁ ned as ASCII characters and consist of 2 characters. In the following sections of this chapter a list of commands (and detail about each command) will be provided.

IMPORTANT!

When setting the address it is necessary to be careful to not deﬁ ne more than one DMA1 with the same address, otherwise the communication becomes confused and irregular. The address can assume any value between 00H and 1FH. The address is expressed in ASCII characters and consists of 2 characters.

PAGE 32 AMIS-DMA1 INSTALLATION & OPERATION MANUAL

SERIAL RS485 COMUNICATION

9.11 CheckSum (CHK)

CheckSum ensures that packets are complete and not corrupted during transmission by any noise or interference induced on the RS485 bus.

The CheckSum is calculated summing the hexadecimal values of the ASCII characters contained in the data packet (excluding the control code). The two least signiﬁ cant characters (in hexadecimal) of the result represent the CheckSum value, and are added to the end of the packet (before any CR and LF characters).

NOTE: CheckSum is enabled by the CMCK parameter of the

conﬁ guration ﬁ le conﬁ g.txt.

The following ﬁ gure shows an example of the calculation of a CheckSum in a command packet delivered by the control system

ADD CMD DATA CHK

0 1 5 0 0 1 3 2 8 C

• If CMCK=1, CheckSum will be calculated automatically and added to the reply packet (any packet beginning ’STX’). When a packet is received, the DMA1 calculates the CheckSum of the received packet locally and compares it with the one contained in the packet itself. If the calculated CheckSum is identical to the received CheckSum the DMA1 perform the command, otherwise an error packet is transmitted (packet beginning with ‘NAK’).

• If CMCK=0, CheckSum will not be appended to transmitted packets and will not be compared (also because it is missing in the data) in the received packets.
