Connection and General information
DMS3000 V2.20
MP3 Digital Audio Playback Card.
General
The DMS3000 is designed around industry standard MP3
compression technology. Audio data is stored on standard
multimedia cards (MMC). The DMS3000 series sound
stores can be recorded by the user with a suitable PC
equipped with an MMC card reader and sound card.
Message playback can be initiated in a number of ways
from a simple contact closure, RS485 or via text command
files assigned to a particular trip input giving an incredible
degree of control over the sound store.

I/O Connections
Power, Audio and Control pins of the DMS3000 Playback Card all appear
on the 64way DIN41612 edge connector (CON1) on the rear edge of the
PCB. ( If fitted )
Trip Inputs - Pins A10-13 B10-13
Trip inputs can initiate playback of a stored message directly or start a
command file which in turn can call any available messages. The eight
trip inputs can be configured as ACTIVE HI or LOW via JP6 shown in FIG
1 (default active LOW). Trip inputs can be individually configured as N/O
or N/C inputs (default N/O) in the CTL.txt file stored on the MMC card.
( detailed later )
Trip inputs can be configured as decimal or binary in the CTL.txt file
In decimal mode (default) 8 messages can be directly accessed.
In binary mode 255 messages are available.
Stop Input - Pin A14
A LOW pulse on this line will stop and reset playback of any running mes-
sage or command file. If the stop input is held low it will prevent playback
of any recorded message. ( Stop input line 5v active low standard TTL
levels )
Start Input -PinB14
When using binary trip inputs (255 messages) a LOW pulse on this line
will clock in the binary code presented on the 8 trip input lines and initiate
playback of the corresponding message.
When using decimal trip inputs (8 messages) this line is inactive.
RS485 Pins B15,A15
For future use. Do not connect.
FRAME Clock IN Pin A16
42Hz clock from master sound store is input to this pin when using
sound stores in Master / Slave configuration.
FRAME Clock OUT Pin B16
Output 42Hz clock to Slave sound stores when used in Master/Slave
configuration.
Run IN Pin B17
Receives control signals from master sound store at start and end of
sound files for synchronisation when used in Master / Slave configuration
Run OUT Pin B18
The RUN Output will provide a negative going signal for the duration of
any sound track that is playing. This signal is also used when using a
Master / Slave configuration
Sync IN Pin A17
Sync control signals when used in Master/Slave configuration.
Sync OUT Pin A18
Sync control signals when used in Master/Slave configuration.
Control OUT Pin B19

DIN41612 connection details.
Creating MP3 files.
STEP 1
The usual way to create a .mp3 file is to record the soundtrack into the
computer as a wav file using software such as “Adobe Audition”
STEP 2
Next edit the wav file so that any unnecessary silence is removed from
the start and end of the soundtrack. All editing must be carried out while
the file is still in a .wav format as it is not practical to edit an .mp3 file.
STEP 3
The third step is to encode the wav file to an mp3 file using “Audition” or
similar encoder. It is this point that determines the quality of the finished
mp3 file by selecting the most appropriate bit rate for the file. The lower
the bit rate, the lower the quality and bandwidth of the output file but a
lower bit rate would use less memory per second.
The usual bit rate for encoding mp3 files is 128Kbits per second which
will provide a bandwidth of 20Hz to 15KHz.
Example running times using a 32 Mbyte memory card.
Sample Rate Bit rate. Bandwidth. Running time.
44.1KHz 112Kbps = 20Hz to 13KHz = 38 Minutes
44.1KHz 128Kbps = 20Hz to 15KHz = 33 Minutes
44.1KHz 160Kbps = 20Hz to 18KHz = 26 Minutes
44.1KHz 192Kbps = 20Hz to 20KHz = 22 Minutes
Memory Card (MMC)
The DMS3000 currently supports MMC cards from 64MB to 1GB . We
can supply fully compatible cards which we recommend as some makes
of card are not compatible. Cards must be formatted with FAT16 only.
The MMC card used with the DMS3000 sound store must contain certain
files and directories to operate. These files are detailed below.
ROOT files and Directories.
Files named CFG.txt (configuration data) and CTL?name.txt (control
data) must be present in the ROOT DIRECTORY. A subdirectory named
DATA must also be present to hold your .mp3 sound files and any com-
mand.txt file associated with any particular trip input.
CFG.txt contains Configuration data for the DMS3000 chip set. This file
is set as READ ONLY and MUST NOT BE MODIFIED.
CTL?name.txt contains user settable parameters for the sound store
such as trip input conditioning, tone control presets, RS485 addressing
etc. the full list of available control commands are described later.
DATA SUB DIRECTORY
This Directory must contain all .mp3 sound files and any command files
you require.
.mp3 Sound files. Must be named in the following manner to enable
the sound store to identify message files.
The first 3 digits in the file name assign the message to it’s trip input
number, messages 001 to 255 are available.
The next string of characters are used for your message name if re-
quired, the first 16 of these characters will be displayed on the 2x16 LCD
display if fitted.
File Extension the last 4 characters MUST ALWAYS BE .mp3 for a
valid file name.
Example 1, 001TEST MESSAGE.mp3
Example 2, 156This is a test.mp3
Both the above are valid file names for messages 1 and 156.
Command files
If required a command text file can be written and assigned to any trip
input to provide access and control over any or all .mp3 sound files pre-
sent in the DATA directory. Command files enable you to use features
such as message selection / playback, delay timers, message sequenc-
ers, trip conditioning, random message selection etc (see command file
section). An example command file name assigned to trip input 1 would
be 001?name.txt When tripped command files take priority over
any .mp3 sound file with the same message number.
eg. 001?name.txt would have priority over 001?name.mp3 however
message 001?name.mp3 could still be played from within the command
file.

) End of file marker
Control file syntax information.
All commands must start with “/”
All commands must end with “;”
The last command must be followed by “) “ on the next line.
There must be an “=” sign after the command and before the data.
There must not be any spaces within the command string.
All commands are lower case.
You may type remarks after the semicolon “;” but the remarks must not
contain any control characters such as /or )or ;or =.
Detailed explanation of each control command.
osbe One shot bit enable
This command allows each of the eight individual trip inputs to be set up
with one shot functions. This means that if a trip is one shot enabled,
and that trip line is held active beyond the end of a file, the selected file
will not run again. The trip line must be released before it can operate
again. If the trip line is not one shot enabled, the selected file will loop if
the trip is held on at the end of the file.
To select one shot mode, enter a “1” corresponding to the trip number
otherwise enter a “0”.
Trips 8………..1
/osbe=00000000;
For example, if trips 1,3,7,8 are one shot enabled the command would
be: /osbe=11000101;
ncbe Normally closed bit enable
This command allows each of the eight individual trip inputs to be set up
to operate with normally closed contacts such as a PIR.
To enable a normally closed contact trip, enter a “1” corresponding to the
trip number otherwise enter a “0”.
Normally closed bit enable
0=Normally Open, 1=Normally Closed
Trips 8………..1
/ncbe=00000000;
For example, if trip 1 & 2 are to be on normally closed
contacts the command would be: /ncbe=00000011;
cont Continue after interrupt
This command will allow an interrupted cmd.txt or mp3 file to resume
from the point it was stopped after the interrupting file has finished. For
example, a long background music file could be playing and then a voice
instruction needs to be played. After the voice mp3 file has finished, the
background track would fade back in at the point it was interrupted. This
command will only work if either “mint” or “pint” is set.
Note. It is possible for a third file to interrupt the second file, in this case,
the first file will always be the one that resumes. However if the third or
subsequent file number is the same as the first file, the first file will fade
back in and continue.
/cont=0; The interrupted file will not continue after interruption.
/cont=1; The interrupted file will continue.

biny Binary coded trips
Setting this command to “1” will allow access to 255 .mp3 sound files or
command files by applying the appropriate binary code number on to the
trip inputs and then applying the active low start signal.
/biny=0; up to eight files can be accessed with the 8 trip lines
/biny=1; up to 255 files can be accessed using binary codes
Binary equivalent value for each trip input.
Trip 1 = 1, Trip 2 = 2, Trip 3 = 4, Trip 4 = 8,
Trip 5 = 16, Trip 6 = 32, Trip 7 = 64, Trip 8 = 128.
Example.
To access file “043?name.mp3” you must activate trips 6,4,2,1 then apply
an active LOW to the start Pin. This equates to 32+8+2+1=43
pint Priority interrupt enable
This command if “1” will allow any other valid trip of a lower value to
cancel a currently playing file and run the new file. The file can be a .mp3
sound or a command file.
If the command = “0” any new trip will be ignored until a currently playing
file has finished.
/pint=0; No priority interrupt allowed
/pint=1; Priority interrupts allowed
NOTE: Mint must be set to “0”
mint Interrupt enable
This command if “1” will allow any other valid trip to cancel a currently
playing file and run the new file.
If the command = “0” any new trip will be ignored until a currently playing
file has finished.
/mint=0; No interrupt allowed
/mint=1; Interrupts allowed
pvol Preset volume
This command allows the output to be preset thus preventing operators
from adjusting the front panel volume control. If this command is not used
or set to zero, the front control will operate.
Formula for arriving at value for data byte.
value = 255 - (4 x ?dB)
Examples:
0dB Max Vol /pvol=255;
-6dB /pvol=231;
-40db /pvol=95;
-63dB Min Vol /pvol=1;
Front control active /pvol=0;
ptre Preset Treble
This command allows the treble boost or cut to be preset thus preventing
operators from adjusting the front panel treble control. If this command is
not used or set to zero, the front control will operate.
Note. When the treble control is increased, you will notice that the overall
volume will decrease by an equal amount. This is to allow maximum drive
at the outputs without sacrificing quality. You may override this function
with the “tnat=?;” command but the overall level will be reduced to allow
headroom for the treble boost.
Treble Examples:
10.5 dB boost /ptre=240; 1.5dB cut /ptre=112;
9.0 dB boost /ptre=224; 3.0dB cut /ptre=96;
7.5 dB boost /ptre=208; 4.5dB cut /ptre=80;
6.0 dB boost /ptre=192; 6.0dB cut /ptre=64;
4.5 dB boost /ptre=176; 7.5dB cut /ptre=48;
3.0 dB boost /ptre=160; 9.0dB cut /ptre=32;
1.5 dB boost /ptre=144; 10.5dB cut /ptre=16;
Flat /ptre=128; Front control active /ptre=0;
pbas Preset Bass
This command allows the bass boost or cut to be preset thus preventing
operators from adjusting the front panel bass control. If this command is
not used or set to zero, the front control will operate.
Note. When the bass control is increased, you will notice that the overall
volume will decrease by an equal amount. This is to allow maximum
drive at the outputs without sacrificing quality. You may override this
function with the “tnat=?;” command but the overall level will be reduced
to allow headroom for the bass boost.
Bass Examples:
10.5 dB boost /pbas=240; 1.5dB cut /pbas=112;
9.0 dB boost /pbas=224; 3.0dB cut /pbas=96;
7.5 dB boost /pbas=208; 4.5dB cut /pbas=80;
6.0 dB boost /pbas=192; 6.0dB cut /pbas=64;
4.5 dB boost /pbas=176; 7.5dB cut /pbas=48;
3.0 dB boost /pbas=160; 9.0dB cut /pbas=32;
1.5 dB boost /pbas=144; 10.5dB cut /pbas=16;
Flat /pbas=128; Front control active /pbas=0;
pbal Preset balance
This command will preset the left and right balance of the outputs. When
“mono” is selected in the control file, or a mono signal is stored, the
balance control will still affect the output levels and not the mix from the
D/A converter.
If this command is not used or set to zero, the front control will operate.
Examples:
Front control active /pbal=0;
Full left /pbal=1;
Equal /pbal=128;
Full right /pbal=255;
mono Mix outputs to mono
This command will mix both left and right channels together to provide a
mono output. The balance control will still alter the output balance.
/mono=0; Stereo
/mono=1; Mono
tstb Test pushbutton code
The front mounted push button has a default select number of “1” but it
can be assigned with any number from 1 to 255. This button will then
access an mp3 file or command file with the same number.
If the value “0” is assigned or the command is not used, the button will
default to code “1”.
eg. /tstb=1;
tnat Tone attenuator over-ride
This command if set will prevent the gain being altered when the bass or
treble is increased but the overall output will be reduced by ?dB to allow
headroom for the tone boost.
Attenuation = ? x 1.5dB
/tnat=0;Tone attenuator operates with onboard tone controls.
/tnat=1;Tone attenuator set to -1.5dB
/tnat=7;Tone attenuator set to -10.5dB (maximum)
WARNING. If insufficient attenuation is provided, it is possible for
severe audible clipping to occur when the treble or bass is in-
creased. The amount of attenuation is dependant on the audio
content of the mp3 files.
ncmd Disable command files
This command will prevent the DMS3000 from searching for command
files. This will speed up the access time if there are several hundred mp3
files on the memory card and you do not require the use of command
files.
/ncmd=0; Command files available
/ncmd=1; Command files disabled

self Self interrupt of MP3 files
This command will allow an MP3 file to be interrupted by itself if the trip is
removed and then re-applied.
Note: The MP3 can still interrupt itself even if “mint” and “pint” are set to
“0”. This command is useful to achieve a “scratching” effect by re-tripping
repeatedly,
/self=0; Currently playing MP3 cannot be interrupted by the
same trip number.
/self=1; Currently playing MP3 will be interrupted by the same
trip number if released and re-applied.
fast Fast access of mp3 files
Using this command allows very fast interrupting or restarting of MP3
files. Files must be encoded at 48KHz sample rate and bit rate must be
192KBps stereo when using this mode.
Note. One shot mode does not work with this command and also the trip
inputs are not debounced as thoroughly to improve access time therefore
external trip wiring should be kept short and screened if possible.
/fast=0; Normal operation
/fast=1; Fast mode enabled
nbuf No buffer flush
This command is normally used in conjunction with “fast” to speed up
interrupting time by preventing the sound store from flushing its decoder
data buffer. Files must be encoded at 48KHz sample rate and bit rate
must be 192KBps stereo when using this mode.
/nbuf=0; Decoder buffer is flushed when an MP3 is
interrupted.
/nbuf=1; Decoder buffer is not flushed when an MP3 is inter
rupted.
fixl Fix left output to max level
This command can be used to prevent a control tone track or smpte track
from being turned down with the volume control. This command will set
the left output to maximum. The volume control will not affect the left
channel although the Bass and Treble will still have an effect and the
tone attenuator will also affect the output unless the tone attenuator is
preset using the “tnat” command above.
/fixl=1; Left output fixed
/fixl=0; Left output Variable
fixr Fix right output to max level
This command can be used to prevent a control tone track or smpte track
from being turned down with the volume control. This command will set
the right output to maximum. The volume control will not affect the right
channel although the Bass and Treble will still have an effect and the
tone attenuator will also affect the output unless the tone attenuator is
preset using the “tnat” command above.
/fixr=1; Right output fixed
/fixr=0; Right output Variable
scn1 Scan trips once
This command allows the eight trip inputs to be scanned and played one
after the other in ascending order.
Example: If trips 1,3,7,8 were all activated together, the sound store
would play message 1 then 3 then 7 then 8 and then stop. To restart the
sequence, either remove all trips and reapply or ground the stop input
momentarily.
NOTE: Function only works in decimal trip mode
Do not use mint or pint commands
Test button will set sequencer to trip number assigned to it
This function will sequence sound or command files
/scn1=1; Multi trip scanning enabled
/scn1=0; Not enabled
scnc Scan trips continuously
This command allows the eight trip inputs to be scanned and played con-
tinuously one after the other in ascending order.
Example: If trips 1,3,7,8 were all activated together, the sound store
would play message 1 then 3 then 7 then 8 and then start again. To
restart the sequence, either remove all trips and reapply or ground the
stop input momentarily.
NOTE: Function only works in decimal trip mode
Do not use mint or pint commands
Test button will set sequencer to trip number assigned to it.
This function will sequence sound or command files
/scnc=1; Continuous multi trip scanning enabled
/scnc=0; Not enabled
bank Banked trip inputs.
With banked trip inputs, it is possible to select up to 128 files divided into
16 banks of 8 files.
Banked trip inputs use ‘sync in’ (pin A17) to select banks 1-8 and ‘run
in’ (pin B17) to select banks 9-16.
To operate, ground ‘sync in’ or ‘run in’ momentarily then activate a trip
input to select a message bank (1 of 16). The next trip input entered
selects the file within the bank. The bank remains valid until another
bank is selected.
Note:
This only works with decimal trips ie /biny=0;
Bank selecting trip must be released before selecting the file to be
played.
Busy led lights with run/sync in and goes out when bank is selected.
/bank=1; Banked trips active
/bank=0; Banked trips inactive
wdog Multimedia Card Watchdog
In standby mode, the MMC card is checked every 5 seconds to ensure it
is still inserted and functioning normally. The busy led will blink very

pian Piano style trip inputs.
This command will allow the eight trip inputs to function like a piano key-
board. When a trip is released, the mp3 that is playing will stop after a
short delay set by the orun command.
/pian=1; Piano mode active.
/pian=0; Normal operation
orun MP3 overrun after trip release (pian )
In Piano mode, this command sets the delay time before the mp3 will
stop playing after the trip is released. The value can be 0 to 20 in 50ms
increments.
eg. /orun=2; = 100ms overrun

autp Automatically plays a file on power up
Plays an MP3 or runs a command file on power up and when no trips
Are active. Can be stopped by stop input but will restart when stop pin
is released. This mode can be cancelled within a command file by
using “/autp=0;”
/autp=0; MODE Inactive
/autp=?; ? = 1-255 number of MP3 or command file to
play on power up and when no other trip is active.
scrl Scroll through MP3 files.
Preselect MP3 using ‘sync in’ pin to scroll up and ‘run in’ pin to scroll
down. Activate ‘start’ to play and ‘stop’ to cancel a MP3. You must use a
command file on power up to set the start and end limits for the scroll
group. Any missing mp3’s from the group will be skipped during scroll-
ing. This function only works with MP3 files & not command files.
/scrl=1; Enable scroll mode.
/scrl=0; Disable scroll mode.
How to setup ‘scrl’
This example assumes twenty four messages on the card to play.
In the ctl.txt file, set ‘/autp=254;’ Which will run a command file numbered
254 on power up.
Contents of command file ‘254limits.txt’ in data folder.
/lims=1; Assumes first mp3 in group is 001namename.mp3
/lime=24; Assumes last mp3 in group is 024namename.mp3
/autp=0; Disables this file from running again.

Command files
If required a command text file can be written and assigned to any trip
input to provide access and control over any or all .mp3 sound files pre-
sent in the DATA directory. Command files enable you to use features
such as message selection / playback, delay timers, message sequenc-
ers, trip conditioning, random message selection etc. An example com-
mand file name assigned to trip input 1 would be 001name.txt.When
tripped, command files take priority over any .mp3 sound file with the
same message number.
eg. 001name.txt would have priority over 001name.mp3 however mes-
sage 001name.mp3 could still be played from within the command file.
Command file naming xxxname.txt
NOTE: You cannot use command files if running multiple DMS3000’s in
sync with each other.
The first 3 digits of the file name relate to the trip input required to exe-
cute the file 001 to 255. Next (if required) a specific name can be used
for your identification purposes. The last 4 digits must always be .txt
Example:
A valid command file name for trip input 1 would be “001 test command
file.txt “as could “001.txt “
The following commands can be used in a command.txt file placed in
the DATA subdirectory of a MMC card.

Explanation of commands.
play Play selected .mp3 file
Select and play the mp3 file indicated. Allowable range is 1 to 255. If the
mp3 file does not exist, the next command will run.
/play=2; plays sound file 002?name.mp3
NOTE:
If an mp3 is started and then the same mp3 is selected again whilst still
running, the playing mp3 will not be interrupted however loop mode
‘loop’ will be cancelled if active. Any mp3 file called from within a com-
mand file will be cancelled if the command file ends before the MP3. A
wait command such as ‘wtan’ or ‘wtor’ must be used to make the com-
mand file wait for the end of the mp3 file.
stop Stop playing any .mp3 file
Will stop a currently playing message. Data byte should be 1.
/stop=1; Stop any playing mp3
/stop=2; Cancel a ‘cont’ held cmd file
/stop=3; Cancel a ‘hold’ held cmd file
volm Volume control
This command allows you to change the preset volume level within a
command file.
Formula for arriving at value for data byte.
value = 255 - (4 x ?dB)

/volm=255; 0dB
/volm=231; -6dB
/volm=95; -40dB
/volm=1; -63dB
/volm=0; Front panel control operational.
dltm Delay timer value
This command provides a delay timer. Delays can be from 1 to 99 min-
utes or seconds depending on the range selected by the ‘dlrg’
command (see below).
Every time this command is run, the delay timer will be set to the value
declared by the data bytes (1 to 99).
/dltm=45; Delay timer set to 45
dlrg Delay timer range and control
x = timer displayed 0=display off 1=display on
y = single shot timer 0=single shot 1=continuous

timv User variable or fixed timer
This timer can either use the front panel “aux” control or can be preset
with a value within the command file. Delays can be from 1 to 99 minutes
or seconds depending on the range selected by the “timr“
command (see below). Every time this command is used, the variable
timer will be set to the value declared by the data bytes. If the data byte
is zero, the value set by the aux control will be used to set the timer
0 to 64. Turning the aux control whilst the timer is running will reset the
timer to the new value set by the control. If the control is set to zero, the
timer will pause and will not run again until the control is set to anything
other than zero.
Note, If you intend using the aux control to set a variable timer, you must
use the “ /pbal=128; ”preset balance command in the control file to fix
the balance to central.
timr Variable timer range and control
x = timer displayed 0=display off 1=display on
y = single shot timer 0=single shot 1=continuous
z = timer range 0=seconds 1=minutes
Command format : /timr=xyz; Valid values for x,y,z can be 0or 1
Examples.
A continuous running variable minute timer with count displayed.
/timr=111; where x=1 / y=1 / z=1
/timv=0; time set via “aux” control variable 0 to 64
A single shot fixed timer of 20 seconds with LCD display.
/timr=000; where x=0 / y=0 / z=0
/timv=20; timer set at value of 20
A single shot variable second timer without LCD display.
/timr=100; where x=1 / y=0 / z=0
/timv=0; time set via “aux” control variable 0 to 64
mint Interrupt enable
If the command = 1this will allow any other valid trip to cancel a currently
playing file and run the new file. The interrupting file can be an .MP3
sound file or a command .txt file.
If the command = “0” any new trip will be ignored until a currently playing
file has finished.
/mint=0; No interrupt allowed
/mint=1; Interrupts allowed
Note.
This command over-rides the “/mint;”command used within the Control
file.
pint Priority interrupt enable
If the command = 1 this will allow any other valid trip of a lower value to
cancel a currently playing file and run the new file. The interrupting file
can be an .mp3 sound file or a command .txt file.
If the command = 0any new trip will be ignored until a currently playing
file has finished. eg.
/pint=0; No priority interrupt allowed
/pint=1; Priority interrupts allowed
Note: This command over-rides the “/pint ” command used within the
Control file.
outp Output control transistors
The transistor output Control-Out (pin B19) is available for external use
as are Sync-Out (pin A18) and Run-Out (pin B18)if their normal func-
tions are not required.
Note: You must use “actl” in your ‘control.txt’ file to disable the normal
functions of the sync-out and run-out transistors.
x = Sync-Out Pin A18 0=output OFF 1=output Active
y = Run-Out Pin B18 0=output OFF 1=output Active
z = Control-Out B19 0=output OFF 1=output Active
Command format : /outp=xyz; Valid values for x,y,z can be 0or 1
Output will remain in its last state unless the stop line is activated in
which case it will be de-activated. The rating of outputs is 150mA max
@ 30 volts max.
DO NOT FORGET TO FIT A DIODE ACROSS ANY INDUCTIVE LOAD
ON THE OUTPUT TRANSISTORS.
lims First message of group
Set the lowest message number of a group of messages to be included
for sequence, random or scroll .mp3 file playback.
/lims=10; First message in group set to 010?name.mp3
lime Last message of group
Set the highest message number of a group of messages to be included
for sequence, random or scroll mp3 file playback.
/lime=20; Last message in group set to 020?name.mp3
Note. When applying the above group limit commands they will not reset
the random number generator or the sequencer unless the generators
are outside the limits being applied, in which case the number genera-
tors will be set to the start limit value.
rndm Play a random mp3
A random mp3 file from the group defined above will be selected and
played. Data byte should be 1.
/rndm=1; Play a random message within group set by lims
and lime.
sequ Play mp3 file in sequence
This command controls the mp3 sequencer. The sequencer allows you
to play a number of mp3 files in numeric ascending order.
/sequ=0; Play next message in sequence
If the data byte set to 0, the next mp3 file from the group defined by the
“lims” and “lime” commands will be selected and played. After the last
file in the group has been played, the sequence will restart from the first
number in the defined group.
/sequ=1; Reset sequencer only
If the data byte is set to 1, the sequencer will be reset to the first mes-
sage set by “lims”. No message will play at this time.
/sequ=2; Reset sequencer and play first mp3 in group
If the data byte is set to 2, the sequencer will be reset to the first mes-
sage set by “lims” and the first mp3 in the group will play.
goto Goto line number
This command will cause the command reader to return to a previous
line number in the command file to allow a repeat of previous commands
to be run until the loop counter reaches zero. When the counter reaches
zero, the command after ‘goto’ will run. The loop command should be
set before this command is used. Do not count blank lines within the
command files.
/goto=4; Return to line 4
loop Loop counter
This command sets the number of loops that the “goto” command will
make.
eg.
/loop=0; Goto command will be ignored
/loop=1; Goto command will loop once
/loop=254; Goto command will loop 254 times
/loop=255; Goto command will loop ad infinitum
Note: maximum loops with exit to other code = 254 times
plal Loop current MP3
This command will cause the currently playing mp3 file to run continu-
ously.
It will be cancelled by any other play type command such as “play=x”
“sequ=x” “rndm=x” “plal=0” or “stop=1”
The command file ending will also cancel this mode.

cond Conditional branch
This command allows you to branch to one set of commands if the condi-
tions are true or a different set of commands if false. When using this
command, you must use the true=1 and endc=1 commands also.
If the conditions are not met then the commands following cond and upto
the next true command will be run followed by the commands after endc
If the conditions are met then the commands following true and upto the
command named endc will be run. This command is not nestable.
/cond=wxyz; Values for w,x,y,z can be 0or 1
w= Check for trip input 1= Check for trip input
equal to value set by
trip in command file.

gseq Multiple group message sequencing.
Multiple message sequencing allows upto 8 separate seuquencers to
run with upto 10 messages in each.
gseq=2 plays messages 21-29 from trip 2
gseq=5 plays messages 51-59 from trip 5
Set sequencer start and end limits to the number of messages in each
group being played at the start of each command file using the ‘gseq’
command. See below for syntax.
Note. The sequencers follow a common counter so if you play the first
message in sequencer group 1, the next trip received will play the 2nd
message in what ever group was selected with the trip.

cmnd Switch to new command file
Cancels and saves any playing mp3 and also saves current position of
command file. Searches for new command file and if found will run the
new command file. It is possible to manually hold the mp3 and release it
in the new command file using the ‘hold’ command. Or hold it in the first
command file and release the mp3 after returning back to the original
command file.
If the new cmd file is non-existent, the next command line in the calling
file will run.
This command also allows longer command files than 64 lines by daisy
chaining them and also allows interaction etc.
If /cont=1 is set in the ‘ctl’ file the first cmd file will continue from where it
Left from after the interrupting file has ended.

NOTE. PLEASE ADVISE GOLDING AUDIO LTD IF YOU INTEND TO
SYNCHRONISE DMS3000’S TOGETHER AS WE MUST PERFORM A
MINOR MODIFICATION TO THE PCB TO ALLOW SYNCHRONISA-
TION.
The following conditions must be met when synchronising
DMS3000 sound stores.
NOTE: You cannot use command files if running the DMS3000 in sync
with each other.
1: MP3 files must be 48KHz sample rate and 192 Kbps.
2: Files must be exactly the same size.
(right click and check properties for exact file size)
3: The slave MMC cards must be the same capacity as the master
MMC card and be the same format (fat12/16).
4: All DMS3000’s must be powered up and down together.
5: Boards used must be modified DMS3000 iss4 boards or later.
6: Trip must be at least 250mS duration.
7: All inter board connections must be short and screened if
possible.
8: The sysclk must be a twisted pair between units.
9: The last slave on the run must have the termination link fitted to
the SYSCLK RS485 receiver. JP4 right pins.
It is strongly recommended that multi-track systems are built within rack
mount card frames to ensure short cable lengths and synchronized power
up.
Certain functions within the ‘control.txt’ file on both master and slave
cards must also be set as active or inactive as outlined below:
Master card control.txt file.
These items must be active in the “control.txt” file.
/ncmd=1; disable command file search
/mast=1; enable master
These commands must be inactive.

Signals between DMS3000 units.
SYSCLK (RS485) 10Mhz pins A19 and A20
This is the decoder system clock from the master supplied to the slaves
to prevent drift between boards. Essential for looped systems. Not es-
sential for short tripped syncs
FRMCLK
This is a 41.6Hz clock from the master to the slaves to ensure that the
mp3 files are all started at exactly the same time.
SYNC
Master card
This line outputs sync pulses at intervals to maintain synchronisation
between sound stores.
Slave card
This line receives sync pulses from the master sound card at intervals to
maintain synchronisation between sound stores.
RUN
Master Run out
This line goes low 1 frame before audio is output to tell the slaves to
output audio on the next frame edge.
Slave Run in
This input receives a pulse indicating when to output audio.
TRIPS
Connect master and slave trips together and ensure the trip parameters
match in the control file.

Bus board connections
The diagram below illustrates how Master and Slave
sound stores are connected together in synchronised
multi-track applications.
NEST UNIT SYSTEM
When multiple sound stores are required, boards can be
housed in a 3U nest unit. All required connections are
presented to a bus board as detailed below.
