Overview
Thank you for purchasing the Compact FLASH IV Digital Audio System; be assured that it will
provide you with thousands of hours of trouble free, solid-state operation. You will also find that it is simple
to change audio themes or tracks and is easy to make your own recordings or “program” the device.
End users can change the audio themes or tracks simply by inserting another, different Secure Digital SD
Card, as easily as the changing of a cassette tape. Multiple cards can be programmed with different audio
themes or tracks allowing daily, hourly, weekly or monthly changes. It truly is as simple as removing the old
card and plugging in the new one. Depending on the manufacturer, SD Flash Cards may be re-used up to
100,000 times.
Sound files are easily copied onto the card via your PC or laptop, using a SD Flash to USB adapter. As
the files are copied to the SD Flash Card, they are renamed. This process instructs the Compact FLASH IV
Digital Audio System to associate sounds with contacts and control how and when they are played.
See the Quick Start section below to try out your CFSound-IV immediately.

Main Connector
Most of the connections to the CFSound-IV are supplied to the unit with a ten pin, 2-piece pluggable
terminal block style connector at Main.
Power Supply Connection
The CFSound-IV requires a regulated or unregulated voltage of 10V to 18V DC.
Voltages above 18VDC will damage the unit.
The unit has resettable fusing internally to protect the Power input. Should the fuse trip, remove power,
correct the fault, wait a minute for the thermal fuse to cool and reset, then, re-apply power. The non-OEM
version of the CFSound-IV is supplied with a 120-240VAC 50/60Hz wall mounted transformer rated at
15VDC @ 1.6A.
ACS supplies different versions of the wall-mounted transformer power supply for the CFSound-IV. The
designated positive lead which should be connected to pin 9 of the Main connector with the other negative or
ground lead connected to pin 10.
Built-in Contacts Connection
The Push-To-Talk (PTT) relay dry contact output on the Main connector may be activated whenever a
sound is playing. The contact output is implemented with a relay whose contacts are rated at 1A @ 30VDC
maximum. The Common and Normally Open relay contacts are available on the Main connector.
The contact inputs on the Main connector appear logically to the CFSound-IV as Contact #25 & #26,
and may be activated by momentarily applying ground to the Input Contact #xx pin on the Main connector.
The contact inputs are implemented with an optocoupler. The Cathodes of the LEDs in the optocoupler are
connected to the Contact #25 and #26 Input pins. The Anodes of the LEDs in the optocoupler are connected

to an internal 12VDC power supply, with a 680 ohm current limiting resistor in series. The output transistor
of the optocouplers have 10K pull-up resistors on their collectors, with the emitters connected to ground and
are buffered by an inverting gate. The following diagram is representative of the Contact #25 input and is
similar for Contact #26:
Contact #25
GROUND
+12v
+5v
680
ohm

ohm
The input is activated by sinking current from the Contact input pin to ground. A Ground connection is
supplied on pin 10 of the Main connector for this purpose. The input current sink requirement is
approximately 10mA. The contacts are associated with sound files named 19x.WAV and 1Ax.WAV. The x
denotes additional file control attribute characters. See the Filename Formats section below.
Speaker Connection
The speaker terminals on the Main connector provide connections for the two external left and right
speakers. These may be either 4 or 8 ohm speakers, with 4 ohms providing higher output power. The speakers
should be capable of handling up to 25 watts.
NOTE: THE SPEAKER OUTPUTS ARE NOT REFERENCED TO GROUND –
EACH SPEAKER REQUIRES ITS OWN PAIR OF WIRES, AND NEITHER WIRE
MAY BE CONNECTED TO GROUND.

Serial Connector
The CFSound-IV can function as either a RS-232 DTE (Data Terminal Equipment) or RS-232 DCE
(Data Communications Equipment) device. There is a jumper block site on the board labeled JB1 that can be
used to reverse the pins of the signals pairs TxD, RxD and RTS, CTS on the SERIAL connector to
accomplish this change.
DB-9P Signals
Connection to the SERIAL connector requires a female DB-9S mating connector. The following signals
appear on the male SERIAL DB-9P connector:

RS-232 Connection to PC
The PC is configured as a DTE device. A one-to-one, female DB-9S to DB-9S cable can be used to
connect the PC communication port to the CFSound-IV SERIAL connector when the CFSound is configured
as DCE. Only four wired connections are required.
The RTS connection is for optional flow control of the transmit data to the CFSound to prevent over-
flowing the input buffer at higher baud rates. It requires disabling the RS-485 enable in the CFSound
configuration and implementation of flow control on the host device supplying the data to the CFSound.
RS-232 CFSound (JB1 jumpered as DCE) to PC (DTE)
The CFSound-IV can be connected with a one-to-one cable between the CFSound and host PC when JB1
is configured for DCE (default configuration in copper traces on bottom of the board beneath JB1):

NOTE: Be sure to connect both the Ground of the PC or Host computer and the Ground of your +10
→ +18VDC Power supply together!
The RS-485 A+ and B- signals are terminated with a 100 ohm resistor between them. In addition, there is
a 10K pull-up resistor on the A+ signal to +3.3v and a 10K pull-down resistor on the B- signal to Ground, to
put the received data line in an idle state when there is no connection.

Remote Volume Connector
The sound volume level is controlled by two pushbuttons on the front of the CFSound-IV: one for Up
and one for Down. A momentary button press of the Up button raises the volume level, a button press of the
Down button lowers the volume level. Pressing and holding the button for ¼ second starts an automatic
volume increase/decrease until the button is released or the maximum/minimum volume is achieved. The
volume is essentially db linear in sixty-four, 1db increments from 0db → -66db.The current volume level is
‘remembered’ in non-volatile memory on the CFSound-IV and is restored to its last setting upon power-up.
The Up and Down button inputs are also available on the VOL connector along the front edge of the
printed circuit board inside the enclosure. Connecting a momentary button between the input and ground
parallels the operation of the on-board volume controls:

Quick Start
Also refer to the videos on the SUPPORT page of the CFSOUND.COM website.
1. Connect the transformer, speakers and a normally open momentary pushbutton switch to the Main
terminal block. See Main Connector section above for more information.
2. Apply power to the CFSound-IV. With no SD card inserted, the Green LED should flash fast then
slow. See Diagnostic LED Codes section below for more information.

3. Format a SD Flash card using either FAT16 (FAT) or FAT32:

4. Download the sample sounds from the CFSound website:
http://www.acscontrol.com/Downloads/Products/CF/CFSoundIV/CFSound4TestSounds.zip
5. Extract the test sounds onto the formatted SD Flash card. Browse to the SD drive:
6. Carefully insert the SD card into the CFSound-IV. The Green LED should flash fast then go on
steady and the background sounds should start playing then repeating.
7. Press the button. The CFSound-IV should interrupt the background sound, play sound #25, then
resume playing the background sound.

Troubleshooting
No sound, no Green or Red LED(s) flashing
The CFSound-IV doesn’t have correct power. Verify the power supplied to the MAIN connector for the
correct polarity and level using a voltmeter if available. If this is correct, verify that none of the wiring to the
unit is shorted causing the internal resettable fuse to be tripped. Try removing power, waiting for 15 seconds
and reapplying power to allow the internal fuse to reset.
No sound, Red LED flashing
The Red LED is flashing a pattern of one or more numbers to help identify the problem. Please see the
Diagnostic LED Codes and Frequently Asked Questions sections below. Also refer to the videos on the
SUPPORT page of the CFSOUND.COM website.
Low sound volume
Sound volume may be adjusted using the up / down pushbuttons on the front of the unit. Push and hold
the up button to increase. If this doesn’t adjust the volume, verify your speaker wiring and impedance.

Programming the Secure Digital FLASH Card
SD/SD-HC Flash Card Requirements
The Compact FLASH IV Digital Audio System was designed to use only Secure Digital FLASH Cards
(SD or SD/HC Cards) that support the Serial Peripheral Interface mode at 3.3 volt operation. SD-HC cards up
to 32GB may be used. Tested cards include SanDisk, Samsung, Dane-Elec, Memorex and Hitachi. The
SanDisk card was tested, since they manufacture 90% of the retail cards on the market. Secure Digital
FLASH Cards are available in many local electronics or camera stores or can be ordered directly from ACS.
The Secure Digital FLASH Card is programmed by inserting it into a SD Card FLASH adapter
connected to your computer’s USB port. Sound files are copied to the SD FLASH Card just as if it were a
disk drive. The files used are the standard “*.WAV” files typically employed by Windows and DOS audio
applications for years.
When a new SD FLASH Card is first installed into your computer, Windows (95 or later) should
recognize the device and install the software necessary to access the card. After the software installation is
complete, the SD FLASH Card appears as a disk drive icon under My Computer. You may then use
Windows Explorer to drag and drop the sound files from your computer’s hard disk directly to the SD
FLASH Card drive icon. It really is just that easy.
Please take care not to use audio tracks that are copyrighted. If you wish to avoid this issue, you will find
that many computer software outlets have CD’s with non-copyrighted music and audio sound effects that you
may use without limitation. They are commonly found in the multimedia section.
Please be advised that you as the user are solely responsible for audio that you record and
play from the Compact FLASH IV Digital Audio System.
Installing and Removing the Secure Digital FLASH Card
Care should be taken when installing or removing the SD FLASH Card. Please be certain to insert the
card with a straight and level motion. Please do not force the card to insert. Otherwise the SD card socket
may become damaged and the card and/or Compact FLASH IV Digital Audio System may become
unusable.
Before REMOVING the SD FLASH Card from your PC under Windows 95 or later, Microsoft
recommends that you double click on the Removable Drive icon at the bottom of your computer screen. This
will bring up the Removable Drive properties window. Click on the card you wish to remove by clicking on
it. Finally, click on the stop button. Windows will then tell you that the SD card can be safely removed.
Under Windows XP and later OSs you may also right-click on the folder and select Eject.
Failure to stop the card reader and/or eject the SD card after writing to it may result
in incorrect or incomplete data on the card.
On the Compact FLASH IV Digital Audio System this will all happen automatically simply by
removing the card.
Audio Rates Supported
The Compact FLASH IV Digital Audio System supports 8 or 16-bit mono or stereo Windows
PCM format (.WAV) sound files at sampling rates of 8KHz, 11.025KHz, 16KHz, 22.050KHz,
32KHz and 44.1KHz only. The file must be recorded in the PCM WAV format –simply
renaming a MP3 file will not work.

The Compact FLASH IV Digital Audio System reads the sampling rates and formats encoded in the
.WAV sound files whenever a card is first inserted or a sound play-out is triggered. The unit will not play any
file that does not meet these requirements. Further, this error condition should be identified by the red led
flashing twice every six seconds. See the Diagnostic LED Codes section below for more information.
Formatting the SD Card
Secure Digital FLASH cards must only be formatted using the FAT16 or FAT32 file systems. Most SD
cards come correctly pre-formatted for their use in digital cameras and other devices.
SD cards must be formatted as FAT16 or FAT32 file systems.
SD cards formatted as NTFS, Linux EXT3 or other formats are not supported.
Some digital cameras and cellphones incorrectly format their SD cards.
The maximum supported partition size is 32G. The CFSound-IV will attempt to locate a valid, active
partition on the formatted card in order to be able to access the files. SD cards that have been previously used
in some digital cameras may not be correctly formatted, or may not have valid partitions defined.
By default, Windows XP will format any Secure Digital card of 64MB or more with FAT32 format. The
ACS Compact FLASH IV Digital Audio System uses the FAT (FAT16 or FAT32) format and cannot operate
with a NTFS formatted card. You must select FAT or FAT32 file system to format your Secure Digital card
in a Windows XP PC.

The configuration settings may be changed in two ways; a VNC connection to the CFSound-IV’s IP address
with the DEFAULT jumper installed or via an ACS Basic program.

How the Communication Works
The RS-232 SERIAL connection is essentially always connected –even if no physical connection is present.
The USB connection is ‘connected’ when the cable is plugged into a host PC where the driver has been
installed and the CFSound-IV is configured for USB Mode: SERIAL.
The ETHERNET connection is ‘connected’ when the CFSound-IV has been connected to the network and a
TCP/IP raw sockets link has been established.
Incoming data from each of the three sources are combined asynchronously in parallel into the CFSound
input buffer.
Any output that the CFSound generates is copied to all three outputs synchronously. If a connected output
queue fills up, the other outputs are delayed until the full queue has space available - so the slowest connected
output limits the output data rate to all of the outputs.
Note that some USB hosts will stop responding to the USB connection if it is connected and there is no
application running to receive the incoming data –stopping the output data to all of the outputs.
