ACS CFSound-IV Compact FLASH Digital Audio System
May 8, 2017
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
FLASH (SD/SDHC) 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

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 –

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 overflowing 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

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:

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.

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.

Serial Flow Control
CFSound firmware provides optional support for flow control of transmit data to the player to prevent
overflowing the serial input buffer at higher baud rates.
The CFSound will assert its RTS signal on power-up and whenever there is room in its input buffer.
The CFSound will de-assert its RTS signal whenever the input buffer is at 90% of its 2048 byte capacity
or higher.
It will re-assert its RTS signal whenever the input buffer is below 80% capacity.
The host device that the CFSound is connected to should monitor the RTS signal, typically by
connecting it to the host’s CTS input, and only send transmit data to the player when the signal is asserted.
Without flow control it is possible to overrun the CFSound input buffer at baud rates above 9600 baud.
Symptoms of input buffer overflow include missing or incorrectly displayed data or commands.
The following configuration settings determine the CFSound-IV’s serial port operation:

RS-485 Driver Enable
CFSound firmware provides configurable support for enabling the optional factory installed RS-485
transceiver to operate in a half-duplex mode. This allows multiple devices to exist on a multi-drop bus with
devices receiving from the bus when they are not transmitting.
The CFSound will enable its transceiver driver whenever it needs to transmit data, then it will disable the
driver after the data is fully transmitted.
Enabling this option in the configuration menu overrides the Serial Flow Control via RTS above
as it uses the RTS signal to control the RS-485 driver enable.
The following configuration settings determine the CFSound-IV’s RS-485 driver operation:

MAC Address
The Media Access Control address (MAC Address) is a unique identifier assigned to network interfaces
for communications on the physical network segment. Each device on a physical network segment must be
unique amongst all devices on the network segment to allow network traffic to be routed to and from the
correct hardware device. MAC addresses may be assigned universally across all manufactured devices or
locally by the device users. The CFSound-IV supports locally administered MAC addresses – the address is
assigned to the display by the user or network administrator, replacing the configured default address.
The MAC address is 48 bits long and is typically expressed as six groups of hexadecimal digits
separated by colons in transmission order.

Universal and locally administrated MAC addresses are distinguished by setting the second-least
significant bit of the most significant byte of the address – known as the U/L bit. If the U/L bit is zero the
address is universally administered, if it is one the address is locally administrated.

If the least significant bit of the most significant octet is zero the network frame is meant to reach only
one receiving network device (NIC). This type of transmission is called Unicast addressing – the frame is
transmitted to all nodes within the collision domain, which usually ends at the nearest network switch or
router. Only the network device with the matching MAC address will accept the frame.
If the least significant bit of the most significant octet is one each network device will choose to accept
the frame based upon a different criteria other than a matching MAC address; maybe a configurable list of
accepted MAC addresses. This type of transmission is called Multicast addressing.
The CFSound-IV currently only supports Unicast addressing. The default MAC address is
02:01:23:45:67:89 – which configures a Unicast, Locally Administrated MAC address.
The MAC address must be configured to be unique amongst all devices on the network segment that the
CFSound is attached to. As it is locally administrated it is the user’s responsibility to ensure that it is a
unique value.
IP Address
An Internet Protocol address (IP Address) is a numerical label assigned to each device participating in
the network that uses Internet Protocol for communication. The IP Address serves two functions; host or
network identification and location addressing. The CFSound-IV currently supports IPv4 protocol which
requires a 32-bit IP Address number.
The IP Address is a 32-bit binary number, but it is usually expressed as 4 decimal numbers, each ranging
from 0 to 255, separated by dots. Each decimal number represents a group of 8 bits (octet) of the address:

Devices that are not directly connected to the Internet but only use the network to communicate do not
need globally unique IP Addresses. The Internet Assigned Numbers Authority (IANA) has defined three
ranges of reserved, private IP Addresses for these devices:

Private networks typically connect to the Internet through a Network Address Translation (NAT) device
such as a router. The NAT hides a large number of IP Addresses in the private network by mapping TCP and
UDP port numbers on the public network to individual addresses on the private network; the port numbers
are site specific extensions to an IP Address. This allows a large number of devices on the private network to
appear to have a single IP Address on the public Internet.
The CFSound-IV can utilize a static, user-configured IP address/mask or a dynamic NAT assigned IP
address/mask (DHCP client).

IP Mask
A sub-network or subnet is a logically visible subdivision of an IP network. All computers that belong to
the subnet are addressed with a common, identical, most-significant bit-group in their IP Address. This
results in the logical division of an IP Address into two fields; a network or routing prefix and the host
identifier:

Host Identifier
The process of sub-netting involves the separation of network prefix and subnet number portion of the IP
Address from the host identifier. This is performed by a bitwise AND operation between the IP Address and
the IP Mask. The result yields the network address or prefix and the remainder is the host identifier. Here is
an example showing the separation of the network prefix and the host identifier from an IP Address
(192.168.1.200) and IP Mask (255.255.255.0):

The purpose of sub-netting is to divide a network into smaller subnets. This is achieved by designating
some high-order bits from the host part and grouping them with the network mask to form the IP Mask. Here
the previous example is modified by moving two bits from the host part to the IP mask to form four smaller
subnets one quarter the previous size:
Binary form

The host identifier of all zeroes is reserved for the network ID, and the host identifier of all ones is
reserved for the broadcast address, so in general the number of hosts on a subnet is 2 N-2 where N is the
number of bits reserved for the host portion of the address. For a 24-bit prefixed network:

Router IP Address
In computer networking a router is a node that connects two networks – such as a private network and
the public Internet. The host devices on the private network send IP packets addressed to IP Addresses on the
private network by resolving the destination MAC address into a destination IP Address through an Address
Resolution Protocol (ARP) sequence if the MAC address is not already in the host’s cache. The IP packet is
then encapsulated into a physical MAC frame addressed to the destination host.
IP packets addressed outside of the private network range cannot travel directly to the destination.
Instead they must be sent to the router as a gateway to the other network. In order to resolve the MAC

address of the outside device the router’s MAC address is used as the go-between – the outgoing packet is
physically addressed to the router, and the router performs the outside network ARP to handle the physical
message routing.
By definition any packet who’s IP Address network prefix doesn’t match the subnet network prefix of
the private network needs to resolve to the MAC address of the router in order to be directed to the public
network. This configuration item allows that to happen.
FTP Server Port
The CFSound-IV provides a limited File Transfer Protocol (FTP) server capability. FTP is a standard
internet protocol used to transfer files between network hosts. It is built on a client/server architecture and
uses separate control and data connections between the client and server.
If the configured FTP Server Port is non-zero, FTP protocol control request packets will be accepted and
processed. The CFSound FTP Server responds to these requests over the control port with three-digit status
codes and text in ASCII.
The CFSound-IV FTP Server only supports Passive mode and the data port that is used is always one
less than the control port.
The server only supports anonymous logins with no password support.
Only one data transfer command at a time is supported.
The following FTP Commands are supported:

The CFSound-IV provides limited Virtual Network Computing (VNC) server capability. VNC is a
graphical desktop sharing system that uses the Remote Frame Buffer (RFB) protocol to remotely control
another computer. It transmits the keyboard and mouse events from the client to the server, relaying the
graphical screen updates from the server back to the client over a network connection.
The CFSound-IV implements a ‘virtual display’ – screens can be displayed and interacted with by VNC
connection only. In CFSound Mode the configuration screen is displayed. In Basic mode graphic commands
can be used to display on and interact with this virtual screen which can only be observed via a VNC
connection.
If the configured VNC Server Port is non-zero, RFB protocol messages will be exchanged over that port
to establish and update a VNC session between VNC client software on a PC and the CFSound acting as a
VNC server.
No passwords or authentication are supported. The server reported protocol is RFB 003.003.
Supported graphical update formats are 16-bit R5G6B5 or 32-bit R8G8B8A8. This is negotiated during
the connection phase.
Received mouse events are translated are translated to virtual touchscreen events; Press, Move, Release.
Received keyboard events for keys that have an ASCII code equivalent including Backspace, Tab,
Escape and Enter are processed upon key down only – key up and all other keys are ignored.
Here’s an example using the free program Tight VNC to connect to the CFSound:

HTTP Server Port
The ACS CFSound-IV has the ability to serve HTML pages from the SD card. If the configured HTTP
Server Port is non-zero then HTTP GET requests for SD card resident files will retrieve the file contents.
The server only responds to HTTP GET requests. The file path should immediately follow the IP
Address:
GET /pathToFile
If the GET is followed by a slash/space “/ “ with no filename, an attempt is made to return the file
“index.html” off of the card.
If the requested file is found and opens OK on the SD card a 200 response is returned:
HTTP/1.0 200 OK
Server: http://www.cfsound.com
Connection: close
This is immediately followed by a content type header determined by the requested file’s extension:
File extension
Returned Header
no extension
.htm, .html
.css
.png
.gif
.jpg
.bmp
any other extension
Content-type: application/octet-stream
Content-type: text/html
Content-type: text/css
Content-type: image/png
Content-type: image/gif
Content-type: image/jpeg
Content-type: image/x-ms-bmp
Content-type: text/plain
The content type header is followed by an empty line, then the requested file’s contents.
If the requested file doesn’t exist or can’t be opened on the micro SD card a 404 response is returned:
HTTP/1.0 404 Not found
Server: http://www.cfsound.com
Connection: close
This is immediately followed by the contents of file 404.html if it exists on the card.
TCP/IP Raw Port
The ACS CFSound-IV has the ability to send and receive its serial data stream using TCP/IP raw
sockets. Normally network traffic between two ports is encapsulated using an agreed upon protocol which
may include message headers and other information required by the application. With raw sockets the data is
sent / received un-encapsulated with no accompanying headers or other information.
If the configured TCP/IP Raw Port is non-zero a remote connection to that port allows the remote end to
send data and received data to and from the CFSound as if over the conventional serial port.
In the BETA software the TCP/IP Raw configuration items have been renamed to TELNET and the
code has been modified to work full-duplex. To support full-duplex operation the TELNET port now
sends the <IAC> <DO> <suppress go ahead> command to the caller upon connection.

To connect to the CFSound-IV using TeraTerm and TELNET specify the TCP/IP connection using
the CFSound’s configured IP address and TELNET port:
NTP Client
The ACS CFSound-IV has the ability to synchronize its Real Time Clock (RTC) from a remote time
server using the Network Time Protocol (NTP). NTP is a networking protocol for clock synchronization
between computer systems over packet-switched, variable latency data networks.
There are published lists of NTP time servers, and the selected server should be geographically close. If
at all possible the use of a local NTP server on the private network is strongly recommended to avoid
overloading the public time servers. Windows XP for example can be configured to act as a NTP server.
Some NAT routers can also be configured to provide NTP support.
The use of a remote time server external to the private network requires a correctly configured Router IP
Address in order to perform the ARP for the requisite outgoing UDP packets.
NTP Server
This configuration item should be set to the IP address of the remote NTP time server.
NTP Client Port
If the configured NTP Client Port is non-zero and the NTP Server address is correctly addressing an IP
Address hosting a NTP Server the CFSound-IV will attempt to sync its Real Time Clock to the time server
after reset or power-up. No direct indication of successful synchronization is provided, however the RTC
defaults to Tuesday, January 1, 2013, 12:00AM after reset or power-up.
Local Timezone
By definition, NTP servers provide Coordinated Universal Time (UTC). In order to compute the correct
time the local time zone (offset hours from UTC) must be configured. For example; Eastern Standard Time is
-5 hours from UTC.
Daylight Savings
In addition to the time zone offset from UTC correct local time requires knowledge of whether the
location of the CFSound-IV is currently operating under Daylight Savings time. Setting this configuration
item to Yes adds one hour to the computed local time.

Art-Net™
“Art-Net™ Designed by and Copyright Artistic Licence Holdings Ltd”
The CFSound-IV can operate as an Art-Net peer device to send and receive DMX512 data using an
external Ethernet to DMX adaptor – such as the ENTTEC ODE:
http://www.enttec.com/?main_menu=Products&pn=70305
The CFSound-IV Artistic Licence OEM code is 105016.
The ACS Entertainment Services and Technology Association (ESTA) Manufacture ID is 08F916.
Art-Net IP Port
If the configured Art-Net IP Port is non-zero the CFSound-IV will send an ArtPollReply packet upon
power-up or reset or upon receipt of an ArtPoll packet and then send ArtDmx packets every 4 seconds or
whenever the DMX data generated by the CFSound mode or Basic mode changes at up to a 50mSEC rate.
The Art-Net Universe, Sub-Net and Net are configurable via the configuration settings. The target IP
address defaults to 255.255.255.255 and is also configurable to support a directed broadcast or full IP
address. Note that some Ethernet routers block directed broadcast packets.
In the BETA software, the changed DMX data is sent at up to a 25mSEC rate.

Modes of Operation
The CFSound-IV can operate in one of two different modes:
1.
Conventional CFSound operation where the sound play-out is controlled by the association of
contact numbers and sound filenames. This is referred to as the CFSound Mode.
2.
Scriptable CFSound operation where the sound play-out is controlled by the execution of ACS
Basic programs. This is referred to as the Basic Mode.
Upon power-up, reset or whenever a Secure Digital Flash card is inserted or removed, the unit
determines its operating mode as follows; As the CFSound-IV scans for a SD card, and then files on the card,
the Green LED flashes 3 times per second:
If a SD card is not present, the unit runs in Basic Mode by starting the ACS Basic interpreter and
accepting/executing a subset of Basic commands that don’t require file I/O via the serial port. The Green
LED flashes once per second.
If a SD card is present, the unit looks for a file named CFSOUND.BAS and, if found, starts the ACS
Basic interpreter, loading the file and executing the Basic program within in Basic Mode. The Green LED
flashes once per second.
If a SD card is present, and the file CFSOUND.BAS is not found, the unit scans the card looking for
sound files that follow the conventional CFSound Mode Filename Format. If at least one correctly named,
valid sound file is found, the unit runs in CFSound Mode. If no valid sound files named in the conventional
CFSound Mode Filename Format are found, the unit starts the ACS Basic interpreter and accepts/executes
the complete set of Basic commands via the serial port.

These two modes of operation are detailed in the following sections. Any errors encountered while
scanning the SD card produce error code flashes on the Red LED. See the Diagnostic LED Codes section
below for more information about LED error codes.
CFSound Mode
In CFSound Mode, the operation of the CFSound-IV is controlled by the names of the sound files on the
SD card. Sounds are associated with contacts by the leading numeric portion of the filename, and the
controlling state of the contact is specified by additional trailing non-numeric character attributes. Sounds
may be played when a contact closes, opens, or only while a contact is closed or open. Sounds may be
flagged as non-interruptible, or to only play when no other contact controlled sounds are playing. In addition,
a small configuration text file may be placed onto the SD card along with the sound files to further control
how the unit plays sounds (see the CFSOUND.INI section below).
Filename Formats
The filenames of the individual Sound files on the Secure Digital FLASH Card control how and when
the sounds are played out by the Compact FLASH IV Digital Audio System. The filename must follow the
DOS 8.3 naming convention – up to 8 characters of name with up to 3 characters of extension.
The filenames must start with an number which may be the contact input they are
associated with expressed as a two digit HEX number.
All letters in the filename must be upper-case.
A HEX numeric digit is 0 through 9 and A through F, with 0 being equal to decimal 0, A being equal to
10 and F being equal to 15. The first digit (MSB) of the two digit hex number is multiplied by 16. The
second digit (LSB) is added to the adjusted value derived from the first digit. The number 10 in HEX is thus
equal to 16 decimal. The number 20 in HEX is 32 decimal, 21 in HEX is 33 decimal, and 7F in HEX is 127
decimal. For your convenience, a decimal to hex conversion table is provided below:

ACS CFSound-IV Compact FLASH Digital Audio System

For example, a sound file associated with optional contact input #1 would be named “01.WAV,” a sound
file for input #10 would be named “0A.WAV,” a file for input #16 would be “10.WAV” and a file for input
#36 would be “24.WAV”. There is no input #0 and so “00.WAV” is reserved and should not be used.
There is a maximum of 254 sounds so “FF.WAV” is reserved and should not be used.
The two digit hex input number must be the first two characters in the filename.
Additional letter tokens are appended to the input # in the filename to determine when and how the
audio sound is played. The Compact FLASH IV Digital Audio System provides two inputs in its standard
configuration and, by adding optional boards, can be expanded to 10, 18, 26 or 50 total inputs. The inputs
can be wired to switches or other such devices, either normally opened or normally closed.
You can also connect the RS-232 port of the Compact FLASH IV Digital Audio System to the RS-232
port of your computer or PLC to control up to 254 sounds using serial commands.
The filename letter tokens are described as follows:
If a “C” appears after the hex number in the filename, the sound file will be played on a Closure of the
corresponding optional contact input module input or serial command. The sound will start playing when the
associated contact input goes from an open to closed state.
If an “O” appears after the hex number in the filename, the file is played on an Opening of the
corresponding optional contact input module input or serial command. The sound will start when the
associated contact input goes from a closed to an open state.
If a “P” after the hex number in the filename, the file will play only while the “C” or “O” state is true. If
“C”, it will play while the associated contact input is closed and it will stop playing the sound when the input
is opened. If “O”, it will play while the associated contact input is open and it will stop playing the sound
when the input is closed.
If an “R” appears in the filename after the hex number, the sound is repeated, that is to say that the same
sound file plays over and over. If used in conjunction with the “P” command, the sound file will repeat the
entire time the “C” or “O” input condition is true. If “C”, the entire time the input is closed, if “O”, the
entire time the input is open. If triggered without a “P” attribute, the file will play indefinitely or until
another sound is played.
If an “S” is used in the filename after the hex number, the on-board Push-To-Talk (PTT) relay and
contact closure corresponding to the input number on an optional plug-in board will be activated when the
file is played.
If a “B” is used in the filename after the hex number, the sound is considered to be a background sound.
Background sounds play when no other sound is playing, and multiple background sounds are played in the
numerical sequence of the two digit input number. Sounds that are marked as Background may not be
marked for contact closure or opening, play while or repeat. Such markings will be ignored.
If an “N” is used in the filename after the hex number, the sound is considered to be a non-interruptible
sound. Sounds that are marked as non-interruptible will play to completion before any other sounds are
played. Contact events that occur while non-interruptible sounds are playing are discarded unless the
SaveNIContacts entry in the optional CFSOUND.INI file [Contacts] section is set to TRUE. Sounds that are
marked as non-interruptible may not be marked for Repeat or as a Background sound. Such markings will be
ignored.
If an “F” is used in the filename after the hex number, the sound is considered to be associated with a
DMX channel Fade. Sounds that are marked for fade will ramp up the associated DMX channel value
between the BeginFadeValue and EndFadeValue entries at the FadeDuration rate in the CFSOUND.INI
file [DMX] section when the sound plays and ramp down when the sound ends or another sound is started.
If a “D” is used in the filename after the hex number, the sound is considered to be associated with one
or more DMX channels defined by an associated scene ##.DMX file.

After the filename letter tokens a space, dash or underscore separator may be followed by a short text
description.
Sample Filenames
“01C.WAV”
This file would play once, when triggered by optional contact input #1 closing.
“02O.WAV”
This file would play once, when triggered by optional contact input #2 opening.
“04CP.WAV”
This file would play once, when triggered by optional contact input #4 closing and
play only while input #4 was closed without repeating.
“07CPR.WAV”
This file would play and repeat, the entire time optional contact input #7 was closed.
“01OPR.WAV”
This file would play and repeat, the entire time optional contact input #1 was open.
“08CNS.WAV”
This file would play once, without being interrupted when triggered by optional
contact input #8 closing. The on-board PTT relay would be activated for the duration
of the sound as well as optional contact output #8.
“7EB.WAV”
This file would play as a background sound whenever any other sound was not
playing.
“7FB.WAV”
This file would also play as a background sound after the preceding file 7EB.WAV
had played.
“19C.WAV”
This file would play once, when triggered by contact input #25 on the MAIN
connector on the back of the CFSound-IV closing.
“01CD.WAV”
This file would play once, when triggered by optional contact input #1 closing. When
the sound starts, the first 16 DMX channels would be set to values in the 01.DMX
file’s [SoundStart] section, when the sound stops, the first 16 channels would be set to
values in the [SoundStop] section of the same file.
“19CF.WAV”
This file would play once, when triggered by contact input #25 on the MAIN
connector on the back of the CFSound-IV closing. When the sound starts, DMX
channel #25 would fade-up to values at a rate determined by entries in the
CFSOUND.INI file. When the sound stops DMX channel #25 would fade-down.

Secure Digital FLASH Card Loading and Scanning
Once programmed with the desired sounds and correct filenames, the card is inserted into the slot on the
front of the Compact FLASH IV Digital Audio System. The green LED indicator should begin to flash
indicating that the unit is scanning and loading the files from the card. When the card is correctly loaded and
scanned, the green LED should glow steadily. Any problems encountered while reading the SD card are
indicated by a repeating sequence of flashes on the red LED indicator (see the Diagnostic LED Codes
section below for more information).

The card may be removed at any time. In that case, both the green and red LED indicators should turn
off, then the Basic mode is started.
The optional contact inputs are ‘debounced’ by sampling them using a periodic interrupt. The sample
rate is 50 Hertz (20 milliseconds). Valid input closures are detected by reading a 0 - 0 - 1 (open, open,
closed) sample sequence. Valid input opens are detected by reading a 1 - 1 - 0 (closed, closed, open) sample
sequence.
The status of the unit while loading and scanning is also displayed via messages sent out the serial port.
Using a PC with “Tera Term”, “HyperTerminal” or other terminal emulator software connected to the
Compact FLASH IV Digital Audio System serial port the card loading and scanning messages may be
viewed. The serial data format defaults to 9600 baud, 8 data bits, 1 stop bit and no flow control. Samples of
these messages are shown in the Appendix.
Background Audio Tracks
Sounds labeled with the “B” token in their filename after the hex number are played in numerical
sequence as background sounds when no other audio tracks are being played, continuously repeating the
sequence. A background audio track will cease playing when any other sound file is triggered to play by
contact closure or serial command. Once that sound file is finished playing, the background audio file that
was playing will resume playing from the point where it was interrupted and continue to play until again
interrupted.

CFSOUND.INI File
Support is provided to control various operating parameters by the inclusion of a CFSOUND.INI file on
the SD card. This file is a text file that is created using Notepad or other text editor and then is placed onto
the SD card along with the sound files.
When a card is inserted and after all sound files have been loaded, the CFSound-IV unit looks for a file
with this name, and reads initialization parameter entries from it. Parameter entries are organized into
sections with a section name in brackets followed by one or more PARAMETER=VALUE lines. The Section
Names and Parameter entries are case sensitive. A section or parameter may be commented out by placing a
‘#’ character as the first character on the line. The last line in the file should be a blank line.
THE CFSOUND.INI FILE IS NOT REQUIRED IF YOU ARE NOT ALTERING A PARAMETER
FROM THE DEFAULT VALUE SHOWN IN THE TABLE.
SECTIONS AND PARAMETERS THAT ARE NOT BEING CHANGED FROM THEIR DEFAULT
VALUES IN THE TABLE ARE ALSO NOT REQUIRED TO BE IN THE FILE.
INCLUDING A [DMX] SECTION AND PARAMETERS WHEN THE DMX MODULE IS NOT

causes the new behavior wherein the
contact's current status is sampled upon
reset, power-up or card-insertion. This
will cause no associated sound activation
until the contact is re-activated.
Default=FALSE.
Sets the number of the contact that will
play sounds in sequence to the decimal
value dd.
Default=0 (no sequencing)
Sets the first sound number that will be
played in sequence to the decimal value dd.
Default=1 (sound #1)
Sets the last sound number that will be
played in sequence to the decimal value dd.
Default=127 (sound #127)
Setting this value to TRUE will remember
any contact events that occur while a noninterruptible sound is playing. Note that
this can cause a non-interruptible sound to
play again if its contact is re-activated
while it is playing.
Default=FALSE
Setting this value to non-zero will cause
the output contacts associated with sounds
to repeat on the modulo value if
QuizMode=FALSE.
Example: OutputContactModulus=4 activates
contact outputs 1 through 4 for sounds 1
through 4, contact outputs 1 through 4 for
sounds 5 through 8, etc.
Default=0
Setting this value to TRUE will cause each
activation of the SequenceContactNumber to
play a random sound from the range
FirstSoundNumber to LastSoundNumber.
Default=FALSE
Sets the number of the contact that will
offset the sounds associated with the other
contacts by ContactOffsetAmount to the
decimal value dd. Does not affect Sequence
or Quiz mode.
Default=0 (no offset)

Quiz / Kiosk Mode
The CFSound-IV may be configured to operate in a Quiz or Kiosk mode. This mode is enabled by
including the requisite [Quiz] section entries in a CFSOUND.INI file on the card with the
QuizMode=TRUE parameter.
In Quiz mode, Question contacts trigger the Question sounds, then Answer contacts trigger the Answer
sounds related to the question that was activated. The Question contacts start at contact 1 and are contiguous
through the number of QuestionContacts=dd parameter. The Question sounds would be named 01C.WAV,
02C.WAV, … , xxC.WAV where xx is the hexadecimal equivalent of the QuestionContacts=dd parameter.
The Answer contacts immediately follow the Question contacts and are contiguous through the number
of AnswerContacts=dd parameter. Each Answer contact is associated with an array of Answer sounds, with
the offset into the array controlled by the Question contact that was activated. There is also an additional
timeout Answer sound that will be played if an Answer contact is not activated within the
NoAnswerTimeout=dd seconds interval.
Due to the maximum number of sounds being limited to 255 the following limitation must be observed:
QuestionContacts x (AnswerContacts + 1) <= 254
The next table shows a sample of Quiz mode sound file names and their contact associations given the
following values for the [Quiz] section parameters: QuestionContacts=4, AnswerContacts=4,
AnswerWithoutQuestionSound=7E and AwaitAnswerSound=7F in the CFSOUND.INI file. Notice how

There are two additional, optional sounds that may be played in Quiz mode. The
AwaitAnswerSound=xx parameter, if xx is non-zero, causes sound file xx.WAV to be played after the
question sound while awaiting an Answer contact activation. In the preceding example, this would play
sound file 7F.WAV. The duration of this optional sound or the NoAnswerTimeout=dd seconds parameter,
whichever is greater, determines the interval before the associated no answer timeout sound file is played.
The AwaitAnswerSound should not be marked as non-interruptible.
The AnswerWithoutQuestionSound=xx parameter if xx is non-zero causes sound file xx.WAV to be
played if an Answer contact is activated before a Question contact to prompt user to select question first. In
the preceding example, this would play sound file 7EC.WAV when any Answer contact is activated before a
Question contact.
A Kiosk mode of operation may be obtained by setting the NoAnswerTimeout=dd parameter to zero.
This effectively disables the AwaitAnswerSound and all of the No Answer Timeout sounds simply
allowing the Question contact to select different sets of Answer contacts sounds such as various languages or
features. After a Question contact is activated, it remains active selecting a given set of Answer contact
sounds until another Question contact is activated.
Contact outputs may also be activated for Question and Answer sounds by using the ‘S’ token in the
filename. In Quiz mode, Question contact outputs remain active for the duration of the Question/Answer
cycle. In Kiosk mode, the last Question (answer selection) contact output remains active until another
Question input is activated. Note that the Answer contact outputs associated with the Answer contact inputs
are used for each set of answers, independent of which Question contact is activated. Unique Answer contact
outputs may be achieved by constructing a matrix using the Question contact outputs as Rows and the
repeating Answer contact outputs as Columns (or vice versa). This is shown in the following diagram:

Sequential Sound Play-out
The CFSound-IV may be configured to allow a single contact closure (or opening) to play several
sounds in sequence; one each time it is closed (or opened). This mode is enabled by including the requisite

[Contacts] section entries in a CFSOUND.INI file on the card with the SequenceContactNumber=dd
parameter set to a non-zero, valid contact number from 1 to 8 (1 to 24 with Contact Sense 24 module) or 25
and 26 (rear of unit contact inputs).
Only a single sequence triggered from a single contact input is supported in CFSound mode – for
multiple sequences triggered by multiple contacts the unit must be scripted in ACS Basic.
The range of sounds that may be played in sequence may be constrained by the addition of two other
parameter entries in the [Contacts] section. The FirstSoundNumber=dd parameter controls the starting
sound number of the sequence, and the LastSoundNumber=dd parameter controls the ending sound number
in the sequence. Setting the FirstSoundNumber parameter to a higher number than the LastSoundNumber
will cause the sounds to be played in reverse sequence, higher number to lower number. The sequence wraps
around to the beginning or end.
For example to play normal sounds on the first 8 contacts, and sequence through 16 different sounds for
the 25th contact, a card would be prepared with the 24 sound files named 01C.WAV – 18C.WAV. Then a
CFSOUND.INI file would be added to the card with the entries:
[Contacts]
SequenceContactNumber=25
FirstSoundNumber=9
LastSoundNumber=24
The first eight contacts would each play their associated sound. Each closure of contact 25 would play a
sound from the 09C.WAV – 18C.WAV group then repeat from 09C.WAV – 18C.WAV in sequence. To
reverse the order of the sound play-out set the FirstSoundNumber=24 and the LastSoundNumber=9.
To cause the entire sequence of sounds to be played once whenever the SequenceContactNumber is
activated, set the AutoplayEntireSequence parameter to TRUE. For example a museum exhibit needs to
play a sequence of 8 sounds when triggered with each sound activating a relay output while it is playing. A
SD card would be prepared with the 8 sound files in the sequence named 01CNS.WAV – 08CNS.WAV.
Then a CFSOUND.INI file would be added to the card with the entries:
[Contacts]
SequenceContactNumber=25
FirstSoundNumber=1
LastSoundNumber=8
AutoplayEntireSequence=TRUE
Whenever contact 25 is closed, the eight sounds 01CNS.WAV – 08CNS.WAV would play in sequence,
each sound activating its output relay. This feature only works for non-random sequences. The addition of
the non-interruptible attribute to the file names prevents multiple contact 1 closures from prematurely
advancing the sequence.

RS-232 Serial Port Protocol
Sound play-out may also be controlled via commands received via the serial port. The data format is the
current baud rate (default is 9600 baud), 8 data bits, 1 stop bit and no flow control.
Sounds may be started, queued and stopped using a simple ASCII protocol. The SOH/ETX protocol
starts each command with a single ASCII Start of Header control character = 01 16 or CTRL-A, represented
herein as <SOH> and ends each command with a single ASCII End of Text control character = 03 16 or
CTRL-C, represented herein as <ETX>.
The actual command is determined by the next lower-case ASCII character following the <SOH>:
Command character:
Commands to:

<SOH>p&1A<ETX><SOH>p&30<ETX>
Stop playing the current sound and flush the queued sounds:
<SOH>p!00<ETX>
Up to 128 sounds may be queued. Sounds that are queued are played in succession in the order that they
were queued only when no other sound is playing until the queue is exhausted or flushed. Note that this can
occur at the end of the current background sound file before it repeats. A background or other sound that is
playing may be stopped by issuing a “<SOH>p-00<ETX>” serial command sequence to allow queued sounds
to be heard. The background sound will be resumed when the queue has emptied.

DMX Operation
The CFSound-IV can be configured to be a DMX controller (Master) or DMX device (Slave). DMX
operation is provided via the ArtNet™ protocol over Ethernet and an external Ethernet to DMX converter.
DMX operation is controlled by the CFSOUND.INI file IsMaster parameter as well as the presence of the
DMX Scene or Fade filename attributes.
DMX Controller (Master)
The CFSound-IV becomes a DMX controller (Master) when it finds files on the SD card with the DMX
Scene or Fade filename attributes, OR, when it reads the CFSOUND.INI file and finds a [DMX] section with
the IsMaster parameter set to TRUE (see the Filename Formats and CFSOUND.INI sections above). As a
DMX controller the CFSound produces the ArtNet Ethernet packets that commands connected DMX devices
to brighten/dim, move, pan or otherwise respond to their DMX channel values.
When a sound is played with the filename Fade attribute, the CFSound begins a fade-up of the channel
value with the same number as the sound. When the sound stops playing a fade-down of the channel value
occurs. The beginning and ending channel fade values as well as the fade duration can be controlled by
entries in the CFSOUND.INI file.
When a sound is played with the filename Dmx scene attribute, the CFSound sets the first 32 channels to
values obtained from an associated ##.DMX file – the ## must match the two character sound number of the
associated ##CDx.WAV or ##ODx.WAV file. The content of the .DMX text files follow a similar format as
the CFSOUND.INI file:

DMX Device (Slave)
The CFSound-IV becomes a DMX device (Slave) when it finds no files on the SD card with the DMX
Scene or Fade filename attributes, OR, when it reads the CFSOUND.INI file and finds a [DMX] section with
the IsMaster parameter set to FALSE (this is the default, see the Filename Formats and CFSOUND.INI
sections above). Using the ArtNet™ protocol and external Ethernet to DMX device the CFSound monitors
the received ArtNet data packets for DMX channel values.

The CFSound-IV monitors a group of three channels, starting at the channel selected by the
SlaveBaseChannel parameter of the CFSOUND.INI file for changes in value. Sounds may be stopped,
started and queued by setting the DMX Sound Number channel value to the desired sound number and
toggling the DMX Command channel value between 0 (no operation) and one of the other command values:
DMX Channel Number

Description
SlaveBaseChannel + 0
Command
SlaveBaseChannel + 1

0 = No operation
1 = Play Sound Number
2 = Stop playing Sound Number
3 = Queue Sound Number
4 = Clear queue
5 = Stop playing and clear queue
6 = Mute amplifier
7 = Un-mute amplifier
0 to 254
When stopping 0 = all sounds
0 to 255
Up to 128 sounds may be queued. Sounds that are queued are played in succession in the order that they
were queued only when no other sound is playing until the queue is exhausted or cleared. Note that this can
occur at the end of the current background sound file before it repeats. A background or other sound that is
playing may be stopped by issuing a ‘stop playing all sounds’ command sequence to allow queued sounds to
be heard. The background sound will be resumed when the queue has emptied.
Sound volume may also be controlled by changing the value of the DMX Volume channel. The 256
channel values are mapped to the 64 volume values by dividing the channel value by 4. The resulting volume
is essentially decibel linear in sixty-four, 1db increments from -66db (value of 0) → 0db (value of 63). The
current volume setting is not ‘remembered’ by the CFSound between power-up, reset, or SD card insertions.
Note that the volume push buttons on the front of the unit will appear to not work since their ‘settings’ are
constantly being over-ridden by received DMX frames containing a received volume setting.
Here’s an example - CFSOUND.INI file contains:
[DMX]
SlaveBaseChannel=50
Initially DMX channels SlaveBaseChannel+0 through SlaveBaseChannel+2 should be set to zero. This
is the no operation command, with the volume set to minimum:

Basic Mode
In Basic Mode, the operation of the CFSound-IV is controlled by the interpreted execution of a user
written program that is written in the ACS Basic language. BASIC is the acronym for Beginners’ Allpurpose Symbolic Instruction Code – an easy to learn programming language developed by Kemeny & Kurtz
at Dartmouth in 1964. Programs consist of numbered lines with one or more English keywords describing the
operations that the user wants to have performed.
The BASIC interpreter built-in to the CFSound-IV implements most of the language elements for
working with integers, strings and files as well as providing access to the CFSound-IV hardware features
such as contacts, timers, clock and playing sounds. The language elements are outlined in the separate
document “CFSound-IV Basic Programming” available for download on the CFSound website.
Programs may be developed two different ways:
1.
Interactively using a terminal emulator such as Windows HyperTerminal or TeraTerm
connected to the CFSound-IV’s serial port.
See the “Upgrading the Firmware” section at the end of this manual for a description of the
required cabling and terminal emulator settings.
This is the preferred development methodology.
2.
Offline using a text editor such as Windows Notepad. The files are then saved onto the SD card
for debugging when inserted into the CFSound.
This methodology is slow, cumbersome and error-prone since it is not interactive and
errors cannot be viewed or addressed in-situ and is not recommended.
Once a program has been interactively developed and tested, it may then be placed or saved onto the SD
card named as CFSOUND.BAS along with any other required files. The CFSound will then load and execute
this file upon power-up, reset or SD card insertion, effectively customizing the unit’s function.

Power Requirements
The idle current of a CFSound-IV unit, no expansion modules with a 4GB SanDisk SD card installed is
~80mA @ 12VDC input.
With a background sound playing at a moderate level, the current consumption averages ~200mA @
12VDC.
Digital Audio Recording
Initially make all recordings (either music or voice) with a sample rate of at least 44.1KHz and 16-bit
mono or stereo. This high quality, first-generation recording will later provide the greatest bandwidth and
produce the best sounding final audio.
Recommended Recording Procedure
1.
Record any audio clip of your choosing @ 44KHz, 16-bit, Mono or Stereo. Make sure that your samples
do not clip (go above or below the sample window). The peaks of your audio clip, should, however, fill
vertically at least 95% of the sample window. If they do not, you will need to boost your input signal by
using a pre-amp or by some other means.
2.
Edit the clip until satisfied. You can use a sound editor or filter program, such as Syntrillium’s Cool
Edit to normalize the amplitude of the sample. Use this command cautiously though, since it also tends
to amplify noise levels. It is always preferable to re-record your sound clip at a higher level to achieve
better fidelity.
It is imperative that all initial editing and filtering be done to the audio clip while it is formatted at 16bit stereo and 44.1KHz. Please be certain that your recording environment is absolutely quiet. Recordings at
8-bit or other sample rates can be played as-is or up-converted using suitable software.
Also remember that digital play-out devices do not introduce any static of their own other than
quantization noise. They only play back exactly what was recorded. If there is excessive static in the audio
clip or sample, then there was probably static in it originally.
Please see the videos on the SUPPORT page of the CFSOUND.COM website for additional information.
Self-Recording Procedure
The CFSound-IV has the ability to self-record audio presented at the line-level inputs into a contact
associated .WAV file on the SD card. This requires a freshly formatted relatively fast SD card to operate
properly – slow or fragmented SD cards may cause glitches in the recordings.
1.
Connect your audio source to the CFSound line-level inputs. The audio level must be adjusted externally
to avoid low volume and/or clipping in the recording.
2.
Press and hold both CFSound volume up/down buttons. After about half a second the Green and Red
LEDs underneath the SD card should begin toggling back and forth indicating that the recording process
is Armed. Once the LEDs start toggling, the volume buttons may be released. On a freshly formatted SD
card, the buttons would need to be held during Reset/Power Up to prevent Basic from starting since there
are no contact named .WAV files on the card.
3.
Now close and hold the contact that the recording is to be associated with. The Red LED should stay on
solid while the Green LED continues to blink - indicating that the CFSound is recording. When the
contact is opened the recording will stop, the Red LED will go out and the file will be renamed to
associate it with the contact closure. Problems during or after the recording are indicated by a flashing
Red LED error code. Pressing the contact again should play back the recorded sound.

Contact Wiring
On the optional Contact Modules, switch contacts are wired between the Input pin number and a ground
located on either end of the connector. The inputs are optically isolated using optocouplers. The cathodes of
the LEDs in the optocouplers are connected to the Input connector port pins. The Anodes of the LEDs in the
optocouplers are connected to an internal 12VDC power supply, with a 680 ohm current limiting resistor in
series. The output transistor of each optocoupler has a 10K pullup resistor on its collector, with the emitter
connected to ground and is buffered by an inverting gate. The following diagram is representative of one
input:
+5v
+12v
10K
ohm
680
ohm
INPUTx
GROUND
An input is activated by sinking current from the corresponding input pin to ground. A Ground
connection is supplied on pins 1 and 10 of each Input connector for this purpose. The input current sink
requirement is approximately 15 mA.
Switches may be one of two forms: Normally Open (N.O.) or Normally Closed (N.C.). Switches that are
Normally Open have no electrical connection between the switch terminals unless the switch is activated
closed. Switches that are Normally Closed have an electrical connection between the switch terminals unless
the switch is activated open.
The CFSound-IV Contact Modules can work with either form of switch by using the appropriate
filename letter token in the filename. A sound can be played when a Normally Open switch closes by
placing the ‘C’ letter token after the sound number in the sound filename. In a similar fashion, a sound can
be played when a Normally Closed switch opens by placing the ‘O’ letter token after the sound number in the
sound filename.

Connecting Multiple Speakers
The CFSound-IV can play different audio clips to different speakers, one at a time. This requires
monaural audio clips and one or two Contact I/O 8 modules.
The sound files have the ‘S’ attribute in the filename to activate the associated output contact. One
speaker output is then directed to the desired speaker by connecting it through the output contact. The other
side of all the speakers is wired in common but may not be grounded. Here’s a wiring diagram:

To play a sequence of sounds with associated LED illumination, one every time that the button is
pushed, name the sounds 01CSN.WAV, 02CSN.WAV, … , 08CSN.WAV.
Add a text file CFSOUND.INI with the following lines onto the SD card along with the sound files:
[Contacts]
SequenceContactNumber=25
FirstSoundNumber=1
LastSoundNumber=8
Be sure to leave a blank line at the end of the file so that the CFSound can ‘see’ the last line of text.
Now, every actuation of the button will play the next sound in the sequence, without being interrupted,
and the associated LED illuminates while the sound is playing.
To make the CFSound play the entire sequence of sounds when the button is pushed, add the additional
entry to the CFSOUND.INI text file in the [Contacts] section:
AutoplayEntireSequence=TRUE
See the Sequential Sound Playout section above for more information.

Light LED while Sound is Playing
The CFSound-IV has a PTT (Push-to-Talk) relay that can be optionally activated while a sound is
playing. The PTT relay contacts are available on the MAIN connector and can be thought of as a switch that
can be closed when a sound is playing.
The LED is wired as shown – note that the PTT contacts are simply wired in series with the LED and its
power supply:

Frequently Asked Questions
Q. The RED LED repeatedly flashes four times at power up?
Q. The RED LED flashes two times when I try to play a sound, and no sound plays? Why is my
CFSOUND.INI file not making the CFSound-IV perform using the features I have specified ?:
This is by far our most commonly asked question. 99% of time, it is because your files have double
extensions. I.E. "01C.WAV.WAV" or "CFSOUND.INI.INI". Later versions of Windows hide the file
extensions in Explorer, so by putting ".WAV" or ".INI" in the filename, you are actually causing a duplicate
file extension.
To turn the hiding of file extensions off in Windows XP, do the following:
Click on Start
Then Click on Control Panel
Next, Click on Folder Options
Click on the View tab on the Folder Options Window
Scroll down to "Hide Extensions for Known File Types"
Click on the Check box to the left of it to remove the check mark
Click on the Apply Button
Now the complete file names will be displayed in Explorer, and any folder, and you can remove the duplicate
file extensions. Please see the videos on the SUPPORT page of the CFSOUND.COM website.
Q. What Inputs and outputs are available on the main CFSound board, without adding I/O Modules ?:
The CFSound main board has a single PTT(Push To Talk) Relay for an output and two contact inputs that
appears as Contact #25 & #26 for inputs. Additional Inputs and outputs are added by adding I/O Modules.
The CFSound-IV revision 2 can accept one I/O module, the CFSound-IV revision 3 can accept two I/O
modules.
Q. I have a motion sensor tied to an old industrial looping tape deck. The first time the sensor is
broken it will play the first of three tracks, the second time the same sensor is broken it plays the
second track on the tape and the third time it plays the third track. Can your machine duplicate this
task ?:
Yes, the CFSound-IV can function as you described. You make three entries into the [CONTACTS]
section of the CFSOUND.INI file that you place on the Compact Flash Card.
[Contacts]
SequenceContactNumber=dd
FirstSoundNumber=ff
LastSoundNumber=ll
--> Setting the SequenceContactNumber to anything greater than zero, causes the input # dd to operate in a
sequencing mode.
--> FirstSoundNumber sets the first wav file number to be played in the sequence as # ff.
--> LastSoundNumber sets the last wav file number to be played in the sequence as # ll.
You would replace dd with the contact input you wanted to function this way, ff with the first sound that you
wanted it to play, and ll with the last sound you want it to play. Every time there is a contact closure on the
input specified in dd, it will play the files from ff to ll in sequence, then start over again at ff, and keep
repeating. See the Sequential Sound Playout section above for more information.
Q. Can I use a momentary contact closure to initiate a message, but the message needs to stop by using
another momentary closure (or open?). So, a momentary to initiate, and a momentary to stop any

message that is in progress ?:
Yes, the CFSound-IV can function as you described. A triggered message that is playing could be 'stopped'
by activating another short silent message associated with another contact input. Alternatively a short Acs
Basic program can be utilized.
Q. Can the Input ports be momentary, or do they need to remain in a closed or open ?:
It depends upon what you're trying to do. If you want a message that is triggered by a contact closure (or
opening) you only need a momentary switch.
If you want the sound to only play while the input is closed (or open) then you would need a latching switch.
Sounds are associated with inputs by the filenames of the sounds on the SD card. How they are activated is
also controlled by 'decorating' the filenames with additional characters.
For example:
To play a sound whenever input 1 momentary closes, the sound file would be named 01C.WAV.
To play a sound whenever input 2 momentary opens the sound file would be named 02O.WAV.
To play a sound only while input 1 is closed, the sound file would be named 01CP.WAV.
To play a sound only while input 1 is open, the sound file would be named 01OP.WAV.
To repeat a sound only while input 1 is closed, the sound file would be named 01CPR.WAV.
Sounds are normally interruptible whenever another input is activated, but you can also add the character "N"
to the filename and make the sound(s) non-interruptible.
You can also control the unit through the RS-232 port to start and stop sounds.
Q. Can a background sound or music be played until another input is triggered ?:
You can have one or more background sounds that play (with an optional delay in between). The
background sound is interrupted by the contact input activated sound(s), and resumes (if active) when the
contact sound is finished playing.
Q. Can we use basic switches to control our various functions. There are no logic circuits, or anything
"hi-tech" in this design ?:
You shouldn't need any external logic circuits. We use 'dry' contact closures for the inputs and provide 'dry'
contacts for the output(s). Simple off the shelf switches will work just fine. Water tight / weather proof
switches should be used if exposed to elements of weather.
Q. Can individual audio files/channels play simultaneously? i.e. can a file be triggered to play,
overlapping a file or files that are already playing ?:
The CFSound cannot play files simultaneously, but it does offer several features that get around this
limitation.
1) When the a background sound/file is playing, and it is interrupted by a contact input, it pauses the
background sound, plays the sound triggered by the contact input, then continues playing the background
sound from where it was interrupted.
2) When sounds are played by an external contact input/trigger, they can be configured by:
Characters in their filename to be:
a. Not interruptible
b. Interruptible (the default)
There are settings controllable by entries in the CFSOUND.INI file to:
a. Store inputs/triggers, and play them when the current sound in finished
b. Not store inputs/triggers while a sound is being played

Q. I am having addressing problems. With the 'old' units I was able to run a lead from common to
'0nCPR' and have the unit start playing a track "n" automatically on power up. This does NOT
happen with these units. It seems there is something wrong with addressing operation. Is there any
adjustment I can make ?:
We did indeed make a software change that pre-reads the contact inputs on power-up to prevent automatic
sound activation if contacts where already closed. We had a customer complain about this 'feature'.
To support this un-documented feature, we added an additional CFSOUND.INI file entry of:
[Contacts]
Force=TRUE/FALSE
--> Setting this value to TRUE restores the original behavior wherein the contact's active status is 'forced'
upon reset, power-up or card-insertion. This will cause associated sound activation if the contact was active.
--> Setting this value to FALSE (the default) causes the new behavior wherein the contact's current status is
sampled upon reset, power-up or card-insertion. This will cause no associated sound activation until the
contact is re-activated.
Q. Do you have more detailed spec's on your amplifier module ?:
The stereo amplifier is based upon Analog Devices SSM3302 Class D Amplifier and provides 10W per
channel to bridge tied speakers (no ground reference).
Q. How do I use the Windows Sound Recorder to make recordings ?:
1. Click on the Start Button, then Programs, then Accessories, then Entertainment, then Sound Recorder.
2. Click on Files, then Properties. A new window opens named "Properties For Sound".
3. Change the "Format Conversions" "Choose From" drop down box to "All Formats" or "Recording
Formats".
4. Next, click on "Convert Now", a new window named "Sound Selection" opens.
5. Make sure "Format" is PCM, 44.1KHz, Stereo or Mono.
7. Click on the OK Button to close the "Sound Selection" window.
8. Click on the OK Button to close the "Properties For Sound" window.
9. To start recording, click on the button with the red dot(record).
10. To stop recording, click on the button with the black square(Stop).
11. Once you have finished recording, Click on File, then Save As, and name your file how you want it to
play.
12. I.E. "01B.WAV" to play when there is no switch closures.
13. I.E. "01C.WAV" to play when input #1 closes.
14. Copy the file to the Compact Flash Card.
You're done.
NOTE: If you click on File, then click new, you will have to set the File properties again before recording.
Please see the videos on the SUPPORT page of the CFSOUND.COM website.
Q. Can a output contact be used to operate a lamp to indicate that the message has been triggered ?:
If you need individual lights that illuminate when the associated input is active, you would need the
Contact I/O 8 module in the CFSound-IV. If you only need a single light that is illuminated whenever any
sound is playing then you can use the PTT relay that is installed on the main unit and use a Contact Sense 8
or Contact Sense 24 module.
Q. We have a client who has a specific need -- an interval timer function. They want their very short
message to go off every 30 minutes (not seconds). Does your equipment have a provision for an interval
timer ?:
By placing a file named CFSOUND.INI on the compact flash card along with your sound files, you can
control several operating features of the unit.
For your application the following entry would provide the 30 minute delay between the background sound:
[Background]

ACS CFSound-IV Compact FLASH Digital Audio System

BackgroundDelay=1800
This .INI file option sets the delay in seconds between background sound play-outs to the decimal value of
1800 seconds (30 minutes). The default is 0 seconds (no delay). This is not a high-resolution timer and may
be affected by other sounds playing while the timer is active. The specified time is between background
sound starts.
Q. We need to have a light associated with an individual "message initiate" momentary switch when
that message is playing. Do we need only the Contact I/O 8 module, or do we also need the Contact
Sense 8 ?:
The Contact I/O 8 has 8 contact sense inputs and 8 contact outputs. The Contact Sense 8 has 8 contact
sense inputs and the Contact Sense 24 has 24 contact sense inputs. The CFSound-IV revision 2 can accept
one I/O module, the CFSound-IV revision 3 can accept two I/O modules.
Q. I ordered an enclosed CFSound-IV, and no volume control knob was installed/received ?:
We do not ship a volume knob with the CFSound-IV, since the volume may be adjusted by pushbuttons on
the front of the unit.
Q. When wiring the power supply connector to the supplied power supply, which side is plus and
which side is ground ?:
Please see the MAIN connector description earlier in the manual for correct power supply wiring.
Q. Will it finish playing the current file even if another input is tripped half way through the file ?:
If you add an "N" in the filenames of your files, it marks the files as non-interruptible. Then optionally
setting SaveNIContacts= TRUE in the [CONTACTS] section of the ini file, will cause contact closures
occurring during play out of the Non-Interruptible file to be saved until it completes playing, triggering the
subsequent file(s).
Q. How long does it take the CFSound-IV to power-up and be ready to play sounds ?:
The unit must either scan the card upon power-up, or scan the card every time a sound is initiated. We
opted to scan the card upon power-up to enable each sound to be played quicker. Many of the delays upon
power-up are due to having to support the variety of Compact Flash cards on the market - some of which
require several seconds upon power-up before they are accessible. The firmware is designed to accommodate
the worst case card, and we've had to slow it down in production as people encountered problems with
various cards that couldn't be read. There is no firmware modification available that will shorten this delay. A
freshly formatted small card with a limited number of sounds will scan the fastest. We have measured this
delay at 5-15 seconds.
Q. How long does it take the CFSound-IV to play a sound in response to a contact closure ?:
The unit debounces the contact inputs by sampling them every 20mSEC. It requires a three sample
sequence of open, open, closed to qualify a contact input as valid. Then the file must be opened and buffering
started. We have measured this delay at ~100mSEC.
