Overview

Thank you for purchasing

the

Compact FLASH

III

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 o

r program the device.

End users can change the audio themes or tracks simply by inserting another, different Compact

FLASH Card, as easily as the changing of a cassette tape. Multiple cards can be programmed with

different audio themes or tracks allowin

g 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, Compact FLASH

Cards may be re

used up to 10

,000 times.

Sound files are easily copied onto the card via your PC or laptop, using a Compact FLASH to

PCMCIA, Compact FLASH to USB or parallel port adapter.

the files are copied to the Compact

FLASH Card, they are renamed. This process instructs the Compact FLASH

Main

Power Supply Connection

The CFSound III requires a regulated or unregulated voltage of 10V to 18V DC. The unit has

resettable fusing internally to protect the Power input. Should the fuse trip, remove power,

correct the fault,

wait a moment for the fuse to reset, then re-apply power. The non-OEM version of the CFSound III is

supplied with a

wall

mounted transformer rated at 12

VDC @

1.0

ACS supplies two different versions of the wall-mounted transformer power supply for the CFSound-

. The version in the black enclosure has a white stripe on the positive lead which should be connected to

pin 9 of the

Main

connector with the other lead to pin 10. The version in the beige enclosure has a black

stripe on the negative lead which should be connected to pin 10 of the

Main

connector with the other lead

to pin 9.

Built

in Contacts Connection

The

Push

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 C

ommon and Normally Open relay contacts are a

vailable on the

Main

connector.

The contact inputs on the

Main

connector appear logically to the CFSound-

I 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 pullup resistors on their collectors, with the

The input is activated by sinking current from the Contact input pin to ground. A Ground connection is

supplied on pin

of the

Main

connector for this purpose. The input current sink requirement is

appr

oximately 15 mA.

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 20 watts. NOTE THAT THE SPEAKER OUTPUTS ARE

Serial Connector

A standard RS-232 serial interface is provided on-board via a DB-9 style male connector.

The

CFSound

III

provides diagnostic messages about CF card insertion and removal events and sound contents

over the serial port. Additionally, the playing of sounds may be controlled by messages issued to the

CFSound

III

via the serial port. The format of the serial data is 2400 baud, 8 data bits and 1 stop bit, and

the baud rate may be changed using a configuration file entry or NVM setting. Only three of the nine pins

are used. The configuration of jumper block JB2 on the CFSound

III

controls whether the serial port looks

like a Modem (DCE) or a Terminal (DTE). As shipped, the CFSound

III

is configured to be DCE so that a

-one cable from a PC serial port may be used. The Windows HyperTerminal accessory may be used

to view the diagnostic messages and

manually issue commands to start/stop/queue sounds

Remote Volume Connector

The sound volume level is controlled by two pushbuttons on the front of the CFSound-III: 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-III and is restored to it s 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. Connecting a momentary button between the input and ground parallels the operation

of the on

board volume controls

Compact Flash Card Requirements

The

Compact FLASH III Digital Audio System was designed to use only Compact FLASH Cards

(CF Cards) that support the True IDE ATA mode at 3.3 volt operation. Tested cards include San Disk,

Kingston, Techworks, Dane-Elec, Memorex and Hitachi. The San Disk card was tested, since they

manufacture 90% of the retail cards on the market. Compact FLASH Cards are available in many local

electronics or camera stores or can be ordered directly from ACS.

LEXAR Media Compact Flash cards are not 100% compatible in True IDE mode and as such

are NOT COMPATIBLE with the Compact Flash III Digital Audio System.

Programming the Compact FLASH Card

The Compact FLASH Card is programmed by inserting it into the PCMCIA slot of a Compact FLASH

to PCMCIA adapter or a Compact FLASH adapter connected to your parallel port. Sound files are copied

to the Compact 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 Compact 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 Compact 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

Compact FLASH Card 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

III

Digital Audio System.

Installing and Removing the Compact FLASH Card

Care should be taken when installing or removing the Compact FLASH Card. Please be certain to

insert the card with a straight and level motion. Please do not force the card to insert. Otherwise, some of

the 50 pins in the socket may become damaged and the card and/or Compact FLASH

III

Digital Audio

System

may become unusable.

Before REMOVING the Compact FLASH Card under Windows 95 or later, Microsoft recommends

that you double click on the PCMCIA icon at the bottom of your computer screen. This will bring up the

pc card [PCMCIA] properties window. Click on socket status tab, then select the card you wish to remove

by clicking on it. Finally, click on the stop button. Windows will then tell you that the card socket

services have been stopped.

On the Compact FLASH

III

Digital Audio System this will all happen automatically simply by

removing the card.

Audio Rates Supported

The Compact FLASH

III

Digital Audio System supports

bit

mono

stereo

Windows PCM

format (.WAV) sound files at a sampling rate of

44.1

KHz (

44,100

Hz)

only

The

Compact FLASH

III

Digital Audio System reads the sampling rates and formats encoded in the .WAV sound files whenever a

card is first inserted or a sound playout is triggered. The Compact FLASH

III

Digital Audio System 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.

Formatting the CF Card

Compact

FLASH cards must only be formatted using the FAT12 (floppy) FAT16 or FAT32 file

system. NTFS file system formats are not supported. The maximum supported partition size is 4G. The

CFSound

-III will attempt to locate a valid, active partition on the formatted card in order to be able to

access the files. CF cards that have been previously used in some digital cameras may not be correctly

formatted, or have valid partitions defined.

By default, Windows XP will format any Compact Flash card of 64MB or more with FAT32 format.

The ACS Compact FLASH III Digital Audio System uses the FAT (FAT16 or FAT32) format and can not

operate with a NTFS formatted card. You must select FAT file system to format your Compact Flash card

in a Windows XP PC.

Modes of Operation

The

CFSound

III can operate in one of two different modes:

Conventional CFSound where the sound playout is controlled by the association of contact

numbers and sound filenames.

This is referred to as the

CFSound Mode

Scriptable CFSound where the sound playout is controlled by the execution of ACS Basic

programs.

This is referred to as the

Basic Mode

Upon power-up, reset or whenever a Compact Flash card is inserted or removed, the unit determine

its operating mode as follows:

If a CF card is not present, th

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.

If a

CF card is present

the unit looks for a file named

CFSOUND.BAS

and, if

found

, starts t

he ACS

Basic interpreter, loading the file and executing the Basic program within

in Basic Mode

If a

CF 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.

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

in Basic Mode

These two modes of operation are detailed in the following sections.

CFSound Mode

In CFSound Mode, the operation of the CFSound-III is controlled by the names of the sound files on

the

CF 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 CF card along with the sound files to

further control how the unit plays sounds.

Filename Formats

The filenames of the individual Sound files on the Compact FLASH Card control how and when the

sounds are played out by the Compact FLASH

III

Digital Audio System. The filenames must start w

ith

the optional input number they are associated with expressed as

a two digit HEX number

Compact FLASH III Digital Audio System

2007

by ACS, Sarasota, Florida

The HEX numbering system has a base of 16 as compared to the decimal system which has a base of

ten. A HEX numeric digit is 0 through F, 0 being equal to decimal 0, 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:

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.

The two digit hex input number must be the first two characte

rs 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

III

Digital Audio System

provides

one

input in its standard

configuration and, by adding an opt

ional board, can be expanded to either

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

III

Digital Audio System to the RS-

232 port of your computer or PLC to control up to

255

sounds using serial commands.

The filename letter tokens are described as follows:
