Overview
Thank you for purchasing the Compact FLASH II 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 Compact
FLASH 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, 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. Once the files are copied to the Compact
FLAS H Card, they are renamed. This process instructs the Compact FLASH II Digital Audio System
how and when to play the copied files.
Features
The Compact FLASH II Digital Audio System incorporates the following features:
Uses inexpensive, industry standard Compact FLASH (CF) Cards up to 512meg in size.
A 32meg CF Card provides up to 69 minutes of audio at an 8KHz sampling rate and up to 34
minutes at a 16KHz sampling rate.
RS - 232 Serial Port for controlling audio play out via an attached computer or PLC.
Diagnostic LED s to indicate operating status.
Built - in dual contact input.
Push To Talk (PTT) relay contact that can optionally close whenever a sound is played.
Built - in Stereo Amplifier for 4 or 8 ohm speakers .
Optional board for contact inputs to activa te sounds.
Optional board for contact outputs activated with sound for sound steering or other control.

Main Connector
Most of the connections to the CFSound- II are supplied to the unit with a ten pin, 2 piece plugg able
terminal block style connector Main .
Power Supply Connection
The CFSound II requires a regulated or unregulated voltage of 10V to 18V DC. The unit has resettable
fus ing internally to protect the Power input. Should the fuse trip, remove power, wait a moment for the
fuse to reset, then re-apply power. The non-OEM version of the CFSound II is supplied with a wall
mounted transformer rated at 15VDC @ 0.8A.
ACS supplies two different versions of the wall- mounted transformer power supply for the CFSound-
II. 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- To -Talk (PTT) 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. 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-II 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
optoco upler 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

emitters connected to ground and are buffered by an inverting gate. The following diagram is

The input is activated by sinking current from the Contact input pin to ground. A Ground connection is
supplied on p in 5 of the Main connector for this purpose. The input current sink requirement is
approximately 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 4 watts.

Serial Connector
A standard RS - 232 serial interface is provided on - board via the DB - 9 style male Serial connector. The
CFSound II 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 II via the serial port. The format of the serial data is 2400 baud, 8 data bits and 1 stop bit. Only
three of the nine pins are used. The configuration of jumper block JB2 on the CFSound II controls whether
the serial port looks like a Modem (DCE) or a Terminal (DTE).
As shipped, the CFSound II is configured to be DCE so that a one- to -one cable from a PC serial port may
be used. The pinout for the Serial connector is:
