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.
