Introduction

Thank you for purchasing the 7K Digital Audio Board (DAB).

The DAB has been designed as a “drop-in” replacement for the Speech Synthesizer board in the S-Com 7K repeater controller, but does more than just talk.

The DAB utilizes a fast, FLASH based, single chip microprocessor to support audio playback from a FLASH based Multi- Media Card (MMC) which is used to store digitized speech files played back in response to commands from the 7K repeater controller.

The MMC media card is the same type of solid state storage media that is used in many consumer devices such as cameras, personal digital assistants, and MP3 players. The file system used on the FLASH card is the same FAT16 file system used on desktop computers for years and is thus compatible with any third party MMC I/O device that supports this type of file system. The FAT16 file system constrains the total storage space to approximately 2 Gigabytes, which provides the potential to store hours of audio material. The user is free to upgrade the amount of storage space available at any time simply by purchasing higher capacity FLASH cards from the vendor of their choice.

The audio files are stored in the well-known WAV file format, which is a subset of the Microsoft Resource Interchange File Format (RIFF) file format. This flexible file format supports dozens of different audio compression methods, of which the DAB supports only a few specific types.

The DAB also has an RS-232 serial port that can be used to send or retrieve files from the FLASH card in order to allow the update of audio files, product firmware, and to make product configuration changes.

The DAB’s product firmware is fully field updateable and new firmware revisions can be installed by the end as they become available.

If you have any questions or comments regarding this product, please know that your feedback is always appreciated.
