  • Page 6: Introduction

    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.

  • Page 7: Copyright Notice And Limited Software Warranty

    Limited Hardware Warranty Vyex LLC warrants that its products will be free from defects in materials and workmanship for a period of one year from the date of shipment. This warranty does not cover damage caused by any of the following: Physical damage of any kind.

  • Page 8: Trademarks

  • Page 9: Installation Into The Rack Mount Cabinet

    Installation CAUTION: The DAB is a static sensitive electronic device. Proper precautions should be exercised when handling the DAB. Installation and connection of the DAB can only be performed with power removed from the controller. Installation into the rack mount cabinet. The DAB is installed in the controller cabinet to the left of the repeater controller circuit board and secured in place with four 6-32 screws.

  • Page 10: Installing The Flash Card

    Installing the FLASH Card The multi-media FLASH card should be inserted into the connector as shown, with the gold contacts facing downward. When the card is not installed in the DAB, do not touch the gold contacts. 7KDAB, Version 2.0, 19-Aug-2007 Vyex LLC, 2003-2007...

  • Page 11: Updating The 7K Repeater Controller Firmware

    Updating the 7K repeater controller firmware An EPROM containing new firmware for the 7K has also been included with the DAB. This new firmware provides better integration between the DAB and 7K controller as well as providing new, generic, features to the 7K itself. When version 2.04 firmware is installed in the 7K, the 7K will need to be re-initialized before it will work, and the user will need to reload their program into the controller.

  • Page 12: Led Status Indicator

    Using the DAB LED Status indicator The DAB has a dual color surface mount LED mounted near the board edge near the FLASH card connector. If the FLASH card is present upon power up, the dual color LED on the DAB should briefly illuminate green as the FAT file system code initializes its internal variables.

  • Page 13: Basic Use

    Basic use In its simplest form, the DAB will mimic the original S-Com speech synthesizer board, and thus it is compatible with any version of 7K firmware that supported the speech board. The default speech library included with the DAB includes digitized versions of the original TI speech synthesizer vocabulary.

  • Page 14: Things To Consider When Deciding File Storage Parameters

    Supported WAV File formats For those that wish to create their own WAV files, you will need to know about some specific constraints of exactly what the DAB does and does not support. PCM. 8 or 16 bit linear (uncompressed) values, in either mono or stereo format. The maximum supported sample rate is 22.05kHz.

  • Page 15: Recommended Editing Programs

    Recommended editing programs Adobe Audition, formally Syntrillium Software’s Cool Edit Pro product, is a preferred tool we use here. http://www.adobe.com/ SoX – Sound eXchange is a useful tool that claims to be the “swiss army knife of sound processing programs”. This useful utility can convert from just about any sound format to another format, change sample rates, pitch, speed, filter, etc.

  • Page 16: File System Requirements

    File system requirements The Multi-Media Card needs to be formatted with a DOS FAT16 file format. For smaller media types, the default of the format program you utilize may format the card with a FAT12 file system, and you will need to override the default settings.

  • Page 17: Special Files Stored In The Root Directory

    File system structure for the Audio Files The WAV files need to be stored in a predetermined manner in order on the FLASH card. The Root directory needs to contain a “WAV” subdirectory, and the WAV subdirectory needs to contain additional four digit numeric subdirectories corresponding to the “hundreds”...

  • Page 18: Long Word Continuation

    DAB-BOOT.BIN This file contains the small bootstrap loader used to reprogram the microcontroller. If this file exists, its contents are checked against its program storage space in FLASH memory. If they are different, the microcontroller will reprogram this portion of the FLASH memory. 7K-IMAGE.BIN This file contains an image of the 7K controller’s battery backed SRAM.

  • Page 19: Playback Speed Factor

    9702 – Playback Speed Factor When this word is spoken, the word that follows it is used as a playback speed multiplier against the playback rate specified in the WAV file header. The word value supplied is specified as a percentage of the playback speed with 0100 (100%) being the normal playback rate.

  • Page 20: Send Serial Characters

    9720 – Send Serial Characters In order to allow a modem to share the same phone line that the repeater controller is connected to, one or more macros will need to be created in the 7K to cause the modem to answer, or place a call on its own. Once special word 9720 is encountered, the decimal of each word encountered after it will be used to determine which ASCII character to send on the serial port.

  • Page 21: Provide Rtc Data To Dab

    Notice: The following special word commands were included to aid in the overall firmware development process and are somewhat experimental. While they are implemented, they are not supported at this time, but are documented here for the sake of completeness. Whenever any of these special word commands are issued, 100% of the 7K’s CPU time is dedicated to executing the associated command.

  • Page 22: Message File Control Characters

    Morse Code Features Message File Location Text files containing the desired message along with special control sequences to control pitch, speed, and amplitude can be stored in the same directory structure along with the audio files. As with the audio files, the Morse code filenames begin with the four digit numeric value of the desired phrase number, but in this case use the file extension “CW”.

  • Page 23: Sending 'Prosigns

    Speed Two different control characters are supported for setting the speed. For normal cadences, the percent sign ( % ) is used to select a speed ranging from 1 to 50 words-per-minute. For code practice purposes, the inter-character speed may be supplied separately by using the asterisk ( * ) character to select a speed ranging from 1 to 50 words-per-minute.

  • Page 24: Kdab 'Busy' Message

    7KDAB ‘Busy’ message If the 7K attempts to command the 7KDAB to play a file while the 7KDAB is otherwise preoccupied with another action which requires the use of the FLASH file system (such as the user uploading new files to the card), after waiting for 2 seconds, the 7KDAB will play a short CW message in place of the desired word.

  • Page 25: Using The Serial Port

    Using the Serial Port Hardware Interface Connecting the DB-9 serial port connector to a PC type computer can be accomplished with a straight through cable. The DB-9 connector pinout is as follows: 1. No Connection 2. Transmit Data from DAB 3.

  • Page 26: Connecting A Modem To The Serial Port

    Connecting a Modem to the Serial Port Since every modem tends to be a bit different, it is not possible to provide a single example that will work for everyone, but we can point out the important steps that need to be taken. First, the modem itself needs to be configured as follows: Fixed DTE Speed.

  • Page 27: Cd – Change Directory

    The Command Line Interface Using the Command Line interface (CLI) the user can effect the management of files on the FLASH card. Upon gaining access to the DAB’s command line interface the user is presented with the prompt: 7kDAB-> As a preface to the list of the following commands, it is important to note that the file system software in the DAB is single threaded.

  • Page 28: Dir – Directory Command

    DIR – Directory command While similar to the directory command under MS-DOS, this command does not accept any parameters. It simply lists all the files within the present working directory. Example: 7kDAB-\>dir MMC Card MID: 6, PNM: KODAK , PSN: 428348449 08/19/2003 14:04 [D----]...

  • Page 29: Del – Delete File

    DEL – Delete File While similar to the delete file command under MS-DOS, this command will only delete files in the present working directory, and will not accept wild cards. Example: 7kDAB-WAV\4300>del 4380.wav File Deleted REN – Rename File While similar to the delete file command under MS-DOS, this command will only rename files in the present working directory, and will not accept wild cards.

  • Page 30: Smhost – Force Smart Host Present Flag

    SY – Send Y-Modem Allows a file to be sent from the DAB to the users computer via the serial port. Most any popular terminal program written in the past 10-15 years will support Y-Modem file transfers. Since each program is different, please consult that software’s documentation for use of the file transfer capabilities of your terminal emulation program.

  • Page 31: Time – Display Or Set The Current Time And Date

    STOP – Stop current WAV file playback Immediately terminates the playback of any WAV file. This may be useful if the command line user wishes to interrupt the playback of a long WAV file in order to gain access to file management commands. TIME –...

  • Page 32: Command Line Interface Commands Available With 7K Firmware 2.04

    Command line interface commands available with 7K firmware 2.04 #!; - Issuing commands to the 7K Perhaps one of the more appealing additions to the 7K firmware, when used in conjunction with the DAB, is that commands to the 7K can be entered on the serial port. Any digits preceded with an exclamation point will be sent to the 7K and treated as DTMF digits that appear to originate from within the controller.

  • Page 33: Rfp – Remote Front Panel

    RFP – Remote Front Panel The remote front panel command allows real time viewing of the controller activity via the serial port. When this command is invoked a representation of the controller’s front panel, along with some additional data is displayed on your screen. A group of three reverse video spaces is used to form a block to denote an indicator that is ‘lit’...

  • Page 34: Script – Execute Text File To Program The 7K Controller

    “Hyperterm” users will need to visit the Hilgraeve website http://www.hilgraeve.com/ and download a current version of this free terminal emulator in order for all characters to be properly displayed. For many years, Microsoft has bundled Hilgraeve’s terminal emulation software with Windows, and those bundled versions have some issues with some of the commands that the DAB uses.

  • Page 35: Mmc Card Reader/Writer Attached To Your Computer Running Windows

    Firmware Update Procedure. The product firmware can be updated by placing a new firmware image file in the root directory of the MMC card. This can be accomplished in one of two ways.
