The ‘DMS6KREL V1_??.HEX’ file is the firmware for the system and can be replaced with
a new file to add more features as and when they become available. See ‘Firmware update’
The ‘INIT DMS6K.TXT’ file is used to configure the operation of the DMS6000. See
‘Configuration file’.
The ‘DATA’ folder will contain all of the audio files, control files and command files.
Audio file format
The DMS6000 currently supports .MP3 (Mpeg 1 Layer 3) files.

32KHz, 44.1KHz and 48KHz.
Bit rates
32, 64, 96, 128, 160, 192, 224, 320 Kbps
Audio files
The mp3 Sound files must be named in the following manner to enable the DMS6000 to
identify the files.
The first 3 digits in the file name assign the file to its trip input number.
Codes 001 to 008 are possible for direct trip inputs.
Codes 001 to 255 are available if using binary or command files.
The next string of characters are used for your file name, only the first 16 of these
characters will be displayed on the 2x16 LCD display if fitted.
The last 4 characters must be .mp3 for a valid file name.
Example 1:
001 TEST MESSAGE.mp3
Example 2:
156 This is a test.mp3
Both the above are valid file names for messages 1 and 156 respectivley.
